Trial Purpose:
To continue evaluating possible cleaning alternatives for dairy equipment.
Date Run:
04/16/2009Experiment Procedure:
Three additional products were selected based on past testing results matching client supplied information. Three 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.

Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
Two of the products removed over 85% of the whole sweet milk from the stainless steel coupons using manual cleaning.
