Description

Technical Field

[0001] The utility model relates to the technical field of twin-screw extruders, in particular to an extrusion and reshaping device for defatted peanuts with an improved structure. Background Art

[0002] Defatted peanuts are made by physical pressing and puffing and reshaping. The peanuts and peanut meal, which is a filler, are placed in a vertical hydraulic oil press and kept at a pressure of 20-25MPa for 1 hour. After the oil is squeezed, the flattened peanuts are puffed and reshaped to obtain whole defatted peanuts. The breakage rate of the peanuts is extremely low and the degree of reshaping is very high. Existing defatted peanut puffing will use an extruder, which generally includes a single-screw extruder, a double-screw extruder, etc. A general double-screw extruder includes a shell, a feeding device, a driving motor, a double-screw system, a heating device, a molding device, a cutting device and a material guiding device. The molding device can shape the defatted peanuts, and the material guiding device can provide guidance for the defatted peanuts after puffing to prevent the defatted peanuts from splashing around after cutting. The material guiding device is generally composed of a guide box, and the defatted peanuts will be discharged from the lower part of the guide box. Heat dissipation holes are opened on the outside of the guide box to facilitate heat dissipation of the molding device and accelerate the cooling of the defatted peanuts. The guide box is fixed to the shell of the double-screw extruder by bolts.

[0003] As in the prior art, the patent with patent announcement number CN114376253A discloses a twin-screw extruder for food processing, including a box, a discharge pipe is arranged on one side outer wall of the box, a feed port is arranged on one side of the top outer wall of the box, and a feed mechanism is arranged on the inner wall of the feed port, a through opening is arranged on one side outer wall of the fixed seat, and a slide plate is slidably connected to the inner wall of the through opening, a second spring is fixedly connected between the top outer wall of the slide plate and the top inner wall of the through opening, two screws are rotatably connected to one side outer wall of the slide plate through a bearing, and one side of the two screws extends to one side of the slide plate, and a pulley is fixedly connected to one side outer wall of the two screws. The above technical scheme prevents the screw from being unable to extrude the food due to the small volume of some food, so that the food remains inside the box, thereby affecting the processing of the food, prevents the food from piling up and causing the inside of the box to be blocked, and can crush larger food.

[0004] Although the twin-screw extruder in the above patent solves the problem that the small volume of food causes food to remain at the bottom of the twin-screw extruder, resulting in poor extrusion effect of the twin screw on the food, which affects food processing, when the existing twin-screw extruder is used, after defatted peanuts are puffed, the staff needs to discharge the excess materials in the twin-screw extruder through the twin screws. During this process, the staff needs to disassemble the forming device. Since the guide box will hinder the disassembly of the forming device, the staff needs to disassemble the guide box first, and then disassemble the forming device before cleaning the twin-screw disc extruder. After the cleaning is completed, the forming device and the guide box need to be reinstalled. The steps are relatively cumbersome, resulting in low cleaning efficiency of the staff, thereby reducing the production efficiency of defatted peanuts. Utility Model Content

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] See also Figure 1-10A defatted peanut puffing and reshaping device with improved structure comprises an puffing machine body 1, a forming device 39 and a material guiding device connected to the puffing machine body 1, wherein the material guiding device comprises a guide box 2, a front plate 3 and a side plate 4, one side of the front plate 3 is rotatably connected to one side of the guide box 2, one side of the side plate 4 is rotatably connected to one side of the front plate 3, the inner sides of the front plate 3 and the side plate 4 are in contact with the inner wall of the guide box 2, a fixing rod 5 is fixedly connected to a side of the side plate 4 away from the front plate 3, one side of the guide box 2 is fixedly connected to two fixing blocks 6, the fixing rod 5 is located between the two fixing blocks 6, a slot 7 is provided in the fixing block 6, a plug rod 9 is slidably connected in the slot 7, a limiting slot 8 corresponding to the position of the plug rod 9 is provided in the fixing rod 5, a discharge box 21 is fixedly connected to the bottom of the guide box 2, a discharge box 21 is provided with a discharge slot 22, and a plurality of heat dissipation holes 10 are provided on the surfaces of the front plate 3 and the side plate 4.

