Embodiment Construction

[0028] The manufacture method of microwave vacuum freeze-drying lemon slice of the present invention is as follows:

[0029] 1. Fresh lemon fruit is graded and selected, and the fruit with a transverse diameter of 50-65 is selected;

[0030] 2. Send it to a constant temperature warehouse sterilized by ozone at a constant temperature of 10°C-13.5°C for storage.

[0031] 3. Ozone degrades pesticide residues, each time for 30 minutes, and the ozone concentration is above 3ppm. Thereby achieving 99.9% sterilization and extending the processing period for more than three months.

[0032] 4. After degrading the lemon fruit with pesticide residues, after cutting off the head and tail, carry out sterilization and cleaning with high-concentration (above 0.8ppm) ozone water.

[0033] 5. Directional slices by slicer. The key to directional slices is to orient the lemon fruit when slicing. Through directional slicing, the whole fruit can be sliced ​​horizontally, the pattern of the s...
