Giesen Destoner OW50

• Removing stones and other dense foreign objects from green coffee beans prior to roasting.
• Pre-cleaning various dry bulk products such as grains, pulses, and nuts.
• Enhancing product purity and protecting downstream processing equipment from damage.
• Used in small to medium-scale food processing operations requiring precise material separation.

Typical throughput

For this class of equipment, throughput commonly ranges from 50 kg/h to 200 kg/h, depending on the product and contamination level.

Power supply

Units of this type typically operate on a single-phase 230V, 50Hz electrical supply.

Construction material

Commonly constructed from stainless steel for food contact areas, with painted mild steel for the frame and non-contact components.

Separation principle

Typically employs a vibrating deck and airflow to separate heavier impurities from lighter product based on density.

Footprint

For a unit suitable for a 15-25kg coffee roaster, the footprint is generally compact, often less than 1 square meter.

Airflow requirements

Requires a dedicated air supply or an integrated fan system to create the necessary separation effect.

• What types of contaminants can a destoner remove?

  Destoners are primarily designed to remove heavier contaminants such as stones, metal pieces, glass, and other high-density foreign materials from a product stream.

• Is this destoner suitable for products other than coffee?

• How is the separation efficiency typically adjusted?

• What maintenance is typically required for a destoner?

• Does a destoner also remove lighter impurities like chaff?

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.
