Abstract

This application provides a membrane separation high-efficiency Dendrobium officinale fresh extraction and purification device, relating to the field of Dendrobium officinale fresh extraction and purification technology. It includes an enzymatic hydrolysis tank, with a transmission pipe fixedly installed on the right side. A high-efficiency Dendrobium officinale pulverizing component is configured, and a second motor drives a movable shaft and a movable push rod to rotate. The rotation of the movable push rod causes a spring to drive a limit slide rod and a cutting blade to descend and cut the Dendrobium officinale.

This pulverization method results in better pulverization of the Dendrobium officinale, and during the pulverization and cutting process, the Dendrobium officinale is only chopped without being squeezed, preventing juice leakage and resulting in a clear and non-turbid enzymatic hydrolysate.

Description

Technical Field

[0001] This utility model relates to the field of Dendrobium officinale fresh extraction and purification technology, and in particular to a membrane separation high-efficiency Dendrobium officinale fresh extraction and purification device. Background Technology

[0002] Dendrobium is one of the largest genera in the Orchidaceae family, with over 1,500 species widely distributed in tropical and subtropical regions of Asia, Europe, and Oceania. my country has approximately 80 species, mainly distributed in Southwest, East, and South China. In traditional Chinese medicine, the fresh or dried stems of many Dendrobium species are harvested for medicinal use and are collectively called Dendrobium. Dendrobium officinale (iron-skin Dendrobium) is a traditional and precious Chinese medicinal herb. Modern TCM theory believes that Dendrobium officinale has the effects of strengthening the spleen and stomach, nourishing yin and tonifying the kidneys, moistening the lungs and promoting fluid production, and is used to treat chronic atrophic gastritis, hypertension, diabetes, and for anti-tumor and anti-aging purposes. For decades, scholars from China and abroad have conducted extensive research on the chemical composition and pharmacological effects of Dendrobium, discovering that its chemical components are diverse, with its main effective components being Dendrobium polysaccharides and alkaloids. As people's understanding of the effects of polysaccharides increases, it has been discovered that Dendrobium officinale polysaccharides have strong anti-tumor and antioxidant biological activities. The separation and purification process of Dendrobium officinale polysaccharides requires multiple steps, including raw material crushing, sieving, defatting, solvent extraction, enzymatic extraction, water extraction, filtration, concentration, alcohol precipitation, separation, freeze drying, and protein removal.

[0003] Existing Dendrobium officinale fresh extraction purification devices require the use of a pulverizer to crush the fresh Dendrobium officinale stems. However, this crushing method results in the extraction of a solution from the fresh Dendrobium officinale stems, which is turbid due to the presence of solids and a large amount of Dendrobium officinale fiber residue. This is not conducive to subsequent filtration and purification by the membrane separation unit. Therefore, we propose a membrane separation high-efficiency Dendrobium officinale fresh extraction purification device. Utility Model Content

[0034] In this embodiment, the Dendrobium officinale feeding, purification, separation and extraction component 2 includes a mounting frame 31, a reinforcing rib 32, a third motor 33, a second drive shaft 34 and an auxiliary shaft 35. The mounting frame 31 is fixedly installed on the top of the enzymatic hydrolysis tank 3. One end of the reinforcing rib 32 is fixedly installed on the left side of the enzymatic hydrolysis tank 3, and the other end of the reinforcing rib 32 is fixedly installed on the bottom of the mounting frame 31. The third motor 33 is fixedly installed on the rear side of the mounting frame 31. The second drive shaft 34 is fixedly installed on the output end of the third motor 33.

