Apple Chip Production and Processing Technology
First, the raw material cleaning: with 1% sodium hydroxide and 0.1-0.2% of the detergent mixture, soaked in warm water at 40 °C for 10 minutes, and then remove and wash, fully wash away the detergent on the surface of the fruit.
Second, slice: remove the pests and rot parts, go to buds, stalks, slice with a slicer, thickness of 5 mm, uniform thickness.
Third, color protection: Weigh 400 grams of salt, 40 grams of citric acid dissolved in 40 kilograms of water, pay attention to the full dissolution of citric acid and salt, and in time to cut fruit slices immersed in color protection solution.
4. Fix the green: Add 4 to 5 times the weight of water in the killing pot. After boiling, add the fruit pieces for 2-6 minutes.

Each time the fruit pieces are soaked, the sugar content of the syrup will be reduced. It is necessary to add high-intensity syrup to ensure that the sugar content of each syrup is 30%.
VI. Vacuum frying: Fill the fryer with oil, raise the oil temperature to 100°C, put the frying basket with the fruit pieces drained in the frying equipment, close the material door, start the vacuum pump, cooling water and With the oiling device, when the vacuum pump reaches -0.095 MPa, put the frying basket under the oil surface, fry until the liquid level is stable, lift the frying basket from the oil, and continue evacuating for 2 minutes. Close the valve, stop the vacuum pump, break the vacuum, remove the fry basket, and place it in the deoiler.
7. Deoiling: Start the degreasing machine and vacuum pump, take the time of -0.09 MPa, deoil for 3 minutes.
8. Bagging: Pour apple chips into the operating table, promptly open the sticky pieces, and pick out pieces that have not been thoroughly blown and stained. After the fruit pieces are allowed to cool to room temperature, they are weighed and bagged. Heat sealing machine can be sealed.
