Description

Technical Field

[0001] The invention relates to the field of pulverizing technology, and in particular to a pulverizing device for producing vegetable and fruit enzymes. Background Art

[0002] In the production of fruit and vegetable enzymes, the crushing device is one of the key equipment. For example, the crushing device for fruit and vegetable enzyme production disclosed in the Chinese patent with publication number CN107913782B is mainly used to crush fresh vegetables, fruits and other plant materials into smaller particles, so that the nutrients and enzyme substances therein are fully released, thereby improving the efficiency of enzyme fermentation and ensuring the uniformity of fermentation, which plays a key role in producing high-quality fruit and vegetable enzymes.

[0003] Existing crushing devices for vegetable and fruit enzyme production usually use a single crushing tool to directly crush the vegetables and fruits. However, due to the different shapes, sizes and textures of vegetables and fruits, it is difficult to ensure that all vegetables and fruits can be evenly crushed into ideal particles by only relying on the crushing tool. At the same time, during the cutting process, a single crushing tool cannot crush larger or harder vegetable and fruit pieces to the appropriate particle size at one time, resulting in different particle sizes in the crushed material, affecting the uniformity and efficiency of subsequent enzyme fermentation.

[0013] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects:

[0014] 1. The crushing device for the production of vegetable and fruit enzymes can realize the preliminary crushing of cooled fruits and vegetables through the main crushing knife assembly, the sub-crushing knife assembly and the heating assembly in the coarse crushing mechanism, wherein the sub-crushing knife assembly is used to crush the fruits and vegetables, and the main crushing knife assembly is used to limit the sub-crushing knife assembly in the crushing structure, and the heating assembly realizes heating of the sub-crushing knife assembly while also providing power for the sub-crushing knife assembly to crush the fruits and vegetables.

The horizontal drive component is used to drive the pusher component to move back and forth horizontally on the grid frame, so that the initially crushed vegetables and fruits are evenly distributed in the grid frame, and the vegetables and fruits are evenly distributed in the crushing knife.

The horizontal drive component is used to drive the pusher component to move back and forth horizontally on the grid frame, and the initially crushed vegetables and fruits can be evenly distributed in the grid frame. This makes the material density of vegetables and fruits at various places similar when entering the crushing link, avoiding the situation where some crushing knives are overloaded and some crushing knives are idle due to uneven material accumulation. Each crushing knife can fully play its role, ensuring the uniformity of crushing, making the particle size after final crushing more consistent, which is conducive to the stable progress of the subsequent enzyme fermentation process.

[0016] 3. The pulverizing device for vegetable and fruit enzyme production can realize cooling treatment of vegetables and fruits before pulverization through the barrier component, air suction component, cooling component and rotating component in the cooling mechanism, wherein the barrier component is used to block the vegetables and fruits before entering the pulverizing device to increase the residence time of the vegetables and fruits in the cooling mechanism, while the air suction component can absorb the cold air generated by the cooling component, and the rotating component can evenly spray the cooling absorbed by the air suction component into the vegetables and fruits, thereby realizing cooling of the vegetables and fruits before pulverization, and the texture of the cooled vegetables and fruits is more uniform. During the pulverizing process, the force of the tool on each part is more consistent, so that it can be more evenly pulverized into smaller particles. Compared with uncooled vegetables and fruits, they will not have different degrees of pulverization due to local over-softness or over-hardness during pulverization, which helps to improve the uniformity of pulverization and provide a better raw material basis for subsequent enzyme fermentation.

[0057] The operating principle of this embodiment is as follows:

[0058] Step 1: First, start the equipment (the equipment in this embodiment refers to: a crushing device for vegetable and fruit enzyme production), and then the staff pours the vegetables and fruits into the cooling box 21 through the dividing funnel 22. The dividing funnel 22 can divide the vegetables and fruits into two parts, and the vegetables and fruits divided into two parts will contact a pair of barrier components 25. After entering the cooling box 21, the vegetables and fruits will directly fall onto the inner arc pieces 252 of the barrier components 25. The inner arc pieces 252 are arranged in a certain arc and connected to each other through partitions 253, forming a plurality of "small basket"-like structures, which can perform preliminary collection and temporary storage of vegetables and fruits, and the support component 27 can fix the inner arc pieces 252 when there is no vegetables and fruits stored. At the same time, the support component 27 can limit the storage and release of vegetables and fruits in the inner arc pieces 252;

