Abstract

PURPOSE:To smoothly moisten rice by calculating the amt. of water increased from data on the water content of the rice and the humidity of the atmosphere in a moistening chamber in accordance with an equilibrium water content diagram and by regulating the humidity of the atmosphere. CONSTITUTION:The water content of rice is measured with a water content analyzer 2 and the humidity of the atmosphere in a moistening chamber or apparatus 1 with a hygrometer 3. For example, 14% water content of rice equilibrates 67% relative humidity of the atmosphere in an equilibrium water content diagram. When 13% water content of rice is increased to 14%, the humidity of the atmosphere in the apparatus 1 is regulated to 67% and the rice is moistened while maintaining 67% humidity with a humidifier 5. This humidifier 5 is automatically controlled with CPU 4 so as to feed water required to maintain the prescribed humidity into the apparatus 1.

Description

[Detailed description of the invention] (Industrial application field) The present invention mainly relates to a method for humidifying rice grains.

(Prior art) Grain is dried using a grain drying device, and then hulled and
Performs adjustment processing such as rice polishing and stone removal. It remains highly hydrated;
This is because even if the rice is hulled, good results will not be obtained. Note that if the dryer is too dry and the material is overdry, perform the adjustment process after humidifying the material in the opposite manner to the above. If drying in the dryer fails, the moisture content exceeds the specified moisture level of 14.5%,
Overdrying can occur by up to 13%.

Such dry rice is humidified using a humidifier to restore moisture.

The present invention has been made to provide a better method for the above-mentioned humidification method.

(Problems to be Solved by the Invention) Conventional humidifying devices simply humidify without considering the atmospheric humidity of the humidifying chamber or humidifier.
It was not possible to smoothly perform quantitative humidification.

(Unfortunate to solve the problem) Therefore, the present invention obtains grain moisture value data using a grain moisture meter, obtains atmospheric humidity data using a hygrometer, obtains the desired moisture increase amount from an equilibrium moisture value graph, and performs humidification. This is a rice grain adding method that automatically controls a device to maintain a humidifying chamber or a humidifier at an atmospheric humidity of a desired moisture content to humidify rice grains.

(Example) l is indoors or inside a humidifier, 2 is a grain moisture meter, 3 is a hygrometer,
4 is a CPU, and 5 is a humidifier.

According to Figure 2, the relative humidity of the atmosphere when the grain moisture is 14% is 67%, so in order to humidify the grain with a moisture value of 13% to a moisture value of 14%, the atmospheric humidity must be adjusted to 67%, and the humidity in the humidifying chamber must be adjusted. Or use a humidifier.The atmospheric humidity of moisture is 67%.
It is a good idea to keep the rice at a constant temperature and humidify the rice grains. That is, C
The PU 4 automatically controls the humidifying device 5 and supplies moisture to the atmosphere of the humidifying chamber or humidifier with moisture that makes the atmospheric humidity 67% (effect). Humidify the rice by determining atmospheric humidity data using a hygrometer, determining the desired amount of moisture increase from the equilibrium moisture value graph, and automatically controlling the humidifying device to maintain the atmospheric humidity of the desired moisture in the humidifying chamber or humidifier. Because we used this humidification method,
Humidification is smooth, and rice grains with less broken rice on the body side can be humidified.
