    From a cup of feed to a
    powder you can test.

    There are two gates. The bench test tells us how your material looks and how it dries. If it looks feasible, the pilot trial runs it on our P-10 dryer and makes a powder.

    We measure
    & oven-dry it

    A moisture balance gives the % solids. We then check the appearance of your feed on the tray. We learn a great deal about your product by simple observation.

    • Slides, crusty.
      Easy to dry.
    • Sticks, crusty top.
      Moderate.
    • Sticks, gooey.
      Needs formulation.

    Send 5
    gallons

    We schedule the run, repeat the bench test to confirm the material, and feed it to our P-10. We can dilute it, heat it or formulate it on site.

    We encourage you to attend the trial, and watch our dryer make your powder.

    Get your
    powder back

    We send you the powder and a complete report with photos. You will have enough powder to analyze it for viability, color, flavor (foods and nutraceuticals only!) or other characteristics.

    RUN DAY

    Pilot trial

    What a day covers: our P-10 dryer and operator running your material, adjustments on site, moisture testing of the powder, and the report. Five gallons is about one day of feed.

    We can help most customer types.

    Foods, nutraceuticals, pharmaceuticals and chemicals. These are the most common reasons to test.

    Freeze drying

    Maybe we can make an equivalent powder for one-fifth the cost.

    Stuck at
    low solids

    Less water in the feed means a dryer that costs less to buy and to run for the same throughput.

    Corrosive or
    abrasive feeds

    We can solve your corrosion or abrasion problem. For other chemicals, higher solids or better powder characteristics.

    “It can’t be
    spray dried”

    A product with fibers clogged at first. We added a little compressed-air assist on the spot to push the fibers through, and made a great powder.

    Quick answers.

    Foods, nutraceuticals, pharmaceuticals and chemicals. These are the most common reasons to test.

    Do I need to sign an NDA?

    No. If you buy a dryer, confidentiality terms are in the contract. If you want an NDA for the test, we’ll sign it.

    How much material does the pilot trial need?

    About 5 gallons. High-solids feeds dry fast, so we may ask for more. We’ll tell you the amount before you ship.

    When is a material not a fit?

    High-volume commodities, such as milk on a 30,000 lb/h dryer, are beyond our range. Very difficult feeds may need formulation first.

    Can I watch the test?

    Yes. You’re welcome to visit the lab in Mesa, take your own photos and videos, and talk with the engineer running it.

    Talk to us,
    then just send it.

    A short conversation before you ship helps us understand your material and what you want from it. The bench test is free, with no obligation.