[0035] In this embodiment, the Dendrobium officinale feeding, purification, separation, and extraction component 2 further includes a synchronous wheel 36, a synchronous belt 37, a sealing baffle 38, and a Dendrobium officinale placement support plate 39. The synchronous wheel 36 is fixedly installed on the outside of the second drive shaft 34 and the auxiliary shaft 35. The synchronous belt 37 is tensioned and sleeved on the outside of the synchronous wheel 36. The sealing baffle 38 is fixedly installed on the outside of the second drive shaft 34. The Dendrobium officinale placement support plate 39 is fixedly installed on the outside of the auxiliary shaft 35. The sealing baffle 38 is in contact with the top of the enzymatic hydrolysis tank 3. During the crushing and cutting process, the Dendrobium officinale is only crushed and is not squeezed. If juice overflows, the third motor 33 can be controlled to drive the second drive shaft 34 to rotate. After the second drive shaft 34 rotates, it can drive the auxiliary shaft 35 to rotate through the synchronous pulley 36 and the synchronous belt 37. The synchronous rotation of the second drive shaft 34 and the auxiliary shaft 35 can drive the dendrobium placement support plate 39 and the sealing baffle 38 to rotate synchronously. After the sealing baffle 38 rotates, the enzymatic hydrolysis tank 3 can be opened. After the dendrobium placement support plate 39 rotates, the chopped dendrobium can fall into the interior of the enzymatic hydrolysis tank 3 for enzymatic hydrolysis and extraction, which can make the enzymatic hydrolysate clearer and less turbid.

[0036] In this embodiment, guide grooves are provided on one side of both the mobile control frame 22 and the fixed box 17, and the guide rod 15 and the limiting slide rod 18 fit into the corresponding guide grooves. The guide grooves can make the mobile control frame 22 and the limiting slide rod 18 more stable during movement, and can prevent the cutting blade 19 from deviating during cutting.

[0037] In this embodiment, the top of the Dendrobium officinale placement support plate 39 is provided with a wear-resistant coating, and the bottom of the sealing baffle 38 is provided with a sealing ring. The wear-resistant coating allows the Dendrobium officinale placement support plate 39 to be supported without being damaged after the Dendrobium officinale above is cut. The sealing ring allows the sealing baffle 38 to seal the enzymatic hydrolysis tank 3.

[0038] The specific operation involves placing the Dendrobium officinale to be chopped on the Dendrobium officinale support plate 39, and controlling the electric telescopic rod 24 to move the movable push rod 27 to push the movable control frame 22. The movable control frame 22 can move the connecting block 23, the connecting rope 21, and the limiting slide rod 18, allowing the limiting slide rod 18 to drive the cutting blade 19 to rise. The fixed box 17 can guide and limit the limiting slide rod 18, and the guide rod 15 can limit the movable control frame 22. At this time, the second motor 25 can be controlled to drive the movable shaft 26. The movable push rod 27 rotates, causing the spring 20 to drive the limit slide rod 18 and the cutting blade 19 to descend and cut the Dendrobium. The spring 20 also helps the cutting blade 19 to cushion and absorb shock during cutting, preventing damage or breakage. The first motor 11 drives the first drive shaft 12 and mounting plate 13 to rotate, allowing the position of the cutting blade 19 to be adjusted. This allows the cutting blade 19 to cut the Dendrobium at multiple angles and times, resulting in better pulverization. During pulverization and cutting, the Dendrobium is only chopped and not squeezed, preventing juice leakage. At this point, the third motor 33 drives the second drive shaft 34 to rotate. The rotation of the second drive shaft 34, through the synchronous pulley 36 and synchronous belt 37, drives the auxiliary shaft 35 to rotate. The synchronous rotation of the second drive shaft 34 and auxiliary shaft 35 causes the Dendrobium placement support plate 39 and sealing baffle 38 to rotate synchronously. The rotation of the sealing baffle 38 allows the enzymatic hydrolysis tank 3 to... When the Dendrobium officinale is turned on, the support plate 39 rotates, allowing the chopped Dendrobium officinale to fall into the enzymatic hydrolysis tank 3 for enzymatic extraction. This process results in a clearer and less turbid hydrolysate. After extraction, the third motor 33 rotates in the opposite direction, allowing the sealing baffle 38 to seal and protect the enzymatic hydrolysis tank 3. After enzymatic hydrolysis, the extract can pass through the filter box 5. The ceramic membrane 6, polysulfone hollow fiber membrane 7, and spiral wound nanofiltration membrane 8 inside the filter box 5 can separate solid impurities from the extract, removing residues and separating polysaccharides of different molecular weights.

[0039] It should be noted that although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
