Cooling with carbon dioxide

A new plant which is using the latest refrigeration technology and a natural refrigerant has been set up by Prosper De Mulder for the processing of raw pet food materials.

The carbon-dioxide (CO2)-based cooling system, supplied by Star Refrigeration, is a vertical plate freezing system which replaces an ageing system at the customer's plant based at Doncaster in South Yorkshire.

The new installation makes use of CO2 as a refrigerant for freezing blocks of meat. It is highly energy-efficient and will provide long-term economic and environmental benefits, says Andy Pearson, Star's md. "The plant has reduced product freeze times at the processor," he claims.

The installation comprises a low-temperature carbon-dioxide circuit of two screw compressors and a surge drum/pump set serving 16 plate freezers, each with 26 stations. Total capacity is 1,000kW, capable of handling 185t of meat products a day.
