Description

Technical Field

[0001] This utility model relates to a production line, and more particularly to a production line for removing the green coating from hemp seed cake. Background Technology

[0002] Hemp seed powder cake is a byproduct of pressing hemp seeds for oil. This powder cake undergoes further processing, including crushing and grinding, to ultimately become hemp seed protein powder. However, because the white hemp kernels are covered by a green outer layer, this green layer mixes completely with the kernels in the powder cake after oil extraction. This powder cake requires multiple crushing and grinding processes to break down the green outer layer into extremely fine particles, in order to meet the customer's desired appearance and color for the hemp seed protein powder. While this multi-stage crushing and grinding method achieves the customer's requirements, it increases equipment energy consumption and reduces product output within the same timeframe. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a production line for removing the green skin of hemp seed cake that can reduce the number of crushing and grinding times, reduce the energy consumption of equipment, and increase the yield of hemp seed protein powder during the processing of hemp seed protein powder.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A production line for removing the green coating from hemp seed cake includes a feeding hopper, a vibrating feeder, a Z-shaped elevator, and a vibrating equalizing screen arranged in sequence. The vibrating feeder is located between the outlet at the lower end of the feeding hopper and the Z-shaped elevator. At the outlet end of the Z-shaped elevator, a buffer hopper and a dispersing machine are installed vertically via a support frame. The discharge port at the lower end of the buffer hopper corresponds to the inlet at the upper end of the dispersing machine, and the discharge port at the lower end of the dispersing machine corresponds to and communicates with the inlet at the upper end of the vibrating equalizing screen. This is used to disperse the material lifted by the Z-shaped elevator and then transmit it to the vibrating equalizing screen, which is used to fully disperse the material.

[0006] A skin-suction chamber is provided at the discharge end of the vibrating uniform screen. The lower end of the skin-suction chamber is provided with a discharge port, and the upper end of the skin-suction chamber is provided with a suction port. A skin-suction sedimentation machine is provided on one side of the skin-suction chamber. The inlet of the skin-suction sedimentation machine is connected to the suction port, which is used to suck away and collect the green skin in the hemp seed cake material.

[0007] As a further preferred embodiment, the buffer hopper consists of two cone-shaped hoppers, and a gate valve is installed at the discharge port at the lower end of the buffer hopper to control the amount of material discharged downwards.

[0008] As a further preferred option, there are two dispersers, each corresponding to one of the buffer hoppers above.

[0009] As a further preferred embodiment, the vibrating uniform screen adopts a vibrating feeder structure, which has two layers of vibrating plates arranged vertically, and a top cover plate is detachably fixed above the two layers of vibrating plates. The feed inlet is located on the top cover plate to prevent the generated smoke and dust from flying into the production environment.

[0010] As a further preferred embodiment, the skin suction chambers are two arranged in parallel front to back, namely the first skin suction chamber and the second skin suction chamber. Each of the two skin suction chambers has a feed inlet on one side of the vibrating uniform screen. The upper vibrating plate of the vibrating uniform screen is inserted into the feed inlet of the first skin suction chamber, and the discharge port at the lower end of the first skin suction chamber is located above the lower vibrating plate of the vibrating uniform screen. The lower vibrating plate is inserted into the feed inlet of the second skin suction chamber.

[0011] As a further preferred embodiment, the skin suction sedimentation machine consists of two units, with the feed inlet connected to the air intake of each of the two skin suction chambers via flexible hoses. The skin suction sedimentation machine adopts a cyclone separator structure.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This application uses a feeding hopper, a vibrating feeder, a Z-shaped elevator, and a vibrating uniform screen arranged in sequence. A skin-suction air chamber is provided at the discharge end of the vibrating uniform screen, and a skin-suction settling machine is provided on one side of the skin-suction air chamber. The inlet of the skin-suction settling machine is connected to the air intake at the upper end of the skin-suction air chamber. This can remove the green outer layer of hemp seed cake before the crushing and grinding process. It has a large processing capacity and reduces production energy consumption compared with the multiple grinding schemes of the prior art. It can reduce the number of crushing and grinding times in the processing of hemp seed protein powder, reduce the energy consumption of the equipment, and increase the yield of hemp seed protein powder.

