Description

Technical Field

[0001] The utility model belongs to the technical field of food screw conveyors, and particularly relates to a temperature control system for a food screw conveyor. Background Art

[0002] In the modern food processing industry, efficient and precise processing is crucial. As a common conveying equipment, food screw conveyors play a vital role in food production lines. However, when it comes to heating food, existing food screw conveyors have a series of problems that need improvement.

[0003] Traditional food screw conveyors offer poor temperature control. Their heating methods are typically simple and crude, making it difficult to achieve precise temperature control tailored to the characteristics and processing requirements of individual foods. This can lead to localized overheating or underheating of food during the heating process, affecting not only the quality and taste of the food but also potentially destroying its nutritional value.

[0004] In terms of spiral tine design, the spacing between the tine teeth in typical conveyors is fixed. This prevents flexible adjustment of the food's residence time within the conveyor to meet heating requirements. When sufficient heating is required, the food's travel time within the conveyor is too short, preventing sufficient heating time. This results in suboptimal heating and fails to meet the high standards of food processing.

[0005] At the same time, in the feeding process, food that has not been preheated enters the conveyor directly for heating, which requires more energy and time to achieve the ideal heating effect.

[0006] To this end, we proposed a temperature control system for food spiral conveyors. This device can heat the food evenly and improve the heating effect of the food. At the same time, it recycles heat to preheat the food, reduce energy waste, and improve the heating effect of the food. Utility Model Content

[0007] The purpose of this utility model is to provide a temperature control system for a food spiral conveyor, which can heat the food evenly and improve the heating effect of the food. At the same time, it recycles the heat to preheat the food, reduces the waste of energy and improves the heating effect of the food.

[0008] The technical solutions adopted in this application are as follows:

[0009] A temperature control system for a food screw conveyor comprises a cylinder, wherein the cylinder is provided with a feed pipe, a discharge pipe, a heating ring and a rotating assembly, wherein the rotating assembly is provided with spiral conveying teeth, and a fixed cylinder is provided on one side of the cylinder, wherein a plurality of heat absorbing plates are provided inside the fixed cylinder, wherein half of each heat absorbing plate is located inside the fixed cylinder and the other half is located inside the cylinder, and a conduit is provided on the top of the fixed cylinder, wherein a small fan is provided on the conduit, a conical material guide housing is provided on the top of the feed pipe, a hollow conical material distribution plate connected to the conduit is provided inside the conical material guide housing, and an exhaust pipe and an air guide plate are provided at the bottom of the hollow conical material distribution plate;

[0010] The spiral conveying teeth are divided into an initial section, a middle section and a lead-out section. The spacing between the conveying teeth between the initial section and the middle section gradually increases, and the distance between the conveying teeth in the lead-out section is the same as that in the initial section.

[0011] Furthermore, a heat-insulating layer is provided on the outside of the cylinder.

[0012] Furthermore, a temperature sensor is provided inside the cylinder.

[0013] Furthermore, the rotating assembly includes a motor arranged on the cylinder, the output end of the motor is connected with a rotating shaft, the end of the rotating shaft away from the motor passes through the cylinder, and the spiral conveying teeth are provided on the rotating shaft.

[0014] Furthermore, an air inlet hole is provided on the fixing cylinder.

[0015] Furthermore, the conical material guiding shell is wide at the top and narrow at the bottom, and the hollow conical material distributing plate is narrow at the top and wide at the bottom.

[0016] The technical effects achieved by this utility model are:

