Embodiment Construction

[0019] A decompression ultrasonic combined extraction device, comprising an extraction tank 1, a condenser 4, a cooler 5, a gas-liquid separation device for keeping the extraction tank 1 in a vacuum state, an extraction tank 1, a condenser 4, a cooler 5, The gas-liquid separation devices are connected end to end and form a circulation loop through pipelines. The extraction tank 1 is provided with an ultrasonic generator 2 and a stirring device 3 under the liquid surface in the tank. The invention can not only keep the extraction always carried out under the low-temperature boiling state with a certain degree of vacuum and concentration, so as to ensure the product quality, but also improve the extraction rate of natural products and shorten the extraction time by using the ultrasonic modern extraction technology. The extraction tank 1 is equipped with an ultrasonic generator and a stirring device, and the ultrasonic vibrator and the stirring paddle are arranged under the inner ...

Abstract

The invention discloses a reduced pressure ultrasonic combined extraction device, which comprises an extraction tank, a condenser, a cooler, and a gas-liquid separation device used for keeping the extraction tank positioned in a vacuum state, wherein the extraction tank, the condenser, the cooler and the gas-liquid separation device are connected end to end and form a circulation loop through a pipeline; and the device is characterized in that: an ultrasonic generating device and a stirring device are arranged below a liquid level inside a tank body of the extraction tank. The device can keep extraction always operated under a certain vacuum degree, reaches a boiling state at lower temperature, shortens the extraction time, improves the product yield and quality and keeps activity of a natural product; moreover, the extraction time can be shortened further due to arrangement of ultrasonic equipment, and ultrasonic waves dissolve out substrates in a cell wall more easily, so that the product yield is greatly improved. The reduced pressure ultrasonic combined extraction device has great application market in the extraction process.

Description

technical field [0001] The invention relates to an extracting device, in particular to a combined extracting device. Background technique [0002] Most of the ingredients in natural resources are active and exist in large quantities in cells. Too low a temperature is not conducive to the dissolution of the extract, and too high a temperature will cause the extract to lose its activity. Therefore, the quality of the extract is not high and the efficiency is low, which is still a limitation of natural Bottleneck problem for full development of extracts. [0003] At present, normal pressure and micro-pressure processes are mostly used for extraction. Under these two processes, the boiling point temperature of the extract is relatively high, and many natural active ingredients will lose their activity, and some may even react to form other substances. The method of adopting normal temperature impregnation or pressurized percolation will take a long time, the efficiency is low, ...
