Benefits of Passivation and Electropolishing

Pickle passivation is the immersion of metal in a nitric-hydrofluoric acid bath. Pickled stainless material has a light matte appearance. Benefits include ease of sterilization and corrosion resistance.

Electropolishing is the immersion of metal in a charged bath of sulfuric and phosphoric acid. Benefits include ease of sterilization, improved cleaning properties, corrosion resistance and a mirror finish look.

Apache is a manufacturer of small and large vessels and food processing equipment. We can handle small parts or assemblies as large as our tanks that we build, with larger pieces possible with the use of fixtures or double dipping.

Side Agitated Vertical Tank Serves as Large Stock Pot in Sauce Processing Application

This side agitator was engineered to mix food products with a high percentage of solids and viscosity in the processing of soups, sauces, marinades and gravies. The 2500 gallon tank acts as a large stock pot as part of the manufacturing process.

On the left photo, the tank (shown horizontal during manufacturing) was equipped with a half pipe jacket, which was pumped with heated fluid as required by the application. On the right, the tank head shows fittings and man way entry.

Apache’s agitation, heat transfer and finishing technologies include:

  • Vertical and horizontal agitation capabilities
  • High shear, turbine, full sweep, scraping, counter rotating and baffled technology for mixing and blending
  • Dimple jackets, half or third pipe jackets, internal coils for heating or cooling applications
  • In-house passivation, pickle-passivation and electropolishing services
