Description

Technical Field

[0001] This utility model relates to the field of matsutake mushroom processing technology, and in particular to a pulverizing device for freeze-dried matsutake mushrooms. Background Technology

[0002] Matsutake polysaccharides are natural active ingredients extracted from matsutake mushrooms. They possess various biological activities, such as enhancing immunity and anti-tumor activity, thus showing broad application prospects in health products, pharmaceuticals, and functional foods. Currently, raw material processing is a crucial step in the extraction of matsutake polysaccharides. Freeze-dried matsutake mushrooms, as a high-quality raw material for matsutake polysaccharide extraction, have advantages such as good preservation and minimal loss of active ingredients. However, the relatively hard texture of freeze-dried matsutake makes direct polysaccharide extraction inefficient. Therefore, it is necessary to break them into smaller particles using a pulverizing device to improve the extraction efficiency and purity of the polysaccharides.

[0003] A search revealed Chinese patent application CN201922498421.2, which discloses a matsutake mushroom grinding device. The device includes a frame with feed hoppers at both ends. A crushing box is located at the outlet of each feed hopper, containing crushing blades. A discharge pipe is located at the bottom of the crushing box, with a baffle between the discharge pipe and the crushing box. A moving grinding disc is located at the outlet of the discharge pipe, with a feed inlet below the outlet of the discharge pipe. A stationary grinding disc is mounted on the moving grinding disc, and a discharge channel is located on one side of the stationary grinding disc. A receiving box is located at the outlet of the discharge channel. The matsutake mushroom grinding device in the aforementioned patent has the following drawback: high-speed rotation during crushing causes friction and heating of the blades, which can damage nutrients in the matsutake mushroom, such as polysaccharides, affecting the subsequent polysaccharide extraction.

[0012] As a further embodiment of this utility model: the fragmentation structure includes a base plate fixedly connected to the inner wall of one side of the machine body, a top support mechanism fixedly connected to the top surface of the base plate, and a spike plate fixedly connected to the extension end of the top support mechanism.

[0013] An inclined plate is fixedly connected to the top surface of the bottom plate located below the discharge end of the precooling box, and the bottom surface of the spiked plate is in contact with the top surface of the inclined plate.

[0014] The inner wall of the base plate is provided with a discharge port;

[0015] A hopper is fixedly connected to the bottom outer wall of the base plate.

[0016] As a further embodiment of this utility model: the preliminary crushing implementation structure includes two crushing rollers rotatably connected to the inner wall of one side of the machine body, two gears rotatably connected to the outer wall of one side of the machine body, and a driving component, wherein the outer walls of the two gears mesh with each other, and one end of the two gears is connected to one end of the two crushing rollers respectively through a coupling.

[0017] As a further embodiment of this utility model: the driving component includes a support plate fixedly connected to one side of the machine body, a motor fixedly connected to the top surface of the support plate, a bevel gear assembly with one end connected to the output end of the motor via a coupling, and a transmission belt.

[0018] The bevel gear assembly includes a main gear and a secondary gear that mesh on their outer walls. The top end of the secondary gear is rotatably connected to the bottom surface of the machine body, and one end of the main gear is rotatably connected to one side of the machine body.

[0024] Compared with the prior art, this utility model provides a pulverizing device for freeze-dried matsutake mushrooms, which has the following beneficial effects:

[0025] 1. The freeze-dried matsutake mushroom pulverizing device is equipped with a material pre-processing component. The freeze-dried matsutake mushroom rolls down along the guide plate until it covers the upper surface of each layer of the guide plate. This passively cools the mushroom during contact with the guide plate, allowing for low-temperature pulverization later. This preserves the active ingredients of the matsutake mushroom during pulverization and avoids affecting the extraction of matsutake polysaccharides due to frictional heat generated during pulverization.

