Description

Technical Field

[0001] The invention relates to the technical field of agricultural product processing, and in particular to a device for drying and powdering a roxburghii extract. Background Art

[0002] Rosa roxburghii extract is a natural plant extract extracted from Rosa roxburghii fruit. The main components of Rosa roxburghii extract include vitamin C, flavonoids, polyphenols, pectin, dietary fiber, minerals and amino acids. However, the extract in the liquid state contains water, which is easy to breed microorganisms and cause corruption and deterioration. Moreover, the extract in the liquid state has a large volume and a heavy weight. If the packaging is damaged during transportation, leakage and pollution will occur. Therefore, in order to facilitate storage and reduce transportation costs, the Rosa roxburghii extract is dried and ground to reduce its volume and weight. Now, after the Rosa roxburghii extract is dried, the Rosa roxburghii extract is obtained, and then the Rosa roxburghii extract is put into a grinding device for grinding to reach the target fineness. However, during the drying process, the Rosa roxburghii extract is easily attached to the drying equipment, resulting in the loss of the Rosa roxburghii extract. At the same time, after the drying is completed, the sea buckthorn extract attached to the drying equipment needs to be cleaned regularly to prevent the attached sea buckthorn extract from affecting the quality of the subsequent sea buckthorn extract after drying. At the same time, when cleaning the dried sea buckthorn extract, the drying equipment is in a shutdown state, which affects the continuity of drying and further reduces the drying and grinding efficiency of the sea buckthorn liquid. Summary of the invention

[0003] The invention aims to provide a device for drying and powdering a roxburghii extract, so as to solve the problem that part of the roxburghii extract adheres to the drying device after the roxburghii extract is dried, thus affecting the drying and powdering efficiency.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a device for drying and powdering a roxburghii extract, comprising a box body and a drying mechanism, wherein the bottom of the box body is made of a toothed disc for grinding, the top of the box body is provided with an exhaust hole, the top of the box body is also fixedly connected with a motor, the output shaft of the motor vertically passes through the box body downward and is located in the box body, the bottom end of the output shaft of the motor is coaxially fixedly connected with a threaded rod, the top and bottom ends of the threaded rod are both cylindrically arranged and the length is the same as the thickness of a scraper, and the bottom end of the threaded rod is fixedly connected with a grinding rod for grinding in cooperation with the toothed disc; a scraper is slidably connected in the box body, a threaded hole used in cooperation with the threaded rod is provided at the center of the scraper, the edge of the scraper is in sliding contact with the inner wall of the box body, and a plurality of air holes for water vapor to pass through are evenly distributed on the scraper;

[0005] The drying mechanism includes a heater and a liquid tank. The heater is installed outside the box. The air outlet of the heater is connected to an air duct. The air outlet end of the air duct passes through the box and is located on the same vertical plane as the inner wall of the box, and the air outlet end of the air duct is located above the grinding rod; the liquid tank is fixedly connected to the outside of the box, and the bottom of the liquid tank is connected to a liquid pipe. One end of the liquid pipe away from the liquid tank passes through the box and is located on the same vertical plane as the inner wall of the box, and an atomizing nozzle is provided at this end of the liquid pipe; the top of the liquid tank is connected to an air pipe, and one end of the air pipe away from the liquid tank is connected to a pressure pump.

[0006] The working principle of the present invention is as follows: a front scraper is located at the inner top of a box body, and when in use, a roxburgh extract to be dried and ground is poured into a liquid tank, and then a heater is started. When the heater is running, hot air is injected into the box body through an air duct to heat the inside of the box body, and at this time, a pressure pump is started. When the pressure pump is running, air is injected into the liquid tank through an air pipe to increase the pressure inside the liquid tank, and the roxburgh extract in the liquid tank is pressed into the liquid pipe under the action of pressure, and then sprayed into the box body in an atomized state through an atomizing nozzle, and the roxburgh extract in the box body is heated so that the water contained therein is quickly evaporated into water vapor, and then separated from the roxburgh extract, and at this time, the water vapor flows upward in the box body, passes through air holes and exhaust holes and flows out of the box body. And the dried roxburgh extract becomes roxburgh extract, roxburgh extract falls on the toothed disk at the bottom of the casing under gravity or adheres to the inner wall of the casing, after a period of drying, the motor is started, the output shaft drives the threaded rod to rotate when the motor is running, the threaded rod drives the grinding rod to rotate on the toothed disk when the threaded rod rotates, and the roxburgh extract falling on the toothed disk is ground to make it powdery when the grinding rod rotates. Simultaneously when the threaded rod rotates, the threaded rod can push the scraper to move downward, because the edge of the scraper is in sliding contact with the inner wall of the casing, so when the scraper moves downward, the roxburgh extract attached to the inner wall of the casing and the threaded rod surface can be scraped off, fall on the toothed disk and grind, when the scraper moves to the bottom end of the threaded rod, the lower surface of the scraper contacts the upper surface of the grinding rod, so when the grinding rod rotates, the roxburgh extract attached to the lower surface of the scraper can be scraped off, and the bottom end of the threaded rod is a cylindrical arrangement, so when the scraper moves to the cylindrical section, the threaded rod can no longer push the scraper to continue to move. After the lower surface of the scraper is cleaned, start the motor in reverse. At this time, the output shaft of the motor rotates in the reverse direction. When the output shaft of the motor rotates in the reverse direction, the threaded rod rotates in the reverse direction. The reverse rotation of the threaded rod drives the scraper to move upward until the scraper moves to the top of the box.

