Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to a distributed intelligent temperature control system for a meat product production line. Background Technology

[0002] In the meat processing industry, temperature control is a core element determining product quality, safety, and shelf life. Meat production involves multiple processes, including marinating, steaming, baking, cooling, and heat preservation. Each process has unique temperature requirements, and the stability and uniformity of temperature directly affect the texture, flavor, and microbial control of the meat products. Excessive temperature can lead to localized charring, nutrient loss, and even the growth of harmful microorganisms; insufficient temperature results in inadequate processing and undercooking, negatively impacting the eating experience and product quality. Therefore, a stable temperature control system adapted to the temperature requirements of each process is a crucial component of the meat processing production line.

[0003] Chinese Utility Model Publication No. CN215506412U discloses an intelligent multi-purpose food processing production line, including a mixing chamber. Protective shells and support bases are fixedly installed at the left and right ends of the mixing chamber, respectively. A drive motor is fixedly installed inside the protective shell in the middle of the left side of the mixing chamber. This intelligent multi-purpose food processing production line, by setting the feeding end of the device to allow simultaneous feeding of different raw materials, and in conjunction with an internal flow sensor, can effectively detect the amount of raw materials fed in real time, maximizing product quality. Simultaneously, the outer ring shell outside the mixing chamber, the gas that can flow into it, and the temperature sensor on the internal stirring head can effectively monitor the temperature changes of the raw materials in real time, ensuring that the raw materials are always within the optimal production temperature range, thereby guaranteeing product quality and demonstrating the practicality of the device.

[0004] However, like traditional meat processing production lines, the aforementioned patents mostly employ a centralized temperature control system. This system, which regulates the entire production line's ambient temperature using a single device, struggles to meet the diverse needs of different processes. Due to the long production line length, centralized systems are prone to heat loss and attenuation during heat transfer, resulting in significant temperature differences between areas. Areas closer to the temperature control equipment tend to be warmer, while areas further away are cooler, making it impossible to guarantee independent and precise temperature control for each process and affecting product quality consistency. Furthermore, traditional systems have simple insulation structures, often consisting of a single layer of insulation material, resulting in poor insulation performance. Heat easily leaks through openings and gaps, increasing the load on the temperature control equipment, raising energy consumption, and negatively impacting the surrounding working environment, hindering operation and stable equipment performance.

[0005] Based on this, this utility model designs a distributed intelligent temperature control system for a meat product production line to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a distributed intelligent temperature control system for meat product production lines.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A distributed intelligent temperature control system for a meat processing production line includes a conveyor belt and a control cabinet. Multiple insulation covers corresponding to the production line are fixedly installed on the conveyor belt along the conveying direction. Each insulation cover has an opening at both ends. A cooling component is fixedly installed on the upper end of the conveyor belt. A temperature sensor is fixedly installed on the front end of the insulation cover. Heating components are fixedly installed on both symmetrical sides inside the insulation cover along the conveying direction of the conveyor belt.

[0009] Furthermore, the cooling assembly includes a cooling air pump, the air inlet of which is connected to a cooling air tank via an air inlet pipe, and an exhaust pipe is fixedly installed at the lower end of the insulation cover. A valve is installed on the exhaust pipe. The cooling air pump can draw gas into the insulation cover through the cooling air tank for cooling, and the hot air inside the insulation cover can be discharged through the exhaust pipe.

[0010] Furthermore, the outlet of the cooling air pump is fixedly connected to an air guide shroud via an air outlet pipe, and the air guide shroud is located at the top inside the heat preservation shroud. The cold air is transported into the heat preservation shroud through the air outlet pipe and then evenly dispersed through the air guide shroud, thereby improving the cooling effect on meat products.

[0011] Furthermore, the cooling gas tank includes a tank body, a tank cover detachably installed on the upper end of the tank body, an activated carbon filter filler filling the inner cavity of the tank body, and an air inlet fixedly installed on the upper end of the tank cover. External gas can be filtered when passing through the activated carbon filter filler to ensure the cleanliness of the gas and prevent contamination of the meat products inside the heat preservation cover.

