Description

Technical Field

[0001] The invention relates to the technical field of medicinal material processing equipment, in particular to equipment and a method for freeze-drying ganoderma lucidum germ slurry. Background Art

[0002] As people pay more and more attention to health, Lingzhi, as a traditional Chinese medicine with extremely high medicinal value and health-care effects, has received extensive attention. Lingzhi germ, as an important part of the early growth of Lingzhi, contains rich nutrients such as polysaccharides, triterpenoids, proteins, etc., and has multiple effects such as anti-oxidation, enhancing immunity, regulating blood sugar and blood lipids, etc.

[0003] In the traditional processing of Ganoderma lucidum, natural drying and hot air drying are often used to treat Ganoderma lucidum germs. However, these methods have many disadvantages. Natural drying is greatly affected by weather conditions, takes a long time to dry, is easily contaminated by dust, insects, etc., and nutrients are easily lost during the drying process. Although hot air drying can speed up the drying speed, due to the high temperature, it is easy to destroy the heat-sensitive nutrients in the Ganoderma lucidum germs, reducing the nutritional value of the product.

[0004] In addition, existing drying equipment often has the problem of uneven drying when processing Ganoderma lucidum germ slurry. Some areas are over-dried while other areas are under-dried, resulting in unstable product quality. At the same time, the operation of the equipment is complicated and requires professional technicians to operate and maintain it, which increases labor costs. Summary of the invention

[0028] (III) Beneficial effects

[0029] Compared with the prior art, the present invention provides a device and method for freeze-drying ganoderma lucidum germ slurry, which has the following beneficial effects:

[0030] 1. The mobile mechanism is used to assist manual movement of the placement rack out of or into the freeze-drying box, which can reduce manual workload and energy consumption. Universal wheels are set under the equipment box, so that the device can be easily moved to different positions, improving the flexibility and operability of the equipment to meet the needs of different work scenes. The door of the freeze-drying box is cleverly designed and connected to the support through a torsion spring. It is convenient to place and take out the placement rack, without complicated operating procedures, and improves work efficiency.

[0031] 2. The placement rack is adsorbed by the adsorption mechanism during the process of moving the placement rack in. Since there is no force-bearing surface between the moving seat and the placement rack at this time, the placement rack is moved only by the friction between the lower surface of the placement rack and the upper surface of the moving seat. The auxiliary force required by the operator is relatively large. The adsorption operation can ensure the stability of the placement rack during the moving process, thereby reducing the need for auxiliary force.

[0032] 3. An upward airflow is applied to the placement rack during the removal process through the adsorption mechanism. At this time, the placement rack is pushed by the end surface of the moving seat and the end surface of the placement rack. The upward force of the airflow is opposite to the gravity of the placement rack, thereby reducing the auxiliary force of the operator.

[0033] 4. The principle that the liquid level in the communicating vessel is level and that the electrorheological fluid can be converted between solid and liquid states is utilized to realize the correlation between the movement of the push rod and the balance frame in the vertical direction, thereby ensuring that the placement rack is in a horizontal state when it is completely entered into the freeze-drying chamber, and avoiding friction between the balance frame and the placement rack when the placement rack is moved out of the freeze-drying chamber, thereby avoiding damage to the lower end surface of the placement rack.

[0034] In summary, the present invention meets the demand for quick freezing of Ganoderma lucidum germ slurry, improves the flexibility and operability of the equipment, meets the needs of different working scenarios, and can ensure the stability of the placement rack during the moving process through the adsorption operation, thereby reducing the demand for auxiliary force.

When the refrigeration mechanism is refrigerating, the condenser 6, the evaporator 23, the expansion valve 3 and the compressor 22 work together to discharge the hot air inside the equipment box 1 and reduce the temperature inside the equipment box 1, and then the exhaust fan 17 and the return fan 18 are used to reduce the temperature inside the freeze-drying box 2, so as to realize the quick freezing of the placement rack 11 inside the freeze-drying box 2 and the materials inside the placement rack 11;

