Description

Quick-frozen beverage sales machine

The utility model relates to a kind of quick-frozen beverage sales machine, is liquid beverage equipment, be suitable for to liquid such as beer, various fruit drink, water freeze, fresh-keeping.

Present existing quick-frozen beverage sales machine, major part are to be agent for storage of coldness with water, and volume is big, and Heavy Weight is difficult for moving, and starting is slow, and starting shooting just goes out cooled drink liquid after one or two hour.

The purpose of this utility model provides a kind of compact conformation, and starting is fast, and volume is little, and conveniently moving efficient height is energy-conservation, economizes material, the quick-frozen beverage sales machine of temperature constant.

Primary structure of the present utility model comprises condenser, device for drying and filtering, and compressor, evaporation coil, expansion valve, low pressure controller is into and out of beverage three-way connection parts, installing plate, parts such as blower fan.Condenser is located at the right side on the installing plate, device for drying and filtering is located at middle part, back on the installing plate, compressor is located at installing plate upper left side middle part, expansion valve is located at middle part, front on the installing plate, low pressure controller is located at left side, back on the installing plate, evaporation coil is located at below the installing plate, and blower fan is located at above the installing plate, near condenser.All link to each other between each parts with tube connector, its unique distinction is that evaporation coil adopts sleeve type structure, the several tubules of cover in the extra heavy pipe, refrigeration working medium freon flows in the extra heavy pipe, cooled drink liquid flows in the tubule, adverse current between the two, directly carry out heat exchange, thermal resistance is little, and heat transfer temperature difference is big, reduce the volume of heat transfer structure effectively, save tubing, the time that goes out cold beverage is short, is provided with at the evaporation coil two ends, go out beverage three-way connection parts, advance beverage three-way connection parts, be located at below the installing plate, join with evaporation coil one end, that end above going out beverage three-way connection parts and evaporation coil stretching out installing plate links to each other, advance, go out beverage three-way connection parts, by seal receptacle, sealing shroud, the sealing fuse is formed with turnover beverage joint.

Expansion valve, be used for regulating automatically the refrigeration working medium flow, under the big situation of refrigeration duty change, regulate liquid supply rate automatically, make operating condition reliable and stable.

Low pressure controller is to be connected on the air intake duct of compressor by a capillary, controls the keying of its contact by experiencing pressure of inspiration(Pi).Dynamic and static two contacts are connected in the control circuit of compressor, control the open and close of compressor by the keying of contact.Because pressure of inspiration(Pi) and evaporating pressure approximately equal, freon evaporating pressure in evaporation coil is crossed when hanging down, then its evaporating temperature can be low excessively, drink liquid can freeze, before freezing, drink liquid compressor must cut out, its objective is that preventing to drink liquid by the low pressure controller differential pressure value of setting freezes, avoid high frequent to start.

The utility model has the advantages that compact conformation, light, fast, high, the good refrigeration effect of heat transfer coefficient of starting, use reliable, economize material, energy-conservation, the drink liquid temp is stable.Can regulate automatically, be provided with and prevent to drink the liquid parts that freeze, start at any time, going out to drink liquid at any time is the quick-frozen beverage equipment that better uses.