[0059] The fixing strip 271 in the support assembly 27 is fixedly connected to the inner wall of the cooling box 21, and the other side of the fixing strip 271 is connected to the friction block 272 through an elastic hinge (the elastic hinge contains elements with elastic deformation ability, such as spring sheets or elastic rubber, etc., which can be elastically deformed when subjected to external force to store energy; when the external force disappears, they can return to their original state and release the stored energy). Under normal circumstances, when there is no or only a small amount of fruits and vegetables in the inner arc sheet 252, the elastic hinge is in a natural state or is only subjected to a small pressure. The elastic hinge provides sufficient support for the inner arc sheet 252 by virtue of its own elastic restoring force and the friction between the friction block 272 and the partition 253, so that the inner arc sheet 252 is kept in a horizontal or nearly horizontal position. The multiple rubber points of the friction block 272 facing the partition 253 further increase the friction force and enhance the stability of the support, ensuring that the fruits and vegetables can be temporarily stored in the inner arc sheet 252 without slipping off prematurely. Once the fruits and vegetables stored in the inner arc sheet 252 continue to increase, the weight of the fruits and vegetables also gradually increases, and the pressure applied to the elastic hinge increases synchronously;

[0060] When the pressure exceeds the elastic limit of the elastic hinge, the elastic element inside the elastic hinge begins to deform significantly. As the deformation of the elastic element further intensifies, the friction between the friction block 272 and the partition plate 253 gradually fails to balance the gravity of the fruits and vegetables. At this time, the friction block 272 begins to rotate downward under the action of the gravity of the fruits and vegetables. The inner arc piece 252 loses the support of the friction block 272 and turns around the rotating rod 251 under the action of the gravity of the fruits and vegetables. The fruits and vegetables on the inner arc piece 252 slide along its arc into the coarse crushing mechanism 3, completing the transfer of materials.

[0061] When the fruits and vegetables in the inner arc piece 252 slide down, the pressure on the elastic hinge is instantly reduced, and the elastic element quickly recovers to a shape and position close to the initial state by virtue of its own elastic restoring force. The friction block 272 is driven by the elastic hinge to return to the position in contact with the partition 253, ready for the collection and temporary storage of the next batch of fruits and vegetables.

[0062] When fruits and vegetables are stored in the inner arc sheet 252, the air holes in the arc box 24 will spray cold air and act on the inner arc sheet 252, and the cold air in the arc box 24 comes from the cooling component 28 (the cooling component 28 is started synchronously when the device is started). As the cooling component 28 is started, the air cooler 281 starts to work and generates low-temperature cold air, which is transported to the two arc boxes 24 through the cold air pipe 282. The amount of cold air transported to the arc box 24 through the cold air pipe 282 is determined by the air suction component 26. The air suction component 26 determines the amount of cold air sucked from the air cooler 281 according to the amount of fruits and vegetables in the inner arc sheet 252 detected by the pressure detector in the support component 27.

[0063] When the cooling component 28 is working, the fan 262 in the air suction component 26 is started synchronously, and the motor of the fan 262 drives the blades to rotate at a high speed, thereby generating a strong suction force, and the cold air delivered by the cold air duct 282 is sucked into the arc box 24. In addition, in order to make the cold air sucked into the arc box 24 be evenly ejected from the air holes of the arc box 24, a rotating component 29 is provided, and a built-in motor is provided in the rotating rod 291 of the rotating component 29, so that the rotating fan blades 292 rotate with the rotation of the rotating rod 291. When the cold air enters the arc box 24, the rotating fan blades 292 evenly stir the cold air and eject it through the multiple air holes opened in the rectangular array on the arc surface of the arc box 24. The ejected cold air surrounds the inner arc blade 2 The fruits and vegetables on the inner arc piece 252 are quickly cooled. During the cooling process, since the inner arc piece 252 is rotatably connected to the rotating rod 251, the weight distribution of the fruits and vegetables changes and the slight vibration during the cooling process and other factors will cause the inner arc piece 252 to flexibly rotate within a certain range, ensuring that all parts of the fruits and vegetables can fully contact the cold air to achieve uniform cooling. Cooling the fruits and vegetables can make the texture of the fruits and vegetables more uniform. During the crushing process, the force of the cutter on each part is more consistent, so that they can be more evenly crushed into smaller particles. Compared with uncooled fruits and vegetables, they will not have different crushing degrees due to partial oversoftness or overhardness during crushing, which helps to improve the uniformity of crushing and provide a better raw material basis for subsequent enzyme fermentation.

