Rotary drum freezers consist of a sloping cylindrical drum, which is rotating around its axis.
Rotary drum freezers require continuous input of product. Dohmeyer can propose buffer hoppers and supply conveyors to convert discontinuous product flows into continuous input.
Rotary drum freezers are best used for IQF freezing of free rolling, mostly small products. They are perfect for products consisting of separate pieces. Applications in the food industry are abundant: rotary drums freeze individual pieces (granules, crumps, cubes.. ) of fish and meat, pasta, vegetables and precooked dishes to IQF quality.
UNIQUE DOUBLE DRUM DESIGN
For certain products it is best to use a double drum:
– the first, short and fast turning drum serves to freeze the surface of the product, – the second, long and slow turning drum freezes the product in depth.
FEATURES AND BENEFITS
Dohmeyer’s cryogenic rotary drum freezers can be tailor made. Inclination, rotating speed, baffles,… can all be adapted to the specific needs of the customer. Rotary drum freezers are compact and often take up less space than other types of IQF freezing systems.
