In the highly competitive beverage industry across New Zealand, operational efficiency and product quality are non–non-negotiable. From sparkling soft drinks to chilled craft beers, every can or bottle that rolls off the production line must be dry, clean and ready for filling and labelling. At SNE, we recommend Silvent’s Swedish‑engineered air nozzles and air knives—designed to meet stringent OSHA and EU Machine Directive standards—as the ideal solution for blow‑off, drying and cleaning applications on beverage lines.
Why Compressed‑Air Drying Matters in Beverage Manufacturing
Traditional drying methods—open‑pipe blow‑offs, inefficient nozzles or simple air hoses—waste energy, generate excessive noise and produce inconsistent results. In high‑speed canning lines, even a small amount of residual moisture can interfere with labelling adhesives, promote microbial growth or lead to packaging defects. By contrast, precision‑engineered air nozzles and air knives focus a ribbon or sheet of high‑velocity air exactly where you need it, removing moisture swiftly and uniformly without wasting compressed air.
Silvent’s Engineering Excellence: Made in Sweden
Silvent has built its reputation on rigorous design, testing and quality control. All products are manufactured in Sweden under ISO 9001 quality management systems and comply with:
-
OSHA 29 CFR 1910.242(b) for safe compressed‑air use, ensuring outlet pressures remain within non–hazardous limits.
-
EU Machinery Directive 2006/42/EC, guarantees that each nozzle and knife incorporates assessed risk‑reduction measures and CE marking for safe integration into automated machinery.
Every Silvent nozzle and air knife is made from corrosion‑resistant stainless steel or high‑grade aluminium, with a UV–stable polymer coating option for harsh wash‑down environments. This longevity means replacement intervals measured in years, not months—critical in 24/7 beverage plants where unplanned downtime can translate into thousands of dollars lost per hour.
Key Benefits for Beverage Lines
-
Up to 70 % Lower Compressed‑Air Consumption
Through Bernoulli‑principle designs and precision‑machining, Silvent nozzles entrain ambient air efficiently, amplifying the blown‑off air volume without drawing more compressor power. On a single canning line, this can translate into significant kW‑hour savings and reduced load on central air systems. -
Noise Reduction for OSHA Compliance
Open‑pipe blow‑offs commonly exceed 100 dB(A), requiring extensive hearing protection programs. Silvent’s nozzles and knives operate at less than 80 dB(A) in most setups, dramatically lowering background noise, improving operator safety and potentially reducing hearing‑protection costs. -
Consistent, Uniform Drying
Whether mounted above a conveyor for top‑of‑can blow‑off or arrayed inside a rotating drum for internal moisture removal, Silvent air knives deliver a laminar airflow that blankets every surface. The result is complete drying—even in recessed can threads and under lip seals—eliminating rejects and rework. -
Rapid ROI and Lean‑Manufacturing Impact
Reduced energy consumption and noise levels free up compressed‑air capacity for other pneumatic equipment (e.g., filling valves, labelling heads), supporting continuous‑improvement initiatives. The long service life of Silvent components also minimizes spare parts inventory and maintenance labour, driving leaner operations.
Typical Beverage‑Industry Deployments
-
Pre‑Fill Can Drying: A series of angled air knives above the infeed conveyor blasts off cleaning solution and rinse water, ensuring each can enter the filler bone‑dry.
-
Post‑Fill Cap and Label Zone: Targeted nozzles remove condensation that forms after pasteurization tunnels or carbonated fillers, preventing label lift and promoting adhesion.
-
Rinse‑Water Removal in Re‑Wash Loops: In plants that recirculate cleaning fluids, high‑velocity nozzles inside flip‑over stations remove droplets before cans re‑enter the wash cycle, reducing fluid carry‑through and chemical use.
