Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a humidifying rice polishing apparatus particularly suitable for polishing sake-brewing rice.

Generally, in the polishing action of a rice milling device, the temperature of the grains increases several degrees each time the rice grains pass through the milling chamber, thereby drying the rice grains.

In particular, in the polishing of sake-brewing rice, repeated circulatory stacking is carried out until the yield rate is extremely low, which generates a lot of heat and causes the rice grains to dry out, which reduces the efficiency of the polishing process. As the load changes, broken rice frequently occurs due to drying.
Furthermore, in order to prevent underwater cracking during soaking, it takes a long time to process the mustard after rice milling.

The present invention solves the above-mentioned drawbacks.The present invention aims to eliminate the above-mentioned drawbacks by adding mist moisture to the rice grains flowing down through the upper void chamber in the grain tank installed at the front stage of the rice milling machine in the grain circulation stage of the rice milling equipment. In addition to moistening and softening only the thin layer of the rice grains, the suction force of the exhaust fan absorbs and eliminates the grain temperature while the rice grains flow in the lower tempering chamber, thereby preventing moisture spots, etc., and milling. In addition to improving the milling efficiency by efficiently polishing the surface of rice grains that have been softened by moisture, it also prevents the grain temperature of polished rice from rising and moisture evaporation, eliminating the need for the above-mentioned mustard time and completely eliminating the occurrence of crushed grains. The purpose of the present invention is to develop and provide a high-performance humidifying rice milling device that prevents the grain surface from drying out and ensures high-quality milled rice at an appropriate temperature using an appropriate amount of water absorbed from the surface of the grains.

The present invention will be explained with reference to embodiment figures. A rice milling machine 4 with a milling chamber 3 equipped with a vertical rotary grinding rotor 2 mounted on the top of a base 1.
A humidifying grain tank 6 is placed on the supply port 5 of the rice miller 4.
At the same time, an elevator 7 is erected on the side of the base 1 to form an integrated rice milling device. Grain flow lower passage 9・

are connected by a flow tube 16, and the grain circulation process passing through the whitening chamber 3 is integrally formed.

The grain tank 6 is divided into an upper cavity 17 and a lower tempering chamber 18.
The upper cavity 17 is provided with a plurality of moist air ports 19 for humidifying the rice grains flowing down from each grain flow path 9 of the supply screw conveyor 10. 19... and a moist air generator 20 provided on the side of the grain tank 6 are connected by an air supply pipe 21, and the lower tempering chamber 18 has a plurality of ventilation passages 22 and 20 inside. ... is installed, and each common flow path 22 ... is mounted thereon.

The humid air generating device 20 is provided with a fog generator 25 consisting of a nebulizer and a cooling device 26 consisting of a cooler in the middle of the air supply pipe 21 connected to each of the humid air ports 19, and a cooling device 26 consisting of a cooler. The blower 27 is connected, and 28 is the blower 2.
Reference numeral 7 is a picture style on-off valve, 29 is a humidity sensor provided in the exhaust pipe 24, 30 is a moisture meter provided in the grain tank 6, 31 is a thermometer provided in the grain tank 6, 32 is a humidity sensor 29, picture style Humidifier J is electrically connected to the on-off valve 28, the moisture meter 30, and the thermometer 31 to adjust the temperature, humidity, and air volume of the humid air.
! This is a control device for 1lli clauses. Note that the ventilation flow path 2
2 has two plate bodies formed in a mountain shape to form an air passage inside, and a ventilation flow passage 22A shown in FIG. These are J4 joints that are connected to form a large air passage.

In addition, the humidification effect of the present invention is intended to prevent the moisture content of rice grains from being derived during the polishing process, so it is fundamentally different from general grain tempering treatment that aims to increase the moisture content of rice grains. The gist is different.

With the above-mentioned configuration, when raw brown rice is put into the lower supply port 15 of the elevator 117 and the device is started, the brown rice is fried and flows into the supply squeezing conveyor 10 at the upper part of the grain tank 6, and the gutter The grains flow down into the upper cavity 17 in equal parts from each grain flow path 9 provided in the bottom part 8. During this time, the mist moisture generated by the fog generator 25 of the humid air generator ff20 is turned into damp air by the wind of the blower 27, and is ejected from each humid air outlet 19 through the air supply pipe 21.
Atomized water is added to each flux of rice grains flowing down in the void 17 to moisten and soften only the thin layer on the surface of the grains, and each rice grain accumulates in the lower tempering chamber 18 to form grains. The grain layer is formed in the tempering chamber 18 while the grain layer flows downward.
The grain temperature of each rice grain is collected by the air sucked from each ventilation channel 22 provided inside the machine, and is removed to the outside of the machine via an air exhaust device 23. Then, the rice grains whose surface has been moistened and softened, and whose grain temperature has been lowered to eliminate moisture spots, flow into the polishing chamber 3 and are polished by the rotation of the grinding trochanter 2, and the rice grains are removed from the discharge port 14. The grain flows down to the lower supply port 15 of the elevator 117, and is also fried by the elevator 7 and sent to the screw conveyor 1.
At the same time, the grains flow into the grain tank 6 through the grain flow paths 9 provided on the screw conveyor 10, and are again subjected to the humidifying action and heat removal action described above, and then flow into the milling room 3. and is ejaculated. Therefore, the whitening action in the whitening room 3 is carried out extremely efficiently and smoothly without causing the rice grains to dry out or break up due to changes in the load as described above, and the rice grains undergo the grain circulation process several times. It is polished to a predetermined level of polishing, taken out of the machine, and sent to the next process.

According to claim (3), the damp air generating device 20 is equipped with a damp air regulating control device 32 that adjusts the temperature, humidity, and air volume of the damp air, so that the damp air exhaust device is 23
When the IC humidity sensor 29 installed in the exhaust pipe 24 detects the exhaust air humidity and lowers the reference humidity (described later), the amount of water absorbed by the fog generator 25 is increased, and the on-off valve 28 of the blower 27 is adjusted. Immediately correct the humidity and air volume supplied by
In addition, when the thermometer 31 installed in the grain tank 6 detects the grain temperature and the temperature rises above the reference grain temperature (35°C to 15°C), the cooling device 26 is adjusted and cooled air is sent to immediately correct the grain temperature. The water content of the rice grains is moderately corrected to completely prevent the occurrence of split grains, and the grain temperature is moderately corrected to improve the water absorbency of the rice grains, making it possible to easily adsorb and replenish the insufficient water content of the rice grains.
