Problems solved by technology

[0002] Through the liquid with intermediate concentration after one concentration, when the concentration of the liquid is increased, the specific gravity and viscosity of the concentrated liquid will increase at the same time during the re-concentration operation, so the concentration process becomes very difficult
The existing technology is to use a batch-type jacketed mixing tank, which takes a long time to remove water to achieve the purpose of concentration

Embodiment Construction

[0020] Such as figure 1 As shown, the continuous high-concentration liquid concentration device of the present invention includes a liquid supply container 1, a liquid supply pump 2, a vapor-liquid separator 6, a condenser 7, a vacuum pump 8, a jacketed single-pipe heater 3, an evaporation vessel 4 and Concentrate receiving tank 5.

[0021] The liquid supply pump 2 is used to continuously, quantitatively, and high-pressure deliver the medium-concentration liquid from the liquid supply container 1 to the jacketed single-tube heater 3. In the closed space of the intermediate concentration liquid, the vacuum pump 8 is used to draw a vacuum to the closed space of the evaporation container 4, and the vapor-liquid separator 6 and the condenser 7 are arranged in the pipeline connecting the vacuum pump 1 to the evaporation container 4, and the vapor-liquid separator 6 and the condenser Devices 7 are successively arranged along the moving direction of water vapor in the pipeline. The...

Abstract

The invention provides a continuous high-concentration liquid concentration device and a continuous high-concentration liquid concentration method. The method comprises the following steps of: heating median-concentration liquid which is conveyed continuously and quantificationally under high pressure; and evaporating the heated median-concentration liquid under a vacuum environment and separating water vapor to obtain the high-concentration liquid. The device comprises a device used for heating the median-concentration liquid which is conveyed continuously and quantificationally under high pressure and a device used for evaporating the heated median-concentration liquid under the vacuum environment and separating the water vapor to obtain the high-concentration liquid. The median-concentration liquid is conveyed continuously and quantificationally under high pressure and is heated, and an attractive force is applied to the liquid by vacuum, so heat exchange process can be performed completely even if the median-concentration liquid is concentrated to be the high-concentration liquid. The method and the device have the characteristic of economy, so the operation has the characteristic of high planning property.

Description

technical field [0001] The invention relates to a liquid concentrating device and a liquid concentrating method, in particular to a concentrating device and a concentrating method for extracting liquids of Chinese patent medicines or natural seasonings that need to be concentrated to a higher concentration after one concentration. Background technique [0002] When the concentrated liquid has an intermediate concentration after being concentrated once, the specific gravity and viscosity of the concentrated liquid will increase at the same time when the concentration of the liquid is in a state of rising, so the concentration process becomes very difficult. The prior art adopts batch-type jacketed stirring tanks, which take a long time to remove moisture to achieve the purpose of concentration. Contents of the invention [0003] The object of the present invention is to provide a continuous high-concentration liquid concentration device and a continuous high-concentration l...
