Gas Heating

Working Principle

Natural gas or liquefied petroleum gas (LPG) is used as the heat source. The burner directly heats the bottom of the jacketed pot, and indirect heat exchange is realized through the jacket. An anchor-type wall-scraping stirring mechanism fitted with food-grade PTFE scrapers is installed inside the pot. The stirring blades rotate closely against the pot bottom and wall to continuously turn materials and prevent high-viscosity materials from burning or sticking to the pot. The gas fire power is adjustable. After boiling, the pot can be fully tilted from 0° to 90° for direct material discharge driven by manual worm & worm gear. No external boiler is required; the equipment only needs a gas supply and power supply for operation.

Comparison: The electric thermal oil model heats via thermal oil heated by electric tubes. The electromagnetic model adopts electromagnetic induction heating. The gas model uses direct combustion heating with low fuel operating cost, suitable for workshops with gas pipelines.

Equipment Structure

1. Hemispherical Double-layer Pot Body: Material contact parts are made of food-grade SUS304 stainless steel with jacket heat exchange structure and outer polyurethane thermal insulation layer. 
2. Stirring Assembly: Anchor-type wall-scraping stirring blade with variable frequency speed regulation and food-grade PTFE scrapers. Blades are detachable for cleaning. 
3. Gas Combustion Heating System: Industrial gas burner, gas solenoid valve, flame failure protection device and gas pipeline. 
4. Tilting Mechanism: Small-capacity models adopt manual worm & worm gear tilting; large-capacity versions can be equipped with hydraulic cylinders for labor-saving discharging. 
5. Stainless steel frame base with stable load-bearing performance.

Applicable Materials

Boiling of chili sauce, mushroom sauce, meat paste, fillings, ointments, fruit jam, brine and pre-cooked dish soup. Also applicable to meat pre-boiling and vegetable blanching. Suitable for condiment factories, cooked food factories, pre-cooked food workshops and central kitchens. It is the preferred option for workshops with natural gas or LPG supply.

Equipment Features

1. Direct gas heating delivers low operating cost and fast temperature rise. The fire power can be adjusted automatically for stable temperature control, with a maximum temperature up to 300℃. 
2. 360° wall-scraping stirring keeps materials continuously turned. High-viscosity sauces are less prone to bottom coking, achieving uniform color of finished products. 
3. The pot can be fully tilted from 0° to 90° for thorough discharging. Stirring blades are detachable and the pot is easy to rinse, complying with SC food production hygiene requirements. 
4. Complete safety protections: automatic gas cut-off upon flameout, gas leakage detection (optional), over-temperature protection, motor overload protection and emergency stop button to avoid gas safety hazards. 
5. No steam boiler or large-capacity power transformer required. Ideal for plants with limited power capacity and available gas supply.
