Problems solved by technology

[0004] However, when using the above extraction device to extract tea seeds, peanuts, hemp and other high oil content (40%-60% oil content) kernel raw materials, due to the high oil content of the raw materials, the bulk density of the raw materials during the extraction process As the extraction progresses, the change is obvious: as the oil in the material is continuously extracted, the organizational structure of the material will become looser, that is, the bulk density of the material will become smaller and smaller, and there will be more and more The powdery raw materials are susp

Embodiment 3

[0055] The method for using the extraction kettle containing the self-moving material balance filtering device comprises the following steps:

[0056] 1) Open the top of the extraction basket 13, which contains the filter screen or the filter plate, pour the material into the extraction basket 13 from the mouth of the basket, and then place the self-moving material balance filter device 23 on the top of the material. Good material basket cover; Put extraction material basket 13 in the extraction kettle, and cover still lid 9 well.

[0057] 2) Open the carbon dioxide inlet pipe 27, so that the carbon dioxide is evenly distributed into the extraction chamber through the circulation pipe 26 and the distribution holes of the distributor to extract the materials in the extraction basket 13;

[0058] 3) During the material extraction process, the self-moving material balance filter device 23 moves up and down in the extraction basket 13 under the rolling of the large ball 81. When t...

Abstract

The invention discloses a self-moving material balance filtering device, an extraction kettle containing the same and a use method. The device comprises a circular ring mounting base and a pressing ring arranged below the circular ring mounting base; a filtering piece is arranged between the circular ring mounting base and the pressing ring, a plurality of ball mounting bases are evenly arranged on the upper surface of the circular ring mounting base along the circumference, elastic ball assemblies are clamped in the ball mounting bases, large balls are arranged in the elastic ball assemblies,the filtering device is driven to move up and down through rolling of the large balls, and the filtering piece is filtering cloth. The self-moving material balance filtering device provided by the invention can be automatically changed along with the height change of materials in the material basket; the free floating of the powdery raw material in the extraction process can be prevented; a largeamount of channeling caused by floating and dispersing of materials is avoided, the extraction effect is improved, the product recovery rate is increased, the extraction time is shortened, the production cost is reduced, the filter cloth can conduct primary filtration on powdery raw materials in an extraction medium, and the phenomenon that raw material fine powder enters a filter screen or a filter plate at the top of a material basket is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of fluid extraction, in particular to a self-moving material balance filter device, an extraction kettle containing the device and a use method. Background technique [0002] Supercritical carbon dioxide fluid extraction is an efficient and clean chemical extraction and separation technology, which has the advantages of non-toxic, non-polluting, non-residue, high solubility and easy separation of extraction media. The supercritical carbon dioxide fluid extraction separation process is to use high-density supercritical carbon dioxide to have a greater solubility for the extracted target components, while the solubility of low-density carbon dioxide is significantly reduced and the density of carbon dioxide changes with its pressure and temperature. And change, so as to achieve extraction and separation by changing the pressure and temperature of carbon dioxide. Generally, extraction is performed at higher pr...