[0017] First, when the temperature of the cylinder needs to be controlled and adjusted, the heating ring is controlled by the controller to heat it, so as to achieve temperature adjustment. Then the food inside the conical guide shell enters the cylinder through the feed pipe, and then the spiral conveying teeth are used to convey the food through the rotating assembly. When the food passes through the initial section and the middle section, the distance between the conveying teeth gradually increases, resulting in an increase in the time the food stays inside the cylinder, thereby increasing the time the food is heated, so that the food is heated more comprehensively, and the effect of food heating is improved. When the food moves to the lead-out section, it can be quickly exported and discharged from the discharge pipe. At this time, there is a certain amount of heat inside the cylinder. This heat is absorbed by the heat absorbing plate, so that the heat is introduced into the fixed cylinder, so that the fixed cylinder has a certain amount of heat. Then, the heat is allowed to enter the hollow conical distribution plate through the conduit through the action of the small fan, and then the heat is sprayed into the air guide plate through the exhaust pipe at the bottom. The heat is distributed on the flowing food through the air guide plate, thereby preheating the food, thereby improving the effect of subsequent heating. The device can heat the food evenly, improve the heating effect of the food, and at the same time recycle the heat to preheat the food, thereby reducing energy waste and improving the heating effect of the food.

[0024] In order to make the purpose and advantages of this utility more clear, the utility is described in detail below with reference to the embodiments. It should be understood that the following text is only used to describe one or several specific implementation methods of this utility and does not strictly limit the scope of protection specifically requested by this utility.

[0025] like Figure 1-4As shown, the technical solution adopted in this utility model is specifically as follows: a temperature control system for a food screw conveyor, comprising a cylinder 1, on which a feed pipe 2, a discharge pipe 3, a heating ring 4 and a rotating assembly are provided, and a spiral conveying tooth 5 is provided on the rotating assembly, and a fixed cylinder 6 is provided on one side of the cylinder 1, and a plurality of heat-absorbing sheets 7 are provided inside the fixed cylinder 6, half of each heat-absorbing sheet 7 is located inside the fixed cylinder 6, and the other half is located inside the cylinder 1, and a conduit 8 is provided on the top of the fixed cylinder 6, and a small fan is provided on the conduit 8, a conical material guide shell 9 is provided on the top of the feed pipe 2, and a hollow conical material distribution plate 10 connected to the conduit 8 is provided inside the conical material guide shell 9, and an exhaust pipe 11 and an air guide plate 12 are provided at the bottom of the hollow conical material distribution plate 10;

[0026] The spiral conveying teeth 5 are divided into an initial section 13 , an intermediate section 14 and an outlet section 15 . The spacing between the conveying teeth between the initial section 13 and the intermediate section 14 gradually increases, and the distance between the conveying teeth in the outlet section 15 and the initial section 13 is the same.

[0027] Its working principle is: first, when the temperature of the cylinder 1 needs to be controlled, the heating ring 4 is controlled by the controller to heat, so as to achieve temperature adjustment, and then the food inside the conical guide shell 9 enters the cylinder 1 through the feed pipe 2, and then the spiral conveying teeth 5 are used to convey the food through the rotating assembly. When the food passes through the initial section 13 and the middle section 14, the distance between the conveying teeth gradually increases, resulting in an increase in the time the food stays inside the cylinder 1, thereby increasing the time the food is heated, so that the food is heated more comprehensively, and the effect of food heating is improved. When the food moves to the outlet section 15, it can be quickly discharged and discharged from the discharge pipe 3. At this time, there is a certain amount of heat inside the cylinder 1. This heat is absorbed by the heat absorbing plate 7, so that the heat is introduced into the fixed cylinder 6, so that the fixed cylinder 6 has a certain amount of heat. Then, through the action of the small fan, the heat is allowed to enter the hollow conical distribution plate 10 through the conduit 8, and then the heat is potted into the air guide plate 12 through the exhaust pipe 11 at the bottom. The heat is distributed on the flowing food through the air guide plate 12, thereby preheating the food, thereby improving the effect of subsequent heating. The device can heat the food evenly, improve the heating effect of the food, and at the same time recycle the heat to preheat the food, thereby reducing energy waste and improving the heating effect of the food.

[0028] Among them, a heat-insulating layer is provided on the outside of the cylinder 1, and the heat-insulating effect can be achieved through the heat-insulating layer.

[0029] At the same time, a temperature sensor is provided inside the cylinder 1 , through which the temperature inside the cylinder 1 can be known.

