Stainless steel mixing tanks are widely used in industries such as food, dairy products, beverages, chemical, daily chemical, pharmaceutical, etc. They are key equipment for achieving mixing, reaction, dissolution, homogenization and other processes. How to choose a suitable stainless steel mixing tank for different application environments? This article provides comprehensive selection references for you from the aspects of material, mixing material, capacity, mixing method, speed, sealing, and functional configuration.
Stainless steel material is an important factor in determining the corrosion resistance and service life of mixing tanks.
304Lstainless steel: suitable for industries such as food, beverage, dairy products, etc., it is the most common food grade stainless steel material.
316L stainless steel: containing molybdenum, with stronger corrosion resistance, suitable for chemical, pharmaceutical industries or materials containing salt, high acid and high corrosiveness.
If you are involved in the chemical industry or have higher requirements for corrosion resistance, it is recommended to choose SUS316L stainless steel mixing tank; Ordinary food processing can meet the demand by using SUS304L mixing tanks.
Before choosing a mixing tank, it is necessary to clarify the characteristics of your material, such as
Material status: liquid, solid-liquid, slurry?
Is the viscosity high or low?
Is it prone to sedimentation?
Do you need to dissolve or emulsify?
These are all factors that need to be considered, as material characteristics directly affect the type of stirring blade, stirring speed, power size, and whether heating, cooling, and other functional configurations are required.
● Capacity selection
The capacity of stainless steel mixing tanks can be customized according to demand, ranging from 50L to 50000L. Selecting appropriate capacity based on process batch and output planning can effectively improve production efficiency.
● Floor area size
According to the installation space, you can choose:
Vertical mixing tank: saves space and is suitable for most factory environments.
Horizontal mixing tank: suitable for low space or high viscosity materials, with more thorough discharge.
When planning the site layout, it is recommended to confirm details such as tank height, diameter, and platform space in advance.
The mixing system is the core of the mixing tank and directly affects the mixing effect.
● Mixing speed
Different processes require different stirring speeds, for example:
Low-speed stirring: suitable for ordinary mixing.
High speed stirring/high shear emulsification: suitable for emulsification, dispersion, crushing, and strong mixing.
● Mixing blade type (mixing method)
Common mixing blades include:
Paddle type (suitable for low viscosity materials such as milk, beverages, etc.)
Scraper type (suitable for high viscosity materials and prevents wall hanging, burning, and scaling)
Frame type (suitable for materials with high viscosity such as yogurt)
High shear emulsifying head (dispersed emulsification, suitable for dissolving sugars, CMC, pectin, etc.)
Choosing the appropriate blade type based on the characteristics of the process can significantly improve mixing efficiency.
The sealing structure of the mixing tank affects:
Is there any material leakage
Can a hygienic environment be maintained
Can it meet the requirements of vacuum or pressure
When choosing, attention should be paid to details such as mechanical seals, sanitary sealing rings, and can lid structures to ensure safety and production stability.
High quality stainless steel mixing tanks are not only reflected in their materials and craftsmanship, but also include:
1. Whether it has food grade/pressure vessel qualifications
2. Whether the welding process is qualified
3. Is the after-sales service comprehensive
4. Whether the accessories use branded products
According to the production process requirements, the following additional functions can be selected:
Jacket heating (electric heating, steam heating)
Jacket cooling
Single layer/insulation layer/jacket structure
Meet CIP online cleaning function (improve hygiene level, suitable for the food and pharmaceutical industry)
Instruments such as level gauges, thermometers, pH gauges, pressure gauges, etc
Mixing speed variable frequency regulation
The more matched the functions are, the better the process efficiency and product quality can be guaranteed.
After a comprehensive understanding of materials, material characteristics, capacity, mixing type, speed, sealing, and additional functions, we believe you can easily choose the appropriate stainless steel mixing tank for your process.
