Factory producing Cheddar, material to clean cheese vats, "cheese spining machine" and cheese

press.

B Cur rent Situation

Cleaning from a C.I.P. using soda at a concentration of 1 % (alkalinity) with Lowfix (Diversey-Lever)

at 0,2-0,3 %.

The acid cleaning frequency is once a day.

obtain a solution which sequestering capacities are the same than with the DEPTAL ACT method.

The result is satisfactory, after 3 weeks use, very few foam

The acid cleaning frequency is once a week.

Under no circumstances concentrated soda can be added.
