Vacuum mixer for liquids and semi-solids
Achieve precise mixing and homogenization of liquid and semi-solid formulations with this vacuum mixer, ensuring stable emulsions and optimal process control in demanding production environments.

Mixes and Reacts Liquids and Semi-Solids
The BACHMIX L from Bachiller is a versatile vacuum mixer and reactor designed for liquids and semi-solids, offering a comprehensive solution for processing in the pharmaceutical, cosmetics, and food industries. Featuring a unique combination of a slow anchor stirrer and high-shear rotor-stator emulsifier, it ensures fine emulsions and stable mixing even with medium viscosity products. This equipment accommodates customizable batch sizes from 150L to 1,000L, all controlled through a sophisticated PLC system with a user-friendly touch screen interface, ensuring precise and repeatable processes.
Ideal for applications requiring emulsification, homogenization, and vacuum processing, the BACHMIX L handles the production of products such as sunscreens, antibiotic formulations, and cosmetic creams efficiently. Engineered for versatility, it operates under vacuum and pressure, minimizing post-processing de-aeration and improving product consistency. The equipment conforms to cGMP and FDA standards, making it suitable for regulated industries, and is available with features like sanitary design, CIP/SIP readiness, and ATEX compliance for hazardous environments. The integration of a heating/cooling jacket enhances thermal management, reducing cycle times and energy consumption, while the robust stainless steel construction provides durability, corrosion resistance, and an easy-clean surface to maintain hygiene and minimize downtime.
