Stainless steel mixing tanks

Which mixing technology works best for my application?

Stirring vessels and mixing tanks differ primarily in the underlying stirring task and viscosity of the respective medium. Basic stirring tasks include homogenizing, suspending, dispersing, emulsifying and gassing, whereby the viscosity can vary from 1-600 millipascals (aqueous) up to 100,000 mPas.

Behälter KG offers agitators for all types of application, with the following agitators / impellers being most common:

• propeller stirrer: well suited for simple homogenization of aqueous substances, as a directly driven high-speed mixer (e.g. for fruit juice or spirits) or with lower speed though a geared motor for more gentle mixing (e.g. milk or dairy products)
• anchor agitator / frame stirrer: slow-speed, anchor-shaped agitator for highly viscous substances, e.g. as maturation tank or for products such as chocolate, toothpaste or polymer solutions
• blade stirrer: slow-speed geared agitator with blade-shaped agitator elements, for a gentle homogenization of low- to medium-viscous products, such as mayonnaise, coatings, shampoo or pudding
• oblique blade stirrer: 4-blade impeller element, installed at a 45° angle, suitable for homogenizing, dispersing, suspending and degassing with a comparatively high power input
• dissolver: support plate with tooth-like circumferencing elements, the dissolver generates high shear forces and is suitable for dispersion, emulsification or wet milling (e.g. printing inks, pigment pastes or plasters)
• cup stirrer: slow-speed cone shaped cups, particularly suitable for the gentle homogenization and degassing of aqueous to viscous substances, without shear forces (e.g. soap, oils, lotions, shampoo)
• jetstream-mixer: fast-running rotor-stator agitator, for very fast homogenization without air entry and sedimentation
• Magnetic stirrer: installed in the bottom of the tank, designed for aseptic mixing applications and very small amounts of product to be mixed (e.g. eye drops, active ingredients, laboratory tests)

Brand-new mixing tanks- standardized product groups

Behälter KG has developed various standardized mixing tanks over the years, which we usually have available pre-produced directly from our stock. These stirring tanks primarily include the following standardized product groups:

• SDE-Flexmix: mobile mixing tanks : mobile stirring tanks with a volume of 500 to 1000 liters (also heated / coolable)
• FIT-Storemix: jacketed mixing tanks : heated / coolable mixing tank with a volume of up to 10,000 liters
• AIT-Containermix: agitator containers : flexible stirring container with a volume of 500 - 1500 liters (also heated / coolable)

We have extensive technical documentation for our standardized stirring vessels and of course also offer you the necessary spare parts over a long term period. If required, we can also adapt our standardized stirring vessels to your customer-specific requirements!

Benefits of second-hand (used) stainless steel mixing tanks

Our large selection of “made in Germany” used mixing tanks and stirring vessels offers an instantly available premium production machine, at significantly reduced budget.

Especially with complex mixing requirements such as coaxial agitators, anchor agitators with wipers or agitators with mechanical seals, used agitator tanks are often available for a fraction of a brand new tank. All of our second-hand stirring tanks have been used until recently – we can gladly provide you with detailed pictures or additional information if you want to better understand the condition of a specific product. As our used stirring tanks come primarily from the German-speaking countries, they were built almost exclusively by well-known brand manufacturers - this can also be seen in the excellent material processing welding quality.

Our used stainless-steel mixing tanks come from a variety of industries - classic areas of application are food processing (e.g. chocolate, yoghurt), beverages (beer, fruit juice, mineral water), chemicals (paint, polymers) and pharmaceuticals (cremes, herbal medicine). We will always clearly state the previous operational purpose for our second-hand machinery, so that the suitability for a new application can be easily determined.

Brand new “made to measure” mixing tanks

For customers or plant engineers with very specific requirements, we offer custom-made stirring tanks at an attractive delivery time and a good price / performance ratio.

We would be happy to make you an offer according to your specifications, simply contact us using our  contact form .

Our production spectrum covers the whole range of stirring technology, paired with 50 years of experience in stainless steel tank construction. Configuration options include, for example:

• Vertical mixing tanks made of stainless steel
• Horizontal mixing tanks made of stainless steel, installed on legs or on saddles
• Temperature controlled (heated / coolable) tanks with agitator or reactors made of stainless steel
• Insulated stainless steel stirring vessels
• Pressure-resistant stainless steel reactors

In all custom-made projects, the stirring technology is tailored to your process requirements. For low-viscosity applications, for example, we can offer inexpensive high-speed propeller agitators. However, we are also experienced in more complex areas, such as anchor agitator tanks or process tanks with multiple agitators.
