Description

Technical Field

[0001] This application relates to the field of food ingredient pretreatment, and particularly to a food ingredient pretreatment machine. Background Art

[0002] Food ingredient pretreatment is to preprocess food ingredients to form semi-finished products, reducing the cooking time when consuming food ingredients. With the increasing attention paid to coarse grains by people, some researchers or manufacturers have begun to research and produce instant coarse grain products. The traditional method of making coarse grain products requires self-preparation of coarse grains and prior soaking before cooking, which is time-consuming. Therefore, a pre-cooking process for coarse grains has emerged on the market.

[0003] The pre-cooking process for coarse grains mainly includes the following steps: 1. Removing impurities from coarse grains; 2. Soaking the coarse grains; 3. Drying the soaked coarse grains; 4. Stir-frying the dried coarse grains; 5. Mixing the cooled coarse grains according to weight portions and then packaging.

[0004] In the related art, for the soaking treatment process of coarse grains, generally, a soaking tank is used to soak the coarse grains. When in use, the coarse grains are placed in a soaking barrel. The soaking barrel is provided with a water-permeable structure. Then, the soaking barrel is placed in a soaking tank, and soaking water is added to the soaking tank for soaking. After soaking, the soaking barrel is taken out and transferred to the drying process for drying. During the process of taking out the soaking barrel and transporting it to the drying process, since a large amount of soaking water adheres to the coarse grains, the overall weight of the soaking barrel is increased, which affects the transportation work of the soaking barrel. Moreover, during the transportation of the soaking barrel, the soaking water adhering to the coarse grains will spill onto the processing workshop, affecting the production environment of the processing workshop. Summary of the Invention

[0005] In order to facilitate the cleaning of the soaking water adhering to the coarse grains, this application provides a food ingredient pretreatment machine.

[0006] A food ingredient pretreatment machine provided by this application adopts the following technical solutions:

[0007] A food ingredient pretreatment machine includes a machine body. A feeding pipe is provided on the machine body. An immersion cavity is opened in the machine body. A water inlet pipe and a water outlet pipe communicating with the immersion cavity are provided on the machine body. A turntable is rotatably connected in the immersion cavity. A power component for driving the turntable to rotate is provided on the machine body. A filter water bucket is fixedly connected to the turntable. A feeding pipe and a discharge port are provided on the filter water bucket. A discharge pipe is provided on the turntable. A valve mechanism for communicating the discharge pipe and the discharge port is provided on the discharge pipe.

[0008] By adopting the above technical scheme, when in use, the material is injected into the filter water barrel from the feed pipe, and then the soaking liquid is injected into the soaking chamber to soak the material. After the material is soaked, the water in the soaking chamber is discharged through the outlet pipe, and then the turntable is driven to rotate by the power component, thereby driving the filter water barrel to rotate, and the water adhering to the material is thrown off, and the valve mechanism can be opened to discharge the material in the filter water barrel; the filter water barrel is driven to rotate by the turntable, and the material and water are separated under the action of centrifugal force, which is convenient for the transportation and transfer of the material. At the same time, the soaking water is centrally processed to prevent the soaking water from spilling into the processing workshop and affecting the production environment of the processing workshop.

[0009] Optionally, a vacuum assembly is provided in the water filter barrel, and the vacuum assembly is used to draw air toward the inner wall of the water filter barrel.

[0010] By adopting the above technical solution, after the materials are soaked, more materials will adhere to the inner wall of the water filter barrel. It is difficult to make the materials on the inner wall of the water filter barrel fall off only by gravity, which affects the soaking of other different types of materials. Through the setting of the exhaust component, air can be sucked toward the inner wall of the water filter barrel, so that the external air enters the water filter barrel through the filter holes on the side wall of the water filter barrel, and the materials adhered to the inner wall of the water filter barrel are blown off, preventing the materials from adhering to the inner wall of the water filter barrel.

[0011] Optionally, the vacuum assembly includes a vacuum rod and an air pump, the vacuum rod is arranged inside the water filter barrel along the height direction of the water filter barrel, the vacuum rod is hollow, a plurality of stirring rods are fixed on the outer wall of the vacuum rod, the stirring rod is provided with an air passage for connecting the vacuum rod and the inside of the water filter barrel, and the air pump is used to connect the vacuum rod.

[0012] By adopting the above technical solution, when pumping air, turn on the air pump, the gas enters the pumping rod from the air channel on the stirring rod, and is discharged through the air outlet of the air pump. The pumping assembly has a simple structure and is easy to operate. The multiple stirring rods arranged on the pumping rod can pump air from the water filter barrel from all sides, thereby improving the cleaning efficiency of the inner wall of the water filter barrel.