[0014] 2. The vibrating material equalization screen can evenly disperse the material after it has been broken up by the dispersing machine. The two suction chambers and two suction settling machines arranged at the front and back can remove the dispersed material twice, resulting in a good removal effect. The raw materials after removal can then be used to produce hemp seed protein powder products, which can better ensure the appearance and color of the products and improve customer satisfaction.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] like Figure 1-6 As shown, the present invention relates to a production line for removing the green coating from hemp seed cake, comprising a feeding hopper 1, a vibrating feeder 2, a Z-type elevator 3, and a vibrating equalizing screen 7 arranged in sequence. The feeding hopper 1 is supported on the ground by a bracket 12. The vibrating feeder 2 is fixed on the bracket 12 and located between the outlet at the lower end of the feeding hopper 1 and the inlet of the Z-type elevator 3; it is used to transfer the hemp seed cake material fed into the feeding hopper 1 to the Z-type elevator 3.

[0024] At one end of the outlet of the Z-type elevator 3, a buffer hopper 4 and a dispersant 5 are fixedly installed by a support frame 6. The discharge port at the lower end of the buffer hopper 4 corresponds to the feed port at the upper end of the dispersant 5. The discharge port at the lower end of the dispersant 5 corresponds to and communicates with the feed port at the upper end of the vibrating uniform screen 7. This is used to disperse the material lifted by the Z-type elevator 3 and then transmit it to the vibrating uniform screen 7. The vibrating uniform screen 7 is used to fully disperse the material.

[0025] The buffer hoppers 4 consist of two conical hoppers, each with a gate valve 13 installed at its lower outlet to control the amount of material discharged downwards. The Z-type elevator 3 has two outlets 301 arranged in an inverted V-shape, each corresponding to the upper port of one of the two buffer hoppers 4. The dispersing machines 5 consist of two units, each corresponding to one of the upper buffer hoppers 4.

[0026] The dispersant 5 adopts the centrifugal dehulling machine structure disclosed in CN101298059A. The material is dispersed by the rotation of the impeller inside the dispersant 5. The dispersed material splashes onto the outer cylinder wall of the dispersant 5 and falls down, and is discharged from the discharge port through the cone-shaped structure at the bottom of the outer cylinder wall.

[0027] The vibrating equalizing screen 7 adopts a vibrating feeder structure, which has two layers of vibrating plates 701 arranged vertically. A top cover plate 702 is detachably fixed to the frame above the two layers of vibrating plates 701 by bolts. The vibrating equalizing screen 7 has two feed inlets, each located on a corresponding top cover plate 702, and these inlets correspond one-to-one with the discharge outlets at the lower ends of the two dispersing machines 5 to prevent dust generated from entering the production environment. The top cover plate 702 consists of two pieces for easy disassembly.

[0028] A skin-suction chamber is provided at the discharge end of the vibrating equalizing screen 7. The lower end of the skin-suction chamber is provided with a discharge port, and the upper end of the skin-suction chamber is provided with a suction port. A skin-suction settling machine 10 is provided on one side of the skin-suction chamber. The inlet of the skin-suction settling machine 10 is connected to the suction port and is used to suck away and collect the green skin in the hemp seed cake material.

[0029] The suction chambers consist of two parallel structures, designated as the first suction chamber 8 and the second suction chamber 9. Each suction chamber has an inlet on one side corresponding to the vibrating equalizing screen 7. The upper vibrating plate 701 of the vibrating equalizing screen 7 is inserted into the inlet 801 of the first suction chamber 8. The outlet 802 at the lower end of the first suction chamber 8 is an open structure located above the lower vibrating plate 701 of the vibrating equalizing screen 7. The lower vibrating plate 701 is inserted into the inlet 901 of the second suction chamber 9. The outlet 902 of the second suction chamber 9 is arranged inclined downwards and outwards. The inlet, outlet, and suction port of each suction chamber are connected to its internal air chamber, allowing the green clothing to be sucked away through the suction port and the hemp seed powder to be discharged through the outlet.

