Description

Technical Field

[0001] This utility model relates to the field of soybean lecithin oil technology, and in particular to a constant temperature control device for soybean lecithin oil insulation. Background Technology

[0002] Soybean lecithin oil, a natural surfactant extracted from soybean oil by-products, is rich in active ingredients such as phosphatidylcholine and phosphatidylethanolamine. It is widely used in the food, pharmaceutical, cosmetic, and feed industries. Its core functions include emulsification, anti-oxidation, lowering blood lipids, and improving cell membrane fluidity. In particular, its demand as a functional additive continues to grow in the health food sector.

[0003] When the storage temperature of soybean lecithin oil is below its melting point, the lecithin is prone to crystallization or gelation. When the storage temperature of soybean lecithin oil is too high, the high temperature accelerates the oxidation reaction of unsaturated fatty acid chains, generating harmful substances such as peroxides and aldehydes, reducing the nutritional value of the product and producing off-odors, which is not conducive to the storage of soybean lecithin oil. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a constant temperature control device for soybean lecithin oil insulation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A constant temperature control device for soybean lecithin oil insulation includes an insulation tank. The side wall of the insulation tank is composed of an inner layer and an outer layer, with an interlayer between the inner and outer layers. Heat transfer oil is injected into the interlayer, and several support rings are arranged in the interlayer. Spiral heating tubes are fixedly inserted into the support rings and located in the interlayer. A temperature sensor is embedded in the inner wall of the insulation tank, and a temperature display and a control box are arranged on the outer wall of the insulation tank. The temperature display, temperature sensor, and control box are electrically connected. A motor is fixedly installed on the top of the insulated tank. The motor drives a rotating shaft located inside the insulated tank, and three sets of stirring blades are fixedly installed on the rotating shaft.

[0006] Furthermore, a preferred structure is that the inner layer is made of high-density silica.

[0007] Furthermore, a preferred structure is that the outer layer is made of galvanized steel sheet.

[0008] In addition, a preferred structure is that the insulated tank has an inlet pipe on one side of the upper part and an outlet pipe at the bottom of the insulated tank.

[0009] In addition, a preferred structure is that an oil inlet pipe is provided at the upper end of the interlayer, an oil outlet pipe is provided at the lower end of the interlayer, and a filter assembly is threaded onto the oil inlet pipe.

[0010] In addition, a preferred structure is that the filter assembly includes a filter tube, with slots on both sides of the inner wall of the filter tube, and T-shaped limiting grooves on both sides of one end of the filter tube. The T-shaped limiting grooves are connected to the slots, and a T-shaped limiting block is installed in the T-shaped limiting groove by screws.

[0011] In addition, a preferred structure is that the filter tube is provided with filter screen two and filter screen one, and both ends of filter screen two and filter screen one are connected by connecting rods. The connecting rods are slidably inserted into the slots, and one end of the connecting rods is tightly fitted with one end of the T-shaped limiting block.

[0012] In addition, a preferred configuration is that one end of the filter tube is fitted with a cap.

[0013] The beneficial effects of this utility model are as follows: In this invention, the heat-conducting oil in the jacket is heated by a spiral heating tube, and the temperature of the heat-conducting oil is kept within a constant range. This heat is then transferred to the soybean lecithin oil in the heat preservation tank, which can achieve constant temperature preservation of the soybean lecithin oil and is beneficial for storing soybean lecithin oil.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-6 A constant temperature control device for soybean lecithin oil insulation includes an insulation tank 1. The side wall of the insulation tank 1 is composed of an inner layer 16 and an outer layer 17. An interlayer 14 is provided between the inner layer 16 and the outer layer 17. Heat transfer oil is injected into the interlayer 14. Several support rings 5 ​​are provided in the interlayer 14. A spiral heating tube 4 is fixedly inserted into the support rings 5 ​​and located in the interlayer 14. A temperature sensor 6 is embedded in the inner wall of the insulation tank 1. A temperature display 9 and a control box 3 are provided on the outer wall of the insulation tank 1. The temperature display 9, temperature sensor 6 and control box 3 are electrically connected. Among them, a motor 2 is fixedly installed on the top of the heat preservation tank 1, and a rotating shaft 21 is installed inside the heat preservation tank 1 driven by the motor 2. Three sets of stirring blades 7 are fixedly installed on the rotating shaft 21.

