Description
Technical field
The invention belongs to Food Freeze Concentration field, be specifically related to a kind of Food Freeze Concentration device.
Background technology
The freeze concentration of food is a kind of food-processing method making the solvent crystallization in food by sub-cooled thus improve food concentration, freeze concentration is generally used for some to the more sensitive food liquid of ratio of specific heat, can also keep the natural aromatic material in product.Because freeze concentration energy consumption is low and concentrated product quality is high, therefore it has huge development potentiality.
Freeze concentration mainly comprises the following steps: the cooling of food liquid, the crystallization of food liquid, crystal are separated with concentrate.Current Food Freeze Concentration is normally carried out in freezing concentrating device, existing freezing concentrating device generally includes crystallisation chamber and separation chamber, the crystallisation by cooling of crystallisation chamber charge liquid food, separation chamber is responsible for being separated of crystal and concentrate, and crystallisation chamber and separation chamber normally separate, first food liquid is inputted during operation in the crystallisation chamber of low temperature and carry out automatic crystallisation by cooling, again concentrate and crystal are delivered to separation chamber together by pipeline after crystallization a period of time to be cooled to filter, the filtrate after filtration is required concentrate.
But, because food liquid is actionless during crystallisation by cooling in crystallisation chamber, and cooling medium is usually located at that crystallisation chamber is outer, itself and food liquid generation heat exchange time normally from outside to inside, therefore inner food liquid temperature can be made higher than the food liquid temperature of outside, namely food liquid is caught a cold inequality, thus in food liquid, the crystalline particle granularity of solvent is uneven, is not easy to filter, and the crystallization rate of food liquid can be made slow, thus cause whole concentration process efficiency low.In addition, the filter cloth in existing separation chamber is all laterally place, after filtration usually, crystal is blocked in filter cloth upper surface, and when the crystal accumulation thickness on filter cloth is larger, the follow-up rate of filtration can be more and more lower, thus affect separative efficiency, and then affect whole condensing crystallizing efficiency.
Summary of the invention
The technical problem to be solved in the present invention is the uneven and technological deficiency that separative efficiency is low of crystal size that is slow for existing Food Freeze Concentration device crystallization rate, crystallization, provide that a kind of crystallization rate is fast, the crystal size of crystallization evenly and the high Food Freeze Concentration device of separative efficiency.
In order to solve the problems of the technologies described above, the invention provides following technical scheme: Food Freeze Concentration device, comprise freezing moist closet, crystallisation chamber and separation chamber, described freezing moist closet top is provided with feed pipe, the top of described crystallisation chamber is connected with the bottom of freezing moist closet, crystallization chamber is provided with one group of crystallizer, crystallizer two ends are each passed through crystallisation chamber top and crystallisation chamber bottom, and crystallizer communicates with freezing moist closet, on the left of crystallisation chamber, the bottom of sidewall is provided with feed tube, and the top of crystallisation chamber right sidewall is provided with escape pipe, the top of described separation chamber is connected with the bottom of crystallisation chamber, and separation chamber communicates with crystallizer, the sidewall of separation chamber is provided with discharge nozzle, discharge nozzle is provided with suction filtering tube and circulation pipe, the end of suction filtering tube extends to the top of freezing moist closet, the end of circulation pipe extends in freezing moist closet, circulation pipe is provided with drawing liquid pump, discharge nozzle is positioned at the outside of suction filtering tube, and the outside being positioned at circulation pipe is provided with valve, the end of discharge nozzle is connected with aggregate tank, between discharge nozzle and one group of crystallizer, vertical filter cloth discharge nozzle and one group of crystallizer separated also is provided with in separation chamber, the bottom of separation chamber is provided with crystal outlet.
Adopt the Food Freeze Concentration device of technical solution of the present invention, comprise freezing moist closet, freezing moist closet is used for liquid towards food and carries out pre-cooled, thus efficiency when accelerating food liquid crystallization, the top of freezing moist closet is provided with feed pipe, for inputting food liquid, also comprise crystallisation chamber, crystallisation chamber is used for the crystallisation by cooling of food liquid, crystallization chamber is provided with feed tube, escape pipe and one group of crystallizer, feed tube is used for the input of liquid cooling medium, escape pipe is used for the output of cooling medium steam, crystallizer is used for the crystallisation by cooling of liquid food, is spaced apart from each other between one group of crystallizer, also comprise separation chamber, separation chamber is used for being separated of crystalline solid and concentrate, the sidewall of separation chamber is provided with discharge nozzle, discharge nozzle is for exporting concentrate, discharge nozzle is provided with suction filtering tube, circulation pipe, valve and the end of discharge nozzle is connected with aggregate tank, suction filtering tube is for accelerating the filtration of concentrate and crystalline solid, during enforcement, the end of suction filtering tube is connected with suction filter pump, suction filtering tube extends to the top of freezing moist closet, thus suction filter pump can be avoided to contact with concentrate, circulation pipe is used for the circulation crystallization of concentrate, concentrate is avoided to enter in aggregate tank when valve is used for circulation crystallization, aggregate tank is for collecting qualified concentrate, also filter cloth is provided with in separation chamber, filter cloth is used for the filtration of concentrate and crystalline solid, the bottom of separation chamber is also provided with crystal outlet, crystal outlet is used for the discharge of crystalline solid.
Know-why of the present invention and technique effect are: food liquid carries out pre-cooled in freezing moist closet, during enforcement, the temperature of freezing moist closet is adjusted to the crystallization temperature near solvent, thus when food liquid enters in crystallizer can crystallization rapidly, thus make the granule size of crystalline solid even, be convenient to isolated by filtration; Crystallizer is in the separate setting of crystallization chamber, cooling medium is still can be used for pass through between crystallizer and crystallizer, thus cooling medium promptly can cool the food liquid of inside, namely food liquid is caught a cold evenly, make the crystalline solid granule size of solvent in food liquid even, be convenient to isolated by filtration; Because discharge nozzle is positioned on the sidewall of separation chamber, filter cloth is vertical setting, therefore when crystalline solid moves to filter cloth surface because the Action of Gravity Field of himself can downward landing, thus avoid crystalline solid and be piled up in filter cloth surface and then avoid crystalline solid and hinder the subsequent filter of food liquid, make the isolated by filtration efficiency of concentrate and crystalline solid high.
Further, described filter cloth is obliquely installed, and the incline direction of filter cloth is towards one group of crystallizer.Thus more easily there is downward landing when moving to filter cloth surface in crystalline solid.
Further, described crystallizer is flat.Thus heat transfer area between food liquid and cooling medium is larger.
Further, the tapered shape in the bottom of described separation chamber.Thus it is easier to make crystalline solid derive.
