Description
Technical Field
[0001] This invention relates to the field of agricultural product processing technology, specifically to a device for drying prickly pear extract into powder. Background Technology
[0002] Prickly pear extract is a natural plant extract obtained from the fruit of the prickly pear. Its main components include vitamin C, flavonoids, polyphenols, pectin, dietary fiber, minerals, and amino acids. However, the liquid extract contains water, making it susceptible to microbial growth and spoilage. Furthermore, its large volume and weight during transport increase the risk of leakage and contamination if the packaging is damaged. Therefore, to facilitate preservation and reduce transportation costs, the prickly pear extract is dried and ground into powder to reduce its volume and weight. The prickly pear extract is dried to obtain the final powder, which is then ground to achieve the desired fineness. However, during the drying process, the extract tends to adhere to the drying equipment, resulting in some loss. Meanwhile, after drying, the prickly pear extract adhering to the drying equipment needs to be cleaned regularly to avoid affecting the quality of the prickly pear extract after subsequent drying. At the same time, the drying equipment is shut down when cleaning the dried prickly pear extract, which affects the continuity of drying and will reduce the efficiency of drying and grinding the prickly pear liquid. Summary of the Invention
[0003] The present invention aims to provide a device for drying prickly pear extract into powder, in order to solve the problem that some extracts adhere to the inside of the drying equipment after drying, which affects the efficiency of drying and grinding.
[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a device for drying prickly pear extract into powder, comprising a box and a drying mechanism. The bottom of the box is made of a toothed disc for grinding, and the top of the box is provided with an exhaust hole. A motor is also fixedly connected to the top of the box. The output shaft of the motor passes vertically downward through the box and is located inside the box. A threaded rod is coaxially fixedly connected to the bottom end of the output shaft of the motor. The top and bottom ends of the threaded rod are cylindrical and the length is the same as the thickness of the scraper. A grinding rod for grinding with the toothed disc is fixedly connected to the bottom end of the threaded rod. A scraper is slidably connected inside the box. A threaded hole for cooperating with the threaded rod is provided at the center of the scraper. The edge of the scraper slides in contact with the inner wall of the box. A number 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 housing, and an air duct is connected to the air outlet of the heater. The air outlet of the air duct passes through the housing and is located on the same vertical plane as the inner wall of the housing, and the air outlet of the air duct is located above the grinding rod. The liquid tank is fixedly connected to the housing. A liquid pipe is connected to the bottom of the liquid tank. The end of the liquid pipe away from the liquid tank passes through the housing and is located on the same vertical plane as the inner wall of the housing, and an atomizing nozzle is provided at this end of the liquid pipe. An air pipe is connected to the top of the liquid tank, and a pressure pump is connected to the end of the air pipe away from the liquid tank.
[0006] Working principle of this invention: Before use, the scraper is located at the top inside the chamber. When using, the prickly pear extract that needs to be dried and ground is poured into the liquid tank. Then, the heater is turned on. When the heater is running, hot air is injected into the chamber through the air pipe to heat the inside of the chamber. At the same time, the pressure pump is turned on. When the pressure pump is running, air is injected into the liquid tank through the air pipe to increase the pressure inside the liquid tank. Under the pressure, the prickly pear extract in the liquid tank is forced into the liquid pipe and then sprayed into the chamber in an atomized form through the atomizing nozzle. The prickly pear extract that enters the chamber is heated, causing the water it contains to evaporate quickly into water vapor, which is then separated from the prickly pear extract. At this time, the water vapor flows upward inside the chamber and flows out of the chamber through the air hole and exhaust hole. The dried prickly pear extract becomes prickly pear extract. Under gravity, the prickly pear extract falls onto the toothed disc at the bottom of the chamber or adheres to the inner wall of the chamber. After drying for a period of time, the motor is started. When the motor runs, it drives the threaded rod to rotate through the output shaft. As the threaded rod rotates, it drives the grinding rod to rotate on the toothed disc. When the grinding rod rotates, it grinds the prickly pear extract that has fallen onto the toothed disc into powder. At the same time, as the threaded rod rotates, it pushes the scraper downward. Because the edge of the scraper slides in contact with the inner wall of the chamber, the scraper scrapes off the prickly pear extract adhering to the inner wall of the chamber and the surface of the threaded rod as it moves downward, and the extract falls onto the toothed disc for grinding. When the scraper moves to the bottom of the threaded rod, the lower surface of the scraper contacts the upper surface of the grinding rod. Therefore, when the grinding rod rotates, it scrapes off the prickly pear extract adhering to the lower surface of the scraper. Since the bottom of the threaded rod is cylindrical, the threaded rod can no longer push the scraper to move further after it moves to the cylindrical section. 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 reverse. When the output shaft of the motor rotates in reverse, it drives the threaded rod to rotate in reverse. The reverse rotation of the threaded rod drives the scraper to move upward until the scraper moves to the top of the box.