[0030] The heating ring 4 is typically made of cast aluminum, stainless steel, or the like, which have excellent thermal conductivity and corrosion resistance, meeting the hygiene and safety requirements of the food industry. The heating ring 4 needs to fit tightly against the barrel 1 of the screw conveyor to ensure that heat is evenly transferred to the interior of the barrel 1. A heating element, such as a resistance wire, is provided within the heating ring 4, which is conventional and will not be described in detail here.

[0031] The heating ring 4 is connected to an external control system, and the control system is electrically connected to a temperature sensor. When the temperature sensor detects that the cylinder 1 needs to be heated, the information is transmitted to the control system, and the control system controls the heating ring 4 to heat.

[0032] It should be noted that the working principles and circuit operation modes of the heating ring 4, the control system and the temperature sensor all belong to the prior art and will not be described in detail here.

[0033] The rotating assembly includes a motor 16 arranged on the barrel 1, the output end of the motor 16 is connected to the rotating shaft, the end of the rotating shaft away from the motor 16 passes through the barrel 1, and a spiral conveying tooth 5 is provided on the rotating shaft. The rotating shaft is driven by the motor 16 to rotate the spiral conveying tooth 5, thereby conveying food.

[0034] The fixing tube 6 is made of heat-insulating material, so when heat enters the interior of the fixing tube 6 , the heat will not dissipate easily.

[0035] The fixed cylinder 6 is provided with an air inlet hole (not shown in the figure) through which air can circulate.

[0036] There are multiple heat absorbing sheets 7, and the material of the heat absorbing sheets is copper or ceramic, so that the heat absorbing sheets have high heat absorbing performance.

[0037] The conical material guide housing 9 is wide at the top and narrow at the bottom, and the hollow conical material distribution plate 10 is narrow at the top and wide at the bottom. This arrangement allows a flow gap to be provided between the hollow conical material distribution plate 10 and the conical material guide housing 9, thereby dispersing the material.

[0038] The food inside the conical material guide shell 9 enters through the external pipe. When the food enters, it will first come into contact with the conical hollow conical material distribution plate 10, and then be guided by the inclined surface of the hollow conical material distribution plate 10, and then flow out through the flow gap. When flowing out, the hot air is guided by the air guide plate 12, so that the hot air is sprayed on the dispersed materials, so that the food can be preheated quickly.

[0039] It should be noted that the speed of the small fan is not as fast as that of the existing fan. Its function is only to guide air, so when the small fan rotates, it will not rotate so fast. It can be controlled by setting a speed regulating motor 16. This belongs to the existing technology and will not be described in detail here.

[0040] The working principle of the utility model is as follows: when the temperature of the cylinder 1 needs to be controlled and adjusted, the heating ring 4 is controlled by the controller to heat, so as to achieve temperature adjustment, and then the food inside the conical guide shell 9 enters the cylinder 1 through the feed pipe 2, and then the spiral conveying teeth 5 are used to convey the food through the rotating assembly. When the food passes through the initial section 13 and the middle section 14, the distance between the conveying teeth gradually increases, resulting in an increase in the residence time of the food inside the cylinder 1, thereby increasing the heating time of the food, making the food more fully heated, and improving the effect of food heating. When the food moves to the lead-out section 15, it can be quickly discharged and discharged from the discharge pipe 3. At this time, there is a certain amount of heat inside the cylinder 1. This heat is absorbed by the heat absorbing plate 7, so that the heat is introduced into the fixed cylinder 6, so that the fixed cylinder 6 has a certain amount of heat. Then, through the action of the small fan, the heat is allowed to enter the hollow conical distribution plate 10 through the conduit 8, and then the heat is potted into the air guide plate 12 through the exhaust pipe 11 at the bottom. The heat is distributed on the flowing food through the air guide plate 12, thereby preheating the food, thereby improving the effect of subsequent heating. The device can heat the food evenly, improve the heating effect of the food, and at the same time recycle the heat to preheat the food, thereby reducing energy waste and improving the heating effect of the food.

[0041] The above description is only a preferred embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this application shall be implemented in accordance with conventional means in the art unless otherwise specified or limited.
