STAINLESS STEEL EQUIPMENT CARE

AND CLEANING

Contrary to popular belief, stainless steels ARE susceptible to rusting.

Corrosion on metals is everywhere. It is recognized quickly on iron and steel as unsightly yellow/orange rust. Such metals are called “active” because they actively corrode in a natural environment when their atoms combine with oxygen to form rust.

Stainless steels are passive metals because they contain other metals, like chromium, nickel and manganese, that stabilize the atoms. 400 series stainless steels are called ferritic, contain chromium, and are magnetic; 300 series stainless steels are called austenitic, containing chromium and nickel; and 200 series stainless, also austenitic, contains manganese, nitrogen and carbon. Austenitic types of stainless are not magnetic, and generally provide greater resistance to corrosion than ferritic types.

With 12 to 30% chromium, an invisible passive

lm covers the steel’s surface acting as a shield against corrosion. As long as the lm is intact

and not broken or contaminated, the metal is

passive and stainless. If the passive lm of

stainless steel has been broken, equipment starts to corrode and starts to rust.

Enemies of Stainless Steel

There are three basic things which can break

down stainless steel’s passivity layer and allow

corrosion to occur.

1. Mechanical abrasion.

Water comes out of the faucet in varying degrees of hardness. Depending on what part of the country you live in, you may have hard or soft water. Hard water may leave spots, and when heated leaves deposits behind that if left to sit, will break down the passive layer and rust stainless steel. Other deposits from food preparation and service must be properly removed.

Chlorides are found nearly everywhere. They are in water, food and table salt. One of the worst chloride perpetrators can come from household and industrial cleaners.

So what does all this mean? Don’t despair!

Here are a few steps that can help prevent stainless steel rust.

1. Use the proper tools.

When cleaning stainless steel products,

use non-abrasive tools. Soft cloths and

plastic scouring pads will not harm steel’s

passive layer. Stainless steel pads also can be used but the scrubbing motion must

be in the direction of the manufacturers’

polishing marks.

2. Clean with the polish lines.

Some stainless steel comes with visible

polishing lines or grain. When visible lines are present, always scrub in a motion parallel to the lines. When the grain cannot be seen, play it safe and use a soft cloth or plastic scouring pad.

3. Use alkaline, alkaline chlorinated or nonchloride containing cleaners.

2. Deposits and water.

3. Chlorides.

Mechanical abrasion means those things that will scratch a steel surface. Steel pads, wire brushes and scrapers are prime examples.

While many traditional cleaners are loaded

with chlorides, the industry is providing an ever-increasing choice of non-chloride cleaners. If you are not sure of chloride content in the cleaner used, contact your cleaning supplier. If your present cleaner contains chlorides, ask your supplier if they have an alternative. Avoid cleaners containing quaternary salts; it also can attack stainless steel and cause pitting and rusting.

— 15 —

HC24EO SERIES STEAMER

4. Treat your water.

Though this is not always practical,

softening hard water can do much to reduce

deposits. There are certain lters that can be

installed to remove distasteful and corrosive elements. To insure proper water treatment, call a treatment specialist.

5. Keep your food equipment clean.

Use alkaline, alkaline chlorinated or non-

chloride cleaners at recommended strength. Clean frequently to avoid build-up of hard stubborn stains. If you boil water in stainless steel equipment, remember the single most likely cause of damage is chlorides in the water. Heating cleaners that contain chlorides have a similar effect.

6. Rinse, rinse, rinse.

If chlorinated cleaners are used, rinse

and wipe equipment and supplies dry immediately. The sooner you wipe off standing water, especially when it contains cleaning agents, the better. After wiping equipment down, allow it to air dry; oxygen

helps maintain the stainless steel’s passivity lm.

7. Never use hydrochloric acid (muriatic acid) on stainless steel.

8. Regularly restore/passivate stainless steel.

Review

1. Stainless steels rust when passivity (lm-shield) breaks down as a result of scrapes, scratches,

deposits and chlorides.

2 Stainless steel rust starts with pits and cracks.

3. Use the proper tools. Do not use steel pads, wire brushes or scrapers to clean stainless steel.

4. Use non-chlorinated cleaners at recommended concentrations. Use only chloride-free cleaners.

5. Soften your water. Use lters and softeners whenever possible.

6. Wipe off cleaning agent(s) and standing water as soon as possible. Prolonged contact causes eventual problems.

To learn more about chloride-stress corrosion and how to prevent it, contact the equipment manufacturer or cleaning material supplier.

COOKING HINTS

The steamer efficiently cooks vegetables and other foods for immediate serving. Steam cooking should be carefully time controlled. Keep hot food holding-time to a minimum to produce the most appetizing results. Prepare small batches. Cook only enough to start serving, then cook additional amounts to meet demand.

ACCEPTABLE PAN SIZES

The steamer accommodates combinations of full, half and one-third size pans, solid or perforated.

Model Number of Pans Accommodated

Depth of Pan

1" 21/2" 4" 6"

C24EO3 6 3 2 1

PREPARATION

Prepare vegetables, fruits, meats, seafood and poultry normally by cleaning, separating, cutting, removing stems, etc. Cook root vegetables in a perforated pan. Other vegetables may be cooked in a perforated pan unless juices are being saved. Liquids can be collected in a solid 12" x 20" pan placed under a perforated pan.

Perforated pans are used for frankfurters, wieners and similar items when juices do not need to be preserved. Solid pans are good for cooking puddings, rice, and hot breakfast cereals. Vegetables and fruits are cooked in solid pans in their own juice. Meats and poultry are cooked in solid pans to preserve their juice or retain broth.

Canned foods can be heated in their opened cans (cans placed in 12" x 20" solid pans) or the contents may be poured into solid pans. DO NOT place unopened cans in the steamer.

C24EO5 10 5 3 2

COOKING GUIDELINES

The steamer cooks vegetables, frankfurters, eggs in their shells, and certain other meats or food items at atmospheric pressure.

These cooking guidelines are suggestions only. You should experiment with your food products to determine the cooking times that will give you the best results. Variables which affect cooking time include size, weight, thickness of foods, temperature, density, previous condition of the foods (fresh, pre-blanched or frozen) and degree of doneness desired.

Frozen Food Items

Separate frozen foods into smaller pieces to

allow more efcient cooking.

Use a pan cover for precooked frozen dishes that cannot be cooked in the covered containers in which they are packed if they require more than 15 minutes of cooking time. When a cover is used, approximately one-third additional cooking time is necessary.

Cooking time for frozen foods depends on the amount of defrosting required. If time permits, allow frozen foods to partially thaw overnight in a refrigerator. This will reduce their cooking time.