[0012] Furthermore, the heating assembly includes a hollow box body, on the inside of which a serpentine electric heating tube is fixedly installed. The hollow box body has multiple evenly distributed through holes near the end of the conveyor belt. The serpentine electric heating tube can achieve uniform heating, and the through holes can fully heat the meat products on the conveyor belt.

[0013] Furthermore, the upper areas of the openings at both ends of the heat preservation cover are provided with interlayers. An electromagnet is fixedly installed at the top of the interlayer, and a matching isolation component is slidably installed at the lower end of the interlayer. The lifting and lowering action of the isolation component can be controlled by the magnetic field of the electromagnet, which can realize the closing and opening of the opening. When closed, it can prevent heat leakage and affect other processes. When open, it can allow the conveyor belt to transport meat products normally.

[0014] Furthermore, the isolation assembly includes a partition, the outer surface of which is covered with a heat insulation layer, a magnet is embedded in the upper end of the partition, and a pair of compression springs are fixedly connected between the upper end of the partition and the top wall of the interlayer. The heat insulation layer can fill the gaps to improve the heat insulation effect and at the same time avoid damage to the conveyor belt. The compression springs can be used to buffer the movement of the partition during lifting and lowering.

[0015] Furthermore, the partition is fixedly connected to limit sliders at both ends, and limit grooves matching the limit sliders are provided on both sides of the interlayer. The limit sliders are slidably installed inside the limit grooves. The cooperation between the limit sliders and the limit grooves can improve the stability of the partition when it is raised and lowered, thereby ensuring the sealing performance during heat insulation.

[0016] Beneficial effects

[0017] (1) This system achieves independent and precise temperature control for each process stage through a distributed insulation cover design. Each insulation cover is equipped with an independent temperature sensor, heating component and cooling component, which are adjusted according to the needs of each process. This solves the problem that traditional centralized temperature control is difficult to adapt to different temperature requirements and has poor temperature control uniformity. It ensures that meat products are in the optimal temperature environment in each process, guarantees the stability of taste, flavor and quality, avoids deterioration or processing defects caused by improper temperature, and improves the overall processing quality.

[0018] (2) The heating and cooling components in this system do not interfere with each other. The temperature can be adjusted in real time according to the processing requirements of meat products. The cooling gas can be purified during cooling to avoid impurities from contaminating the meat products.

[0019] (3) This system can quickly control the lifting and lowering of the isolation component by means of an electromagnet, which is used to close and open the opening on the heat preservation cover, reduce heat leakage, reduce the frequent start of the heating component, reduce energy consumption, and at the same time will not affect the normal conveying of meat products by the conveyor belt.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The present invention will be further described below with reference to the embodiments.

[0030] In some embodiments, please refer to the appendix to the instruction manual. Figures 1-5 A distributed intelligent temperature control system for a meat product production line includes a conveyor belt 1 and a control cabinet 2. Multiple insulation covers 3 corresponding to the production line are fixedly installed on the conveyor belt 1 along the conveying direction. Openings 4 are provided at both ends of the insulation covers 3. Cooling components 5 are fixedly installed on the upper end of the conveyor belt 1. Temperature sensors 7 are fixedly installed on the front end of the insulation covers 3. Heating components 6 are fixedly installed on both sides of the insulation covers 3 symmetrically along the conveying direction of the conveyor belt 1.

[0031] The conveyor belt 1 is made of food-grade 304 stainless steel, which is resistant to high temperatures and corrosion, meets food contact hygiene standards, and can withstand the weight of meat products and temperature changes in each heat preservation hood 3 area. The surface is polished to reduce meat residue and facilitate cleaning. Its drive is controlled by a variable frequency motor inside the control cabinet 2, powered by the production line's 380V industrial power supply. The conveying speed is adjusted by the frequency converter inside the control cabinet 2 to adapt to the temperature control time requirements of different processes.