[0007] The beneficial effects of this invention are:
[0008] 1. Using this method, after the prickly pear extract is dried, a motor drives a screw rod to rotate, which in turn moves a scraper downwards. During the scraper's movement, the dried prickly pear extract adhering to the inside of the chamber is scraped off and falls onto a toothed disc, where it is ground by the grinding rod and the toothed disc. After the scraper moves to the bottom of the chamber, its lower surface contacts the upper surface of the grinding rod. Thus, as the grinding rod rotates, it scrapes off the prickly pear extract adhering to the lower surface of the scraper. This eliminates the need to stop the drying equipment for cleaning, ensuring the drying efficiency of the prickly pear extract and guaranteeing production.
[0009] 2. The drying and grinding of prickly pear extract are carried out simultaneously, eliminating the need for manual transfer of the dried prickly pear extract to the grinding equipment. This saves manpower and transfer time, reduces processing steps, saves production costs, and improves production efficiency.
[0010] 3. In this method, the prickly pear extract is dried and then directly ground into powder without transportation. This reduces the transportation links and the chance of the dried prickly pear extract coming into contact with the external environment, thus reducing the risk of contamination and effectively ensuring the quality of the dried prickly pear extract.
[0011] Furthermore, the toothed disc is a toothed disc made of a filter screen. The purpose of this is that, when the toothed disc and the grinding rod are engaged in grinding, once the powder is of suitable fineness, the ground prickly pear extract will fall through the gaps in the toothed disc to the bottom of the housing.
[0012] Furthermore, a collection hopper is fixedly connected to the bottom of the casing, and the collection hopper is located directly below the toothed disc. The purpose of this arrangement is to facilitate the collection of the ground prickly pear extract into the collection hopper for easy collection.
[0013] Furthermore, notches are provided at the edges of opposite ends of the scraper, and magnets are fixedly embedded in the notches. Boxes are fixedly connected to opposite sides of the outer wall of the housing. The two boxes are at the same horizontal level as the cylindrical section at the bottom of the threaded rod. A vertically sliding permanent magnet is provided inside each box, attracting the permanent magnets. A rubber spring is fixedly connected to the lower surface of the permanent magnet, and the bottom end of the spring is fixedly connected to the inner bottom of the box. The purpose of this arrangement is that when the scraper moves down to the bottom of the threaded rod, the magnets attract each other. Then, when the threaded rod rotates, causing the scraper to continue moving downwards, the magnets, through attraction, drive the permanent magnets downwards within the box. At this time, the spring is compressed. When the motor rotates in the opposite direction, the threaded rod no longer continuously pushes the scraper downwards. Under the elastic force of the spring, the permanent magnets are pushed upwards within the box. When the permanent magnets move upwards, they drive the scraper upwards to contact the bottom end of the thread on the threaded rod. This allows the scraper to better engage when the threaded rod rotates in the opposite direction, thus allowing the scraper to move smoothly upwards on the threaded rod.
[0014] Furthermore, the chamber is double-layered, with heating wires evenly distributed within the interlayer. The purpose of this design is to allow the heating wires to be activated to heat the interior of the chamber and accelerate the temperature rise when the internal temperature is insufficient for drying.

[0020] The basic implementation examples are as follows: Figure 1 Appendix Figure 2 and attached Figure 3 As shown:
[0021] A device for drying prickly pear extract into powder includes a housing 3 and a drying mechanism. The housing 3 is double-layered, with heating wires evenly distributed in the interlayer. The bottom of the housing 3 is made of a grinding disc 13, which is a filter screen. The top of the housing 3 has an exhaust hole 2. A motor 1 is also fixedly connected to the top of the housing 3. The output shaft of the motor 1 passes vertically downward through the housing 3 and is located inside the housing 3. A threaded rod 17 is coaxially fixedly connected to the bottom end of the output shaft of the motor 1. The top and bottom ends of the threaded rod 17 are cylindrical and the length is the same as the thickness of the scraper 5. A horizontally arranged grinding rod 11 is fixedly connected to the bottom end of the threaded rod 17. The lower surface of the grinding rod 11 is serrated to cooperate with the grinding disc 13, and the upper surface of the grinding rod 11 is conical. A scraper 5 is slidably connected inside the housing 3. The center of the scraper 5 is provided with The threaded hole used in conjunction with the threaded rod 17 has a sliding contact between the edge of the scraper 5 and the inner wall of the box 3. The scraper 5 has several air holes 6 evenly distributed on it for water vapor to pass through. The outer bottom of the box 3 is fixedly connected to a hopper 12, which is located directly below the toothed disc 13. The edges of the opposite ends of the scraper 5 are provided with notches, and magnets 4 are fixedly embedded in the notches. Boxes 14 are fixedly connected to opposite sides of the outer wall of the box 3. The two boxes 14 and the two magnets 4 are respectively located on the same vertical plane. The two boxes 14 and the cylindrical section at the bottom of the threaded rod 17 are at the same horizontal height. A permanent magnet 16 that slides vertically is provided inside the box 14. The permanent magnet 16 and the magnet 4 attract each other. A rubber spring 15 is fixedly connected to the lower surface of the permanent magnet 16. The bottom end of the spring 15 is fixedly connected to the inner bottom of the box 14.
