Description
Technical field
The utility model relates to a kind of concentration technique field, particularly relates to a kind of low temperature enrichment facility.
Background technology
Concentrating is the unit operations of removing partial solvent from solution, is the part separation process of solute and the even mixed liquor of solvent.Freeze concentration is finished at low temperatures, have and to stop the characteristics that adverse chemical changes and biochemistry changes, simultaneously local flavor, fragrance and nutritive loss are little, are specially adapted to concentrate thermal sensitivity food liquid, bio-pharmaceuticals, requirement and keep the high-grade drink of natural colour fragrance and traditional Chinese herbal decoction etc.
Low temperature concentrates in the prior art two kinds of patterns: suspended crystallization method and interface nibbling method.
Suspended crystallization method at first becomes supercooled state with feed liquid to be concentrated in heat exchanger, enter crystallizing tank then and form a large amount of little ice crystals, ice crystal is separated with concentrate again.The advantage of this method is that can to form the concentration of clean ice crystal and striking point rapidly higher, and shortcoming is that the Separation of Solid and Liquid of ice crystal and concentrate is relatively more difficult.In actual applications, owing to need kind of a brilliant generation, crystalline growth, three main processes of Separation of Solid and Liquid are finished system's relative complex respectively in different devices.For cleaning concentrate subsidiary on the ice crystal, need ice crystal is washed, produce a large amount of cleaning fluids and need reflux again concentrated.The investment of this device is big, running cost is high.
The interface nibbling method is to form a freezing interface in certain side of solution to be concentrated, water in the feed liquid constantly solidifies the formation ice sheet at freezing interface, growth thickening along with ice sheet, the feed liquid of near interface thickens, solute is rejected to liquid side, the concentration of solute raises gradually in the liquid phase, up to reaching required concentration.Because the interface nibbling method forms the ice crystal of an integral body, solid liquid interface is little, and concentrate is very easy with separating of ice crystal, the method complex structure, and ice crystal purity is not high.
The utility model content
The purpose of this utility model is at the technological deficiency that exists in the prior art, and provides a kind of simple in structure, and concentrated effect is good, can export the low temperature enrichment facility of concentrate and ice crystal continuously.
For realizing that the technical scheme that the purpose of this utility model adopts is:
A kind of low temperature enrichment facility, it is characterized in that, comprise cylindrical shell, for the auger conveyor that the ice of cylindrical shell bottom is boosted, for the heater of heating and melting ice partly with for the refrigerating plant that freezes solution in the cylindrical shell, described auger conveyor is installed in the described cylindrical shell, described cylindrical shell is provided with inlet, on the cylinder body outer wall on described inlet top described heater is installed, on the cylinder body outer wall of described inlet bottom described refrigerating plant is installed, the bottom of described cylindrical shell is provided with the concentrated solution outlet, described cylindrical shell top is provided with the ice outlet, is equipped with on the described auger conveyor and wipes the scraper of icing on the cylinder inboard wall off; The ice that is advanced to cylindrical shell top partly melts, and flows downward along described auger conveyor, forms heat exchange with the ice that rises, and the solution that flow to the bottom is freezed again, forms bigger concentration gradient in cylindrical shell.
Described cylindrical shell is the good conductor of heat.
Described refrigerating plant is the low-temperature coil in the refrigeration system.
Described heater is the high temperature coil pipe in the refrigeration system.

Figure 1 shows that the schematic diagram of low temperature enrichment facility.
Among the figure: 1. cylindrical shell, 2. heater, 3. auger conveyor, 4. refrigerating plant, 5. inlet, 6. concentrated solution outlet, 7. ice outlet.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Figure 1 shows that the schematic diagram of low temperature enrichment facility, the auger conveyor 3 that comprise cylindrical shell 1, is used for the ice of cylindrical shell bottom is boosted, be used for the heater 2 that heating and melting partly ices and the refrigerating plant 4 that is used for freezing solution in the cylindrical shell.Described auger conveyor 3 is installed in the described cylindrical shell 1, described cylindrical shell 1 is provided with inlet 5, on the cylinder body outer wall on described inlet 5 tops described heater 2 is installed, on the cylinder body outer wall of described inlet 5 bottoms described refrigerating plant 4 is installed, the bottom of described cylindrical shell 1 is provided with concentrated solution outlet 6, described cylindrical shell top is provided with ice outlet 7, is equipped with on the described auger conveyor and wipes the scraper of icing on the cylinder inboard wall off.The ice that is advanced to cylindrical shell top partly melts, and flows downward along described auger conveyor, forms heat exchange with the ice that rises, and the solution that flow to the bottom is freezed again, forms bigger concentration gradient in cylindrical shell.
Described cylindrical shell 1 is the good conductor of heat, and material is not limit, and can be stainless steel, titanium steel or pottery.
Described heater 2 is the high temperature coil pipe in the refrigeration system.Described refrigerating plant 4 is the low-temperature coil in the refrigeration system.
Liquid enters into cylindrical shell 1 inside from inlet 5, at cylindrical shell 1 bottom low-temperature coil 4 glaciation of solution part is attached to cylindrical shell 1 inwall, because the motion of auger conveyor 3 scrapes ice crystal with the blade on the auger conveyor 3 from cylindrical shell 1 inwall, carry to cylindrical shell 1 top simultaneously.When ice crystal is delivered to cylindrical shell 1 top by auger conveyor 3, under the effect of high temperature coil pipe 2, the part ice crystal melts, and the solution after the thawing flows downward along the helix of auger conveyor 3, realize heat exchange with the ice crystal of upwards carrying, form " rectifying " effect.So repeatedly, the ice that is transported to cylindrical shell 1 top by auger conveyor 3 is more and more purer, and the solution of cylindrical shell 1 bottom is more and more denseer, and concentrate flows out along concentrated solution outlet 6.
The above only is preferred embodiment of the present utility model; should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
