Giesen - Giesen Destoner OW50

Applications & Use Cases

• 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 Specifications

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.

Frequently Asked Questions

• 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?
