Problems solved by technology
Improper handling will result in running out of materials, and the running out materials must be recycled, which will not only cause drug pollution, but also pollute the environment
In order to overcome the following problems in extraction and concentration: ①Large solvent consumption and high consumption; ②High energy consumption and heavy pollution; ③The multi-functional tank is a double pressure dissolver, which limits the expansion of volume
In order to overcome the problem that there are many foams in the concentration, easy to run out of material, and cause pollution

Embodiment Construction
[0013] With reference to the attached drawings, the device of the present invention includes extraction tank 5, refluxer 1, concentrator 13, hot condensate pipe 4, extraction clear liquid pipe 6, 8, 9, steam pipe 11, secondary steam pipe 12, storage tank 7, 15 And the flow extract collection tank 14, the extraction tank 5 is a non-jacketed extraction tank, and the refluxer 1 is a thin-plate multiple-flow heat refluxer with a plate thickness of 0.5-1 mm, and the temperature of the reflux liquid is similar to that of the secondary steam. The concentrator 13 is an external thermal circulation type concentrator that does not produce foam, and is a stainless steel fully sealed device.
[0014] The extraction and concentration process is: the extract is continuously drawn from the bottom of the unjacketed extraction tank 5 into the double-flow plate concentrator 13, and the heating chamber of the concentrator 13 is heated to the boiling point and then sprayed into the evaporation chambe...

Abstract
The invention relates to an extraction concentration device and extraction concentration technique which is Liu family three-step extraction concentration device and extraction concentration technique, the device is a stainless steel airproof device which consists of extraction tank 5 without jacket, an outside heat-circulation type concentration device 13 which does not foam, the sheet double-flow type feedback flow device 1 in which the temperature of the feedback flow is close to that of the second steam and a technique pipeline. The device carries out the extraction, filtering and concentration at the same time and completes the production of the extract flow by one time, the device and the technique of the invention have the positive effects that one ton of the medicine extraction can reduce the amount of solvent for more than 10 tons, save 11 tons of steam converting into 1.83 tons of coal and reduce 5.4 tons of CO2 emission, can save time and improve the concentrated liquid yield by 15 to 20 percent.
Description
Technical field [0001] The invention relates to a concentration device and a process, in particular to an extraction concentration device and an extraction concentration process that are energy-saving, water-saving, resource-saving and emission reduction. Background technique [0002] At present, the well-known traditional Chinese medicine and food additive manufacturing industry uses multi-potential tanks to boil out the medicinal solution, settle in the sedimentation tank, filter through the filter, and concentrate by the concentrator. The process is carried out in sequence to complete the production of liquid extract in multiple steps. This process and process equipment There are the following drawbacks: [0003] 1. Boiling medicine: Boiling medicine in a multi-potential tank, heating the extract in the jacket with primary steam (boiler steam) to above the boiling point, so that the inside of the tank is pressurized, and the density of soluble substances in the medicinal mater...
