Small fruit and vegetable freeze-drying machine, also known as small food freeze-drying machine, is a food grade freeze-drying equipment for the deep processing of durian, strawberry, banana, apple, pineapple, pitaya, okra, mushroom and other fruits and vegetables. Freeze dried fruit uses the vacuum freeze-drying method of the freeze dryer to freeze the water in the fruit in advance, and then sublimate the frozen water in the fruit in a vacuum environment to obtain the freeze-dried fruit. In short, extract the water in the fruit at low temperature to retain its original nutrition. The freeze-drying process of vegetables can be divided into three stages: pretreatment, vacuum freeze-drying and post-treatment; The technological process of vegetable freeze-drying is as follows: fruit and vegetable raw materials → picking and sorting → cleaning → shaping and processing → loading → vacuum freeze-drying → packaging → finished products.

What are the advantages and characteristics of vegetable and fruit jelly dryer?

1. Pre freezing and drying are completed in situ. The freeze-drying process is automatic and easy to operate.

2. Circulating medium is distributed in the plate layer, and the temperature can be adjusted. The temperature difference is ≤ 1 ℃, and the refrigeration and heating effect is more uniform.

3. Touch screen operation, PLC control system, real-time monitoring of equipment operation.

4. R404A environment-friendly refrigeration and high-efficiency piston / screw compressor are adopted; It can be connected to the computer for remote control and storage of freeze-drying curve.
