Mixers & Blenders
Stainless Tank & Mix (STM) designs and manufactures custom stainless-steel mixing systems for liquid, powder and combined batch applications. Our mixers and blenders are used across food, beverage, pharmaceutical, cosmetic and chemical manufacturing where hygiene, consistency and system reliability are essential. Each system is engineered for efficient shear performance, temperature control, dispersion and batch uniformity, with full integration into existing tanks, dosing systems, CIP processes and automation platforms.
Capabilities
STM provides a complete range of liquid and powder mixing solutions, from top-entry and side-entry agitators to high-shear and contra-rotating systems for complex emulsions. We also produce portable mixers, sanitary magnetic-drive units and packaged mixer assemblies for flexible plant use. Powder capabilities include ribbon blenders, paddle and plough mixers, and hybrid wet/dry systems for batching, coating and continuous processing. All systems are available with customised mixer geometry, drive configuration and process control options suited to the required batch size, product characteristics and production environment.
Design & Engineering
STM combines proven mechanical principles with advanced engineering tools to ensure reliable mixing performance. Mixers and blenders are modelled in 3D CAD for footprint planning and integration, with Finite Element Analysis (FEA) available for shaft sizing, structural integrity and vibration assessment. Key parameters such as impeller geometry, tip speed, torque and power draw are selected based on viscosity, particle size and desired shear characteristics. Engineering options include variable speed drives (VSDs), mechanical seals, bearing assemblies and full automation connectivity – delivering repeatable results and long-term operational reliability.

Construction & Materials
Mixers and blenders are built using 304, 316 or 316L stainless steel, with optional duplex alloys where required for corrosive or abrasive materials. Weld procedures follow sanitary and fabrication standards suitable for hygiene-critical environments.
Engineering options include:
• IMPELLER STYLES
Propeller, paddle, helical, turbine, ribbon, anchor and high-shear heads
• DRIVE ASSEMBLIES
• MOUNTING OPTIONS
• SURFACE FINISHES
Quality Assurance, Documentation & Traceability
STM applies the same QA principles used in tank fabrication to our mixer and blender projects. Documentation packages can include:
- Material certificates for wetted components
- Weld mapping and passivation records
- FAT procedures and test reports
- Electrical and mechanical commissioning documentation
Operating and maintenance manuals - ERP-controlled traceability via Odoo
Compliance & Hygiene
- CIP (Clean-in-Place) and COP (Clean-Out-of-Place) systems
- Sanitary and hygienic fittings (Tri-Clamp, DIN, SMS etc.)
- Low-turbulence designs for low-shear or sensitive products
- High shear systems for emulsions or colloidal dispersions
- Internal surface finishes can be specified to ≤ 0.4 Ra μm to minimise product retention, microbial risk and cleaning downtime.

Liquid Blending
Whether your product is a watery low viscosity product, a very thick high viscosity product or anything in between, Stainless Tank & Mix can fabricate a liquid mixer to suit your needs.
There are many different mixing solutions available, including the vessel that the mixer operates in which are set out below.
Powder Blending
There are many different powder blending solutions available, which are set out below
Stainless Tank & Mix also has extensive experience in associated equipment such as:
- Powder Transfer Equipment – Augers, flowveyors, vacuum transfer systems etc.
- Sieving Equipment – Rotary sieves, vibratory sieves
- Magnet traps
Ribbon Blenders
Stainless Tank & Mix have a range of standard powder blenders available that would suit a range of industries and applications.
Alternatively, our design and engineering team can design and fabricate a custom design where required.
Ribbon Blenders in particular are a tried and proven method of blending powders in large quantities for economical outlay
Plough Blenders, often known as Plough Shear Mixers, provide users with a more aggressive mixing action than Ribbon Blenders.
Whether working with powders, granules or pastes; the Plough Shear agitator imparts high energy and results in quick and thorough results, with a necessary trade-off in energy use.
The Stingray ASM is the ultimate blending machine particularly where the powdered product requires liquid additions.
Two attributes that make the Stingray ASM stand out is the ease of cleaning and the ability to mix down to 10% of its capacity.
Concrete Mixers from Stainless Tank & Mix are not for the construction industry - they have been designed and built specifically for the food and allied industries and come in two standard sizes - 2.2cuft (60 litres) and 3.5cuft (90 litres). The 3.5 cuft unit being the preferred choice.
