TH21122EX - Cryogenic heat exchanger and cryogenic drying equipment - Google Patents

Abstract

Refrigerated heat exchanger And refrigeration drying equipment which are combined, heat exchanger in In the freezing state, there will be a knowledge exchange device that has At least one channel For receiving cold fluids used in Heat transfer has a reverse flow cycle, which acts in reverse. The direction of the flow of the chilled fluid is used for pouring heat to prevent uneven ice formation in the heat exchanger. The fluid used to transfer the used heat is circulated. Go back and use again During rotation The chilled fluid used to transfer the activated heat is mixed with the fed cryogen to form the chilled fluid used in the Heat transfer: a chilled fluid used to transfer heat The resulting flow is fed to the reverse flow circuit and then passed to the heat exchanger. The cold fluid used in Heat transfer that is still lost. Remaining will be drained. Circulation increases the heat transfer temperature in the heat exchanger and facilitates ice sticking. The heat exchanger can be a condensation device, which is used in the freeze drying apparatus by freezing the steam that is released between The freeze drying process is also used in the application of Use this invention properly The reverse flow system is coupled with the circulation and mixing system. Can be used in the exchange system Self-defrosting heating
