Description

Technical Field

[0001] The utility model belongs to the technical field of finished product collection, and in particular relates to a finished product collection device for supercritical plant extraction. Background Art

[0002] A finished product collection device for supercritical extraction, as the name implies, is a device for collecting and using finished products after supercritical extraction processing. The supercritical in supercritical extraction is a supercritical fluid, which is a state of matter between gas and liquid that is neither gaseous nor liquid. This substance can only exist when its temperature and pressure exceed the critical point. However, the current traditional finished product collection device for supercritical extraction does not have the function of height lifting and lowering, as well as the function of filtering the finished product solvent, so the use effect of the traditional finished product collection device for supercritical extraction is relatively simple.

[0003] Chinese patent CN218188187U discloses a finished product collection device for supercritical extraction, including a bottom plate, a load-bearing plate is arranged at the top center position of the bottom plate, cylinders are arranged at the four corners of the bottom of the load-bearing plate, and the bottom of the cylinders penetrates the bottom plate and is fixedly connected, and the output ends of the four cylinders are fixedly connected with pistons. First, the output end of the cylinder pushes the piston and the push plate up and down, and at the same time, the load-bearing plate and the collection tank connected thereto are lifted up and down, so that the height of the collection tank can be adjusted at will within a certain height according to the required height for subsequent use, and the finished product of the extraction is filtered through the sieve holes above the filter plate, so that the impurities entering the supercritical extraction product during the processing process are filtered, and the filtered supercritical extraction product enters the bottom layer of the collection tank for collection, so as to facilitate subsequent use or other steps.

[0004] The inventors found that although the application achieved filtration of the supercritical extraction product before collection, it only used direct filtration through a filter disc. This filtration method was effective at the beginning, but as time went on, the impurities on the filter disc increased, which easily clogged the filter holes, resulting in a decrease in the overall filtration efficiency. It required manual and timely cleaning, which was very troublesome.

[0005] Therefore, the existing structure and defects are studied and improved, and a finished product collection device for supercritical plant extraction is provided, in order to achieve a more practical purpose. Utility Model Content
