Trial Number 3

Trial Purpose:

To evaluate potential alternatives for dairy equipment using manual cleaning.

Date Run:


Experiment Procedure:

Five products were selected based on past testing results matching client supplied information. All products were used at full strength 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.

Success Rating:

Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.


Four of the five removed over 90% of the sweet milk from the stainless steel coupons using manual wiping. The top performers will be tested on the equipment at the facility.
