Stainless Steel Reactor

Stainless Steel Reactors | High-Temperature, High-Pressure Agitation and Synthesis Reaction Equipment for the Chemical and Pharmaceutical Industries

💡Stainless steel reactors made of 304/316L grade, suitable for high-temperature, high-pressure, and vacuum applications under various operating conditions. Available with a variety of stirrer types and an integrated temperature-controlled condensation and drop-feeding system, these reactors are used for synthetic reactions in the pharmaceutical, chemical, new materials, and food industries.

I. Product Introduction

Stainless steel reactors are vessels used to carry out physical or chemical reactions, capable of withstanding high temperatures, high pressures, and vacuum conditions. Depending on process requirements, they can be equipped with stirrers, heating/cooling systems, drop-feeding devices, and condensation/reflux systems, and are widely used in the chemical, pharmaceutical, dye, food, and new materials industries.

II. How It Works

The materials are added to the reactor according to the specified ratio, and the stirrer facilitates mixing and mass transfer. Steam, heat transfer oil, or cooling water is circulated through the jacket or internal coils to control the reaction temperature. A vacuum can be applied, or an inert gas can be introduced. Catalysts or solvents can be added dropwise during the reaction, and the gases generated are either recycled via a condenser or vented. After the reaction is complete, the material is discharged through the bottom discharge valve.

III. Main Structural Components

✅ Reactor Vessel (Jacketed/Half-Pipe/Coiled Tube)

A multi-form heat exchange structure that enables rapid heating and cooling, making it suitable for both high- and low-temperature reaction conditions.

✅ Agitation devices (paddle-type, turbine-type, anchor-type, frame-type, twin-screw-type)

A variety of impeller types are available to accommodate materials of different viscosities, enhancing mixing, mass transfer, and emulsification.

✅ Drive Unit (Motor + Gearbox + Frame)

Smooth power transmission, ample torque, low operating noise, and suitable for long periods of continuous operation.

✅ Mechanical seal or magnetic seal

Optional double-ended mechanical seals or fully enclosed magnetic seals are available to prevent any medium leakage.

✅ Heating/Cooling System

Connect steam, heat transfer oil, and refrigerant to precisely control the reaction temperature inside the reactor.

✅ Droplet-feeding tank, condenser, receiving tank (optional)

Enable the uniform, continuous addition of additives and the condensation, recovery, and recycling of solvents.

✅ Sensors for temperature, pressure, pH, etc.

Collect process data online in real time and monitor the reaction status in real time.

✅ PLC Control System

Programmable control parameters; compatible with DCS for centralized remote monitoring and control.

IV. Core Advantages

✅ Wide range of operating conditions: Withstands high pressure (10 MPa), high temperature (300 °C), and vacuum (-0.1 MPa).

With a wide range of pressure and temperature resistance, it can accommodate both positive and negative pressures to meet the requirements of various synthesis processes.

✅ High heat transfer efficiency: Available in various configurations—such as jacketed, half-tube, and coil—providing a large heat transfer surface area.

Heat exchange structures are selected as needed, ensuring uniform temperature control without localized overheating.

✅ Wide range of mixing types: Select a model based on material viscosity (1–10⁶ cP).

A suitable mixing configuration is available for materials ranging from low viscosity to ultra-high viscosity.

✅ Reliable Sealing: Optional double-face mechanical seals or magnetic seals ensure leak-free operation.

Magnetically sealed structures should be used as a priority for flammable, explosive, and volatile materials.

✅ High level of automation: Can be integrated with a DCS system to enable automatic recipe control.

One-touch start/stop, automatic feeding, and temperature control reduce human error.

V. Typical Use Cases

✅ Pharmaceutical Manufacturing: Synthesis of active pharmaceutical ingredients (APIs), esterification, hydrolysis, and condensation reactions.

Full-process synthesis lines for pharmaceutical intermediates and active pharmaceutical ingredients (APIs).

✅ Fine Chemicals: Production of resins, adhesives, coatings, and dyes.

Polymerization of polymers; synthesis and processing of additives.

✅ New Materials: Silicones, polyurethanes, and precursors for lithium-ion battery cathode materials.

Synthesis and preparation of lithium battery materials for new energy applications and new organic materials.

✅ Food: Emulsification, seasoning reactions, enzymatic hydrolysis.

Enzymatic hydrolysis and emulsification/homogenization of food ingredients.

✅ Petrochemicals: Production of additives and catalysts.

Synthesis reactions for oil additives and various chemical catalysts.

VI. Optional Configurations

✅ Explosion-proof motor + explosion-proof control unit

Complete explosion-proof systems for flammable and explosive workshops, compliant with explosion-proof standards.

✅ Torque sensor (monitors material viscosity)

Monitor viscosity changes in real time to determine the end point of the reaction.

✅ Automatic Feed and Discharge Valves

Pneumatic/electric valves for sealed, automated feeding and discharging.

✅ Nitrogen or steam purge system

Replace the air inside the reactor to protect sensitive materials from oxidation.

✅ Sight glass with scraper (to prevent condensation from obscuring the view)

Automatically wipes away condensation from the sight glass, ensuring a clear view of the reactor’s operating conditions at all times.
