A Tobacco Online Countercurrent Spiral Extraction Device

Abstract

The invention discloses an online countercurrent spiral extraction device for tobacco, which comprises a base, support columns are fixed on both sides of the top of the base, a first-stage extraction device is fixed on the top between the two support columns, and a primary extraction device is directly below the first-stage extraction device. There is a first-stage squeezing device, and directly below the first-stage squeezing device is provided with a second-stage extraction device, a second-stage squeezing device, a third-stage extraction device, and a third-stage squeezing device. The first-stage extraction device includes the first smoke soaking box, One side of the bottom end of the first soaking box communicates with the top side of the first squeezing box through the first feed pipe, and one end of the first soaking box is provided with a motor, which is protected by the fixing seat and the side of the first squeezing box. The cover is fixedly connected, and the present invention is an online countercurrent spiral extraction device for tobacco, which extracts the tobacco sequentially through three stages, reduces the consumption of water source, has high extraction efficiency, does not need to stop operation, improves work efficiency, is more environmentally friendly, has strong overall practicability, and is easy to extract. promote.

Description

technical field [0001] The invention relates to an extraction device, in particular to an online countercurrent spiral extraction device for tobacco, which belongs to the technical field of tobacco processing equipment. Background technique [0002] Tobacco is an annual or limited perennial herb of Solanaceae, Solanaceae, and Nicotiana, with a slightly lignified base. Inflorescences terminal, paniculate, many-flowered; capsules ovate or oblong, about as long as persistent calyx. It blooms and bears fruit in summer and autumn. The extraction of tobacco belongs to solid-liquid extraction, that is, leaching. The existing main means are water leaching method, chemical solvent extraction method, supercritical extraction method and so on. At present, a lot of research has been carried out on different extraction methods and their combinations, but most of them are in the experimental research stage, mainly used to extract nicotine, solanesol, chlorogenic acid, sugar and tobacco...
