Radio Frequency for Nuts & Seeds
Developed in partnership with STALAM, the global leader in Radio Frequency technology, the APEX 85 effectively reduces Salmonella by a 3 to 5 log kill without impacting product sensory qualities.
Why Radio Frequency is Superior
Contrary to conventional thermal processing, RF penetrates evenly throughout a product and the process final temperature can be precisely controlled. It is also an organic, non-ionizing process.
3-5 Log Kill Reduction
Designed and manufactured in partnership with the global leader in radio frequency technology, STALAM, the Apex 85 combines the precision of radio frequency technology with Ziel’s proprietary process solutions to effectively eliminate Salmonella, E. coli, and other microbial pathogens in nuts and seeds. APEX 85 easily integrates into automated processes and effectively reduces microbial pathogens without the use of chemicals, ionizing radiation, or steam, making a superior application for food products.
RF works by creating an oscillating electromagnetic field between two electrodes in the APEX 85’s processing chamber. Operating at a 27.12 MHz frequency level, polar water molecules contained in the natural moisture of the product rotate 27 million times per second, generating friction and thus the heat necessary to kill microbial pathogens. The long radio wave profile penetrates uniformly throughout the product, creating ‘volumetric heat,’ as opposed to traditional thermal heating.
Easy to Operate
APEX 85’s HMI user interface consists of easy-to-use menus of preprogrammed processing recipes, developed by Ziel on-site with your team. The system monitors the progress and temperature of each treatment to provide real-time user feedback. Data logs are generated automatically to assist in quality control monitoring and reporting. Optional remote monitoring and software upgrades are available via a standard internet connection.
