동결건조 과일·채소 칩 식품 가공 기계

I. 설명
Freeze-dried fruit and vegetable chips are a crispy snack made from fresh produce. They go through washing, slicing, quick-freezing, and vacuum freeze-drying. The drying process happens at low temperature. The structure of the material stays intact. Color, shape, flavor, and nutrition are very well preserved. They rehydrate well. This is a representative product in the premium healthy snack market.

This production line is a complete set of equipment. It includes washing, slicing, quick-freezing, vacuum freeze-drying, and packaging units. The line is designed to food hygiene standards. Materials move smoothly between steps.

It is sliced into even pieces. The slices are placed on trays.
Then they go into a quick-freezing unit. They are frozen at -35°C to -40°C.
After freezing, they enter a vacuum freeze-dryer. Under vacuum, the temperature is raised gradually. Ice crystals inside the material turn directly into vapor. This vapor is removed. The material is dried to a moisture content below 3%-5%.
After coming out, the product is packed immediately. Nitrogen flushing or vacuum packaging is used. This prevents moisture absorption.