[0050] A moving mechanism is installed in the device box 1, and the moving mechanism includes a motor 29, and the motor 29 is installed on the inner wall of the device box 1, and a worm 33 is installed on the output shaft of the motor 29. A mounting shaft 28 is installed on the inner wall of the device box 1 through a bearing, and a worm wheel 32 and a first gear 31 are installed on the mounting shaft 28, and the worm wheel 32 is meshed with the worm 33. A moving groove 15 and a meshing through hole 20 are opened on the inner bottom wall of the placement cavity 10, and the moving groove 15 is connected to the meshing through hole 20. A threaded rod 16 is horizontally installed in the moving groove 15, and a second gear 21 is installed on the threaded rod 16, and the second gear 21 is meshed with the first gear 31. 1 is meshed, and the second gear 21 and the first gear 31 are partially located in the meshing through hole 20, the threaded rod 16 is threadedly connected with the moving seat 12, and the placement rack 11 is located on the moving seat 12. When the moving mechanism is working, the motor 29 is turned on, the motor 29 waits for the worm 33 to rotate, and the worm 33 drives the worm wheel 32 to rotate through meshing, so the installation shaft 28 rotates accordingly and drives the first gear 31 to rotate, and the second gear 21 rotates with the first gear 31 while driving the threaded rod 16 to rotate, and the threaded rod 16 rotates to drive the moving seat 12 to move in the freeze-drying box 2, and then drives the placement rack 11 to move in the freeze-drying box 2;

[0051] The moving seat 12 includes a placing seat and a moving block, and the moving block is located in the moving groove 15, the placing seat is located on the moving block, and the placing frame 11 is located on the placing seat;

[0052] An adsorption mechanism is installed between the output end of the motor 29 and the movable seat 12, and the adsorption mechanism includes a blower body 26, and the blower body 26 is installed on the inner bottom wall of the equipment box 1, the output shaft of the motor 29 extends into the blower body 26 and is installed with an impeller, the air outlet end of the blower body 26 is installed with an air outlet pipe 7, and the air outlet pipe 7 penetrates the equipment box 1 and extends outward, the air inlet end of the blower body 26 is installed with a connecting hose 14, and a one-way valve 27 is installed on the connecting hose 14, a buffer cavity 34 is provided inside the movable seat 12, and one end of the connecting hose 14 away from the blower body 26 is connected to the buffer cavity 34, and the specific connection method is that a short tube is fixedly connected to the movable seat 12, and one end of the short tube extends into the buffer cavity 34, and the other end of the short tube is connected to the connecting hose 14 through a connecting flange, and a plurality of adsorption holes 13 are evenly provided on the upper surface of the movable seat 12, and each adsorption hole 13 is connected to the buffer cavity 3 4 is connected, when the motor 29 in the moving mechanism is performing a forward rotation operation (i.e., driving the placement rack 11 to move inside the freeze-drying box 2), the impeller also rotates forwardly with the output shaft of the motor 29, and the blower body 26 draws the airflow out of the freeze-drying box 2 through the adsorption holes 13, the buffer chamber 34 and the connecting hose 14. At this time, multiple adsorption holes 13 simultaneously adsorb the placement rack 11, and adsorb the placement rack 11 on the moving seat 12 to ensure the stability of the placement rack 11 during the movement process. When the motor 29 in the moving mechanism is performing a reverse rotation operation (i.e., driving the placement rack 11 to move outside the freeze-drying box 2), the airflow flows from the outside of the device to the inside of the freeze-drying box 2, and the airflow moves toward the bottom of the placement rack 11 through the adsorption holes 13. At this time, the placement rack 11 is pushed by the end surface of the moving seat 12 and the end surface of the placement rack 11, and the upward force of the airflow can also reduce the auxiliary force of the operator;

[0053] A limiting groove is provided at one end of the freeze-drying box body 2 away from the door body 4, and a portion of the movable seat 12 is located in the limiting groove;

