How to ensure that PTFE conveyor belts will not react chemically?

When using PTFE conveyor belts, measures to ensure that the conveyor belts will not react chemically when exposed to different food additives and cleaning agents, which will affect the safety and quality of food include the following:

1. Choose the right PTFE conveyor belt
Material purity: Choose high-purity PTFE materials to reduce possible chemical reactions caused by impurities.
Certification and compliance: Ensure that the conveyor belts meet the relevant standards and certifications for food contact materials, such as the FDA (US Food and Drug Administration) and the EU's EC 1935/2004.

2. Understand the chemical properties of food additives and cleaning agents
Chemical compatibility testing: Conduct chemical compatibility tests on PTFE conveyor belts for food additives and cleaning agents to ensure that they will not have adverse reactions during actual use.
Durability testing: Conduct long-term exposure tests to observe the performance changes of the conveyor belts after contact with these substances.

3. Regular cleaning and maintenance
Cleaning procedures: Establish strict cleaning procedures and use appropriate cleaning agents and methods to ensure the cleanliness and sterility of the conveyor belts.
Maintenance plan: Regularly inspect and maintain the conveyor belt to detect and deal with possible damage or contamination in a timely manner.

4. Monitoring and recording
Use monitoring system: Install a monitoring system to monitor the status of the conveyor belt in real time and detect any possible abnormalities.
Record and track: Record all cleaning and maintenance activities and establish detailed record files for traceability and analysis.

5. Staff training
Operational specification training: Train operators to ensure that they understand how to properly use and maintain PTFE conveyor belts.
Emergency response training: Train employees to deal with emergencies, especially when chemical reactions or contamination occur.
