Description

  The present invention relates to a washing-free rice production apparatus for testing. Specifically, when washing grains such as rice and wheat as a raw material without washing, the testing-free rice can be processed before actual operation. The present invention relates to a washing machine.

  Conventionally, when cereals such as rice and wheat are milled, it is necessary to know the properties of the raw rice in advance and to determine the kneading accuracy and flow rate setting during the milling before starting continuous milling. Is called. In other words, depending on the raw rice, the difficulty of milling differs depending on the moisture and varieties, so the raw rice sample is collected in advance, supplied to a test rice mill, etc. After that, it is performed to determine the rice bran accuracy and flow rate setting at the time of milling so as to achieve a predetermined milling degree and yield.

  For example, Patent Document 1 discloses a small rice mill that can be used as a rice mill for testing, and this small rice mill is provided with a milling degree measuring device and a collecting device so that accurate milling is always performed. The degree and yield can be measured.

  In addition to this, as to the processing of cereals, the test rice hull refiner of Patent Document 2, the grain test dryer of Patent Document 3, and the taste test rice mill of Patent Document 4 are known as test machines.

  By the way, by removing the Aleurone layer (glue layer) adhering to the rice after whitening with a rice mill, so-called no-wash rice that does not require water sharpening during cooking has been attracting attention year by year. Production is increasing. In particular, the method of removing the aleurone layer (glue layer) using the adhesive force of tapioca pearl has attracted attention because it greatly reduces the amount of water used in the rice mill. Patent Document 5 discloses a processing method for removing the aleurone layer (paste powder layer) using the adhesive force of this tapioca pearl. This method mixes and stirs a process of adding moisture to milled cereal to soften the surface, and the milled cereal and a granule prepared to a particle size of 1.0 mm to 1.7 mm and heated to 60 ° C or higher. And a step of adsorbing and removing the wrinkles remaining on the grain surface of the refined cereal to the granular material, and a step of separating the refined cereal from the granular material.

  However, there is no testing machine to date in the above washing-free rice processing. That is, in the washing-free rice processing method using the tapioca pearl adhesive force, since a plurality of processes such as a water addition process, a mixing and stirring process, and a separation process are combined, it is difficult to configure with a single machine. It is speculated that there was. For this reason, for example, if the annual production, varieties (difference between short and long varieties, etc.), production area, etc. of raw cereals used as raw materials are different, the washing-free rice production equipment will be fully operational each time with the minimum processing amount The current situation is that some 500 kg of raw cereals are used for testing.

  Here, the configuration of the two processing containers 6 and 7 described above will be described with reference to FIGS. 2, 6, and 7. FIG. 6 is an enlarged perspective view of a non-porous processing container for adding water to the treated grain and for mixing the treated grain and the adsorbent, and FIG. 7 shows the treated grain and the adsorbent. It is an expansion perspective view of the perforated processing container for isolation | separation of an adsorbent from the mixture of these. The perforated processing container 7 shown in FIG. 7 is provided with a number of slit holes 32 on the side wall of the container, but the non-perforated processing container 6 shown in FIG. 6 is provided with slit holes 32. Not. This is a major difference between the two processing containers 6 and 7. The slit holes 32 are used as sieves for sieving the adsorbent. For example, when tapioca is used as the adsorbent, the particle diameter is 0.8 mm to 1.7 mm. Since it is prepared, it is preferable to set the width of the slit holes 32 to 1.7 mm and the length to 25 mm. Accordingly, the size of general polished rice is about 5.5 mm to 9.5 mm in length, about 2.2 mm to 3.0 mm in width, and about 1.9 mm to 2.3 mm in thickness. There is no risk of leakage, and it will be clearly separated and distinguished from tapioca. In addition, as the adsorbent, those derived from rice, such as those in which the grain size of pulverized rice is uniformed or those in which the grain size is dried by alpha-izing the rice can be used.

  The processing containers 6 and 7 have an inverted conical mortar shape to remove polished rice having an amount of about 1 kg as a processed grain and an aleurone layer (glue layer) adhering to the processed grain. It is good to form in the external dimension which can accommodate substantially the same amount of adsorbent as the to-be-processed grain. In the present embodiment, for example, an inverted conical mortar shape having a bottom diameter of 90 mm and an opening diameter of 172 mm is used.

  At the center of the bottom of these processing containers 6 and 7, the rotary shaft 15 is provided in a vertically penetrating manner, and a stirring blade 14 is provided at the upper end. The stirring blade 14 stirs the treated grain to which moisture has been added to make the moisture uniform, mix and agitate the treated grain and the adsorbent, and the adsorbent and the treated grain. There is an action which gives centrifugal force.

  The stirring blade 14 is configured in a shape that takes into account the stirring ability of the grain to be processed. That is, the peeling action (friction milling action) of the grain skin due to grain friction between the treated grains and the cutting action (grinding milling action) of the grain skin due to the stirring force of the stirring blade 14 are difficult to occur. It has a shape. That is, as shown in FIGS. 6 to 8, the stirring blade 14 has a vertical axis 14a fitted to the rotary shaft 15 and a horizontal direction from the base portion 14b of the vertical axis 14a toward the processing containers 6 and 7. A protruding portion 14c that protrudes, an inclined portion 14d having a similar shape extending from the protruding portion 14c along the mortar-shaped inclined surface of the processing containers 6 and 7, and an inclined intermediate portion of the inclined portion 14d toward the longitudinal axis 14a And a cruciform stirring portion 14e provided. Furthermore, if the rotation speed of the stirring blade 14 is suppressed, the rice milling action is difficult to occur.

  The above-described stirring blade 14 (see FIG. 8) can reduce the peeling action and cutting action of the grain skin, but also causes problems such as longer stirring time (stirring action). Therefore, a shape in which the cross-shaped stirring portion 14e is omitted as shown in FIG.

