The Combined Cleaner And Destoner Machine For Grain Cleaning is a versatile and efficient grain cleaning solution designed for wheat, corn, paddy, beras, barley, oats, sorghum, millet, soybean, and other granular crops. Grain varies greatly in kernel size, shape, bulk density, moisture content, surface friction, and impurity composition. This machine combines screening, aspiration, and gravity destoning in one compact unit to remove large impurities, small impurities, light impurities, stones, mud balls, and heavy contaminants. It prepares clean, uniform grain for milling, feed processing, seed production, storage, and further separation.

Working Principle

Grain enters the machine through the feed inlet and is evenly distributed onto the upper sieve deck. The upper sieve removes large impurities such as straw, cobs, stalks, strings, and large debris. The lower sieve removes small impurities such as sand, fine dust, broken kernels, and small seeds. At the same time, an adjustable aspiration system removes light impurities such as dust, chaff, husks, and light straw.

The pre-cleaned grain then flows onto the destoner deck. The deck performs a vibrating and upward-air movement that causes grain particles and stones to stratify by specific gravity. Heavier stones and mud balls sink to the deck surface and move upward to the stone outlet, while lighter grain floats and moves downward to the clean grain outlet. The vibration amplitude, air volume, and screen mesh can be adjusted according to different grain types, moisture levels, and impurity conditions.

Parameter

Features

• Integrated screening, aspiration, and destoning: The machine combines upper and lower sieve decks, an air aspiration system, and a gravity destoner deck in one unit, removing large, small, light, and heavy impurities from different grains.

• Multi-layer sieve decks with quick-change screens: Screen meshes can be selected or changed according to grain type and kernel size, such as wheat, corn, paddy, barley, soybean, dan sorgum.

• Adjustable vibration, stroke, and air volume: The operating parameters can be adjusted for grain with different bulk density, moisture content, shape, and impurity levels, ensuring stable cleaning performance.

• Enclosed dust-tight structure with wear-resistant destoner deck: The closed design reduces dust escape, improves the working environment, and protects the machine from wear during long-term grain cleaning.

Advantages

• High cleaning efficiency for multiple grains: The combined design removes large impurities, small impurities, light dust, stones, and mud balls in one continuous process, reducing the need for separate cleaning machines.

• Gentle grain handling: Optimized vibration and air flow reduce impact and breakage, which is especially important for fragile grains such as wheat, barley, and paddy.

• Flexible operation for varied grain conditions: The machine can be quickly adjusted for different grain varieties, moisture levels, capacities, and impurity contents, making it suitable for diverse processing lines.

• Compact and reliable structure: The combined cleaner and destoner saves floor space, reduces conveying points, and lowers maintenance requirements compared with multiple single-function machines.

Benefits

• Improved grain purity and final product quality: Cleaner grain means better flour quality in wheat mills, higher rice purity in rice mills, and more consistent feed or seed products.

• Protection for downstream equipment: Removing stones and heavy impurities prevents damage to hullers, destoners, mills, rollers, conveyors, and other processing equipment, reducing repair costs.

• Higher productivity and yield: Continuous and stable cleaning helps grain processing lines achieve higher capacity, less downtime, and better overall efficiency.

• Better working environment and lower labor costs: Dust control and automatic impurity discharge reduce manual cleaning, improve operator safety, and create a cleaner workshop.
