Good afternoon all,
I work for a pet food manufacturer using extruding as our primary method of production. We currently tear down and clean between product changeovers and clean everything weekly. The question has been raised if it would be possible to run products back to back and just "purge" the first 50-100 lbs of product. Several in our company have stated that this is what everyone else is doing. This has not been my experience but my experience in the food industry is limited to work at two food manufacturers.
This process is assuming that the first portion of the material is being used to remove the lingering residues of the product before it. This wouldn't change the weekly cleaning but would significantly improve up-time in production. We certainly don't want to create a risk by using a method like this and we just achieved SQF lvl 2. I certainly don't want to jeopardize that either.
- Does anyone have any experience with this type of method?
- If so, any tips on what to avoid?
- What about like and unalike product formulas?
- Are there materials that could be used for the purging process to reduce the amount of formula being tossed at changeover?
We're producing products that are both strait up treats and some that would be considered supplements. Some treats have meat in them and are exposed to a thermal treatment. Many of the supplements are cold formed and have strict separation between the two processes.
Any guidance is greatly appreciated. Thank you so much.