[0029] like Figure 1 As shown, the defatted peanut puffing and reshaping device in the utility model is similar to the existing twin-screw puffing machine structure, such as a food processing twin-screw extrusion puffing machine disclosed in the patent with publication number CN114376253A. The main improvement of the utility model is that the staff can quickly clean the twin-screw puffing machine; in the defatted peanut puffing and reshaping device in the utility model, after the puffing machine body 1 completes one defatted peanut puffing, the staff can first pull out the insertion rod 9 from the limiting groove 8, and then the staff holds the fixing rod 5 and pulls the side plate 4 outward to open the side plate 4. As the side plate 4 is continuously opened, the front plate 3 is also driven by the side plate 4, so that the front side and the right side of the guide box 2 are opened, and the staff can disassemble the forming device 39 to discharge the residual material in the puffing machine body 1; the insertion rod 9 is L-shaped, so as to prevent the insertion rod 9 from falling off, and the staff can pull out the fixing rod 5. The insertion rod 9 can be inserted into the slot 7 by pulling out the insertion rod 9 to prevent the insertion rod 9 from being lost; the front plate 3 and the guide box 2 are rotatably connected by a rotating shaft, hinges, etc., which are not limited here; compared with opening only the front plate 3 or the side plate 4, opening all the front plate 3 and the side plate 4 is more convenient for the staff to use tools such as wrenches to remove the bolts on the forming device 39, preventing the guide box 2 from hindering the staff from using tools such as wrenches, and the front plate 3 is opened for the staff to observe the cleaning status; the guide box 2 and the extruder body 1 are fixedly connected by bolts; the bottom of the insertion rod 9 is a dome setting, which is convenient for the staff to insert the insertion rod 9 into the limit groove 8; it is worth noting that the structure of the extruder body 1 and the forming device 39 in the utility model is similar to the structure of a food processing twin-screw extrusion extruder disclosed in the patent announcement number CN114376253A, so it will not be elaborated on here.

[0030] By arranging the front plate 3 and the side plate 4 on the guide box 2 and utilizing the mutual cooperation between the front plate 3 and the side plate 4, the staff can disassemble the forming device 39 without disassembling the guide box 2. Compared with the original arrangement, the staff saves time in disassembling and assembling the guide box 2, improves the staff's cleaning efficiency of the extruder body 1, and thus improves the production efficiency of the extruder body 1. At the same time, the mutual cooperation between the insertion rod 9 and the fixing rod 5 can conveniently provide fixation for the side plate 4, thereby improving the stability of the side plate 4.

[0031] As a preferred technical solution of the utility model, a rotation groove 11 is provided on the side close to the front plate 3 and the side plate 4, a rotation shaft 12 is fixedly connected in the rotation groove 11, a connecting block 13 is rotatably connected to the outer wall of the rotating shaft 12, and two connecting grooves 14 are provided on the surface of the connecting block 13, and the two connecting grooves 14 are rotatably connected to the rotating shaft 12 on the front plate 3 and the side plate 4 respectively.

[0032] Specifically, the rotation of the front panel 3 and the side panel 4 is achieved by the cooperation of the connecting block 13 and the rotating shaft 12. Compared with directly using the rotating shaft 12 to achieve rotation, the connecting block 13 can enable the front panel 3 and the side panel 4 to achieve a 360-degree all-round rotation, so that the front panel 3 and the side panel 4 can be folded inwardly, thereby reducing the space occupied by the front panel 3 and the side panel 4 after opening, and preventing the front panel 3 and the side panel 4 from hindering the movement of staff.

[0033] As a preferred technical solution of the utility model, two fixing grooves 15 are provided on the top of the guide box 2, a fan 16 is fixedly connected in the fixing grooves 15, a plurality of isolation holes 20 are provided on the bottom surface of the fan 16, a plurality of fixing columns 17 are fixedly connected to the top of the guide box 2, fixing holes 18 corresponding to the positions of the fixing columns 17 are provided at the four corners of the fan 16, and a nut 19 is threadedly connected to the outer wall of the top of the fixing column 17.

[0034] Specifically, when the extruder body 1 is in operation, the fan 16 will suck air into the guide box 2, and the air will be discharged from the heat dissipation holes 10 and the discharge trough 22. The fan 16 can accelerate the air circulation in the guide box 2, increase the heat dissipation capacity of the forming device 39, and also accelerate the cooling of the defatted peanuts, facilitate the rapid falling of the defatted peanuts, and prevent the defatted peanuts from sticking; the isolation hole 20 can prevent the defatted peanuts from being thrown into the fan 16 by the forming device 39 and causing the fan 16 to get stuck, thereby improving the stability of the fan 16 during operation; through the cooperation of the nut 19 and the fixing column 17, the staff can easily disassemble and assemble the fan 16, so as to clean, maintain and replace the fan 16.