[0013] Optionally, the suction rod is rotatably connected in the water filter barrel, and the water filter barrel is provided with a motor for driving the suction rod to rotate.

[0014] By adopting the above technical solution, when soaking the material, the vacuum rod is driven to rotate by the motor, thereby driving the stirring rod to rotate, thereby improving the soaking effect of the material; in addition, since the vacuum rod can rotate, in the process of driving the stirring rod to rotate, the inner wall of the water filter barrel can be vacuumed and cleaned along the circumference of the water filter barrel.

[0015] Optionally, the valve mechanism includes a sleeve and a movable rod. The sleeve is fixed inside the discharge pipe. The movable rod is arranged inside the sleeve and can move along the height direction of the filter water bucket. A cover plate is fixedly connected to the part of the movable rod outside the sleeve. The cover plate moves with the movable rod to open and close the discharge port. A first driving member for driving the movable rod to move is provided on the turntable.

[0016] By adopting the above technical solution, when discharging the material from the filter water bucket, the first driving member drives the movable rod to move vertically upward, thereby driving the cover plate to move. After the cover plate disengages from the discharge pipe, the discharge pipe is opened, and thus the material can be discharged from the discharge pipe. The setting of this valve mechanism does not affect the rotation of the stirring rod.

[0017] Optionally, the first driving member adopts an air pump. The air pump is communicated with the sleeve. A communication groove is formed in the movable rod. A piston is arranged inside the sleeve. The movable rod is fixedly connected to the piston. An air hole for communicating the communication groove and the sleeve is provided on the piston. One end of the movable rod away from the piston is slidably inserted into the air extraction rod so that the sleeve is communicated with the air extraction rod through the communication groove. A one-way valve structure is arranged in the communication groove, and the one-way valve structure is used to limit the gas from entering the air extraction rod from the sleeve.

[0018] By adopting the above technical solution, during air extraction, due to the existence of the cover plate, the movable rod cannot move downward. Thus, the gas enters the communication groove through the stirring rod and then enters the sleeve through the communication groove, and then is discharged through the air pump. When it is necessary to open the valve mechanism to move the cover plate upward, the air pump injects gas into the sleeve. Due to the existence of the one-way valve mechanism, the gas cannot enter the filter water bucket through the communication groove. At this time, due to the air pressure, the piston will be pushed upward, thereby driving the movable rod to move upward, and then driving the cover plate to move upward. The upward movement of the movable rod and the air extraction work of the filter water bucket are realized by one air pump, reducing the complexity of the device. At the same time, it can support the stirring rod and make the stirring rod operate stably during the stirring work.

[0019] Optionally, an immersion box is provided on the turntable. The filter water bucket is arranged inside the immersion box. Water inlet holes are formed in the side wall of the immersion box. A collar for sleeving on the filter water bucket is arranged inside the immersion box. The collar is hollow. A plurality of communication holes communicating with the collar are formed on the inner wall of the collar. A hose communicating with the collar is fixedly connected to the outer wall of the collar. One end of the hose away from the collar is used to communicate with the water inlet hole. The collar can move along the height direction of the filter water bucket. A second driving member for driving the collar to move is provided on the immersion box. A drain pipe is arranged on the bottom surface of the immersion box. A valve for opening and closing the drain pipe is provided on the drain pipe. The end of the feed pipe away from the filter water bucket passes through the upper surface of the immersion box and abuts against the inner top surface of the machine body. The turntable rotates to align the feed pipe with the feeding pipe.

[0020] By adopting the above technical solution, since the water filtering bucket needs to filter water quickly, the four sides of the water filtering bucket are all connected to the outside world. When the water filtering bucket is evacuated, it is impossible to concentrate on evacuating a certain height position on the inner wall of the water filtering bucket, resulting in a poor cleaning effect on the materials adhering to the inner wall of the water filtering bucket. By providing an immersion box and placing the water filtering bucket in the immersion box, the water filtering bucket and the immersion cavity are isolated, and a vertically movable collar is provided on the water filtering bucket. Thus, when the water filtering bucket is evacuated, the gas in the immersion cavity can only enter the hose through the through hole, and then enter the water filtering bucket through the communication hole, so that a targeted evacuation can be carried out at a certain height of the water filtering bucket. By driving the collar to move vertically by the second driving member, a targeted evacuation can be carried out on the water filtering bucket successively along the height direction of the water filtering bucket, improving the cleaning effect of the materials adhering to the inner wall of the water filtering bucket.

