Electric Thermal‑oil Heating

Working Principle

1. Thermal Oil Heating: The interlayer is filled with thermal oil. Electric heating tubes heat the thermal oil, which transfers heat evenly to the hemispherical pot body. Thermal oil has large heat capacity with minor temperature fluctuation. The maximum temperature can reach 230℃ for excellent constant-temperature performance. 
2. Planetary Stirring: The stirring blades perform both rotation and revolution with a non-integer transmission ratio. Fitted with food-grade PTFE scrapers for bottom and wall scraping, they closely fit the inner pot wall in 360° without stirring dead zones. High-viscosity materials are less prone to burning. 
3. Discharging Method: After cooking, manually turn the handwheel. The worm and worm gear mechanism drives the pot body to flip for discharging, facilitating pot cleaning.

Equipment Structure

1. Hemispherical Pot Body: One-piece stamped forming. The inner layer is SUS304 stainless steel, and the outer interlayer holds thermal oil. 
2. Planetary Stirring Assembly: Variable frequency reduction motor, multi-claw stirring blades, PTFE wall scrapers. 
3. Thermal Oil Heating System: SUS304 electric heating tubes, thermal oil medium, temperature sensors, temperature controllers, over-temperature protection. 
4. Hand Tilting Frame: Stainless steel frame with manual worm & worm gear pot tilting mechanism. 
5. Electric Control System: Independent waterproof control cabinet, supporting temperature control, variable frequency speed regulation, overload protection and emergency stop button.

Applicable Materials

Hot pot base, chili sauce, beef sauce, broad bean paste, fruit jam, red bean paste, lotus seed paste, jujube puree, mooncake fillings, and boiling of high-viscosity pre-cooked dish materials.

Advantages

It supports long-time constant-temperature boiling with small temperature fluctuation, ideal for sauces requiring prolonged slow simmering in production processes.

Equipment Features

1. Thermal oil boasts strong heat storage capacity. The pot body is heated uniformly with stable temperature control and small temperature difference, avoiding local burning, and suitable for long-time boiling. 
2. Planetary multi-claw full wall scraping stirring combining revolution and rotation continuously scrapes materials from pot bottom and wall to prevent high-viscosity materials from sticking. 
3. Semi-automatic structure: automatic stirring operation and manual pot tilting by worm & worm gear. Low equipment cost, simple maintenance and convenient cleaning for product changeovers. 
4. Variable frequency stirring speed adjustment, adjustable from 10 to 24 r/min, adapting to materials of different viscosities. 
5. Interlayer heat insulation keeps low surface temperature for safe workshop operation; no open flame. 
6. Material contact parts adopt SUS304 stainless steel, detachable for cleaning and complying with food hygiene requirements. 
7. Optional configurations: pot cover, electric lifting of stirring arm, digital oil temperature display, over-temperature alarm.
