Batch-Type Hot Air Circulation Tray Vegetable Dryer Machine

Premium Hot-Air Circulation Batch-Type Tray Food Dryer for Fruits & Vegetables

The hot air circulation tray vegetable and fruit dryers utilize enclosed convection systems to achieve high thermal efficiency (up to 50%) for uniform dehydration. We supply the dryer machine range, from compact residential units (1 trolley, 48 trays) to large-scale industrial ovens with more trolleys(up to 5 trolleys, 240 trays). The full body of the dryers is made of 304 Stainless Steel. These models of vegetable dryers offer professional-grade features in a more compact footprint suitable for small businesses.

When drying high-value fruits (like mangoes, apples, and berries) or robust vegetables (like carrots, onions, and sweet potatoes), precise temperature control and uniform airflow are critical. This food drying machine utilizes forced, high-volume horizontal airflow to guarantee every single piece of fruit or vegetable dries evenly. Our Hot-Air Circulation Tray Food Dryer is engineered to deliver consistent, high-quality dehydration, ensuring your products retain their vibrant color, vital nutrients, and optimal flavor profile—batch after batch. The Industry Standard for Batch Dehydration of Fruits & Vegetables.

This food dryer machine is highly versatile. By simply adjusting the temperature and time on the control panel, you can process a massive variety of agricultural goods.

• Fruit Snacks: Apple rings, mango slices, dried bananas, pineapple chunks, raisins, and fruit leathers/roll-ups.
• Dehydrated Vegetables: Garlic flakes, onion powder prep, dried carrots, cabbage, mushrooms, chili peppers, and sweet potato fries.
• Herbs & Spices: Basil, parsley, mint, ginger slices, turmeric roots, and tea leaves.
• Nuts & Seeds: Roasting or drying pumpkin seeds, sunflower seeds, walnuts, and macadamias.

Fruits and vegetables naturally have a very high water content (often 80-90%). To dry them properly without cooking them, you need a constant exchange of dry heat and moisture removal.

• Heat Generation: The internal heating elements (electric, steam, or gas) warm the air inside the chamber.
• Forced Circulation: Top-mounted, high-temperature Axial Fan Motors force the hot air down through the side air ducts. The air is then blown horizontally across and between every single layer of trays on the trolley.
• Moisture Extraction: As the hot air absorbs the moisture from the wet fruit or vegetables, the air becomes humid. The top-mounted Moisture Barrier / Exhaust Vent actively expels this wet air out of the machine, while drawing in a controlled amount of fresh air.
• Continuous Cycle: This closed-loop circulation process repeats continuously, drastically speeding up drying times while saving energy.

• 100% Food-Grade Stainless Steel Construction. The entire cabinet (interior and exterior), the baking pans (trays), and the trolleys are constructed from high-quality SUS304 stainless steel. It is fully welded with smooth corners, ensuring it is anti-corrosive, easy to wash down, and strictly meets GMP, HACCP, and FDA hygiene standards.
• Heavy-Duty Wheeled Trolleys (Carts). Your operators load the trays onto the stainless steel cart outside the machine. Then simply roll the cart into the chamber. Save time and allow for rapid batch changeovers.
• Precision Electric Control Cabinet. The side-mounted control panel is the brain of the operation. It features intelligent PID temperature controllers, timers, and fan switches. You can set the exact temperature required for your specific produce (e.g., a gentle 55°C for strawberries, or a robust 75°C for garlic flakes) and let the machine run autonomously.
• Thick Polyurethane/Rock Wool Insulation. The walls and double-doors feature ultra-thick thermal insulation and high-temperature silicone rubber door seals (with heavy-duty Door Switches/Latches). This traps the heat inside the drying room—saving massive amounts of electricity—and keeps the outside of the machine cool and safe for workers to touch.
• Customizable Backing Pans (Trays). We provide high-quality stainless steel trays tailored to your product. For standard sliced vegetables, we use wire-mesh or perforated punched-hole trays to allow maximum airflow from the bottom up, ensuring a perfectly even dry.

When processing premium agricultural commodities—where the final product is sold in boutique grocery stores or used in high-end culinary applications—aesthetics and flavor are everything. You cannot afford burnt edges, case-hardening (wet inside, dry outside), or color degradation.

Key High-Value Produce Applications:

• Exotic Premium Fruits: Mango slices, dragon fruit, kiwi, figs, and persimmons. The forced-air circulation ensures these high-sugar fruits dry evenly, maintaining a vibrant, appetizing color and a pleasant, chewy texture without caramelizing the natural sugars.
• High-End Spices & Aromatics: Vanilla pods, saffron, cardamom, and premium chili threads. These commodities rely entirely on their volatile aroma compounds. The dryer’s precise PID controller allows for “low and slow” drying (e.g., 35°C – 45°C), locking in the expensive essential oils.
• Gourmet Mushrooms: Porcini, Morel, and Shiitake mushrooms. Fast moisture removal is required to stop enzymatic browning, but gentle airflow is needed to keep the fragile mushroom caps intact.
• Superfood Powders & Teas: Processing matcha, moringa leaves, or beetroot for high-end smoothie powders. The rapid, even dehydration prevents the loss of heat-sensitive antioxidants (like Vitamin C) and preserves the bright green or deep red pigments.

Zero Product Waste: Because the airflow is engineered to reach the top, middle, and bottom trays equally, you do not need to pause the machine to “rotate the trays.” Every batch comes out with uniform moisture content.
Durability: With no complex, delicate moving parts (like continuous belts) and a fully stainless steel body, this machine is a “workhorse.” With basic cleaning and fan maintenance, it is designed to run 24/7 for decades.
Scalability: Whether you need a small single-door/single-trolley unit for an artisanal fruit-leather brand or a massive 4-door/8-trolley unit for an industrial vegetable farm, the modular design scales to fit your exact capacity needs.
