Description

  TECHNICAL FIELD The present invention relates to a method for producing an edible paste such as a flour paste that is packed inside or coated on the outside of a confectionery, bread, etc., and particularly contains a method for producing an edible paste containing a particulate solid and a particulate additive. The present invention relates to an in-line mixer for mixing edible paste.

  Flour paste, a type of edible paste that is important in the food industry, is mainly made of wheat flour, starch, nuts or processed products, cocoa, chocolate, coffee, fruit juice, potatoes, beans or vegetables, and sugar, Fats, powdered milk, eggs, wheat flour and the like are added and pasteurized by heating and pasteurized (including cream-like ones), and are used by filling or applying to bread or confectionery.

  A step of adding and mixing particles containing, for example, vanilla beans, sesame seeds, poppy seeds and other fine seeds (seeds) or solids such as natural flavorings and flavorings to such paste-like flower pastes May be required.

  The process of mixing the particulate additive with such an edible paste is often performed from the preparation stage for each type of product in the food production line. Because it is necessary to maintain the smooth texture peculiar to high-viscosity edible pastes such as flour pastes, after adding a small amount of particulate additive by batch-type mixing method for each product, mix well It is because it is thought that a non-defective product cannot be obtained unless it is done.

  By the way, in the paint manufacturing process, which is a field other than food manufacturing, there is an in-line mixer that continuously supplies fluid into an automated manufacturing line and mixes and disperses liquids in a casing having a pipe diameter similar to that of the manufacturing line. For example, in a cylindrical casing, a plurality of fixed discs with a large number of holes and a plurality of rotary discs with a large number of holes are alternately arranged along the axial direction, An in-line mixer is known in which a rotating shaft to be supported is rotationally driven by a driving device outside the casing (Patent Document 1).

  Such an in-line mixer was developed for mixing liquids, and when the fluid passes through the hole of the rotary disk, it is divided by the rotation of the rotary plate, and at that time, the fluid cross section The phase is different from that before the division, and the fluid passing through the many holes of the fixed plate from the many holes of the rotating plate is uniformly mixed.

  However, as described above, when solid particles are added to and mixed with edible pastes such as flour paste, the product cannot be continuously produced when mixed by a batch method, and when different solid particles are mixed. Requires that the entire production line be thoroughly cleaned.

  In addition, when the mixing process is performed in a spiral path such as a static mixer (static mixer) in a pipe (line) for transferring food in the manufacturing process, a long mixing line is required, and solids are contained in the line. There is a concern that the particles tend to remain and are mixed with another product manufactured in the same line, or the scent of the solid particles is perceived as a strange odor. In addition, allergens may be mixed into other products.

  If such a problem may occur, the production line must be stopped and the cleaning operation must be performed completely. At this time, it is difficult to completely clean the complicated mechanism portion.

  Therefore, there is a strong tendency to avoid supplying solid particles as needed in an automated production line. For this reason, flower paste containing various flavored solid particles according to consumer's diverse tastes, etc. It was practically difficult to produce many kinds of edible pastes in small quantities.

  Therefore, the object of the present invention is to solve the above-mentioned problems and to mix the solid particles so that the solid particles can be efficiently homogenized at a short distance as needed in a pipe (line) for transferring food. In addition, a method for producing a particulate additive-containing edible paste that is easy to clean and can be produced under favorable conditions from the viewpoint of hygiene, or an in-line mixer that can efficiently obtain a particulate additive-containing edible paste. is there.

  In order to solve the above-described problems, in the present invention, a first small-diameter cylinder having a closed end and a large number of small holes in the peripheral wall is inserted and provided in the cylindrical casing. A large-diameter portion that is open to the cylindrical casing, the large-diameter portion is fixed in close contact with the cylindrical casing, and a second small-diameter cylinder that is separately provided in the same structure as the first small-diameter cylinder is provided in the cylindrical casing. The small diameter cylinder and the tip are arranged facing each other, the edible paste and the particulate additive are press-fitted into the inside from the open end of the first small diameter cylinder, and the particulate additive is extruded outside the small hole of the first small diameter cylinder And by introducing the edible paste into the small-diameter cylinder from a large number of small holes in the second small-diameter cylinder, thereby obtaining a mixture of the particulate additive and the edible paste extruded from the open end of the second small-diameter cylinder. This is a method for producing an edible paste containing additives.

  In the manufacturing method of the present invention configured as described above, the edible paste to which the particulate additive is added is introduced into the opening end of the first small-diameter cylinder, and a large number of the edible pastes are formed on the peripheral wall of the first small-diameter cylinder. An edible paste containing particulate additives is extruded from the small holes and is extruded into the cylindrical casing. At that time, the edible paste containing the particulate additive is extruded from a large number of small holes in the peripheral wall in various directions, and is mixed and dispersed by aggregating.

