Soaking extraction processing equipment and soaking extraction processing method

Abstract

The invention provides a soaking extracting processing device and a soaking extracting processing method. The soaking extracting processing device comprises a machine frame. A feeding device, a discharging device and a box are installed on the machine frame, an annular conveying device is installed in the box, and a plurality of water-permeable soaking boxes are installed on the annular conveying device; the annular conveying device comprises a feeding end and a discharging end, the feeding end corresponds to the feeding device, and the discharging end corresponds to the discharging device; the feeding end and the discharging end of the annular conveying device are located at the upper portion of the liquid level of the box; a water adding device is also arranged in the box. According to the soaking extracting processing device and the soaking extracting processing method, under the condition that breaking and waste of tobacco materials are reduced, soluble substances in the tobacco materials can be evenly and efficiently soaked and extracted, and the good basis is established for processing of the follow-up tobacco materials.

Description

technical field [0001] The invention belongs to the technical field of cigarette processing, and in particular relates to a processing equipment and a processing technology for improving the soaking extraction efficiency and homogenization processing level of tobacco materials. The invention can also be used for extracting traditional Chinese medicines and the like. Background technique [0002] In order to improve the product quality of cigarette products, reduce the consumption of tobacco raw materials, and reduce the content of harmful components in tobacco, the use of soaking extraction technology to extract harmful or adverse sensory substances in tobacco materials has been widely used, such as tobacco stems in tobacco leaves The proportion is about 25%. At present, the processing technology and equipment for making tobacco stems into shredded stems are quite mature. The proportion of blended shredded stems in cigarettes varies according to the grade of cigarettes. Howev...

Problems solved by technology

[0009] The above-mentioned patent uses countercurrent or downstream spiral equipment to soak the tobacco material to extract the soluble substances, which shows that it has a certain effect, but there are also problems. First, the strength of the tobacco stem or tobacco leaves is weak and easily broken after being shredded. , although the efficiency of soaking and extraction is the best at this time, part of the shredded tobacco will be broken under the action of spiral stirring water and mechanical friction, and the impurity content in the soaking liquid is relatively high, which increases the difficulty and cost of sewage treatment; the second , because when the screw pushes the material forward, it is impossible for the materials to run synchronously, and there is a difference in the extraction time and extraction rate of the material; third, it becomes difficult to extract the material with a large floating force, such as: tobacco stems and Tobacco leaves, etc.; Fourth, due to the difficulty in manufacturing, the precision of the gap between the screw and the shell is not easy to control, resulting in the accumulation of some materials, resulting in waste of materials

Since the homogenization processing level of soaking extraction is relatively low at present, it is urgent to have newer technological soaking extraction processing equipment to meet the requirements of improving the processing level of tobacco
