The best solution for transporting sugar
In the demanding world of the sugar industry, choosing the right conveyor belt material is not just a matter of efficiency; it is a critical decision that impacts hygiene, product quality and long-term operating costs. While PVC belts have traditionally been used for a variety of conveyor applications, when it comes to sugar transportation, white food-grade rubber conveyor belts consistently prove to be the better choice. It is a fundamental difference in material properties that directly addresses the unique challenges associated with sugar.
Here is why white food-grade rubber belts are the best solution for sugar transportation:
1. Increased strength and durability
Sugar, in its crystalline form, is a highly abrasive product. The physical properties of rubber provide a significant advantage in terms of belt life.
Excellent abrasion resistance: Food grade rubber fabric belt composites are designed to withstand the abrasive nature of sugar crystals, minimizing belt surface wear. This means longer service life and fewer costly belt replacements. PVC, being a harder material, is more susceptible to surface abrasion and degradation from abrasive materials.
Strength and tear: Food grade rubber belts are based on a polyester/polyamide (EP) cord with a tensile strength of 200 to 2500 N/mm. This allows the belts to be installed in elevators, conveyors of long lengths and with heavy loads. Food grade PVC tapes have a maximum tensile strength of up to 500 N/mm, which often leads to problems with stretching and tearing of the belt.
-
Cover Thicknesses: PVC belts have standard ply thicknesses of 2+1 mm, which is often insufficient and leads to belt abrasion after 5-6 months of intensive use. Rubber food belts can have ply thicknesses of up to 10 mm on the top and 5 mm on the bottom, which, combined with the significantly higher abrasion resistance of rubber belts, makes them a long-lasting solution for sugar transportation.
-
Flexibility and Impact Resistance: Rubber has excellent elasticity and flexibility compared to PVC. This allows rubber belts to absorb shocks more effectively, reducing the likelihood of damage from falling sugar. This is especially useful in operations where sugar is dropped from a height onto the belt.
-
Temperature Stability: Although sugar itself is not typically transported at extreme temperatures, the production environment may vary. Food-grade rubber typically offers better temperature stability than PVC, maintaining its physical properties over a wider range of operating temperatures without becoming brittle or excessively hard.

High hygiene and food safety
A major challenge in the sugar industry is to prevent contamination and foreign substances from entering the finished product. This is where food grade rubber really stands out.
Food grade compliance: White food grade rubber belts are specifically manufactured to meet strict international food safety standards (e.g. FDA, EU regulations). This means they are designed to not leach harmful chemicals into the sugar, ensuring product purity and consumer safety. Fabric rubber belts can be manufactured with a full rubber moulded edge, eliminating the problem of cords and their possible entry into the product.

Long-term Cost-Effectiveness
While the initial cost of a high-quality food-grade rubber belt is higher than standard PVC belt, the long-term economic benefits are undeniable and the total cost of ownership of a rubber-fabric belt is significantly lower.
Lower maintenance and replacement costs: Due to their superior durability and easier cleaning, rubber belts require less frequent maintenance and replacement, resulting in significant savings over their lifetime.
Reduced downtime: Fewer belt failures and faster cleaning times contribute to increased uptime and increased productivity, which directly impacts profitability.
Minimized product contamination and recalls: The improved hygiene and food safety offered by rubber belts dramatically reduce the risk of product contamination, preventing costly recalls and reputational damage.

For sugar transportation, the advantages of white food grade rubber conveyor belts over PVC belts are clear and convincing. From ensuring the highest standards of hygiene and food safety to providing exceptional durability, efficiency and long-term cost savings, rubber belts are the smart choice for any production that strives for quality, safety and profitability. Investing in the right conveyor belt material is an investment in the integrity of your product and the efficiency of your entire production line.
