Description

  The present invention relates to a brewing apparatus, and more particularly to a brewing apparatus that makes use of the advantages of acrylic resin among permeable materials in order to allow visual observation of the state of fermentation and agitation in a container during the fermentation process of brewing.

  Since ancient times, wooden or metal barrels have been used for brewing alcoholic beverages. In general, alcohol fermentation in which carbon dioxide gas is generated by replacing sugars with alcohol is generally used for fermentation of alcoholic beverages. However, in sake brewing sake, since the raw material rice does not contain sugars, the two chemical reactions of saccharification to convert starch from rice into sugars by persimmon enzymes and alcohol fermentation using yeast are the same at the same time Using a production method called parallel double fermentation which is carried out in a container, such parallel double fermentation is an advanced brewing method unique to sake brewing in other countries.

  The cocoon-making process in parallel double fermentation involves changing the state of saccharification and fermentation of cocoons that change during the period from the initial addition of cocoons, sake mother, water, and steamed rice into the container to the end of the preparation process (hereinafter referred to as “ An operation is performed to confirm "fermentation state" as a term including both "saccharification" and "fermentation" states. In addition, since saccharification and fermentation involve temperature changes, the koji changes in specific gravity, and such changes in specific gravity cause convection in the koji in the container. Therefore, about twice a day of stirring work is required.

  The stirring operation may be performed by artificially using a crucible into a crucible, or a method using an automated mechanical stirrer. In the artificial stirring method, it is possible to grasp the stirring state of delicate chopsticks by the feeling transmitted to the hands of the owner and Mr. Tsuji and sensory judgment based on long experience, and according to the mechanical method, under certain conditions It can be said that each has an advantage that the stirring state can be repeated accurately. However, regardless of which method is used for stirring, in a brewing apparatus using a solution made of wood or metal, the state of these stirring from the side (hereinafter referred to as “stirring” in the term of “stirring state” And “convection” shall not be visually observed.

  Therefore, if the container can be observed from the side, it is possible to more accurately grasp the fermentation state and the stirring state, and it is possible to achieve the improvement and stabilization of the quality. Then, the technical proposal of the brewing apparatus which can visually observe a fermentation process from the outside is awaiting. However, glass is easily broken, and resin is considered to be soluble in alcohol, and it has been recognized that it has been recognized as a material that can not be used in sake brewing.

  Then, conventionally, the technical proposal regarding the various brewing apparatus which makes a fermentation state etc. visible is made | formed. For example, the name of the device is "the respirator of the fermentation tank", and specifically, by making the tubular part transparent, it is possible to visually observe the respiration state in the fermentation tank by making the tubular part transparent. The technology of the device is disclosed (see Patent Document 1). However, such a technique is capable of observing the respiratory state in the container by making the tubular part connected to the container transparent without being permeable to the container, and the fermentation state over the whole of the body And it has not come to solve the said subject which makes the stirring state visible.

  In addition, the title of the invention is "visible safety device for a cold thermal dual duct for biofermentation tank", and specifically, a technique for making it possible to visually check the flow state of two ducts for cooling and heating is disclosed and known. (See Patent Document 2). It can be said that the subject of the present invention is common to the related art in that the internal state which has not been seen in the past can be viewed visually. However, such a technique is capable of observing the flow state of hot water or refrigerant through a scope, and has not been able to solve the above-mentioned problem of making visible the state of fermentation and stirring throughout the entire body.

  In addition, the title of the invention is "indivisible beer fermentation apparatus", specifically "beer fermentation apparatus capable of visualizing the inside, and having an annular transparent visible window in the tank body Patent Document 3 also discloses a technique for making a fermentation apparatus capable of observing the fermentation state of beer. Such a technique is also common to the problem of the present invention in that a transparent window is provided in order to make the inside of the tank visible, and this is to be solved. However, it is difficult to observe the whole inside of the tank with this technique, it is difficult to observe the convection in the tank due to fermentation, and the problem of making it possible to visually check the state of fermentation and stirring all over the container is solved. It has not been done yet.

