Defoamer FAQ Section (Continued)
Q: Can defoamer be used in food processing applications?
A: We offer food-grade defoamer products that comply with FDA 21 CFR 173.340 and other international food safety standards. These products are specially formulated for use in food processing, fermentation, and other food-related applications.
Q: What's the difference between antifoam and defoamer?
A: While often used interchangeably, antifoams prevent foam formation, while defoamers eliminate existing foam. Our products can be formulated to perform both functions depending on application requirements.
Q: How should defoamer be stored?
A: Store defoamer in a cool, dry place away from direct sunlight. Keep containers tightly sealed when not in use. For emulsion-type defoamers, avoid freezing as it may damage the product's effectiveness.
Application Guidelines
For optimal defoamer performance:
- Determine the foam formation point in your process
- Select the appropriate defoamer type based on system conditions
- Add defoamer at the foam formation point for maximum efficiency
- Monitor foam levels and adjust dosage as needed
- Maintain proper mixing to ensure uniform distribution
