Description
Technical field
The present invention relates to the milk accelerate cooling system.
Background technology
Milk is the emulsion that is mixed by materials such as water, albumen, fat, carbohydrate and calcium, phosphorus, iron, Vc, B10, proportion 028 ~ 038,0.54 ~ 0.59 ℃ of freezing point.The proportion 0.936 ~ 0.944 of fat (cream), 28 ~ 30 ℃ at freezing point.Domestic each milk purchasing station cooling device is intermittently chuck cooling of pot type, its volume 3 ~ 5m at present
3Not etc., therefore, need at least to collect that milk enters tank more than 3 tons before the milk cooling, just begin to cool down operation.Cooling procedure is again that milk is lowered the temperature simultaneously more than 3 tons.Here it is, and the waiting time that all need relatively grow is suckled, cooled off to collection, and 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 the milk.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this invention is to provide a kind of milk accelerate cooling system.This system is cooled off continuously, can reduce the collection milk time from the source, has good cooling results, the characteristics of efficient energy-saving.
In order to realize above-mentioned purpose, the present invention has adopted following technical scheme:
The milk accelerate cooling system, this system comprises cooling water system, refrigerant-cycle systems, milk cooler, receiver, milk heat insulation tank and washing agent purging system; Described refrigerant-cycle systems is by refrigeration machine, heat exchanger and compressor consist of, refrigeration machine is connected to described heat exchanger by the first refrigerant line, heat exchanger is connected to milk cooler by the second refrigerant pipeline, described milk cooler comprises " U " type milk cooling coil and the cold-producing medium chuck that multiple tracks connects together, realize heat exchange between " U " type milk cooling coil and the cold-producing medium chuck, the 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 described the 3rd refrigerant line by magnetic valve is set, and compressor is connected with described heat exchanger; Described cooling water system is made 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 realizes heat exchange between cold-producing medium and the 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, be provided with some twisted shape steel discs in " U " type milk cooling coil, the twisted shape steel disc is that several two segments form, torsional direction between two segments is different, 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 purging system 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 comprised 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 has following characteristics owing to having adopted above-mentioned technical scheme:
The first, continuously cooling reduces the collection milk time from the source.When milk is collected 500kg, can begin milk is sent into the cooler cooling down, then constantly replenish milk, like this can be the milk of the collection before cooling time shorten 83%, namely the bacterial reproduction time decreased about 83% in the milk, thereby controlled the bacterial population in the milk.
The second, adopt the direct heat transfer method.Evaporimeter and the milk cooler of cold-producing medium 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 the 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 the twisted shape steel disc is housed, can be the milk that flows through through 2*2
nCut apart mixing, greatly improve film coefficient of heat transfer.Simultaneously, 0.15 second with regard to divisible once with change flow direction once, make the fat Uniform Dispersion in the milk, keep original emulsion state, improve heat-transfer effect.
The 4th, adopt emulsification method washing milk cooling system, can be more energy-conservation.The washing milk cooling system is to play saponification with NaOH and fat (cream) at present, is dissolved in the water behind the generation fatty acid sodium salt, reaches the purpose that washing is bonded at the fat (cream) on the wall.This is chemical reaction process, needs certain external energy (alkali lye is heated to 70 ~ 85 ℃) to promote saponification to finish.And the method for emulsification does not have chemical reaction, only is physical process, reduces the performance tension force of fat (cream) by the effect of surfactant, make and form film or electric double layer on its droplet surface, stop mutually condensing of these droplets, be dispersed in the cleaning solution, reach the cleaning purpose.As long as the temperature of emulsion process is set the cleaning solution temperature 50 C fat (cream) fusing point (28 ~ 30 ℃) more than, if each 1 ton of washing soda liquid, year can reduce 7.3*10
6Kcal/a ~ 12.7*10
6The kcal/a heat exhaustion, being converted to electricity is 8489kwh/a ~ 14856 kwh/a.