[0026] 2. The pulverizing device for freeze-dried matsutake mushrooms controls the start of the top support mechanism, and then uses the spiked plate to reciprocate and compress the freeze-dried matsutake mushrooms output from the pre-cooling box discharge end. Since the matsutake mushrooms are freeze-dried and contain little moisture, they can be hammered and broken into several small pieces of different sizes when they come into contact with the spiked plate, thus quickly completing the first pulverizing work of the matsutake mushrooms.

[0027] 3. The freeze-dried matsutake mushroom crushing device starts with a motor, which drives a bevel gear assembly to rotate. This assembly, via a transmission belt, drives two gears, causing the two crushing rollers to rotate in opposite directions. This crushes the matsutake mushroom pieces exiting the hopper. Simultaneously, a high-speed transmission belt drives a crushing roller to further crush the material entering the crushing chamber after it has been crushed by the crushing rollers, effectively saving mechanical energy.

[0034] Example 1

[0035] A pulverizing device for freeze-dried matsutake mushrooms, such as Figure 1-2 As shown, it includes a machine body 1 and an auger screw conveyor 6 located on one side of the machine body 1. The circumferential outer wall of the auger screw conveyor 6 is fixed with a feed port 7 by bolts. The auger screw conveyor 6 includes a drive motor, a screw conveyor, etc. The prior art is used here and will not be described in detail.

[0036] Furthermore, the top surface of the machine body 1 is provided with a material prefabrication assembly, which includes a precooling box 2 fixed to the outer wall of the top of the machine body 1 by bolts, a guide plate 3 fixed to the inner wall of one side of the precooling box 2 by bolts and having a hollow interior, and a three-way pipe 17 fixed to one side of the precooling box 2 by bolts. Two ends of the three-way pipe 17 are respectively connected to the inlet and outlet ends of the guide plate 3 by bolts.

[0037] Preferably, the guide plate 3 is M-shaped, such as... Figure 1-2 As shown, each layer of the guide plate 3 has an inclined transverse surface so that the matsutake mushrooms on it can slide smoothly.

[0038] In a further preferred embodiment, each layer of the guide plate 3 has an opening 13 on the transverse side near the precooling box 2; cold water is injected into the guide plate 3 using a three-way pipe 17.

[0039] In a further preferred embodiment, the inner walls of the precooling box 2 are all filled with a heat insulation layer 201; this effectively isolates the temperature exchange between the inside and outside of the precooling box 2 and maintains the internal temperature of the precooling box 2 as much as possible.

[0040] As a supplement, the feed end of the pre-cooling box 2 is connected to the discharge end of the screw conveyor 6 via a conduit; freeze-dried matsutake mushrooms are added into the feed inlet 7, and the screw conveyor 6 is started to transport the freeze-dried matsutake mushrooms into the pre-cooling box 2. The freeze-dried matsutake mushrooms roll down along the guide plate 3 until they cover the upper surface of each layer of the guide plate 3, so that they are passively cooled during contact with the guide plate 3, so that the low-temperature pulverization can be carried out later, thereby preserving the active ingredients during pulverization and avoiding the impact of frictional heat generated during pulverization on the quality of matsutake polysaccharide production.

[0041] like Figure 1-3 As shown, the interior of the machine body 1 is provided with a crushing structure, a preliminary crushing implementation structure and a secondary crushing implementation structure from top to bottom. The crushing structure includes a bottom plate fixed to the inner wall of one side of the machine body 1 by bolts, a top support mechanism 401 fixed to the top surface of the bottom plate by bolts, and a spike plate 4 fixed to the extension end of the top support mechanism 401 by bolts.

[0042] Furthermore, the top surface of the bottom plate located below the discharge end of the precooling box 2 is fixed with an inclined plate by bolts, and the bottom surface of the spike plate 4 is in contact with the top surface of the inclined plate.

[0043] Preferably, the top support mechanism 401 is one of an electric telescopic column, a pneumatic cylinder mechanism, or a hydraulic cylinder mechanism.