[0032] The control cabinet 2 integrates core components such as a PLC controller, relays, contactors, power modules, and a human-machine interface. Power is supplied via a 380V three-phase five-wire system. The PLC controller, as the system core, receives signals from the temperature sensor 7 and controls the operation of the heating assembly 6, cooling assembly 5, and electromagnet 8. The human-machine interface allows for parameter settings such as target temperatures and cooling times for each insulation cover 3, as well as status displays such as real-time temperature and equipment operating status. Relays and contactors control the power supply to electrically connected components, ensuring circuit safety.

[0033] The cooling assembly 5 includes a cooling air pump 51. The air inlet of the cooling air pump 51 is connected to a cooling air tank 53 through an air inlet pipe 52. An exhaust pipe 54 is fixedly installed at the lower end of the insulation cover 3. A valve 55 is installed on the exhaust pipe 54. The cooling air pump 51 can draw gas into the insulation cover 3 through the cooling air tank 53 for cooling. The hot air inside the insulation cover 3 can be discharged through the exhaust pipe 54.

[0034] The outlet of the cooling air pump 51 is fixedly connected to the air guide shroud 57 through the air outlet pipe 56. The air guide shroud 57 is located at the top inside the heat preservation cover 3. The cold air is delivered to the heat preservation cover 3 through the air outlet pipe 56 and then evenly dispersed through the air guide shroud 57, thereby improving the cooling effect on meat products.

[0035] The cooling gas tank 53 includes a tank body 531, a tank cover 532 that is detachably installed on the upper end of the tank body 531, an activated carbon filter filler 533 filling the inner cavity of the tank body 531, and an air inlet 534 that is fixedly installed on the upper end of the tank cover 532. External gas can be filtered when passing through the activated carbon filter filler 533 to ensure the cleanliness of the gas and avoid contaminating the meat products inside the heat preservation cover 3.

[0036] The cooling air pump 51 is a stainless steel casing vortex air pump with low noise and stable air pressure. It is powered by 380V industrial power and its start / stop and speed are controlled by a PLC in control cabinet 2 via relays. Speed ​​adjustment changes the airflow to control the cooling rate. The air inlet pipe 52 is made of food-grade silicone tubing, which is heat-resistant, aging-resistant, and has a smooth inner wall that prevents dust accumulation, thus avoiding the introduction of impurities during gas delivery. The cooling air tank 53's body 531 is made of 304 stainless steel. The tank cover 532 is threaded to the tank body 531, and a food-grade silicone sealing ring is installed at the connection to ensure a tight seal. The air inlet 534 on the tank cover 532 is equipped with a one-way valve to prevent backflow of filtered gas. The inner cavity of the tank body 531 is filled with columnar activated carbon filter media 533, which has a large specific surface area and can effectively filter dust, odors, and other impurities in the air, ensuring the cleanliness of the cooling gas entering the insulation hood 3 and preventing contamination of meat products. The exhaust pipe 54 is made of food-grade stainless steel, and the valve 55 is a 220V electric butterfly valve controlled by a PLC. When the cooling assembly 5 is working, the valve 55 opens, expelling hot air from the insulation cover 3 to form an airflow circulation, thus improving the cooling effect. The exhaust pipe 56 is made of the same material as the intake pipe 52, and the air guide shroud 57 is made of food-grade 304 stainless steel. It is trumpet-shaped with multiple evenly spaced air outlets at the bottom, which can evenly distribute cold air into the insulation cover 3 to ensure uniform cooling of meat products.

[0037] The heating component 6 includes a hollow box 61, on which a serpentine electric heating tube 62 is fixedly installed. The hollow box 61 has multiple evenly distributed through holes 63 at one end near the conveyor belt 1. The serpentine electric heating tube 62 can achieve uniform heating, and the through holes 63 can fully heat the meat products on the conveyor belt 1.

[0038] The serpentine electric heating element 62 uses a nickel-chromium alloy heating wire, encased in a food-grade stainless steel sleeve. It boasts high heating efficiency, high temperature resistance, and a long lifespan. Powered by 380V, the heating power is controlled by a PLC within control cabinet 2 via a solid-state relay. This relay allows for stepless voltage adjustment, preventing sudden temperature rises and falls. The circular through-holes 63 on the hollow housing 61 are designed with precise diameter and distribution density to ensure even heat radiation to the surface of the meat products, achieving thorough heating and preventing localized charring.

