Description

TECHNICAL FIELD

[0001] The present application relates to coffee bean processing equipment technical field, specifically to a self-circulation type coffee bean crushing and drying integrated machine. BACKGROUND

[0002] The self-circulation type coffee bean crushing and drying integrated machine aims to realize the automatic equipment from the raw material drying treatment to the whole process of crushing, which integrates the crushing and drying process. The biggest advantage of this integrated machine is to simplify the process, improve the efficiency, reduce the labor and site cost. When crushing coffee beans, dried coffee beans after peeling are often used for processing. However, during the transportation and storage of coffee beans, the coffee beans may appear to be re-hydrated, and the moisture in the coffee beans may increase again. Therefore, before crushing, the coffee beans usually need to be dried again, and after the coffee beans are cooled, they are crushed.

[0003] When the crusher crushes coffee beans, it often relies on rotating hammers to impact the coffee beans to crush the coffee beans. The rotating hammers will generate strong airflow in the crushing cavity. The larger particles are less affected by the airflow due to their large mass and will be impacted by the hammers. However, the required coffee powder is relatively fine. When the large particles are crushed into smaller particles, the mass is very light and may follow the airflow. Part of the smaller particles may only be suspended and rotated in the cavity, which is difficult to be impacted by the hammers, affecting the crushing efficiency. SUMMARY

[0004] To solve the above technical problems, the present application provides a self-circulation type coffee bean crushing and drying integrated machine, which comprises a support table, two conveying cylinders are fixedly connected to the inner wall of the support table, and a spiral auger is rotatably connected to the inner wall of each conveying cylinder.

A crushing mechanism is fixedly arranged on the top of the support table and used for crushing coffee beans. A rolling mechanism is slidingly arranged on the inner wall of the crushing mechanism and used for extruding the crushed coffee bean particles. An acceleration mechanism is slidingly arranged on the inner wall of the crushing mechanism and used for accelerating the discharge speed of the powder. When in use, the operator pours the coffee beans to be crushed into the feed inlet, and the coffee beans enter the conveying cylinder located at the top along the feed inlet. Then, the two motors are started, and the motor located at the top drives the spiral auger located at the top to rotate clockwise, and the motor located at the bottom drives the spiral auger located at the bottom to rotate counterclockwise. When the spiral auger located at the top rotates, it will transport the coffee beans away from the feed inlet. After starting the hot air blower and the cold air blower through the air pipe one and the air pipe two, the air pipe one sends hot air into the conveying cylinder at the top, the air pipe two sends cold air into the conveying cylinder at the bottom, the hot air in the conveying cylinder at the top dries the coffee beans in it again, with the continuous conveying of the coffee beans by the spiral auger at the top, the coffee beans in the conveying cylinder at the top fall into the conveying cylinder at the bottom, when the spiral auger at the bottom rotates, it conveys the coffee beans to move towards the feeding pipe, the cold air in the conveying cylinder at the bottom cools and cools the dried coffee beans.

[0007] Preferably, the accelerating mechanism comprises: The flow dividing assembly is fixedly arranged on the side wall of the crushing disc; The discharging assembly is fixedly arranged on the inner wall of the crusher shell through the connecting member; The connecting member comprises a connecting frame fixedly connected to the inner wall of the crusher shell, and the inner wall of the connecting frame is slidably connected with an inclined piston plate; When the coffee beans enter the crusher shell, the flow direction of the coffee beans is changed by the flow dividing assembly, and the moving speed of the coffee beans is accelerated, so that the coffee beans impact the crushing assembly, and the discharging speed of the coffee bean powder is accelerated by the discharging assembly.

[0008] Preferably, the feeding assembly comprises a feeding pipe connected through the inner wall of the crusher shell, and the side wall of the crusher shell is fixedly connected with a second motor.

