A high-efficiency continuous extraction device

Abstract

The invention provides an efficient continuous extraction device which comprises a frame and a rotary tank arranged on the frame and provided with a cavity inside, wherein one end of the rotary tank is provided with a feed opening, and the other end is provided with a discharge opening. The device is characterized in that at least two conical extraction chambers of which the head ends and the tail ends are communicated are arranged in the cavity of the rotary tank from the feed opening to the discharge opening; helical blades are arranged in each conical extraction chamber along the wall surface. Therefore, the mixing intensity of materials and extracts is effectively increased, and all materials are caused to be in full contact with the extracts in the continuous mixing process so as to greatly increase the extraction efficiency; simultaneously, the materials and the extract are fed into the tank cavity via the feed opening, and then continuously move to the discharge opening in the rotation and extraction process; solid and liquid are separated via a discharge net, and respectively discharged. The efficient continuous extraction device completely realizes the continuous extraction, is suitable for solid-liquid extraction at any solid-to-liquid ratio, completely meets extraction requirements of high and low concentrations, and saves the extract and energy required by concentration, and the phenomenon that the raw materials are polluted by leaking oil does not occur in the rotary tank.

Description

technical field [0001] The invention relates to an extraction device, in particular to a device for soaking plants and the like to extract active ingredients, and belongs to the technical field of design and manufacture of extraction equipment. Background technique [0002] Most of the traditional extraction devices soak plants etc. in a tank filled with soaking liquid to extract active ingredients by soaking. For example, utility model patents 96210476.0, 200520022234.2, etc., all adopt static soaking method to extract active ingredients. This static soaking method will cause a series of problems such as long extraction period, low extraction efficiency and waste of resources due to insufficient and unbalanced contact between plants and soaking liquid. In addition, due to the limitation of production time, the soaking time cannot be extended indefinitely, so that many active ingredients in the plant cannot be effectively extracted, which not only wastes plant resources, bu...

AI Technical Summary

Problems solved by technology

However, after a long period of production practice, it is found that it still has the problem of not being able to extract continuously, because the material inlet and outlet of the invention are the same, and the extraction can only be carried out one can at a time, and after each can is extracted, it needs to be extracted. After the material in the tank is emptied, new materials and soaking liquid can be fed in. Therefore, the extraction is discontinuous, and when the output is large, multiple tanks are required. There are many ancillary equipment, which takes up a lot of space and is difficult to control electronically.
