As a leading manufacturer based in Hengshui, Hebei, China, Anping County Boli Hardware Wiremesh Products Factory has been dedicated to producing high-quality wire mesh products since 1998. Our Heat Resistant Food Grade 304/316 Stainless Steel Spiral Wire Mesh Conveyor Belt for Drying Line is engineered to deliver exceptional performance in demanding industrial drying applications. With an annual export value of US$5 million to US$10 million and serving markets across North America, South America, Europe, Southeast Asia, Africa, and Oceania, we combine decades of expertise with advanced manufacturing techniques to offer a reliable, durable, and hygienic conveyor solution. This belt is designed to withstand high temperatures while maintaining food-grade safety standards, making it an ideal choice for food processing, chemical drying, and other heat-intensive operations.
Our spiral wire mesh conveyor belt is constructed from premium 304 or 316 stainless steel, ensuring excellent corrosion resistance, strength, and longevity. The unique spiral design provides a smooth, flat surface that facilitates even product distribution and efficient air or heat flow during drying. This belt is customizable in width, mesh size, and edge configuration to meet specific line requirements. Whether you are drying fruits, vegetables, seafood, or industrial components, this belt offers consistent performance under continuous thermal stress.
Key Features & Technical Specifications
- Material Options: Available in AISI 304 (for general food processing) or AISI 316 (for more corrosive environments, such as acidic or salty conditions). Both grades are FDA-compliant and suitable for direct food contact.
- Heat Resistance: Capable of operating continuously at temperatures up to 800°C (depending on material and design), with excellent dimensional stability under thermal cycling.
- Spiral Wire Construction: Interlocking spiral wires are connected by straight rods, creating a strong, flexible belt that resists distortion and prolongs service life.
- Open Mesh Design: Customizable mesh openings (typically 2mm to 20mm) allow for optimal air circulation, liquid drainage, and product visibility.
- Customizable Width & Length: Belt width can be tailored from 100mm up to 3000mm, with length as required.
- Edge Options: Available with welded mesh edges, twisted edges, or reinforced edges to prevent fraying and improve tracking.
- Surface Finish: Smooth, polished surface reduces product adhesion and makes cleaning easier; optional non-stick coating available upon request.
- High Load Capacity: The robust spiral structure supports heavy loads while maintaining uniform tension distribution.
- Easy Maintenance: The open structure allows debris to pass through, minimizing buildup and simplifying cleaning procedures.
- Customized Drive Systems: Compatible with various sprocket types, pulleys, and drive configurations to fit existing equipment.

Benefits for Your Drying Line
- Enhanced Drying Efficiency: The open mesh structure allows hot air to circulate freely around products, reducing drying time and energy consumption.
- Food Safety Compliance: Made from food-grade 304/316 stainless steel, this belt meets strict hygiene requirements for processing fruits, vegetables, meat, and seafood. The smooth surface prevents bacterial growth and is easy to clean.
- Long Service Life: The spiral design distributes stress evenly, minimizing wear and tear even under continuous high-temperature operation. This reduces replacement costs and downtime.
- Reduced Product Damage: The flat, even surface prevents product deformation or sticking, ensuring consistent quality in dried output.
- Flexible Integration: Can be retrofitted into existing drying lines with minimal modifications. Compatible with standard sprockets and drive systems.
- Low Maintenance: Self-cleaning mesh design reduces accumulation of residues. Routine cleaning with water or steam is sufficient.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between 304 and 316 stainless steel for this belt?
A: 304 stainless steel offers good corrosion resistance and is suitable for most food drying applications. 316 stainless steel contains molybdenum, providing enhanced resistance to chlorides, acids, and high-temperature oxidation. If your drying line involves salty or acidic environments, 316 is recommended. -
Q: Can the belt operate at temperatures above 800°C?
A: The maximum continuous operating temperature depends on the alloy and load conditions. For 316 stainless steel, safe operation up to 800°C is typical. For higher temperatures, we can discuss alternative materials like heat-resistant alloys. Please consult our technical team for your specific requirements. -
Q: What is the typical lead time for custom belts?
A: Standard lead time is 15–25 working days after order confirmation, depending on complexity and quantity. Urgent orders can be expedited with prior arrangement. -
Q: How do I determine the correct mesh size for my drying application?
A: Mesh size should be chosen based on product dimensions and airflow needs. For small products (e.g., grains, seeds), a smaller mesh (2–5mm) prevents falling through. For larger items (e.g., fruits, vegetables), larger openings (10–20mm) improve airflow. We can provide samples for testing. -
Q: Is the belt FDA approved for direct food contact?
A: Yes, our 304 and 316 stainless steel belts are manufactured from materials that comply with FDA regulations for food contact surfaces. They are also EU-compliant (EC 1935/2004). Specific certifications are available upon request. -
Q: Do you provide installation and maintenance guidance?
A: Absolutely. We provide detailed installation instructions, tensioning recommendations, and cleaning procedures. Our technical support team is available via email or video call to assist with troubleshooting. -
Q: Can I get a sample belt for testing before placing a bulk order?
A: Yes, we offer samples of small sections (e.g., 300mm x 300mm) for evaluation. Sample fees may apply, but are refundable with bulk orders. Contact us for details. -
Q: What are the packaging and shipping methods?
A: Belts are rolled onto wooden spools or pallets, wrapped in protective materials, and then placed in plywood crates or steel frames for export. We ship via sea, air, or express (DHL, FedEx, UPS) depending on your preference.