[0009] Preferably, the crushing assembly comprises an arc-shaped sieve plate fixedly connected at the inner wall of the pulverizer shell, and the output end side wall of the motor two is fixedly connected with the side wall of the pulverizing disc; Wherein, as the spiral auger at the bottom continuously conveys the coffee beans, the coffee beans will fall into the feeding pipe, at this time, the coffee beans enter the pulverizer shell along the feeding pipe, by starting the motor two to drive the pulverizing disc to rotate, when the pulverizing disc rotates, it will impact the coffee beans, so that they are crushed into small pieces, at the same time, the fast rotating speed of the pulverizing disc will also throw the coffee beans to the inner wall of the pulverizer shell.

[0010] Preferably, the extrusion assembly comprises a crushing disc two fixedly connected at the inner wall of the pulverizer shell, and twelve grooves one are formed at the side wall of the crushing disc one, and six crushing blocks are arranged at the side wall of the crushing disc two; The side wall of the six crushing blocks is fixedly connected with the side wall of the six spring return rods, and the side wall of the six crushing blocks is slidingly connected with the inner wall of the pulverizing disc; Wherein, the coffee beans thrown to the inner wall of the pulverizer shell will pass through the gap between the pulverizing disc and the crushing disc one and the crushing disc two, so that the coffee bean particles are extruded and crushed, and the coffee powder that meets the crushing standard will be screened out through the arc-shaped sieve plate, and the spring return rod and the crushing block will also rotate when the pulverizing disc rotates; When the spring return rod rotates, it will move along the groove one arc surface, when the spring return rod separates from the groove one and contacts the crushing disc one, the spring return rod will be extruded, driving the crushing block to move towards the crushing disc two, so as to accumulate the elastic force of the spring return rod, with the continuous rotation of the pulverizing disc, when the spring return rod moves to the position of the groove one again, the elastic force of the spring return rod will be released, so that the spring return rod and the crushing block return to the original position; Until the spring return rod contacts the crushing disc one again and is extruded to move, so as to reciprocate, the crushing block will move transversely while rotating, when the crushing block transversely reciprocates and contacts the smaller coffee bean particles, through the convex points on the surface thereof, the crushing block will exert transverse shear force and friction grinding force on the smaller particles, further tearing and crushing the fine particles, accelerating the formation of the required powder particles, improving the uniformity of the crushed particles, effectively preventing the airflow generated when the pulverizing disc rotates from carrying the smaller particles to rotate, which is difficult to impact the smaller particles, which is easy to cause the coffee bean crushing speed to be slow, thereby improving the crushing efficiency.

[0011] Preferably, the reciprocating assembly comprises five grooves two formed on the side of the pulverizing disc away from the motor two, and a sliding frame is slidingly connected at the inner wall of the pulverizer shell; A spring rod is fixedly connected at the side of the pulverizer shell away from the motor two, and the outer wall of the spring rod is slidingly connected with the inner wall of the sliding frame; When the second groove and the sliding frame are separated, the sliding frame is extruded and moves away from the second motor during the process of the sliding frame contacting the crushing disc, and the sliding frame extrudes the spring rod to accumulate the elastic force of the spring rod.

[0012] Preferably, the shunt assembly comprises a connecting cylinder fixedly connected to the side of the crushing disc away from the second motor, and an annular stopper is slidingly connected to the outer wall of the connecting cylinder, and the bottom of the annular stopper is fixedly connected to the outer wall of the sliding frame. When the coffee beans enter the crushing machine shell through the feeding pipe, the coffee beans first enter the connecting cylinder, and the coffee beans in the connecting cylinder are affected by the centrifugal force generated by the rotation of the connecting cylinder and contact the inner wall of the connecting cylinder to rotate with the connecting cylinder. When the sliding frame moves, the annular stopper moves to change the position of the annular stopper and cancel the blocking of the coffee beans in the connecting cylinder. At this time, the coffee beans are affected by the centrifugal force of the connecting cylinder, and the coffee beans are thrown out and move towards the crushing disc at a faster speed, changing the impact mode of the coffee beans. The impact force comes not only from the rotating force of the crushing disc, but also from the active impact of the coffee beans. The sum of the two forces makes the coffee beans receive greater impact force and be more easily broken into smaller particles. This effectively prevents multiple coffee beans from falling and contacting the crushing disc at the same time. Due to the time difference in the falling process, some particles will rebound after impacting the crushing disc, impacting other particles, which will consume part of the impact force and reduce the speed of breaking the coffee beans into small particles.

