Principle 
- The grain is fed tangentially into the horizontal special-designed rotor. Intensive scouring of the grain is achieved through the interaction between the 
A, grain and products 
B, grain and rotor blades 
C, grain and sieve 
- The grain is conveyed to the outlet by the rotary blades while the grain surface is scoured and the attached impurities scraped from the grain pass through the sieve and then be collected.

Application 
- The horizontal scourer is generally working together with an aspiration channel or a recycling aspiration channel at its outlet. They can efficiently get rid of detached shell particles or surface dirt from the grain. 
- Successful used in the cleaning section for the surface cleaning of wheat, durum and rye 
- With the suitable rotor and sieve jacket designs, the scourer can also be applied for intensive processing and scouring for oats and durum.
