Description

Technical Field

[0001] This utility model relates to the field of Polygonatum production technology, and in particular to a high-efficiency pulverizer for Polygonatum production. Background Technology

[0002] Polygonatum is the dried rhizome of Polygonatum sibiricum, Polygonatum multiflorum, or Polygonatum yunnanensis, all belonging to the Liliaceae family. It is often regarded as a "nourishing" food or medicine. In the processing of Polygonatum sibiricum, the pulverizing process is crucial. Pulverized Polygonatum sibiricum can be made into powders of different particle sizes according to needs, making it convenient to mix into food (such as meal replacement powder) and medicine (such as capsules).

[0003] When pulverizing Polygonatum, it is generally fed into a pulverizer and pulverized by rotating pulverizing rollers. For example, a Polygonatum pulverizing processing equipment disclosed in patent number CN219187076U uses a drive motor to operate, and the pulverizing rollers rotate accordingly. Since the two pulverizing rollers are meshed and connected, after the raw material falls into the feed hopper, it can be initially pulverized by the mutual squeezing of the two pulverizing rollers, making the Polygonatum pulverized more uniformly. However, this solution lacks a cooling mechanism. Polygonatum contains a lot of sugars and mucilage, which can easily generate heat due to mechanical friction during pulverization, causing the material to soften and stick to the equipment, thereby affecting the pulverization efficiency and the quality of the finished product. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency pulverizer for the production of Polygonatum sibiricum, in order to solve the problem of low pulverization efficiency of existing pulverizers.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency pulverizer for the production of Polygonatum sibiricum, including a frame; A crushing box is provided at one end of the top of the frame, and a feed inlet is provided at the top of the crushing box. Cooling mechanisms are provided on both sides of the crushing box, and each cooling mechanism includes a cooling box. Cooling pipes are provided inside the cooling boxes, and a contact plate is provided on the side of the cooling box near the crushing box. Heat-conducting blocks are evenly distributed on the contact plate. A heat pump is provided on the frame on one side of the crushing box. The water outlet of each cooling pipe is connected to the heat pump through a water outlet pipe, and a water pump is provided on each water outlet pipe. A conveyor belt is installed above the feed inlet, and an arched frame is installed on the top of the conveyor belt. Drying chambers are installed on both sides inside the arched frame, and air outlets are evenly distributed on one side of the drying chambers. The output end of the heat pump is connected to the drying chambers through hot air ducts.

[0006] Preferably, a first crushing roller and a second crushing roller are respectively provided at both ends inside the crushing box, and a first drive motor is fixed at one end of one side of the crushing box. The output end of the first drive motor is connected to the first crushing roller, and crushing teeth are evenly provided at both ends inside the crushing box.

[0007] Preferably, one end of both the first and second crushing rollers extends outside the crushing chamber, and one end of the first and second crushing rollers is respectively provided with a driving gear and a driven gear.

[0008] The above structure enables efficient extrusion and shearing of Polygonatum odoratum, improving the uniformity and speed of its pulverization.

[0009] Preferably, the top of the inside of the arched frame is provided with a bidirectional lead screw, and each end of the bidirectional lead screw is fitted with a movable sleeve, and the bottom end of each movable sleeve is provided with a loosening rake through a cylinder.

[0010] With the above structure, the cylinder can adjust the height of the loosening rake, and the two-way screw and movable sleeve can drive the loosening rake to move laterally, thereby uniformly loosening the Polygonatum piled on the conveyor belt and preventing Polygonatum from clumping and affecting the subsequent drying and pulverizing effect.

[0011] Preferably, a second drive motor is fixed to one end of the top of the arched frame, and the output end of the second drive motor is connected to a bidirectional lead screw.

[0012] With the above structure, the second drive motor can precisely drive the bidirectional lead screw to rotate, providing stable power for the movement of the movable sleeve and the loosening rake.

[0013] Preferably, one end of the heat-conducting block contacts the outer wall of the crushing chamber, and the other end of the heat-conducting block extends into the interior of the cooling chamber. The heat-conducting blocks are all made of copper alloy.

[0014] Through the above structure, the heat-conducting block made of copper alloy can quickly transfer the heat from the outer wall of the crushing chamber to the cooling chamber, achieving efficient heat dissipation of the crushing chamber and preventing high temperature inside the chamber from damaging the active ingredients of Polygonatum odoratum.