[0013] Preferably, the discharge assembly comprises a connecting rod rotationally connected to the bottom of the inclined piston plate, and a connecting frame is arranged on the side wall of the crushing machine shell. The bottom of the inclined piston plate is slidingly connected to the inner wall of the crushing machine shell, and a sealing strip is fixedly connected to the outer wall of the inclined piston plate. The side wall of the connecting frame is fixedly connected to the side wall of the sliding frame, and the inner wall of the connecting rod is rotationally connected to the side wall of the connecting frame. When the sliding frame moves, the connecting frame is also moved, the connecting frame pulls the connecting rod to rotate, and the inclined piston plate is lowered through the connecting rod. Since the crushing disc rotates at a high speed, the sliding frame moves at a high speed, and the inclined piston plate quickly descends. Since the outer wall of the inclined piston plate is tightly attached to the inner wall of the connecting frame through the sealing strip, the space at the top of the inclined piston plate rapidly increases when the inclined piston plate quickly descends, resulting in a local negative pressure in the connecting frame. In order to balance the pressure difference, the atmosphere rapidly flows into the connecting frame through the screen holes of the arc-shaped screen plate. During the gas supplement process, the gas pushes the powder at the top of the connecting frame to fall into the top of the inclined piston plate, accelerating the discharge speed of the crushed powder and creating space for the crushing of new materials.

[0014] The present application has the following advantages: (1) The coffee beans to be crushed are poured into the feed inlet by the operator during use of the application, and the coffee beans are dried and cooled again by the hot air blower and the cold air blower, and then enter the crushing machine shell through the feed pipe, and the crushing disc is driven to rotate by starting the motor II, and when the crushing disc rotates, it will impact the coffee beans, so that the coffee beans are crushed into small pieces under the impact force, and when the crushing disc rotates, the spring reset rod and the crushing block are also driven to rotate, and the crushing block is moved transversely and reciprocatingly while being squeezed by the squeezing assembly, and when the crushing block transversely and reciprocatingly contacts the smaller coffee bean particles, it will exert transverse shearing force and friction grinding force on the smaller particles, further tearing and crushing the fine particles, accelerating the formation of the required powder particles, improving the uniformity of the crushed particles, and effectively preventing the airflow generated during rotation of the crushing disc from carrying smaller particles to rotate, which is difficult to impact the smaller particles and easy to cause slow crushing of the coffee beans, thereby improving the crushing efficiency.

[0015] (2) When the coffee beans enter the crushing machine shell through the feed pipe, the coffee beans will first enter the connecting cylinder, and when the crushing disc rotates, it will drive the connecting cylinder to rotate, and the coffee beans in the connecting cylinder will be affected by the centrifugal force generated by the rotation of the connecting cylinder and will contact the inner wall of the connecting cylinder and rotate with the connecting cylinder, and when the crushing disc rotates, the position of the annular stopper is changed by the reciprocating assembly to cancel the blocking of the coffee beans in the connecting cylinder, and at this time, the coffee beans are affected by the centrifugal force of the connecting cylinder and are thrown out to move towards the crushing disc at a faster speed, which is more likely to crush the coffee beans into smaller particles, and effectively prevents the multiple coffee beans from falling and contacting the crushing disc at the same time, and due to the time difference in the falling process, some particles will rebound after impacting the crushing disc, impact other particles, consume part of the impact force, and reduce the speed of crushing the coffee beans into small particles.

