Vulcan K Series Kettles

The steam-jacketed kettle is ideal for soups and stocks because it has low temperature, easy control, heavy-bar rim, 316 liner, embossed gallon markings, and true working capacity.

Steam-jacketed kettles are ideal for in your restaurants, college and universities, K-12 school food service, correctional facilities, military, and business and industry. For those long cooking operations such as soups, stews, and sauces. Factory based soup stocks and bases do not come close to the flavor that's in a homemade soup stock.

The perfect soup stock starts with fresh vegetables and your meat products. We're going to make a beef stock today. So the first thing we're going to do is take the beef bones, place the bones in the center of the oven, set your timer for 1 hour. To give that deep, rich color that you look for in a stock, you want to paint the bones with the tomato sauce or tomato paste.

Take a little mirepoix and pour it on top. This allows these vegetables to sweat and they become full flavorful when they go into the stock. Back into the oven for 15 minutes. And now I trim my vegetables. Save the trimmings because this is what's going to make your stock. Okay, to make your Sachet d' Epices, you would take a cheese cloth, you would take a few pepper corns, a couple of fresh bay leaves, some fresh thyme, garlic, and parsley. You would take this nice little package and wrap it up. Take your butcher string, put this into your stock just before you start to cook it. Okay, the trimmings, go into the pot. We take our baked bones and put them in the pot. The key to the perfect soup stock is starting with cold water. You come on, turn the kettle on, add your previously made sachet into your stock. Make sure your temperature is in the simmer because you don't want to boil your stock.

We have a stock that's been cooking all night long and now it's ready to be strained. Get out your bag and you might want to strain off any of the other impurities that float to the surface.

Now I'm installing the pouring-lip strainer. This is going to allow me to easily strain the kettle into the storage container. Look at that deep, rich color. The next step in the perfect stock is the second straining. You would take a fine mesh strainer and there you have it. Ready for the refrigerator and in the morning the fat will rise to the surface and congeal and can be easily scraped off.

It's very easy to clean. Remove this attached strainer, tilt the kettle, and with the optional hose assembly, spray it out in the tilted position, add a little water. Turn the kettle on to get some heat, add some detergent, bring the water up to temperature and scrub it out.

Customer questions about this product

My business is at a high elevation; does this change anything when I order gas cooking equipment?
Many gas equipment manufacturers need to make adjustments to the equipment so it operates correctly at elevations over 2,000 feet. Sometimes we can special order from the manufacturer and have your cooking equipment delivered ready-to-go, but in cases where your unit is in stock and waiting to ship, you’ll need to have a qualified service technician come to your location and alter your unit at the time of installation so that it is compatible with a higher elevation. Contact our Special Orders team prior to placing your order, and we will let you know what will work best for the equipment you are planning to purchase.

Vulcan K40GL-NAT Details

Increase your production capabilities while saving energy and labor with this Vulcan K40GL-NAT 40 gallon stationary natural gas kettle! Boasting 100,000 BTU of heating power and a 40 gallon capacity, this kettle allows you to prepare large batches of your signature soups, stews, or pasta. Vulcan's exclusive kettle design has up to 50% more working capacity than competitive brands, making it the perfect choice for busy industrial kitchens.

Thanks to the 2/3 jacketed design, this kettle has a larger heat transfer surface area for more thorough cooking. This means you'll have faster heat-up and cook times, and no hot spots or scorched products, which increases production and efficiency. Plus, faster cook times mean less energy used, so your utility bills will be lower. With more even heating, there is less need for frequent stirring or "pot watching." A spring assist hinged cover minimizes evaporation to help retain heat, and a drop down lift handle makes it easy to open and close the lid to access the kettle's contents.

This unit features user-friendly controls that allow you to warm, simmer, or boil your products. A low water cut-off and pressure limit switch make it as safe to use as it is efficient. The 304 type stainless steel construction is highly stain and corrosion resistant, which makes cleanup much easier. And, to further expedite the cleaning process, the kettle's ellipsoidal bottom directs products to a 2" draw off valve with a strainer. Flanged feet ensure superb stability. Natural gas and a 120V electrical connection is required.
