Abstract
A sieve is disclosed for use in a plansifter. The sieve can be changed between backwire and combined sieve configurations without the height of the sieve changing, and while maintaining contact between a frame of the sieve and the sieve box. A dynamic combined cleaner also is disclosed in which the center of gravity of the cleaner dynamically changes based on inertial movements applied to the cleaner.
Claims9
A sieve for a plansifter configured to be interchangeable between a backwire configuration and a combined configuration, the sieve comprising:
- a sieve box having an open top and being divided into a sieving zone and a falling zone, the sieve box including at least one aperture through at least one wall within the sieving zone and at least one ledge along an interior of at least one wall within the sieving zone;
- and
- a removable frame configured to fit within the sieving zone of the sieve box, the frame having an overhang portion configured to sit on an edge of the sieve box around the sieving zone and an extended portion configured to sit on the at least one ledge,
- wherein the extended portion defines a notch at a bottom of the frame configured to accept a backwire grille between the at least one ledge and the frame, with the sieve configured as the backwire sieve, without changing an overall height of the sieve.