[0016] (3) When the sliding frame moves, the inclined piston plate rapidly descends through the discharge assembly, which rapidly increases the space at the top of the inclined piston plate, resulting in the formation of local negative pressure in the connecting frame, and the outside atmosphere will rapidly flow into the connecting frame through the screen holes in order to balance the pressure difference, and in the process of gas replenishment, the gas will push the powder at the top of the connecting frame to fall onto the top of the inclined piston plate until the inclined piston plate separates from the connecting frame, and the coffee powder will flow out through the slope of the inclined piston plate, rapidly discharging the coffee powder and accelerating the discharge speed of the crushed powder, effectively preventing the crushing speed of the coffee beans from being accelerated, and the screen holes of the arc-shaped sieve plate are small, and the crushed coffee powder is more, which is difficult to rapidly discharge, and a large amount of powder will accumulate in the crushing machine shell, which may be subjected to multiple transverse extrusions by the crushing block, easily causing part of the powder to be extruded too finely, affecting the uniformity of the crushed particle size.

[0017] (4) The present application significantly reduces the residence time of coffee beans in the crusher shell during the process of crushing coffee beans into powder and accelerating the discharge speed of the powder, reduces the high temperature generated when crushing coffee beans, and effectively prevents the aroma of the coffee powder from being easily volatilized due to the high temperature generated when the crushing disc crushes coffee beans, thereby better preserving the aroma of the coffee powder.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0022] Embodiment one, please refer to Figures 1-4 The present application is a self-circulation type coffee bean crushing and drying all-in-one machine, which comprises a support table 13, two conveying cylinders 14 are fixedly connected to the inner wall of the support table 13, spiral augers 15 are rotatably connected to the inner walls of the two conveying cylinders 14, two motor ones 16 are fixedly connected to the side walls of the support table 13, and the output end side walls of the two motor ones 16 are fixedly connected to the side walls of the two spiral augers 15; A hot air blower 17 is fixedly connected to the inner wall of the support table 13, and a cold air blower 18 is fixedly connected to the inner wall of the support table 13; The crushing mechanism 1 is fixedly arranged at the top of the support table 13 and is used for crushing coffee beans; The rolling mechanism 2 is slidingly arranged at the inner wall of the crushing mechanism 1 and is used for extruding the crushed coffee bean particles; The acceleration mechanism 3 is slidingly arranged at the inner wall of the crushing mechanism 1 and is used for accelerating the discharge speed of the powder; When in use, the operator pours the coffee beans to be crushed into the feeding port, such as Figure 1As shown in the position of G, the coffee beans will enter the conveying cylinder 14 at the top through the feed inlet, and then start two motors 16, so that the motor 16 at the top drives the spiral auger 15 at the top to rotate clockwise, and the motor 16 at the bottom drives the spiral auger 15 at the bottom to rotate counterclockwise. When the spiral auger 15 at the top rotates, it will convey the coffee beans away from the feed inlet; Then start the hot air blower 17 and the cold air blower 18 through the air pipe one and the air pipe two, so that the air pipe one conveys hot air into the conveying cylinder 14 at the top, and the air pipe two conveys cold air into the conveying cylinder 14 at the bottom, as shown in the position of H and I. Figure 3 As shown in the position of H and I, the hot air in the conveying cylinder 14 at the top will dry the coffee beans inside again. With the continuous conveying of the coffee beans by the spiral auger 15 at the top, the coffee beans in the top conveying cylinder 14 will fall into the conveying cylinder 14 at the bottom. When the spiral auger 15 at the bottom rotates, it will convey the coffee beans to move towards the feed pipe 112 direction, into the bottom conveying cylinder 14. The cold air in the bottom conveying cylinder 14 will cool the dried coffee beans.

[0023] The crushing mechanism 1 comprises: The feed assembly 11 is fixedly arranged on the top of the support table 13 through a fixing member; The fixing member comprises a crusher shell 111 fixedly connected to the top of the support table 13; The crushing assembly 12 is rotatably arranged on the inner wall of the crusher shell 111 through a rotating member; The rotating member comprises a crushing disc 121 rotatably connected to the inner wall of the feed assembly 11; The coffee beans that are dried and cooled again will enter the crusher shell 111, and then the coffee beans will be crushed by the crushing assembly 12.

