Probat

• Storage of roasted coffee beans in large-scale coffee roasting facilities.
• Integration into automated coffee processing lines for continuous supply to packaging or grinding stages.
• Buffering roasted coffee prior to further processing or dispatch in distribution centres.
• Used by large-volume coffee roasters, co-packers, and food manufacturers.

Typical capacity

For this class of equipment, individual silos commonly range from 500 kg to several tonnes of roasted coffee beans.

Construction material

Typically constructed from food-grade stainless steel or mild steel with a food-safe internal coating to prevent contamination and maintain coffee quality.

Discharge mechanism

Commonly features a conical bottom with a slide gate or rotary valve for controlled discharge, often integrated with pneumatic or mechanical conveying systems.

Footprint

The footprint varies significantly based on capacity and configuration (e.g., single or multiple silos). Buyers should consider available height and floor space.

Power supply

Ancillary equipment such as vibrators, level sensors, and discharge mechanisms typically require a 3-phase industrial power supply, commonly 400V, 50Hz in the UK.

Level monitoring

Units of this type often include level sensors (e.g., ultrasonic, capacitance) to monitor bean levels and prevent overfilling or running empty.

• Why are silos important for roasted coffee?

  Silos provide efficient bulk storage, protect roasted beans from environmental factors like oxygen and moisture, and facilitate automated handling and processing, maintaining product freshness and quality.

• Can these silos be used for green coffee beans?

• What is involved in dismantling and transport?

• Are these silos suitable for outdoor installation?

• What maintenance do coffee silos require?

Tanks and silos for food handling and storage are valued for their durability and reliability when purchased used. Buyers typically prioritize stainless steel construction for hygiene compliance and corrosion resistance. Key considerations include checking internal condition, seal integrity, and compliance with food safety standards. Industry sentiment reflects that quality used tanks offer significant cost savings whilst maintaining performance. Common strengths include longevity, straightforward maintenance, and compatibility with existing production lines. Proper inspection before purchase remains essential for operational safety.
