I work for a walnut company.We have a dry sanitation program in place that has given us good results in the past years.Most of the equipment are stainless steel along with plastic sorting belts and elevator buckets.
We accumulate a lot of soil buildup (dust and oil) in the equipments from the walnuts and it meal. Our basic protocol is to blow off most of the the dust with air pressure gun, vacuum it, clean manually with dry rags and then spray surface sanitizer (Alpet D2) in the end. The amount of alpet D2 sprayed largely determines our ATP and microbiological results as it is doing dual job of cleaning and sanitizing.
My company wants to introduce some kind of cleaning agent before we sanitize with alpet D2. They are looking for options to reduce our sanitation cost as we use very large amount of Alpet D2 everyday and depend on it for good results.
One of our chemical supplier suggested using 3% hydrogen peroxide solution. They are suggesting us to use wet rags instead of dry rags. However, I'm concerned that it will be introducing moisture in the plant and may damage our walnut product. I tried finding literature about it but only found about their use in wet sanitation program.
Sorting belts are my biggest concern. The lower part of the belt is porous and has lot of soil formed under it. They are not taken off the line to clean everyday and are very firmly attached to the stainless steel frame.It is not possible to take off the belt every time we clean. We take them off monthly depending on need/ work load. I am worried using water based product will absorb the wetness and may not dry out properly affecting products eventually. Even stainless steel may have residual wetness after cleaning since water does not evaropate off.
Does anyone have similar experience in the dry plant? Any suggestions on sanitation methods, cleaning agents or use of water based products like hygrogen peroxide solution will be highly appreciated.
Thank you .
