GENERAL

INTRODUCTION

Vulcan-Hart Ovens are produced with quality workmanship and material. Proper installation, usage, and maintenance of your oven will result in many years of satisfactory performance.

The Vulcan Cook & Hold Oven is more than just an oven – it’s a “System”; precisely controlled heat, regulated to retain ascorbic acid and maximize the nutritional value, taste and eye-appeal of food. In this environment, virtually any food product can be prepared to delicious perfection in just ONE oven! “System” food preparation eliminates the need for multiple ovens with duplicate features.

This manual is provided to assist persons responsible for the operation

and maintenance of the oven with a simple, but comprehensive understanding of its proper use. We recommend that you thoroughly read this entire manual and carefully follow all of the instructions provided prior to placing the oven into operation.

As with any piece of food service equipment, this oven system requires a minimum of care and maintenance. Recommended procedures are contained in this manual and should become a regular part of the operation of the unit.

Vulcan Cook & Hold Oven is the right choice for low temperature food preparation.

PRINCIPLES OF

COOK & HOLD OVENS

Vulcan Cook & Hold Ovens are designed and perfected for cooking at a lower temperature. The principles of Low Temperature Cooking and Holding can be summarized into several objectives: increased product yields,

increased profits from increased yields, increased moisture retention, increased tenderization, and consistency of doneness.

When the Vulcan Cook & Hold Oven finishes the cooking cycle, it automatically switches to the hold cycle. Throughout this manual we recommend holding temperatures such as 140⁰F

(60⁰C). This temperature refers to the oven’s hold temperature setting and not to the internal temperature of the food being roasted. The internal product temperature will run below the hold temperature. (For example: roast beef held at 140⁰F will be about 130⁰F internally or medium rare.)

All meat products contain enzymes. These enzymes perform the important function of tenderizing the meat when they reach temperatures of 100⁰F (38⁰C) to 140⁰F (60⁰C). As

these enzymes are heated, they break

VCH & VRT SERIES OVENS F-41162 (02-16)

down the connective tissue that is inherent in all red meat products.

The hold cycle allows this natural tenderization process to proceed in an orderly manner. As long as the internal temperature of the meat does not exceed 140⁰F, the process will continue. Once the temperature reaches 140⁰F the process will stop, because the enzymes will be deactivated.

This tenderization process makes the meat more flavorful. It is similar to aging

BENEFITS OF

COOK & HOLD OVENS

Superior Results: Low temperature

roasting has been recognized as the best method for preparing meat and poultry because of increased tenderness, more even roasting, and a juicer product.

Increased Sales: You will attract more customers and have more repeat business because you are now producing a superior product in your market area. All of your products will be unique, from prime rib and chicken to BBQ ribs, pork roasts, and even bakery items!

Reduced Energy Costs: It costs significantly less to run a Vulcan Cook & hold Oven instead of a conventional oven. Also, in most areas, no exhaust hood is needed.

meat before it is sold. The longer the hold, the higher degree of tenderization.

Each hour of holding is equal to one day of aging.

VRT MODEL: The Vulcan VRT Model is also a “Rethermalization Oven System.” The VRT Model is specifically designed to retherm chilled/thawed food product as well as prepared frozen food products either in bulk or individually wrapped and sealed packages.

Reduced Shrinkage of Product: You can cut your percent of shrinkage from 25 to 30% down to 5 to 10%. This means more servings to sell to your customers! The Vulcan Cook & Hold

Oven can pay for itself in just months, depending on your volume.

Reduced Labor Cost: Your cooks do not have to come in early to put roasts in or stay late to take them out of the oven. Holding banquet foods in a Vulcan Cook & Hold Oven reduces that last minute party prep to almost nothing.

VCH & VRT SERIES OVENS F-41162 (02-16)

COMPARISON OF

COOK & HOLD OVENS

“The Comparison Stops Here” – more than a catchy slogan, it’s a fact.

