Filter device, treatment process and application thereof

Abstract

The invention provides a filter device for high-concentration herb residues and / or fruit residues. The device comprises a feeding component, a filter screen cartridge (2), a connecting shaft (6), a liquid receiving component (3), a power component (4), a transmission component (5) and a stand column (8). Under the rotation of the filter screen cartridge (2), herb residues and / or fruit residues, which are extracted by a solvent, are gathered into clusters in the screen cartridge and roll along with the rotation of the screen cartridge; herb residue clusters and / or fruit residue clusters form cracks in the rolling process and then are clustered again. The filter device has an effect of promoting the seepage of liquid in the herb residues and / or fruit residues, therefore an extracting solution or original juice are fully removed, and the solid-liquid separation effect is realized. The filter device is suitable for the berry or fruit kind of fruit residue treatment and is also suitable for filtering the extracted residues of other plants such as maca, kelp, abelmoschus esculentus, abelmoschus manihot, cistanche and cynomorium songaricum.

Description

technical field [0001] The invention belongs to the field of biochemical engineering equipment, and relates to a filtering device and a filtering process, in particular to a filtering device, a treatment process and an application of medicinal dregs and / or pomace. Background technique [0002] The extraction and deep processing fields of food and traditional Chinese medicine all involve the steps of filtering and removing slag. Low-viscosity medicinal residues such as ginkgo leaf extraction residues and licorice extraction residues can be fully filtered by using conventional mesh screens combined with filter cloth, while high-viscosity medicinal residues, such as wolfberry, kelp, okra, etc., still contain a large amount of residue after extraction. The extracts are often not recovered well, resulting in a lot of waste; or the recovery steps are more complicated, such as plate and frame filtration, extrusion filtration, etc. For example, patent CN203540163U discloses a pomac...

AI Technical Summary

Problems solved by technology

Low-viscosity medicinal residues such as ginkgo leaf extraction residues and licorice extraction residues can be fully filtered by using conventional mesh screens combined with filter cloth, while high-viscosity medicinal residues, such as wolfberry, kelp, okra, etc., still contain a large amount of residue after extraction. The extraction liquid is often not recovered well, resulting in a lot of waste; or the recovery steps are more complicated, such as plate and frame filtration, squeeze filtration, etc.

For example, patent CN203540163U discloses a pomace filter using an elastic filter screen, but its processing capacity is small and time-consuming, which is not suitable for large-scale production; Squeeze medicinal dregs to filter medicinal liquid, which has a low degree of automation; patent CN200963547Y discloses a solid-liquid separation and filtration device for filtering solid particles in a fluid, which requires a large amount of fluid to provide driving force for filtration, which consumes resources Huge and expensive to recycle