  In the present invention, a permeable material is used for the container 10, and thus fermented product H such as koji that has been introduced into the container 10 (hereinafter, "fermented product" is used as a term including "koji"). The most important feature of the present invention is that the fermented state and the stirred state of (a) are made visible from the outside. Hereinafter, it demonstrates based on drawing. However, the present invention is not limited to the shapes and configurations described in the drawings, and can be changed within the range in which the effects exhibited as the creation of the technical idea of the present invention can be obtained.

  FIG. 1 is a basic configuration explanatory view for explaining the basic configuration of a brewing apparatus 1 using a permeable material according to the present invention. As shown in FIG. 1, the upper part is comprised by the container 10 which accommodates the fermented product H, and the mount frame 20 which mounts this. The overall size is determined according to the desired production volume, and it is necessary to have a strength that can withstand the weight based on such production volume.

  FIG. 2 is an explanatory view for explaining the configuration of the container 10 according to the present invention, and FIG. 2 (a) shows the configuration when the container 10 is viewed from the lateral direction, and a container bottom member 13 disposed at the bottom of the container 10. 2B shows a state in which the packing member 30 and the coupling member 31 are coupled, and FIG. 2B shows a cross section when looking downward from the approximate center of the cylindrical portion 11.

  The container 10 is a container for containing sake mother, rice bran, water and steamed rice, and fermenting the rice bran, and a cylindrical part 11 using a permeable material visible from the outside, and a container bottom member 13 at the bottom. It comprises a flange-shaped portion 12 for coupling, and an upper flange 14 for mounting a lid at the top. The cylindrical upper portion 11, the upper flange 14, and the flange-shaped portion 12 can be used not only separately but also as a container 10 having a configuration in which they are integrally formed. Further, although the container 10 is shown in a cylindrical shape in the drawings, the shape of the container 10 may be a polygonal column, and is not particularly limited.

  The cylinder upper portion 11 is a main component of the container 10 and is a cylindrical body formed of a permeable material so that the inside can be seen, and if the cylinder upper portion 11 has a cylindrical shape, it circulates in the market An extrusion molded article or a cast molded article may be used. In addition, in order to make it into a special size and shape, it is necessary to form using a special chemical process because of the characteristics and the like according to the type of resin.

  The flange-shaped portion 12 is a flange provided at the bottom of the container 10 for coupling with the container bottom member 13, and in the flange-shaped portion 12 concerned, a hole for coupling with the container bottom member 13 by the coupling member 31. A plurality of are provided. However, the present invention is not limited to the configuration in which a flange is integrally formed at the end of the container 10 as shown in FIG. 2, but a means of forming a flanged member at the opening edge of the container 10 by welding or bonding is also effective. It is.

  The container bottom member 13 is a member coupled to the container 10 so as to be in a watertight state by the coupling member 31 with the packing member 30 interposed between the container bottom member 13 and the flange-shaped portion 12 provided at the bottom of the container 10.

  Permeable resin is lighter than glass, easy to calculate strength, hard to break, and easy to handle, so it can be said to be a suitable material for container 10 according to the present invention. . Since there are many types of such permeable resins, it is necessary to satisfy the two conditions required as particularly suitable materials. The first condition is to have a permeability for making it easy to observe the fermentation state and the agitation state of the fermented product H, and the second condition is a chemical resistance that is not affected by the alcohol and the like involved in the fermentation. It is excellent in sex.

  Therefore, when considering the resin under the first condition, whether the resin has permeability is roughly classified depending on whether it is a crystalline resin or an amorphous resin, and the permeability largely differs depending on the difference, and in general, it is crystalline In the plastic of the present invention, the crystal part and the amorphous part are mixed in the inside of the plastic, and light is irregularly reflected at the boundary and becomes opaque due to the difference in refractive index, and it can be said that it is not suitable for the material of the container 10 of the present invention. Therefore, a material having excellent strength is selected from non-crystalline resins which have uniform refractive index, transmit light, and become transparent.

  Particularly, resins having excellent permeability include PC (polycarbonate: polycarbonate (89% of transmittance)), PET (polyethylene terephthalate: pet (90% of transmittance)), PVC (polyvinyl chloride: vinyl chloride (82% of transmittance) And PMMA (polymethyl methacrylate: acrylic (transmittance 93%) or less, "PMMA" is expressed as "acrylic").

