Powder mixers
Raise process efficiency, product quality and yield while reducing total cost of ownership with Alfa Laval powder mixers. A combination of pump and powder-dissolving technologies makes possible quick, efficient powder dispersion, wet and dry ingredient blending, and the transfer of the homogeneous powder-liquid mixture for onward processing. A single electric motor drive enables powder mixers to cut energy costs by up to 75% compared to other powder mixers.
Increase mixing efficiency and energy efficiency while reducing total cost of ownership
- Boost yield thanks to quick and efficient blending of wet and dry ingredients into a homogeneous mixture
- Increase process and product flexibility, easily handling various formulations with different viscosities, densities, and volumes
- Cut process time, emissions and installation, energy, raw material, and maintenance costs
- Improve process flexibility by leveraging the mixing and cleaning capabilities in a single unit
- Fast return on investment and low total cost of ownership due to less waste and a more sustainable use of resources
Alfa Laval powder mixers increase mixing efficiency and productivity while reducing total cost of ownership. A single electric motor drive enables the high-shear mixers to blend a wide variety of product formulations.
The mixers draw powder into the unit while simultaneously pumping the resulting powder-liquid mixture at pressures of more than 4 bar. When used with a rotary jet mixer, the powder mixers may also be used as part of an efficient cleaning-in-place (CIP) system. Powder mixers are available as stationary units and mobile units.
How does powder mixers work?
A two-stage inline powder mixer comprises a two-stage pump with a rotor-stator, a funnel, and an injector. This high-shear powder mixer machine is typically integrated into a circulation loop and connected to a batch tank. In the first stage, the powder mixer circulates the liquid ingredients through the tank. Powdered ingredients are then added through a funnel. A valve under the funnel opens, and the injector positioned under the valve creates vacuum conditions in the funnel outlet, drawing the powder into the rotor-stator and pre-blending the powder and the liquid. The rotor-stator (single rings) creates the main shear, efficiently blending powder and liquid into a homogeneous mixture using advanced powder blendi techniques. In the second stage, the pump’s impeller creates the final shear and transfers the mixture into the tank under high pressure. A portion of the powder-liquid mixture is recirculated through the injector back to the first phase. The liquid flow in the injector creates vacuum conditions in the funnel outlet, enabling dynamic suction of the powder into the liquid. After mixing has been completed, the powder mixer may be used as a discharge pump or a Cleaning-in-Place (CIP) recirculation pump to clean the tank when used with a rotary jet mixer. For specialized applications, an industrial powder mixing machine such as the Alfa Laval powder mixer or a powder machine mixer can further optimize the process.