[0030] An adjustable upper plate 17 and an adjustable lower plate 15 are respectively installed on one side of the air chamber within the frame 14 of the two suction chambers with a clearance fit. The inner sides of the adjustable upper plate 17 and the adjustable lower plate 15 are hinged by a hinge 21 and sealed by a connecting rubber 16. A rotatable adjusting rod 18 is provided on the outer side of the upper end of the adjustable upper plate 17 on the frame 14 of the suction chamber, and a locking disc 22 is provided at one end of the adjusting rod 18. The locking disc 22 has symmetrical arc-shaped elongated holes and is fixed to a fixed disc fixed on the outer side of the frame 14 by bolts passing through the arc-shaped elongated holes. The fixed disc is sleeved on the adjusting rod 18 for locking the adjusted adjusting rod 18. The adjustable upper plate 17 is fixedly connected to the adjusting rod 18 via multiple connecting plates 19, allowing adjustment of the angle of the adjustable upper plate 17, thereby adjusting the wind speed at the corresponding location in the air chamber. Adjusting screws 20 are symmetrically installed on the frame 14 of the suction chamber, located on the lower outer side of the adjustable lower plate 15, via nuts. The inner end of the adjusting screw 20 is fixed to the adjustable lower plate 15, allowing adjustment of the position of the adjustable lower plate 15, thereby adjusting the wind speed at the corresponding location in the air chamber. Two transparent glass plates 23 are symmetrically installed on the adjustable lower plate 15 to facilitate observation of the suction operation inside the suction chamber.

[0031] The skin suction sedimentation machine 10 consists of two units, and the feed inlet is connected to the air intake of the two skin suction chambers respectively through a hose 11. The skin suction sedimentation machine 10 adopts a cyclone separator structure.

[0032] The operating steps are as follows:

[0033] 1. Start the blowers of the vibrating feeder, Z-type elevator 3, vibrating equalization screen 7 and skin suction settling machine 10, and manually feed the hemp seed cake raw material into the feeding hopper 1. The material is transferred to the Z-type elevator 3 by adjusting the vibrating feeder. The amount of material fed into the Z-type elevator 3 is controlled by adjusting the vibration frequency of the vibrating feeder. The hemp seed cake raw material is lifted by the Z-type elevator 3 and fed into the buffer hopper 4.

[0034] 2. When there is a certain amount of material in the buffer hopper 4, open the slide valve 13 at the lower end of the buffer hopper 4; by adjusting the slide valve 13, ensure that the input of the vibrating feeder is consistent with the output of the buffer hopper 4.

[0035] 3. When the slide valve 13 of the buffer hopper 4 is opened, the material enters the disperser 5 for dispersing. The dispersed material enters the vibrating equalizing screen 7. Through the vibration and dispersing effect of the vibrating equalizing screen 7, the green outer skin and white kernel powder in the dispersed hemp seed cake can be fully dispersed. The upper cover plate 702 can effectively prevent the generated smoke and dust from flying into the production environment.

[0036] 4. After the hemp seed powder settling machine 10 is started, a negative pressure is formed in the suction chamber through the hose. The dispersed hemp seed powder raw material is discharged from the upper vibrating plate of the vibrating equalizing screen 7 and enters the first suction chamber 8. A portion of the green outer layer is sucked away by the negative pressure in the first suction chamber 8. The hemp seed powder raw material after suction falls onto the lower vibrating plate of the vibrating equalizing screen 7. After exiting the lower vibrating plate, it enters the second suction chamber 9 to remove the green outer layer again. The material after the green outer layer is removed is discharged through the outlet of the second suction chamber 9 and collected manually.

[0037] 5. The green outer garments removed from the two suction chambers are sucked into the corresponding suction settling machine 10 through hoses, and then collected manually after settling.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
