Steaming

A steaming conveyor belt is a metal conveyor belt engineered to move food products through industrial steaming processes while supporting steam circulation, drainage and hygienic cleaning under continuous heat and humidity.

Steaming only works if heat, moisture and product movement stay in balance. The moment one of those three drifts, the result drifts with it: uneven texture, inconsistent cook, or product loss. In industrial food production, the conveyor belt is what keeps that balance in place. It carries the product, but it also governs steam exposure, residence time, drainage and how easily the line gets clean again.

Twentebelt has engineered metal conveyor belts for demanding steaming environments for over 100 years, from spiral steamers to continuous steaming lines and compact processing layouts. We configure each belt around your product, your process and your system, not the other way around.

We help machine builders and food processors get steaming lines that hold their process specification, clean fast and keep running.

Conveyor belts for industrial steaming applications

Industrial steaming uses controlled heat and moisture to cook, pasteurize, soften or condition a product before the next production step. The conveyor belt sits directly in that control loop. It determines how the product is supported, how evenly it moves through the steamer, and how effectively steam reaches every surface.

Get the belt wrong and the process compensates for it: longer cycle times, more rejected batches, higher energy use to force consistency the belt should have delivered on its own. Get it right, and residence time, product flow and cleaning performance stop being variables you have to manage manually.

Steam circulation and product exposure

Every product in a steaming line needs the same thing: the right heat and moisture, for the right amount of time, delivered consistently. When belt speed, product spacing or steam distribution is inconsistent, the belt is usually where the inconsistency started.

An open metal conveyor belt structure lets steam move around and through the product zone instead of stopping at the belt surface. That is the difference between a belt that transports product and a belt that becomes part of the process.

The right structure depends on the product. Delicate products need a stable, supportive surface. Heavier products need strength and rigidity. High-moisture products need aggressive drainage and easy cleanability. Twentebelt matches belt type, mesh opening, wire diameter and belt geometry to what the product actually needs, not to a standard catalogue size.

Conveyor belt behaviour in humid, high-temperature environments

Steaming environments punish weak engineering. Belts run under heat, moisture, condensation and repeated cleaning cycles, all while moving continuously. A belt that isn’t built for that will show it fast: tracking problems, corrosion, drift in dimensional stability.

Our conveyor belts are built to stay dimensionally stable under those conditions, resist corrosion, and keep moving predictably even as temperature and moisture fluctuate through the cycle. That reliability is the actual product. The belt itself is just the delivery mechanism.

Hygienic design for food processing

In food-grade steaming, hygiene isn’t a checkbox, it’s a production constraint. A belt that traps residue costs you cleaning time today and food safety risk tomorrow.

The open structure of a metal conveyor belt lets water, cleaning agents and steam pass straight through instead of pooling on top. That shortens cleaning cycles and reduces the chance of build-up becoming a contamination risk. For food processors, hygienic belt performance is a food safety requirement, and it’s also an uptime number: fewer minutes lost to cleaning is more minutes running.

Stable product handling during steaming

Products don’t stay the same during steaming. Texture softens, moisture content rises, weight distribution shifts. That makes product handling in a steamer more sensitive than in a standard transport application.

The belt has to hold a balance between open and supportive. Too open, and the product loses stability or deforms. Too closed, and you choke steam circulation and drainage. Twentebelt configures belts around that exact trade-off, whether the line runs vegetables, potatoes, pasta, meat, poultry, fish, dairy or bakery products.

Spiral and linear steaming systems

Not every steaming system is built the same way. Spiral configurations pack a long process time into a small footprint. Linear or tunnel systems spread the same process across defined zones, with more emphasis on product spacing, transfer points and drainage.

Each layout makes different demands on the belt. Spiral systems need stable tracking and a drive concept that doesn’t fight the belt. Linear systems need clean transfer points and consistent support across a longer run.

Twentebelt has three belt types built for exactly this range of steaming layouts:
• TwenteSideFlex — an external direct drive belt for spiral or oval systems without a central drum, built for layouts where flexibility and footprint matter.
• TwenteFlex spiral belts — a spiral belt built without welded connections, which removes one of the most common failure points in spiral steamers.
• Eyelink belts — a robust, permeable, flat-surface belt for steaming lines where product load and stable positioning matter most.

Choosing the right conveyor belt for steaming

There is no universal belt for every steaming line. The right one comes out of how product, process and system interact, not from picking the biggest or most expensive option.

Factors that actually decide it:
• Product type, weight and shape
• Required steam exposure and residence time
• Belt speed
• System layout: spiral or linear
• Cleaning procedure and frequency
• Operating temperature and moisture levels
• Transfer points and required open area
• Product support requirements

Twentebelt works through these factors with you before recommending a belt, not after.

TwenteSideFlex for steaming applications

TwenteSideFlex fits spiral or oval steaming systems where layout flexibility and reliable product handling matter, especially in systems without a central drum driving the belt. It holds stable movement through curved layouts and adapts to dairy, vegetable, potato, pasta, meat, poultry and fish applications that need controlled steam exposure.

TwenteFlex spiral belts for steaming applications

TwenteFlex is built for steaming processes that need long process times inside a compact footprint. Removing welded connections from the design removes one of the most common causes of spiral belt failure, which means more stable movement and fewer unplanned stops under humid, high-temperature conditions. TwenteFlex runs in low tension and direct drive spiral configurations across bakery, dairy, meat, poultry, fish, pasta, noodle and potato processing.

Eyelink belts for steaming applications

Eyelink combines strength, permeability and a flat conveying surface, which matters most when a product needs stable support and unobstructed steam, air or liquid flow at the same time. The open structure drains and cleans efficiently, while the flat surface keeps product positioning consistent through the process. Eyelink runs in steaming lines for vegetables, potatoes, meat, poultry, fish, dairy products and beverages.

Engineered conveyor belt solutions for controlled steaming

A steaming process is not just a temperature setting. Steam distribution, moisture control, product support, belt speed and system layout all decide the outcome, and the conveyor belt is where those factors meet.

Twentebelt has been engineering metal conveyor belts for over 100 years. That experience is what lets us match belt design to product behaviour instead of guessing and adjusting after installation. Machine builders and end users work with us because the belt is configured before it’s built, not fixed afterward.

It starts with a conversation about your product, process and layout. We are Twentebelt, and we’d be glad to have that conversation.
