Food preservation has always been the focus of people's attention, and with the continuous development of science and technology, various preservation technologies are also emerging. Among them, as a new type of preservation technology, heat tracing has been widely used in the field of food preservation. The following will introduce the application of heat tracing in food preservation.
Heat tracingIt is a flat heating band composed of a conductive polymer material, two parallel metal wires and an insulating sheath. It can heat the object that needs to be heated by converting electrical energy into heat energy. Heat tracing has the advantages of fast heating speed, uniform temperature, safety and reliability, so it is widely used in various fields.
Heat tracing is used in the way food is preserved
1.Heat to keep fresh.
In food preservation, heating preservation is a common way. By heating food by using heat tracing, the shelf life of food can be extended. For example, in dairy production, heat tracing can be used to heat milk to kill bacteria in the milk and extend its shelf life.
2.Defrost and keep fresh.
In the process of thawing frozen food, problems such as blood and water loss and meat quality aging often occur, which affect the taste and quality of food. The use of heat tracing for defrosting can make food thaw more evenly, reduce blood and water loss, and maintain the taste and quality of food.
3.Keep warm and fresh.
In the process of food transportation, in order to ensure the temperature of the food, it is necessary to use thermal insulation equipment. The heat trace can be used as a thermal insulation device to keep food warm. For example, during the transport of frozen food, the carriage can be heated with a heat trace to maintain the temperature of the food.
Advantages of heat tracing in food preservation:
Heat tracing can be customized as needed to meet the preservation needs of different food products.
The heating speed of the heat trace is fast, and the set temperature can be quickly reached, which improves the preservation efficiency of food.
The temperature of the heat trace is uniform, which can avoid the problem of local overheating or overcooling of food.
Heat tracing is safe and reliable and will not contaminate food.
In general, as a new type of preservation technology, heat tracing has the advantages of fast heating speed, uniform temperature, safety and reliability, and can be widely used in the field of food preservation. In the future development, heat tracing will receive more and more attention and application.
