Sieve cleaner brushes help flour to be cleaned through wire and plastic mesh by moving on the sieves. While doing the cleaning process it is important for the brush to reach the corners of the silk. Because, it increases the machine's efficiency by reaching to the every corner and prevent accumulation on the sieve. It is a very common problem that brushes get wear off over time. This cause little pieces to break off from the brush and mix with the flour. To prevent this problem, we are using first class pure polyurethane.
