Ceramic fiber products can indeed be used in food processing industries, but with specific considerations. They are often used for their heat resistance and thermal insulation properties in applications such as ovens, kilns, and other high-temperature equipment. However, it's crucial to ensure that the ceramic fibers do not come into direct contact with food products to avoid contamination. The use of ceramic fiber products must comply with food safety regulations, and they should be properly contained to prevent the release of fibers that could potentially contaminate food.
