In flour mills, the square plansifter is used for the classification of the product coming from the roller mills and detachers. It provides high sifting capacity in limited spaces. The sifter is used by hanging it to the ceiling using fiberglass hanging rods and it consists of three main parts: two sieve boxes housing the sifter frames with sieves and a drive section that houses the motor and the counterweights. Inside the sieve boxes, there are synthetic resin coated frames and sieves.
The product entering the plansifter can be separated into 7 different varieties. The use of wide frames can increase the sifting surface by up to 22%. Every sifter passage can fit up to 32 frames. For ease of transportation, the machine can be divided into three parts. The surfaces in contact with the flour are painted with food grade paint and it can also be covered with stainless steel upon request.