[0007] Beneficial effects of the present invention:

[0008] 1. This scheme is adopted. After the roxburghii extract is dried, the motor drives the spiral rod to rotate, thereby driving the scraper to move downward. During the movement of the scraper, the roxburghii extract obtained by drying attached to the inside of the box is scraped off, so that it falls onto the toothed disc and is ground by the grinding rod and the toothed disc. After the scraper moves to the bottom of the box, the lower surface of the scraper contacts the upper surface of the grinding rod, so that the roxburghii extract attached to the lower surface of the scraper is scraped off when the grinding rod rotates, so that the drying efficiency of the roxburghii extract is ensured and production is guaranteed without stopping the machine to clean the drying equipment.

[0009] 2. The drying and grinding of the roxburghii extract are carried out simultaneously, and there is no need to manually transport the dried roxburghii extract to the grinding equipment, which saves manpower and transportation time, reduces processing steps, saves production costs, and improves production efficiency.

[0010] 3. In this scheme, the roxburghii extract is directly ground into powder after being dried without being transported, thus reducing the transportation link and reducing the chance of the dried roxburghii extract contacting the external environment, thus reducing the risk of contamination and effectively ensuring the quality of the dried roxburghii extract.

[0011] Further, the toothed disc is a toothed disc made of a filter screen plate. The purpose is that when the toothed disc cooperates with the grinding rod for grinding, when the fineness of the powder is appropriate, the ground roxburghii extract falls below the box through the gap of the toothed disc.

[0012] Further, the outer bottom of the box is fixedly connected with a collecting hopper, which is located directly below the toothed disc. The purpose is to facilitate the collection of the roxburghii extract after being ground into powder into the collecting hopper through this arrangement, so as to facilitate collection.

[0013] Further, the edges of the two opposite ends of the scraper are provided with notches, and magnets are fixedly embedded in the notches. The two opposite sides of the outer wall of the box are fixedly connected with a box body, and the two box bodies are located at the same horizontal height as the cylindrical section at the bottom end of the threaded rod. A permanent magnet that slides in the vertical direction is provided in the box body, and the permanent magnet and the magnet attract each other. The lower surface of the permanent magnet is fixedly connected with a spring made of rubber, and the bottom end of the spring is fixedly connected to the inner bottom of the box body. Its purpose is that through this arrangement, when the scraper moves down to the bottom end position of the threaded rod, the magnet and the permanent magnet attract each other, and then when the threaded rod rotates to make the scraper continue to move down, the magnet drives the permanent magnet to move downward in the box body through suction, and the spring is in a compressed state at this time. When the motor rotates in the opposite direction, the threaded rod no longer continues to push the scraper downward, and the permanent magnet is pushed upward in the box body under the elastic force of the spring. When the permanent magnet moves upward, the scraper is driven by the magnet to move upward and contact the bottom end of the thread of the threaded rod, so that when the threaded rod rotates in the opposite direction, the scraper can be better engaged, and then the scraper can be smoothly moved up on the threaded rod.

[0014] Furthermore, the box is double-layered, and electric heating wires are evenly distributed in the interlayer of the box. The purpose is that when the temperature inside the box does not meet the drying requirements, the electric heating wires can be turned on to heat the inside of the box to speed up the heating speed.

The lower surface of the grinding rod 11 is a serrated shape used in conjunction with the toothed disc 13, and the upper surface of the grinding rod 11 is conical; a scraper 5 is slidably connected to the box body 3, and a threaded rod 17 is provided at the center of the scraper 5. The threaded holes used in conjunction with the threaded rod 17, the edge of the scraper 5 is in sliding contact with the inner wall of the box body 3, and a number of air holes 6 for the passage of water vapor are evenly distributed on the scraper 5. The outer bottom of the box body 3 is fixedly connected to a collecting hopper 12, and the collecting hopper 12 is located directly below the toothed disc 13. Notches are provided at the edges of the opposite ends of the scraper 5, and magnets 4 are fixedly embedded in the notches. The opposite sides of the outer wall of the box body 3 are fixedly connected to a box body 14, and the two box bodies 14 are respectively located on the same vertical plane with the two magnets 4, and the two box bodies 14 and the cylindrical section at the bottom of the threaded rod 17 are at the same horizontal height. A permanent magnet 16 sliding in the vertical direction is provided in the box body 14, and the permanent magnet 16 and the magnet 4 attract each other. A spring 15 made of rubber is fixedly connected to the lower surface of the permanent magnet 16, and the bottom end of the spring 15 is fixedly connected to the inner bottom of the box body 14.