[0021] In summary, the present application includes the following beneficial technical effects:

[0022] 1. In the present application, the turntable drives the water filtering bucket to rotate. After the materials are soaked, the water in the water filtering bucket can be thrown off by centrifugal force to separate the materials from the water, facilitating the subsequent transportation and transfer of the materials;

[0023] 2. In the present application, through the setting of the air extraction assembly, it is convenient to clean the materials adhering to the inner wall of the water filtering bucket, preventing the materials adhering to the inner wall of the water filtering bucket from mixing with the subsequent materials to be processed.

[0030] The following is a further detailed description of the present application in conjunction with the attached Figures 1-4 figures.

[0031] The present application discloses a food ingredient pretreatment machine.

[0032] Referring to Figure 1 and Figure 2 , a food ingredient pretreatment machine includes a processing mechanism and a transportation mechanism. The processing mechanism includes a body 1. In this embodiment, the body 1 is cylindrical. An soaking chamber 2 is opened inside the body 1. A turntable 3 is coaxially arranged inside the soaking chamber 2. An soaking box 4 is fixedly connected to the turntable 3. The soaking box 4 is annular, and the soaking box 4 and the body 1 are coaxially arranged. A plurality of filter water buckets 5 are fixedly connected inside the soaking box 4. In this embodiment, three filter water buckets 5 are provided, and the three filter water buckets 5 are equidistantly arranged along the circumferential direction of the turntable 3.

[0033] Referring to Figure 2 and Figure 3 , in order to facilitate adding materials to the filter water bucket 5, a feed pipe 6 is communicated with the upper surface of the filter water bucket 5. The end of the feed pipe 6 away from the filter water bucket 5 passes through the upper surface of the soaking box 4. A loading pipe 7 is fixedly connected to the body 1. The loading pipe 7 is used to be aligned and communicated with the feed pipe 6.

[0034] In this embodiment, due to the setting of a plurality of filter water buckets 5, in order to facilitate the alignment and communication of one loading pipe 7 and the feed pipes 6 of the plurality of filter water buckets 5, the turntable 3 is rotatably connected in the soaking chamber 2. The rotation axis of the turntable 3 is coaxial with the body 1. A power component for driving the turntable 3 to rotate is provided on the bottom surface of the soaking chamber 2; the turntable 3 rotates to align and communicate the feed pipes 6 on the plurality of filter water buckets 5 with the loading pipe 7 in sequence.

[0035] The power component includes a motor 2 8. The motor 2 8 is fixed on the bottom surface of the soaking chamber 2. The output shaft of the motor 2 8 is coaxially fixedly connected with a rotating rod 9. The end of the rotating rod 9 away from the motor 2 8 is coaxially fixedly connected with the lower surface of the turntable 3. In this embodiment, the motor 2 8 is an underwater working motor.

[0036] Reference Figure 2 and Figure 4 To facilitate adding water into the soaking box 4 for soaking the material, a plurality of water inlet holes 10 are formed in the inner wall of the soaking box 4. In this embodiment, the number of water inlet holes 10 is the same as the number of filter water buckets 5; a water inlet pipe 11 is fixedly connected to the top surface of the machine body 1, and the water inlet pipe 11 communicates with the part of the soaking cavity 2 surrounded by the inner wall of the soaking box 4.

[0037] In addition, after the material soaking is completed, to facilitate the discharge of the water in the soaking box 4, a drain pipe 12 is fixedly connected to the bottom surface of the soaking box 4, and the lower end of the drain pipe 12 extends into the soaking cavity 2 below the turntable 3. An electromagnetic valve is installed on the drain pipe 12; in addition, to discharge the water in the soaking cavity 2, a water outlet pipe 13 is fixedly connected to the bottom surface of the machine body 1, the water outlet pipe 13 communicates with the soaking cavity 2, and a control valve is installed on the water outlet pipe 13.

[0038] During use, first rotate the turntable 3 to align the feeding pipe 6 on the feeding pipe 7 and the filter water bucket 5, then convey the material into the filter water bucket 5, and then inject water into the soaking cavity 2 through the water inlet pipe 11. The water enters the soaking box 4 through the water inlet holes 10 to soak the material in the filter water bucket 5. After the material soaking is completed, drive the turntable 3 to rotate by the second motor 8, thereby driving the filter water bucket 5 to rotate, and the water is thrown into the soaking box 4 by the centrifugal force, and then discharged through the drain pipe 12.

