Description

A special extractor for plant extract

technical field

The invention belongs to the field of chemical instruments, in particular to a special extractor for plant extracts.

Background technique

Plants are rich in nutrients and medicinal ingredients, especially plant extracts can be applied to many industries, such as medicine, cosmetics, food, scientific research, etc., and their attention is increasing day by day, and special beneficial ingredients also have extremely high commercial and scientific research value.

There are devices for absorbing liquid in the prior art. For example, the Chinese patent with publication number CN204602143U discloses a supernatant liquid extractor, which includes a pumping head, a slag blocking plate at the bottom of the pumping head, and a slag blocking plate below the slag blocking plate. The stabilizing bar, the pumping head is provided with a plurality of liquid inlet holes near the slag blocking plate, and the pumping head is connected to the pumping pipeline for transporting the supernatant. Another example is that the Chinese patent with publication number CN204239351U discloses a liquid extractor. The liquid extractor includes a straight cylinder body, a liquid outlet pipe, a piston, a piston rod, an upper end cover and an exhaust plug. A second one-way valve and a first one-way valve are respectively arranged at the bottom end of the straight cylinder body and the center of the piston. The upper end cover of the main body is provided with a vent hole and a vent plug matching the vent hole. The siphon phenomenon can be quickly established by driving the piston up and down through the pull rod, and the liquid in the liquid storage container is sucked into the straight cylinder and discharged from the side of the straight cylinder. The outlet side pipe on the wall is discharged, and the siphon phenomenon can be quickly relieved by opening the exhaust plug. In the above process, it can be realized by pulling the pull rod several times. The operation is flexible and convenient without limitation. The liquid in the pipe can flow out quickly, and the liquid in the straight body can be discharged through the vent hole, and there will be no residual liquid in the straight body, so that there will be no waste of resources.

However, the above instruments are relatively complicated and cannot be applied to plant extracts. Plant extracts are generally subjected to superfine grinding, filtration or centrifugation to obtain supernatants, but often there are still plant residues in the obtained supernatants, which need to be further removed, and there is no suitable test equipment in the existing test equipment. Advanced instruments can achieve extraction and filtration, so it is urgent to design corresponding instruments to meet the requirements of the test.

Utility model content

The purpose of the utility model is to provide a plant extract extractor which can realize extracting and filtering at the same time in view of the deficiencies in the prior art.

Technical solution: The utility model provides a plant extract extractor, which is composed of an extraction part 1 and a filter part 4. One end of the extraction part 1 is an inlet and an outlet, and the other end is a screw joint. Through the screw joint and the filter part, 4 are connected, and the middle part of the extraction part is provided with a filter layer 3; the extraction part is composed of an outer tube and a piston 2 located in the outer tube, the inner end of the piston 2 is provided with a sealing head 21, and the outer end is provided with a handle 22.

The filter layer is a composite filter layer. The composite filter layer is composed of two layers of filter materials. The two layers of filter materials, one layer is water-based PES, and the other layer is organic-based nylon 66. The thickness ratio of the two layers of filter materials is 1:1.2-2.

The lower end of the extracting part is provided with a screw interface matched with the screw joint. The extraction part and the filter part are detachably connected.

Beneficial effects: the utility model is simple in structure and easy to operate.

With the special extractor provided by the utility model, after the extraction liquid is first extracted, the piston is driven by applying pressure, and the extraction liquid passes through the composite filter membrane successively, and the residual substances in the extraction liquid whose particle diameter is larger than the average pore diameter of the surface layer are intercepted, Only the supernatant is allowed to pass through, so that the extract is purified, which provides a very effective and necessary guarantee for the subsequent extraction, purification and separation of active ingredients.

In addition, the utility model is designed with a matching screw interface, which solves the trouble of pushing the piston with one hand and holding the interface with the other hand during the original operation, which is convenient, practical and effective.

detailed description:

The utility model is composed of an extracting part 1 and a filtering part 4. One end of the extracting part 1 is an inlet and outlet, and the other end is a screw joint, which is connected with the filtering part 4 through the screw joint. The middle part of the extracting part is provided with a filter layer 3; The extraction part is composed of an outer tube and a piston 2 inside the outer tube. The inner end of the piston 2 is provided with a sealing head 21 , and the outer end is provided with a handle 22 .

The filter layer is a composite filter layer. The composite filter layer is composed of two layers of filter materials. The two layers of filter materials, one layer is water-based PES, and the other layer is organic-based nylon 66. The thickness ratio of the two layers of filter materials is 1:1.2-2.

The lower end of the extracting part is provided with a screw interface matched with the screw joint. The extraction part and the filter part are detachably connected.

Take jasmine flower extract as an example. The raw material is jasmine flower, which is extracted with a certain concentration of ethanol aqueous solution, submerged, and extracted with a microwave with a certain power and a certain time. Then use a suction filter to carry out suction filtration, and the filtrate is taken out, which is light yellow-green, slightly turbid, and has a small amount of white flocs visible to the naked eye. Remove the extraction part, absorb a certain amount of filtrate, then install the extraction part, and squeeze the filtrate into another clean beaker. The concentration of the extract is slightly deeper, dark yellow-green, clear and free of impurities. The extract is filtered.
