Meat Processor Saves
Precision spray control system accelerates corporate sustainability initiative & saves meat processor US$394,000 annually
Problem:
A major beef processor needed a better way to apply a proprietary shelf life extender to sliced products in a tray pack prior to film wrapping. In-house engineering staff had developed a spray system equipped with photooptic sensors to determine the presence of a tray pack. A pneumatic solenoid was used to turn the spray nozzles on to apply the ingredient.
Timing adjustments had to made by maintenance staff rather than line operators and resulted in unproductive downtime. Inaccurate sensors and slow solenoid activation of nozzles caused inconsistent application of the shelflife extender and significant overspray, which negatively affected tray pack handling. Nozzles also plugged frequently, causing another maintenance headache. Finally, the rinsing system added to wash excess coating from conveyors operated 24/7 and hindered an important corporate sustainability initiative.
Solution:
We recommended an AutoJet® Spray System equipped with a Model 1550+ spray controller and a PulsaJet® electrically-actuated spray nozzle triggered by a laser sensor. Using a nozzle with a larger orifice
has solved the plugging problems. Capable of cycling up to 10,000 times per minute, the PulsaJet nozzle’s exceptionally fast operation and positive shut-off has nearly eliminated overspray, reduced ingredient
consumption and enabled the plant to completely turn off the rinsing system.
