Abstract
A large or square plansifter has a large number of sieve stacks with e.g. more than 20 sieve boxes. Such boxes are constructed without a supporting grating and design so as to be exchangeable in the covered state and so that they can be placed on or in the sieve frames. A free product fall-through space or discharge space is accordingly formed between the sieve screen and a flat base plate. The sieve cleaners are placed on or in the flat base plate. In a particularly preferred manner, the sieve frames are constructed as metal frames. The sieve cleaners clean the sieve screen and clear the product from the base plate. The sieve cleaners preferably have 2, 3 or 4 arms.
