Lyophilization or freeze drying is a process in which water is removed from a product after it is frozen and placed under a vacuum, allowing the ice to change directly from solid to vapor without passing through a liquid phase. The process consists of three separate, unique, and interdependent processes; freezing, primary drying (sublimation), and secondary drying (desorption).

1:What is the working principle of food freeze dryer?
Vacuum freeze dryer machine refers to a process in which solid materials are directly sublimated into a gaseous state for drying under vacuum conditions without passing through the liquid phase.
2:Will food retain its original form and nutrients after freeze-drying?
During the freeze-drying process, the solvent directly sublimates from the solid state to the gaseous state, so the original chemical structure and form of the solute will not be destroyed.Lyophilization is the safest drying method with the least impact on the properties of the material being dried.
3:What models of small food freeze dryers can you choose?
Our company can provide a variety of models of products to meet your different freeze-drying needs.Such as LFD-1,LFD-4,LFD-6,LFD-8,LFD-9,LFD-10,LFD-15 and accept customer customization.
4:What products can be processed by a food freeze dryer?
The types of food that the food freeze dryer can process include fruits, vegetables, meat and milk, as well as tea and so on.
5:What are the requirements for the working environment of a freeze dryer?
The freeze dryer needs to operate in a suitable environment,temperatures above 5°C and below 30°C and at suitable humidity(use ventilation equipment such as dehumidifier,dehumidifier or directly open windows for ventilation).
