A pump (not shown in the figure) is connected to a steam source 12 through a pipeline, a steam regulating valve 9, an automatic steam stop valve 10, and a manual stop valve 11 at the steam inlet of the tubular heat exchanger 8. The condensate outlet of the tubular heat exchanger 8 is connected to a condensate pipe. A steam trap 14, a one-way valve 15 and a condensate stop valve 16 are sequentially arranged on the condensate pipe along the flow direction. The one-way flow direction of the one-way valve 15 is from the steam trap 14 to the condensate stop valve 16. The output end of the temperature sensor 7, the automatic steam stop valve 10, and the control end of the steam regulating valve 9 are all connected to a controller (not shown in the figure).

[0012] Furthermore, the inner tube 2 and the outer tube 1 are both made of SS316L steel pipes, which are more wear-resistant and corrosion-resistant.

[0013] Furthermore, the inner tube 2 is fixed to the material inlet 3 and the material outlet 4 by welding to reduce the risk of leakage.

[0014] Furthermore, the tubular heat exchanger 8, manual stop valve 11, steam automatic stop valve 10, steam regulating valve 9, steam trap 14, one-way valve 15, and condensate stop valve 16 are installed on a supporting frame (not shown in the figure) to reduce the size of the equipment and install it next to the equipment that needs to use the material constant temperature device.

[0015] Specifically, the outer sleeve 1, the inner tube 2, the tubular heat exchanger 8, the water source 13, the water supply valve 17, the temperature sensor 7, the steam regulating valve 9, the steam automatic stop valve 10, the manual stop valve 11, the steam trap 14, the one-way valve 15, the condensate stop valve 16, the controller, the SS316L steel pipe, etc. in this embodiment all adopt the well-known solutions in the prior art, which are well understood by those skilled in the art and will not be described herein.

[0016] The working principle of this embodiment:

[0017] Before the equipment is put into operation, the pipeline is first filled with water. The specific operation is to open the water supply valve 17, enter the outer casing 1, and drive the water to circulate between the outer casing 1 and the tubular heat exchanger 8 through the water pump. Open the steam manual stop valve 11 and the steam automatic stop valve 10 to pass steam, and heat the circulating water through the tubular heat exchanger 8. The temperature sensor 7 can accurately measure the temperature of the hot water. Under the control of the controller, the steam regulating valve 9 is linked with the temperature sensor 7 to adjust the opening of the steam regulating valve 9, thereby regulating the hot water temperature. When the hot water temperature reaches the required temperature, the steam opening is reduced and the heating is stopped. At this time, the material begins to enter from the material inlet of the inner tube 2. The hot water in the outer casing 1 keeps the material temperature constant, compensates for the temperature loss of the product during the transportation process, and meets the heating requirements in the product processing. The condensed water of the tubular heat exchanger 8 is discharged through the steam trap 14, the one-way valve 15, and the condensed water stop valve 16.

[0018] The water supply valve 17 adopts food-grade sanitary design and uses SS316L material, which is wear-resistant and corrosion-resistant. All sealing rings meet FDA certification and are made of EPDM material. It does not require pneumatic actuators and control systems, and has low costs; low maintenance costs, only regular inspections of the seal usage are required; high stability and not prone to failure.

[0019] The steam manual stop valve 11, the steam automatic stop valve 10, the steam regulating valve 9, the steam trap 14, the check valve 15, and the condensate stop valve 16 constitute a steam valve group, which can heat the hot water that does not meet the temperature standard to the required temperature and automatically control the entry of steam. The steam regulating valve 9 is linked with the temperature sensor 7 to accurately achieve temperature control. The check valve 15 can prevent the condensate from returning to the tubular heat exchanger 8 to produce a steam-water mixture. The steam trap 14 can timely transport the condensate generated by the steam condensation to improve the heat exchange efficiency.

[0020] The utility model is a material constant temperature device, which uses a tubular heat exchanger 8 as a heat exchange component, and realizes efficient heat exchange of materials through the circulation of hot water and steam, thereby reducing energy consumption. Through the linkage of the steam regulating valve 9 and the temperature sensor 7, the steam opening is accurately controlled, thereby realizing accurate regulation of the hot water temperature, improving the constant temperature effect, and reducing the complexity of operation.
