Professional Introduction of Industrial Jacketed Kettle

Professional Introduction of Industrial Jacketed Kettle

The industrial jacketed kettle is a core pressure heating and processing vessel widely applied in food processing, pharmaceutical manufacturing, fine chemical and light industrial industries. Featuring a dual-wall jacketed structure and modular functional design, this equipment realizes homogeneous heat transfer, precise temperature control and standardized material processing, complying with GMP, food safety and industrial production specifications. It is applicable for continuous batch processing of liquid, paste and semi-solid materials, covering heating, boiling, simmering, concentration, melting, sterilization and thermal preservation procedures.

1. Product Structural Composition

The jacketed kettle adopts an integrated dual-layer welded structure, mainly composed of an inner tank, outer jacket, support frame, transmission system, auxiliary functional components and safety protection devices, with all material contact parts made of high-grade SUS304/SUS316L stainless steel to achieve corrosion resistance and sanitary grade requirements.

1.1 Inner Tank Assembly

The inner tank is the material processing cavity with a mirror-polished inner surface and arc transition structure, which eliminates sanitary dead corners and avoids material adhesion and scorching. The tank body adopts integral stamping and seamless welding technology, with high structural rigidity and pressure resistance, adapting to high-temperature and high-pressure continuous working conditions. According to process demands, the inner tank can be equipped with customized stirring paddles including anchor-type, frame-type and paddle-type structures to solve material stratification and uneven heating problems of high-viscosity materials.

1.2 Outer Jacket Layer

The interlayer cavity between the inner tank and outer shell is the core heat transfer unit. Heating media such as saturated steam, thermal oil and hot water circulate in the closed jacket cavity to realize indirect heat transfer. The jacket layer is equipped with medium inlet and outlet ports, pressure gauges, vent valves and drainage interfaces to monitor and adjust heat transfer parameters in real time. The outer jacket surface is fitted with thermal insulation cotton and protective shell to reduce heat loss and prevent scalding risks.

1.3 Support and Tilting Mechanism

The equipment is equipped with a rigid steel support frame with stable load-bearing performance. The tilting-type jacketed kettle adopts a worm gear and worm transmission structure, supporting 180° manual or electric tilting discharge, which improves material discharging efficiency and reduces residual volume. The fixed-type kettle adopts an integrated fixed support, matching bottom discharge valves for quantitative discharge and pipeline continuous production.

1.4 Drive and Control System

The stirring drive system consists of a speed-reducing motor and frequency converter, realizing stepless speed regulation to adapt to different material viscosity and processing technologies. The electrical control cabinet integrates temperature sensors, pressure transmitters and programmable controllers to achieve automatic temperature constant, over-temperature alarm and timing operation functions.

1.5 Safety Protection Device

Equipped with pressure relief valve, over-pressure automatic shutdown device, water shortage protection and locking safety mechanism, it effectively avoids pressure vessel overload operation and eliminates potential safety hazards such as explosion and scalding, fully meeting industrial pressure vessel safety operation standards.

2. Core Functional Characteristics

2.1 Uniform Indirect Heat Transfer, No Local Overheating

Different from direct heating equipment, the jacketed kettle relies on closed interlayer medium circulation for omnidirectional surround heating. It features large effective heating area, high thermal efficiency and stable heat conduction, completely eliminating hot spots and material scorching. This ensures consistent material processing quality and maximizes the retention of material nutrients and flavor components.

2.2 Diversified Heating Modes and Precise Parameter Control

The equipment supports multiple heating modes including steam heating, electric thermal oil heating, electric water heating and gas heating, adapting to different factory energy supply conditions and process temperature requirements. The intelligent temperature control system achieves accurate temperature adjustment within the range of 0-200℃, with constant temperature error controlled within ±1℃, realizing standardized and repeatable production.

2.3 Sanitary and Easy Maintenance, Meeting GMP Standards

The closed jacket heat transfer structure reduces heat radiation and loss, with high heat utilization rate. The frequency conversion stirring and intelligent constant temperature system effectively reduces energy consumption. The simplified mechanical structure reduces failure rate and daily maintenance cost, realizing long-term stable continuous operation.
