Why does Highland Fresh Technologies require application of Selectrocide®
high-purity chlorine dioxide in a brush washer process instead of a dump tank?
The primary function of a sanitizer used in a recycled water system like a dump tank is to kill the organisms that accumulate in the water. While Selectrocide biocide is effective in killing microbes in water, the dip or recycled dump tank method of application is not the best for actually reducing the levels of spoilage microbes on the fruit surface. Microorganisms attach themselves to fruit surfaces, and are thus very different than soil or leaf debris that may be sitting loosely upon the fruit. Brush washing to scrub the fruit surface helps expose organisms that are more firmly attached to the fruit. Through a combination of physical scrubbing action and Selectrocide biocide action, brush washing can provide a more consistent reduction of spoilage microbes on fruit surfaces. Another benefit of applying Selectrocide solution in the brush washing process is that the biocide is able to minimize the potential for cross-contamination in this step. Brushes can simultaneously remove and spread field contaminants that increase decay. Selectrocide high-purity chlorine dioxide minimizes the potential for brushes to increase decay through cross contamination.
Can I use Selectrocide solution in my tomato dump tank?
The State of Florida has recently adopted new rules governing the management of tomato dump tanks. These rules require the use of chlorine (typically chlorine bleach) within specific operating parameters whereby concentration, solution pH, and temperature of the water must be closely monitored. Highland Fresh Technologies believes the most beneficial and cost effective way to utilize Selectrocide solution is in the brush washing process, rather than the dump tank. In many instances, our customers utilize Selectrocide spray in the brush washer after the tomato dump tank.
Why do I have to sign a purchase agreement to use the Selectrocide application system?
The Highland Fresh Technologies purchase agreement defines warranty items for our patent pending application system. In a few cases, clients have modified the application system after installation and significantly altered the manner in which the unit operates and voided their warranty. The purchase agreement is necessary to ensure both parties understand the terms and conditions of sale.
