Apple Electric Drying Oven

Edible-grade dried apples can be made using an apple electric drying oven made of stainless steel. This machine helps retain the apple’s natural nutrients and flavor while extending its shelf life.

Dried apples are a natural, healthy, and easy-to-store fruit snack. They can be eaten directly or used in baking, beverages, and food processing. With their sweet taste and rich nutrition, they are ideal snacks for children, the elderly, and people on a diet. Dried apples can also be mixed with banana chips, dried mango, and dried strawberries to make fruit mix packs, or added to oatmeal, energy bars, and meal replacement powders to enhance flavor and nutrition.

So, how are these delicious dried apples made? Let’s see how the electric drying oven works in the process.

Apple Drying Process

Selection and Cleaning

Choose fresh apples with moderate ripeness, removing any rotten or damaged parts.
Use a washing machine to remove dust and impurities from the fruit surface, preparing them for slicing and drying.

Peeling and Slicing

Peel the apples if required, or leave the skin on.
Slice the apples into 2–3 mm thickness for crispy dried apple chips, or 5–6 mm for soft dried apples, ensuring even drying.

Anti-Browning Treatment

Soak the apple slices in a 0.3% antioxidant solution (such as vitamin C or citric acid) for 3–5 minutes.
This prevents oxidation and keeps the slices bright in color.

Spreading and Loading Trays

Evenly place the treated apple slices on stainless steel trays with proper spacing to allow air circulation and heat transfer.

Drying Process

• Initial stage (50–55 °C): Remove surface moisture.
• Middle stage (55–60 °C): Accelerate dehydration.
• Final stage (60–65 °C): Set shape and color while retaining apple aroma.

Cooling and Packaging

After drying, allow the apple slices to cool naturally to room temperature before packaging.
Use aluminum bags or vacuum packaging to prevent moisture absorption and softening.

SL-C Series Apple Electric Drying Oven Drying Process

Working Principle: The SL-C series drying oven uses hot air circulation. An axial fan evenly distributes hot air into the drying chamber, ensuring all layers of the material are heated uniformly.

Temperature Settings: Initial stage: 50–55 °C to remove surface moisture. Middle to final stage: 55–65 °C for shaping and drying.

Drying Time: Typically 6–8 hours, adjustable depending on apple slice thickness and moisture content.

Control System: Automatic temperature control and timer functions keep the temperature stable, preventing local overheating or burning, and ensure evenly dried apple slices with natural color.
