Abstract
The utility model discloses a freeze concentration device with a rotary drum, belongs to the technical field of freeze concentration for food liquid, and aims to overcome the shortcomings that the conventional freeze concentration equipment is difficult to separate ice from concentrated liquor and high in solute loss. The freeze concentration device with the rotary drum comprises a liquid tank and a support, and is provided with the rotary drum, the lower half portion of the rotary drum extends in the liquid tank, the rotary drum is rotatably arranged on the support by a hollow center shaft of the rotary drum, and a refrigerant liquid inlet tube and a refrigerant liquid outlet tube are respectively arranged at two ends of the hollow center shaft. The freeze concentration device is applicable to a freeze concentration process for food liquid materials.
Description
Technical field
The utility model relates to a kind of Freeze Concentration Technology of food liquid feed liquid, particularly relates to a kind of drum-type freeze concentration device.
Background technology
In food-processing industry, it is that water content is very high that a lot of materials are arranged, like beer, orange juice, syrup, instant coffee, grape wine etc.In process: in order to remove the most of moisture in the food material, to reduce the expense of packing, storage and transportation; Through improving the concentration of goods, reach the purpose that increases goods storage property; For satisfying the technical process requirement of food processing, as as the preliminary treatment of product drying dehydration or crystallization etc.; Must carry out concentration to material, manage from material solution, to remove part moisture, make material finally reach the metastable state of a low water content.In current food processing enterprises, usually adopt the Steam Heating vacuum to concentrate and two kinds of technologies of freeze concentration to concentrating of material, because the heat and the equipment dynamic consume significant of Steam Heating vacuum concentration process; And the relative power consumption of technology for freeze concentration is less; Simultaneously heat sensitive food is concentrated advantageous particularly; Have low-temperature operation, gas-liquid interface is little, and microbial growth is few; The loss of the deterioration of solute and volatile aromatic composition can be controlled in extremely low advantages such as level, therefore receives the welcome than multiple enterprises.Because technology for freeze concentration is that a part of water in the solution is separated out with the form of ice; And, exist the isolation technics of ice crystal and concentrate to require height with the method that it is separated from liquid phase, operate very complicated problems; When the viscosity of solution is big, separate more difficulty; Exist the solid liquid interface between ice crystal and the concentrate bigger simultaneously, when brilliant liquid separated, partial concentration liquid can be carried secretly because of ice crystal and cause the solute loss.
Summary of the invention
The purpose of the utility model provides a kind of drum-type freeze concentration device, overcomes present freeze concentration equipment, and is difficult with separating of concentrate to ice crystal, the deficiency that the solute loss is bigger.
The utility model is achieved through following technical proposals.
The utility model comprises material liquid tank, support, is provided with rotating cylinder, and the Lower Half of said rotating cylinder stretches in the said material liquid tank and is loaded on rotationally on the support by its hollow axis, at two ends of said hollow axis the cooling medium liquid inlet pipe is housed respectively, cooling medium liquid goes out pipe.In the utility model, cooling medium liquid can flow into through said cooling medium liquid inlet pipe, in said rotating cylinder, goes out pipe from said cooling medium liquid again after the heat absorption and flows out; Make said rotating cylinder remain low-temperature condition; When the Lower Half of the rotating cylinder of low temperature contacted with feed liquid in said material liquid tank, the moisture in the feed liquid will be separated out the surface that is attached to said rotating cylinder with the form of ice sheet, when said rotating cylinder slowly rotates; Its surperficial ice sheet will slowly produce the feed liquid face together with said drum surface, can remove easily.
The utility model is provided with scrapes the ice device; The said cutting edge of scraping the ice device is affixed on the first half of said rotating cylinder; Cutting edge towards relative with the rotation direction of said rotating cylinder, remove tying with mechanical mode in the ice sheet of said drum surface, can alleviate working strength of workers greatly.For said rotating cylinder is rotated continuously, motor and gearbox are housed on said support, on the output shaft of said gearbox driving gear is housed; On said hollow axis, driven gear is housed, said driving gear and the engagement of said driven gear are connected with power line on the said motor.
Against existing technologies, the beneficial effect of the utility model is:
Make the ice liquid lock out operation of technology for freeze concentration fairly simple and convenient, significantly reduce the outfit and the power consumption of relevant device; Interface between ice crystal and the concentrate is greatly reduced, reduced the solute loss of feed liquid effectively.
Description of drawings
Fig. 1 is the structural representation of the utility model, and Fig. 2 is that the A of Fig. 1 is to view.Among the figure: 1, material liquid tank, 2, support, 3, rotating cylinder, 4, hollow axis, 5, the cooling medium liquid inlet pipe, 6, cooling medium liquid goes out pipe, 7, scrape the ice device, 8, motor, 9, gearbox, 10, driving gear, 11, driven gear, 12 power lines.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to describe.
The cooling medium liquid that is adopted in the utility model can be used calcium chloride brine; And cooling medium liquid is remained at be full of level a little less than rotating cylinder 3 one half volumes; When operation, can not overflow like this; Cooling medium liquid inlet pipe 5 and cooling medium liquid go out between the inwall of pipe 6 and hollow axis 4 can exist the gap, the power that rotating cylinder 3 is rotated with saving.The liquid sucting port that cooling medium liquid goes out pipe 6 must be immersed under the liquid level of cooling medium liquid, and the available pumping of the circulation of cooling medium liquid should be established heat exchanger in circulating pipe system, make cooling medium liquid remain low temperature.At the afterbody of scraping ice device 7, can establish collection ice groove, collect the ice bits that scrape, so that focus on.During use, at first in material liquid tank 1, fill it up with feed liquid to be concentrated, let cooling medium liquid flow in the rotating cylinder 3 from cooling medium liquid inlet pipe 5 again, the heat absorption back is gone out pipe 6 outflows and is kept circulation by cooling medium liquid.Then, start motor 8, rotating cylinder 3 is slowly rotation just, has tied the surface of ice sheet and has produced the feed liquid face gradually, finally forwards the cutting edge place of scraping ice device 7 to, and ice sheet is scraped, and so repeats, and accomplishes the concentration technology to feed liquid.
