Giesen OW50

• Used in coffee processing facilities to remove stones and other dense foreign objects from roasted coffee beans.
• Applicable in small-scale food processing operations for cleaning various granular products.
• Utilised in specialty food production where product purity is critical.
• Integrated into coffee roasting lines to protect grinders and ensure product quality.

Typical capacity

For this class of equipment, capacities commonly range from 50 kg/hour up to several hundred kg/hour, depending on the specific configuration and product density.

Power supply

Units of this type typically operate on a single-phase 230V, 50Hz supply, though some larger models may require three-phase power.

Footprint

Compact destoners are designed to minimise floor space, commonly requiring an area of approximately 0.5 to 1 square metre.

Construction material

Typically constructed from stainless steel for contact parts to ensure hygiene and durability, with a painted mild steel frame.

Separation principle

Operates on an aspiration or vibration principle, using air flow and density differences to separate heavier foreign objects from the product.

Maintenance requirements

Generally low maintenance, primarily involving regular cleaning of screens and inspection of air filters and fan components.

• What kind of foreign materials can a destoner remove?

  Destoners are primarily designed to remove heavier foreign objects such as stones, metal pieces, glass, and dense clumps that are mixed with the product.

• Is this suitable for products other than coffee beans?

• How does a destoner protect downstream equipment?

• What is the typical efficiency of a destoner?

• Are spare parts readily available for Giesen equipment?

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.