[0022] The drying mechanism includes a warm air blower and a liquid tank 7. The warm air blower is installed outside the housing 3. An air guide pipe 10 is connected to the air outlet of the warm air blower. The air outlet end of the air guide pipe 10 passes through the housing 3 and is located on the same vertical plane as the inner wall of the housing 3. The air outlet end of the air guide pipe 10 is located above the grinding rod 11. The liquid tank 7 is fixedly connected to the housing 3. A liquid pipe 8 is connected to the bottom of the liquid tank 7. The end of the liquid pipe 8 away from the liquid tank 7 passes through the housing 3 and is located on the same vertical plane as the inner wall of the housing 3. An atomizing nozzle 9 is provided at this end of the liquid pipe 8. An air pipe is connected to the top of the liquid tank 7. A pressure pump is connected to the end of the air pipe away from the liquid tank 7.
[0023] The specific implementation process is as follows:
[0024] Before use, the scraper 5 is located at the top inside the box 3. When using, pour the prickly pear extract that needs to be dried and ground into the liquid tank 7, and then turn on the heater. When the heater is running, hot air is injected into the box 3 through the air pipe 10 to heat the inside of the box 3. At this time, the pressure pump is turned on. 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. Under the pressure, the prickly pear extract in the liquid tank 7 is forced into the liquid pipe 8, and then sprayed into the box 3 in an atomized form through the atomizing nozzle 9. The prickly pear extract that enters the box 3 is heated, causing the water it contains to evaporate quickly into water vapor, which is then separated from the prickly pear extract. At this time, the water vapor flows upward inside the box 3, passes through the air hole 6 and the exhaust hole 2 and flows out of the box 3. The dried prickly pear extract becomes prickly pear extract. Under the action of gravity, the prickly pear extract falls onto the toothed disc 13 at the bottom of the box 3 or adheres to the inner wall of the box 3. After drying for a period of time, the motor 1 is started. When the motor 1 is running, it drives the threaded rod 17 to rotate through the output shaft. When the threaded rod 17 rotates, it drives the grinding rod 11 to rotate on the toothed disc 13. When the grinding rod 11 rotates, it grinds the prickly pear extract that has fallen onto the toothed disc 13 into powder. Simultaneously, as the threaded rod 17 rotates, it pushes the scraper 5 downwards. Since the edge of the scraper 5 slides against the inner wall of the housing 3, the scraper 5 scrapes off the prickly pear extract adhering to the inner wall of the housing 3 and the surface of the threaded rod 17 as it moves downwards, causing it to fall onto the gear disc 13 for grinding. When the scraper 5 reaches the bottom of the threaded rod 17, its lower surface contacts the upper surface of the grinding rod 11. Therefore, as the grinding rod 11 rotates, it scrapes off the prickly pear extract adhering to the lower surface of the scraper 5. Since the bottom of the threaded rod 17 is cylindrical, the threaded rod 17 can no longer push the scraper 5 to move further after it reaches the cylindrical section. After the lower surface of the scraper 5 is cleaned, the motor 1 is started in reverse. The output shaft of the motor 1 rotates in reverse, causing the threaded rod 17 to rotate in reverse. This reverse rotation of the threaded rod 17 causes the scraper 5 to move upwards until it reaches the top of the housing 3.
[0025] When the scraper 5 moves down to the bottom of the threaded rod 17, the magnet 4 and the permanent magnet 16 attract each other. As the threaded rod 17 rotates, causing the scraper 5 to continue moving down, the magnet 4 drives the permanent magnet 16 to move downward within the housing 14 through attraction. 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 pushes the scraper 5 downward. Under the elastic force of the spring 15, the permanent magnet 16 is pushed upward within the housing 14. When the permanent magnet 16 moves upward, it drives the scraper 5 to move upward through the magnet 4 and contact the bottom 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 better complete the engagement, thus allowing the scraper 5 to move upward smoothly on the threaded rod 17.
