Introduction
In the food processing, pharmaceutical, and cosmetic industries, high-viscosity materials such as sauces, fillings, jams, and pastes demand uniform heating, thorough mixing, and zero dead-angle stirring to ensure product quality and production efficiency. The planetary jacketed kettle (also known as a planetary stirring cooker) is a high-performance processing equipment designed specifically for these requirements. It integrates advanced planetary stirring technology, a high-strength stainless steel structure, and multi-heating options, becoming the core equipment for modern industrial production.
1. Core Technology Advantages
1.1 Planetary Stirring System (No Dead-Angle Mixing)
The core innovation lies in its planetary motion principle: the stirring unit rotates on its own axis (rotation) while revolving around the pot’s central axis (revolution). With a non-integer transmission ratio, the stirrer covers every inch of the pot’s interior, eliminating stirring blind spots completely.
- 360° Full Contact: Food-grade scrapers on the stirring arms closely adhere to the pot wall and bottom, continuously scraping off materials to prevent scorching and ensure uniform heating.
- Variable Speed Control: Equipped with a frequency conversion speed regulator, the stirring speed can be adjusted steplessly (0-30 rpm) to adapt to different material viscosities and process requirements.
1.2 High-Efficiency Jacketed Heating Technology
The double-layer jacketed design forms a closed heating cavity, supporting four mainstream heating methods to match diverse factory conditions:
- Steam Heating: Fast, uniform, and precise temperature control (≤120°C), ideal for large-scale continuous production.
- Gas Heating (LPG/Natural Gas): Rapid temperature rise, low cost, suitable for factories without steam systems.
- Electric Heating (Thermal Oil): Clean, easy to operate, accurate temperature control (±1°C), perfect for small and medium-sized enterprises.
- Electromagnetic Heating: Energy-saving (30-50% less energy than gas), fast heating/cooling, no thermal inertia, and long service life.Heating Performance Highlights:
- Large heating area, high thermal efficiency (≥90%), and fast material heating.
- Uniform heat distribution avoids local overheating, preserving the original flavor, color, and nutrients of materials.
1.3 Advanced Sealing & Transmission Technology
- Food-Grade Sealing: The stirring shaft uses a mechanical seal + silicone gasket combination, which is high-temperature resistant, corrosion-resistant, and prevents leakage, ensuring food hygiene and safety.
- Stable Transmission: The gearbox adopts a hard-tooth surface design, with low noise (≤60dB), high torque, and stable operation, reducing maintenance costs.
2. Structural Performance & Design
2.1 Food-Grade Stainless Steel Construction
- Pot Body: Made of SUS304/SUS316L stainless steel, one-piece stamped hemispherical design (5mm thick), with high roundness accuracy and a smooth inner surface (Ra ≤0.8μm) to avoid material adhesion and facilitate cleaning.
- Frame & Support: Heavy-duty stainless steel frame, welded as a whole, with strong stability and load-bearing capacity, suitable for long-term high-intensity work.
2.2 Hydraulic Lifting & Tilting System (Optional)
- Hydraulic Stirring Lift: With one-button control, the stirring arm can be lifted automatically, no need to disassemble the stirrer, convenient for cleaning and maintenance.
- Hydraulic Pot Tilting: The pot body can be tilted 90° via hydraulic pressure, enabling complete discharge of materials without residue, saving labor and improving production efficiency.
2.3 Intelligent Control System
- PLC Microcomputer Control: Equipped with a touch screen, integrating temperature control, speed adjustment, timing, and fault alarm functions.
- Visual Operation: Real-time display of temperature, stirring speed, and working status, with one-button start/stop, simple operation, and reduced labor requirements.
- Safety Protection: Over-temperature, over-pressure, and overload protection devices ensure safe and stable operation of the equipment.