Convection ovens, unlike Vulcan Cook & Hold Ovens, blast high temperature dry air over the product. The end result with convection oven cooking is excessive and unnecessary shrinkage.

Vulcan Cook & Hold Oven Systems:

1. Offer a lifetime heating element warranty.

2. Provide a natural roasted brown, caramelized product

without coloring agents. “You can taste the difference.”

3. Can bake anything from meat, poultry, fish, cakes, cookies, puff pastries, and even popovers.

4. Are accurate, plus or minus 5⁰F.

5. Are easy to clean.

6. Have inside and out.

MAINTENANCE

CLEANING

The Oven and its parts are hot. Be very careful when operating, cleaning, or servicing the oven.

Always unplug electrical power supply before cleaning.

Avoid splashing water into upper areas of the oven to prevent damage to electrical components or connections.

Never spray the unit with a hose. Never use harsh chemicals or abrasive pads to clean the oven.

HEAT TINT: Darkened areas, called “heat tint,” may appear on stainless steel exposed to excessive heat. Excessive heat causes the protective film to thicken. This is unsightly, but is not a sign of permanent damage.

DAILY:

1. Unplug electrical power supply.

2. Allow oven to go through cool down period before cleaning.

3. Remove the Interior Side Racks

4. Take the Interior Side Racks to a sink or dishwasher for a thorough cleaning. Use a mild soap and water solution to clean these items.

5. Clean the interior of the oven with a mild soap and a soft damp cloth. Wipe dry with a soft dry cloth.

6. Reassemble oven.

7. Clean the exterior of the oven

with a clean damp cloth.

DOOR GASKET CARE

DOOR GASKET:

At least once a week, thoroughly check the door gasket for damage/wear. A damaged gasket can cause inefficient and unsatisfactory operation of the oven.

If the gasket requires cleaning:

1. Gently wash gasket using a moist cloth, a mild detergent solution, and warm water.

2. Rinse with a fresh cloth

moistened in warm water to remove all traces of detergent.

3. Gently wipe dry with a clean dry

cloth. Never apply food oils, or petroleum

lubricants directly to the gasket(s). Petroleum based solvents and lubricants will reduce the gasket’s life.

COOKING

INTRODUCTION

This cooking guide has been produced for your Vulcan Cook & Hold Oven System. It should be used as a handy reference when using your oven. The guide has been developed to help answer questions which you may have relating to product preparation as well as making you familiar with the operation of your Cook & Hold Oven.

When using your oven, experiment with your own house specialties. The degree of doneness varies based upon individual preferences. These preferences can be easily accomplished by varying the recommended time guidelines in this manual. The guidelines which are presented in this manual are suggested and have been tested to insure product preparation as indicated.

The concept of “Low Temperature Cooking” is not a science, it is an art. Chefs from around the world vary in terms of the doneness and appearance in the products which they prefer. Therefore, we suggest first understanding what your Oven System will do for the multitude of applications available to you.

COOKING RACK

Depending upon the size of the Cook & Hold Oven, each unit is supplied with a specially designed cooking rack(s). The cooking rack must be used when cooking food products to insure absolute product quality and integrity.

F-41162 (02-16)

The cooking rack is simply placed inside a standard 18” x 26” sheet tray (2/1 Gastronome) and the product which is to be cooked and held is placed on top of the cooking rack. When more than one product is being prepared, the food products should not be cramped together onto one cooking rack. Sufficient room should separate the products on a single cooking rack to insure proper circulation of air around the product.

When loading the oven, an additional 18” x 26” sheet tray, in an inverted position, (Fig. 5) should be placed directly above the food product being prepared. This creates the necessary air flow pattern to produce highly desirable carmelization and uniform roasting of the product.

INVERTED SHEET TRAY

Fig. 5

A helpful hint when loading your food product on the cooking rack is to either line your 18” x 26” sheet tray with foil, or spray with a quality vegetable oil. This helps with easy clean up after use.
