Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in a rice polishing machine for sake brewing and a rice polishing method for sake brewing.

In general, polished rice for sake brewing becomes hard, so it is only possible to polish it by grinding. In particular, when high-whiteness milled rice is produced with a yield of 80% or less, the milling efficiency is drastically reduced due to the grinding action, and a large amount of energy consumption cannot be avoided. As a countermeasure to this problem, a technology has already been published in which water is added to the dense layer of rice grains flowing through the gap between the polishing cylinder and the grinding trochanter in the milling room. Starch becomes viscous and sticks to the surface of the rice grains, resulting in uneven moisture spots and the adhesion of excess moisture, which actually hinders milling, and adding moisture to high-level milling is harmful and useless, so in fact, water is removed. There are no examples using this method.

Therefore, the present invention was developed in order to rationally add water to the hardened skin layer of polished rice to safely soften the surface of polished rice and to streamline high-level polishing of polished rice.

The present invention has a water addition type in a vacant chamber, which disperses an appropriate amount of water in the form of a mist of fine particles onto the top surface of the rice grain bed that revolves and flows in a vortex, and mixes the water well to achieve even and moderate grain surface humidification. After polishing, the humidified rice grains flow into the polishing chamber in the gap between the polishing cylinder and the grinding trochanter, and the softened rice grain surface is ground to prevent it from becoming viscous, making it possible to improve the efficiency of milling of hard polished rice, which is considered to be of low efficiency. can.

It is impossible to uniformly add water to the whole grain surface inside the dense flow-like rice grain layer in the rice mill as in the past. There is no other way to add ultra-precise, uniform, and appropriate amounts of moisture to the entire surface of the rice grains than by spraying fine mist moisture over the entire surface layer of the rice grain layer over a wide area exposed in a large empty space.

As mentioned above, the present invention makes it possible to add moisture suitable for high whiteness rice milling, which had been abandoned in the past, by precisely controlling the appropriate amount of moisture in the fine particles and spraying the particles evenly over the entire surface. The effect on improving whitening efficiency is remarkable.

The present invention will be explained with reference to embodiment figures. A rice polishing machine for sake brewing is formed by incorporating a grinding and polishing trochanter 2 mounted on a vertical shaft 1 into a polishing cylinder 3. A fog generator 9 is provided, which is provided with a vacant chamber 7 formed by the top M6, and which is separately composed of an ultrasonic vibration element 8.
and the air blower 110 are combined to form the mist moisture generating device 11, and the moisture generating device 11 and the air supply port 12 provided in the ceiling N6 are connected by the blower 13, and the rice grains passing through the empty chamber 7 are sprayed with mist. It is formed in a mist water addition chamber 14 for adding water in the form of water, 15 is a rice feed port, 16 is a rice discharge port, 17 is a whitening room, 1
8 is a water tank for supplying water to the moisture generating device 11, 19 is a water flow control valve, A is the upper surface of the polished rice layer formed in the polishing cylinder, and the atomized moisture addition chamber 14 is formed above the upper surface. Ru.

With the above-mentioned configuration, the rice grains flowing down from the rice supply port 15 into the empty chamber 7 have an appropriate amount of atomized moisture generated by the neolyzer from the air supply port 12 on the upper surface of the rice grain layer that revolves around the room in a whirlpool. After being dispersed and sufficiently mixed to properly humidify the grain surface without unevenness, it flows into the polishing chamber 17 in the gap between the polishing cylinder 3 and the grinding polishing trochanter 2, and is softened so as not to become viscous. Since rice grains are milled by grinding the surface, as mentioned above, by precisely controlling the appropriate amount of moisture in the grains and spraying the grains evenly over the entire surface, it is possible to achieve moisture levels suitable for high whiteness milling, which had previously been abandoned. In addition to making addition possible, the effect on improving the milling rate is remarkable due to the high-efficiency milling action.
