JVNW Mixer division

JVNW, Inc. constructs mixers for vessels and tanks. JVNW mixers aid in heat transfer, mix ingredients or adjust the product using gas dispersion or emulsification.

The JVNW Mix Tank: Where all components are perfectly matched for efficiency and performance. Cleaning devices reach every corner and do not interfere with shafts and impellers. Instrumentation is properly located to avoid false readings. Heat transfer jacketing is sized for batch loads or zoned for flexibility.

The whole process from shaft sizing to seal design is more effective when it comes from one source, and that source is JVNW. We combine tank fabrication expertise with our Mixer Engineering Department to offer a wide range of experience in agitation technology.

 JVNW Tank Technology + JVNW Mixer Technology = The Ultimate Mix Tank

  • Faster start-ups
  • Mixer-to-tank testing
  • Pre delivery assembly
  • No mismatches
  • Quicker delivery
  • Lower start-up costs

The following mixer designs are JVNW’s standard models. Custom designs are also available to meet your specific needs. If a higher viscosity product is required than listed in the process parameters, please consult the factory.

Engineering Analysis

Sanitary Design Experience: JVNW engineers are well acquainted with 3A, ASME standards, and all applicable codes. The requirement to pass spray-ball coverage tests for mix vessels gives JVNW engineers a unique insight into CIP performance on mixers.

JVNW Rheology Lab

The Mixer Test Lab uses the principle of rotational viscosity measurement. A spindle is immersed in the fluid sample and the torque resistance is measured at a constant speed.

The programmable viscometer will accurately (+ or – 1%) measure fluids with viscosities from 15 ­ 6,000,000 cps (centipoise). On-site analysis is a service offered by JVNW. NIST traceable viscosity standards, data capture and retention capability (including temperature) are also provided.

Our Mixer Lab will:

  • Define the fluid characteristics of your product
  • Assist in the development of new products
  • Quantify and measure JVNW mixer performance
  • Perform on-going scientific research and development

The rheology of the fluid is important, as well as the desired mixing levels, utilities available, time constraints, and any unusual consideration such as, explosive atmospheres, foaming or other unique mixing characteristics.

Offset Mount Dual Motion Mixer

JVNW’s Offset Mount Mixer is used in applications where more than one mixing action is required, and for processors who require the flexibility to address a wider variety of products. The most common configuration is a center mounted scraper with an offset turbine style mixer less the steady bearing. Other configurations include a center sweep style mixer and substituting a high shear style mixer for the offset turbine.

This style of mixer is constructed where one mixer is concentrically mounted and one is off-set, allowing for an optional third mixer. A sanitary steady bearing is used to support the center shaft, eliminating the bending moment caused by offset mounting. A rigid cross arm stiffens the scraper frame to handle the most severe service. The most common configuration is a scraper/turbine combination. For additional product movement in high viscosity applications, multiple flow impellers are combined to ensure complete product movement with no dead zones.

JVNW Custom

JVNW offers a wide variety of mixing vessels, including: Sanitary Ribbon Blenders, Scraped Surface Horizontal Blenders, Dual-Motion Scraped/Ribbon Blenders, Complete Skidded Mixing Systems and many others. JVNW also fabricates a wide variety of special purpose mixers such as mayonnaise emulsifiers, saute fryers, and gate mixers for shortening.

JVNW Tele-Tilt Mixer (pictured left)

Problem met solution when JVNW’s creative engineering team crafted the telescoping shaft to accommodate a hinged top, thus requiring minimal clearance. The hinged shaft allows for disassembly of shaft and impellers without pulling drive from vessel. Seal assembly is attached not to mixer shaft, but to the quill shaft, for ease of maintenance and testing.
