Product Description
Net-belt hot air dryer is a continuous drying equipment widely used in food, agricultural and sideline products, chemical, pharmaceutical and other industries.
1. Working Principle
Hot Air Circulation: Hot air is generated by electric heating, a steam heat exchanger, or a gas-fired hot air furnace, and forced through by a fan, creating a uniform hot air flow.
Mesh Belt Conveyor: The material is laid flat on a high-temperature-resistant mesh belt (usually made of stainless steel or polyester). The belt moves slowly through the drying chamber.
Layered Drying: The equipment is typically designed with multiple mesh belts (3-5 layers), with the material moving layer by layer from top to bottom, extending drying time and improving thermal efficiency.
Dehumidification and Exhaust: Moist and hot air is discharged through a dehumidification system, maintaining a dry environment within the chamber.
2. Main Structure
Drying Chamber: Insulated design minimizes heat loss.
Mesh Conveyor: Corrosion-resistant and high-temperature-resistant, with adjustable mesh size to suit the material.
Hot Air System: Includes a heater, fan, and air ducts (optional: top-inlet, bottom-inlet, or cross-flow).
Control System: PLC or instrumentation controls parameters such as temperature, air speed, and mesh belt speed.
Dehumidification device: Regulates humidity to prevent condensation.
3. Core Features
Continuous operation: Suitable for large-scale production with a high degree of automation.
Uniform drying: Hot air penetrates the material layer to prevent local overheating.
Energy-saving design: The multi-layer mesh belt structure recovers waste heat, reducing energy consumption by 30%-50% compared to box-type dryers.
Versatile: Suitable for processing flakes, granules, and strips (such as vegetables, fruit, feed, and medicinal herbs).
Precise temperature control: Drying temperature is typically adjustable from 50°C to 120°C.
4. Applications
Food industry: Dehydrated vegetables, dried fruits, nuts, edible fungi, etc.
Agricultural and sideline products: Feed, organic fertilizer, straw, tea, etc.
Industrial materials: Mineral powder, chemical granules, plastic slices, etc.
Pharmaceutical industry: Traditional Chinese medicine slices, medicinal extracts, etc.

Machine detail
Energy Saving
Conveyor belt dryers use hot air circulation technology, with gas consumption of only 6-12m³/h and diesel consumption of 8-12kg/h, which saves more than 30% energy compared with traditional equipment.
Efficient And Continuous Operation
The belt dryer adopts an advanced transmission system, which can achieve 24-hour uninterrupted and stable operation. The three-layer model has an hourly production capacity of 100-150KG, and the five-layer model reaches 150-200KG, which can meet the needs of fast delivery of large-scale wholesale orders.
Precise And Uniform Drying
Conveyor belt dryers use hot air circulation technology to ensure that the material is evenly dried 360° without dead corners, and the temperature is constant at 140°C to avoid local overheating or insufficient drying, ensuring product quality consistency.