[0064] At the same time, the arc-shaped plates 23 around the top wall of the cooling box 21 play a role in limiting the diffusion direction of the cold air, so that the cold air is mainly concentrated inside the cooling box 21, and will not be discharged in large quantities from the dividing funnel 22. The reason for cooling the fruits and vegetables before crushing is that: cooling can make the texture of the fruits and vegetables more conducive to the crushing operation, increase their hardness and reduce their cell permeability, thereby improving the crushing efficiency, making it easier for the knife to cut in and reducing the situation where the fruits and vegetables stick to the knife, making the crushing process smoother and more efficient.

[0065] Step 2: When the fruits and vegetables cooled by the cooling mechanism 2 enter the coarse crushing mechanism 3 for preliminary crushing, since the position of the pair of openings on the positioning plate 32 at the top of the coarse crushing box 31 accurately corresponds to the barrier component 25, when the fruits and vegetables fall from the cooling box 21, they will accurately enter the corresponding coarse crushing area through the openings on the positioning plate 32. The coarse crushing area is composed of a mother crushing knife component 33 and a pair of sub-crushing knife components 35. Through the mutual cooperation of a mother crushing knife component 33 and a pair of sub-crushing knife components 35, the cooled fruits and vegetables can be preliminarily processed into relatively small and more uniform pieces. Compared with direct overall crushing, this preliminary crushing avoids the influence of the large difference in size and texture of fruits and vegetables on subsequent crushing, and lays the foundation for subsequent crushing to obtain a more ideal particle size. The mother crushing knife component 33 is located at the center of the coarse crushing area, and the two sub-crushing knife components 35 are symmetrically distributed on both sides of the mother crushing knife component 33. Such a layout is conducive to all-round crushing of fruits and vegetables.

[0066] The fixed box 341 of the heating assembly 34 is connected to the inner walls of the coarse crushing box 31 on both sides by sliding, so as to realize horizontal reciprocating sliding in the coarse crushing box 31, and the multiple first hydraulic rods 342 and multiple heaters 343 alternately fixedly connected on the inner wall of the fixed box 341 start to work accordingly. The first hydraulic rod 342 performs telescopic movement under the control of the controller (the entire device is controlled by the controller), thereby driving the fixed box 341 to slide back and forth, and the reciprocating sliding of the fixed box 341 also synchronously drives the sub-crushing knife assembly 35 to slide. When the first hydraulic rod 342 telescopes, the heater 343 also starts to work, thereby continuously generating heat, thereby realizing heating of the first hydraulic rod 342 and the sub-crushing knife assembly 35 connected thereto, and because the first hydraulic rod 342 is always one more than the heater 343, this difference in quantity enables the heaters 343 to be evenly distributed between the first hydraulic rods 342, so that the heat generated by each heater 343 can be transmitted to the adjacent first hydraulic rods 342 The heat can be transferred to the first hydraulic rod 342 to avoid the cold air after the fruits and vegetables are cooled, thereby preventing the normal operation of the first hydraulic rod 342 from being affected. At the same time, since the number of the first hydraulic rods 342 is large and the distribution is balanced, the heat can be more evenly distributed to each first hydraulic rod 342 to avoid local overheating or overcooling. At the same time, the multiple first hydraulic rods 342 affect each other and restrict each other during the process of thermal expansion or cooling contraction, maintaining a relatively stable structural state, thereby ensuring the uniformity of the temperature change of the first hydraulic rod 342 during the heating process and the stability of the entire structure, further ensuring the normal operation of the coarse crushing mechanism, thereby ensuring the uniformity and stability of heating, effectively preventing the sub-crushing knife assembly 35 from being affected by cold air when crushing the cooled fruits and vegetables, and ensuring the normal working performance of the sub-crushing knife assembly 35.

