Apple drying process:
Raw material→washing→peeling→slicing→soaking in liquid medicine→drying→selection→packaging.



Pre-processing of apple slices:
Selection of raw materials: Choose the fruits with dense flesh, high sugar content, thin skin and thick flesh, and fully mature fruits, and remove rotten and disabled fruits.
Raw material processing: In order to remove the pesticides on the peel, the fruit is washed with running water. Peel the skin and core by hand or machine, cut into 7-8 mm thick discs, and then put them in the salt water.
Color protection: Put the cut apple slices in a solution of 3% to 5% salt water to protect the color to avoid oxidation and browning. If the fruit pieces are floating on the potion, they should be pressed with a cover curtain weight on the fruit pieces to ensure that the fruit pieces are completely immersed in the potion.
 
Apple Drying processing of apple slices:
1. Drying:
①Drying room temperature: 60～80℃.
②Drying time: 5 to 10 hours.
③ Dehumidification: Always dehumidify during the drying process.
④During the drying process, it is necessary to prevent the temperature from fluctuating from high to low.
2. Selection of slices: The dried apples should be manually selected and trimmed.
①Trimming: Trim off the remaining seed nests, peels, mechanical scars, spots, pests and diseases on the fruit slices.
②Selection: Remove the water slices (non-dried slices), paste slices, fragments and dirty slices from the fruit slices, and remove impurities.
