What Affects Oat Hulling Machine Yield Under Certain Conditions

When the oat is ground into flour, part of mechanical energy is converted into thermal energy, which makes the oat hulling 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 oat hulling machine housing and automatic flowing pipe and the conveying equipment. Besides, it may also cause low screening efficiency. If the oat hulling machine grinding roll temperature is too high, it may cause protein denaturation. Oat bran will lose moisture after being heated and then becomes crispy and fragile.

Oat hulling 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 oat hulling 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 oat hulling machine. The oat hulling 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 oat hulling machine technological efficiency.

If the oat hulling 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.