[0044] Furthermore, the inner wall of the base plate is provided with a feeding port; during operation, the top support mechanism 401 is activated, and the spiked plate 4 is used to reciprocate to squeeze the freeze-dried matsutake mushrooms output from the discharge end of the pre-cooling box 2. Since the matsutake mushrooms are freeze-dried and contain little moisture, they can be hammered and split into several small pieces of different sizes when they come into contact with the spiked plate 4, thus quickly completing the first crushing work of the matsutake mushrooms.

[0045] Furthermore, the bottom outer wall of the base plate is fixed with a hopper 12 by bolts; this facilitates the retention of matsutake mushroom pieces and avoids the accumulation of too many matsutake mushroom pieces on the initial crushing structure, thereby affecting the crushing effect.

[0046] The preliminary crushing implementation structure includes two crushing rollers 11 rotatably connected to the inner wall of one side of the machine body 1, two gears 1401 rotatably connected to the outer wall of one side of the machine body 1, and a drive component. The outer walls of the two gears 1401 mesh with each other, and one end of each gear 1401 is connected to one end of the two crushing rollers 11 through a coupling.

[0047] Furthermore, the drive components include a support plate fixed to one side of the machine body 1 by bolts, a motor 8 fixed to the top surface of the support plate by bolts, a bevel gear assembly 15 connected at one end to the output end of the motor 8 by a coupling, and a transmission belt 14.

[0048] Preferably, the outer wall of the body 1 located outside the gear 1401 is fixed with a shell 5 by bolts;

[0049] Preferably, the bevel gear assembly 15 includes a main gear and a secondary gear meshing on their outer walls. The top end of the secondary gear is rotatably connected to the bottom surface of the machine body 1, and one end of the main gear is rotatably connected to one side of the machine body 1. The transmission belt 14 is sleeved on one of the gears 1401 and one end of the outer wall of the main gear. In use, the control motor 8 is started, which drives the bevel gear assembly 15 to rotate and drives the gear 1401 to rotate via the transmission belt 14. Under their meshing transmission, the two crushing rollers 11 rotate in opposite directions, thereby crushing the matsutake mushroom blocks output from the hopper 12.

[0050] Additionally, the bottom inner wall of the machine body 1 is provided with a crushing chamber 101. The secondary crushing implementation structure includes a crushing roller 10 rotatably connected to the bottom inner wall of the crushing chamber 101, and a transmission belt 9 sleeved on the outer wall of one end of the crushing roller 10 and the outer wall of one end of the auxiliary gear. When the bevel gear assembly 15 is started, the crushing roller 10 is driven to rotate at high speed via the transmission belt 9, thereby crushing the material entering the crushing chamber 101 once again.

[0051] Preferably, the bottom inner wall of the crushing chamber 101 has an inverted conical structure; this facilitates material collection.

[0052] Furthermore, the bottom outer wall of the machine body 1 is fixed with a discharge port 18 by bolts; the crushed matsutake powder is output through the discharge port 18.

[0053] Working principle: Freeze-dried matsutake mushrooms are added to the feed inlet 7. The screw conveyor 6 is started to transport the freeze-dried matsutake mushrooms to the pre-cooling box 2. The freeze-dried matsutake mushrooms roll down along the guide plate 3 until they cover the upper surface of each layer of the guide plate 3, allowing them to be passively cooled during contact with the guide plate 3. The top support mechanism 401 is started, and the spiked plate 4 reciprocates to compress the freeze-dried matsutake mushrooms output from the discharge end of the pre-cooling box 2. Since the matsutake mushrooms are freeze-dried and have low moisture content, they are hammered and broken into several small pieces of varying sizes when they come into contact with the spiked plate 4, which fall into the hopper 12. The motor 8 is started, which drives the bevel gear assembly 15 to rotate, and through the transmission belt 14, the gear 1401 rotates. Under their meshing transmission, the two crushing rollers 11 rotate in opposite directions, thereby compressing and crushing the matsutake mushroom pieces output from the hopper 12. Simultaneously, the crushing roller 10 is driven by the transmission belt 9 to rotate at high speed, thereby further crushing the material that has been crushed by the crushing roller 11 and entered the crushing chamber 101. The crushed matsutake powder is then output through the discharge port 18.
