Description

Technical Field

[0001] This invention belongs to the field of puffed food processing, and specifically relates to a puffed food production line. Background Technology

[0002] Puffed foods are snack foods made primarily from grains, potatoes, or beans, processed using puffing techniques such as baking, frying, microwaving, or extrusion. These foods are characterized by their significantly increased volume, crisp texture, fragrant aroma, and diverse flavors. Common examples include rice crackers, potato chips, shrimp chips, popcorn, and rice crackers. While some automated processing equipment can replace manual labor in the traditional processing of puffed foods, existing production lines still require manual operation for feeding and unloading materials into and out of each machine, as well as manual handling of processed products between machines. This results in low automation, high labor requirements, high labor intensity, and inconvenience for continuous production. Especially in the production of various types or flavors, human fatigue can easily lead to misplacement or dangerous operations, compromising production efficiency and quality, causing inconvenience.

[0022] (III) Beneficial Effects

[0023] One of the above technical solutions has the following advantages or beneficial effects:

[0024] To address the shortcomings of existing production lines where manual operation is still required for feeding and unloading of materials into and out of various equipment, and for manually moving processed products between different machines, resulting in low automation, high labor intensity, and inconvenience for continuous production, especially in the production of multiple types or flavors of products, manual labor can easily lead to misplacement or dangerous operations due to fatigue, compromising production efficiency and quality. This leads to a solution where a combination of elevators and feeding devices automates the feeding of multiple drying machines, storage tanks, and packaging machines. This is combined with frying equipment equipped with automatic feeding hoppers. The discharge from the drying machines is conveyed via a conveyor belt and elevator to a vibrating screen. The discharge from the vibrating screen is then lifted by the elevator to the feeding device for automatic selection of different storage tanks. The process involves feeding materials into storage tanks, which can then weigh and discharge different types or flavors of materials according to production needs. The discharged materials are automatically conveyed to metering equipment via conveyor belt and elevator, and then pass through a rotating screen for secondary sieving. The discharged materials are then lifted to the frying hopper for automatic weighing and frying. After frying, the finished products are filtered and cooled before being lifted to the feeding equipment of the packaging machine for selective packaging. This allows the production line to achieve fully automated production of different types and flavors, requiring only a small number of personnel to add initial materials at fixed locations and monitor and control the equipment at the control center. This significantly reduces the number of workers and labor intensity, facilitates continuous production, and better avoids human error, dangerous operations, and other situations, thereby improving production efficiency and quality.

[0057] Implementation Plan: During production, only manual addition of initial raw materials is required at the eighth elevator 4c in the drying area 4. The eighth elevator 4c will then transport the raw materials to the corresponding fourth feeding device 4b. At this time, the linear motor 1d7 of the fourth feeding device 4b will drive the feeding hopper 1d5 to the discharge port of the eighth elevator 4c to receive the discharged material. After receiving the discharged material, the feeding hopper 1d5 is driven by the linear motor 1d7 to the corresponding drying device 4f area to feed the material to the fifth feeding device. The fifth feeding device 4e then feeds the material into the drying device 4f. During feeding, the first pump rod 1d4 drives the first baffle 1d10 to move and open the bottom slot of the feeding hopper 1d5 for feeding. The fed material passes through the drying feed hopper 4f8 and enters the extension ring 4f9, where it is received by the induction plate 4f20 and the fifth baffle 4f21. The induction plate 4f20 senses the feeding through the second gravity sensor 4f19 and feeds back to the control center 5. The control center 5 records the data according to the set program. The weight of the feed is controlled, and the screen cylinder 4f12 is rotated to the top of the inlet / outlet 4f11. The photoelectric sensor 4f10 mounted on the extension ring 4f9 and the reflector 4f23 on the cover plate 4f24 facilitate positioning. When the screen cylinder 4f12 is rotated to the top of the inlet / outlet 4f11, the drive motor 4f17 rotates the gear 4f18, which drives the cover plate 4f24 to open the inlet / outlet 4f11 through the tooth surface 4f26 of the drive groove 4f25. Then the fifth pump rod 4f22... The sensor plate 4f20 and the fifth baffle 4f21 can open the bottom slot of the extension ring 4f9, allowing the drying feed hopper 4f8 and the extension ring 4f9 to enter the screen cylinder 4f12 for drying. Then the bottom slot of the extension ring 4f9 and the inlet / outlet 4f11 close again. During drying, the hot air pipe 4f28 provides heat to the inside of the equipment, and the drying motor 4f27 drives the screen cylinder 4f12 to rotate for drying, making the drying more uniform and realizing automatic feeding and drying of different drying equipment 4f during production.

