Nut Conveyor Belt

The Nut Conveyor Belt is specially designed for food processing environments where cleanliness, gentle handling and stable operation are critical. Using food-grade PU, PVC or thermoplastic materials combined with high-strength polyester carcass, SHUNNAI belts provide excellent resistance against oil, moisture and continuous production stress. The smooth belt surface reduces nut cracking, shell breakage and kernel damage during transportation, helping processors maintain higher product yield.

All food-contact materials comply with international hygiene requirements and can provide FDA-related material reports, MA inspection support and CNAS laboratory testing documents. With GB/T 19001-2016 / ISO 9001:2015 quality management system control, every production batch is inspected for dimensional accuracy, surface quality and performance stability before shipment.

Designed for Different Nut Processing Stages

Nut processing lines usually include raw material feeding, cleaning, drying, roasting, cooling, shell separation, sorting, grading and packaging. Each stage has different requirements for belt material, surface structure and running stability.

Raw Nut Feeding and Transfer

During initial feeding, nuts often contain shells, dust, soil particles or irregular shapes. SHUNNAI belts use wear-resistant surface materials that can withstand continuous impact from raw materials while maintaining stable conveying speed. The belt structure can be customized according to hopper height, feeding angle and equipment layout, reducing material accumulation at transfer points.

Roasting and Cooling Conveying

After roasting, nuts require controlled cooling before further processing or packaging. High-temperature resistant PU solutions are available for sections exposed to heat, while low-moisture absorption materials prevent belt deformation caused by temperature and humidity changes.

The stable running performance helps maintain consistent cooling time, preventing uneven product quality caused by belt speed fluctuation. For food manufacturers with continuous production lines, this reduces manual adjustment and improves process efficiency.

Food Safety and Clean Production Requirements

Low Contamination Risk Surface

Nut products are directly consumed after processing, making foreign matter control a key concern for buyers. Ordinary industrial belts may generate particles after long-term friction, creating potential contamination risks. SHUNNAI uses dense polymer cover materials with smooth surfaces to reduce powder shedding and material residue accumulation.

The non-toxic and odorless belt surface avoids affecting the natural flavor of nuts. It is suitable for processing environments requiring strict hygiene management, including nut roasting plants, snack manufacturers and export food factories.

Easy Cleaning and Maintenance

Nut processing often involves oil, fine powder and small particles that may remain on conveyor surfaces. SHUNNAI belts can be supplied with smooth, matte or customized texture surfaces according to cleaning requirements.

The surface design helps operators remove residues through dry cleaning, compressed air cleaning or approved washing methods. Reduced cleaning difficulty means shorter downtime between production batches and easier compliance with factory hygiene procedures.

Protection Against Nut Damage During Conveying

Reducing Shell Breakage and Kernel Loss

Nuts are fragile agricultural products. Excessive impact, hard belt surfaces or unstable running conditions may cause shell cracking and kernel damage, reducing final product value. SHUNNAI conveyor solutions focus on balancing belt strength and surface softness.

The elastic polymer cover absorbs minor impact during transportation, while the stable carcass structure prevents excessive stretching. This combination helps maintain smooth movement from sorting equipment to packaging stations.

Stable Conveying for Different Nut Sizes

Different nuts require different conveying conditions. Large walnuts, irregular almonds and small peanuts may need different belt thickness, surface pattern and guide structures.

SHUNNAI supports customized solutions including belt thickness, width, surface pattern, guide strips and sidewalls, allowing manufacturers to match their existing processing equipment without major modification.

Application Areas in Nut Processing Lines

SHUNNAI Nut Conveyor Belt solutions are developed according to different processing requirements, from raw material receiving to final package transfer. Different belt structures can be selected according to product characteristics, production speed and sanitation requirements.

Sorting and Grading Equipment

Optical sorting and size grading machines require stable belt movement and consistent product positioning. SHUNNAI belts provide uniform thickness and accurate running performance, helping nuts pass through inspection areas at a constant speed.

For color sorting applications, special matte surface designs are available to reduce excessive reflection under camera lighting. This improves visual recognition conditions and supports stable operation of automated sorting equipment.

Packing and Weighing Lines

After grading, nuts are transported to weighing, filling and packaging stations. The conveyor belt needs to maintain accurate positioning while handling continuous product flow. SHUNNAI provides anti-slip surface options that prevent nut rolling and product accumulation during transfer.

Sidewalls, guide strips and customized profiles can be added according to packaging equipment requirements, helping factories achieve smoother automatic feeding and reduce manual intervention.

Washing and Pre-Processing Sections

Some nut processing plants include washing, soaking or cleaning procedures before drying and roasting. For these humid environments, SHUNNAI offers hydrolysis-resistant belt materials with stable dimensional performance.

The belt surface maintains good resistance against water, mild cleaning agents and food processing conditions, reducing problems such as swelling, delamination or deformation caused by long-term moisture exposure.

Customization Options for Different Production Lines

Material Selection Based on Working Conditions

SHUNNAI selects belt materials according to processing temperature, cleaning method and product characteristics. Food-grade PU belts are suitable for applications requiring cleanliness and flexibility. PVC belts provide economical solutions for general conveying. Modified materials are available for higher temperature or special environments.

Surface Structure and Belt Design

The conveying surface can be customized with smooth finish, fine texture, anti-slip patterns or other structures according to production requirements. Smooth surfaces are suitable for sorting and packaging, while textured surfaces provide better control for inclined conveying.

For applications involving small nuts or unstable materials, SHUNNAI can supply belts with guide strips, sidewalls and cleats to improve conveying accuracy and prevent material falling.
