The price of a belt dryer machine generally ranges from US$8,000 to over US$300,000, depending on capacity, heating source, belt width, automation level, material properties and whether it is supplied as a standalone machine or a complete drying system. Tell us your material and target moisture, and we'll recommend the most cost-effective solution.
A belt dryer performs best with materials that can be evenly distributed on the mesh belt, such as pellets, flakes, strips and slices. It is ideal for high-moisture, heat-sensitive products like fish feed, pet food, tofu cat litter, vegetables, herbs and seafood. Fibrous materials can also be dried efficiently. Paste-like materials should first be pelletized or extruded before entering the dryer.
The most common options include mesh belt dryer, continuous belt dryer, hot-air circulation belt dryers and multi-layer drying systems. The right configuration depends on your material characteristics, production capacity, energy source and moisture reduction requirements rather than machine size alone.
An effective belt dryer design starts with your raw material. We evaluate moisture content, particle size, product thickness, drying temperature, available energy, factory layout and required throughput before recommending the appropriate equipment configuration.
Yes. Our conveyor belt dryer design can operate as a standalone drying unit or be integrated into existing feed, biomass, food or industrial production lines. We customize the conveying system, control interface and equipment layout for smooth installation.
For medium and large production plants, a continuous conveyor dryer usually provides higher throughput, more consistent moisture control and lower labor requirements. Batch dryers remain suitable for laboratory production or products with frequent recipe changes.
In many cases, yes. A conveyor dryer machine can process different materials by adjusting temperature, belt speed, airflow and layer thickness. However, products with very different drying characteristics may require separate operating recipes or dedicated drying sections.
Yes. Belt dryers for biomass are widely used for sawdust, wood shavings, crop straw, bagasse and similar materials. We configure the system according to the initial moisture, target moisture, particle size and the downstream process, such as pellet production or direct fuel use.
Absolutely. Every industrial conveyor dryer is designed around the available installation space. Belt width, dryer length, belt layers, feeding direction and supporting equipment can all be optimized to fit existing buildings while maintaining the required production capacity.
Most customers purchase more than a belt dryer for sale. Depending on the project, we can supply feeding equipment, conveying systems, heat sources, dust collection, PLC controls, installation guidance, commissioning, operator training and complete turnkey drying systems from a single manufacturer.
In many cases, yes. If the products have similar drying characteristics, different recipes can be created by adjusting temperature, belt speed and airflow. We'll evaluate your product list before recommending one or multiple drying lines.
The most important data are raw material type, initial and target moisture, hourly capacity, particle size, available heat source and installation space. These allow us to configure the right continuous dryer machine for your project.
Yes. We often replace aging dryers while keeping existing upstream and downstream equipment. Our engineers redesign the interface dimensions and conveying layout to minimize civil work and production downtime.
That depends on local energy prices and plant conditions. Steam, natural gas, biomass, electricity and thermal oil all have different operating costs. We compare both investment and long-term energy consumption before making recommendations.
Some materials require special feeding methods or non-stick mesh belts. By selecting the proper air velocity, bed thickness and cleaning system, most sticky products can be dried reliably without affecting continuous production.
Yes. Our modular industrial belt dryer design allows additional drying sections, wider belts or higher-capacity conveying equipment to be added, making future expansion much easier than replacing the entire system.
There is no standard answer. The required footprint depends on drying time, belt width, heating method and production capacity. We provide a customized layout drawing before manufacturing begins.
Yes. Our conveyor drying systems are regularly integrated with existing extruders, pellet mills, granulators, crushers and packaging lines from different manufacturers through customized interface design.
It depends on the material. Some products only require removing 5–10% moisture, while others need much larger reductions. We calculate drying capacity based on evaporation load instead of using fixed moisture values.
Every belt dryer for sale from RICHI is engineered for a specific application instead of using a one-size-fits-all design. We optimize airflow, heating, conveying and automation according to your material, giving customers better performance and long-term reliability.