[0022] The drying mechanism includes a heater and a liquid tank 7. The heater is installed outside the box body 3. The air outlet of the heater is connected to an air duct 10. The air outlet end of the air duct 10 passes through the box body 3 and is located on the same vertical plane as the inner wall of the box body 3, and the air outlet end of the air duct 10 is located above the grinding rod 11; the liquid tank 7 is fixedly connected to the outside of the box body 3, and the bottom of the liquid tank 7 is connected to a liquid pipe 8. The end of the liquid pipe 8 away from the liquid tank 7 passes through the box body 3 and is located on the same vertical plane as the inner wall of the box body 3. The end of the liquid pipe 8 is provided with an atomizing nozzle 9; the top of the liquid tank 7 is connected to an air pipe, and the end of the air pipe away from the liquid tank 7 is connected to a pressure pump.

[0023] The specific implementation process is as follows:

[0024] Before use, the scraper 5 is located at the inner top of the box body 3. When in use, the roxburghii extract that needs to be dried and ground is poured into the liquid tank 7, and then the heater is started. When the heater is running, hot air is injected into the box body 3 through the air duct 10 to heat the inside of the box body 3. At this time, the pressure pump is started. When the pressure pump is running, air is injected into the liquid tank 7 through the air pipe to increase the pressure inside the liquid tank 7. The roxburghii extract in the liquid tank 7 is pressed into the liquid pipe 8 under the action of pressure, and then sprayed into the box body 3 in an atomized state through the atomizing nozzle 9. The roxburghii extract entering the box body 3 is heated so that the water contained in it is quickly evaporated into water vapor, and then separated from the roxburghii extract. At this time, the water vapor flows upward in the box body 3, passes through the air hole 6 and the exhaust hole 2 and flows out of the box body 3. The dried roxburgh extract becomes roxburgh extract, which falls onto the toothed disc 13 at the bottom of the box body 3 or adheres to the inner wall of the box body 3 under the action of gravity. After drying for a period of time, the motor 1 is started. When the motor 1 is running, the output shaft drives the threaded rod 17 to rotate. When the threaded rod 17 rotates, the grinding rod 11 is driven to rotate on the toothed disc 13. When the grinding rod 11 rotates, the roxburgh extract that falls onto the toothed disc 13 is ground into powder. At the same time, when the threaded rod 17 rotates, the threaded rod 17 will push the scraper 5 to move downward. Since the edge of the scraper 5 is in sliding contact with the inner wall of the casing 3, the roxburghii extract attached to the inner wall of the casing 3 and the surface of the threaded rod 17 will be scraped off when the scraper 5 moves downward, and the roxburghii extract attached to the surface of the threaded rod 17 will fall onto the toothed disc 13 for grinding. When the scraper 5 moves to the bottom end of the threaded rod 17, the lower surface of the scraper 5 contacts the upper surface of the grinding rod 11, so when the grinding rod 11 rotates, the roxburghii extract attached to the lower surface of the scraper 5 will be scraped off, and the bottom end of the threaded rod 17 is cylindrical, so when the scraper 5 moves to the cylindrical section, the threaded rod 17 will no longer be able to push the scraper 5 to continue to move. After the lower surface of the scraper 5 is cleaned, the motor 1 is reversely started, and the output shaft of the motor 1 rotates in the reverse direction. When the output shaft of the motor 1 rotates in the reverse direction, the threaded rod 17 is driven to rotate in the reverse direction, and the reverse rotation of the threaded rod 17 drives the scraper 5 to move upward until the scraper 5 moves to the top of the casing 3.

[0025] When the scraper 5 moves down to the bottom end of the threaded rod 17, the magnet 4 and the permanent magnet 16 attract each other, and then when the threaded rod 17 rotates to make the scraper 5 continue to move down, the magnet 4 drives the permanent magnet 16 to move downward in the box body 14 through suction. At this time, the spring 15 is in a compressed state. When the motor 1 rotates in the opposite direction, the threaded rod 17 no longer continues to push the scraper 5 downward. Under the elastic force of the spring 15, the permanent magnet 16 is pushed to move upward in the box body 14. When the permanent magnet 16 moves upward, it drives the scraper 5 to move upward through the magnet 4 and contact with the bottom end of the thread of the threaded rod 17. In this way, when the threaded rod 17 rotates in the opposite direction, the scraper 5 can be better engaged, and the scraper 5 can move up on the threaded rod 17 smoothly.
