APV Flex-Mix® Instant Series

High-Performance Powder-Liquid Mixing

The APV Flex-Mix® Instant Series is a high-performance mixer engineered for fast, efficient and hygienic powder-liquid high shear mixing in batch, inline continuous processes. Designed to reduce dust emissions, eliminate clumping and save time, it’s ideal for food, dairy, beverage and personal care applications.

Product Features

• Versatile configuration: Supports batch, inline continuous mixing setups
• Dust-free operation: Hermetically sealed mixing head minimizes airborne powder and product loss
• Consistent product quality: Delivers uniform dispersion even with challenging powders
• Compact and flexible design: Easily integrates into new or existing production lines
• Hygienic construction: Fully CIP and SIP capable to meet strict sanitary standards
• Efficient processing: Reduces mixing time and energy use with options for batch, inline over hydration tanks or closed continuous systems using vacuum powder transport

Operational Advantages

• High powder intake: Unique high-shear mixing technology ensures rapid powder incorporation
• Longer run times: Efficient air removal during mixing enhances product stability and equipment uptime
• Dust-free, closed operation: Supports continuous, enclosed production with reduced contamination risks
• Exceptional flexibility: Handles a wide range of powder-liquid formulations across industries
• Proven mixing principle: Powder is drawn into recirculating liquid by vacuum and homogenized through a high-performance mixer head adjacent to the tank

Theory of Operation

During vacuum mixing, powder is sucked in from a closed powder hopper or bag system. Using the vacuum level in the tank, the powder is washed out directly into the circulating liquid below the liquid surface; ensuring dust is not released into the surrounding atmosphere. The wet and dry phases of the process are thereby completely separated, reducing the risk of bacteria formation. A vacuum prevents air from entering the mixture, reducing undesirable effects such as oxidation, nutritional degradation, and discoloring. The resulting mixture flows through the system with minimal aeration, and can be directed to downstream processing without the need for holding tanks or additional mixing steps. The high shear pump is located at the side of the mixer, which gives added ergonomic benefits including easy access and a safe environment for maintenance.
