Fruit and Vegetable Conveyor Belt

SHUNNAI Fruit and Vegetable Conveyor Belt is specially developed for washing, drying, sorting, grading, inspection and packaging lines of fresh produce. Different from ordinary industrial belts, fruit and vegetable conveying requires not only stable running performance but also gentle product handling, drainage efficiency and long-term resistance to water, fruit acids and cleaning chemicals. 

Every belt undergoes food-contact safety inspection, hydrolysis resistance testing, surface cleanliness evaluation, anti-slip testing and drainage performance verification before delivery. Through precise material selection and structural customization, SHUNNAI helps food processors reduce product damage, improve sorting accuracy and maintain continuous production efficiency in demanding wet processing environments.

Reduce Produce Loss During Conveying

Fresh fruits and vegetables are highly sensitive to impact, friction and pressure. During automated processing, even small surface damage can reduce product value, especially for strawberries, blueberries, cherries and other delicate produce. Therefore, the conveying system must control contact force while maintaining accurate movement.

SHUNNAI designs the Fruit and Vegetable Conveyor Belt with food-grade flexible materials and optimized surface structures. PU and silicone materials provide controlled elasticity, absorbing impact when products transfer between different processing stages. The belt hardness can be adjusted according to product characteristics, allowing soft fruits to be transported without crushing while still maintaining sufficient support for heavier products such as apples, potatoes and carrots.

For inspection and sorting applications, SHUNNAI offers matte smooth surfaces that reduce light reflection and improve compatibility with optical sorting equipment. Light-textured surfaces increase friction without damaging the natural surface layer of fruits, helping maintain appearance quality during high-speed conveying.

Stable Performance in Wet Processing Lines

Fruit and vegetable processing environments usually involve continuous water spraying, soaking, disinfecting and drying cycles. These conditions create higher requirements for belt material stability. Ordinary belts may absorb water, soften, expand or develop surface cracks after long-term operation.

SHUNNAI selects hydrolysis-resistant PU, silicone and TPE materials according to different working conditions. The dense surface structure prevents juice, water and cleaning agents from penetrating into the belt body. Even when exposed to fruit acids such as citric acid and malic acid, the belt maintains stable dimensions and surface performance.

For washing and dewatering equipment, SHUNNAI provides perforated and mesh structures that allow water and impurities to pass through quickly. This design reduces water accumulation on the conveying surface, improves cleaning efficiency and helps maintain a cleaner processing environment.

Improve Sorting Accuracy on Automated Lines

Modern fruit and vegetable processing plants increasingly rely on automatic weighing, color recognition and quality inspection systems. During these processes, unstable belt movement, product rolling or surface reflection can directly affect detection accuracy and production efficiency.

SHUNNAI Fruit and Vegetable Conveyor Belt is designed according to the requirements of intelligent sorting equipment. The belt body uses high-dimensional stability fabric reinforcement or integrated polymer structures to reduce lateral deformation during continuous operation. This helps maintain consistent conveying speed and positioning accuracy, allowing inspection cameras and weighing systems to capture reliable product information.

For optical sorting lines, SHUNNAI provides low-reflection matte surfaces that reduce interference caused by strong light reflection from wet fruit surfaces. For grading systems, customized surface patterns provide moderate friction, preventing round products from rolling or changing position before measurement. Flexible sidewalls and divider structures can also be added to maintain product spacing and improve automatic sorting efficiency.

Adapt to Seasonal Processing Changes

Fruit and vegetable production has strong seasonal characteristics. Processing plants may handle different products throughout the year, from soft berries in summer to frozen vegetables in winter. A single conveying system often needs to adapt to changing temperatures, moisture levels and product characteristics.

SHUNNAI develops different belt structures according to seasonal production requirements. Silicone belts maintain flexibility in low-temperature environments and are suitable for chilled or frozen product handling. PU belts provide balanced strength and flexibility for daily washing, sorting and packaging operations. TPE and special composite belts can be selected for applications requiring repeated temperature changes.

This material flexibility allows processors to reduce frequent belt replacement caused by seasonal environmental changes and maintain stable operation throughout the production cycle.

Cleaning Efficiency and Maintenance Control

In fresh produce processing, cleaning time directly affects production capacity. Traditional conveyor belts with fabric layers or uneven joints may collect fruit residue, water and microorganisms, increasing cleaning difficulty and maintenance frequency.

SHUNNAI Fruit and Vegetable Conveyor Belt adopts dense food-grade surface structures and supports seamless endless processing. The smooth belt surface reduces residue accumulation, while the jointless design eliminates raised areas that may damage products or collect contaminants.

The belt material is compatible with common food processing cleaning methods, including water flushing, alkaline cleaning agents and disinfectant treatment. For high-humidity washing lines, mesh and punched structures improve drainage performance, reducing standing water and shortening drying time after cleaning.
