Food conveyor belts are a kind of conveying equipment widely used in the food industry. Many foods need the support of high-temperature-resistant conveyor belts during transportation, but many people may wonder why they must be used. This article will analyze this in detail.
- The need to extend the shelf life of food
Food contains certain nutrients and moisture, which are the basic conditions for the reproduction of microorganisms such as bacteria, molds and yeast. When the storage temperature of food is suitable for the growth of microorganisms, the food is prone to spoilage. Through aseptic packaging, high temperature sterilization or refrigeration and other treatments, food spoilage can be effectively prevented, thereby extending its shelf life.
In these treatments, high temperature resistant conveyor belts play a key role. Suppose the conveyor belt cannot withstand high temperature treatment. In that case, it will not only shorten the service life of the conveyor belt, but also may affect the continuity and efficiency of food production.
- Convenient food circulation and cold chain development
For example, dumplings, glutinous rice balls, seafood and other foods have a short storage time at room temperature and their circulation is restricted. However, the rise of frozen foods has enabled these foods to be sold more widely, which is inseparable from the support of new packaging technologies.
Packaging not only protects food, but also enhances the aesthetics and competitiveness of products. Beautifully designed packaging is more likely to attract consumers and promote sales. However, in these processing processes, the use of high-temperature conveyor belts is particularly important:
Freezing process requirements: Food is frozen and stored after high-temperature sterilization, which puts higher requirements on the temperature adaptability of the conveyor belt.
Packaging stability: High-temperature conveyor belts can ensure stable operation under high temperature and high load conditions and improve production efficiency.
Warm reminder: Although packaging brings convenience to the food industry, excessive packaging should be avoided to reduce resource waste and environmental pollution.
- Material and temperature range of high-temperature resistant food conveyor belts
Their materials determine the performance of high-temperature conveyor belts. The following are common high-temperature resistant conveyor belt materials and their temperature ranges:
Ordinary belts: suitable for -15℃ to 100℃, distinguishing between normal temperature and instantaneous high temperature.
Silicone material: good temperature resistance, can withstand more than 200℃.
Teflon material: high-performance high-temperature resistant material, can withstand temperatures up to 250℃, and is the preferred material for high-temperature resistant conveyor belts.
When selecting a conveyor belt, the appropriate material should be selected according to the temperature requirements of the production environment to ensure the performance and durability of the conveyor belt.
Precautions for using high-temperature resistant food conveyor belts
When using high-temperature resistant food conveyor belts, the following issues need to be noted:
Control the load
Ensure that the weight of the conveyed material does not exceed the maximum carrying capacity of the conveyor belt to avoid breakage due to overloading. At the same time, the type of conveyed material should be in line with the use range of the conveyor belt to prevent wear or damage.
Standard operation
The operator and staff need to cooperate closely when the conveyor belt is running. Suppose the conveyor belt needs to be adjusted. In that case, the staff must be notified in advance and coordinated to avoid accidents caused by blind operation.
Safe operation
No person shall interfere with the conveyor belt’s operation. In case of emergency, the switch should be used to stop the conveyor belt in time to ensure that the problem is properly handled.
Through the above analysis, the application of high-temperature resistant food conveyor belts is not only a necessary choice for food processing and transportation, but also an important guarantee for improving food quality and production efficiency. Selecting the appropriate conveyor belt material according to production needs and complying with operating specifications can significantly extend the service life of the conveyor belt and help the sustainable development of the food industry.