  Next, the operation of the test washing-free rice producing apparatus of the present embodiment will be described with reference to the flowcharts of FIGS.

It is rotated and stirred, and centrifugal force is applied to the processed grain and the adsorbent. And since the adsorbent has a small particle size of 1.0 mm to 1.7 mm, the adsorbent leaks out from the slit holes 32 formed in the processing container 7 and is recovered in the adsorbent recovery container 5, while the processed grain is Since the size is about 5.5 mm to 9.5 mm in length, 2.2 mm to 3.0 mm in width, and about 1.9 mm to 2.3 mm in thickness, the size remains in the processing container 7. That is, the selection based on the particle size of the processed grain and the adsorbent, that is, the separation step of separating the processed grain and the adsorbent is performed through the slit holes 32 provided in the processing container 7. (Step S19).

  When the rotation by the stirring blade 14 elapses for a predetermined time and the separation process is completed, the blinking display of the separation [1] button 13d is switched to the lighting display as a process for informing the end (step S20), and the motor 8 is temporarily driven. Stop (step S21). At this time, the operator opens the opening / closing lid 3, takes out the processing container 7 from the main body 2, sets the processing container 6 in the main body 2 again, and transfers the processed grains in the processing container 7 to the processing container 6. Operate (step S22).

Tapioca 500 [g] is added so that tapioca is 50% by weight with respect to 1 [kg] of polished rice (step S12), and the particle size at room temperature is 0.8 mm for drying or moisture conditioning of the treated grain. Tapioca 500 [g] is added to tapioca in the range of ~ 1.7 mm to 50% by weight with respect to 1 [kg] of polished rice (step S25). Got.

  As a conventional example, it was processed into non-washed rice by a non-washing rice production apparatus installed in a large rice mill. Particle size heated to 60-100 ° C with 0.167 [ton / hr] of water added to 3.7 wt% with respect to the flow rate of 4.5 [ton / hr] of polished rice as raw material (raw material) Add tapioca in the range of 1.0mm to 1.7mm, mix and agitate to adsorb the aleurone layer (glue layer) adhering to the rice grain surface to tapioca side, then separate tapioca and rice Unwashed rice was obtained.

  The quality of each of Example 1, Example 2, Example 3, Example 4, Conventional Example and raw materials was analyzed. The results are shown in Table 1. The turbidity was measured by the following method.

Turbidity was calculated | required by the measured value of the turbidimeter of the washing | cleaning waste water obtained by stirring sample rice with water. As an example, 20 g of sample rice is put into an Erlenmeyer flask, 200 ml of water is poured, a rubber stopper is put on, and shaken for 10 minutes with a shaker (model SA-31A manufactured by Yamato Scientific Co., Ltd.) (144-150 cycles / And 50 ml of the resulting washed rice waste water is diluted 10 times and measured three times with a turbidimeter (Noda Communications Model M-204, etc.). The average value was defined as turbidity.

  As shown in Table 1, when referring to moisture, the moisture content in Examples 1 to 4 is slightly higher than 0.7% to 0.8% compared to 14.5% of the raw material and 14.3% of the conventional example. Value. It can be said that drying or moisture conditioning by mixing and stirring the adsorbent has been successful.

  Further, in terms of whiteness, it was found that Examples 1 to 4 showed almost the same value as the conventional example. Moreover, it turns out that the whiteness with respect to a raw material exceeds about 5 to 7% of the direction of Example 1 thru | or Example 4, and even if it is a simple apparatus, the aleurone layer (paste powder layer) was removed. Succeeded in producing washed rice.

  In terms of volumetric weight, Examples 1 to 4 are slightly higher than the conventional example. In addition, referring to the water-immersed split grains, it was found that Examples 1 to 4 showed almost the same values as the conventional example.

  Referring to the body split grains, Examples 1 to 4 tended to have a higher ratio of body splits than the conventional examples.

  In terms of turbidity, Examples 1 to 4 tended to have lower turbidity than the conventional example. This is probably because the aleurone layer (glue layer) adhering to the rice was removed again in the adsorbent mixing and stirring step for drying the treated grain or moisture conditioning. However, by finely adjusting the addition ratio of water to the raw material grain and its stirring time, the addition ratio of the adsorbent to the raw material grain and its stirring time, the stirring time when separating the raw material grain and the adsorbent, etc. The turbidity can be controlled to the same level as in the conventional example.

  As described above, it was confirmed that the non-washed rice prepared in Examples 1 to 4 could be finished to a quality almost equivalent to the non-washed rice prepared in the conventional example.

  Thereby, using the raw material grain of an amount of only about 1 kg, for example, the addition ratio of water to the raw material grain and its stirring time, the adding ratio of the adsorbent to the raw material grain and its stirring time, the raw material grain and The stirring time for separating the adsorbent and the like can be known for each property of the raw material. And when full-scale operation of the large washing-free rice production equipment installed in the rice mill, the ratio of water to the raw material grain and its stirring time, and the raw material grain so as to have a predetermined whiteness and turbidity It is possible to determine the optimum processing conditions such as the adsorbent addition ratio and the stirring time, and the stirring time when separating the raw material grains and the adsorbent, thereby improving the quality of the non-washed rice.

  When a large washing-free rice production device installed in a rice mill is fully operational by providing a washing-free rice production device for testing that can produce washing-free rice using only 1 kg of raw material grain The ratio of water to the raw material grain and its stirring time, the ratio of the adsorbent to the raw material grain and its stirring time, and the stirring time when separating the raw material grain and the adsorbent, etc. The processing conditions can be determined to improve the quality of non-washed rice.