  The above four types of resins exemplify resins having a transmittance of more than 82%, and in particular, an acrylic having a transmittance of 93% has the highest transmittance in that it has a transmittance of more than 92% for glass. It can be said that it is a resin material that can be evaluated to satisfy the condition of

  Next, consider the second condition. In general, the resin loses its permeability when it comes in contact with an acidic substance or alkaline substance, and many of the resins have a whitening property. In addition, alcohol is easily soluble in oil and water, loses intermolecular force between molecular chains, and chemicals such as alcohol and the like that enter into gaps between molecular chains and swell and deteriorate may affect food. . Therefore, in order to satisfy the second condition, it is necessary to select a resin that can be evaluated as being excellent in acid resistance, alkali resistance, and organic chemical resistance. Further, with regard to the safety of the container 10 in contact with food, the food sanitation law sets standard standards according to materials and uses, and it is necessary to select a permeable resin that conforms to the standard standards. The above four types of resins conform to the standards of the Food Sanitation Law.

  An acrylic resin is considered to be most suitable as a resin that satisfies both the first condition and the second condition. Then, an example of evaluation using an acrylic resin is shown below. The acrylic resin used for the evaluation concerned used the material which is provided by Nitto Jushi Kogyo Co., Ltd. and which is trade name "CLAREX" (registered trademark). In addition, the evaluation which concerns was performed by visually confirming the surface state after leaving it to stand for 24 hours, after apply | coating each chemical | medical agent on the surface of a test side with a thickness of 3 mm, and the data which concern are Nitto resin Kogyo Co., Ltd. Based on the materials provided by

  Table 1 shows the evaluation of two types of "CLAREX" (registered trademark) normal and hard materials for acid resistance, Table 2 shows the evaluation for alkali resistance, and Table 3 is the evaluation for organic chemical resistance Is shown. The symbols used in each table indicate that “◎” indicates “no change”, “Δ” indicates “slightly swollen”, and “x” indicates that “dissolution / cracking has occurred”. .

  The above Table 1 shows the influence of sulfuric acid, hydrochloric acid, nitric acid, acetic acid and oleic acid on the acid resistance, and any acid except 98% sulfuric acid, 60% nitric acid and 98% acetic acid. On the other hand, it was also confirmed that even normal materials are not sufficiently affected, and hard materials are not more affected. In addition, it is clear that alcohol, which is ethyl alcohol having a low acidity, is not affected by the acid substance as compared to the above-mentioned sulfuric acid, hydrochloric acid, nitric acid, acetic acid and oleic acid.

  The above Table 2 shows the influence of aqueous ammonia, sodium hydroxide, sodium carbonate and soap water on alkali resistance, and it was confirmed that neither normal nor hard materials were affected.

  The above Table 3 shows the influence of the organic chemicals on the solvent, and it was confirmed that either normal or hard materials were not affected to ethyl alcohol (50%).

  The manufacturer of the permeable resin used for food discloses detailed information on mechanical properties such as strength for each material. Therefore, it is important to consider the strength problem required for the case 10 as well. Specifically, whether or not the container 10 has a sufficient strength in the presence of wrinkles can be calculated from the mechanical properties of the used acrylic, the size of the container 10, the specific gravity of the wrinkles, etc. In consideration of the presence or absence of the connecting portion of the case 10, the shape of the case 10, and the like, it is necessary to design after taking into consideration the safety factor.

  FIG. 3 is an explanatory view of a connecting portion for connecting the container 10 and the gantry 20 according to the present invention. As shown in FIG. 3, the container 10 and the container bottom member 13 are screwed into the fixing hole portion 21 provided in the flange-shaped portion 12 formed at the end of the container 10 and the fixing hole portion 21 of the container bottom member 13. The state of being coupled by the coupling member 31 is shown.

  The packing member 30 is a member for water tightness, which is sandwiched between the flange-shaped portion 12 and the container bottom member 13, and exhibits performance as a general packing having elastic force such as rubber, silicon, urethane and the like. What is necessary.

  The fixing hole portion 21 is a hole portion for connecting the flange shape portion 12 and the container bottom member 13 by the connecting member 31.

