Raghav Mixing steam jacket kettle

A steam-jacketed mixing kettle (also called a cooking kettle with agitator) combines the uniform indirect heating of a jacketed steam vessel with a motorized agitator to heat, mix, blend, and continuously scrape high-viscosity or burn-sensitive products during processing.

Agitator & Scraper Assembly: Driven by a top-mounted gear motor, the agitator continuously moves the product. Many units feature Teflon (PTFE) scraper blades that wipe the inner wall to prevent product buildup and scorching.

Agitation Types:

Anchor / Paddle Agitators: Ideal for medium-viscosity liquids, sauces, and stews.

Planetary / Off-Center Mixers: Provides comprehensive coverage across the entire bowl, suitable for thick pastes and sticky confections.

Double-Motion (Counter-Rotating): Uses inner and outer blades rotating in opposite directions for dense materials like peanut butter or cheese sauces.

Hemispherical Inner Vessel: Built with SS304 or SS316 stainless steel to facilitate smooth scraping, efficient heat distribution, and sanitary cleaning.

Pressurized Steam Jacket: Surrounds the lower section of the bowl where steam condenses, releasing latent heat uniformly across the surface.

Tilting & Discharge System: Features a worm-gear handwheel or hydraulic system to tilt the bowl up to 90 degrees for quick product discharge and easy cleaning.

Indirect Steam Heating: High-pressure steam enters the sealed jacketed space, transferring thermal energy through the stainless steel wall directly into the food or chemical batch.

Continuous Mechanical Scraping: As heat transfers into the batch, the motor-driven scrapers continuously lift product off the heated wall and fold it back into the center.

Homogeneous Heat Transfer: The combined action prevents thermal stratification (hot and cold spots), maintains uniform temperature throughout the batch, and drastically reduces cooking cycles.
