Description

[Detailed explanation of the idea] The present invention relates to an air conditioning device most suitable for a rice milling machine.

Generally, in a rice milling machine, supplying appropriately adjusted low-temperature, humid air to the milling chamber of the rice milling machine promotes the peeling of the bran layer of brown rice and suppresses the rise in rice temperature caused by milling, which improves the rice milling process. This makes it possible to mill rice without losing its enzymatic activity.

By the way, in conventional rice milling machines, supply air is simply used after being humidified either directly from inside or outside the rice milling plant or by passing it through a cold water pit.

Therefore, the temperature and humidity of the supplied air is not adjusted at all, and even if it passes through a cold water pit, it is affected by the seasonal atmospheric temperature and humidity, making it impossible to mill white rice of a constant quality throughout the year. It was extremely difficult.

This invention was made in view of the above-mentioned conventional problems.
To provide a new air conditioning device for a rice milling machine which easily and accurately adjusts the air supplied to the rice milling machine to suitably low temperature and humid air in advance.

Therefore, the present invention basically includes a closed container-shaped housing having a water tank at the bottom, a water spray nozzle at the upper part of the housing, and an external air intake port for the housing. The present invention is characterized in that it is provided with a regulated air outlet for sending regulated air to the rice milling machine, and also provided with an adjusting means for adjusting the temperature of the water sprinkled, the amount of water sprinkled, and the amount of external air.

When the water temperature in the water tank is high, a cooler 31 is used, and when the water temperature is low, a heater 32 is used to keep the water temperature constant.

Note that when underground water is used for cooling, the water temperature is constant, so the cooler 31 and heater 32 are not necessary.
The water in the water tank 15 may be drained from the drain port 17.

Further, even when adjusting only the humidity, the cooler 31 and heater 32 are not necessary, and it is sufficient to simply replace the water in the ice tank 15 at an appropriate time.

Since it is equipped with a means, water is sprinkled from the water nozzle inside the housing, the temperature and humidity of the external air taken in from the external air intake are adjusted, and this adjusted air is supplied to the rice milling machine from the adjusted air intake. It is possible to constantly supply humid air at a temperature lower than the rice temperature during milling or polishing to the milling chamber of the rice milling machine, thereby promoting the separation of the bran layer of brown rice and suppressing the rise in rice temperature due to milling. This makes rice milling work more efficient and allows rice to be milled without losing its enzymatic activity.

In addition, the structure is extremely simple, there are few failures, and it is possible to constantly and stably supply conditioned air to the rice milling machine.
