The power of auditing

The big chill

Operators know what they spend on electricity and other utilities. However most do not know how to scrutinize their operations to
make the most of their energy dollar. Having had the opportunity to
do several dozen plant audits over the past year, it is obvious that the
food industry will pay for sanitation, food safety and worker safety audits, but few seem to do energy audits. In fact, if one were to rank audits in order of importance, worker safety would be number one and
the energy audits at the bottom of list.
So, who can do energy audits? Two basic options are available:
local public utility companies or a consulting firm. For example, in
California, Pacific Gas and Electric offers not only consulting services, but also conducts classes designed to help users evaluate energy use and recommends savings programs. In other words, they
help processors conduct internal audits. PG & E even has an online
feature that allows its business customers to evaluate energy usage
and identifies savings opportunities.
According to the Process Design Center, Santa Barbara, Calif., "The
purpose of an energy audit is to identify cost-effective options to improve the energy efficiency of a specific facility." Consultants should
look at all aspects of your operation from things as mundane as office
lighting to operations as obvious as boiler efficiencies. The bottom line
is energy experts can help companies save energy and money.

One of the biggest energy expenditures for many plants is the cost
of refrigeration. Very few facilities do not have some kind of cold storage or freezer facilities. Any area that is to be used for refrigeration
must be designed properly. Walls and ceilings must be properly insulated, built tightly to maintain and conserve refrigeration and properly
maintained to ensure proper and efficient operation.
There are several areas where energy savings may be achieved
when running a cold storage facility:
* Automated power
* Compressor motor control
factor correction
* Floating head pressure
* Electronic evaporator
and pack control
control system
* Lighting
* Maintenance and monitoring
* Heat recovery
* Cold store door maintenance * Automatic non-condensable
* Use of cheap-rate electricity
gas purgers
* Refrigerated loading docks
* Selecting the right condenser
Automatic power correction ensures the plant uses electrical energy
efficiently. Electricity travels through lines in waves. Installing power factor
correction capacitors at the point where electrical lines enter a plant can
help ensure energy is adjusted to meet the demands in the plant.
Every refrigerator and freezer has one or more entries into the
cold storage areas. The type of door that is installed can have a significant impact on energy utilization. Each time a door is opened, the
cold storage area heats up slightly and additional energy must be expended to maintain the system. The goal is to keep the cold storage
area cold, not to heat your plant.
Installing well insulated doors that open and close quickly will help
ensure cold air stays where it belongs. Rapid roll-up doors raise and
lower within seconds and allow ease of access into and out of cold
storage rooms. Fork truck operators should have remote openers or
there should be pulls on both sides so they can get in and out. The
same should apply to loading refrigerated docks. Not only are good
doors are required, but processors and warehousemen need to
maintain the shipping bays. Bays in facilities with refrigerated loading
docks should have properly designed and maintained cushioning so
trucks literally form a seal with the building.
As part of an energy audit, some energy auditors utilize infrared scanning systems to determine areas in and around the facility where energy
is being lost. This type of scan can show where chilled air is seeping
from cold storage or refrigerated work areas or where heat is being lost
due to poor insulation. Pest control experts recommend that all doors
leading to food processing, handling and storage facilities be tightly
sealed to exclude pests. They also suggest that doors be self-closing to
ensure they remain closed. These same recommendations apply to energy savings. Tight-fitting doors minimize the loss of heat from buildings
or the flow of heat from entering rooms that are refrigerated. The savings
may not seem like much, but they add up over the course of a year.
A final way to save energy is, ironically, good sanitation practices.
Blowers and other components of cooling systems get dirty. They
need to be part of every company's master sanitation schedule. The
obvious goal is to protect products from potential contamination, but
proper cleaning can also save energy.

Illuminating opportunities
Light is essential for all operations. Regulations define how much
illumination should be cast over work areas. How a facility approaches lighting depends on a number of factors. These include the age of
the processing plant, whether it is owned or leased and production
volumes. Older facilities tend to be tougher to work with because they
were not designed with issues such as energy savings in mind.
An operation that runs only a day shift might consider renovating
the facility to take advantage of natural lighting, which would reduce
overall electricity costs. New plants are designed to use both natural
lighting and light colors, usually white, to ensure production floors are
bright and well lighted. It doesn't hurt that reinforced Plexiglas, which is
used frequently for walls and ceilings, is not only easily cleanable and
strong, but also is almost always white, and, hence reflects light well.
How managers light their plants also plays a role in utility costs.
Improved operating efficiencies may be achieved by using both metal halide and high-pressure sodium lamps. "Pulse-start" metal halide
lamps and compatible energy efficient ballasts provide users with reduced input watts and increased light output compared to standard
M.H. lamps. They also provide better color rendering and longer life.
Buyers should select or specify lighting with Luminaire Efficiency Ratings that meet the recommended levels, based on industry standard
tests. Processors should evaluate their needs and select accordingly.
Processors also have the option of installing smart systems. This
technology shuts down or dims lights in areas that are not being
used, such as offices, rest rooms and conference rooms. Facilities
that use natural lighting can also benefit from smart technologies.
Sensors can be used to dim or brighten lights to established luminosities ensuring that an area is maintained at the proper level.