  Next, the edible paste containing particulate additives transferred between the casing and the first small-diameter cylinder and the second small-diameter cylinder is introduced into the small-diameter cylinder from a large number of small holes in the peripheral wall of the second small-diameter cylinder. The edible paste containing the particulate additive collected from various directions is mixed and discharged from the opening end to the downstream of the transfer pipe in a state where the mixing and dispersion further proceed.

  In the cylindrical casing, a second small-diameter cylinder separately provided with the same structure as the first small-diameter cylinder having a large number of small holes in the peripheral wall is arranged in the transfer pipe with the first small-diameter cylinder and the tip facing each other. By providing a simple manufacturing process in which the edible paste containing the particulate additive is forced through extrusion, the particulate additive and the edible paste can be efficiently and uniformly mixed and dispersed within a short distance line.

  And in the manufacturing method of the edible paste containing the particulate additive provided with the step of further finishing and mixing the edible paste containing the particulate additive taken out from the proximal end of the second small diameter cylinder, the finish mixing step is performed. By making the edible paste pass through an in-line mixer in which one or more rotating blades and one or more fixed porous disks are alternately arranged in the axial direction in the cylindrical casing, A mixture of edible pastes containing additives can be reliably homogenized.

  In this manufacturing method, as a structure of an inline mixer, one or more rotating moving blades are disposed in a cylindrical casing, and a porous disk is fixed between two moving blades, along the axial direction. Even if it is not completely mixed just by passing through the opposed two small-diameter cylinders, the rotating blades are arranged so that alternately rotating blades and fixed porous disks are arranged. Alternatively, the axial flow around the shaft acts together with the passage of the porous disk, that is, the shearing, mixing, and dividing steps are strongly performed multiple times, and the particulate additive is uniformly mixed and dispersed.

  As the particulate additive that can be mixed in a preferable state in the step of uniform mixing, vanilla beans, ground (so-called ground-down) apple fruit or mandarin orange has obtained favorable results. These may be used alone or in combination of two or more.

  Further, the in-line mixer used in the invention relating to the method for producing the particulate additive-containing edible paste has a diameter in which the distal end is closed and the large diameter portion of the proximal end is in close contact with the tubular casing in the tubular casing. In addition, a first small-diameter cylinder having a large number of small holes is provided on the peripheral wall, and a second small-diameter cylinder separately provided in the same structure as the first small-diameter cylinder is directed to the first small-diameter cylinder and the tips thereof in the cylindrical casing. It is preferable to adopt a structure in which they are arranged together.

  In the invention relating to the method for producing edible paste, the second small-diameter cylinder separately provided with the same structure as the first small-diameter cylinder having a large number of small holes in the peripheral wall is faced with the first small-diameter cylinder and the tips thereof in the cylindrical casing. By arranging and providing a simple manufacturing process of forcibly passing through this in-line mixer, it is possible to mix the particulate additive so that it is efficiently homogenized at a short distance as needed in the pipe for transferring food, Moreover, when producing continuously, there is an advantage of a method for producing an edible paste containing a particulate additive that can be produced under favorable conditions from the viewpoint of quality and hygiene.

  Moreover, in the invention provided with a step of further uniformly mixing the edible paste containing the particulate additive taken out from the proximal end of the second small-diameter cylinder as a step of the above manufacturing method, the above-mentioned advantages are more reliably achieved. Played.

  Further, in the invention relating to the in-line mixer of the present invention, solid particles are mixed so as to be efficiently homogenized over a short distance as needed in a pipe (line) for transferring an edible paste containing particulate additives. In addition, there is an advantage of being an in-line mixer that can be manufactured under favorable conditions in terms of quality and hygiene in the case of continuous production.

  Embodiments of a method for producing an edible paste containing the particulate additive of the present invention and an in-line mixer used therefor will be described below with reference to the accompanying drawings.

  As shown in FIGS. 1-3, the manufacturing method of the edible paste containing the particulate additive of embodiment uses the edible paste A, such as the flour paste prepared in the process outside a figure from the raw material containing a grain flour and fats and oils. Pressurize with a pump (rotary pump) and transfer, add particulate additive B such as vanilla beans from an automatic addition machine (not shown), then extrude the edible paste containing particulate additive from the first in-line mixer 1 In addition, the second in-line mixer 2 is used as a step for further homogeneous mixing, and the method for producing a particulate additive-containing edible paste comprising the step of passing the paste therethrough.

  As shown in FIG. 2, the first in-line mixer 1 described above is provided in the cylindrical casing 3, has a large number of small holes 4 in the peripheral wall, and has a flower inside the open end 6 of the first small-diameter cylinder 5. A high-viscosity edible paste such as a paste is introduced and the mixture is fed out. The first small-diameter cylinder 5 closes the downstream end portion 7 and opens the outer peripheral portion of the open end 6 facing the paste flow. The large-diameter portion 8 is closely attached to the inner peripheral surface of the cylindrical casing 3. The separately provided second small-diameter cylinder 9 has the same structure as the first small-diameter cylinder 5, and the first small-diameter cylinder 5 and the distal end portion 7 are arranged on the downstream side of the first small-diameter cylinder 5 in the cylindrical casing 3. They are arranged facing each other (see FIG. 1).

