Twin Roto Sifter 1350 for Flour Screening

Twin Roto Sifter 1350 — High-Capacity Sieving for Flour Mills

Flour production is a volume game: consistency, hygiene, and uptime directly affect yield, margins, and export readiness. The SIVTEK Twin Roto Sifter 1350 is engineered for flour mills that need reliable, high-throughput sizing without surrendering floor space or product integrity. By pairing two centrifugal sifting chambers in a single compact machine, the Twin Roto delivers up to 30 tons/hour for flour applications giving mills the capacity of multiple machines in one hygienic package.

Why flour mills choose the Twin Roto Sifter 1350

Traditional vibratory sifters struggle with low bulk-density powders like flour: blinding, dust, and fines handling cause frequent stops and yield loss. The Twin Roto Sifter tackles these problems head-on:

Massive throughput in a small footprint: Twin centrifugal chambers via a common splitter which almost doubles and beyond the capacity of a single Roto Sifter up to 30 t/h for flour without doubling floor space.
Hygienic, enclosed system: The closed, dust-tight design not only supports food-grade processing but also decreases the risk contamination while keeping the surroundings clean.
Low noise and vibration: The Twin Roto has been designed to operate very quietly (<80 dB) and with virtually no vibration, making it perfect for continuous production lines where operator comfort is important and for equipment stability.
Fast, safe cleaning: The cantilever three-bearing shafts and fast access inspection windows allow quick disassembly and cleaning for allergen control and frequent product changeovers.
De-blinding options: Brush, rubber wiper blade, and pneumatic de-blinding accessories reduce mesh clogging and maintain throughput when processing fine, oily, or fibrous flours.

How centrifugal screening tuned for flour?

The Twin Roto Sifter is based on the principle of centrifugal screening meant for powders having low bulk density. Material is fed into a common inlet and split evenly between two rotating screening chambers. In each chamber, the beater bars generate centrifugal force, which pushes the particles onto the cylindrical mesh. The fine particles go through the screen while the larger particles are transported to a different place for discharge. Continuous de-agglomeration prevents clumping and maintains consistent particle distribution critical for flour quality and downstream processing.

The twin arrangement means two centrifugal actions run in parallel: throughput multiplies, while product handling remains gentle. The machine’s closed system even allows vacuum-assisted processing if the application requires it.

Key features:

Capacity up to 30 t/h for flour applications high throughput in a compact footprint.
A choice between a dual motor or a pulley drive depending on site power and maintenance preferences.
A splitter feed that ensures uniform distribution and stable operation even at changing feed rates.
Three-bearing cantilever shafts provide fast tool-free access to the internal sieve for inspection and cleaning.
Hygienic enclosed design with inspection windows dust-tight and audit-friendly.
Low noise (<80 dB) & negligible vibration for operator comfort and equipment reliability.
De-blinding systems: brush, rubber wiper blade, or pneumatic arrangements to maintain throughput with oily or fibrous flours.
Flexible mesh options (stainless steel, nylon, specialized polymers) for varied flour grades.

Real benefits for flour processors

Consistent particle size and consistency of product quality is especially important for baking performance, blending, and downstream dosing.
Higher effective throughput achieves production targets while minimizing equipment count.
The cleaning time is reduced and the easy access and de-blinding options keep the lines moving.
Cleaner operations, having safer operations, is that which limits the risk of airborne dust and contamination.
Adaptable to product mix quick mesh changes and hygienic design support frequent changeovers.

Final word

The Twin Roto Sifter 1350 is an attractive option to the flour mills that want to increase capacity and maintain hygiene, uptime, and product quality. It packs the performance of multiple centrifugal sifters into one compact, hygienic, and operator-friendly machine capable of handling up to 30 t/h while keeping noise, vibration, and product loss to a minimum.