[0024] The crushing mechanism 2 comprises: The extrusion assembly 21 is slidably arranged on the inner wall of the crushing disc 121 through a sliding member; The sliding member comprises six spring return rods 213 slidably connected to the inner wall of the crushing disc 121, and the inner wall of the crusher shell 111 is fixedly connected with a crushing disc one 211; The reciprocating assembly 22 is slidably arranged on the inner wall of the crusher shell 111; When the crushing assembly 12 crushes the coffee beans, the extrusion assembly 21 moves transversely and reciprocally to extrude smaller coffee bean particles.

[0025] The acceleration mechanism 3 comprises: The flow dividing assembly 31 is fixedly arranged on the side wall of the crushing disc 121; The discharge assembly 32 is fixedly arranged at the inner wall of the pulverizer shell 111 through a connecting piece; The connecting piece comprises a connecting frame 321 fixedly connected at the inner wall of the pulverizer shell 111, and a beveled piston plate 322 slidingly connected at the inner wall of the connecting frame 321; When the coffee beans enter the pulverizer shell 111, the flow direction of the coffee beans is changed by the flow distribution assembly 31, and the moving speed of the coffee beans is accelerated, so that the coffee beans impact the breaking assembly 12, and the discharge speed of the coffee bean powder is accelerated by the discharge assembly 32.

[0026] In example two, please refer to Figures 3-10 The present application is a self-circulating coffee bean crushing and drying all-in-one machine. Based on example one, the feeding assembly 11 comprises a feeding pipe 112 connected through the inner wall of the pulverizer shell 111, and a motor two 113 fixedly connected at the side wall of the pulverizer shell 111.

[0027] The breaking assembly 12 comprises an arc-shaped sieve plate 122 fixedly connected at the inner wall of the pulverizer shell 111, and the output end side wall of the motor two 113 is fixedly connected with the side wall of the pulverizing disc 121; When the bottom spiral auger 15 continuously conveys the coffee beans, the coffee beans will fall into the feeding pipe 112. At this time, the coffee beans enter the pulverizer shell 111 through the feeding pipe 112, and the pulverizing disc 121 is driven to rotate by starting the motor two 113. When the pulverizing disc 121 rotates, it will impact the coffee beans, causing them to be crushed into small pieces. At the same time, the fast rotating speed of the pulverizing disc 121 will also throw the coffee beans towards the inner wall of the pulverizer shell 111.

[0028] The extrusion assembly 21 comprises a breaking disc two 215 fixedly connected at the inner wall of the pulverizer shell 111, and twelve grooves one 212 are formed in the side wall of the breaking disc one 211. Six breaking blocks 214 are arranged at the side wall of the breaking disc two 215; The side wall of the six breaking blocks 214 is fixedly connected with the side wall of the six spring return rods 213, and the side wall of the six breaking blocks 214 is slidingly connected with the inner wall of the pulverizing disc 121; The coffee beans thrown towards the inner wall of the pulverizer shell 111 will pass through the gap between the pulverizing disc 121 and the breaking disc one 211 and the breaking disc two 215, so that the coffee bean particles are extruded and broken. The coffee powder that meets the crushing standard will be screened and discharged through the arc-shaped sieve plate 122. When the pulverizing disc 121 rotates, it will also drive the spring return rod 213 and the breaking block 214 to rotate; When the spring return rod 213 rotates, it moves along the arc surface of the first groove 212. When the spring return rod 213 separates from the first groove 212 and comes into contact with the first crushing disc 211, the spring return rod 213 will be squeezed, causing the crushed block 214 to move towards the second crushing disc 215, allowing the spring return rod 213 to accumulate rebound force. As the crushing disc 121 continues to rotate, when the spring return rod 213 moves back to the position of the first groove 212, the rebound force of the spring return rod 213 will be released, causing the spring return rod 213 and the crushed block 214 to return to their original positions. Until the spring return rod 213 contacts the crushing disc 211 again and is squeezed and moved, this process repeats. Simultaneously, the crushed block 214 moves laterally during rotation. When the crushed block 214 moves laterally and comes into contact with smaller coffee bean particles, it passes through the protrusions on its surface, such as... Figure 6 As shown in the position of J, a lateral shearing force and frictional grinding force will be applied to the smaller particles, further tearing and breaking the fine particles, accelerating the formation of the required powder particles, improving the uniformity of the crushed particles, and effectively preventing the airflow generated when the crushing disc 121 rotates from carrying smaller particles along with the rotation, making it difficult to collide with smaller particles, which would easily cause the coffee bean crushing speed to be slow, thereby improving the crushing efficiency.

