Sifting : Seiving

Description

Sifting

Remove coarse granules and aerate the raw materials for better processing and protection of equipment downstream. The sifters that we offer have all parts in contact with the product constructed to meet food quality guidelines. Depending on throughput capacity, location space and type of material, sifters of various sizes are available.

Sifter A
In-Line Sifting

As the In-Line sifters are inserted directly into the pneumatic conveying system for removal of oversized impurities, there is no need to switch to (atmospheric pressure) gravity flow sifting and back to pneumatic again.

Thus, saving a great deal of both initial investment cost and subsequent operating, maintenance and sanitation costs throughout the system’s life. Another important benefit of In-Line sifting is that it enables sifting protection to be placed close to the finished product, minimizing contamination from any extra equipment after sifting.

The In-Line sifter works like a multi-sieve gravity-flow sifter except that it operates at the pressure or vacuum of the pneumatic conveying line. An air bypass arrangement equalizes the air pressure above and below the sifting screens. Thus, no force other than gravity causes the product to fall through the screens.

The product enters at the top center, passes through screens and is discharged to side channels. Oversized particles end up in a sealed tailings canister at the bottom of the sifter.

Sifter B
Rotary sifters

High-quality rotary sifters for food, chemical, plastic processing and pharmaceutical industry as well as for small industrial bakeries. The compact, sturdy, rotary sifters, operating on the proven rotation principle, have all parts in contact with the product constructed not only to meet food quality guidelines of the European Hygienic Engineering & Design Group and BG regulations but also designed for easy cleaning.

The feeding screw and beater bars are equipped with double bearings and sealed from the product area with additional sealing rings. The sifter screens are made of polyester or polyamide. When used as an in-line sifter, it can be connected directly into the pressure or vacuum conveying line for a pressure tight operation of up to 0.8 bar or vacuum pressure.

Depending on throughput capacity, location space and type of material, sifters of various sizes are available.
The machine housing and inner components are made of stainless steel and inlet housing and cover are made of cast aluminum alloy.

Whichever model, the sifter continuously breaks up clumps, removes coarse granules and aerate the raw materials for better processing and protection of equipment downstream. A pressure hopper for cleaning of
the sifter drum is optionally available.
