Joper DM 5-15

• Separating stones and other dense foreign objects from roasted coffee beans.
• Pre-cleaning various dry bulk products in food processing to remove heavy impurities.
• Ensuring product purity and protecting downstream grinding or milling equipment from damage.
• Improving the quality and safety of final food products by removing contaminants.

Typical capacity

For this class of destoner, throughput typically ranges from 5 kg/hr to 15 kg/hr, suitable for small to medium-scale roasting operations.

Power supply

Units of this type commonly operate on single-phase power, typically 220V-240V, with a motor rating around 0.37 kW.

Hopper capacity

Input hopper capacities for destoners in this range are typically between 30 kg and 60 kg, allowing for batch processing.

Footprint

These destoners are generally compact, designed to fit alongside roasters, with a footprint typically under 1 square metre.

Construction material

Commonly constructed from mild steel or stainless steel, with contact parts often in food-grade materials.

Separation principle

Typically employs vibration and air flow to separate materials based on specific gravity.

• What kind of impurities can a destoner remove?

  Destoners are primarily designed to remove heavier impurities such as stones, metal fragments, glass, and other dense foreign objects from lighter product streams like roasted coffee beans.

• Is this destoner suitable for green coffee beans?

• What maintenance is typically required for a destoner?

• Can the separation efficiency be adjusted?

• What safety features are commonly found on these units?

Sorting and grading equipment is valued for improving product consistency and processing efficiency. Buyers typically seek machines in good mechanical condition with minimal wear on critical components like belts, motors and calibration systems. Common strengths include reliable performance when properly maintained, cost savings versus new equipment, and compatibility with existing production lines. Industry sentiment favours models from established manufacturers known for durability. Buyers should inspect electrical systems thoroughly and verify spare parts availability before purchasing used units.
