At Annilte, we specialize in designing and manufacturing durable, application-specific perforated conveyor belts that drive efficiency across industries from food processing to packaging and industrial manufacturing.

A perforated conveyor belt is a belt intentionally fabricated with a series of holes or apertures in a specific pattern and size. These are not “one-size-fits-all” products. The hole diameter, shape (round, square, slotted), and spacing (pitch) are critically engineered to perform a specific function within your system.

Why Choose a Perforated Belt?

Drainage & Liquid Removal:

• Application: Food processing (washing fruits/vegetables, fish processing), bottling plant rinse sections, wastewater treatment.
• How it works: Allows water, oils, or other liquids to pass through the belt, preventing pooling, improving hygiene, and keeping products dry for the next stage.
• Annilte Solution: We offer belts with optimized hole patterns to ensure fast, complete drainage without compromising belt strength.

Vacuum & Suction Holding:

• Application: Holding lightweight bags, sheets, or products on inclined conveyors; precise positioning in CNC routing or cutting machines; label application.
• How it works: A vacuum chamber under the perforated belt uses suction through the holes to firmly hold items flat and in place, even on steep inclines or at high speeds.
• Annilte Solution: Precision-engineered hole patterns ensure consistent vacuum distribution and reliable hold.

Airflow & Temperature Control:

• Application: Cooling baked goods, chocolates, or packaged products; drying painted or coated items; aerating products.
• How it works: Allows controlled air to pass through the product from above or below, enabling uniform and efficient cooling or drying, reducing process time.
• Annilte Solution: Custom perforation layouts to match your airflow requirements and ensure even exposure.

Sorting & Screening:

• Application: Separating small components or scraps (like in recycling), screening grains, de-dusting.
• How it works: Smaller particles or materials fall through the holes, effectively sorting them from larger items on the conveying line.
• Annilte Solution: Durable belts with wear-resistant edges and precise hole sizing for accurate separation.
