The advantages of efficient drying technology for belt dryers and how to maintain it scientifically?

With the continuous improvement of drying efficiency and quality requirements in modern industry, mesh belt dryers have become important equipment in industries such as food, chemical, and metallurgy due to their unique structural design and intelligent functions. Jinlu Machinery will provide a detailed introduction to the technical advantages of the mesh belt dryer and systematically outline its daily and scientific maintenance methods to help users extend equipment life and ensure production efficiency.

1、 Core advantages of mesh belt dryer

① Layered design improves drying efficiency

The layered mesh belt dryer uses multiple layers of staggered conveyor belts to achieve natural material dropping and conversion inside the drying box. This design not only extends the drying time of the material, but also avoids the problem of large footprint of traditional single-layer structures. Through independent heating and dehumidification systems, each layer of mesh belt can accurately control temperature and humidity, significantly improving drying uniformity and efficiency.

② Uniform fabric technology optimizes drying effect

The mesh belt dryer with uniform fabric function disperses the material twice through an obtuse triangular transition belt and a dispersing disc structure, ensuring more thorough contact with hot air. At the same time, the preheating shell design utilizes the waste heat in the drying chamber to pre dry the materials, further reducing energy consumption.

③ Energy saving, environmental protection, and flexible adaptation

The mesh belt dryer adopts a circulating hot air system, and most of the hot air can be reused, significantly reducing energy consumption. The equipment is compatible with multiple heat sources (steam, thermal oil, electricity or gas), and can flexibly increase the number of drying stages according to production needs to meet the production needs of different scales.

2、 Key points for maintenance and upkeep of mesh belt dryer

① Daily operation precautions

Shutdown standard: After each operation, the temperature adjustment knob should be reset to zero to avoid loss of the solenoid valve due to misoperation.

Filter screen inspection: Before daily use, check whether the filter screen is clogged to ensure sufficient air flow, otherwise it will lead to a decrease in drying efficiency.

Lubrication management: Butter should be added to the bearing seat every month to maintain good lubrication of the bearings and avoid equipment damage caused by excessive friction.

② Key steps for regular maintenance

Cleaning of exhaust system: Clean the exhaust ducts and bends monthly to prevent moisture accumulation from affecting drying efficiency.

Mesh belt inspection and replacement: If the drying mesh is found to be worn or damaged, it should be replaced in a timely manner. When replacing, it is necessary to first remove the sprocket at the main transmission end, adjust the tension of the chain, and ensure that the tension on both sides is consistent.

Gearbox and gear maintenance: After 5000 hours of operation, the PLC battery needs to be replaced. After 10000 hours, the wear of the gearbox gears should be checked, and industrial extreme pressure gear oil that meets the standards should be replaced.

③ Long term shutdown storage and restart

When the equipment is not in use for a long time, the power and heat sources should be cut off, and lubricating oil should be added to key components such as the gearbox. The storage environment should be kept dry and ventilated to avoid the influence of corrosive media. Before re enabling, a comprehensive performance test is required to ensure that the device is running properly.

3、 Industry Outlook

With the application of intelligent technology, future mesh belt dryers will further improve their automation level, such as real-time monitoring of equipment status through the Internet of Things, predicting maintenance cycles, and reducing unplanned downtime.

The high efficiency and versatility of the mesh belt dryer make it the preferred equipment for modern industrial drying. Through scientific maintenance and regular upkeep, users can not only extend the lifespan of the equipment, but also ensure the stable operation of the production line. Enterprises should choose suitable drying technologies based on their own production needs and establish standardized maintenance processes to maximize equipment value.
