• Roasting various types of nuts, such as almonds, cashews, and peanuts, for snack food production.
• Processing coffee beans to develop flavour profiles for the beverage industry.
• Roasting cocoa beans as an initial step in chocolate manufacturing.
• Drying and roasting seeds and grains for cereals, baking ingredients, or oil extraction.

Typical capacity

Roasters in this class commonly handle batch sizes ranging from 30kg to 120kg, with 60kg being a common mid-range capacity.

Power supply

Industrial roasters typically require a three-phase electrical supply, commonly 400V, 50Hz, with varying amperage depending on heating elements and motor size.

Heating method

Units of this type often utilise gas (natural gas or LPG) or electric heating elements for precise temperature control.

Cooling system

An integrated or separate cooling system is typically present to rapidly cool roasted products and prevent over-roasting.

Construction material

Roasting drums and contact parts are commonly constructed from food-grade stainless steel for hygiene and durability.

Footprint

A 60kg batch roaster typically requires a floor area of approximately 2m x 1.5m, plus space for ancillary equipment like destoners or afterburners.

• What maintenance is typically required for a used roaster?

  Regular maintenance for a used roaster commonly includes checking and cleaning the roasting drum, burners/heating elements, cooling fan, and exhaust system. Bearings and drive components should also be inspected and lubricated as per manufacturer guidelines.

• Can this type of roaster be used for different products?

• What are the common safety features on industrial roasters?

• What ancillary equipment might be needed with a roaster?

• How important is the year of manufacture for a used roaster?

Used roasters are valued for their durability and cost effectiveness in food processing operations. Buyers typically prioritise even heat distribution, temperature control consistency, and robust construction when selecting secondhand units. Industry sentiment favours roasters from established manufacturers known for reliable performance. Key considerations include maintenance history, heating element condition, and capacity matching operational requirements. Well-maintained roasters often deliver dependable service across coffee roasting, nut processing, and other food applications, making them sound investments for processors seeking to minimise capital expenditure.
