Description

Technical Field

[0001] The invention relates to the field related to bamboo leaf powder production, and in particular to a separation device and a separation method for bamboo leaf powder production. Background Art

[0002] With the increasing awareness of health, consumers' demand for natural and additive-free food additives has increased significantly. Healthy food additives have good application prospects. Bamboo leaf powder, as a natural product derived from nature and rich in multiple active ingredients, has gradually been favored by the market. Bamboo is widely distributed in China and is rich in resources. It is a forestry resource with large resources and very cheap, and it is basically in a state of not being fully developed and utilized. The main raw materials for the production of bamboo leaf powder are the leaves of Dendroclamus farinosus of the Dendrocalamus Nees genus of the Poaceae subfamily and Fαrgesiα Franch.emend.Yi. The main active ingredient in its extract, bamboo leaf flavonoids, has significant antioxidant, anti-inflammatory, antibacterial and other biological activities, as well as significant insecticide and blood sugar regulation biological activities, showing broad application prospects in the fields of food preservation, nutritional supplements and pest control. Therefore, the research and development of the production process of bamboo leaf powder and its key equipment are of great significance to promoting the development of the healthy food industry.

[0003] The production process of bamboo leaf powder usually includes multiple steps such as picking fresh bamboo leaves, washing, drying, crushing, extraction, filtering, concentration, and drying. In the production process of bamboo leaf powder, separation is the key step in extracting effective ingredients.

[0004] However, the centrifugal dehydration method and the extrusion dehydration method in the current separation device each have disadvantages. During centrifugal dehydration, the bamboo leaf fiber is light in weight and is easy to follow the rotation of the drum and block the filter holes, which reduces the dehydration efficiency in the later stage of dehydration. The extrusion dehydration consumes a lot of energy and requires a placement space for the relaxed state of the extrusion structure, which makes the entire structure occupy a large space. The dehydration efficiency of the centrifugal dehydration method and the extrusion dehydration method is not high. Summary of the invention

[0017] Preferably, the outer lower end of the lower discharge pipe is sealed by connecting a sealing cover.

[0018] A separation method comprises the following steps:

[0019] Step 1: Pour the liquid mixed with the crushed bamboo leaves into the material cavity of the cylinder body through the feed hopper and the intermediate drive shaft. Due to the presence of the through slots on the upper side of the cylinder body, the material can directly reach the filtrate cavity; due to the presence of the filtrate holes on the intermediate rotating filtrate cylinder, the liquid directly enters the liquid filtration cavity and flows out through the drain pipe;

[0020] Step 2: The second driving motor drives the third bevel gear to rotate, and the meshing relationship between the third bevel gear and the fourth bevel gear drives the second driving gear to rotate, and the meshing connection relationship between the second driving gear and the second driven gear drives the second driven gear, the external connecting sleeve and the intermediate rotating filtrate cylinder to rotate, and the intermediate rotating filtrate cylinder accelerates the rotation, and the material in the intermediate rotating filtrate cylinder is subjected to centrifugal force and adheres to the inner wall of the intermediate rotating filtrate cylinder, and the liquid is thrown out into the liquid filtration chamber and flows out through the drain pipe;

[0022] Step 4: After a single dehydration is completed, water is delivered through the liquid inlet pipe, the liquid distribution pipe, the annular liquid delivery pipe and the liquid delivery nozzle, the first driving motor drives the first bevel gear to rotate, and the outer protective cylinder is driven to rotate through the meshing action of the first bevel gear and the second bevel gear, and the bamboo leaf powder and crushed materials adhering to the inner wall of the rotating filtrate cylinder are suspended in the water;

[0023] Step 5: Repeat the dehydration step to further dehydrate, complete solid-liquid separation, and collect the filtrate.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The invention has a high-efficiency separation effect. The intermediate rotating filtrate cylinder rotates, and the material in the intermediate rotating filtrate cylinder is attached to the inner wall of the intermediate rotating filtrate cylinder by centrifugal force, and the liquid is thrown out; the intermediate rotating cylinder rotates, and the intermediate spiral strips on the first and second material-dispersing members outside the intermediate rotating cylinder rotate and scrape the excessive bamboo leaf powder and crushed materials adhering to the inner wall of the intermediate rotating filtrate cylinder, and the staggered material-dispersing grooves on each group of two intermediate spiral strips rotate to pull the bamboo leaf powder and crushed materials adhering to the inner wall of the intermediate rotating filtrate cylinder through the force between the fibers of the bamboo leaf powder and crushed materials, so that the bamboo leaf powder and crushed materials temporarily leave the filtrate hole, and make the bamboo leaf powder and crushed materials loose, and the rolling roller will continue to roll the loosened bamboo leaf powder and crushed materials to further dehydrate them. The advantages of centrifugal dehydration and extrusion dehydration are combined. The presence of the first material-dispersing member and the second material-dispersing member makes it difficult for bamboo leaf powder fragments to block the filtrate holes, and the bamboo leaf powder fragments can be pulled apart. The extrusion dehydration method improves the dehydration efficiency without increasing the occupied space, and solves the problems that the centrifugal dehydration method and the extrusion dehydration method each have their own disadvantages. During centrifugal dehydration, the bamboo leaf fiber has a light weight and is easy to follow the rotation of the drum and block the filter holes, which reduces the dehydration efficiency in the later stage of dehydration. The extrusion dehydration consumes a lot of energy and needs to be provided with a placement space for the relaxed state of the extrusion structure, which makes the entire structure occupy a large space. The dehydration efficiency of the centrifugal dehydration method and the extrusion dehydration method is not high.

