Description
Technical field
The utility model is related to a kind of for food, the concentration device for material liquid of medicine and other fields, more particularly to a kind of band four
The freezing concentrating device of logical reversal valve.
Background technology
In food, medicine and other fields, the concentration of feed liquid is a basic link in production process.Traditional feed liquid concentration
Concentrated more than device using heating power, i.e., feed liquid is heated to boiling temperature, make moisture vaporization discharge therein；Due to boiling vaporization
When, temperature is typically higher, and denaturation occurs or decomposes, and the quality to product after concentration brings unfavorable shadow in the heat-sensitive ingredients in feed liquid
Ring.
Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of band four-way concentrated at low temperature to feed liquid
The freezing concentrating device of reversal valve.
Structural principle signal of the present utility model is as shown in Figure 1.Including icing ice-melt unit and left container (7), right appearance
Device (6)；Compressor (1), auxiliary cooler (2), four-way reversing valve (3), right heat exchanger (5), expansion valve (4) and left heat exchanger (8) are logical
Cross pipeline and be sequentially connected composition icing ice-melt unit circulation loop, be filled with refrigerant in loop；Left heat exchanger (8) is located at left hold
In device (7), right heat exchanger (5) is located in right container (6).
The material of described left heat exchanger (8) is stainless steel material.
The material of described right heat exchanger (5) is stainless steel material.
Described expansion valve (4) is heating power expansion valve or electric expansion valve.
The beneficial effects of the utility model are：Feed liquid loss of heat-sensitive ingredients in concentration process is few.
Brief description of the drawings
Accompanying drawing 1 is direct mode operation principle schematic diagram of the present utility model；
Accompanying drawing 2 is commutating mode principle schematic diagram of the present utility model；
In figure：
1 is that cooler 3 is that four-way reversing valve 4 is expansion valve supplemented by compressor 2
5 be that right heat exchanger 6 is that right container 7 is that left container 8 is left heat exchanger
Embodiment
As shown in Figures 1 and 2, the utility model be the freezing concentrating device with four-way reversing valve, including freeze melt
Ice unit and left container (7), right container (6)；It is compressor (1), auxiliary cooler (2), four-way reversing valve (3), right heat exchanger (5), swollen
Swollen valve (4) and left heat exchanger (8) are sequentially connected in composition icing ice-melt unit circulation loop, loop by pipeline is filled with refrigeration
Agent；Left heat exchanger (8) is located in left container (7), and right heat exchanger (5) is located in right container (6)；The material of left heat exchanger (8) is
Stainless steel material；The material of right heat exchanger (5) is stainless steel material；Expansion valve (4) is heating power expansion valve or electric expansion valve.
When feed liquid needs concentration, first feed liquid is fitted into left container (7), pure water is fitted into right container (6), four-way commutation
Valve (3) is in pass-through state, and direct mode operation operation of the device as shown in accompanying drawing 1, compressor (1) starts, the high pressure-temperature of discharge
Gaseous refrigerant flows through four-way reversing valve (3) and is changed into high into continuation heat release in right heat exchanger (5) after auxiliary cooler (2) precooling
Middle temperature liquid refrigerant is pressed, after expanded valve (4) decompression flash distillation, low-pressure low-temperature liquid refrigerant is produced and enters left heat exchanger
(8) in, in the interior low-temperature refrigerant gasification absorption refrigeration of left heat exchanger (8), the moisture in left container (7) interior feed liquid is made in left heat exchange
The moisture that the surface of device (8) is formed in ice sheet, feed liquid is separated with other compositions, realizes the concentration of feed liquid；When left heat exchanger (8) table
When the ice sheet in face reaches certain thickness, compressor (1) is shut down, and direct mode operation terminates.
Next commutating mode is entered, as shown in Figure 2, now four-way reversing valve (3) is in commutation states, left container
(7) it is changed in pure water, right container (6) and is changed to feed liquid, compressor (1) is restarted, high temperature refrigerant gas is pre- through auxiliary cooler (2)
Cold to be changed again through four-way reversing valve (3) back into left heat exchanger (8), refrigerant heat release is changed into middle temperature liquid, while will be straight-through
The ice-out tied under pattern on left heat exchanger (8) surface；Produced after the middle expanded valve of temperature liquid refrigerant (4) throttling flash distillation low
Warm refrigerant liquid enters in right heat exchanger (5), absorption refrigeration and makes the moisture in feed liquid in right heat exchange in right heat exchanger (5)
Device (5) surface freezes, when the ice on right heat exchanger (5) surface reaches certain thickness and the ice-out on left heat exchanger (8) surface is finished
Afterwards, compressor (1) is shut down, and commutating mode terminates.
By direct mode operation and the periodicity alternate run of commutating mode, moisture is constantly frozen into ice and feed liquid in feed liquid
Other compositions separate and realize feed liquid and concentrate；Because freeze concentration process is carried out in a low temperature of 0 DEG C or so, feed liquid can be avoided
The denaturation or decomposition of middle heat-sensitive ingredients, it is easy to obtain high-quality concentrated product.
One embodiment of the present utility model is described in detail above, but the content is only of the present utility model
Preferred embodiment, it is impossible to be used to limit practical range of the present utility model.It is all according to present utility model application scope made it is equal
Deng change and improvement etc., all should still it belong within patent covering scope of the present utility model.
