Trial Number 1

Trial Purpose:

To continue testing alternative cleaners for dairy processing equipment

Date Run:

04/10/2009

Experiment Procedure:

Five products were selected based on past testing results matching client supplied information. Three products were used at full strength and two 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 sprayed with cleaning products and then cleaned with manual wiping. Rinsing was not needed and coupons were air dried. Final weights were recorded and efficiencies were calculated for each coupon cleaned.
