5 Must-Have Features in a Cold Resistant Conveyor Belt

Cold storage facilities are all about precision and efficiency. Whether it’s a freezer or chilled storage, conveyors automate and streamline operations.

In a busy cold storage warehouse, improving productivity is key to staying ahead. Conveyors reduce manual labor, cut down errors, and ensure that your goods stay in pristine condition. In temperature-controlled spaces, the right conveyor is a lifesaver.

But cold storage isn’t without its challenges. From freezing temperatures and condensation to constant wear and tear, these environments demand specialized equipment. Choosing the right conveyor can also have a big impact on your production lines, supply chain, and operating costs.

So how do you make the best decision? Let’s break it down.

How Temperature Affects Conveyors

Cold temperatures aren’t just uncomfortable for people – they’re tough on equipment too. In cold rooms or food processing, conveyors can crack, motors can seize, and performance can drop if not built for the cold. Extreme cold can make standard conveyor materials brittle and compromise their lifespan. For businesses relying on the cold chain to move frozen foods efficiently, this can be a big problem.

Tailoring to Specific Temperature Ranges

Not all cold storage facilities are the same. A chiller room might hover around 34°F, while a deep-freeze environment can dip to -20°F or lower. Choosing a conveyor designed for your specific temperature range is crucial. For frozen or temperature-sensitive items, choose conveyors with insulated motors and cold-resistant materials for reliable performance.

Don’t Forget Humidity and Condensation

Humidity and condensation can wreak havoc in cold storage. These elements can lead to slippery surfaces, rust, and even electrical failures. In food processing environments, selecting a conveyor with moisture-resistant components and proper drainage is essential. It’ll save you from constant maintenance woes and help keep your cold chain running smoothly.

Cold-Resistant Conveyor Belts

The conveyor belt is the workhorse of the system, so it needs to be tough. Choose belts made from materials specifically designed to resist brittleness and cracking in low temperatures. This ensures reliable performance even in freezing environments and extends the lifespan of your equipment.

Rust-Resistant Frames and Rollers

Rust is a conveyor’s worst enemy in cold, damp conditions. Stainless steel frames and rollers are your best bet for durability and corrosion resistance. They’ll keep your system running smoothly without succumbing to the elements.

Preventing Abrasion and Wear

Low temperatures can make some materials more prone to wear and tear. Opt for conveyor components that are abrasion-resistant to ensure longevity. Nobody wants to replace parts every few months because the cold has taken its toll.

Motors That Thrive in the Cold

Freezing conditions can make some motors perform worse than others. Sealed and insulated motors handle the cold without freezing or collecting moisture. These motors ensure that your conveyor keeps running smoothly, no matter how low the temperature dips.

Energy Efficiency Matters

Energy-efficient motors are a must in cold storage facilities, where power bills can skyrocket. Look for low-maintenance, high-efficiency motors to save on energy costs while ensuring reliable performance.

Drive System Design

The drive system is another critical component. Whether chain-driven or belt-driven, ensure the system prevents slippage and withstands low temperatures.

Selecting the Right Conveyor for Cold Storage: Belt vs. Roller Conveyors

Each has its perks. Belt conveyors are great for handling smaller items and ensuring smooth transport, while roller conveyors excel with heavier loads. Consider your product types and choose accordingly.

The Magic of Modular Conveyors

Modular conveyor systems are like the Swiss Army knife of material handling. They’re easy to adjust, maintain, and upgrade, ideal for cold storage facilities with changing layouts.

Vertical and Inclined Conveyors

When space is tight, vertical and inclined conveyors can maximize your facility’s efficiency. They’re ideal for moving products between levels without taking up valuable floor space.

Low-Maintenance Solutions

Maintenance in cold storage can be tricky. The last thing you want is to shut down operations for repairs. Opt for conveyors with low-maintenance designs to keep your facility running smoothly.

Long-Lasting Components

Durable components built for harsh conditions minimize downtime and keep your system in top shape. Invest in quality now to save on repair costs later.

Routine Maintenance Tips

Regularly inspect your conveyor for wear and tear, especially in key areas like belts and motors. Addressing small issues early can prevent bigger problems down the line.

Testing for cold resistance

There are no current internationally recognised test methods for specifically determining a conveyor belt’s ability to function in extremely cold conditions. At Dunlop we carry out laboratory testing using a liquid nitrogen freezing cabinet to test samples of rubber belting at extreme low temperatures.

Belt samples are frozen using liquid nitrogen

The elastic modulus of the samples are first measured at an ambient temperature of 20°C. The samples are then placed inside the cabinet. The temperature in the cabinet is then gradually reduced by stages of 5°C. The elastic modulus is measured at each stage to determine when the decrease in flexibility of the rubber becomes too great, thereby identifying its lowest permissible ambient temperature.
