RE: Medical Device and lotion manufacturer
Tammy --- I used to be a manufacturing engineer in a plant that made skin
lotions. Our lotions contained petrolatum as well as glycerin which helps
dissolve the petrolatum. My cleaning recommendations for your client would
1. Do material addition sequences & batch scheduling to minimize cleaning.
2. Use a dedicated petrolatum tank and piping (we didn't do this)
3. Handle the petrolatum as hot as possible (I think we stored it at 160 F)
to minimize its viscosity & hang-up on tanks & piping.
4. For cleaning, 180 F hot water was all we ever needed. A good
tank-cleaning sprinkler ball is important. If cleaning piping is a problem,
look into pipe cleaning pigs.
I'd be happy to talk to you our your client on the phone.
