Application of electric heat tracing in food processing equipment

In the food processing industry, maintaining the right temperature is essential to ensure product quality, production efficiency and food safety. As an effective means of temperature control, electric heat tracing technology plays an indispensable role in food processing equipment. This paper will introduce the application of electric heat tracing in food processing equipment in detail.

With the increasing awareness of environmental protection and rising energy prices, traditional heating methods have been unable to meet the needs of the modern food processing industry. Therefore, the development of an efficient, safe and environmentally friendly heating method has become an urgent need for the food processing equipment manufacturing industry.

Principle and characteristics of electric heat tracing

Electric heat tracing is a heating method that uses electrical energy to generate heat through a resistor. The working principle is: when the current passes through the resistor, the resistor will heat up because of the resistance, and then transfer the heat to the surrounding object or medium, so as to achieve the purpose of heating.

Compared with traditional heating methods, electric heat tracing has the following obvious advantages:

1. High efficiency: The efficiency of converting electrical energy into heat energy is as high as 95%, which is much higher than the traditional combustion method.

2. Safety: electric heat tracing does not need to burn fuel, avoiding the occurrence of fire and other safety hazards.

3. Environmental protection: no waste gas, no noise, no pollution, in line with the requirements of current environmental protection policies.

4. Controllability: The temperature can be accurately controlled by adjusting the current size, which is convenient for operation and management in the production process.

Third, the application of electric heat tracing in food processing equipment

1. Electric heating wok: The use of electric heating technology can quickly heat the bottom of the pot to the set temperature and maintain a constant temperature, making the cooking process more uniform and fast, improving cooking efficiency and dish quality.

2. Electric oven: Using the principle of electric heat tracing, the electric energy is converted into heat energy and evenly distributed in the oven for baking bread, cakes and other foods. Compared with traditional gas ovens, electric ovens have better temperature control performance and higher energy efficiency.

3. Food sterilization equipment: In the process of food processing, in order to ensure the health and safety of food, it is necessary to carry out high-temperature sterilization of food. The sterilization equipment using electric heat tracing technology can heat the food to the specified sterilization temperature in a short time and maintain enough time to effectively kill bacteria and viruses in the food. At the same time, because the electric heat tracing has good temperature control performance, it can avoid destroying the nutritional composition and taste of food due to high temperature.

4. Beverage production line: In the beverage production process, the water needs to be heated and cooled. Heaters and coolers with electric heat tracing technology can adjust the temperature in real time according to the needs of the production process to ensure the stability of the quality and taste of the beverage. In addition, the electric heat tracing equipment also has the advantages of small footprint and convenient installation, which is conducive to improving the overall efficiency of the production line.

To sum up, electric heat tracing has a wide range of application prospects and huge market potential in food processing equipment. With the continuous progress and innovation of science and technology, it is believed that more efficient, safe and environmentally friendly electric heating equipment will come out in the future, bringing a better tomorrow for the food processing industry.