[0058] After the drying process is completed, the fourth pump rod 4f2 drives the fourth baffle 4f16 to open the discharge chute 4f13, and the discharge port 4f11 of the screen cylinder 4f12 rotates to the bottom, opening the inlet and outlet ports 4f11 for discharge. The discharge from the screen cylinder 4f12 will slide down to the fifth conveyor belt 4g through the guide plate 4f3. The fifth conveyor belt 4g will then transport the material to the ninth elevator 4i. The ninth elevator 4i will lift the material into the vibrating screen 4a for the first screening to ensure product quality.

[0059] The material retained by the vibrating screen 4a is lifted by the sixth elevator 3c to the second feeding device 3d. The second feeding device 3d then feeds the material into the third feeding device 3e in different storage tank 3b areas. The third feeding device 3e moves to the corresponding third conveyor belt 3g according to the type and flavor of the material. The third conveyor belt 3g then conveys the material to the corresponding seventh elevator 3h through different conveying directions. The seventh elevator 3h then lifts the material into the corresponding storage tank 3b for heat preservation and storage. During storage, the material... Temperature and humidity sensors 3b4, located on the upper, middle, and lower sides of the storage tank 3b, can comprehensively monitor the temperature and humidity inside the storage tank 3b5. The first partition connector 3b2 can adjust the insulation temperature inside the storage tank 3b5. The vent connector 3b1 can reduce the air pressure and release moisture inside the storage tank 3b5, ensuring the safety and stability of material storage. It also facilitates the selection of different types and flavors for production needs, and allows for the automatic storage and use of materials when there are production needs or when production needs are temporarily changed.

[0060] When there is a production demand for material discharge, the second pump rod 3b12 at the bottom of the storage tank 3b will drive the second baffle 3b13 to open the discharge connector 3b14. After some material enters the discharge hopper 3b6 and weighing connector 3b9, the discharge connector 3b14 will be closed, so that the weighing connector 3b9 can weigh the material discharged through the first gravity sensor 3b11 connected to the inner ring 3b10. Then, the discharge hopper 3b6 can be opened by the third pump rod 3b18 to open the third baffle 3b19, so that the material falls onto the second conveyor belt 3a, realizing automatic weighing and discharge of the storage tank 3b, which facilitates the recording of the discharge.

[0061] After the material is received by the second conveyor belt 3a, it will be transported to the fifth elevator 2f and lifted into the metering device 2e. The scale plate 2e4 in the metering device 2e, combined with the photoelectric sensor 2e7, can measure the volume of the conveyed material. When setting, the first motor 2e9 can drive the assembly body 2e8 to rotate. The position of the photoelectric sensor 2e7 at the scale plate 2e4 is observed by the camera 2e6 to make remote settings, so that the metered material can enter the drum screen 2g in batches for secondary screening, further ensuring the quality of the finished product.

[0062] The material after being sieved through the drum screen 2g is lifted by the fourth elevator 2d into the frying feed hopper 2c. Since the frying feed hopper 2c is located on the weighing rack 2h, it can be weighed and fed for frying. After frying, the material is lifted by the discharge filter hopper 2b to the centrifugal oil filter 2a for filtration. After filtration, the material enters the third elevator 1g and is conveyed to the cooling conveying equipment 1f for cooling. After cooling, the material is lifted by the second elevator 1e to the first feeding equipment 1d. The first feeding equipment 1d selects the corresponding first elevator 1c for feeding according to the type and flavor of the material, so that the material is conveyed to the corresponding first conveyor belt 1b, and then conveyed by the first conveyor belt 1b to the corresponding weighing equipment 1a for automatic weighing. Finally, it enters the food packaging machine 1h below the weighing equipment 1a for packaging.

[0063] To achieve fully automated frying production, only a small number of personnel are needed to feed the materials at the eighth elevator 4c in the drying area 4 and to monitor and control the settings in the control center 5. This greatly reduces the number of workers and labor intensity, facilitates continuous production, and better avoids situations such as misplacement and dangerous operation by manual labor, thereby improving production efficiency and quality. At the same time, the combination of feeding equipment and elevators allows for the combined use of different numbers of drying equipment 4f, frying equipment 2i, storage tanks 3b, food packaging machines 1h, etc., which is more convenient for production with different processing times for different processes.