[0039] In some embodiments, the left and right ends of the heat insulation cover 3 are provided with a sandwich layer corresponding to the upper area of ​​the opening 4. An electromagnet 8 is fixedly installed at the top of the sandwich layer, and a matching isolation component 9 is slidably installed at the lower end of the sandwich layer. The lifting and lowering action of the isolation component 9 can be controlled by the magnetic field of the electromagnet 8, so as to realize the closing and opening of the opening 4. When closed, heat leakage can be avoided and other processes can be prevented. When open, the conveyor belt 1 can be allowed to transport meat products normally.

[0040] Temperature sensor 7 uses a PT100 platinum resistance temperature sensor, which has high measurement accuracy and good stability. The probe part is made of food-grade stainless steel shell and directly contacts the air inside the insulation cover 3 to detect the temperature in real time. It is connected to the PLC through a shielded wire to convert the temperature signal into an electrical signal for transmission. The power supply is a 24V DC power supply provided by the switching power supply in the control cabinet 2 to ensure that the detection signal is stable and not interfered with.

[0041] Electromagnet 8 is a DC electromagnet with a stainless steel outer shell to prevent rust. The coil uses high-temperature resistant enameled wire to prevent overheating damage. It is powered by a 24V DC power supply provided by the switching power supply in the control cabinet 2. The PLC controls its power on and off via a relay. When powered on, it generates a magnetic field that attracts the magnet 93 of the isolation component 9, causing the partition 91 to rise and open the opening 4. When powered off, the magnetic field disappears, and the partition 91 falls and closes the opening 4 under the action of the compression spring 95.

[0042] The insulation cover 3 has a double-layer stainless steel plate structure. Both the outer and inner layers are made of 304 stainless steel, with the inner layer being made of food-grade material. The middle layer is filled with high-temperature resistant aluminum silicate insulation cotton, ensuring insulation performance, reducing heat loss, and meeting food hygiene requirements. It is connected to the supports on both sides of the conveyor belt 1 by bolts, ensuring stable operation without shaking. The openings 4 at both ends are sized to match the width of the conveyor belt 1, allowing meat products to pass through. The upper layer of the openings 4 is a stainless steel cavity structure, integrally formed with the insulation cover 3, providing installation space for the electromagnet 8 and the isolation assembly 9.

[0043] The isolation component 9 includes a partition 91, the outer surface of which is covered with a heat insulation layer 92. A magnet block 93 is embedded in the upper end of the partition 91. A pair of compression springs 95 are fixedly connected between the upper end of the partition 91 and the top wall of the interlayer. The heat insulation layer 92 can fill the gaps to improve the heat insulation effect and at the same time avoid damage to the conveyor belt 1. The compression springs 95 can be used to buffer the movement of the partition 91 during lifting.

[0044] Limiting sliders 94 are fixedly connected to both ends of the partition 91. Limiting grooves matching the limiting sliders 94 are provided on both sides of the interlayer. The limiting sliders 94 are slidably installed inside the limiting grooves. The cooperation between the limiting sliders 94 and the limiting grooves can improve the stability of the partition 91 when it is raised and lowered, thereby ensuring the sealing performance during heat insulation.