[0029] The reciprocating assembly 22 includes five grooves 221 formed on the side of the crushing disc 121 away from the motor 113, and a sliding frame 222 is slidably connected to the inner wall of the crusher housing 111. A spring rod 223 is fixedly connected to the side of the crusher housing 111 away from the motor 113, and the outer wall of the spring rod 223 is slidably connected to the inner wall of the sliding frame 222. When the crushing disc 121 rotates, the contact position between the groove 221 and the sliding frame 222 will change. When the groove 221 separates from the sliding frame 222, the sliding frame 222 will be squeezed and move away from the motor 113 during the process of contact between the sliding frame 222 and the crushing disc 121. The sliding frame 222 will also squeeze the spring rod 223, causing the spring rod 223 to accumulate rebound force.

[0030] The diversion assembly 31 includes a connecting cylinder 311 fixedly connected to the side of the crushing disc 121 away from the motor 213. An annular stop 312 is slidably connected to the outer wall of the connecting cylinder 311. The bottom of the annular stop 312 is fixedly connected to the outer wall of the sliding frame 222. Wherein, when the coffee beans enter the crushing machine shell 111 through the feeding pipe 112, the coffee beans will first enter the connecting cylinder 311, and when the crushing disc 121 rotates, it will drive the connecting cylinder 311 to rotate, and the coffee beans in the connecting cylinder 311 will be affected by the centrifugal force generated by the rotation of the connecting cylinder 311 and will contact the inner wall of the connecting cylinder 311 and rotate with the connecting cylinder 311. When the sliding frame 222 moves, it will drive the annular block 312 to move and change the position of the annular block 312, canceling the blocking of the coffee beans in the connecting cylinder 311. At this time, the coffee beans will be affected by the centrifugal force of the connecting cylinder 311 and will be thrown out and move towards the crushing disc 121 at a faster speed, changing the impact mode of the coffee beans. The impact force not only comes from the rotational force of the crushing disc 121, but also from the active impact of the coffee beans themselves. The sum of the two forces will make the coffee beans receive greater impact force and be more easily broken into smaller particles, effectively preventing multiple coffee beans from falling and contacting the crushing disc 121 at the same time. Due to the time difference in the falling process, some particles will rebound after impacting the crushing disc 121, impacting other particles and consuming part of the impact force, reducing the speed of breaking the coffee beans into small particles.

[0031] The discharge assembly 32 includes a connecting rod 324 rotatably connected to the bottom of the inclined piston plate 322. The side wall of the crushing machine shell 111 is provided with a connecting frame 323. The bottom of the inclined piston plate 322 is slidably connected to the inner wall of the crushing machine shell 111. The outer wall of the inclined piston plate 322 is fixedly connected with a sealing strip; The side wall of the connecting frame 323 is fixedly connected with the side wall of the sliding frame 222. The inner wall of the connecting rod 324 is rotatably connected with the side wall of the connecting frame 323. Wherein, when the sliding frame 222 moves, it will also drive the connecting frame 323 to move, the connecting frame 323 will pull the connecting rod 324 to rotate, and the inclined piston plate 322 will be pulled down by the connecting rod 324. Because the speed of the crushing disc 121 rotating is fast, the speed of the extrusion sliding frame 222 moving is also fast, which will make the inclined piston plate 322 quickly descend. Because the outer wall of the inclined piston plate 322 is tightly attached to the inner wall of the connecting frame 321 through the sealing strip, when the inclined piston plate 322 quickly descends, the space at the top of the inclined piston plate 322 will rapidly increase, causing a local negative pressure in the connecting frame 321. The outside atmosphere will quickly flow into the connecting frame 321 through the screen holes of the arc-shaped screen plate 122 in order to balance the pressure difference. In the process of gas supplement, the gas will push the powder at the top of the connecting frame 321 to fall into the top of the inclined piston plate 322, accelerating the discharge speed of the crushed powder and creating space for the crushing of new materials.

