Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice polishing and humidity control device for improving rice polishing and humidity control effects for sake brewing.

Generally, rice for sake brewing involves high polishing with a polishing level of 75-50%, so the rice grains must pass through the milling chamber dozens of times, increasing the grain temperature each time the rice grains are subjected to the polishing action in the milling chamber. It was something to do. An increase in the temperature of the rice grains causes blocking of the rice grains flowing down from the tank into the milling room at the tank funnel, and also causes instability in the flow of rice grains in the milling room, leading to a motor stoppage accident.

Therefore, a ventilation fan is connected to a rice bran collection gutter that surrounds the lower part of Mangoku, which has a slanted sorting screen, and allows the rice grains flowing out of the milling room to slide onto the sorting screen, allowing the separated rice grains to fall down and to be discharged. The suction action of the wind machine was used to circulate air through the rice grain layer to cool the rice grains, and the rice bran sucked into the exhaust fan was air-transported to the appropriate location, but in this case, air was circulated through the rice grains whose temperature had risen. Therefore, the ventilation effect dries the rice grains and causes cracks, so the rice is milled to the desired degree of polishing in order to operate the milling chamber at a low load and suppress the rise in rice temperature as much as possible. It took a long time to do so.

In order to improve the above problems, a vertical grinding type grain milling machine is placed above the rice bran sieve mangoku, and a rice polishing tank is connected to the funnel stand of the vertical shaft grinding type grain milling machine. Japanese Patent Application Publication No. 2006-110010 discloses a brewing rice milling device which is equipped with an air cooling duct to cover the discharge port of the vertical grinding grain milling machine, and an air humidifying device is provided in the air cooling inlet of the air cooling duct. 1972-
This product, known as Publication No. 85344, supplements the humidity of the air vented to the polished rice to cool the polished rice, thereby preventing cracks caused by drying, stabilizing the load in the milling room, and achieving highly efficient milling. However, even if moist air with saturated humidity is used, the effect of the cold, moist air is only during the short period when the rice grains flow out of the milling room and slide over the top of the rice grains. Due to the exothermic action that causes the temperature to rise each time the rice is subjected to the whitening process in the milling room, it is not possible to maintain the drying moisture by supplementing the moisture value of the brown rice that was retained at the start of operation, and when the rice is immersed in water after milling is completed, This left the problem of not being able to prevent the occurrence of cracks unresolved.

Based on the actual situation explained above, it takes several weeks to a month to store polished rice in a product tank and naturally radiate heat, as well as to make the indoor atmosphere highly humid and return water to the polished rice (commonly known as drying treatment). It was necessary.

In addition, when tempering polished rice to a safe moisture content (14.5 to 15%) that does not cause underwater cracks when immersed in water, humidification must be done at a rate that is within the water absorption rate of polished rice, otherwise the humidification effect part of the polished rice will This causes distortion and cracks in the inner layer of polished rice, so in order to humidify the polished rice to a moisture content that is safe for soaking, it is necessary to set up a large-scale tempering room and humidity conditioning time, which reduces equipment costs. There are problems in that it is expensive and requires a large installation area, and there is a pressing need for improvement of the above problems.

The present invention will be explained below based on embodiment figures.

A hot air generator 5 is connected via an air path to a humidifying chamber 2 having a plurality of umbrella veins therein, and a ventilation cooling device 4 is attached to the air path to form a cold/humidifier 3. . The cold/humidifier 3 is installed in the front stage of the rice polishing machine 1, and the humidity controller 6 equipped with a hot air generator is installed in the rear stage of the rice polishing machine 1. and the humidity control machine 6 are connected in series through channels, and the rice grain discharge channel of the humidity control machine 6 is connected to the supply port 9 of the rice lifter 7, and the upper part of the rice lifter 7 is cooled and humidified. It is connected to the supply section 8 of the machine 3 and is formed in the circulation path of rice grains.

Since the configuration is as described above, brown rice is supplied from the supply port 9 of the rice frying machine 7 to the cold and humid chamber 3, and the brown rice that has been cooled and humidified in the cold and humid chamber 3 is transferred to the rice milling machine 1 and polished. Transfer the polished rice to humidity control machine 6 and rice polishing machine 1.
Replenish dry moisture with. The white rice that has been humidified by supplementing moisture is returned to the cold-humidifier 3 by the rice lifter 7, and the white rice is cooled and humidified. Thereafter, the polished rice is passed through the rice polishing machine 1 and the humidity controller 6, and then returned to the cold humidity chamber 3. It is circulated multiple times to impart various effects to the polished rice, and the polished rice is humidified at a low temperature to the desired degree of polishing and moisture content. Processed into rice.

As explained above, according to the present invention, since a cooling machine and a humidifier are provided in the circulating rice milling process, the polished rice to be supplied to the rice milling machine is cooled, and the rice is humidified in the humidifier every time it passes through the rice milling machine. Therefore, at the end of the rice milling operation, the rice is processed to a safe moisture content and rice temperature before soaking.
This method simplifies the wasteful work of using a large-scale humidifier to humidify rice for a long time after rice milling as in the conventional method, reduces equipment costs, and significantly reduces the installation space of the equipment. The effect is remarkable.
