Description

Technical Field

[0001] The utility model relates to the technical field of Chinese medicinal material processing, in particular to a medicinal residue filtering device for purifying dendrobium. Background Art

[0002] Dendrobium is the fresh or dried stem of the orchid plants Dendrobium annularis, Dendrobium whip, Dendrobium yellow grass, Dendrobium officinale or Dendrobium nobile. It is a commonly used yin-tonifying medicine that has the functions of benefiting the stomach, promoting fluid production, nourishing yin and clearing away heat. Its main chemical components are polysaccharides and alkaloids.

[0003] At present, the process of extracting polysaccharides from dendrobium usually adopts traditional equipment such as common extraction tanks or percolation tanks. Since fresh dendrobium is in strips, while processed dendrobium is in large curly particles, the direct extraction effect is very poor. Therefore, it is necessary to extract the processed and dried dendrobium to improve the extraction rate of effective ingredients. After extraction, the extract and the residue are filtered and separated. However, during filtration, due to the fiber characteristics of the residue, a large amount of extract will still be infiltrated in it, which is very wasteful.

[0004] This case was created to solve the above problems. Utility Model Content

[0020] The utility model is further described in detail below through the drawings and embodiments.

[0021] The utility model provides a device for filtering medicinal residues for purifying dendrobium, such as Figure 1-4 As shown, it includes a bracket 1, a tank body 2 is arranged between the bracket 1, a filter plate 3 and a pressing plate 4 which are slidably connected to the inner wall of the tank body 2 are arranged inside the tank body 2, the pressing plate 4 is above the filter plate 3, a feed port 5 and a slag discharge port 6 are opened on the side wall of the tank body 2, the feed port 5 and the slag discharge port 6 are located at a height between the filter plate 3 and the pressing plate 4, and a rotating shaft 7 is connected to the outside of the bracket 1. When filtering, a mixture of medicinal residue and extract is put into the tank body 2 from the feed port 5, and the internal pressing plate 4 is pressed down to cooperate with the filter plate 3 for filtering. After the filtering is completed, the slag discharge port 6 is opened, and the bracket 1 and the tank body 2 are turned over under the action of the rotating shaft 7 to pour out the medicinal residue from the slag discharge port 6.
