Advantages

 1. High shelling efficiency, up to 95%

 2. Excellent chemical and phsical properties. 
 3. Good in heat and abrasion resistance.
 4. Good in temperature and weather resistance .

 5. Strong bonding between rubber roll and drum

Usage and Attention

1. Optional of Rubber Roller: For the choice of  the black, brown and white rubber roller with  hardnes shore A 90^oC and 95^oC, it should be according to the type of rices, climate conditions, and different seasons.Try to avoid to use the single roller,  the recommended way is higher hardness for fast roller, lower hardness for slow roller.

2.Temperature and Hardness Control: The proper hardness is shore A 82-86^oC, and the temperature is below 50^oC. When the temperature reaches above 60^oC,  the hardness of roller should be reduced 4-8^oC

3. Alternative use of rubber rollers is recommended:
A: It can increase the usage life of roller and quantity of dehusking rice.

B: Each roller has break time during the working, which is good for recoving the function of rubber, adjusting the speed difference 

    upon on different diameters, and controlling the temperature effectively.

4. Two rollers should be at the same level to keep the space equal.

5. The paddy inputting should keep the balance.

6.  Keep the rate of the re-hulling under the limitation

7. Storage:

A: Avoid the direct sun shine and soaked in the rain and snow.

B: Away from the heating device about 1.5m. 

C: Store in dry and clean place, away from acid, alkali, salt, oil and organic solvent.

D. Keep the room temperature 10-30^oC, comparative moisture 50-80^oC 
E. Keep in vertical position,  horizontal is not allowed.

F. No other materials pressure on it, no hitting to avoid deformation and damage
G. Validity of storage life: one year.
