Jacketed kettle: Uses steam pressure, and the working pressure should not exceed the rated pressure for extended periods. When adding steam, slowly open the suction valve until the required pressure is reached. The shut-off valve at the condensate outlet should always remain open when equipped with a return bend. If there is no return bend, first open the valve until steam escapes, then reduce the valve opening, maintaining it slightly open until a small amount of steam escapes. The safety valve should be adjusted according to the steam pressure used by each user. During cooking, frequently monitor changes in steam pressure and make timely adjustments using the suction valve. After stopping the steam supply, open the straight plug at the bottom of the kettle to drain residual water. (Food processing machinery manufacturer Tel: 138*5448-1138)

Stainless steel jacketed kettles are categorized into steam jacketed kettles, electric heating jacketed kettles, and gas heating jacketed kettles. The differences between the three are as follows: Electric heating jacketed kettles use electric heating tubes to heat thermal conductive oil; steam jacketed kettles utilize steam generated by a boiler, which is directed into the jacket of the kettle for heating. Gas heating uses natural gas, liquefied gas, or pipeline gas as the heat source, addressing the issue of using jacketed kettles in the absence of steam. If needed, temperature control systems or stirring devices can also be configured (Food processing machinery manufacturer Tel: 138*5448-1138).

Now, let’s take a look at the working principles of gas jacketed kettles, steam jacketed kettles, and electric heating jacketed kettles.

The working principle of a gas jacketed kettle is as follows: First, open the gas valve of the jacketed kettle and ignite the gas. Manually add cooking oil to the kettle. When the oil temperature reaches the cooking temperature, add an appropriate amount of ingredients and manually stir or flip the kettle to ensure even heating (similar to the principle of a household frying pan). After processing the ingredients, turn off the gas and extinguish the flame. Rotate the handle to tilt the kettle body using the worm gear and worm drive mechanism, pouring the ingredients into another container. This completes the processing of the ingredients.
