Powder extractor

Abstract

The invention relates to a powder extractor. A plurality of tank partition plates are connected between the front wall plate and the rear wall plate of a rectangular box body, the inner cavity of a box body is divided into a plurality of soaking tanks by the tank partition plates, an overflow port is formed in the upper part of each tank body partition plate, overflow ports on the adjacent tank body partition plates are arranged in a staggered mode in the front-back direction, the heights of the overflow ports is gradually reduced from right to left, the discharging end of the rightmost soaking tank is connected with a new solvent inlet, and the feeding end of the leftmost soaking tank is connected with a concentrated liquid outlet; a feeding port is formed above the feeding end of the leftmost soaking tank; the discharging end of each tank body partition plate is respectively provided with a material guiding groove for lifting materials towards the right side to turn the materials, and a discharging groove is formed in the discharging end of the right wall plate of the box body. The bottoms of the soaking tanks are arc-shaped and are respectively provided with a soaking tank spiral, the directions of the adjacent soaking groove spirals are opposite; a scraper lifting mechanism is arranged in each material guiding groove respectively, and a scraping plate discharging mechanismis arranged in the discharging groove. The powder extractor has the advantages that the soaking efficiency is high, powder scraps are reduced, and economic benefthe are improved.

Description

technical field [0001] The invention relates to an extraction device, in particular to a powder extractor, which can be used for dynamic extraction in industries such as food, environmental protection and chemical industry, and belongs to the technical field of extraction equipment. Background technique [0002] There are many types of extraction equipment on the market, including fixed bed, moving bed, basket bucket and filter cartridge. The general principle is that solids are naturally accumulated into a stable material bed or forced to form a stable material bed, the extract or washing liquid is poured in from above the material bed, and the liquid penetrates the material layer to complete the mass transfer process. [0003] This type of equipment has requirements on the particle size of solid materials. The solid materials should be in bulk or flakes. After accumulation, there should be a certain gap between the particles to facilitate the penetration of the extraction ...

Problems solved by technology

[0004] In addition, there are requirements for the physical and chemical properties of solids and liquids. Some solid components dissolve with liquid components to form viscous substances, which block the filter screen or grid, resulting in reduced or unsustainable extraction or washing processes. Frequent cleaning and maintenance are required. Soy Protein Concentrate Extraction

[0005] White bean flakes or low-denatured puffed materials, which are raw materials for processing soybean protein concentrate, contain 8-10% of high-powder debris, which cannot be processed by conventional leaching processes, and must be screened out and treated as scraps, resulting in economic yields of the material Low, poor sales, occupying funds

[0006] During the working process of the existing extractor, the contact between most of the solid materials and the extraction liquid is laminar flow contact, and the mixing with the extraction liquid is insufficient; A short circuit occurs, resulting in insufficient extraction power and low extraction efficiency; the extraction path seems to be long, but the utilization rate of the upper screen surface of each group of leaching units is very low

In addition, the concentrated extract extracted by the powder extractor contains a lot of powder particles, which will cause the blockage of the outlet pipe valve if it flows into the subsequent pipeline, so it must be filtered

After the traditional filter is used for a period of time, it will be clogged and the flow rate of the liquid will drop. It is necessary to replace or clean the filter element, which will affect the continuous and stable operation of the production line.
