Grain Cleaning Machine

PSSILO Sieve Cleaner is a rotary drum cleaning system designed for efficient cleaning and grading of grains, oilseeds and legumes before storage or further processing.

The system combines screening and aspiration to separate light, fine and oversized impurities from the product stream. Different sieve opening sizes allow the machine to be configured according to the characteristics of the processed product and the required cleaning result.

The continuous rotation of the drum provides consistent product movement through the cleaning section while supporting efficient separation and reliable operation.

MULTI-PRODUCT CLEANING

PSSILO Sieve Cleaner can be used for a wide range of agricultural products including:

• Wheat
• Barley
• Corn / Maize
• Oats
• Rice
• Soybeans
• Sunflower seeds
• Rapeseed
• Leguminous seeds
• Other suitable cereal and agricultural products

Sieve configuration and operating parameters are selected according to the characteristics of each product.

SCREENING & IMPURITY SEPARATION

During the cleaning process, the incoming product passes through sieve sections with selected opening sizes.

Fine impurities are separated through the sieve openings, while larger foreign materials are discharged separately at the end of the drum.

The system can remove unwanted materials such as:

• Straw
• Wood fragments
• Corn cob pieces
• Oversized foreign materials
• Fine impurities
• Light impurities
• Dust and waste

Removing these materials before storage or processing helps protect downstream equipment and improves the quality of the product entering the next process stage.

ASPIRATION SYSTEM

Light impurities are separated from the product stream through aspiration.

The combination of mechanical screening and air separation allows different types of contamination to be removed within the cleaning process.

The aspiration system can also be integrated with the plant dust collection system according to project requirements.

PRE-CLEANING, CLEANING & GRADING

The PSSILO Sieve Cleaner can be configured for different applications according to product and process requirements.

Typical applications include:

• Rough / Pre-Cleaning
• Precision Cleaning
• Seed Cleaning
• Product Grading

This flexibility allows the same cleaning principle to be adapted to different stages of grain receiving, storage and processing operations.

SELF-CLEANING SIEVE SYSTEM

The sieve system incorporates a self-cleaning mechanism that helps keep sieve openings clear during operation.

Rollers support continuous sieve cleaning while the drum rotates, reducing clogging and helping maintain consistent screening performance.

The system is also capable of separating large foreign materials without blocking the product inlet and outlet sections.

ADJUSTABLE DRUM OPERATION

Operating conditions can be adjusted according to the type of product and the impurities that need to be separated.

The drum angle can be adjusted through a motorized mechanism, allowing product movement through the cleaner to be adapted to operating requirements.

Drum rotation speed can also be adjusted electronically, providing greater control over product flow and screening performance.

EASY SIEVE CHANGE & MAINTENANCE

Different products and cleaning requirements may require different sieve opening sizes.

The side cover provides practical access to the sieve sections, allowing sieves to be changed quickly according to the product being processed.

The rotary drum design and accessible internal components also simplify routine inspection and maintenance.

PROCESS CONTROL

The screening process can be checked during operation through dedicated sampling and control points.

This allows operators to evaluate cleaning performance and make adjustments to the machine settings when required.

PROTECTION OF DOWNSTREAM EQUIPMENT

Removing straw, wood fragments, corn cob pieces and other foreign materials before they enter the grain handling or processing line helps protect downstream equipment.

The Sieve Cleaner can therefore be positioned before:

• Grain dryers
• Storage silos
• Bucket elevators
• Conveying systems
• Feed mills
• Grain processing equipment

This creates a cleaner and more consistent product stream for subsequent operations.

COMPLETE SYSTEM INTEGRATION

PSSILO Sieve Cleaner can be integrated into complete grain receiving, cleaning and storage systems together with:

• Grain unloading pits
• Intake conveyors
• Bucket elevators
• Aspiration and dust collection systems
• Grain dryers
• Storage silos
• Distribution systems
• PLC & automation systems

This allows grain receiving, cleaning, conveying and storage to operate as one coordinated process.

WHY PSSILO?

PSSILO Sieve Cleaner combines rotary screening, aspiration and adjustable operating parameters to provide flexible cleaning for different grains, oilseeds and legumes.

Self-cleaning sieves, adjustable drum angle, electronically adjustable rotation speed and easy sieve replacement allow the system to be adapted to different products and cleaning requirements.

When integrated with PSSILO grain receiving, conveying, drying and storage equipment, the cleaner becomes part of a complete grain management system rather than operating as an isolated machine.
