What is a stirred process tank and when is it needed?
A stirred process tank is a tank equipped with some form of stirring system used to mix, homogenize or circulate liquids and process materials in industrial processes.
This type of tank is often used when the contents need to be kept in motion to reduce the risk of stratification, sedimentation or uneven temperature distribution depending on the process and application.
Processöverskott offers both new and used stainless steel tanks in stainless steel 304 and acid-resistant 316 in various designs where stirring solutions may occur depending on the specification and application.
Function and structure
Stirred process tanks are used in processes where liquids or ingredients need to be mixed, homogenized or kept in motion during operation.
Tanks may be available in both vertical and horizontal designs depending on the installation conditions and application.
The agitation system usually consists of a motor and some type of agitator or impeller placed inside the tank depending on the process requirements and the characteristics of the liquid.
The tanks can also be equipped with, for example, level measurement, temperature-related solutions, CIP systems and inspection hatches depending on the specification and process requirements.
Materials and construction
Stirred process tanks are often manufactured in stainless steel 304 or acid-proof 316 depending on the properties of the liquid and the requirements of the process.
Stainless steel is used in many industrial applications where cleanability and resistance to corrosion are relevant factors.
Tanks are usually welded and may have different surface treatments such as grinding or polishing depending on the application and requirements of the process.
Construction features such as wall thickness, reinforcements and agitator design vary depending on the tank size, pressure design and specification.
Pressurized and atmospheric solutions
Stirred process tanks can come in both atmospheric and pressurized versions depending on the design and application.
Pressurized tanks may be equipped with components such as safety valves and pressure gauges depending on the design and specification. Documentation linked to, for example, PED and CE may be available where indicated.
Atmospheric tanks are often used in processes where pressure conditions are not relevant.
Applications in industry
Agitated process tanks are used in several types of industrial processes.
Examples of applications are food production, chemical industry, pharmaceutical related processes and water treatment where mixing or circulation of liquids can be part of the process.
The tanks are also used in processes where temperature control or homogenization is important depending on the application and operating conditions.
Technical options and equipment
Tanks can be equipped with, for example:
Different types of stirrers and mixing solutions
Engines and speed control
Temperature-related solutions such as sheathing or insulation
Inspection hatches and level measurement
CIP system for cleaning
Valves and process connections
Pressure monitoring in certain processes
The design varies depending on the model, specification and application.
Volume and capacity
Agitated process tanks come in many different sizes depending on the process and capacity needs.
Smaller tanks are used, for example, in pilot processes and laboratory environments, while larger tanks are used in production facilities with larger flows and batches.
Volume can influence factors such as agitator size, motor power and peripheral equipment needs depending on the application.
Advantages of agitated process tanks
Stirred tanks are often used in processes where liquids need to be kept homogeneous or in motion during operation.
The design can allow integration with different technical solutions depending on process requirements and operating conditions.
New and used agitated tanks
Processöverskott offers both new and used agitated process tanks in various designs and sizes.
Tanks may be equipped with different technical solutions depending on the model and previous use. Availability varies depending on stock status and specification.
Choosing the right solution
Stirred process tank selection is often based on factors such as fluid properties, viscosity, temperature, pressure conditions and process requirements.
Process surplus can provide information on different designs and technical options depending on the application and area of use.
Executive summary
Agitated process tanks are used in many types of industrial processes where liquids or process materials need to be mixed, homogenized or kept in motion.
Process surplus offers stainless steel tanks in stainless steel 304 and acid-proof 316 in various designs where technical solutions such as stirring, CIP, level measurement and temperature-related functions may be present depending on the specification and application.
