A kind of drying unit of rice
The utility model relates to rice drying equipment technology, specially a kind of drying unit of rice.
The essential condition of rice safe storage is 24%~26% when making its water content by harvesting, and is dropped by being dried
To l2%~l4%, and make the relative humidity of air up to 50%~75%, it in this way could long-term storage.Therefore, before rice people library
It should first be dried, dryer is that vapor returns the standby equipment for returning material after setting temperature reduction with system in motion process in the same direction,
During the drying process, thermal current travels forward from tail portion, comes into full contact with material, and thermal energy is directly passed to material, makes material
Moisture be constantly evaporated in cylinder.
The method that China rice farmer mostly uses greatly natural drying, low efficiency, effect are poor, easy to pollute, loss is big, and pass
The rice drying equipment of system generally all only uses direct drying mode, during rice drying, is dried at one
In area, rice bulk deposition heating, drying is uneven, and internal rice cannot be oven-dried, and without rice the pre-heat treatment, instead
And make energy consumption bigger, and such drying effect and efficiency is not high.