[0054] A balancing mechanism is installed on the inner bottom wall of the device box 1, and the balancing mechanism includes a communicating vessel 30, and the communicating vessel 30 is fixedly connected to the inner bottom wall of the device box 1, and the communicating vessel 30 is made of conductive material. A first piston 36 and a second piston 37 are slidably connected in the communicating vessel 30. Figure 2In the state shown, the lower surface of the first piston 36 is lower than the lower surface of the second piston 37, the communicating vessel 30 is filled with an electrorheological fluid 38, and the electrorheological fluid 38 is filled between the first piston 36 and the second piston 37, a power supply 24 is installed on the inner bottom wall of the equipment box 1, and the power supply 24 is connected to the communicating vessel 30 through a wire, a piston rod is installed on the upper end of the first piston 36, and a push rod 35 is fixedly connected to the upper end of the piston rod, and an arc surface transition is adopted between the side wall of the push rod 35 close to the placement rack 11 and the upper surface of the push rod 35, a square hole 5 is opened on the lower surface of the freeze-drying box 2, and the square hole 5 is connected to the limit groove, and a sealing member (not shown in the figure) is fixedly connected to the inner side wall of the square hole 5, and the push rod 35 passes through the sealing member and abuts against the lower surface of the movable seat 12, and a balancing frame 25 is fixedly connected to the second piston 37, and the push rod 35 and the balancing frame 25 are made of the same material, and the upper end of the balancing frame 25 passes through the freeze-drying box 2 and abuts against the lower surface of the placement rack 11;

[0055] When the moving seat 12 moves to the pushing rod 35, the edge of the moving seat 12 contacts the arc surface of the pushing rod 35, and the moving seat 12 continues to move through the arc surface to push the pushing rod 35 downward until the upper end surface of the pushing rod 35 abuts against the lower end surface of the moving seat 12. In this process, the pushing rod 35 pushes the first piston 36 downward through the piston rod. During the downward movement of the first piston 36, the electrorheological fluid 38 pushes the second piston 37 to move upward. The second piston 37 simultaneously drives the balancing frame 25 to move upward. When the upper end surface of the pushing rod 35 abuts against the lower end surface of the moving seat 12, the upper end of the balancing frame 25 abuts against the lower end surface of the placing rack 11. At this time, the lower surface of the placing rack 11 is parallel to the lower surface of the freeze-drying box 2. Then, the power source 24 is turned on, and the electrorheological fluid 38 is energized through the power source 24. Due to the special physical properties of the electrorheological fluid 38, it changes from liquid to solid after being energized. At this time, the positions of the first piston 36 and the second piston 37 can be guaranteed to remain unchanged, thereby ensuring the balance of the placement rack 11. Before the placement rack 11 is moved out, the power source 24 is turned on again, and the electrorheological fluid 38 changes from solid to liquid. When the moving seat 12 is moved out from the upper end of the push rod 35, due to the principle that the liquid levels at both ends of the communicating vessel are level, the balance rack 25 pushes the second piston 37 downward under the action of its own gravity until the lower surface of the first piston 36 and the lower surface of the second piston 37 are in the same plane. At this time, the upper end surface of the balance rack 25 is not higher than the inner bottom wall of the placement chamber 10;

[0056] The balance frame 25 includes a piston column 2501, and the piston column 2501 is connected to the second piston 37.

The upper end of each push column 2502 is set with an arc surface. The push column 2502 is connected to the freeze-drying box 2 through a sliding sealing ring 19. The sliding sealing ring 19 and the sealing member are made of the same material. The friction coefficient μ between the push rod 35 and the sealing member is 1 , the friction coefficient μ between the sliding seal ring 19 and the balance frame 25 2 Equal, the sum of the weight of the push rod 35 and the piston rod G 1 Weight of the gimbal 25G 2 If the friction force on the push rod 35 during the movement is equal to Ff 1 =μ 1 G 1 The friction force on the balance frame 25 during movement is Ff 2 =μ 2 G 2 , then Ff 1 =Ff 2 , which can ensure that when the moving seat 12 pushes the push rod 35 to descend, the height to which the first piston 36 descends is equal to the height to which the second piston 37 rises. At the same time, it can ensure that when the moving seat 12 separates from the push rod 35, the height to which the push rod 35 rises under the action of gravity is equal to the height to which the balance frame 25 descends.

[0057] A method for freeze-drying ganoderma lucidum germ slurry comprises the following steps:

[0058] S1. Preservation of fresh Ganoderma lucidum sprouts: In order to ensure the freshness of Ganoderma lucidum sprouts, the following methods can be used for preservation:

[0059] First of all, try to shorten the time from picking the Ganoderma lucidum buds to entering the preparation process to reduce their exposure time to the external environment and maintain their freshness to the greatest extent; use moist gauze or paper towels to gently wrap the Ganoderma lucidum buds to maintain the humidity of the surrounding environment, or place the Ganoderma lucidum buds in a container with certain humidity and temperature control, and ensure that the humidity is between 60%-80% to prevent the Ganoderma lucidum buds from losing moisture due to drying and affecting their freshness. Place them in an environment with a temperature of 0-5℃. Low temperature can reduce the metabolic rate of the Ganoderma lucidum buds and delay their aging and deterioration process; during storage and transportation, be careful to handle the Ganoderma lucidum buds to avoid squeezing them. Soft packaging materials, such as foam pads or sponges, can be used to place the Ganoderma lucidum buds individually or in layers to prevent the Ganoderma lucidum buds from being damaged by pressure.

