Sieve cleaners sit in the compartment under the sieve cloth. As the plansifter gyrates they strike or sweep the cloth, freeing particles that would otherwise block the apertures. Without them, sieves blind, sifting capacity falls and flour quality drifts.
The main types
- Oval and rubber balls bounce against the cloth from below. Simple and effective on many passages.
- Triangle, big triangle and star cleaners carry brushes and studs. They sweep and tap at once, which suits fine flour passages.
- Rectangular cleaners with a metal or plastic knob suit rectangular compartments.
- Cotton cleaners are soft and gentle on fine synthetic fabric.
- Blue cleaners are easy to spot if a piece ever reaches the product.
Why quality matters
A sieve cleaner hits its frame hundreds of thousands of times a day. The plastic must be hard enough to work and elastic enough not to crack. Broken fragments can tear the cloth and contaminate flour, according to Milling and Grain magazine.
When to replace
- Studs or brushes are worn flat
- The body is cracked or chipped
- Sifting capacity has fallen even though the cloth is sound
Send us one cleaner or tell us the plansifter make and frame size, and we will match it.
