Metal conveyor belts for food processing and industrial lines
Tell us what your line does and we build the belt to match it. Below are the processes YIYI Mesh Belt supplies most often, what the belt does in each one, and the belt types buyers usually ask for.
Freezing, cooling, baking, frying, coating, pasteurizing, meat and seafood, washing and spiral ovens.
F1 · FOOD
Freezing & IQF
In a spiral freezer or IQF tunnel freezer, the belt carries raw and cooked products through cold air for hours without stopping. An open stainless steel spiral freezer belt lets the cold air pass through the product from below, keeps the belt running flat around the drum and tolerates repeated wash-down.
Bread, buns and pastries go into a spiral cooler or spiral proofer straight after the oven or before baking. The spiral cooling conveyor belt gives a stable, open surface so dough and baked goods cool or rise evenly, and turns the same radius as the existing drum.
In a tunnel oven the baking conveyor belt carries pizza, pies, biscuits and bread through hot zones. A stainless steel oven belt with the right mesh opening supports the product, lets heat reach the base and keeps the belt tracking straight at high temperature.
A fryer conveyor belt moves donuts, snacks and coated products through hot oil. The open wire mesh fryer belt drains oil fast, holds small pieces securely and runs with side chains or flights where the product must be pushed under the oil.
On an enrober, the enrober wire belt carries biscuits, bars and confectionery through a curtain of chocolate or coating. A fine, flat chocolate enrobing belt lets the excess coating drip back and releases the product cleanly at the transfer.
A blancher or pasteurizer conveyor belt carries vegetables, packed products or jars through hot water or steam. The stainless steel mesh belt lets water and steam reach every side of the product and stands up to constant wet heat.
From forming and marinating to cooking and freezing, a meat processing conveyor belt carries patties, chicken parts and shrimp. An open stainless steel conveyor belt for poultry and seafood drains liquids, is easy to clean and keeps the product flat for the next step.
A washing conveyor belt moves fruit, vegetables and parts under spray bars, then through a dryer. The open dryer mesh belt lets water drain away and hot air flow through the product, so it leaves the line clean and dry.
A spiral oven cooks chicken, meat, ready meals and bakery products on a long belt path in a small footprint. The spiral oven belt must turn around the drum at cooking temperature, stay flat under load and carry the product evenly through steam and hot air, cycle after cycle.

Heat Treatment & Furnaces
In a mesh belt furnace for hardening, tempering, annealing or sintering, the high temperature conveyor belt carries metal parts through the hot zone. Heat-resistant alloy wire and a dense weave keep small parts on the belt and the belt stable under load and heat.
In a glass annealing lehr, the lehr belt carries bottles, jars and tableware slowly from hot to cool. A flat, stable glass annealing conveyor belt keeps the glass upright and transfers it smoothly to the cold end.
A can washer belt carries empty cans upside down through washing, rinsing and drying zones. The open stainless steel can washer conveyor belt lets spray water pass through, resists chemicals and keeps cans moving in neat rows.
Where loads are heavy or the line is long, a chain driven wire mesh belt or plate link conveyor belt takes the pulling force on its side chains. The mesh or plate carries the product, the chains carry the load, so the belt keeps its shape for longer.
Screws, stampings and electronic parts need a fine mesh conveyor belt that will not let them slip through. A tightly woven small parts conveyor belt gives a flat, stable surface for cleaning, drying, heating or inspection.
In a brazing furnace — controlled-atmosphere aluminium brazing for heat exchangers, or copper brazing of steel parts — the brazing furnace belt carries assemblies through the hot zone and cooling section. A flat, heat-resistant mesh belt for brazing furnaces keeps parts level so joints form evenly, and holds its shape over long runs at temperature.
Questions buyers ask us about belts for each application.
Freezing & IQF
Which belt is used in a spiral freezer?
Most spiral freezers run a stainless steel spiral belt with collapsible links on the inner edge, so the belt can turn around the drum. A small radius spiral belt is used when the drum is small or the freezer needs a tighter turn. Send us the drum diameter, belt width and tier pitch and we match the belt to your freezer.
Can you make a replacement belt for an existing spiral freezer?
Yes. We work from your old belt sample, drawing or measured data — pitch, rod and link dimensions, width and turning direction — and confirm a drawing with you before production.
Cooling & Proofing
What is the difference between a spiral cooling belt and a spiral freezer belt?
The belt construction is similar; the duty is different. A cooling or proofing spiral runs warmer and the product is softer, so mesh opening and surface support matter more. We check product size, weight and temperature before recommending the mesh.
Which belt suits bread and buns after the oven?
