Pneumatic High Shear Homogenizer Reactor 50-500L, Stainless Steel, Movable Batch Mixing Tank for Cosmetics

Equipment Overview

This pneumatic high shear homogenizer reactor is built for batch processing in the 50 to 500 liter range. It combines a stainless steel mixing tank, a pneumatic lift system, and a high shear homogenizing head into one movable unit. The design is straightforward: you get intense mixing, emulsifying, and dispersing capability without the need for permanent installation or complex piping.

The tank is mounted on casters, which makes it practical for facilities that run multiple products and need to move equipment between production bays. The pneumatic lift raises and lowers the homogenizer head, so you can clean the shaft and rotor easily between batches. That matters more than most buyers expect, especially when you are switching from one formulation to another.

Materials and Manufacturing

We use 304 or 316L stainless steel for the product contact surfaces, depending on your process requirements. 316L is the safer choice for acidic or chloride-containing formulations, while 304 is fine for most cosmetic and pharmaceutical emulsions. The inner tank surface is mirror-polished to Ra ≤ 0.4 μm, which helps with cleaning and reduces product adhesion.

Welds are fully penetrated and ground smooth. There are no crevices where product can hide. The vessel is designed for atmospheric pressure operation, but we can add a vacuum or light pressure rating if your process requires it. The heating and cooling jacket is available in either electric heating or steam heating, with cooling via cooling water circulation.

Mixing and Homogenizing

The high shear homogenizer operates at speeds up to 2800 rpm, depending on the model. This is not a simple stirrer. The rotor-stator design creates intense shear forces that break down droplets and particles to the micron level. For a typical cosmetic cream or lotion, this means a stable emulsion without the need for multiple passes through a separate mill.

The anchor stirrer, if included, runs at a lower speed to keep the batch moving and to scrape the heated wall. That combination is useful for products that thicken during cooling, because it prevents localized overheating and ensures uniform temperature throughout the batch.

Technical Specifications

Applications

This reactor is commonly used for cosmetic creams, lotions, shampoos, gels, and sunscreens. It also handles pharmaceutical ointments, chemical dispersions, and food emulsions. The movable design is especially useful for small-batch production, pilot plants, and multi-purpose lines where you do not want to dedicate floor space to a fixed vessel.

FAQ

Can I process a high-viscosity product? Yes, but the anchor stirrer is recommended for products above 10,000 cP. Tell us your viscosity range so we can size the motor correctly.

How do I clean the machine between batches? The homogenizer head lifts pneumatically, giving you full access to the shaft and rotor. The tank interior is polished and drainable. Most customers use a CIP spray ball or manual washdown.

Do you offer vacuum operation? We can add a vacuum port and a sealed lid for deaeration or for processing under vacuum. Let us know your requirements.

What about the mechanical seal? We use a single or double mechanical seal depending on the solvent and pressure conditions. For solvent-based formulations, a double seal with a barrier fluid is the safer option.

How to Order

To get an accurate quote, send us your process details: the material you are processing, its chemical composition and concentration, batch volume, operating temperature, pressure requirements, and the mixing effect you expect. Include viscosity and solids content if you know them. With that information, our engineers can recommend the correct tank configuration, motor power, and optional features.

Contact us with your requirements, and we will provide a configuration and pricing that fits your production line.