[0026] 2. In this invention, the unique three-cylinder structure and multi-stage drive system cooperate to realize the entire driving process, so that the materials can be efficiently separated under the action of centrifugal force, spiral scraping and extrusion, greatly improving the separation efficiency.

[0027] 3. In the invention, after a single dehydration is completed, water is delivered through the liquid inlet pipe, the liquid distribution pipe, the annular infusion pipe and the infusion nozzle, the first drive motor drives the first bevel gear to rotate, and the meshing action of the first bevel gear and the second bevel gear drives the outer protective cylinder to rotate, so that the dehydrated bamboo leaf powder can absorb water again, and the effective components can be extracted and separated again; and similarly, this part of the structure and operation process can realize internal cleaning and complete the discharge process. The entire separation process is automatically controlled, which reduces the difficulty of manual operation and improves production efficiency and stability. BRIEF DESCRIPTION OF THE DRAWINGS

A separation method, implemented based on the separation device for producing bamboo leaf powder according to claim 8, characterized in that: The steps include: Step 1: Pour the liquid mixed with the crushed bamboo leaves into the material cavity (29) of the cylinder body (28) through the feed hopper (13) and the intermediate drive shaft (12); due to the presence of the through slot (30) on the upper side of the cylinder body (28), the material can directly reach the filtrate cavity (24); due to the presence of the filtrate hole (23) on the intermediate rotating filtrate cylinder (22), the liquid directly enters the liquid filtration cavity (21) and flows out through the drain pipe (38); Step 2: The second drive motor (7) drives the third bevel gear (8) to rotate, and the meshing relationship between the third bevel gear (8) and the fourth bevel gear (9) drives the second drive gear (11) to rotate, and the meshing connection relationship between the second drive gear (11) and the second driven gear (15) drives the second driven gear (15), the external connection sleeve (16) and the intermediate rotating filtrate cylinder (22) to rotate, and the intermediate rotating filtrate cylinder (22) rotates at an accelerated speed, and the material in the intermediate rotating filtrate cylinder (22) is subjected to centrifugal force and adheres to the inner wall of the intermediate rotating filtrate cylinder (22), and the liquid is thrown out into the liquid filter chamber (21) and flows out through the discharge pipe (38); Step 3: The first driving gear (10) coaxially connected to the second driving gear (11) rotates, and the first driven gear (14) intermediate driving shaft (12) and the intermediate rotating cylinder (27) are driven to rotate through the meshing connection relationship between the first driving gear (10) and the first driven gear (14), and the intermediate rotating cylinder (27) rotates at a reduced speed, and the intermediate spiral strips (36) on the first material dispersing member (33) and the second material dispersing member (34) outside the intermediate rotating cylinder (27) move the intermediate The excessive bamboo leaf powder adhering to the inner wall of the rotating filtrate cylinder (22) is scraped flat by rotation, and the staggered material discharge grooves (37) on each set of two middle spiral strips (36) rotate to pull the bamboo leaf powder adhering to the inner wall of the middle rotating filtrate cylinder (22) through the force between the fibers of the bamboo leaf powder, so that the bamboo leaf powder is temporarily separated from the filtrate hole (23) and the bamboo leaf powder is loosened. The rolling roller (31) continues to roll the loosened bamboo leaf powder to further dehydrate it. Step 4: After a single dehydration is completed, water is delivered through the liquid inlet pipe (17), the liquid distribution pipe (18), the annular liquid delivery pipe (19) and the liquid delivery nozzle (20), the first drive motor (3) drives the first bevel gear (4) to rotate, and the outer protective cylinder (2) is driven to rotate through the meshing action of the first bevel gear (4) and the second bevel gear (5), and the bamboo leaf powder and crushed materials adhered to the inner wall of the intermediate rotating filtrate cylinder (22) are suspended in the water; Step 5: Repeat the dehydration step to further dehydrate, complete solid-liquid separation, and collect the filtrate.
