Systems and methods for sanitizing produce in an acidic bath

This invention describes a way to clean produce using a special acidic liquid. It works by first combining water with two different acids to make a strong concentrate. This concentrate is then diluted to the right strength, and the produce is washed with this diluted solution. The claims specifically detail preparing this concentrate in a mixing tank and then transferring it to a holding tank.

Why it matters: Filed before the widespread adoption of affordable, precise industrial automation and sensor systems. These advancements now make the claimed method of preparing and diluting the acidic solution significantly more consistent and cost-effective.
