Can Commercial Ozone Vegetable Washers Really Remove Pesticides?

Can commercial ozone vegetable washers really remove pesticides? Many users are skeptical. CHINENG explains below.

Working principle

Units combine ozone oxidation foam, circulating surf wash, and boosted high-pressure spray to separate soil and debris. Continuous spray or nozzles let operators adjust flow to load and soil level.

Can they remove pesticides?

1. Tests often show removal of up to about 85% of certain residues, notably compounds such as methamidophos and dichlorvos on produce.

2. Versus home units, commercial machines offer higher power, stronger rinse, and better residue reduction.

3. No chemical additives—high-pressure rinse plus ozone that breaks down toward oxygen helps cut cost.

4. Pesticide chemistry varies; a single-mode sanitizer cannot remove every residue on every vegetable at peak efficiency.

Why does foam appear?

Many foods foam naturally. Saponins act soap-like in water. Beans and grains often contain them—soy milk foam is a familiar example, and processors may add antifoam agents.

Summary: commercial washers can meaningfully reduce residues such as methamidophos and dichlorvos. Cooking (stir-fry, steam, boil) further lowers risk. Follow the CHINENG website for more equipment knowledge.
