Sieve Cleaner

Efficient Grain Sorting

Discover the Zanin PSC 1 and PSC 5 sieve cleaners – reliable, quiet and easy-to-use solutions for cleaning grain and seeds. Using gravity-fed material flow and carefully selected perforated sieves, the machines provide efficient one- or two-stage cleaning and deliver a high-quality final product..

Zanin Sieve Cleners PSC 1 and PSC 5

The Zanin PSC sieve cleaners provide a reliable solution for cleaning grain and seeds to meet different needs. The sieve cleaner separates fine, medium and large impurities in the product and classifies the product using a one- or two-stage system.

PSC 1 is a single-stage cleaning system that effectively separates large and fine impurities, producing a clean and high-quality end product.

When more precise cleaning and calibration are required, the PSC 5 offers a two-stage process that removes light, coarse and fine impurities in two steps. This ensures high quality and careful seed grading even in demanding conditions.

Operating Principle of Zanin PSC 1 and PSC 5 Cleaners

PSC sieve cleaners use gravity feeding and a counterweight system that ensures even distribution of grain into the sieve box. Cleaning uses sieves made from perforated metal plates chosen according to the grain type being processed, which effectively remove impurities.

PSC 1 is a single-stage cleaning system where large and fine impurities are separated in a single sieving step. The upper sieve removes larger impurities and the lower one separates fine impurities. It is ideally suited for seed sorting and produces a clean, high-quality result.

PSC 5 uses a two-stage process in which airflow and sieves remove light, coarse and fine impurities in two consecutive stages. Before the grain exits, dampers even out the flow, and finally the airflow ensures remaining impurities are removed to a cyclone or filter. This achieves an exceptionally precise and thorough cleaning result.

Operating principle of the Zanin PSC 1 cleaner

1. Feed inlet for uncleaned product
3. Discharge channel for large impurities
4. Discharge channel for fine impurities
5. Discharge channel for cleaned product