  The connecting member 31 is a member for connecting the flange-shaped portion 12 and the container bottom member 13. The connecting member 31 shown in FIG. 3 is an example in which screwing members of bolts and nuts are used. is there. By adopting the connecting member 31 with such a screwing member, it becomes possible to assemble at the brewing site, and it is shown that the structure is made possible to be replaced by removing it even if the container 10 or the like is damaged or a water leak occurs. is there. Although not shown in FIG. 3, in place of such a connection, a connection means for welding the portion in contact with the flange-shaped portion 12 by heating may be used, and it is particularly limited as long as the connection means does not affect the strength and the food. It is not something to be done.

  FIG. 4 is an explanatory view for explaining the gantry 20 according to the present invention, and FIG. 4 (a) shows the shape of the gantry 20 as viewed from above, and FIG. 4 (b) is a lateral view of the gantry 20. It shows the shape. In addition, the shape of a regular octagon is illustrated in FIG. 4 (a), It is not limited to the regular octagon concerned, and the shape which gave circular, another polygon, or curvilinear design may be sufficient. , As long as the container 10 can be stably placed on the upper part thereof.

  It is necessary that the height of the case 10 be adjusted so that the height of the stand 20 can be easily viewed by the observer, and that the fermented product H is contained in the case 10 so as to have rigidity sufficient to withstand its weight. . The gantry 20 also has a mechanism for rotating the container 10, and a mechanism capable of observing the container 10 from a direction of 360 degrees without moving the observer or the video camera 50 for observation. It is valid.

  FIG. 5 is an explanatory view for explaining the specific gravity visualizing mechanism 40 according to the present invention, and FIG. 5 (a) is a cross sectional view showing a state in which the specific gravity visualizing mechanism 40 is provided inside the container 10; b) is a detailed view showing the structure of the specific gravity viewing mechanism 40, and FIG. 5 (c) is a detailed view showing the configuration of the specific gravity viewing mechanism 40 of another configuration.

  Since the koji used in sake has two processes, i.e., the process of saccharification of rice starch by koji-derived enzymes and the process of fermentation by yeast, the management of koji requires the control of glycation by koji and the activity of yeast. The balance between saccharification and fermentation can be determined by measuring the specific gravity of straw daily. When steamed rice dissolves and starch is saccharified in a basket, sugar increases, specific gravity increases, and when sugar changes to alcohol, specific gravity decreases, so it can be judged which of saccharification and fermentation is predominant. The specific gravity of straw is measured as Baume degree, and saccharification precedes from the third day to the fourth day after feed, and the Baume degree increases. After that, fermentation becomes predominant and the degree of Baume decreases.

  As shown in FIG. 5, the specific gravity visualizing mechanism 40 observes the change in the degree of Baeme's degree by the change in the position where the float gauge 44 floats up and down in the mesh cylinder 43 with the change in specific gravity of the weir. This is a mechanism for visually confirming the change in frequency from the outside. Although the drawing shows the configuration provided with the specific gravity visualizing mechanism 40 in the container 10, a flow passage to the outside is provided, and the filtration function by the replaceable filter member 45 is provided up and down. A configuration is also possible that includes a viewing mechanism 40.

  As shown in FIG. 5 (b), the reticulated tube 43 is a tube of stainless steel partially or entirely in mesh form, and the specific gravity of the filtered soot by filtering the soot with the mesh shaped stainless steel portion It is a member which guides the buoy 44 which measures. The mesh cylinder 43 is not limited to mesh stainless steel, and may have a filtering function as long as the buoy 44 can be viewed from the outside, for example, as illustrated in FIG. 5C. As such, instead of the mesh cylinder 43, the exchangeable filter members 45 may be disposed above and below the hollow permeable resin member 46, and the float gauge 44 may be floated in the hollow portion.

  The buoy gauge 44 is partially or entirely guided to the mesh stainless steel tube or hollow permeable resin as shown in FIGS. 5 (b) and 5 (c), and the mesh stainless steel or It is a measuring tool which measures the specific gravity of the filter filtered by the filtration member 45 provided to the both ends of the hollow permeable resin member 46, and a general float gauge 44 distributed in the market may be used.

  FIG. 6 is an explanatory view for explaining a configuration for distributing moving images of the embodiment of the brewing apparatus 1 using the transparent material according to the present invention on the Internet 53. As shown in FIG.

