Embodiment 1
[0020] A method for producing apple crisps by a differential pressure puffing process, using fresh apples as raw material, the steps are as follows:
[0021] (1) Selection: Select ripe apples with a smooth surface, no rot, no damage from diseases and insect pests;
[0022] (2) Cleaning: Clean the selected raw material fruits with detergent first, and then rinse them with clean water;
[0023] (3) Peeling: Peel the washed fruit with a peeling machine;
[0024] (4) Slicing: Cut the peeled fruit into slices of 2.5mm to 3mm;
[0025] (5) Color protection: Immediately put the sliced apples into the sulfur-free color protection solution and soak for 15 minutes. %;
[0026] (6) Differential pressure puffing: Drain the soaked apple slices and lay them flat in the differential pressure puffing machine so that the material is at 85°C and the pressure difference is 0.35MPa. The boiling point is rapidly reduced by vacuuming, resulting in a vacuum state The superheated water flas...

[0030] A method for producing apple crisps by a differential pressure puffing process, using fresh apples as raw material, the steps are as follows:
[0031] (1) Selection: Select ripe apples with a smooth surface, no rot, no damage from diseases and insect pests;
[0032] (2) Cleaning: Clean the selected raw material fruits with detergent first, and then rinse them with clean water;
[0033] (3) Peeling: Peel the washed fruit with a peeling machine;
[0034] (4) Slicing: Cut the peeled fruit into slices of 2.5mm to 3mm;
[0035] (5) Color protection: Immediately put the sliced apples into the sulfur-free color protection solution and soak for 15 minutes. %;
[0036] (6) Differential pressure puffing: Drain the soaked apple slices and lay them flat in the differential pressure puffing machine so that the material is at 80°C and the pressure difference is 0.3MPa. The boiling point is rapidly reduced by vacuuming to cause a vacuum state The superheated water flashes in...
Embodiment 3
[0039] A method for producing apple crisps by a differential pressure puffing process, using fresh apples as raw material, is carried out as follows:
[0040] (1) Selection: Select ripe apples with a smooth surface, no rot, no damage from diseases and insect pests;
[0041] (2) Cleaning: Clean the selected raw material fruits with detergent first, and then rinse them with clean water;
[0042] (3) Peeling: Peel the washed fruit with a peeling machine;
[0043] (4) Slicing: Cut the peeled fruit into slices of 2.5mm to 3mm;
[0044] (5) Color protection: Immediately put the sliced apples into the sulfur-free color protection solution and soak for 15 minutes. %;
[0045] (6) Differential pressure puffing: Drain the soaked apple slices and lay them flat in the differential pressure puffing machine so that the material is at 90°C and the pressure difference is 0.3MPa. The boiling point is rapidly reduced by vacuuming, resulting in a vacuum state The superheated water flas...
