This small electric grain drying machine is a small and electric machine for drying different grains for farmers. It can dry the cocoa beans, coffee beans,wheat,corns,rice, green beans and so on.
Such as the rice, the rice is different from other grain drying, rice is a heat-sensitive crop, too fast drying or improper selection of parameters prone will break the rice. Comprehensive characteristics of rice and rice drying should be achieved the quality and other factors, during drying of rice, people should pay attention to the following aspects of the measures:
1. Selection of preheating→drying→slow materials→cooling→process grian, the "dry - slow soviet" process is just according to the number of dried rice to determine a common level, that is, after drying rice into the slow Soviet section of insulation For a period of time, the water spread to the surface of the grain to reduce the water gradient within the grain, and then into the second drying - slow Soviet Union, the commonly used slow-drying and drying time ratio is about 5 to 8;
2. This machine is desigened with lower hot air temperature. In order to ensure the quality of rice after baking and reduce the rate of breaking, you must use a lower hot air temperature, if you use 38 ~ 40 ℃ hot air temperature, the broken rate can reduce 2%, rice drying process is not only related with hot air temperature, but also with the hot water content and the initial moisture of rice.
3. limitting the drying rate of rice, rice drying too fast or too fast cooling are prone to burst, in order to ensure the quality of dry rice, the drying rate can not be too large, generally should be controlled at 1.5% or less, that is not greater than 1.5 per hour precipitation rate.