[0067] Reasons for heating the first hydraulic rod 342 and the sub-crushing knife assembly 35:

[0068] The temperature of the fruits and vegetables is relatively low after being cooled by the cooling mechanism 2. When the sub-crushing knife assembly 35 directly contacts the low-temperature fruits and vegetables for crushing, the sub-crushing knife assembly 35 and its related connecting parts (such as the first hydraulic rod 342) will cool down rapidly. In a low-temperature environment, the toughness of metal materials will decrease, becoming more brittle and easy to break. By heating the sub-crushing knife assembly 35 and the first hydraulic rod 342 through the heating assembly 34, they can be maintained in a relatively suitable temperature range, maintaining good toughness and strength, so that they can withstand the impact force and friction during the crushing process, reduce the risk of component damage due to low temperature, and extend the service life of the equipment.

[0069] The second fixed plate 351 in the sub-crushing knife assembly 35 is divided into a crushing area and a pushing and crushing area. When the fruits and vegetables enter the coarse crushing area, the main crushing knife 332 and the sub-crushing knife 352 cut and crush the fruits and vegetables at the same time. The main crushing knife 332 mainly restricts the sub-crushing knife 352 and crushes the fruits and vegetables. The sub-crushing knife 352 uses its sharp blade and appropriate arrangement to crush the fruits and vegetables. In the crushing process, the fruits and vegetables are gradually broken into blocks under the joint action of the main crushing knife 332 and the sub-crushing knife 352, and the fruits and vegetables that have been initially crushed fall onto the porous screening plate 36. The aperture of the holes on the porous screening plate 36 can be customized according to user needs. The vegetables and fruits that have been initially crushed can smoothly pass through the small holes on the porous screening plate 36 to enter the fine crushing mechanism 4. For the vegetables and fruits that are not completely crushed, the push knife 353 in the sub-crushing knife assembly 35 will push these larger-sized vegetables and fruits to the vicinity of the main crushing knife 332 during the sliding process of the fixed box 341, and further crush them by the squeezing and cutting action between the main crushing knife 332 and the push knife 353 until they can pass through the porous screening plate 36 and enter the fine crushing mechanism 4, thereby completing the initial crushing of the vegetables and fruits.

[0070] Step 3: The fruits and vegetables that have completed the initial crushing will enter the fine crushing box 41 in the fine crushing mechanism 4 for final crushing. When the initially crushed fruits and vegetables enter the fine crushing box 41 (hereinafter referred to as the initially crushed fruits and vegetables A), the fruits and vegetables A first fall on the grid frame 42, and the horizontal drive component 43 and the push component 44 cooperate with each other to evenly distribute the fruits and vegetables A on the grid frame 42, and at the same time, it can also prevent the fruits and vegetables A from being blocked in the grid of the grid frame 42, and can evenly distribute the initially crushed fruits and vegetables in the grid frame 42. This makes the density of materials at various places similar when the fruits and vegetables enter the crushing stage, avoiding the situation where some crushing knives 45 are overloaded and some crushing knives 45 are idle due to uneven material accumulation, and then each crushing knife 45 can fully play its role, ensuring the uniformity of crushing, making the particle size after final crushing more consistent, which is conducive to the stable progress of the subsequent enzyme fermentation process.

