Spray nozzles in agri-processing: Precision, efficiency and food safety
SPRAY nozzles from Spraying Systems Co., a leading manufacturer of spray technology, play a pivotal role in agri-processing, which involves transforming raw agricultural products into finished goods like dairy, bakery items, meat, beverages, and pet food.
These nozzles are engineered for precision, efficiency, and compliance with food safety standards, enabling operations such as coating, cleaning, sanitising, lubricating, humidification, and spray drying. By producing controlled droplet sizes and spray patterns—ranging from fine mist spray to full cone nozzles—they minimise waste, reduce chemical usage, and enhance product quality in processing plants.
In coating applications, spray nozzles ensure uniform application of ingredients to agricultural products. For instance, in bakery processing derived from grains, nozzles apply release agents and mould inhibitors to prevent sticking and extend shelf life, using Precision Spray Control technology for consistent coverage even on viscous substances like glazes or oils.
In pet food production from agricultural byproducts, they precisely dispense flavourings and antioxidants, improving palatability and consistency while cutting costs. For meat and poultry from livestock, antimicrobial agents are sprayed to inhibit bacterial growth, maintaining safety and freshness during processing.
Nozzles like the PulsaJet automatic spray guns adjust to line speeds, ensuring even coating of glazing liquids or chocolate enrobing on nuts and fruits, reducing over-application and waste.
Cleaning and sanitising are critical in agri-processing to prevent contamination. TankJet nozzles, for example, are used in dairy plants for thorough tank washing, removing residues from milk processing tanks while conserving water and chemicals. In breweries and wineries, automated systems sanitise hard-to-reach areas, shortening cleaning cycles and enhancing hygiene. The AutoJet Food Safety System has achieved up to 75% reduction in antimicrobial use in meat processing by optimising spray patterns for effective pathogen control. For fruits and vegetables, nozzles facilitate rinsing and washing lines, removing dirt and pesticides post-harvest on product, conveyors and crates.
Spray drying, a key process for powdered products from agri-sources, relies on SprayDry nozzles to atomize liquids into fine droplets for rapid evaporation.
These are essential for producing milk powder, whey, infant formula, coffee, spices, and yeast, handling high-viscosity feeds while maximising yield and particle uniformity.
In beverage processing, nozzles lubricate conveyors for smooth transport of bottles or cans filled with juices or beers from fruits and grains.
Humidification applications maintain optimal moisture levels in storage facilities for grains, fruits, and vegetables, preventing spoilage. Overall, these nozzles use
AutoJet spray controller for real-time adjustments, promoting sustainability by lowering water and energy consumption—critical in resource-intensive agri-processing.
The benefits include improved efficiency, cost savings, and adherence to food safety regulations like FDA standards, making Spraying Systems Co.’s. products indispensable for modern agri-processing operations.
