Trial Purpose:
To identify possible cleaning products for dairy equipment cleaning
Date Run:
04/03/2009Experiment Procedure:
Six products were selected from the lab's on-line database, www.cleanersolutions.org, based on past testing results matching client supplied information. Each of these products were diluted to 5% using DI water in 400 ml beakers and heated to 120 F on a hot plate.
Peweighed stainless coupons were coated with the whole sweet milk contaminant using a squeeze bulb. The contaminant covered coupons were put in an oven at 130F and dried for 15 minutes. Once dry, the coupons were weighed a second time to determine the amount of milk applied.
Three coupons were immersed into each solution and cleaned for 5 minutes using stir-bar agitation. Rinsing was performed for 15 seconds using tap water heated to 120 F and followed by 60 seconds of air blow off with dry compressed air at room temperature. Final weights were recorded and efficiencies were calculated for each coupon cleaned.
