Industrial Belt Dryer for Pulp Molding
As a leading manufacturer of pulp molding equipment, AGICO Group is committed to providing efficient, reliable, and energy-saving drying solutions for the pulp molding industry. Our Single Layer Belt Dryer is a high-performance industrial belt dryer specifically engineered to meet the demanding requirements of continuous production lines, such as egg tray production lines, fruit tray lines, cup carrier lines, and other molded fiber products.
The AGICO single-layer belt dryer is a continuous belt dryer based on through-air drying technology. It is designed for materials with good air permeability, including sheet-shaped, strip-shaped, and formed pulp products with high initial moisture content. By combining stable mechanical structure, uniform hot air distribution, and flexible process control, this belt dryer ensures fast moisture removal while maintaining excellent product quality and dimensional stability.
Designed for Continuous and Stable Industrial Drying
In modern pulp molding plants, drying is one of the most energy-intensive and quality-critical processes. Freshly molded pulp products typically contain 70–75% moisture, which must be reduced to around 10–12% before they can be safely stacked, packaged, or further processed. From egg trays and fruit trays to industrial packaging and disposable tableware, all molded fiber products must undergo a controlled and efficient drying process after forming. AGICO’s industrial belt dryer is purpose-built to handle this challenge efficiently and continuously.
Traditional drying methods, such as natural air drying or batch chamber dryers, often fail to meet the demands of modern, large-scale pulp molding plants. These methods are slow, inconsistent, labor-intensive, and difficult to integrate into automated production lines.
Unlike batch drying systems, the single layer belt dryer allows products to move steadily through the drying chamber on a stainless-steel mesh belt. This continuous belt dryer design enables uninterrupted operation, making it ideal for medium- to large-scale pulp molding production lines that require high output and consistent quality.

AGICO Belt Dryer Features
Optimized Single-Layer Belt Dryer Structure
The single-layer configuration ensures that each molded product is evenly exposed to controlled hot airflow. Hot air passes through the material layer from bottom to top or top to bottom, completing efficient heat and mass transfer while carrying away moisture. This through-flow drying method significantly improves evaporation intensity and drying speed compared with conventional surface heating systems.
The dryer body is modular in design and consists of multiple independent drying units. Each unit features its own air circulation system, allowing precise adjustment of temperature, airflow volume, and humidity extraction. This modular structure not only improves drying uniformity but also provides flexibility for future capacity expansion.
High Adaptability for Pulp Molding Products
AGICO’s belt dryer is particularly suitable for pulp molded products that require moderate drying temperatures and strict shape control. Improper drying can easily lead to warping, uneven shrinkage, cracking, or insufficient strength. By maintaining stable airflow and temperature profiles, the AGICO industrial belt dryer helps manufacturers achieve strong, smooth, and visually consistent finished products.
In addition to molded pulp trays, the dryer can also be adapted for other materials with similar drying characteristics. Its robust design and adjustable operating parameters make it a versatile solution for various industrial drying applications where a reliable belt dryer is required.
Built with Energy Efficiency and Reliability in Mind
Energy efficiency is a key consideration in today’s pulp molding plants. The AGICO single layer belt dryer incorporates a high air-recirculation ratio, allowing most of the heated air to be reused within the system. Only a controlled portion of moist exhaust air is discharged through dedicated dehumidifying fans, effectively reducing overall energy consumption while maintaining drying performance.
With flexible heat source options—including steam, thermal oil, electricity, or hot air furnaces powered by coal or fuel oil—the dryer can be seamlessly integrated into different plant infrastructures worldwide.

Single Layer Belt Dryer Working Principle
The material is evenly spread onto a mesh belt by a feeder. The mesh belt is typically made of 12-60 mesh stainless steel wire and is driven by a transmission device to move within the dryer. The dryer consists of several units, each with independent hot air circulation. Some exhaust gas is discharged by a dedicated dehumidifying fan, and the exhaust gas is controlled by a regulating valve. Hot air passes through the material-covered mesh belt from bottom to top or top to bottom, completing the heat and mass transfer process and removing moisture from the material. The mesh belt moves slowly, and its operating speed can be freely adjusted according to the material temperature. The dried finished product continuously falls into a collector. Upper and lower circulation units can be flexibly configured according to user needs, and the number of units can also be selected as required.
