Hybrid Powder Mixer
The Alfa Laval Hybrid Powder Mixer is a dual-stage induction and dispersion system that quickly and efficiently disperses and mixes powders into a liquid stream. Versatile, cost-effective and easy to use, this inline, high-shear mixer produces homogeneous products at high yields and with minimum power consumption. The mixer is highly suitable for industrial applications, where process hygiene is critical.
Versatile hybrid powder mixer for various powder-liquid blending duties
- Low installation costs using a single, highly efficient unit for mixing and Cleaning-in-Place (CIP)
- Easily handles various powder particle sizes and liquid viscosities to achieve consistent, quality formulations
- Shorter processing time and higher yields due to fast, efficient mixing of high dry matter concentrations
- Reduced maintenance costs due to low spare parts inventory and service requirements
Ensure quality mixtures and reduce processing times with the Alfa Laval Hybrid Powder Mixer. The integrated process design boosts yield and promotes sustainable use of resources. Unmatched reliability and mixing efficiency make it suitable for powder induction, mixing and dissolution in industries that place high demands on hygiene and ease of cleaning, including food, dairy, beverage, biotech and home and personal care.
This inline high-shear mixer ensures gentle product handling, high dynamic shear, and complete powder dissolution. It simultaneously pumps the process mixture onward and speeds batch turnover through effective Cleaning-in-Place.
In combination with an Alfa Laval Rotary Jet Mixer, the Hybrid Powder Mixer is a critical component of a highly efficient cleaning-in-place (CIP) system. The powder mixer is available as a stationary or as a mobile unit.
Construction
The Hybrid Powder Mixer S15 and M15 is comprised of a two-stage pump with one rotor-stator stage and one pump stage fitted with a motor with a frequency converter. A funnel is used for introduction of powder through an injector system. The construction is mounted on a stainless steel frame.
Operating principle
The two-stage inline Hybrid Powder Mixer is installed in a circulation loop connected to an existing batch tank. This user-friendly mobile unit has a built-in table to facilitate handling heavy bags of powder. The table easily slides into position for convenient placement of the bags during mixing and also functions as a lid to cover the funnel when it is not in use. Operation is easy because the operator only needs to control one valve during mixing. Cleaning-in-place is just as easy.
Stage 1
After adding liquid ingredients to the tank, the Hybrid Powder Mixer circulates the liquid over the tank. To provide additional high-efficiency mixing in tanks with volumes larger than 1 - 2 m³, it is recommended to install the Alfa Laval Rotary Jet Mixer in the tank.
After powder is added in the funnel, the valve under the funnel is opened. This is the only valve that the operator must control during mixing. The injector positioned under the valve then creates an under pressure in the funnel outlet, drawing the powder into the rotor-stator and blending the powder and liquid into a homogeneous mixture.
Stage 2
An impeller pumps the powder-liquid mixture back to the tank while part of the powder-liquid mixture is sent through the injector back to Stage 1.
The liquid flow in the injector creates the under pressure in the funnel outlet, which enables the dynamic suction of the powder into the liquid.
Cleaning
After mixing is complete, the Hybrid Powder Mixer may be used as a discharge pump or, when used with the Alfa Laval Rotary Jet Mixer, as a CIP pump to clean the tank interior.
