Seed cleaning machine grinding roll
SEED CLEANING MACHINE is the necessary seed processing equipment. The too high temperature and incomplete cleaning both can affect the equipment. Today, let’s analyze air draft and cleaning of seed cleaning machine grinding roll.
When the seed is ground into flour, part of mechanical energy is converted into thermal energy, which makes the seed cleaning machine grinding roll and material emit heat. And sometimes, the grinding roll surface temperature can reach 60-70℃. Then it may cause moisture condensation and form powder block at the surface of the seed cleaning machine housing and automatic flowing pipe and the conveying equipment. Besides, it may also cause low screening efficiency. If the seed cleaning machine grinding roll temperature is too high, it may cause protein denaturation. Seed bran will lose moisture after being heated and then becomes crispy and fragile.
Seed cleaning machine may cause lots of dust in production. When the dust accumulates to certain concentration, it may cause fire hazard. If the rotating grinding roll is mixed into metal impurities, or the seed cleaning machine grinding roll clearance is too short, then the two rolling techs may cause fire hazard due to crashing.
To inhale the moisture and dust, we should begin with air draft and dedusting. Usually each pair of grinding rollers have the following inhale volume: 5-6 cubic meters per minute. It adopts pneumatic transmission method in flour milling warehouse. At the same time with inhaling material, it can effectively inhale, cool and remove dust for the seed cleaning machine. The seed cleaning machine grinding roller adopts water cooling device and can make the fast roller surface temperature lower to 37-45℃. And the bearing temperature is also reduced. Meanwhile, it can make the ground material temperature reduce 5℃ so as to improve seed cleaning machine technological efficiency.
If the seed cleaning machine grinding roll surface has not enough cleaning, especially the grinding material has too high moisture content, and the grinding rollers have too large pressure, then it will makes the material bond the surface of the grinding roller or its tooth-shape groove.
