The System

Ziel's food safety technology uses RF photons to energize (activate) molecules in the host commodity and its pests, inducing thermal effects that lead to disinfection (pasteurization), disinfestation, enzyme inactivation and drying effects.

Ziel's partnership with STALAM, an Italian company that specializes in drying and thermal processing equipment, allows us to expand the adoption and implementation of RF technology in the food industry. Our products are custom made with the layout of your production facility in mind.

Ziel designs, builds and installs our processing lines with your requirements and product in mind. We will partner with you to design and build custom process systems that will best meet your goals.

The SENTINEL System is specifically designed for the treatment of high moisture commodities. Heat is generated directly within the product and does not rely on vaporization or slow conduction heating. SENTINEL allows for shorter processing times than conventional drying systems, which retain foods’ nutritional values and translates into increased production volume and significant energy savings. This system has the added benefit of eliminating pathogens and pests and is ideal for commodities such as prunes and dates.