  The video shooting camera 50 is a camera for shooting a fermented state of salmon contained in the inside of the container 10, and transmits a shot moving image data to a monitor so as to construct a system capable of observing even at a distant place. Is also possible. Moreover, it is also effective to record the change of the fermentation state by video recording.

  Also, as shown in FIG. 6, the moving image data taken by the moving image photographing camera 50 is uploaded to the server 52 installed on the Internet 53 through the computer 51, and a new information service such as real time distribution is provided. It will also be possible. A special function is not required for the moving image shooting camera 50 used for distributing such moving images, and a commercially available web camera or the like may be used.

  The computer 51 is a computer or the like for editing moving image data captured by the moving image capturing camera 50 or distributing it to the server 52 for uploading onto the Internet 53. In addition, it is possible to freely set the method of distribution to the Internet 53 to be paid or not, and various methods, such as requiring certification for distribution only to researchers on sake brewing, etc. It is a system capable of providing a service aspect.

  In addition, as an applied example of the brewing apparatus 1 using the permeable resin according to the present invention, for example, it is used for a system for brewing sake dedicated to a special customer, and specific access restriction is made using electronic authentication etc. By doing so, it is also effective to provide new services with the development of information technology, such as brewing sake with a blend for individual use and enjoying the process etc. in real time through the brewing process.

  FIG. 7 is a configuration explanatory view of an embodiment in which the container 10 according to the present invention is irradiated with light, and FIG. 7 (a) shows a cross section viewed from the lateral direction, and FIG. 7 (b) is viewed from above Show the situation. Normally, brewing places such as sake are in a dark place, so lighting is required to observe the state of fermentation and diffusion. In the past, lighting in the brewing room was rarely provided with lighting equipment considered mainly for observation, and the light source used to be lighting by ordinary fluorescent lamps, incandescent bulbs, or LEDs (light emitting diodes). Most are provided on the ceiling. However, in such illumination, when the cylindrical solution is observed from the side, the whole can not be observed uniformly due to the influence of the shadow.

  Therefore, it is preferable to provide illumination for observing the whole uniformly, in order to arrange a plurality of bottom illuminations 41 at equal intervals on the outer periphery of the bottom of the container 10 so that unevenness or shadow of light does not occur in the container 10. FIG. 7A shows an embodiment in which the bottom illumination 41 uses a light source with less directivity.

  As the bottom illumination 41, it is desirable to use LED illumination which generates very little heat as a light source so as not to thermally affect the fermentation of the fermented product H contained inside the container 10. Furthermore, although not shown in the drawings, in order to make the light of the bottom illumination 41 approach natural light, it is also effective to irradiate using a diffusion plate. By adopting such a configuration, even if the shape of the cylindrical portion 11 is a shape such as a cylindrical shape or a polygonal column shape, in which the light reflection angle changes toward the depth, the observation with less unevenness and shadows While being possible, it also becomes possible to acquire the effect of interrupting the heat from illumination.

  Although the upper surface of the eyelid can be viewed as before, the surface light source and the point light source can be switched for observation in the case where the entire upper surface is observed widely and in the case where the partial state is observed with particular attention. It is desirable that the upper illumination 42 be provided with illumination means capable of such switching.

  Although FIG. 7B shows the configuration in which the bottom illumination 41 is provided on the outer periphery of the gantry 20, it is also possible to initially provide the bottom illumination 41 on the upper outer periphery of the gantry 20 in terms of design and manufacturing cost. It is effective from etc. In addition, in order to produce the process of brewing beautifully, without aiming at the observation for accurately grasping the fermentation state etc., in a dark room, irradiation of highly directional spot light using a reflector from a specific direction, illuminance It is also effective to provide lighting whose main purpose is appreciation, such as creating a fantastic atmosphere by changing the intensity of light and the color of light.

According to the brewing apparatus using the permeable material according to the present invention, high-quality sakemaking is made possible by visualizing the fermented state and the stirring state of the persimmon, which were not found in the conventional brewing apparatus for sake brewing. Stable productivity and product quality can be improved. In addition, it can also be used as a fermentation device that enables observation of the fermented state of foods accompanied by fermentation such as yogurt, miso and soy sauce, and further, used by food processing manufacturers accompanied by fermentation for the purpose of appreciating the fermented state of own products. It is possible to use it for multiple purposes, and is considered to have high industrial applicability.