[0039] After the water in the soaking box 4 is preliminarily treated, it is necessary to discharge the material in the filter water bucket 5. To facilitate discharging the material in the filter water bucket 5, a discharge port 14 is formed in the filter water bucket 5, and a discharge pipe 15 is fixedly connected to the turntable 3. The discharge pipe 15 is vertically arranged, and the lower end of the discharge pipe 15 passes through the inner bottom surface of the machine body 1 and extends to the outside of the machine body 1. A valve mechanism for communicating the discharge port 14 and the discharge pipe 15 is provided on the discharge pipe 15.

[0040] The valve mechanism includes a sleeve 16 and a movable rod 17. A bearing rod 18 is fixedly connected in the discharge pipe 15. The sleeve 16 is vertically arranged, and the lower end of the sleeve 16 is fixed on the bearing rod 18. A piston 19 capable of moving along the height direction of the sleeve 16 is arranged in the sleeve 16, and the outer wall of the piston 19 and the inner wall of the sleeve 16 are hermetically arranged. The lower end of the movable rod 17 is fixedly arranged on the piston 19. A cover plate 20 is fixedly connected to the part of the movable rod 17 extending out of the sleeve 16. The cover plate 20 moves vertically with the movable rod 17 to communicate the discharge port 14 and the discharge pipe 15; a first driving member for driving the movable rod 17 to move is provided on the turntable 3.

[0041] In another embodiment, the valve mechanism can also adopt an electromagnetic valve.

[0042] In this embodiment, the first driving member adopts an air pump 21. The bearing rod 18 is hollow. The air pump 21 is fixed on the outer wall of the discharge pipe 15. The air pump 21 is connected to the bearing rod 18 through an air pipe, and the bearing rod 18 is connected to the sleeve 16.

[0043] When the driving cover plate 20 moves vertically, the air pump 21 is turned on to inject air into the sleeve 16. Under the action of air pressure, the movable rod 17 is driven to move, and then the cover plate 20 is driven to move.

[0044] In another embodiment, the first driving member can also adopt a hydraulic pump.

[0045] At the same time, in order to enable the material to be discharged smoothly, the cover plate 20 has a spherical convex surface.

[0046] In this embodiment, since the material may adhere to the inner wall of the filter water bucket 5 after being wetted, in order to clean the material adhering to the inner wall of the filter water bucket 5, an air extraction assembly is provided on the filter water bucket 5, and the air extraction assembly is used to extract air towards the inner wall of the filter water bucket 5.

[0047] The air extraction assembly includes an air extraction rod 23. The air extraction rod 23 is vertically arranged and coaxially installed in the filter water bucket 5. A plurality of stirring rods 24 are fixedly connected to the outer wall of the air extraction rod 23. Air channels 25 for communicating the air extraction rod 23 and the interior of the filter water bucket 5 are formed on the stirring rods 24. The upper end of the movable rod 17 is inserted into the air extraction rod 23. A communication groove 26 is formed in the movable rod 17, and the communication groove 26 penetrates through both ends of the movable rod 17. An air hole 27 for communicating the communication groove 26 and the sleeve 16 is provided on the piston 19.

[0048] When extracting air from the interior of the filter water bucket 5, the air pump 21 is turned on. Under the action of air pressure, the gas in the soaking box 4 enters the interior of the filter water bucket 5 through the filter holes on the filter water bucket 5, and then enters the communication groove 26 through the air channels 25 on the stirring rods 24. The gas then enters the sleeve 16 through the communication groove 26 and is discharged through the air pump 21. Thus, through the impact of the air flow, the material adhering to the inner wall of the filter water bucket 5 can be cleaned off.

[0049] In addition, in order to position the piston 19, a positioning block 37 is fixedly connected to the inner wall of the sleeve 16, and the positioning is used to abut against the lower surface of the piston 19.

[0050] In this embodiment, since the air pump 21 needs to inflate the sleeve 16 to move the cover plate 20 upward so as to discharge the material in the filter water bucket 5, and at the same time the air pump 21 needs to extract air from the interior of the filter water bucket 5 through the communication groove 26. Due to the setting of the communication groove 26, when the air pump 21 drives the movable rod 17 to move upward, the gas will be discharged through the communication groove 26, thus failing to achieve the purpose of moving the movable rod 17 upward. Therefore, a one-way valve structure 28 is installed in the communication groove 26. The one-way valve structure 28 is a well-known technology and will not be elaborated in this application.

