        Drying of rice and other crops, which is a heat-sensitive rice drying too fast or improper selection of parameters easier to crack. Composite paddy rice drying characteristics and to achieve quality and other factors, pay attention to the following measures:



        According to drying rice amount to determines with ranks, after rice drying entered sustained segment insulation time,it is grain internal water to surface diffusion, reduced grain internal of water gradient, then entered II times dry-sustained, common of sustained and dry time of ratio for 5~8:1, such on can reduced burst waist.

        A lower air temperature. In order to ensure the quality of dried rice and reduce the crack ratio, low air temperature must be used, if the 38~40℃ air temperature, the crack ratio value less than 2% of rice crack during drying, not only related to air temperature, and heat related to the initial moisture content of rheumatism and rice.

        Limit the drying rate of rice, rice drying or cooling too fast is prone to crack, in order to ensure the quality of rice drying, drying speed is not too large, should generally be controlled below 1.5%, hourly precipitation rate is not greater than 1.5%.
