freeze dry machine principle:
In the vacuum state, the principle of ice crystals is used to directly sublimate the moisture in the pre-frozen materials into a gaseous state, so that the materials are dried and the freeze-dried food is quickly frozen and dehydrated in the vacuum ice state, preserving the original color, aroma and taste. , nutritional content and original material appearance and good rehydration properties, and does not contain any additives, making it an ideal hygienic food. Reasonable structure, easy maintenance and low cost. Fully automatic control, easy to operate, with the function of self-tuning the freeze-drying curve, display and recording of various parameters, and the working status is clear at a glance.
