Fruit Vacuum Freeze Drying Machine
Fruit vacuum freeze drying machine is suitable for freeze drying plant-based ingredients, including fruits, vegetables, cereals and more..Freeze dried fruit machine is mainly based on vacuum technology, freezing technology, drying technology and aseptic technology. By freeze-drying fruits and vegetables and other materials.
Fresh plant-based ingredients can be challenging to store for long periods of time due to their high moisture content. Therefore, drying such ingredients can make them easier to handle, easier to transport and easier to store for long periods of time.The oxidative, high temperature and mechanical damage effects of conventional drying and dewatering methods often affect the stability and retention of valuable bioactive components in plant-based ingredients. For example, phenolic compounds may be susceptible to enzymatic degradation due to polyphenol oxidase activity. In addition, carotenoids are highly unsaturated, making them susceptible to degradation by oxidative and thermal processes. Moreover, the loss of vitamin C and carotenoids is particularly affected by the temperature and moisture content during the drying process. Phenolic compounds, vitamin C and carotenoids are typical bioactive nutrients in plant-based ingredients;
Fruit and vegetable vacuum dryer is divided into experimental, medium and large. In food freeze dryers of the KFD seriesKFD-1, KFD-2, KFD-5 are for pilot use, KFD-10, KFD-20, KFD-30, KFD-50 are medium-sized freeze-dryers, and KFD-100, KFD-200 are large scale freeze-dryers, which are suitable for batch production of food factories.
