Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a device for uniformly spraying oil onto the surface of a low-fat meal replacement biscuit. Background Technology

[0002] In the production process of weight-loss meal replacement biscuits, oil spraying is usually required on the surface of the biscuits to improve their taste and flavor.

[0003] Traditional spray painting equipment has several significant drawbacks. First, the spraying is often uneven, resulting in some cookies being over-sprayed while others are under-sprayed, affecting product consistency. Second, a large number of atomized oil droplets escape into the air, not only wasting oil and increasing production costs, but also polluting production equipment and the workshop environment, posing cleanliness and safety hazards. Furthermore, traditional equipment lacks intelligent control, failing to precisely spray oil based on the actual location and quantity of the cookies, further exacerbating oil waste and unevenness.

[0004] Therefore, there is an urgent need for a device that can achieve uniform oil spraying, efficient recovery and utilization of spilled grease, and a high degree of automation. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a device for uniformly spraying oil onto the surface of a low-fat meal replacement biscuit.

[0006] The technical solution of this utility model is: a device for uniformly spraying oil on the surface of a low-fat meal replacement biscuit, including a frame, a conveying groove on the frame, a conveying mechanism for conveying biscuits in the conveying groove, and an oil storage tank at the bottom of the frame. The negative pressure collection mechanism is installed on the frame. In operation, the negative pressure collection mechanism collects and filters the atomized oil droplets that have escaped. The oil pump is mounted on the frame. When in operation, the oil pump draws filtered grease from the negative pressure collection mechanism. The protective cover is mounted on the frame. A flow guide seat is installed on the inner side of the protective cover. The input end of the flow guide seat is connected to the output end of the oil pump. Several discharge pipes are spaced apart on the flow guide seat. Each discharge pipe is equipped with a solenoid valve for controlling its channel switch. Each discharge pipe is connected to an atomizing nozzle. And the sub-guide frame, which is set on the protective cover and close to the input end of the conveying trough.

[0008] Preferably, the conveying mechanism includes a conveyor belt and a drive assembly for driving the conveyor belt, the conveyor belt being a mesh conveyor belt, and side grooves located on both sides of the conveyor belt.

[0009] Preferably, an installation plate is provided on the inner wall of the conveying trough, and a scraper is provided on the installation plate for scraping off the grease on the surface of the conveyor belt and guiding the grease into the through hole.

[0010] Preferably, the negative pressure collection mechanism includes an oil storage tank, a feed pipe, a blower, a receiving hopper, and a filter. The oil storage tank is connected to the frame. One end of the feed pipe is inserted into the oil storage tank and located below the liquid surface. An exhaust port is provided on the oil storage tank, located above the liquid surface. An oil-gas separator is installed inside the exhaust port. The blower body is mounted on the frame.

The drive roller 31 and the driven roller 32 are located at both ends of the conveying trough 101 and are rotatably connected to the frame 1. The conveyor belt 2 drives the drive roller 31 and the driven roller 32. The body of the servo motor 33 is mounted on the frame 1, and the output end of the servo motor 33 is connected to the roller shaft of the drive roller 31 through a coupling. The negative pressure collection mechanism is mounted on the frame 1. The input end of the negative pressure collection mechanism is connected to the through hole 103. The negative pressure collection mechanism includes an oil storage tank 4, a feed pipe 5, a fan 7, a receiving hopper 8, and a filter 10. The oil storage tank 4 is connected to the frame 1. One end of the feed pipe 5 is inserted into the oil storage tank 4 and is located below the liquid surface. An exhaust hole is provided on the oil storage tank 4, located above the liquid surface. An oil-gas separator 6 is installed inside the exhaust hole. The blower 7 is mounted on the frame 1. Its output is connected to the outside, and its input is connected to the output of the oil-gas separator 6. A receiving hopper 8 is installed outside the through-hole 103. Its output is connected to the upper end of the feed pipe 5. A slide 9 is installed on the receiving hopper 8, inserted along its side. The slide 9 has a guide hole adapted to the inner cavity of the receiving hopper 8. A filter 10 is installed inside the guide hole. The negative pressure collection mechanism collects and filters the atomized oil droplets during operation. An oil pump 11 is mounted on the frame 1. Its input is connected to a suction pipe, the other end of which is inserted into the oil storage tank 4 and positioned below the liquid level. During operation, the oil pump 11 draws filtered grease from the negative pressure collection mechanism. A protective cover 12 is mounted on the frame 1. A through hole 103 is located below the inner cavity of the protective cover 12. A flow guide seat 13 is mounted on the inner side of the protective cover 12. The input end of the flow guide seat 13 is connected to the output end of the oil pump 11. Several discharge pipes 14 are spaced apart on the flow guide seat 13. Each discharge pipe 14 is equipped with a solenoid valve 15 for controlling its channel switch. Each discharge pipe 14 is connected to an atomizing nozzle 16. A guide frame 17 is mounted on the protective cover 12 and close to the input end of the conveying trough 101. Several guide grooves 171 are evenly spaced on the guide frame 17. A detection probe 18 is mounted at the top of each guide groove 171. The detection probe 18 is, but is not limited to, a photoelectric sensor. A controller is mounted on the protective cover 12. The controller is, but is not limited to, a PLC controller. The controller is electrically connected to the detection probes 18 and each solenoid valve 15.

[0018] It should be noted that this technical solution also includes a control panel, which uses a combination of HMI (Human Machine Interface) and PLC (Programmable Logic Controller). The HMI provides users with an intuitive and user-friendly interface, allowing them to easily issue various commands by touching the screen.

[0019] In this invention, the drive assembly 3 is driven by a servo motor 33, which drives the active roller 31 and the driven roller 32 to move the conveyor belt 2, transporting the biscuits from the input end to the output end. During the transport process, the biscuits first pass through a guide frame 17, on which multiple guide grooves 171 are spaced apart. A detection probe 18 (such as a photoelectric sensor) is installed at the top of each guide groove 171 to detect the position and quantity of the biscuits in real time. The detection signal is transmitted to a controller (such as a PLC controller). A protective cover 12 covers the conveying trough 101 and has a guide seat 13 inside. The guide seat 13 is connected to the output end of the oil pump 11, and the input end of the oil pump 11 is inserted below the liquid surface of the oil storage tank 4 through a suction pipe. When the oil pump 11 is working, it draws filtered oil from the oil storage tank 4 and transports it to the guide seat 13. Multiple discharge pipes 14 are connected at intervals on the guide seat 13, and each discharge pipe 14 is equipped with a solenoid valve 15 and an atomizing nozzle 16. The controller, based on the signal from the detection probe 18, controls the opening and closing of the corresponding solenoid valve 15, enabling the atomizing nozzle 16 to precisely and evenly spray oil onto the biscuit surface. During the oil spraying process, some atomized oil droplets may escape. A negative pressure collection mechanism is responsible for recovering these escaped oil droplets, which includes a receiving hopper 8, a feed pipe 5, a blower 7, and an oil storage tank 4. The receiving hopper 8 is covered by a through hole 103, which connects to the conveying trough 101 and the side trough 102. The blower 7 is connected to the exhaust port of the oil storage tank 4 through an oil-gas separator 6. When the blower 7 is working, it generates negative pressure in the oil storage tank 4, causing the escaped oil mist to be drawn into the oil storage tank 4 through the receiving hopper 8 and the feed pipe 5. A carriage 9 and a filter 10 are installed inside the receiving hopper 8. The filter 10 filters the oil mist and removes impurities. The recovered grease settles in the oil storage tank 4 and can be reused by the oil pump 11, forming a grease circulation system and reducing waste.