[0035] As a preferred technical solution of the utility model, a screening groove 23 is provided on the bottom surface of the discharge trough 22, and a screening plate 24 corresponding to the position of the screening groove 23 is fixedly connected to the bottom surface of the discharge trough 22; a discharge box 25 is fixedly connected to the bottom surface of the discharge box 21, and a discharge trough 26 is provided in the discharge box 25, and the discharge trough 26 is communicated with the screening groove 23.

[0036] Specifically, after the defatted peanuts are separated from the forming device 39, they will fall into the discharge chute 22. At this time, the fine holes on the screening plate 24 will screen the defatted peanuts, and the smaller defatted peanuts or broken grains will be screened and discharged to the discharge chute 26, and the larger defatted peanuts will be discharged from the discharge chute 22, thereby improving the product quality of the defatted peanuts. The smaller defatted peanuts or broken grains discharged can be re-expanded or used to make other products such as peanut butter.

[0037] As a preferred technical solution of the utility model, a plurality of studs 28 are fixedly connected to the bottom surface of the discharge chute 22, and limiting holes 27 corresponding to the positions of the studs 28 are opened at the four corners of the screening plate 24.

A spring 29 is sleeved on the outer wall of the limiting block 30, and both ends of the spring 29 are respectively in contact with the screening plate 24 and the bottom surface of the discharge chute 22.

[0038] Specifically, by utilizing the sliding connection between the screening plate 24 and the limit block 30, when the defatted peanuts fall onto the screening plate 24, under the action of the spring 29, the screening plate 24 will move along the limit block 30 to form a vibration effect. This vibration effect can make the defatted peanuts be screened more thoroughly, further improving the qualified rate and product quality of the defatted peanuts.

[0039] As a preferred technical solution of the present utility model, a lower fixed plate 32 is fixedly connected to the bottom of the inner wall of the guide box 2, and an upper fixed plate 33 is fixedly connected to the top of the inner wall of the guide box 2. The outer walls of the lower fixed plate 32 and the upper fixed plate 33 are in contact with the inner walls of the front plate 3 and the side plate 4.

[0040] Specifically, the lower fixing plate 32 and the upper fixing plate 33 are both magnetic plates, and the front plate 3 and the side plate 4 are made of iron plates such as stainless steel. The front plate 3 and the side plate 4 can be fixed by utilizing the magnetic attraction effect between the front plate 3 and the side plate 4 and the lower fixing plate 32 and the upper fixing plate 33. The lower fixing plate 32 and the upper fixing plate 33 can block the gap between the front plate 3 and the side plate 4 and the guide box 2, so that the connection between the front plate 3 and the side plate 4 and the guide box 2 is stable.

[0041] As a preferred technical solution of the utility model, a cover plate 34 is slidably connected to the top of the guide box 2, and sliding plates 35 are fixedly connected on both sides of the cover plate 34. Two symmetrically arranged connecting plates 36 are fixedly connected to the surface of the guide box 2. A sliding groove 37 corresponding to the position of the sliding plate 35 is opened on one side of the connecting plate 36. The sliding plate 35 is slidably connected to the sliding groove 37, and the two fans 16 are both located in the cover plate 34.

[0042] Specifically, the cover plate 34 can prevent foreign matter from falling into the fan 16, thereby improving the stability of the fan 16 during operation; the cooperation between the sliding plate 35 and the sliding groove 37 allows the staff to easily disassemble and assemble the cover plate 34, thereby disassembling and assembling the fan 16.

[0043] As a preferred technical solution of the present invention, buffer pads 38 are fixedly connected to the four corners of the upper and lower surfaces of the fan 16 , and the surfaces of the buffer pads 38 are in contact with the surfaces of the nut 19 and the guide box 2 .

[0044] Specifically, the buffer pad 38 can reduce the noise generated during the operation of the fan 16, has a shock-proof and buffering effect, protects the fan 16 from vibration damage, can improve the stability and reliability of the fan 16, reduce the failure rate of the fan 16, and thereby reduce the cost of maintenance and replacement; the buffer pad 38 is made of materials such as rubber, polyurethane or spring steel.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
