Sifting · Model FSFJ
Single Bin Plansifter
The check sifter that keeps a bad batch out of a bag.
- 60+ years manufacturing
- 10–500 t/d capacity range
- 100+ patents
- Turnkey commissioning
What it does
A single-bin sifter sits immediately before the packer and inspects every kilogram of flour. It catches screen wire, lumps, foreign bodies and any oversize material from an upstream failure. Cheap insurance, and mandatory under most food-safety schemes.
Technical parameters
Nominal values at standard conditions. Confirm final specification on the order drawing.
| Parameter | FSFJ×12 (83) | FSFJ×12 sealed |
|---|---|---|
| Main shaft speed | 245 rpm | 245 rpm |
| Gyration diameter | 45–50 mm | 45–50 mm |
| Sifting area | 5 m² | 5 m² |
| Power | 1.1 kW | 1.1 kW |
| Dimensions | 1500 × 1500 × 2000 mm | 2200 × 1450 × 2000 mm |
Selection guidance
One per packing line. If you run three flour grades simultaneously, you need three check sifters — sharing one defeats the purpose because a failure in one stream contaminates the others.
Maintenance
Inspect the sieve frames weekly under strong light; a single pinhole defeats the entire machine. Replace wooden frames when they warp.
Selection cross-check
Plansifters: single bin vs double bin vs high square
Sifting is the second-largest power consumer and the constraint most flow sheets hit first. Bin configuration determines capacity per unit floor area.
This machine
Single Bin Plansifter
FSFJ
Choose it when
Small plants (under 40 t/d) with few passages, or as a dedicated machine for one product stream such as semolina or bran.
Watch out for
Lowest sifting area per square metre of floor. In a multi-passage flow sheet you would need several, each with its own drive and hangers.
Alternative
Double Bin Plansifter
FSFJ-D
Choose it when
Plants of 40–100 t/d where floor area is limited and you need two independent sifting streams in one frame.
Watch out for
Two bins share one drive, so a drive failure stops both streams. Access to the inner bin is tighter for screen changes.
Open Double Bin Plansifter →Alternative
High Square Plansifter
FSFG
Choose it when
Plants above 60 t/d, and the standard choice for any 4B5M1S1T flow sheet. Maximum sifting area per unit footprint, with each section independently fed.
Watch out for
Tall — needs 12.5 m or more of building height in a storey-typed plant. Section changes require working at height with proper access platforms.
Open High Square Plansifter →Decision rule
Sizing rule of thumb: 1 m² of sifting area per 0.8 t/d of capacity for a 4B5M flow sheet. Choose the configuration that delivers that area in the footprint you have.

Frequently asked questions
Straight answers to the questions engineers and mill owners actually ask us during plant sizing. If your case is not covered, send the wheat specification and your target tonnage.
Ask an engineer →- What is the difference between a check sifter and a plansifter?
- A check sifter inspects finished flour — one product, one pass, safety function. A plansifter grades mill streams — many products, many passes, process function.
