The Walker Model PZ processor with the sloped reverse dish bottom head is a multi-purpose process tank with applications in the dairy, beverage and food processing segments.  The design provides good product drainage and is suitable for CIP.

The PZ sloped bottom, side outlet processor meets national and United States Public Heath Service requirements and the 3A Sanitary Standards for batch processors.

The side and bottom sweep agitation provides gentle but complete mixing and blending with fast heating and cooling.

The stainless steel heat transfer jacket, covering the sidewalls and bottom, may be divided into 3 or 4 (depending on size) separately controllable zones for maximum efficiency, flexibility and control when processing partial batches. The heat transfer jacket is designed for operating pressures up to 100 psig @ 320°F as standard; higher operating pressures and ASME & CRN code stamping are available.

The Model PZ is available in several different configurations including:

  • Standard atmospheric mixing and blending processor
  • Sealed agitator port for pressure and/or vacuum processing
  • Batch pasteurizer with thermal wells in the air head space for temp measurement and leak detect valves.

Standard sizes from 200 to 3000 gallons and larger, however vessels as small as 10 gallons and as large as 10,000 gallons have been fabricated for certain applications.

Other options include choice of material (304 or 316L), port configurations, access ladder and more.

The unit is a multi-purpose processor providing mixing and blending with fast heating and cooling. The stainless steel heat transfer surface covers the sidewalls and bottom and is divided into 3 or 4 (depending on size) separately controllable zones for maximum efficiency, flexibility an control when processing partial batches.
