Vacuum pulsation drying technology is a new type of drying technology, which uses the alternating changes of vacuum atmospheric pressure pulsation in the drying chamber to change the microstructure of the material and promote the migration and diffusion of moisture inside the material; At the same time, the vacuum low oxygen environment effectively inhibits the oxidation browning of the material during the drying process, while effectively improving the drying efficiency and maximizing the preservation of the original color and nutritional content of the material.

Vacuum pulsation drying technology solves the problem of fruitvegetablesnatural dryingAnd adopt other forms of hot airThe problems of long drying time, severe loss of thermosensitive nutrients, and color deterioration in drying exist, especially in solving the chemical problems caused by the use of drying agents to promote the drying of goji berries, grapes, etc. with wax layer covering the surfacepreparationThe problem of excessive sulfur content caused by residual and sulfur fumigation treatment provides a comprehensive improvement for the overall level of China's fruit and vegetable drying industryTechnology and TheorySupport.

Drying using vacuum pulsation technology can lock in the nutrients of fresh fruits in the first time, with a smooth shape, rosy color, soft taste, and unique flavor,Goji berries, grapes, and red date crisps basically maintain the original fruit flavor and color, with high rehydration rate. After drying, the surface cells of the material have a porous structure, which is conducive to the dissolution and utilization of effective ingredients during deep processing or direct consumption.Has high economic value.

The vacuum pulsation dryer integrates contact and radiation heat transfer technology, vacuum pulsation technology, automatic monitoring technology for drying process, color touch screen program control technology, etc. It can dynamically optimize and control the drying process in real time according to material characteristics, with high degree of drying automation, short drying time, and good product quality.Compared to other technologies, it can save energy consumption70%.
