Spraying Systems New Zealand


With more than 79 years of experience in the meat processing industry, Spraying Systems New Zealand has the experience and the know-how to provide spray technology solutions for a wide variety of applications. Over the years, we have been able to forge long-lasting relationships with our customers who have come to rely on us as their single source supplier for all their spray technology needs.

One of the most important issues addressed daily in meat processing plants is that of food safety. We are seeing an increased focus on measures used to ensure the highest levels of food safety in processing plants that include applying antimicrobials directly to meat products and/or packaging, as well as applying sanitisers on surrounding conveyors and tables.

Making sure the exact dose of antimicrobial used is also very important as over-application and under-application is not effective.

AutoJet® Food Safety Systems have been proven to effectively control pathogens such as E.coli, Salmonella and Listeria monocytogenes, and can be incorporated into existing HACCP plans. The multi-purpose systems can be used for applying antimicrobials into vacuum packages before meat is inserted, onto roll stock products and on the surface of fresh meats. They can also be used for applying sanitisers on conveyors, in grinders and on high-speed slicing equipment.

AutoJet Food Safety Spray Systems utilise Precision Spray Control (PSC) which allows for the precise application of antimicrobials and sanitisers directly to the target, ensuring consistent performance with minimal waste. The systems typically consist of an AutoJet Spray Controller and PulsaJet® spray nozzles fitted with UniJet® spray tips in food-grade compliant materials. The spray nozzles minimise the need to change spray set-ups between batches, as the nozzles are capable of producing a wide range of flow rates. Added benefits of using the AutoJet Food Safety System include an increase in production, minimised risk of contamination, increased shelf life of products and a reduction in operating costs.

In addition to food safety systems, we also have systems designed specifically for spray chilling, humidification and cleaning evisceration tables in abattoirs. The common practice for cooling carcasses after being slaughtered is to circulate cold, dry fan-forced refrigerated air over the carcasses. This process draws moisture from the meat, which leads to shrinkage and a typical carcass weight loss of 1.5 to 2%.

The Spraying Systems solution takes a different approach. The AutoJet® Carcass Chilling Spray System uses a range of spray nozzles to successfully offset the evaporative loss during the carcass chilling process. The PLC used by the system accurately monitors the timing and the amount of water sprayed between cycles in order to minimise the shrinkage to as close to zero as possible.

The system has been shown to reduce the total loss of carcass weight to 0.5% or less, which can lead to savings of thousands of dollars per year. Additional advantages include savings on energy and refrigeration expenses and a reduction in cleaning time. The AutoJet Carcass Chilling Spray System has been successfully implemented in several lamb, beef, sheep, venison and pork processing plants.

Meat processing plants that require control of the relative humidity in their fogging rooms to prevent potential weight loss of their cut meat products can benefit greatly from our humidification systems. The main component is the compact and lightweight MiniFogger® III which is suitable for installation on walls, ceilings and in corners as you have the option of using one to four spray setups on the unit.

The unit can also assist in preventing possible OH&S issues such as slippery floors due to the ultra-fine mist that does not leave floors or surrounding areas wet. The MiniFogger III produces very small drops in the .7-12 micron range for fast evaporation. Advantages of using the unit for humidification operations include consistent misting, automatic spray alignment of the spray nozzles and an overall energy efficient operation.

For the cleaning of evisceration tables, processors will typically mount spray bars across the conveyor belt to wash and sanitise the tables. This process can lead to using larger amounts of water than required, and can create overspray problems if the spray bar has not been sized correctly. We have developed the AutoJet® Evisceration Table Cleaning System which is able to achieve a more efficient, reliable and economical clean compared to other solutions available in the market today.


The system uses hot water sprayed through three YNRAJ rotating arms. The arms cover the width of the belt, which allows for the entire surface of the table to be washed. Water usage is reduced by up to 40% as the rotating arms operate at a lower total flow rate when compared to a traditional spray bar, as fewer nozzles are required.


We have many more solutions for cleaning equipment and conveyors in meat and poultry processing plants. The stainless steel version GunJet® CU150A-316 spray gun features an ergonomic design to reduce operator fatigue, and is available in a choice of three spray capacities: 38, 61 and 83 litres per minute. The spray pattern can be easily adjusted from a solid stream to a 50° hollow cone by varying the pull of the trigger.

Alternatively, the high impact, low pressure FlatJet® spray nozzles are an ideal solution for cleaning conveyors. The nozzles are very effective for cleaning at low pressures ranging from 1 to 10 bar. The high impact spray removes debris, while the low pressure prevents contamination of surrounding areas. The overlapping spray pattern ensures that all areas of the conveyor are covered and cleaned properly.
