In terms of heating methods, the three types differ in their warming techniques and the thickness of materials used.

1. Steam jacketed kettle: This type uses steam generated by a boiler, which is channeled into the kettle for heating. Customers who opt for this heating method typically already have a boiler (Food processing machinery manufacturer Tel: 138*5448-1138).

2. Electric heating jacketed kettle: This type heats by using electric heating tubes to warm thermal oil. Simply put, it operates by electricity, making it very convenient to use anywhere there is a power source.

3. Gas heating jacketed kettle: This equipment mainly consists of a pot body, base, and gas stove, with optional additions such as stirring devices, insulation layers, tilting frames, or support legs. The operation method involves first opening the gas valve, then igniting the gas, manually adding cooking oil, and when the oil temperature reaches the cooking level, adding an appropriate amount of materials. Manual stirring and turning ensure even heating. After processing, the gas is turned off, and the flame is extinguished. By rotating the handle, the pot body tilts via worm gear transmission, allowing the materials to be poured into another container (Food processing machinery manufacturer Tel: 138*5448-1138).

Nowadays, jacketed kettles are increasingly used, gradually replacing traditional wood-fired iron pots. The heating methods for jacketed kettles generally include steam heating, electric heating, and liquefied petroleum gas or natural gas heating, which are energy-efficient, environmentally friendly, and convenient. With technological improvements and rising living standards, food safety and quality requirements have become stricter, leading to the current use of stainless steel in manufacturing jacketed kettles.
Stainless steel jacketed kettles are categorized into steam jacketed kettles, electric heating jacketed kettles, and gas heating jacketed kettles. The differences among them are: electric heating jacketed kettles warm thermal oil via electric heating tubes; steam jacketed kettles use steam from a boiler channeled into the kettle's jacket for heating. Gas heating utilizes natural gas, liquefied petroleum gas, or pipeline gas as the heat source, addressing the need for jacketed kettle use in the absence of steam. If required, temperature control systems or stirring devices can be configured (Food processing machinery manufacturer Tel: 138*5448-1138).
Let’s further examine the working principles of gas jacketed kettles, steam jacketed kettles, and electric heating jacketed kettles.
