The apple is a pome that is from the Latin word for apple, a fruit with a papery central cavity encompassing the seeds. Pomes are members of the family Rosaceae (rose) family that also includes pear, crabapple, and quince.

Dried Apple Chips in Food Processing Factory

Generally, the automatic production line for manufacturing dried apple chips is set in a food factory, which includes washing, peeling, coring, slicing, drying, expanding and packing. The apples are washed within the washing tunnel at the first, and go on next step where the clean apples are peeled and cored by apple peeling and coring machine, then fished apples are sliced and prepared to dry by drying machine. We’ll introduce 2 effective drying equipment that is utilized widely in a food factory as following: hot air circulation drying oven and vacuum microwave drying machine.

Dried apple chips by hot air circulation drying ovens

The drying process is carried out in a conventional cabinet drier that adopts hot air circulation drying with high temperature resistant axial flow fan and automatic temperature management system. The drying is the method that the apple slices are heated in the trays with hot air circle, the wet moisture removed from apple slices is exhausted outside at the same time. And the apple slices are dried at 105°C for about 120 min usually. Apple slices in the oven are often dried uniformly due to the forced ventilation and adjustable air distributor. Then customers will enjoy the delicious finished apple chips from the market when the dried apple chips are packaged well.

Dried apple chips by vacuum microwave drying machine

Besides that, to enhance the quality of the dried products and the method efficiency, microwave vacuum drying can be used. Microwave drying is utilized to prepare apple chips with a puffy and crispy texture. Vacuum microwave dehydration offers an alternate way to improve the quality of dehydrated apples. Place the apple slices into the machine, and microwaves penetrate to the inside of the apple slices causing water to boil in the apple slices. This leads to a greatly increased vapor pressure differential between the center and the surface of the apple slices, permitting fast transfer of moisture out of the slices. The moisture is removed from the drying chamber by the water-ring pump that maintains the vacuum. Therefore, apple chips can be dried quickly without exposure to high temperatures, and color, flavor, and nutrient properties of apple chips is vastly preserved.
