Spray Controllers - Advanced Spray Control
 AutoJet
Modular Spray Systems with Model 2250 Spray Controllers provide
real-time control of spray processes. Patented SprayLogic®
software allows the controllers to accurately monitor and automatically
adjust spray performance based on what’s happening in your
process.
Features
include:
- User-friendly
interface
- System
status is shown on an easy-to-read LCD display
- Keypad
with “smart keys” allows for easy menu navigation
and data entry
- Advanced
timing control
- Object
detection sensors can supply start and stop trigger signals
- On/off,
delay parameters easily set; spray duration as low as one
millisecond
- Pulse
Width Modulated Flow
- Advanced
flow sensing and spray shaping
- Monitors
liquid flow and other performance criteria with automatic
shutdown
on selected faults
- Accurately
detects nozzle wear and blockage — even partial plugging
- Adapts
flow rates and spray patterns to the shape of the product
being sprayed with variable shape spray control algorithms
- Improves
system troubleshooting with intelligent fault messages
- Open-loop
or closed-loop spray control
- Optimizes
spray performance with cascaded control loops and multiple
PID regulation
- Maintains
constant flow rate or spray pressure
- Maintains
constant application rate on a variable speed conveyor
- Maintains
constant temperature when cooling gases or solids
- Provides
multiple combinations of pressure settings for convenient
batch control
AutoJet
Modular Spray Systems with the Model 2250 Spray Controller are ideal
for spray applications where automatic adjustment is necessary with
validated results.
Typical
Applications
Spraying
Antimicrobials
Problem:
A leading meat processor uses an antimicrobial agent to extend the
shelf life of its meat products. Activating the spray nozzles to
hit the moving trays was difficult, and with variable line speeds,
they were unable to apply a consistent coating on every meat tray
on the conveyor. Product quality and overspray of the costly solution
were major concerns.
Solution:
An AutoJet Modular Spray System ensures that the correct amount
of ascorbic acid is applied to the meat products every time despite
varying line speed. The spray controller manages the timing of two
automatic spray nozzles based on the speed of the conveyor. Optical
sensors are used to detect the meat trays as they pass below the
spray nozzles, eliminating overspray on the conveyor. The AutoJet
Modular Spray System provides annual savings of more than $50,000
by reducing the consumption of ascorbic acid and the scrap caused
by packaging problems.
Topical
Coating of Tissue and Paper
Problem:
A manufacturer of paper products needed to apply a perfume on tissue
paper, paper towels and hygienic paper products without wetting
the paper. Previous spray systems could not properly adjust the
spray for varying line speeds and stained the product with excessive
perfume.
Solution:
An AutoJet Modular Spray System equipped with a Model 2250 AutoJet
Spray Controller triggers automatic spray nozzles and automatically
adjusts the flow rate based on line speed. The uniform perfume coverage
provided by the Modular Spray System improved product quality, reduced
scrap and decreased maintenance downtime.
