(Prior art) Conventionally, methods for drying grains such as rice include drying the rice by exposing it to the sun after harvesting, or throwing it into a drying silo in the form of unhulled rice after threshing, and drying it in a high place. While dropping the unhulled rice one after another, at the same time hot air is blown upward from the bottom of the silo, the dropped unhulled rice is lifted up to a high place on a conveyor, and this dropping and lifting process is repeated several times until the dryness is uniform. I was letting it happen.

(Problems to be solved by the invention) However, in the conventional method of exposing rice to the sun,
There was also the problem that it took a long time due to rain or bad weather. In addition, the method of drying the unhulled rice in a drying silo involves dropping the unhulled rice from a high place, which creates a lot of noise and dust, and because it is dried with hot air, the outer part of the rice dries quickly, and there is still moisture in the core. If any residue remains, the rice will crack later on, and the rice will taste bad because it is heated and dried.
Another problem is that it cannot be stored for a long time. Additionally, there was a problem in that the equipment was large-scale and expensive.

(Means for Solving the Problems) The present invention was made to solve these conventional problems, and its purpose is to dry the grains with dry air while leaving the grains stationary without moving them. As a technical means to achieve this objective, the grain drying method of the present invention uses a heating condenser, a cooler, An air circulation system path is formed in which the air passes through the heating condenser in order and is supplied to the drying chamber again, and when the temperature is lower than the set temperature by the thermostat installed in the drying chamber, both the heating condensers and the cooler are operated to dry the air. High-temperature, low-humidity air is supplied into the drying room, and if the temperature is higher than the set temperature by the thermostat, both heating condensers are stopped and only the cooler is operated to supply low-temperature, low-humidity air into the drying chamber, and the heating condenser is activated. Expanded air generated due to temperature rise due to the supply of high-temperature, low-humidity air is exhausted to the atmosphere through a one-way valve, and the grains are stored in a pile in the drying chamber. (We decided to adopt a method of drying the grain by blowing air from the container room.

(Function) Therefore, according to the method of the present invention, low-temperature and humid air from the drying chamber is first passed through a condenser in a refrigeration cycle and heated to become hot and humid air, and then this is passed through a cooler to dehumidify it. The basic drying method is to turn the air into low-temperature, low-humidity air, which is then passed through a condenser and heated to become high-temperature, low-humidity air, and then blows this high-temperature, low-humidity air into the interior of the grains deposited in the drying chamber. (Since the expanded air generated by the temperature rise caused by supplying humid air is exhausted to the atmosphere, it prevents a pressure increase in the drying chamber and maintains the inside of the drying chamber at atmospheric pressure when supplying high temperature, low humidity air, and the next When low-temperature, low-humidity air is supplied, the air inside the drying chamber contracts and the pressure inside the drying chamber is reduced, so the inside of the drying chamber is always maintained at below atmospheric pressure, and the synergy between drying under this reduced pressure and drying using high-temperature, low-humidity air is achieved. This action allows for effective drying.

Then, when the compressor 31 of the dehumidifier 816 is operated and operated in a refrigeration cycle of compressor 31 → heating condensers 32, 33 → cooler 37 → compressor 31, and the forced air blower 8 is operated. The low-temperature and humid air containing moisture in the drying chamber 5LB flows into the equipment room, where it is first heated by the heating condenser 32 to become hot and humid air, and then cooled by the cooler 37. ,
The air becomes dehumidified, low temperature and low humidity. In this case, the cooler 37
Since the air passing through is heated by the front heating condenser 32, there is a large temperature difference from the cooling temperature by the cooler 37, which makes it possible to effectively dehumidify while making full use of the cooling function of the cooler 37. In other words, it will be possible to Then, the air that has passed through the cooler 37 and has become low temperature and low humidity is heated again by the heating condenser 33 and becomes high temperature and low humidity air 1), and this high temperature and low humidity air passes through the ventilation duct 7 and the ventilation pipe 5. The water is ejected from the small hole 14 of the ventilation pipe 5, passes through every gap in the accumulated unhulled rice, and at this time deprives the unhulled rice of moisture. After absorbing water, 1
The air becomes hot and humid and passes through the small hole 14 of the exhaust pipe 4 to the exhaust pipe 4.
or directly into the space 3 through the mesh of the wire mesh wall 2 of the deposition chamber C, passes through the air intake 9a from the air inlet 9a of the exhaust duct 9, and passes through the dust filter 10.
After dust and dust are removed, the air becomes clean air, passes through the dehumidifier 6 again, where it becomes high-temperature, low-humidity air, and circulates through the ventilation system 7 in the same manner as described above.

, 43 is switched 1), and thereafter the heating condenser 32.33
Drying is carried out by repeatedly supplying high-temperature, low-humidity air by operating the heating condensers 32 and 33, and supplying low-temperature, low-humidity air by stopping the heating condensers 32 and 33.

Furthermore, when the aforementioned heating condensers 32 and 33 are in operation, high-temperature, low-humidity air is supplied, so the air expands as the temperature of the drying chamber B rises, and this expanded air causes the inside of the drying chamber B to expand. Although the pressure tends to be higher than atmospheric pressure, this expanded air is exhausted to the atmosphere via the check valve 46, so the pressure inside the drying chamber B is maintained at atmospheric pressure. This means that if the check valve 46 is not provided, the pressure will be higher than atmospheric pressure, so the pressure is reduced compared to this case. Then, when low-temperature, low-humidity air is supplied by switching the thermostat 45, the air contracts as the temperature of the drying chamber B decreases, and as a result, the inside of the drying chamber B closes to the check valve. From the atmospheric pressure state obtained by 46: the drying chamber B is constantly maintained below atmospheric pressure.

(Effects of the Invention) As explained above, according to the method of the present invention, since heating condensers are disposed before and after the cooler, the air passing through the cooler becomes preheated high-temperature and humid air, and is cooled. A sufficient dehumidification effect can be obtained due to the large temperature difference, and since this air is reheated and supplied to the deposition chamber as high-temperature, low-humidity air, an even greater drying effect can be obtained. Furthermore, the inside of the drying chamber can be maintained at below atmospheric pressure by simple means,
Compared to the conventional method, drying is performed under reduced pressure, and extremely effective drying can be performed.