[0051] In addition, in order to reset the movable rod 17, a spring 22 is fixedly connected inside the air extraction rod 23. The length direction of the spring 22 is arranged along the vertical direction, and the lower end of the spring 22 abuts against the movable rod 17.

[0052] Referring to Figure 3 and Figure 4 , in actual production, since the volume of the filter water bucket 5 is large, when air is extracted from the filter water bucket 5 to clean the materials adhered to the filter water bucket 5, the air flow cannot be concentrated, resulting in an unsatisfactory cleaning effect. To improve the cleaning effect, a collar 29 is sleeved on the filter water bucket 5. The collar 29 is located between the filter water bucket 5 and the inner wall of the soaking box 4. The outer wall of the collar 29 and the inner wall of the soaking box 4 are hermetically arranged, and the inner wall of the collar 29 and the outer wall of the filter water bucket 5 are hermetically arranged; the collar 29 is hollow, and a plurality of communication holes 30 are formed in the inner wall of the collar 29 along its circumferential direction. A communication pipe 31 is fixedly connected between adjacent collars 29, and the communication pipe 31 connects adjacent collars 29. A hose 32 is fixedly connected and communicated with the inner wall of the water inlet hole 10. The end of the hose 32 away from the water inlet hole 10 is communicated with the communication pipe 31. The hose 32 is made of corrugated pipe; the collar 29 can move vertically, and a second driving member for driving the collar 29 to move vertically is provided on the soaking box 4.

[0053] The second driving member adopts a cylinder 33. The cylinder 33 is arranged vertically. The fixed end of the cylinder 33 is fixedly connected to the inner top surface of the soaking box 4, and the telescopic end of the cylinder 33 is fixedly connected to the upper surface of the collar 29.

[0054] In another embodiment, the second driving member can also be a screw drive member.

[0055] In this embodiment, in order to improve the sealing effect of the soaking box 4 and prevent air from entering through the feed pipe 6 of the filter water bucket 5, the upper surface of the soaking box 4 abuts against the inner top surface of the machine body 1.

[0056] In this embodiment, in order to improve the soaking effect of the materials, the air extraction rod 23 is rotatably connected to the top surface of the filter water bucket 5. The rotation axis of the air extraction rod 23 is arranged along the vertical direction. A first motor 34 for driving the air extraction rod 23 to rotate is fixedly connected to the upper surface of the filter water bucket 5.

[0057] The transportation mechanism includes a conveyor belt 36. A receiving box 35 is placed on the conveyor belt 36. The receiving box 35 is moved to below the discharge pipe 15 through the conveyor belt 36. By opening the valve mechanism, the materials in the filter water bucket 5 can fall into the receiving box 35.

[0058] The implementation principle of a food ingredient pre-processor disclosed in this application is as follows: When in use, first rotate the turntable 3 to align the feeding pipe 7 on it with the feeding pipe 6 on the filter water bucket 5. Then, add materials to the filter water bucket 5 through the feeding pipe 7. After the materials are added, add water to the soaking chamber 2 through the water inlet pipe 11. The water enters the soaking box 4 through the water inlet holes 10 to soak the materials. After soaking, open the water outlet pipe 13 and the drain pipe 12 to drain the water in the soaking chamber 2 and the soaking box 4. Then, drive the turntable 3 to rotate by the second motor 8 to shake off the water adhered to the materials in the filter water bucket 5. After the water adhered to the materials is preliminarily processed, turn on the air pump 21 to inflate the sleeve 16. Under the action of the one-way valve mechanism, the air flow pushes the movable rod 17 to move upward, thereby driving the cover plate 20 to move upward to open the discharge port 14. The materials in the filter water bucket 5 fall into the receiving box 35 through the discharge pipe 15;

[0059] After the materials are preliminarily discharged, turn on the air pump 21 to evacuate the sleeve 16. At the same time, turn on the cylinder 33 to make the collar 29 move intermittently. The gas enters the collar 29 through the water inlet holes 10 and the hose 32, and then enters the filter water bucket 5 through the communication holes 30 on the collar 29. The air cylinder in the filter water bucket 5 then enters the air extraction rod 23 through the air duct 25 on the stirring rod 24, and then enters the air cylinder through the communication groove 26 and is extracted under the action of the air pump 21. During the process of the gas entering the filter water bucket 5 through the collar 29, under the action of the air flow, the materials adhered to the filter water bucket 5 will be blown off. At the same time, since the collar 29 moves intermittently downward under the action of the cylinder 33, it is possible to perform targeted blowing treatment on each height part of the filter water bucket 5 in the vertical direction to improve the cleaning effect.

[0060] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