[0015] Preferably, the drying oven is equipped with a filter screen, and the filter screen is made of activated carbon.

[0016] Through the above structure, the activated carbon filter can filter impurities and odors carried by the hot air in the drying oven, ensuring that the dried Polygonatum is not contaminated and improving the cleanliness and quality of the finished Polygonatum product.

[0017] The advantages of the high-efficiency pulverizer for producing Polygonatum sibiricum provided by this utility model are as follows: The system is equipped with a frame, a crushing box, a first crushing roller, a second crushing roller, a first drive motor, a drive gear, a driven gear, a feed inlet, and a cooling mechanism. The cooling mechanism includes a cooling box, cooling pipes, a contact plate, a heat-conducting block, and a water outlet pipe. After the Polygonatum is introduced into the crushing box, the first drive motor drives the first crushing roller to rotate. When the first crushing roller rotates, the meshing motion of the drive gear and the driven gear causes the second crushing roller to rotate relative to the first crushing roller, thus crushing the Polygonatum. During the crushing process, the heat in the crushing box is evenly transferred to the cooling box through the heat-conducting block. At the same time, cooling water flows into the cooling pipe and exchanges heat with the heat as it flows in the cooling pipe, effectively maintaining a suitable temperature in the crushing box. This prevents high temperatures from damaging some of the active ingredients in the Polygonatum, affecting its efficacy or nutritional value. It also keeps the material brittle, preventing it from softening and sticking inside the equipment, thus improving the crushing efficiency. Furthermore, by incorporating a conveyor belt, frame, drying chamber, air outlet, heat pump, and hot air duct, the water in the cooling pipe absorbs heat and then enters the heat pump through the water outlet. The heat pump extracts heat from the low-temperature hot water, consumes a small amount of electricity to raise the temperature of this heat, and finally releases it to the air to create high-temperature hot air. The hot air enters the drying chamber through the hot air duct and is discharged through the air outlet to dry the Polygonatum transported on the conveyor belt. This process dries the Polygonatum, reduces its moisture content, and makes it more brittle and hard, allowing it to be easily crushed without the powder sticking together. At the same time, by directly recovering the waste heat generated during the crushing of Polygonatum, only a small amount of electricity is needed to convert it into high-temperature hot air for drying, significantly reducing additional heating energy consumption and lowering the overall production cost.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 The present invention provides a high-efficiency pulverizer for the production of Polygonatum sibiricum, including a frame 1; Please see Figure 1-2 The machine frame 1 has a crushing box 2 at one end of its top, and a feed inlet 3 at the top of the crushing box 2. A conveyor belt 4 is mounted above the feed inlet 3. A first crushing roller 9 and a second crushing roller 10 are respectively installed at both ends inside the crushing box 2. A first drive motor 8 is fixed at one end of one side of the crushing box 2. The output end of the first drive motor 8 is connected to the first crushing roller 9. Crushing teeth 11 are evenly arranged at both ends inside the crushing box 2. One end of the first crushing roller 9 and the second crushing roller 10 extends to the outside of the crushing box 2. A drive gear 12 and a driven gear 13 are respectively installed at one end of the first crushing roller 9 and the second crushing roller 10. The Solomon's seal that needs to be crushed is placed on the conveyor belt 4, which transports the Solomon's seal towards the crushing box 2. The Solomon's seal enters the crushing box 2 through the feed inlet 3. The first drive motor 8 starts to run, and its output end is connected to the first crushing roller 9, driving the first crushing roller 9 to rotate at high speed. One end of the first crushing roller 9 extends to the outside of the crushing box 2. The drive gear 12 set at this end also rotates. Since the drive gear 12 meshes with the driven gear 13, and the driven gear 13 is installed at one end of the second crushing roller 10, the rotation of the drive gear 12 will cause the driven gear 13 to drive the second crushing roller 10 to rotate relative to the first crushing roller 9. During the relative rotation of the first crushing roller 9 and the second crushing roller 10, the Solomon's seal is torn and crushed by the squeezing force and friction between them. At the same time, the crushing teeth 11, which are evenly arranged at both ends inside the crushing box 2, also play a role. Under the collision and friction with the crushing teeth 11, the Solomon's seal is further crushed into smaller particles, completing the main crushing operation. Please see Figure 1-3 Cooling mechanisms 6 are provided on