Description

Automatic cascade refrigeration quick-freezing plant
Technical field
The utility model relates to automatic cascade refrigeration quick-freezing plant, and it belongs to the quick-freezing plant field.
Background technology
In recent years, the high speed development of quick-frozen food output makes it require the cryogenic temperature of quick-freezing plant more and more lower.An existing quick-freezing plant part relies on freezer machine room cooling, adopts the form of two stages of compression mostly, uses ammonia refrigeration to be the master.Also some uses the helical-lobe compressor ammonia refrigeration separately.But the efficient of piston compressor is lower, and coefficient of refrigerating performance is low, system often can't operate as normal because suck too much air.Though adopt the screw rod machine certain improvement to be arranged on efficient, usually be affected because of pressure ratio is very high than piston machine.Adopt R22 can improve the pressure of inspiration(Pi) of compressor, but the R22 refrigeration is unfavorable for energy-saving and emission-reduction, runs in the opposite direction with the state basic policy of current sustainable development.
Summary of the invention
In view of the defective that prior art exists, the purpose of the utility model is through adopting a kind of new quick-freezing plant, fast and effeciently reduce cryogenic temperature, improving coefficient of refrigerating performance and refrigerating efficiency.Adopt the quick-freezing plant of automatic cascade Refrigeration Technique all more superior than two-stage piston type and screw.Reducing the discharge of pernicious gas simultaneously, is a quick-freezing plant that has energy-saving and environmental protection, reliability advantages of higher concurrently.
For realizing above-mentioned purpose, the technical solution that the utility model adopted is an automatic cascade refrigeration quick-freezing plant, and equipment comprises automatic cascade refrigerating plant, fast freezing case, band conveyer; The automatic cascade refrigerating plant is made up of compressor, evaporative condenser, segregator, gas-liquid separator, liquid reservoir; The air inlet of compressor links to each other with the exhaust outlet of evaporative condenser; The gas outlet and the segregator of compressor join; The outlet of segregator links to each other with gas-liquid separator, and gas-liquid separator lower end liquid outlet links to each other through restricting element with the evaporative condenser liquid inlet, and the liquid outlet of evaporative condenser is connected in the liquid reservoir inlet; The liquid reservoir liquid outlet links to each other with fast freezing case through restricting element, and the fast freezing case bottom is connected with the band conveyer.Said fast freezing case comprises fans, evaporator bank, supplying valve group, charging aperture, discharging opening; Evaporator bank is arranged in the fast freezing case, and fans places evaporator bank side or side-lower, and the inlet of evaporator bank is connected in the liquid outlet of liquid reservoir through the supplying valve group, and the exhaust outlet of evaporator bank and the exhaust outlet of evaporative condenser join.
Compared with prior art, the beneficial effect that the utility model had is: when adopting the automatic cascade refrigeration, and the comparable two stages of compression piston type of low-temperature quick-freezing device ammonia system energy-conservation about 40%; Than ammonia screw compression energy saving of system about 20%.Fast and effeciently reduce cryogenic temperature, improve coefficient of refrigerating performance, make frozen product can reach required refrigerating effect faster.Refrigeration occasion about-50 to-70 ℃ is with the obvious advantage, and ammonia that alternative present cryogenic refrigeration is generally adopted and R22 refrigerant system reduce the discharge of pernicious gas simultaneously, have concurrently energy-saving and environmental protection, reliability high etc. advantage.