[0060] S2. Cleaning: Use running water to carefully scrub the dust and other debris on the surface of the Ganoderma lucidum germ by hand to ensure the cleanliness of the raw materials.

[0061] S3, slicing; using a slicer, the cleaned Ganoderma lucidum germ is carefully chopped into a paste state for subsequent operations;

[0062] S4, pulping: put the germ crushed material into the vibrating rod abrasive barrel, add appropriate amount of clean water and stir well, install the barrel on the machine and work for 10 minutes to mix and grind the pulp. During this period, turn the barrel over every 3 minutes to ensure the uniformity and fineness of the pulp.

[0063] S5. Refrigerated storage: put the prepared Ganoderma lucidum germ slurry into a barrel and transfer it to a cold storage to wait for freeze-drying treatment.

[0064] S6, quick freezing and drying; the Ganoderma lucidum germ slurry is evenly spread on the rack 11, and then transferred to the freeze-drying chamber 2, set the temperature to -35 ° C, and perform quick freezing for 3 hours; after the quick freezing is completed, the rack 11 is directly transferred to the vacuum drying chamber 39 (such as Figure 2 As shown), start vacuuming. When the vacuum degree reaches 36-48 Pa, set the water temperature of the drying chamber to 45°C and start heating. Continue drying until the vacuum degree is 5-7 Pa, then end the drying and open the chamber door to discharge the material.

[0065] S7, crushing and bagging again; the freeze-dried slurry is re-loaded into the vibrating rod grinding barrel and crushed again for 10 minutes. During this period, the barrel is still turned over every 3 minutes. Finally, the material is discharged and bagged to obtain high-quality Ganoderma lucidum germ freeze-dried powder.

[0066] Process optimization of improving the antioxidant capacity of wheat germ through solid-state fermentation of Ganoderma lucidum:

[0067] In the preparation process of Ganoderma lucidum germ freeze-dried powder, a step of solid-state fermentation of Ganoderma lucidum with wheat germ can be introduced. First, high-quality wheat germ is prepared, and Ganoderma lucidum strains are inoculated on the wheat germ for solid-state fermentation. By optimizing the fermentation conditions, such as temperature, humidity, fermentation time, etc., Ganoderma lucidum can fully grow and reproduce on the wheat germ to produce more active ingredients. The fermented wheat germ has a stronger antioxidant capacity. Mixing it with Ganoderma lucidum germ for subsequent preparation steps can further enhance the nutritional value and efficacy of Ganoderma lucidum germ freeze-dried powder.

[0068] During the quick freezing and drying process, the door body 4 is first pulled outward, the torsion spring is charged, and the placement rack 11 containing the Ganoderma lucidum germ slurry is placed in the placement cavity 10 of the freeze-drying box 2. After ensuring that the placement rack 11 is completely inserted into the freeze-drying box 2, the torsion spring automatically drives the door body 4 to rotate, so that the door body 4 is stuck in the door groove 9 to ensure the airtightness of the freeze-drying box 2; then the refrigeration mechanism is started, and the condenser 6, evaporator 23, expansion valve 3 and compressor 22 work together to discharge the hot air inside the equipment box 1 and reduce the equipment The temperature inside the box 1 is reduced by the exhaust fan 17 and the return fan 18 to lower the temperature inside the freeze-drying box 2, and the placement rack 11 and the Ganoderma lucidum germ slurry inside are quickly frozen; after the freeze-drying process is completed, when the placement rack 11 needs to be taken out, the power supply 24 is turned on again to change the electrorheological fluid 38 from solid to liquid, the moving mechanism is started, and the motor 29 rotates in the opposite direction to drive the placement rack 11 to move to the outside of the freeze-drying box 2, and the end of the placement rack 11 directly pushes the door 4 open until the placement rack 11 is completely moved out of the freeze-drying box 2.
