What is a steam jacketed kettle?

Steam-jacketed kettles are very large, deep kettles mounted on a pedestal or legs to stand on the floor. They are used in institutional and industrial kitchens. The bottom two-thirds of the kettle are covered by a metal jacket; shallow ones may be fully-jacketed.

How hot can a steam kettle get?

240ºF to 280ºF.
The temperature of the heat is determined by pressure, ranging from 1 to 50 psi. This produces temperatures ranging from 240ºF to 280ºF. In traditional stock pot cooking, the same heat range can be achieved, but it comes from only the bottom of the basin, losing heat as it rises.

What controls the temperature in a jacketed steam kettle?

The temperature of steam inside a pressurized jacket is based on the pressure. With higher pressures a higher temperature can be achieved. Thus, a kettle with a jacket pressure of 1,5 bar produces higher temperatures than one with 1,0 bar jacket pressure.

What is a steam jacket pan?

The steam jacketed kettle or evaporating pan is an evaporator that can be used for the bulk evaporation of water from aqueous liquids. It is constructed in the form of a hemispherical shaped shell usually made of stainless steel that is comprised of an inner pan or ‘kettle’ and an outer pan or ‘jacket’.

What are the advantages to using a steam jacketed kettle?

Greater productivity – Steam jacketed kettles offer faster cooking times because two thirds of the cooking surface comes into contact with the product at a much lower temperature, compared to stock pots that use a much higher temperature only at the bottom of the pot.

What can you cook in a steam jacket kettle?

Chefs that frequently cook foods like sauces, pastas, puddings, stews, jams, jellies, soups, rice, eggs, (and even delicate foods like chocolates) – can get a lot of bang for their buck with a steam jacketed kettle.

What is double jacketed kettle?

Our Double Jacketed Steam Kettle is the best solution in the production of products such as sauces, jams, marmalade and seasonings. This Steam Kettle concentrates, cooks, and de-aerates the product at low temperatures.

What can I cook in a steam kettle?

Can you cook meat in a steam kettle?

At high steam pressures, you can actually brown meat in a steam kettle. Kettle sizes range from one quart up to 200 gallons for very large institutions. The most popular sizes for the restaurant operator are between 20 quarts and 40 gallons.

How does a commercial steam kettle work?

Steam-jacketed kettles utilize steam energy to transfer heat via conduction to the food product inside. The energy source — electric, gas and direct steam — that operates the unit helps define the categories of kettles available to operators.

How does a direct steam kettle work?

Direct steam kettles get their steam from an external boiler that pumps steam into the kettle jacket to heat the food. Self-contained steam kettles come from the factory filled with distilled water that is then heated to steam, which cooks the food.

What can I cook with a steam jacketed kettle?

This kind of kettle can cook large amounts of stew, pasta, or chili and can also be used to braise meat, cook dessert, or reheat various foods. Steam-jacketed kettles tend to be popular for institutional use because they require less stirring, can simmer longer-cooking recipes, and are less apt to burn food.

What is a steam-jacket Kettle?

Steam-jacketed kettles can produce greater volumes with increased consistency, while reducing labor for both preparation and cleaning. Here is a quick overview of this type of foodservice equipment.

What size steam kettle do I need for my food service operation?

Direct steam kettles offer greater efficiency, cooking the fastest with the highest capacity as compared with electric and gas models. Kettle sizes range from 5 to 200 gallons, although 40 gallons represent the most common size commercial foodservice operators tend to use.

Why are kettles jacketed?

The majority of kettles are two-thirds jacketed, which means that the unit transfers heat energy not only from the bottom of the kettle, like in a stock pot on a range, but also from the sides. This dramatically increases the surface area for energy absorption into the product.

What is the operating pressure of a stainless steel kettle?

The operating pressures of these kettles range from 45 PSI to 50 PSI, which produces an even temperature from the entire jacketed surface of 267 degrees to 338 degrees F. These units feature either 304 or 316 stainless steel construction.
