Vacuum mixer reactor for liquids and semi-solids
Achieve precise mixing and emulsification of complex liquid formulations with this versatile vacuum mixer reactor, designed to handle high-viscosity products while ensuring uniformity and stability under variable pressure and temperatures.

Mixes, Reacts, and Emulsifies Liquids and Semi-Solids
The Bachmix Multifunction from Bachiller is a high-precision vacuum mixer and reactor designed for handling liquids and semi-solids in demanding industries such as pharmaceuticals, cosmetics, and fine chemicals. This equipment excels in processes requiring precise mixing, homogenization, and emulsification, thanks to its coaxial mixing tools and high shear rotor-stator agitator. With capacities ranging from 150L to 5,000L, the unit supports operations under vacuum and pressure up to 3 bar(g), optimizing product de-aeration without additional steps. It features a PLC control system for full process automation and integration, allowing for seamless supervision with perfect traceability of fabrication parameters. Its robust design includes a heating/cooling jacket, sanitary construction meeting cGMP, FDA validation, and ASME VIII compliance, making it suitable for complex processing environments. The stainless steel construction with mirror polish ensures durability and easy maintenance, complemented by an integrated CIP/SIP system for efficient cleaning. Customization options are available, including versions for ATEX zones and software for product recipe creation, ensuring the equipment meets specific production needs.