[0045] The partition 91 is made of polyetheretherketone (PEEK) high-temperature resistant engineering plastic, which is heat-resistant, has good mechanical strength, and is lightweight, facilitating lifting and lowering. The heat insulation layer 92 is ceramic fiber cotton, wrapped around the outer surface of the partition 91, providing excellent heat insulation performance, preventing heat loss, and its soft texture avoids scratch damage when in contact with the conveyor belt 1. The magnet block 93 is a neodymium iron boron strong magnet, embedded in the groove at the upper end of the partition 91 and fixed with high-strength adhesive to ensure the attraction force with the electromagnet 8. The limit slider 94 is made of polytetrafluoroethylene wear-resistant engineering plastic, fixed at both ends of the partition 91, and cooperates with the stainless steel limit slide grooves on both sides of the interlayer to ensure smooth and vertical lifting of the partition 91 and ensure a tight seal. The compression spring 95 is a stainless steel cylindrical helical spring with good elasticity and corrosion resistance. Its two ends are welded to the top wall of the interlayer and the upper end of the partition 91, respectively. When the electromagnet 8 is energized, the spring is compressed to store potential energy. When the power is off, the potential energy is released to push the partition 91 down slowly, playing a buffering role and avoiding collision damage.

[0046] Working principle:

[0047] The system sets parameters such as the target temperature of each heat preservation cover 3, the conveying speed of the conveyor belt 1, the cooling time of the cooling component 5, and the heating power of the heating component 6 through the human-machine interface of the control cabinet 2. After the settings are completed, the system starts and the conveyor belt 1 runs along the conveying direction under the drive of the variable frequency motor in the control cabinet 2, and conveys the meat products to be processed to each heat preservation cover 3 in sequence.

[0048] When meat products are about to enter a certain heat preservation cover 3, the PLC in the control cabinet 2 controls the electromagnets 8 in the upper interlayer of the openings 4 at both ends of the heat preservation cover 3 to be energized in advance according to the speed and position signal of the conveyor belt 1. The electromagnets 8 generate a magnetic field to attract the magnet blocks 93 of the isolation component 9, which drives the partition 91 to slide upward along the limiting slide groove. The limiting slide grooves on both sides of the interlayer and the limiting sliders 94 at both ends of the partition 91 cooperate to form an upward sliding. At this time, the compression spring 95 is compressed, the opening 4 is opened, and the meat products are allowed to enter the heat preservation cover 3.

[0049] After the meat products have completely entered the insulation cover 3, the PLC controls the electromagnet 8 to be de-energized, the magnetic field disappears, the compression spring 95 releases elastic potential energy, and pushes the partition 91 to slowly descend until the heat insulation layer 92 is in contact with the surface of the conveyor belt 1, sealing the opening 4 to prevent heat leakage and mutual interference with the temperature environment of the adjacent insulation cover 3.

[0050] Subsequently, the temperature sensor 7 at the front end of the insulation cover 3 detects the temperature inside the cavity in real time and transmits the signal to the PLC in the control cabinet 2 through a shielded wire. The PLC compares the real-time temperature with the target temperature: if the real-time temperature is lower than the target temperature, the PLC controls the serpentine electric heating tube 62 of the heating component 6 to be energized and heated through a solid-state relay. The heat is radiated to the surface of the meat products through the through hole 63 of the hollow box 61. The PLC adjusts the heating power according to the temperature difference to maintain a stable temperature. If the real-time temperature is higher than the target temperature, the PLC controls the cooling air pump 51 to start through a relay and opens the valve 55 of the exhaust pipe 54 at the same time. The cooling air pump 51 draws gas purified by the activated carbon filter packing 533 from the cooling air tank 53 and sends the cold air evenly into the insulation cover 3 through the exhaust pipe 56 and the air guide hood 57. The hot air is discharged through the exhaust pipe 54 to form a circulation. The PLC adjusts the speed of the cooling air pump 51 according to the temperature difference to control the cooling rate. If the temperature reaches the target, the heating component 6 and the cooling component 5 are in standby mode.

[0051] After the meat products have undergone temperature control, the PLC, based on the speed and dwell time of the conveyor belt 1, pre-energizes the electromagnets 8 at both ends of the insulation cover 3. This causes the partition 91 to rise and open the opening 4, allowing the conveyor belt 1 to transport the meat products to the next insulation cover 3 or out of the production line, completing the temperature control process. During operation, the human-machine interface displays the real-time temperature and equipment status of each insulation cover 3. If a component malfunctions, the PLC triggers an alarm and displays the fault type, facilitating troubleshooting and maintenance.

[0052] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
