Working Principle

The dehydrator operates via continuous-flow tunnel technology. Raw materials enter the sealed tunnel on a motorized conveyor and pass through heating zones, where electric heaters (infrared or resistance-type) generate hot air. A powerful ventilation fan system forces this hot air to circulate around the product in a controlled manner, efficiently evaporating moisture. The moist air is then expelled through an exhaust mechanism, maintaining optimal humidity levels. Drying parameters (time, temperature) are adjustable via the control panel to suit different products, enabling customized dehydration.

Features

Continuous High-Efficiency:

Enables non-stop batch-free drying, perfect for mass production.

Precise Temperature Control:

Advanced PID thermostats ensure uniform heat distribution, minimizing hot spots and maximizing product consistency.

Hygienic & Durable:

Constructed from food-grade stainless steel, with a sealed tunnel design to prevent contamination; meets FDA/ISO hygiene requirements.

Automated Operation:

Integrated PLC or touch-screen controls simplify setup for temperature, air speed, and conveyor pace, reducing manual labor.

Energy-Saving Design:

Thick insulation (e.g., rock wool) and optimized air circulation minimize heat loss, lowering utility bills.

Technical Highlights

Heating Technology:

Uses efficient electric heating elements (infrared or PTC) for rapid, stable heat generation.

Air Flow System:

A high-capacity fan ensures uniform air distribution across multi-layer conveyors, supporting even drying.

Control System:

A PLC or intelligent controller monitors and adjusts key parameters in real-time, with data logging capabilities for quality追溯.

Structural Materials:

The main body is made of corrosion-resistant stainless steel; insulation uses high-temperature rock wool; conveyors are available in mesh belt or tray types.
