Rotary drum defroster 600 mm

Drum defroster for fruits and vegetables 600 mm

The rotary drum defroster is designed for the continuous thawing and tempering of frozen food products before further processing. The rotating drum gently tumbles the product throughout the defrosting process, promoting uniform exposure of all pieces and allowing melt water to drain continuously through the perforated drum.

Continuous product movement helps prevent large frozen masses from remaining stuck together (Unlike static thawing methods), improving thawing uniformity and reducing processing time before subsequent operations such as cutting, mixing, cooking, coating, or packaging. The gentle tumbling action minimizes mechanical damage while separating frozen pieces as they thaw.

The perforated drum continuously removes melt water during operation, helping prevent the product from remaining submerged and improving overall process hygiene. The machine is manufactured entirely from food-grade stainless steel for hygienic operation and easy cleaning in food processing environments.

• Suitable for a wide range of bulk or pieced frozen food products
• Food-grade stainless steel construction ensures hygienic operation and long service life
• Compact industrial design provides high processing capacity while requiring relatively little floor space
• Optional frequency converter allows adjustment of drum rotation speed according to product characteristics
• Optional discharge conveyor enables continuous unloading and easier integration with downstream equipment
• Continuous operation allows integration into food processing lines for efficient production

Basic version

The basic version includes a perforated stainless steel rotating drum mounted on a stainless steel support frame with an industrial geared drive unit, spraying system for warm/hot water, and adjustable support legs to adjust the drum tilt angle. The drum is designed to provide continuous gentle product movement while allowing melt water to drain throughout the defrosting process.

Operating principle

Frozen product is continuously loaded into the rotating drum through the inlet section. As the drum rotates, the product is gently lifted and tumbled, continuously exposing all surfaces and promoting uniform thawing. At the same time, cold melt water drains through the perforated drum, preventing excessive water accumulation around the product.

As the product progresses through the drum, it gradually reaches the discharge section, where it is unloaded or transferred onto an optional discharge conveyor, and moved up for further processing.
