The Vorclone Scalder Filtration System is a non-chemical intervention designed to filter and clean scalders, significantly reducing the microbial load on poultry carcasses.

Solids and sediments that accumulate in the scalder during processing can lead to cross-contamination and increase the microbial load on carcasses, explained Daniel Lehmkuhl, Safe Foods Cooperation Product Manager, at the 2022 Poultry Tech Summit.

“The scalder is often ignored. We really have not had success in making a microbial impact there. Standard interventions are not great in application because they dissipate and there is a large amount of organic matter left over,” he said.

How it works

The Vorclone Scalder Filtration System recycles the water in the scalder, creating a recirculation loop that removes the contaminants and reduces the microbial load before moving the water back into the tank.

The non-chemical intervention uses physics to remove the contaminants from the scalder into the discharge tray and down the drain without any moving parts. It can complete up to five complete recirculation loops an hour on a 2,000-gallon tank.


“There's no filters that have to be cleaned out because the waste is discarded through a liquid solids separator and moved straight to the drain without having a lot of manual labor involved,” he stated.

During a research study involving the filtration system, Lehmkuhl found that the process could reduce the scald water’s Enterobacter load by 0.15 logs per hour and turbidity by over 10 nephelometric turbidity units (NTU) per hour when compared to the control system. Reducing the organic loading in scalders decreases pathogen prevalence during hot rehang while reduce the amount of sanitation labor needed, he added.

Lehmkuhl said that Safe Foods is currently seeking partners to test the Vorclone Scalder Filtration System on a larger scale.

Attend the 2023 Poultry Tech Summit

The Poultry Tech Summit is the only event of its kind that connects researchers and entrepreneurs with poultry sector technology experts, financiers, venture capitalists and producers looking for new projects and investments to fund. Since its 2018 inception, this unique conference has facilitated and fast-tracked many pioneering ideas into adoption for the benefit of the poultry supply chain.

Details on the 2023 Poultry Tech Summit will be released in Spring 2023.
