The Application of Flexible Heaters in the Food Industry

Flexible heaters are also widely used in the food industry due to their unique characteristics. For the food industry, many occasions such as ingredients, processed products, and ready to eat foods require a certain temperature. Maintaining food at a safe eating temperature is one of the most important factors related to flexible heating schemes and the food industry. Cooling ready-made food can promote bacterial growth, leading to food spoilage and even disease after use.
At the same time, sometimes items must be heated to a certain extent before they can be used for various purposes and packaging processes. During the cooking process, it may be necessary to heat the ingredients without using convective heating or direct flame. For processing and packaging operations, liquid components may have to be heated to a certain temperature to prevent solidification and blockage in hoses and components when distributed to bottles, cans, and IBCs.
The Benefits of Flexible Heaters Used in the Food Industry
Polyimide/FPC flexible heaters provide temperature control for food industry applications. They can be used for food trays, heating cabinets, display cabinets, and other equipment. These flexible heaters are made of polyimide material, and etching foil elements are placed between layers using acrylic adhesive or PET adhesive. This design increases the flexibility of the heater while allowing for appropriate heat transfer between the heater and the heating surface.
Uniform and consistent heat transfer
The FPC flexible heater can reach a temperature of 392 ° F and can be used in cold environments with a low temperature threshold of -320 ° F. Due to its composition of etched foil components, this printed circuit technology provides higher heat transfer consistency. In addition, if there are different temperature ranges in the application, FPC flexible heaters allow users to distinguish power distribution. This factor helps to offset any lack of thermal consistency.
Through consistent heat transfer, food manufacturers need to be able to ensure that the entire application provides an appropriate amount of heat in the appropriate area. FPC flexible heaters can also be placed along curved surfaces or customized to present contours in different ways. FPC flexible heaters can be placed around barrels containing liquid food, food containers, and even rolling racks.
Implement constant temperature management
For the food industry, certain products must maintain a stable temperature, and the size of the heating source must be smaller. This may be a challenge. Due to the fact that smaller heating sources may concentrate excessive heat at specific locations, or due to the limited number of components allowed in heater design, insufficient heat may be generated.
FPC electric heating film, the small size of the flexible heater can reach 10X7 ″, and the thickness is only 0.007 ″. Even with these small sizes, flexible heaters can achieve power densities ranging from 2.5W/in2 to possible 50W/in2. Therefore, these small heaters can provide sufficient local heat and can manage temperature according to the requirements of the food to be heated, thereby achieving a constant temperature.
Low gas precipitation in enclosed spaces
Restaurants, hotels, resorts, bakeries, self-service restaurants, and other commercial enterprises that provide food to customers can store food in enclosed areas
