Abstract As society continues to progress, due to the high nutritional and palatability of milk, people gradually increased demand for milk, however, it is also milk because of its high nutritional and easy coexistence deterioration characteristics, how to preserve fresh milk has become a people concerned about the topic。 Fresh milk due to natural temperature is high, are highly perishable, and, after passing through the milk test, if not cooled storage as soon as possible, will soon degenerate losses。 In addition, many ranch no refrigeration facilities, and very far from the milk processing plant, milk output even just a simple stored during transport, after long-distance transport is also very perishable。 Therefore, a reasonable cooling milk storage is the key to the problem。
This paper analyzes the different milk cooling, combined with the background, using the appropriate cooling design, using chiller to cool the milk。 The design focuses on the design and configuration Refrigeration system design; refrigeration chiller design modalities, to prevent direct contact with the refrigerant milk, to avoid secondary contamination may occur。 Configuring the system is designed to MCGS configuration software system for data collection and processing Bian, fault automatic alarm, real-time monitoring。
Keywords:Cooling process; MCGS configuration software; chiller; real-time monitoring
