Onion, Garlic & Vegetables Dryer
Vegetable Tray Dryer (Hot Air Cabinet)
Industrial Vegetable Tray Dryer
Vegetable Tray Dryer (Hot Air Cabinet) is one of the most widely used machines for dehydrating onions, garlic, ginger, leafy vegetables, herbs, and other agricultural products. Available in capacities ranging from 24 to 220 trays, these dryers are classified according to tray quantity and heating source, including Electric, Steam, and Gas heating systems for commercial and industrial food processing.

Design Variations
GMP Model
Manufactured entirely from SS 304 or SS 316 stainless steel with mirror-polished interiors and rounded corners to eliminate bacterial accumulation while meeting food and pharmaceutical hygiene standards.
Standard Model
Features a powder-coated mild steel exterior with SS 304 product-contact components including trays and racks, offering a cost-effective solution without compromising food safety.
Removable Trolley System
Models above 48 trays are equipped with stainless steel trolley systems for faster loading and unloading. A 96-tray machine generally includes two trolleys, while 192/220 tray models include four.
Operational Considerations
High-Efficiency Insulation
Minimum 75 mm thick Glass Wool or PUF insulation minimizes heat loss, improves thermal efficiency, and lowers electricity consumption.
Uniform Air Circulation
Commercial and industrial tray dryers use cross-flow air circulation with multiple blowers to provide equal airflow across every tray for consistent drying results.
Electric Heating
Electric heating systems are easy to install and operate, making them suitable for small and medium-scale food processing facilities.
Steam Heating
Steam-heated coils are ideal for factories with existing boiler systems and can reduce operating costs by nearly 40% compared to electric heating.
Heat Pump Technology
Modern heat pump dryers consume up to 75% less electricity while providing precise temperature control, although the initial investment is higher.
