C2050K2 Double Pitch Conveyor Chain
Model C216AL is a customized double pitch conveyor chain equipped with outboard nylon rollers, widely adopted for ice cream freezing tunnel production lines.
From the structural perspective, its external nylon rollers separate load-bearing and driving functions. The nylon rollers slide steadily along guide rails and undertake most material weight, while chain joints only transmit pulling force. This design effectively reduces abrasion on pins and sleeves, lowering maintenance frequency even under continuous low-temperature operating conditions. The extended pins and customized attachment plates reserved on the chain enable stable mounting of mould trays, ensuring ice cream moulds stay horizontal during long-distance circulation inside freezing tunnels.
In production operation, the chain delivers two core values. Firstly, low-friction nylon rollers operate quietly without frequent lubrication, avoiding contamination to food-grade production environments, which satisfies strict hygiene standards for frozen food manufacturing. Secondly, the 304 stainless steel chain body maintains stable mechanical performance under minus low temperatures. It supports uninterrupted cyclic transportation inside freezing tunnels, achieving consistent production rhythm for continuous ice cream forming and quick freezing.
Tailored for frozen food processing lines, C216AL nylon roller conveyor chain provides reliable long-term operation for ice cream tunnel conveying systems.

Key Technical Advantages for Ice Cream Quick Freezing
Engineered for Extreme Cold (-50°C Low-Temperature Embrittlement Resistance)
Standard conveyor chains suffer from structural micro-cracks and sudden brittle fracture when exposed to rapid cooling down to ultra-low temperatures. Our freezer tunnel tray chains are manufactured with specialized low-temperature alloy formulations and cryogenic heat treatments. This ensures high impact toughness, zero cold-brittleness, and dimensional stability during continuous thermo-cycling.
2. FDA/NSF Food-Grade Hygiene & Zero-Contamination Design
Designed specifically for food processing, the chain links feature smooth surfaces that prevent ice build-up and organic product accumulation. Pre-lubricated with NSF H1 food-grade low-temperature grease, the lubricant retains ideal viscosity without freezing or flaking, ensuring full compliance with international FDA food safety audit requirements.
3. High Load Stability in Quick Freezing & Hardening Tunnels
Ice cream tray conveyors carry heavy dynamic loads through narrow temperature-controlled tunnels. Our precision-forged pins and pitch control ensure zero elongation, smooth tray engagement, and reduced friction on drive sprockets-significantly reducing plant maintenance costs and line stops.