[0032] The number of the above-mentioned assemblies is not limited, and those skilled in the art can freely set according to actual needs, as long as the above-mentioned assemblies are installed at the connecting position of the corresponding assemblies.

[0033] One specific application of this embodiment is that when the present application is used, the operator pours the coffee beans to be pulverized into the feed inlet, such as Figure 1 As shown in the position of Fig. 2G, the coffee beans will enter the top conveying cylinder 14 along the feed inlet, and then the two motors 16 are started, the top motor 16 drives the top auger 15 to rotate clockwise, and the bottom motor 16 drives the bottom auger 15 to rotate counterclockwise, when the top auger 15 rotates, it will transport the coffee beans away from the feed inlet; Then the hot air blower 17 and the cold air blower 18 are started to pass through the air conveying pipe 1 and the air conveying pipe 2, the air conveying pipe 1 transports hot air into the top conveying cylinder 14, and the air conveying pipe 2 transports cold air into the bottom conveying cylinder 14, such as Figure 3 As shown in the positions of Fig. 2H and 2I, the hot air in the top conveying cylinder 14 will dry the coffee beans inside again, and as the top auger 15 continues to transport the coffee beans, the coffee beans in the top conveying cylinder 14 will fall into the bottom conveying cylinder 14, when the bottom auger 15 rotates, it will transport the coffee beans to move towards the feed pipe 112, the cold air in the bottom conveying cylinder 14 will cool the dried coffee beans, and as the bottom auger 15 continues to transport the coffee beans, the coffee beans will fall into the feed pipe 112; At this time, the coffee beans enter the pulverizer shell 111 along the feed pipe 112, and the motor 2 113 is started to drive the pulverizing disc 121 to rotate, when the pulverizing disc 121 rotates, it will impact the coffee beans, so that they are pulverized into small pieces, at the same time, the fast rotating speed of the pulverizing disc 121 will also throw the coffee beans to the inner wall of the pulverizer shell 111, so that part of the coffee bean particles pass through the gap between the pulverizing disc 121 and the crushing disc 1 211 and the crushing disc 2 215, so that the coffee bean particles are crushed, the coffee powder that meets the pulverization standard will be screened out through the arc-shaped sieve plate 122, and when the pulverizing disc 121 rotates, it will also drive the spring return rod 213 and the crushing block 214 to rotate; When the spring return rod 213 rotates, it will move along the groove 1 212 arc surface, when the spring return rod 213 is separated from the groove 1 212 and contacts the crushing disc 1 211, the spring return rod 213 will be extruded, driving the crushing block 214 to move towards the crushing disc 2 215, so that the spring return rod 213 accumulates the elastic force, and as the pulverizing disc 121 continues to rotate, when the spring return rod 213 moves to the position of the groove 1 212 again, the elastic force of the spring return rod 213 will be released, so that the spring return rod 213 and the crushing block 214 return to the original position; Until the spring return rod 213 again with the broken disc 211 contact, extrusion movement, so the broken block 214 will be in rotation, at the same time, transverse reciprocating movement, broken block 214 transverse reciprocating movement and smaller coffee bean particles contact, through the surface of the convex point, such as Figure 6 The position shown in the middle J, will be on the smaller particles to exert a transverse shear force and friction grinding force, will further tear, broken small particles, accelerate the formation of the required powder particles, improve the uniformity of the crushing particles, effectively prevent the airflow generated by the rotation of the crushing disc 121, will carry smaller particles follow the rotation, difficult to hit smaller particles, easy to cause coffee bean crushing speed is slow, thereby improving the crushing efficiency; Secondly, the coffee beans through the feed pipe 112 into the shell 111 of the crusher, the coffee beans will first enter the connecting cylinder 311, in the crushing disc 