both sides of the crushing box 2. The cooling mechanism 6 includes a cooling box 601. Cooling pipes 602 are provided inside the cooling box 601. A contact plate 603 is provided on the side of the cooling box 601 near the crushing box 2. Heat-conducting blocks 604 are evenly distributed on the contact plate 603. One end of the heat-conducting block 604 contacts the outer wall of the crushing box 2, and the other end of the heat-conducting block 604 extends into the interior of the cooling box 601. The heat-conducting blocks 604 are all made of copper alloy. A heat pump 22 is provided on the frame 1 on one side of the crushing box 2. The water outlet of the cooling pipe 602 is connected to the heat pump 22 through a water outlet pipe 605. A water pump 7 is provided on the water outlet pipe 605. When the first grinding roller 9 and the second grinding roller 10 are grinding Polygonatum at high speed, the grinding box 2 will generate a lot of heat. At this time, one end of the heat-conducting block 604 evenly distributed on the contact plate 603 is in close contact with the outer wall of the grinding box 2, and the other end extends into the interior of the cooling box 601. The heat-conducting block 604 is made of copper alloy and has good thermal conductivity. It can quickly transfer the heat in the grinding box 2 to the cooling box 601. At the same time, the water pump 7 located on the water outlet pipe 605 is started, which causes the water in the cooling pipe 602 to flow continuously. The flowing water exchanges heat with the heat transferred through the heat-conducting block 604 in the cooling pipe 602 and carries away the heat, thereby maintaining a suitable temperature in the grinding box 2. This can prevent high temperature from destroying some of the active ingredients in Polygonatum and affecting its efficacy or nutritional value. It can also keep the material brittle and prevent it from softening and sticking to the inside of the equipment, ensuring the efficient operation of the grinding work. Please see Figure 4-5 An arched frame 5 is provided on the top of the conveyor belt 4. Drying boxes 14 are provided on both sides inside the arched frame 5, and air outlets 15 are evenly distributed on one side of the drying box 14. The output end of the heat pump 22 is connected to the drying box 14 through the hot air duct 23. The water in cooling pipe 602 absorbs heat generated by pulverizing chamber 2 during heat exchange, becoming low-temperature hot water. This low-temperature hot water enters heat pump 22 through outlet pipe 605. (Heat pump 22 includes an evaporator, compressor, and condenser. Its working principle is based on the cyclical change of refrigerant state. In the evaporator, the refrigerant absorbs heat from the low-temperature hot water and evaporates, becoming a low-temperature, low-pressure gaseous state. Then it is drawn into and compressed by the compressor, and the pressure and temperature rise sharply, becoming a high-temperature, high-pressure gaseous state. Then the high-temperature, high-pressure gaseous refrigerant enters the condenser, where it exchanges heat with the outside air, releasing the absorbed heat and the heat generated during compression to the air, creating high-temperature hot air. Heat pump 22 is existing equipment.) High-temperature hot air enters the drying chamber 14 through the hot air duct 23 and is blown out from the air outlets 15 evenly distributed on one side of the drying chamber 14 to dry the Polygonatum on the conveyor belt 4. The drying chamber 14 is equipped with a filter screen 21, which is made of activated carbon to filter the hot air. In this process, not only can the Polygonatum be dried and easily crushed, but the waste heat generated during the crushing of Polygonatum is also recovered and utilized, converting the heat that might otherwise be wasted into the energy required to dry the Polygonatum, reducing the energy consumption required for additional heating. The top of the arched frame 5 is provided with a two-way lead screw 16, and the two ends of the two-way lead screw 16 are respectively fitted with movable sleeves 17. The bottom of each movable sleeve 17 is provided with a loosening rake 20 through a cylinder 19. One end of the top of the arched frame 5 is fixed with a second drive motor 18, and the output end of the second drive motor 18 is connected to the two-way lead screw 16. During the process of transporting Polygonatum sibiricum on conveyor belt 4, the second drive motor 18 is turned on, and its output end drives the bidirectional lead screw 16 to rotate. The movable sleeve 17 fitted on the bidirectional lead screw 16 will move towards or away from it due to the rotation of the bidirectional lead screw 16. The bottom end of the movable sleeve 17 is connected to the loosening rake 20 through the cylinder 19. The loosening rake 20 moves with the movement of the movable sleeve 17 to loosen the Polygonatum sibiricum on the conveyor belt 4, so as to prevent the Polygonatum sibiricum from accumulating and clumping, and to ensure the uniformity of subsequent drying and crushing.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
