Modular Belts for Fruit and Vegetable Processing
Modular Belts for Fruit & Vegetable Processing
Gentle handling, maximum airflow, and rapid drainage — Modutech modular belts for washing, sorting, grading, drying, IQF freezing, and packaging of fresh and frozen produce. FDA and EU compliant for direct food contact.
Why Modutech for Produce Processing?
Fresh produce processing demands belts that handle delicate products without bruising, drain water rapidly during washing stages, provide airflow for drying and cooling, and withstand temperatures from blast freezing at -73°C to warm-water washing at +60°C. The belt surface must be gentle enough for ripe berries yet strong enough for bulk potatoes and root vegetables.
Modutech's flush grid models deliver the open area needed for washing and IQF — the MD254 FG at 33% and MD254 GAP at 48% provide rapid water drainage without letting small produce fall through. The EC254 C flat top handles gentle sorting and grading without surface damage.
Every Modutech material is FDA and EU 10/2011 compliant. The modular design means individual damaged modules can be swapped in minutes — critical during harvest season when downtime means lost product.

| Sorting & Grading | EC254 C | Smooth flat top for gentle handling during manual and optical sorting without bruising. |
| Peeling & Cutting | EC254 C, EC508 C | Easy-clean flat top for cut produce. EC508 for heavier root vegetables and melons. |
| Drying | MD254 FG, EC127 FG | Flush grid airflow for forced-air drying. EC127 FG for small items like berries and peas. |
| Blanching | EC508 PR22 | Perforated for steam and water flow. POM rated to +110°C for hot-water blanching systems. |
| IQF Freezing | EC508 PR22, EC254 PR16 | Maximum airflow in PE (-73°C) for individual quick freezing. EC254 PR16 for smaller items. |
| Cooling | EC127 FG, MD254 FG | Flush grid for ambient and forced-air cooling. EC127 FG for delicate items on compact lines. |
| Incline / Elevation | EC127 GT | Non-marking grip top for elevation changes. Gentle on delicate produce. FDA approved surface. |
| Packaging | EC127 C, EC254 C | Smooth transfer for bagged, clam-shell, and tray-packed produce. EC127 for tight-transfer machines. |
Produce-Specific Considerations
Ripe berries, tomatoes, and stone fruit require surfaces that won't bruise or mark. EC254 C and EC127 C flat tops provide smooth, low-friction transfer. Flush grid supports products evenly without pressure points.
Produce washing uses high volumes of water, often with chlorine or ozone. MD254 GAP (48% open) drains fastest. MD254 FG (33%) balances drainage with product support. Open-hinge design prevents water pooling in belt structure.
From hot-water blanching (+90°C) to IQF blast freezing (-73°C), produce processing spans an extreme range. POM handles -43°C to +110°C. PE extends to -73°C. PP for standard room-temp processing.
Harvest season means running 24/7 with zero tolerance for downtime. Modular construction allows damaged modules to be replaced in minutes without removing the entire belt. Keep spare modules on hand for instant repairs.
Material Selection for Produce
| Material | Temp Range | Produce Applications | Key Properties |
|---|---|---|---|
| Polypropylene (PP) | +5°C to +90°C | Sorting, grading, packing, ambient cooling, warm wash | Low friction, good chemical resistance, lightest weight |
| Polyethylene (PE) | -73°C to +66°C | IQF freezing, blast freezing, frozen storage transfer | Sub-zero rated, flexible at low temps, FDA compliant |
| Acetal (POM) | -43°C to +110°C | Blanching, wide temp range, highest strength lines | Heat resistant, strongest, best for aggressive CIP |
All materials FDA and EU 10/2011 compliant. Resistant to chlorine, ozone, peracetic acid, and other produce sanitation chemicals.
Produce Applications
EC127 FG flush grid for washing and drying. Gentle handling prevents leaf bruising and tearing. 25% open area for water drainage and forced-air drying in spin-dry and tunnel systems.
EC127 C flat top for gentle sorting — smoothest surface available. EC254 PR16 for IQF tunnels where berries freeze individually. Non-marking surfaces prevent cosmetic damage to premium fruit.
EC508 C for heavy bulk loads from receiving through cutting. MD254 GAP (48% open) for high-volume washing lines. POM material for french fry blanching at +90°C.
EC508 PR22 in PE (-73°C) for IQF peas, corn, carrots, and mixed vegetables. 22% open area ensures each piece freezes individually. Heavy supports carry bulk loads through spiral IQF tiers.
EC254 C for sorting and grading lines. MD254 FG for waxing and drying stages where airflow is needed. EC127 GT grip top for elevation changes between processing and packing levels.
EC254 C easy-clean surface for cut produce — reduces sanitation time 70%. EC127 C for tight-transfer packaging machines. Open-hinge supports the frequent sanitation cycles ready-to-eat products require.
Frequently Asked Questions
Which belt is best for washing produce?
The MD254 GAP with 48% open area provides the fastest drainage for high-volume washing lines. For lighter produce that needs more surface support, the MD254 FG at 33% offers a good balance. Both are medium-duty strength and handle chlorinated and ozonated wash water without degradation.
What belt do I need for IQF frozen vegetables?
The EC508 PR22 in Polyethylene (PE) rated to -73°C is the standard for IQF. The 22% open area allows cold air to reach each piece for uniform individual freezing. For smaller items like peas and diced vegetables, the EC254 PR16 at 1" pitch keeps small pieces from falling through while still providing airflow.
Will modular belts bruise delicate produce?
No. The EC127 C and EC254 C flat top surfaces are smooth, low-friction, and non-marking. They're used for berries, tomatoes, and other delicate produce without cosmetic damage. Flush grid models (EC127 FG, MD254 FG) support products evenly across the grid without creating pressure points that cause bruising.
Can Modutech belts handle blanching temperatures?
Yes. Acetal (POM) is rated to +110°C / +230°F and handles hot-water and steam blanching for french fries, vegetables, and other products. POM also provides the highest belt strength for carrying heavy loads through blanching systems. PP is limited to +90°C for warm-wash applications.
How do I handle small items like peas and corn on modular belts?
Use the EC254 PR16 (16% perforated) or EC127 FG (25% flush grid) — both provide airflow and drainage while keeping small items on the belt surface. For the smallest items, the EC127 C flat top (0% open) provides a completely closed surface with the tightest 0.5" pitch transfer gap.