[0071] Among them, the horizontal driving component 43 is mainly composed of a sliding box 431, an expansion piece 432 and a horizontal slider 433. Since the horizontal slider 433 itself has a driver and a distance detector, the horizontal slider 433 starts to reciprocate in the sliding box 431 (the reciprocating trajectory and speed of the horizontal slider 433 can be customized by the user in the controller according to actual conditions). When the horizontal slider 433 moves horizontally in the sliding box 431, it is transmitted to the pusher component 44 through the connecting column 443 connected thereto. One end of the connecting column 443 is fixedly connected to the horizontal slider 433, and the other end passes through the expansion piece 432 and is fixedly connected to the connecting plate 441 of the pusher component 44. In this way, the reciprocating linear motion of the horizontal slider 433 is converted into The pushing assembly 44 moves back and forth horizontally above the grid frame 42. At the same time, the telescopic piece 432 can prevent the fruits and vegetables A from entering the sliding box 431 and ensure the smooth sliding of the horizontal slider 433. The telescopic piece 432 is made of flexible and wear-resistant material, well sealed with the opening edge of the fine crushing box 41 and adapted to the movement trajectory of the horizontal slider 433. When the device is running, it fits tightly and moves with the horizontal slider 433 to expand and contract, effectively blocking the splashed or pushed materials in the crushing process from entering the sliding box 431, avoiding the interference of materials with the movement of the horizontal slider 433, and ensuring that the horizontal slider 433 can slide back and forth stably and smoothly in the sliding box 431, thereby ensuring the normal operation of the entire horizontal driving assembly 43 and even the fine crushing mechanism 4.

[0072] Among them, when the pushing component 44 moves horizontally back and forth, its arc cover 442 is designed in an arc shape, and its curvature is adapted to the shape of the grid frame 42. When the pushing component 44 moves, the arc cover 442 can effectively disperse the fruits and vegetables A to prevent the fruits and vegetables A from piling up on the top of the pushing component 44. As the pushing component 44 moves, the connecting plate 441 drives the brush 444 to move on the surface of the grid frame 42. The bristles of the brush 444 are soft and have a certain elasticity, and can penetrate into the grid of the grid frame 42 to gently comb and push the fruits and vegetables A accumulated in the grid, so that the fruits and vegetables A are evenly distributed on the grid frame 42. Through the continuous reciprocating movement of the brush 444 in the pushing component 44, the fruits and vegetables A can pass through the grid of the grid frame 42 and enter the crushing knife 45 of the fine crushing box 41. The crushing knife 45 is responsible for the final crushing of the fruits and vegetables A, thereby completing the crushing requirements for the production of fruit and vegetable enzymes.

[0073] The crushing knives 45 are powered by a motor disposed on the side of the fine crushing box 41 and are installed on the inner wall of the fine crushing box 41 through transmission components such as bearings and tracks, thereby driving the crushing knives 45 to rotate synchronously at high speed (driving components such as motors, bearings, tracks, etc. are common in the prior art and are therefore not shown in the figure).

[0074] When the brush 444 pushes the fruits and vegetables A, the object detector 447 on the pushing assembly 44 continuously monitors the grid condition of the grid frame 42. The object detector 447 uses infrared sensor detection technology to accurately detect whether there are fruits and vegetables A stuck in the grid. Once the object detector 447 detects that there is a material stuck in the grid, it will immediately transmit a signal to the controller, and the controller will control the second hydraulic rod 445 to perform a telescopic action according to the signal instruction. Each group of the second hydraulic rods 445 has at least two, which are jointly connected to the force plate 446 to ensure that the force plate 446 remains stable during the telescopic process. The cutter 448 on the force plate 446 is accurately inserted into the grid under the push of the second hydraulic rod 445 to cut and crush the fruits and vegetables A stuck in the grid, so that the fruits and vegetables A can continue to pass through the grid smoothly and enter the action area of ​​the crushing knife 45, preventing material blockage from affecting the crushing process. At the same time, the cutter 448 is consistent with the grid gap specification of the grid frame 42, ensuring that the cutter 448 can effectively clean the blockage in the grid and will not damage the grid frame 42.

[0075] After being fully crushed by the crushing knife 45, the fruits and vegetables fall into the collecting hopper 46 at the bottom of the fine crushing box 41 through the grid frame 42 under the action of gravity, and the crushed materials are collected and guided to the discharge pipe 47. The crushed fruits and vegetables are discharged through the discharge pipe 47 and enter the subsequent production process such as enzyme fermentation, providing suitable raw materials for the production of enzymes.
