Use of stainless steel tanks in food production
In food production, stainless steel tanks are used for storing, mixing and handling both raw materials and finished products. Hygienic requirements and controlled processes place high demands on materials and construction.
Stainless steel 304 and acid-proof 316/316L tanks are commonly used due to their corrosion resistance and suitability for food applications. The choice of material depends on the characteristics of the product and requirements for cleaning and hygiene.
At Processöverskott we have both new and used tanks in different sizes, from about 100 liters up to 250,000 liters. The tanks vary in design depending on construction and previous use, and many are available for quick delivery depending on stock status.
The tanks are used in several types of food processes, such as handling milk, beverages, fermented products and other ingredients with high hygiene and quality requirements.
Function and structure
Stainless steel tanks in food production are used for storage, mixing, fermentation and temperature-controlled processing. Tanks can be cylindrical or conical and placed horizontally or vertically depending on the product and process. They are often equipped with inspection hatches, level gauges, valve connections and CIP systems that contribute to hygiene and facilitate cleaning between batches.
Materials and construction
In food production, tanks made of stainless steel 304 or acid-proof 316/316L are used depending on the product’s properties and hygiene requirements. Stainless steel 304 is common in many food applications, while acid-proof 316/316L is used when the contents have higher requirements for corrosion resistance, for example in the case of acids or salts.
The construction of the tanks is normally welded, and the surface finish can vary depending on hygiene requirements. Common finishes include polished or satin, adapted to facilitate cleaning and handling in the process.
The choice of materials and surface treatment are important factors to reduce the risk of contamination and to cope with regular cleaning and disinfection in food applications.
Pressurized and atmospheric solutions
In food production, both atmospheric and pressurized tanks are used depending on the requirements of the process. Atmospheric tanks are common for storage without overpressure, while some applications, such as fermentation or carbonation of beverages, may require pressurized solutions.
Pressurized tanks are designed to handle overpressure and, depending on the design, may be equipped with, for example, safety valves and pressure monitoring. Equipment and specifications vary from one tank to another and are adapted to the process and application.
For pressurized tanks, specific requirements apply under current regulations, such as the PED Directive, and any inspection is carried out by an accredited inspection body.
Applications in food production
- Storage of raw materials such as milk, oils and acids.
- Mixing ingredients for finished products such as drinks and sauces.
- Fermentation of products such as yogurt, beer and wine.
- Temperature-controlled processing of chocolate, butter or liquid sugar.
- Hygienic storage of finished products before packaging.
Technical options and equipment
- Stirrers: mechanical or magnetic for homogeneous mixing.
- Temperature jacket for heating or cooling.
- Inspection hatches, level gauges and CIP systems.
- Valves and pump connections adapted for food standards.
- Automation and PLC control for process monitoring.
Volumes and capacity
Process Surplus offers stainless steel food tanks in volumes from 100-250,000 liters. Smaller tanks are often used in pilot plants or for specialty products, while larger tanks are used in large-scale production. Volume affects placement, insulation and equipment sizing, as well as how many batches can be handled simultaneously.
The benefits of stainless steel in food
- Corrosion resistance and long service life.
- Hygienic surfaces that are easy to clean and sterilize.
- Resistance to acids, bases and temperature variations.
- Flexible design that can be adapted to the product and process.
- Low maintenance costs and long-term operating economy.

Processöverskott has a wide stock of new and used stainless steel tanks for food production. The inventory covers different volumes, materials and pressure ratings, enabling fast delivery and short lead times. The right tank type can be selected directly from stock without long waiting times.
Choosing the right solution
When choosing a stainless steel tank for food production, it is important to consider the product characteristics, volume, temperature and hygiene requirements. These factors influence the type of tank and design that is suitable for the process in question.
Technical options, such as agitation, CIP systems and possible pressure classification, may vary depending on the application and production requirements.
Processöverskott has both new and used tanks in various sizes and designs. Available information about the specifications of the tanks can be used as a basis for choosing a solution that suits the current process.
Executive summary
Stainless steel tanks are used in food production for storing, mixing and processing ingredients and finished products. With high hygiene, corrosion resistance and flexible construction, they can be customized for different volumes and processes. Process Surplus offers both new and used tanks in volumes ranging from 100-250,000 liters, enabling fast delivery and efficient production planning.
Frequently asked questions about stainless steel tanks in food production
How are stainless steel tanks used in food production?
Stainless steel tanks are used for storage, mixing, fermentation and processing of ingredients and finished products. They are hygienic, corrosion-resistant and can be equipped with agitators, temperature jackets and CIP systems. The tanks contribute to consistent product quality and stable processes in production.
What materials are used in food tanks?
Stainless steel 304 and acid-proof 316/316L are the main materials used in food tanks, depending on the product’s characteristics and hygiene requirements.
Stainless steel 304 is common in many food applications, while acid-resistant 316/316L is used when the contents have higher corrosion resistance requirements, such as acids or salts.
These materials are well adapted to food production thanks to their resistance to corrosion and their suitability for cleaning and hygienic processes.
Which processes require pressurized tanks?
Pressurized tanks are used in fermentation, beverage carbonation or other processes where pressure control is necessary. Safety valves and pressure monitoring protect the product and personnel while keeping the process controlled and reproducible.
What technical options are common?
Common options include mechanical or magnetic stirrers, temperature jacketing, CIP systems, inspection hatches and level gauges. Valves and pump connections can be customized for hygiene standards and production requirements, as well as automation systems for process monitoring.
How to choose the right stainless steel tank for food?
The choice of stainless steel tank for food depends on several factors, such as product composition, volume, temperature and hygiene requirements. These parameters influence the type of tank and material suitable for the application.
The design of the tank, as well as any optional features such as agitation and cleaning-in-place (CIP) systems, may vary depending on the requirements of the process and how the tank will be used.
