Description
Technical field
The present invention relates to milk quickly cooling device.
Background technology
Milk is the emulsion being mixed by materials such as water, albumen, fat, carbohydrate and calcium, phosphorus, iron, Vc, B10, proportion 028～038,0.54～0.59 DEG C of freezing point.The proportion 0.936～0.944 of fat (cream), 28～30 DEG C, freezing point.At present domestic each milk purchasing station cooling device is pot type intermittently chuck is cooling, and its volume 3～5m3 not etc., therefore, does not at least need to collect more than 3 tons milk and enters tank before milk is cooling, just begin to cool down operation.Cooling procedure is again that more than 3 tons milk is lowered the temperature simultaneously.Here it is collection milk, coolingly all need waiting time of relatively growing, the time of this " relatively long " has increased chance to bacterial reproduction, after particularly temperature raises, the time of " relatively long ", obvious especially to the bacterial reproduction increase in milk.
Summary of the invention
In order to solve above-mentioned technical problem, the object of this invention is to provide a kind of milk quickly cooling device.This device is cooling continuously, can reduce the collection milk time from source, has good cooling results, the feature of efficient energy-saving.
In order to realize above-mentioned object, the present invention has adopted following technical scheme:
Milk quickly cooling device, this device comprises chilled water unit, refrigerant cycle apparatus, milk cooler, receiver, milk heat insulation tank and washing agent cleaning device, described refrigerant cycle apparatus is by refrigeration machine, heat exchanger and compressor form, refrigeration machine is connected to described heat exchanger by the first refrigerant line, heat exchanger is connected to milk cooler by second refrigerant pipeline, described milk cooler comprises " U " type milk cooling coil and the cold-producing medium chuck that multiple tracks connects together, between " U " type milk cooling coil and cold-producing medium chuck, realize heat exchange, second refrigerant pipeline docks with the import of described cold-producing medium chuck, the outlet of cold-producing medium chuck is connected to described refrigeration machine by the 3rd refrigerant line, described compressor is connected on the 3rd described refrigerant line by magnetic valve is set, compressor is connected with described heat exchanger, described chilled water unit is made up of water circulating pump and cooling column, and cooling column is connected by water pipe with water circulating pump, cooling water is transported to heat exchanger and realizes the heat exchange between cold-producing medium and cooling water, the bottom of described receiver is provided with milk lifter, milk lifter is connected with the entrance point of " U " type milk cooling coil by check-valves, milk flowing pipe, in " U " type milk cooling coil, be provided with some twisted shape steel discs, twisted shape steel disc is several two segments compositions, torsional direction difference between two segments, scope from 90 to 180 degree, the port of export of " U " type milk cooling coil is provided with thermometer and triple valve, and the other two ends of triple valve are connected respectively to milk heat insulation tank and receiver.
As preferably, described washing agent cleaning device comprises washing agent storage tank and washings storage tank, and washing agent storage tank and washings storage tank are connected to described receiver after mixing by pipeline; Receiver check-valves rear end is provided with row's milk pipe, and row's milk pipe is provided with stop valve.
As preferably, described twisted shape steel disc is made up of left-handed and dextrorotation sheet, and left-handed and dextrorotation sheet are disposed in described " U " type milk cooling coil successively.
The present invention, owing to having adopted above-mentioned technical scheme, has following feature:
The first, cooling continuously, reduce the collection milk time from source.In the time that milk is collected 500kg, can start milk to send into cooler cooling down, then constantly supplement milk, like this can be the collection milk time shorten 83% before cooling, namely bacterial reproduction time decreased 83% left and right in milk, thereby control the bacterial population in milk.
The second, adopt direct heat transfer method.The evaporimeter of cold-producing medium and milk cooler are united two into one, and this heat exchanger is the evaporimeter of cold-producing medium, is again milk cooler, reduces like this equipment number of units, and simplification device reduces manufacturing cost.Cold-producing medium is directly evaporation in heat exchanger tube sleeve pipe, has increased the inside and outside △ t on two sides of heat exchange tube wall, improves heat-transfer effect.
The 3rd, in " U " type milk cooling coil, twisted shape steel disc is housed, the milk flowing through can be cut apart to mixing through 2*2n, greatly improve film coefficient of heat transfer.Meanwhile, 0.15 second with regard to divisible once with change flow direction once, make the fat in milk dispersed, keep original emulsion state, improve heat-transfer effect.
The 4th, adopt emulsification method washing milk cooling unit, can be more energy-conservation.Current washing milk cooling unit is to play saponification with NaOH and fat (cream), after generation fatty acid sodium salt, is dissolved in water, reaches and washs the object that is bonded at the fat (cream) on wall.This is chemical reaction process, needs certain external energy (alkali lye is heated to 70～85 DEG C) to promote that saponification completes.And the method for emulsification does not have chemical reaction, be only physical process, reduce the performance tension force of fat (cream) by the effect of surfactant, make to form in its droplet surface film or electric double layer, stop mutually condensing of these droplets, be dispersed in cleaning solution, reach cleaning object.The temperature of emulsion process is as long as more than fat (cream) fusing point (28～30 DEG C), set cleaning solution temperature 50 C, if 1 ton of each washing soda liquid, year can reduce 7.3*106kcal/a～12.7*106kcal/a heat exhaustion, and being converted to electricity is 8489kwh/a～14856kwh/a.
