DESIGN AND FABRICATION OF IMPROVE PERFORMANCE IN DEEP FREEZER

mechanical engineering

Techniques of freezing vary for each application. Later it has been discovered that the numbers of viable vegetative microorganisms in food are usually greatly reduced by freezing if quick freezing is employed. The conventional freezers could not cope with this higher rate of freezing. By the development of the deep freezer, the challenge of quick freezing has been met to enhance effective preservation by change the place of compressor, use the door handle and glass lid and use the manually operates flow control valve without using the capillary tube in Deep freezer. In the present work, a Deep freezer consisting of compressor at the bottom which consume more power to push up the refrigerants and when open handle door which wastage the cooled air, So by change the place of compressor reduce the power and using the glass lid which decrease wastage the cooled air and manually operated valve increase the effect of freezing.
