Continuous Tray Dryer
Features a vertical structure with multiple stationary, hollow, circular heating trays and rotating rakes for agitation; relies primarily on heat conduction rather than complex hot-air systems.
Offers high thermal efficiency, low energy consumption, and a compact footprint; material movement is gentle, minimizing particle breakage.
Temperature can be precisely controlled by adjusting heating medium parameters, making it suitable for heat-sensitive food materials; low exhaust emissions simplify environmental compliance.
Vibrating Fluidized Bed Dryer
Composed of a vibration generation unit (electromagnetic, mechanical, or pneumatic drive), a gas distribution plate, and a fluidization chamber.
Vibration intensity is adjustable, ensuring uniform material dispersion without clumping; product-contact parts can be treated with food-grade, corrosion-resistant coatings.
Suitable for various food ingredients such as grains, legumes, and seasonings; offers high drying uniformity and supports continuous, large-scale production.
Vacuum Freeze Dryer
Core components include a pre-freezing system, vacuum chamber, heating system, and vapor condenser; moisture sublimation occurs in a low-temperature vacuum environment.
Maximally preserves the food's original flavor, nutritional content, and physical structure; ideal for processing high-end fresh produce and instant food products.
Available in laboratory, semi-continuous, and continuous models to meet varying production scale requirements.
Mesh Belt Dryer
Consists of a stainless steel conveyor mesh belt, independently controlled drying zones, and a hot-air circulation system; available in single-layer or multi-layer configurations.
Temperature and airflow velocity can be adjusted independently for each drying zone; material moves forward at a constant speed on the belt, avoiding violent agitation and minimizing breakage.
Suitable for the continuous drying of flake, strip, or granular food products, such as dehydrated vegetables and grains.