121 rotation, will drive the connecting cylinder 311 rotation, in the connecting cylinder 311 of the coffee beans affected by the centrifugal force generated by the rotation of the connecting cylinder 311, will contact with the inner wall of the connecting cylinder 311, follow the connecting cylinder 311 rotation, in the crushing disc 121 rotation, will also change the contact position of the groove two 221 and the sliding frame 222, when the groove two 221 and the sliding frame 222 separate, the sliding frame 222 will be in contact with the crushing disc 121 process, the sliding frame 222 will be extruded, moving away from the motor two 113 direction, the sliding frame 222 will also extrude the spring rod 223, make the spring rod 223 accumulation of resilience; In the process of moving the sliding frame 222, will drive the ring block 312 movement, change the position of the ring block 312, cancel the blocking of the coffee beans in the connecting cylinder 311, at this time, the coffee beans affected by the centrifugal force of the connecting cylinder 311, coffee beans will be thrown out, to the direction of the crushing disc 121 movement with a faster speed, change the impact mode of the coffee beans, the collision force not only comes from the rotation of the crushing disc 121, but also from the coffee beans themselves, the sum of the two forces will make the coffee beans receive greater impact force, more easily broken into smaller particles, effectively prevent multiple coffee beans fall and contact with the crushing disc 121 at the same time, due to the time difference in the process of falling, part of the particles will rebound after impact with the crushing disc 121, impact other particles, will consume part of the impact force, reduce the speed of breaking coffee beans into small particles; Secondly, when the sliding frame 222 moves, the connecting frame 323 will also move, the connecting frame 323 will pull the connecting rod 324 to rotate, and the connecting rod 324 will pull the inclined piston plate 322 to descend, because the speed of the crushing disc 121 rotating is fast, so the speed of the extrusion sliding frame 222 moving is also fast, which will make the inclined piston plate 322 quickly descend, because the outer wall of the inclined piston plate 322 is tightly attached to the inner wall of the connecting frame 321 through the sealing strip, when the inclined piston plate 322 quickly descends, the space at the top of the inclined piston plate 322 will rapidly increase, which will cause the formation of local negative pressure in the connecting frame 321, and the outside atmosphere will quickly flow into the connecting frame 321 through the screen holes of the arc-shaped sieve plate 122 in order to balance the pressure difference; During the gas supplementing process, the gas will push the powder at the top of the connecting frame 321 to fall into the top of the inclined piston plate 322, until the inclined piston plate 322 separates from the connecting frame 321, the coffee powder will flow out through the slope of the inclined piston plate 322, and the outside gas quickly enters the screen holes of the arc-shaped sieve plate 122, which accelerates the discharging speed of the crushed powder, and makes room for the crushing of new materials, effectively preventing the acceleration of the crushing speed of the coffee beans, the screen holes of the arc-shaped sieve plate 122 are small, and the crushed coffee powder is more, which is difficult to quickly discharge, and more powder will be accumulated in the crusher shell 111, which may be subjected to multiple transverse extrusions of the crushing block 214, and is easy to cause part of the powder to be extruded too fine, affecting the uniformity of the crushed particles. Secondly, by quickly crushing the coffee beans into powder and accelerating the discharging speed of the powder, the residence time of the coffee beans in the crusher shell 111 during the process of becoming powder is significantly reduced, the high temperature generated during the crushing of the coffee beans is reduced, the influence on the coffee beans is reduced, and the aroma of the coffee powder is effectively prevented from being volatilized for a long time in the crusher shell 111, and the aroma of the coffee powder is better preserved.