[0018] Meanwhile, the inner layer 16 is made of high-density silicate and the outer layer 17 is made of galvanized steel sheet to reduce heat loss.

[0019] Meanwhile, an inlet pipe 11 is provided on one side of the upper part of the heat preservation tank 1, and an outlet pipe 15 is provided at the bottom of the heat preservation tank 1 to facilitate the injection and discharge of soybean lecithin oil.

[0020] Meanwhile, an oil inlet pipe 12 is provided at the upper end of the jacket 14, and an oil outlet pipe 13 is provided at the lower end of the jacket 14. A filter assembly 8 is threaded onto the oil inlet pipe 12 to facilitate the injection and discharge of heat transfer oil.

[0021] Furthermore, the filter assembly 8 includes a filter tube 81, with slots 811 on both sides of the inner wall of the filter tube 81, and T-shaped limiting grooves 812 on both sides of one end of the filter tube 81. The T-shaped limiting grooves 812 are connected to the slots 811, and T-shaped limiting blocks 85 are installed in the T-shaped limiting grooves 812 by screws.

[0022] Meanwhile, filter tube 81 is equipped with filter screen 2 82 and filter screen 1 83. Both ends of filter screen 2 82 and filter screen 1 83 are connected by connecting rod 84. The connecting rod 84 is slidably inserted into slot 811. One end of the connecting rod 84 is tightly fitted with one end of T-shaped limiting block 85. T-shaped limiting block 85 limits the connecting rod 84. Filter screen 2 82 and filter screen 1 83 filter impurities in the heat transfer oil and prevent impurities from adhering to the surface of spiral heating tube 4 and thus affecting heat transfer efficiency.

[0023] Furthermore, a cover 86 is fitted onto one end of the filter tube 81.

[0024] In this embodiment, soybean lecithin oil enters the heat-conducting tank 1 through the inlet pipe 11. Then, the spiral heating tube 4 is activated to heat the heat-conducting oil, keeping its temperature within a constant range. The temperature sensor 6 monitors the temperature of the soybean lecithin oil in real time and displays it on the temperature display 9. When the temperature is too low, the control box 3 increases the power of the spiral heating tube 4, thereby raising the temperature of the heat-conducting oil. The heat generated by the heat-conducting oil is transferred to the soybean lecithin oil in the heat-conducting tank 1. At the same time, the motor 2 is activated to drive the rotating shaft 21 to rotate at a constant speed, which in turn drives the stirring blade 7 to rotate synchronously. The stirring blade 7 stirs the soybean lecithin oil, making the soybean lecithin oil heated evenly, promoting the homogenization of components, improving product quality, and preventing the soybean lecithin oil from settling at the bottom of the heat-conducting tank 1. This achieves constant temperature preservation of the soybean lecithin oil. Heat transfer oil is injected into the jacket 14. The heat transfer oil first passes through filter screen 1 83 and filter screen 2 82, and then enters the jacket 14 through the oil inlet pipe 12. Impurities in the heat transfer oil are trapped to prevent them from adhering to the surface of the spiral heating tube 4 and thus affecting the heat transfer efficiency. At the same time, the filter assembly 8 can be removed by turning the filter tube 81. Then, the screw is turned to remove the T-shaped limiting block 85 from the T-shaped limiting groove 812, and the filter screen 1 83 and filter screen 2 82 can be removed for cleaning.

[0025] In this invention, the heat-conducting oil in the jacket 14 is heated by the spiral heating tube 4 and the temperature of the heat-conducting oil is kept within a constant range, thereby transferring heat to the soybean lecithin oil in the heat preservation tank 1. This allows for constant temperature preservation of the soybean lecithin oil, which is beneficial for storing soybean lecithin oil.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
