Working Principle

The Steam Tunnel Dehydrator relies on hot air circulation and steam-assisted heating. Food items are loaded onto a conveyor belt and transported through a sealed tunnel with multiple temperature zones. Inside, steam heats the air, which is then circulated by blowers to create a high-temperature environment. As products move through the tunnel, moisture evaporates and is expelled via exhaust systems. An automated control system precisely manages temperature, humidity, and dwell time, ensuring consistent dehydration while minimizing nutrient loss.

Features

Continuous Processing:

Enables non-stop operation to enhance production efficiency for large-scale needs.

Uniform Dehydration:

Optimized hot air distribution and zone control ensure even moisture removal for products with uniform quality.

Energy Efficiency:

A steam recovery system and insulated design reduce energy consumption and lower operating costs.

Hygienic Design:

Smooth surfaces and easy-to-clean structures meet food safety standards, allowing for thorough cleaning.

Intelligent Control:

A PLC-based control system allows precise parameter settings and real-time monitoring, supporting customized drying curves for different materials.

Robust Construction:

Built with high-quality materials like stainless steel for durability and long-term reliability.

Technical Highlights

Key technologies include steam heating technology (efficient heat transfer through steam-air interaction), hot air recirculation systems (reusing hot air to save energy), and advanced insulation materials (minimizing heat loss).

The PLC control system integrates temperature sensors, humidity monitors, and variable frequency drives (VFDs) for the conveyor to enable precise process management.

Optional features such as humidity control units or cooling sections can be added to accommodate specific drying requirements, ensuring the technology adapts to different product characteristics.

Application Fields

It is widely used in the food industry for dehydrating various products:

Fruits: Such as apricots, bananas, mangoes, and apples for dried fruit production.

Vegetables: Like carrots, onions, spinach, and mushrooms for dehydrated vegetables used in instant meals, soups, or snacks.

Meat Products: Including beef, pork, and chicken for jerky or meat-based seasonings.

Seasonings & Powders: Instant noodle seasonings, spice blends, and vegetable powders for food processing.

Herbs & Spices: Drying herbs (e.g., basil, oregano) and spices to retain aroma and potency.
It is also applied in drying pet food, algae (e.g., spirulina), and other heat-sensitive food materials, making it a versatile tool for extending product shelf life and improving quality.
