Frequently Asked Questions

VF vacuum frying machine uses low-temperature vacuum frying technology, frying under negative pressure environment (usually 60-100kPa). Under vacuum, the boiling point of water decreases (about 80-90°C), allowing frying at lower temperatures, reducing oil oxidation and nutrient loss while maintaining natural color and texture.

FD freeze-drying equipment has the following advantages: 1. Preserves original shape, color and nutritional content; 2. Low moisture content (usually <5%), suitable for long-term storage; 3. Good rehydration ability, quickly restores to original state; 4. No preservatives needed; 5. Suitable for drying heat-sensitive materials.

Recommended maintenance cycle: Daily maintenance: clean equipment exterior and interior after each use; Weekly maintenance: check vacuum pump oil level, clean filters; Monthly maintenance: inspect seal wear, calibrate temperature sensors; Annual maintenance: comprehensive overhaul, replace consumable parts, check electrical systems.
