Embodiment 1
[0035] A method for microwave vacuum drying of Chinese wolfberry, comprising the following steps:
[0036] (1) Material selection: select bright red color, no mildew disease, no damaged fresh fruit wolfberry.
[0037] (2) Grading: The wolfberry automatic grading device is used to trigger the vibration of the hopper through the pulse electromagnet to complete the automatic transportation of the wolfberry, and the jet separation device completes the automatic classification of the wolfberry. Fresh goji berries with the same size and maturity were selected as the same grade.
[0038] (3) Removal of the fruit: remove the remaining fruit in the fresh fruit.
[0039] (4) Sterilization and enzyme elimination: Pour the fresh fruit of wolfberry of the same level into the high-voltage pulse electric field treatment chamber, and under the conditions of high-voltage pulse electric field intensity 2kV / cm and pulse number 50, use the conductance of high-pressure water mist under the high-v...
