place (FIP) system, tanks for storing gray water and a
Dosatron that injects chemicals and provides automatically
timed turbulent flow to help extend the life in between
deep cleaning.
" We have options like mist collection - a vacuum system
with filters that sits off to the side and connects to the
downstream hood and collects the atomized airborne particulates
that can get on surfaces around the system, " Mr.
Miller said. " It's pretty standard for most bakeries because
anytime you're atomizing and spraying through a nozzle,
you're going to have airborne mist. Additionally, our vision
system allows us to spot spray so there's less mist, less
product waste and less quality concerns that are a result of
spraying empty pockets. We're using cone sprays that are
targeted and not spraying when product isn't present. "

topping applicators that include vision technology coupled
with high-speed nozzle activation to apply viscous
materials and large particulates. Mr. Murphy said the
menu-driven systems include improved clean-in-place
(CIP) capabilities that reduce waste during changeovers.
" This freeform vision technology allows for changeovers
on the fly for changes of the shape and size of the
item being topped, " he said. " For changes in the topping
material, the CIP features allow for quick cleaning of the
system with minimal disassembly or risk of losing parts. "
AMF Tromp offers updated systems for dry, frozen
and moist ingredients. Mr. Besems said the waterfall
applicator for high-capacity toppings offers a belt-wide
strewing bed, and unused ingredients are recycled continuously
until a changeover or cleaning cycle. The target
applicator provides specific placement of toppings
onto crusts and flatbreads beneath the system. He added
the Smart Applicator uses AI and machine-learning to
make these machines even better.
" Digital images of the product are analyzed in real
time, and settings on the applicator change immediately
to ensure optimal product quality and consistency, " Mr.
Besems explained. " Eliminating waste and improving
product quality with each production run with less operator
intervention needed are benefits. "
Finishing with a flair
Sanitation and accuracy are key issues when applying a
nice sheen on buns and pastries during the glazing process.
Often egg wash is used, but many bakeries have turned
to non-egg alternatives to provide that shine on brioche.
However, several of these alternatives require careful cleaning
processes and mist control to prevent nearby equipment
from getting a sticky surface.
At IBIE 2022, Burford offered its third generation of

generation Variable Profile Liquid Spray (VPLS) system at
the recent Baking Expo. The VPLS sprayer provides greater
accuracy, reliability and ease of sanitation.
" GOE is using flow meters in critical applications to
monitor, alarm and control the application rate on products, "
said Norm Searle, sales and marketing, GOE/
Amherst Stainless Fabrication. " These devices allow us to
maintain exact delivery rates and compensate for changes
in temperature and viscosity. "
Mr. Searle said a primary objective is to accurately deliver
the spray with cross-the-band consistency to ensure
acceptable finishing, reduce ingredient consumption
and ensure the glazing meets labeling requirements on
the package.
" In a perfect world, delivery of each ingredient would
be exact, " he said. " In reality, various factors limit absolute
accuracy. As technology advances, opportunities become
available to improve accuracy either from material advances,
electrical/electronic/software developments - or both. "
Bob Peck, vice president of engineering, E.T. Oakes,
pointed out that PLCs combined with servo motors have
increased accuracy, repeatability and reliability over chaindriven
systems that require lubrication and maintenance.
" Variable-frequency drive motors or air-cylinders do
not produce highly repeatable deposits because of the fluctuation
of their operation and air pressure, " he explained.
" Servo motors provide closed-loop feedback. That means if
we instruct it from a PLC to provide 1,000 pulses on this
motor, we receive feedback that it actually provided 1,000
pulses. That's where the accuracy comes in. "
Mr. Peck said PLC systems can include diagnostic
screens to troubleshoot problem areas and test sensors, encoders
and other key components. Maintenance logs can be
included within the PLC program to schedule maintenance
and track machine-running hours for routine maintenance
requirements. Moreover, servos provide faster speeds.
