Sub-0 home freezer

摘要

An occasional use domestic counter top flash freezer. To accomplish this, all aspects of the refrigeration process have been scaled down into a unique and economical flash freezer for the home, here to for unavailable to the consumer. A refrigeration engine is contained within a light weight and low cost enclosure; and chills a diminutive cold chamber to temperatures substantially below −18° C. The cold chamber is sized to accommodate a small batch of foodstuffs at a time, such that the rate of heat removal effects flash freezing; the process of preventing formation of large cellular ice crystals. This appliance is an adjunct to a domestic home refrigerator/freezer, enabling the consumer, for the first time, to effectively freeze foodstuffs for later consumption, while not sacrificing taste! Thus, it will do for food preservation what the microwave has done for food preparation in the home.
