5 results about "Circulation evaporator" patented technology

This utility model relates to the field of heat exchange improvement technology for freezers, specifically to a freezer structure with an embedded recirculating evaporator, including a freezer shell, a foamed inner liner laid along the inner wall of the freezer shell, and a heat exchange system embedded in the foamed inner liner. The heat exchange system includes a vapor-liquid separator, an evaporator, a compressor, a condenser, and a throttling device. This utility model embeds the vapor-liquid separator of the recirculating evaporator into the foamed layer near the freezer opening, solving the problem that recirculating evaporators with vapor-liquid separators cannot be used in small-scale commercial freezers, thus broadening its application range.

This utility model discloses an evaporation crystallization system, aiming to solve the shortcomings of existing multi-effect evaporation crystallization equipment, such as limited cycle times and high initial investment. The utility model includes a preheater, a plate falling film evaporator, a circulating heater, a circulating evaporator, a crystallizer, and a crystal slurry tank connected in sequence. The circulating heater includes a first circulating heater and a second circulating heater. The outlet of the plate falling film evaporator is connected to both the plate falling film evaporator and the evaporator's inlet. The circulating evaporator has a separation outlet and a separation inlet. The circulating evaporator is connected in series with the first and second circulating heaters via the separation outlet and then connected to the separation inlet. This achieves a flexible crystallization system that enables continuous production through multiple evaporation cycles, reducing initial investment and floor space requirements.