A spiral belt or an eye link belt with an open mesh that lets air pass under the product. Tell us the product size and the conveyor or drum data and we propose the belt.
Baking
Which conveyor belt is used in a tunnel oven?
Balanced weave and trapezoidal mesh belts are common in tunnel ovens. The choice depends on product size, how much support the base needs and the oven temperature. Chain driven belts are used where the oven drives the belt by side chains.
What data do you need to quote an oven belt?
Belt width and length, oven temperature, product type and size, drive type (friction or chain) and the mesh you use today. A photo or sample of the old belt helps us match it.
Frying & Snacks
Which belt is used in an industrial fryer?
An open balanced weave or flat wire belt drains oil quickly. Fryers that push the product under the oil often use a chain driven belt with flights.
Can you add flights or side guards to a fryer belt?
Yes. Flights, side plates and chain edges are built to your drawing. Send the fryer model or drawing and the product you fry.
Coating & Chocolate
Which belt is used on a chocolate enrober?
A fine, flat wire mesh belt that lets coating drip through and releases the product cleanly. Send us the enrober width, mesh you use today and the product so we can match it.
Do you make enrober belts to replace an existing belt?
Yes. We work from your old belt sample or measured data and confirm a drawing before production.
Blanching & Pasteurizing
Which belt is used in a blancher or pasteurizer?
An open stainless steel mesh belt — balanced weave, eye link or chain driven — lets water and steam reach every side of the product. The choice depends on product size and how the machine drives the belt.
What information do you need for a pasteurizer belt?
Belt width and length, water or steam temperature, product and load, drive type, and the belt you use today.
Meat, Poultry & Seafood
Which belt is used for meat, poultry and seafood processing?
Flat wire, eye link and spiral belts are the most common. They drain liquids, are easy to clean and keep the product flat for forming, cooking or freezing.
Can the same belt run through cooking and freezing?
It depends on the line. Many plants use different belts for each step. Send us the process flow and temperatures and we recommend the belt for each section.
Washing & Drying
Which belt is used in a washing machine or dryer?
An open balanced weave or eye link belt lets water drain and hot air pass through the product. Chain driven belts are used for heavier loads or long dryers.
Can you supply belts for vegetable and fruit washing lines?
Yes. Send us the machine width, product and drive type and we propose the mesh opening and wire size.
Spiral Oven Cooking
Which belt is used in a spiral oven?
Spiral ovens run spiral belts that turn around the drum at cooking temperature. A small radius spiral belt is chosen when the oven drum is compact. Wire, links and mesh are selected for the oven temperature and product load.
What data do you need for a spiral oven belt?
Drum diameter, belt width, tier pitch, number of tiers, turning direction, oven temperature and product. A sample or drawing of the current belt helps.
Heat Treatment & Furnaces
Which belt is used in a mesh belt furnace?
A balanced weave or compound weave belt made from heat-resistant wire. Dense weaves keep small parts on the belt; chain driven belts are used for heavy loads.
How do you choose the wire material for a furnace belt?
By working temperature, furnace atmosphere and load. Send us these data and the belt you use today, and we confirm the material and weave with you.
Glass Annealing
Which belt is used in a glass annealing lehr?
A flat, stable balanced weave belt or a chain driven belt carries the glass from the hot end to the cold end without tipping it.
What data do you need for a lehr belt?
Lehr width and length, temperature profile, product type and the belt you use today.
Can Washing
Which belt is used in a can washer?
An open stainless steel balanced weave or eye link belt lets spray water pass through and keeps cans in rows.
Can you replace the belt on an existing can washer?
Yes. Send us the old belt data or sample, machine width and drive details, and we confirm a drawing before production.
Heavy-Duty Conveying
When should I use a chain driven belt or a plate link belt?
When the load is heavy or the conveyor is long. Side chains take the pulling force, so the mesh or plate only carries the product.
Can plate link belts be perforated?
Yes. Plates can be plain or perforated, with flights or side guards to your drawing.
Small Parts & Electronics
Which belt is used for small parts and electronics?
A compound weave or dense balanced weave belt with a small mesh opening, so small parts do not fall through.
How do you choose the mesh opening for small parts?
From the smallest part size and weight. Send us part dimensions and the process — cleaning, drying, heating or inspection.
Brazing Furnaces
Which belt is used in a brazing furnace?
A flat balanced weave or compound weave belt made from heat-resistant wire, chosen for the furnace temperature and atmosphere so parts stay level through the hot zone.
What data do you need for a brazing furnace belt?
Furnace type (controlled atmosphere or other), working temperature, belt width and length, part weight and the belt you use today.
