PRO MAKINA · Agitated Reactor
Overview
An agitated reactor is a process vessel in which liquid or liquid-solid components are kept in motion by an agitator to make them homogeneous, while temperature, time and feed sequence are controlled as the process requires. It can be used for blending, dissolution, extraction or chemical reaction steps.
Mixing performance mainly depends on agitator type (propeller, turbine, anchor etc.), impeller diameter and geometry, speed, position in the tank and baffles. These are selected according to product viscosity, density, solids content and the purpose of the process.
If the process requires heating or cooling, a jacket can be added to the shell or a coil inside the tank. Whether the reactor runs under pressure is defined by the process; agitated reactors operating at atmospheric pressure are not pressure reactors.
01Process Flow
The diagram shows the general flow in which raw materials are fed to the reactor, processed under controlled agitation and discharged after process control. Feed sequence, time and temperature follow the product recipe.
Scroll horizontally to view the full diagram.
Raw material feed: Liquids are pumped in and solids added through the cover inlet in recipe order.
Controlled agitation: The agitator keeps the mixture homogeneous at a speed suited to product viscosity.
Process control: Temperature, level and time are monitored; samples are taken if required.
Product discharge: Finished product leaves through the bottom valve to storage, filtration or filling.
Heating or cooling: If required, a heating or cooling medium is supplied to the jacket or coil.
Medium return: The medium returns to the plant utility circuit.
A heating or cooling circuit is added only if the process requires it; it is shown as a dashed line in the diagram.
02Applications
01Extracting humic sources such as leonardite by mixing in an alkaline solution. Solids ratio, time and temperature are set from raw material analysis; the insoluble fraction is separated in a later step.
Fertilizer and Granulation Plants
02Mixing fertilizer raw materials with water and additives into a homogeneous liquid or suspension product. If the only goal is to dissolve a solid, a dissolution tank can be the simpler solution.
Dissolution Tank
03Preparing and keeping homogeneous the coagulant, pH correction or polymer solutions used in treatment plants. Low-speed mixing is preferred for polymer solutions to protect their structure.

04FAQ
It is process equipment in which liquid or liquid-solid components are made homogeneous by an agitator while temperature, time and feed sequence are controlled as the process requires.
Product viscosity, density, solids content and the process purpose are decisive. Propeller or turbine agitators are considered for low viscosity, anchor agitators for high viscosity.
Not every agitated reactor runs under pressure. If the process does not require pressure, an atmospheric design is sufficient; where pressure is needed, a pressure reactor is assessed separately.
If the process requires it, a jacket on the shell or a coil inside the tank can provide heating or cooling. Method and surface area are defined from process data.
Process purpose, raw materials and recipe, working volume, product viscosity and density, temperature requirement and chemical properties.
