Sanitary Process Tanks

Apache’s in-house processes and expertise in compliance and surfaces finishes, gives Apache a competitive advantage in providing Sanitary Process Tanks. Our sanitary tanks are found in the food, beverage, pharmaceutical, biotechnology, water filtration and health and beauty industries.

We have provided cook tanks, mixing tanks, heat exchangers and storage tanks with sanitary design requirements. We have also manufactured tanks and vessels for WFI (Water for Injection) and CIP (Clean-in-Place) processes.

Apache also has in-house capabilities for passivation and electropolishing stainless finishes, if required for the application.

  • Two Local Companies Work Together to Solve Need for Increased Production and Storage Posted 9 months ago
    Brakebush Brothers, a leading processor of chicken products, worked with Apache Stainless Equipment Corporation to design, fabricate and deliver a new 20,000 gallon fresh oil tank for their Westfield, Wisconsin plant.   David Meyer, Utilities Manager at Brakebush, needed a new storage tank to keep up with production demands and chose Apache Stainless for it’s reputation as a quality manufacturer of stainless tanks and expertise in heat transfer surfaces and sanitary tank finishing.   The 13’ 6” diameter tank is 33’ feet tall and replaces an 8,000 gallon tank that will be relocated to another Brakebush plant.   David Foulkes, Sales Manager for Apache, worked with Brakebush and Apache’s tank team to provide the new tank with specifications to include a containment shell, steam dimple jacket, insulation and protective shroud with controls to monitor and adjust the heat temperature of the oil, especially during the winter months in Wisconsin, as well as the required flow into the plant for production operations.   The Brakebush Westfield, Wisconsin plant has a production facility of over 500,000 sq. ft. with state of the art cooking operations. Westfield is also ...
  • What is the difference between pickle passivation and electropolishing? Posted last year
    The main difference between pickle passivation and electropolishing is the appearance and RA (roughness average) of the stainless material. In the photo, an electropolished sample is shown above a pickle passivated sample. The pickle passivated sample has a white appearance, while the electropolished sample has a mirror-like, shiny finish. Pickle Passivation is the immersion of metal in a pickling bath such as nitric-hydroflouric acid. The process removes metal such as impurities and heat marks from welds. Electropolishing is an electro-chemical process that removes surface material from stainless steel. The process typically starts with an immersion of the component into a controlled bath of electrolyte that is charged with a DC power supply. Apache’s RA tests show improvements up to 50% smoother, depending on the material. Do you have more questions like this one? Check out the Contract Manufacturing FAQs page.