  The first in-line mixer 1 introduces an edible paste such as a flour paste flowing in a pipe into the first small-diameter cylinder 5 and extrudes the particulate additive and the edible paste outside the small hole 4, and supplies the second small-diameter to the second small-diameter. The structure is such that the edible paste containing particulate additives is introduced from the small holes 4 of the tube 9 into the inside and fed from the end of the second small-diameter tube 9, so that the edible paste flowing along the inner wall of the tube and the tube There is a function to mix well with the edible paste flowing near the center.

  The second in-line mixer 2 used in the next step is provided with propeller-like rotor blades 12 and 13 and a hub-like rotor blade 14 that are rotated by an external electric motor 11 in a cylindrical casing 10. A total of four perforated discs 15 are fixed at both ends.

  The edible paste used in the present invention does not refer to a particularly limited food or food raw material, and after food such as vegetables, meat, seafood, and fruits is in a raw state or heated, it may be ground or strained as necessary. In a general sense, what is prepared in a soft and smooth state without too much lump, the specific examples include fruit jam, koji koji, soybean koji, koji, chestnut koji, In addition to confectionery or bread fillings such as fruit spreads, fruit preparations, flower pastes, chocolate flower pastes, and butter creams, well-known pasty foods such as bread curry, pizza sauce, mayonnaise and rice cakes can be listed .

  In addition, as described above, the above-mentioned flour paste is a material that employs a material containing general cereal flour and fats and oils that are filled or applied to confectionery such as bread, pies or cream puffs and used for food. . A typical example of cereal flour is wheat flour, but rice flour, corn flour, etc. may be used, and fats and oils are added to these, and starch, nuts or processed products thereof, cocoa, chocolate, coffee, fruit juice, strawberries Pasta, beans or vegetables, sugar, powdered milk, eggs, etc., and pasteurized by heat sterilization.

  Particulate additives added to such flour pastes and other edible pastes include, for example, vanilla beans, ground apple fruit or tangerine “sano”, sesame seeds, poppy, cumin seeds and other fine particles. Examples include seeds, natural powdered flavors and flavors such as cinnamon and matcha tea, and powdered spices such as pepper powder, powdered pepper, and turmeric, and other solid substances. The particle size of such solid particles can be exemplified as a mixture of about 50 μm to 5 mm.

  Here, as shown in FIGS. 2 (a) and 2 (b), the first in-line mixer 1 is installed in a line with flanges 18 provided at both ends of the cylindrical casing 3. Is provided with a small-diameter portion (contact) 19 for locking the large-diameter portion 8, and the first small-diameter cylinder 5 and the second small-diameter cylinder (same structure as the first small-diameter cylinder are disposed in the opposite direction) 9 and 2. They are used as a pair and are liquid-tightly installed in a packing 20 inside the flange 18. Although the cylindrical casing 3 is illustrated in a cylindrical shape, a known cylindrical casing such as a polygonal cylindrical shape may be employed.

  The shape, number and arrangement of the small holes 4 formed in the peripheral walls of the first small diameter cylinder 5 and the second small diameter cylinder 9 are not particularly limited, and are particulate at a constant speed according to the fluidity of the edible paste. The hole shape, hole diameter, number of holes, and arrangement (intervals and rows) can be appropriately changed in design so that the additive can be easily added. In the illustrated embodiment, eight small holes 4 are formed in a row near the tip 7 of the first small-diameter cylinder 5 at equal intervals in the circumferential direction.

  The second in-line mixer 2 used in the finishing mixing process shown in FIGS. 1 and 3 includes a drive shaft 21 that is rotated by an external electric motor 11 in a cylindrical casing 10, propeller blades 12 and 13, and hub blades. 14 are attached in order from the tip, and a porous disk 15 is provided between and at both ends along the inner peripheral portion of the cylindrical casing 10 and screwed to the fixing ring. The shape and number of holes formed in the porous disk 15 are not particularly limited, and may be a well-known porous form in which circles, ellipses, ellipses, or polygons are arranged in one or more rows in the circumferential direction.

  In this way, the edible paste containing the particulate additive that passes from the tip opening 22 to the side opening 23 of the second in-line mixer 2 is caused to flow downstream in the axial direction by the propeller blades 12 and 13 and the hub blade 14. The edible paste is strongly sheared and then mixed or divided so as to disperse the particulate additive more uniformly because it passes through the flow and four porous disks 15 arranged between them.

  Although such an in-line mixer has a relatively simple structure, a small amount of particulate additive is efficiently mixed with the edible paste at a short distance, so that the possibility of solid particles remaining in the line is low. Therefore, it can be said that the particulate additive-containing edible paste can be produced from the viewpoint of quality and hygiene of the edible paste even when continuously mixed or when used after washing.
