The reason why heat tracing belt is used in food display cases

　　With the development of modern commerce, food display cases have become an indispensable part of supermarkets, convenience stores and other retail places. The food showcase can not only display food, but also keep the freshness and taste of food. However, in the cold winter, the glass doors and display shelves of food display cabinets are prone to frost, which affects the display effect of food and the shopping experience of customers. As a kind of anti-freezing and heat preservation method, the heat tracing belt is used to prevent frost and deice food display cabinets. The use of heat tracing tape can ensure the normal operation of food display cabinets and the shopping experience of customers. This paper will discuss in detail the reasons why heat tracing tape is used in food display cabinets.

　　First, the environmental characteristics of food display cabinets

　　Food display cases are usually placed in conspicuous positions in supermarkets, convenience stores and other retail places for displaying and selling various foods. In order to keep the freshness and taste of food, food display cabinets are usually equipped with a refrigeration system, which can keep the internal temperature within a suitable range. However, in the cold winter, the glass doors and display shelves of food display cabinets are prone to frost, which affects the display effect of food and the shopping experience of customers. At the same time, frosting will also reduce the refrigeration efficiency of food display cabinets and increase energy consumption and operating costs.

　　Second, the characteristics and advantages of the tropical zone

　　1. Efficient anti-frost and deicing effect.

　　Heat tracing belt is a kind of heating equipment realized by electric heat conduction technology, which can effectively prevent the freezing of pipes and equipment. Installing heat tracing belts on the glass doors and display shelves of food display cabinets can ensure that the temperature of these parts is maintained in a suitable range and avoid frosting. At the same time, the heating effect of the tracing belt is uniform, which can realize the comprehensive coverage of the glass door and the display shelf, and ensure the optimization of the anti-frost and deicing effect.

　　2. Flexible installation method

　　The installation method of the heat tracing belt is very flexible. According to the size and shape of the food display case, you can choose the appropriate type and specification of the heat tracing belt to ensure that the glass door and the display shelf can be completely covered to achieve uniform heating. When installing the heat tracing tape on the glass door and display shelf of the food display case, the heat tracing tape can be directly laid flat on the surface and attached to the surface, which is beneficial to the heat conduction of the heat tracing tape, and the purpose of heat preservation and antifreeze can be achieved by fixing it with the electric heat tracing tape junction box and adhesive tape.

　　3. Automatic temperature control

　　The heat tracing system is usually equipped with intelligent controllers and sensors, which can realize automatic temperature control of glass doors and display shelves. When the temperature of the glass door and the display shelf is lower than the set value, the controller will automatically start the tracing belt for heating; When the temperature reaches the set value, the controller will automatically stop heating. In this way, users do not need to manually adjust the temperature frequently, which reduces the workload and difficulty of maintenance.

　　4. Environmental protection and energy saving

　　The heat tracing system is usually equipped with intelligent controllers and sensors, which can realize automatic temperature control of glass doors and display shelves. The heat tracing system can accurately control the heating time and heating quantity according to the actual needs, thus avoiding the waste of energy and improving the energy utilization efficiency. At the same time, the tracing system does not need to burn fuel, and will not produce harmful gases and pollutants, which meets the current requirements for environmental protection.

　　Third, the application case of the tropical belt in the food display case

　　During the operation of a supermarket in winter, frosting often occurs on the glass doors and display shelves of food display cabinets, which affects the display effect of food and the shopping experience of customers. In order to solve this problem, the supermarket adopted a tracing belt to frost and deice the glass doors and display shelves of food display cabinets. After a period of operation, it is found that the frosting phenomenon of food display cabinets has been effectively solved, and the display effect of food and the shopping experience of customers have been obviously improved.

　　As an efficient thermal insulation solution, the heat tracing belt has the characteristics of high-efficiency frost and deicing effect, flexible installation mode, automatic temperature control, environmental protection and energy saving. By installing heat tracing belts on the glass doors and display shelves of food display cabinets, the problem of frosting can be effectively solved, and the normal operation of food display cabinets and the shopping experience of customers can be guaranteed. At the same time, the application of heat tracing can also prolong the service life of food display cabinets, reduce maintenance costs and improve economic benefits. Therefore, in the process of the construction and operation of food display cabinets, the application prospect of tropical belts is broad.
