Gerlach et al., (17) in a 1-week in vivo study, did not observe a bleaching effect with a prerinse containing HP.
Prerinse solutions generally are not recovered and reused because they're heavily laden with solids loosened with water circulated under high pressure.
"It's more than one but less than 30 usually, and it depends on the nature of the product being processed, the quality of the prerinse, the quality of the CIP system itself, and also the velocity the solution moves through the equipment," he says.
Another ECM for saving hot water is to install low flow prerinse nozzles with a flow rate of 1.2 gpm (0.076 L/s).
(A full CIP cycle lasts about two hours and consists of a prerinse, an alkaline-based cleaning application, a rinse and a wash with acid sanitizer.)
The lauter tanks, for instance, are cleaned with a prerinse, a 2 percent sodium hydroxide solution, and a final rinse.
The three-part whitening system consists of a prerinse, bleaching gel and polishing cream in all three SKUs.
For a typical analysis, the following procedure was used: 3-min prerinse with the running buffer (20 psi, 138 kPa), 2- to 5-s injection of the sample at low pressure (0.5 psi, 3.4 kPa), 1-s pressure injection of running buffer, separation at +10 kV (37 AA), 1-min rinse with the washing buffer, followed by 1 min with 0.1 mol/L NaOH.
A typical CIP sequence would be: prerinse; clean; rinse; acid rinse or wash; rinse; sanitizer.
The system consists of a prerinse that helps remove surface film, a whitener gel containing 3% hydrogen peroxide and a low-abrasive polish formulated exclusively for the Plus + White system.
They use wall-mounted units that OSS installed (but that now are Vienna's property) to clean according to a standard sequence: prerinse, foam, scrub by hand, rinse, sanitize.
Plus+White, a prerinse, gel and polish used to brighten teeth and remove coffee and tobacco stains without abrasives, rang up more than $10 million in sales in the first four months following its introduction and should post volume of from $25 million to $30 million in its first year.
