As a food and beverage producer, you are striving for consis-

tent quality regardless of where your product is manufactured

or distributed. You’re also faced with the challenge to respond

more quickly than your competition to changes in consumer

demand. At the same time, your industry requires global com-

patibility, consolidation of suppliers, and compliance with new

regulations for operations.

At Thomas & Betts, we understand the food and beverage

processing industry and the challenges faced by its electricians.

We’re focusing on products designed to address issues in every

phase of your operation so you can focus on cost, quality, flex-

ibility and regulatory challenges across the production cycle —

from raw materials through delivery.

Our expertise in inventive engineering and manufacturing new

products will help you make best use of the valuable

human, physical and financial resources in your plant.

Reliability

Thomas & Betts is the time-tested leader in electrical compo-

nents for food and beverage operations by offering:

to provide consistent quality and safety in our products.

Cost Savings

With the spotlight on total manufacturing costs, quality of

material or workmanship is quickly being identified and cor-

rected through new specifications. Today’s total quality environ-

ment is pinpointing production costs, even down to the level of

a cable tie. T&B delivers significant reductions in your Total Cost

of Ownership (TCO) and has established a reputation for:

with fewer call-backs.

on-time delivery and competitive pricing.

Flexibility

Newer, high-speed packaging equipment may make the

difference in profit in your plant, and at the same time may

require the greatest change in your distribution wiring - in half

the time it took a few years ago. Today’s electrical system will

likely contain components from several foreign manufacturers,

requiring global compatibility in material performance, ease of

installation and continued maintenance to ensure maximum

return on investment. Thomas & Betts will ease the transitions in

your facility through:

The following pages offer an outline of chemical considerations

for caustic chemical washdown settings and a brief

explanation of applicable products compatible with food and

beverage processing plants.

Harsh Chemical Environments

Many chemicals are frequently used in the processing of red meats. Some chemicals will not damage metal equipment or most painted surfaces when used as directed, while others may require stainless steel materials for safe use.

Phosphoric Acid is used to remove milk stone from dairy processing pipes and equipment and removes mineral deposits. This USDA-approved chemical requires stainless steel materials for optimum performance.

The Environment

Type of Cleaner Chemicals Purpose of Cleaner

Acid Cleaners - High Foaming

Phosphoric Acid High-foaming, non-fuming acid cleaner for scale removal and brightening of aluminum, galvanized metal, and stainless steel equipment. Will not damage metal equipment or most painted surfaces when used as directed. Contains no harsh hydrochloric, sulfuric components.

Acid Peroxygem Sanitizers Hydrogen Peroxide, Acetic Acid (ethanoic acid, vinegar acid), Peroxyacetic Acid (and acetyl hydroperoxide)

A concentrated, no rinse, non-foaming acidic peroxygen sanitizer. Contains no chlorine. Safer for the environment while being less harmful to equipment. Quickly kills a broad spectrum of microorganisms. Effective over a wide range of pH. USDA applicable.

Chlorine Sanitizers Sodium Dichloro-s-Triazinetrione, Dihydrate, Sodium Dichlorocy-anurate Dihydrate, Monosodium Phosphate, Anhydrous Sodium Sulfate, Sulfuric Acid Disodium Salt

For use in preparing no-rinse sanitizer solutions in food processing plants. Readily soluble in cold water. Leaves no film on surfaces. Can also be used to sanitize hatch-ing eggs in the poultry industry. USDA applicable, EPA registered.

Denaturants Nonylphenoxy Poly (ethylenoxy) ethanol

This product is formulated to denature condemned car-casses and meat or meat products in red meat processing plants. Thus denatured, the meat can be disposed of as tankage. This product will impart a green color as well as a strong citronella odor to meat.

Food and Dairy Products - Heavy Duty Low Foam Cleaner

Sodium Hydroxide, Sodium Carbonate

Used for C.I.P. cleaning operations. Contains strong alkalis to remove soil that is encountered in processing lines. Hard water tolerant and free- rinsing. Safe for use in all food processing facilities. USDA applicable.

Dairy - Milk Stone Remover

Phosphoric Acid Used for removal of milk stone from dairy processing pipes and equipment. Removes mineral deposits. Harmless to stainless steel equipment. Low foaming for proper flow through pipes. For manual and circulation-type cleaning operations. USDA ap-plicable.

Poultry Floor Cleaner Sodium Metasilicate, Trisodium Or-thophophate, Sodium Carbonate, Sodium Chloride, Nonylphenoxy-poly Ethanol

Used for heavy duty cleaning in poultry plants. General cleaner. Removes blood, grease and waste deposits. Use manually or with mechanical floor scrubber. USDA applicable.

Floor Cleaner Diethyleane Glycol Monometh-ylether, Sodium Dodecylbenzene Sulfonate, Sodium Silicate

Used to remove dirt, food, grease, fats and soap scum. Can be used on concrete, masonry, brick, stone, and ceramic tile. Has moderate foam to promote free rinsing with no residue. USDA applicable.

Washdown settings demand the highest performance

electrical components for power distribution to equipment,

devices, switches, appliances and lighting systems. Washdown

procedures demand connections capable of exceeding direct

infiltrated with water or becoming disengaged during the water

blast. Additionally, it is of vital importance that all connections

used in washdown areas are resistant to corrosion or rust due to

any residual or standing water remaining even after blowdown

operations.

Water and corrosion from water are some of the highest threats

to safe and reliable connections in food and beverage manufac-

turing. The estimated cost of corrosion to the food processing

industry alone exceeds $2.1 billion annually, not including labor

and downtime involved in equipment failure.

Cleaning is one of the most important aspects of any food

cleaning efforts, many packaging machine manufacturers de-

it is highly recommended for components necessary to power

environments, from accidentally entering food products during

Additionally, there are important safety steps taken to prevent

foreign objects from falling into open vats or grinding systems.

Many plants have banned personnel from using ordinary main-

tenance supplies or carrying personal items that can pass un-

noticed through metal detectors, x-ray equipment and standard

visual detection systems. Those responsible for managing safety
