I don't know if it helps or not... But here are my process steps, before after and during processing. For me the key is keeping it clean. I'm probably working at a larger scale but the concepts are the same. It takes the same amount of labor to setup and cleanup to do 50 birds as it does to do 300, so more is better.
I take my birds off feed at noon the day before processing, crate them and remove water at 4:00 PM the day before processing. I don't stack crates to avoid the obvious.
1. Everything from kill cones to chill tank are thoroughly cleaned and disinfected.
2. Kill cones & stand and blood catcher all sprayed with olive oil.
3. Fresh tub with fresh water on first station, bowels with ice water on the evisceration station.
4. About a quarter cup of dish soap goes into the scalder when filled with fresh water, covered and started to heat up. I use a featherman pro setup.
5. Two pounds of ice per bird, plus 20 pounds of ice go into chill tank with water once the scalder is up to temp.
6. We kill 4 birds at a time and let them bleed out, then again 4 at a time go to the scalder.
7. Then into the plucker, which is rinsed out throughout the plucking process and after.
8. Out of the plucker, Feet, Head and Oil Gland are removed, feet saved in separate bucket with ice water. The birds are rinsed and placed in the first tub.
9. I retrieve the birds from the first station eviscerate one at a time awful goes into a bucket under my table, Heart, Liver and gizzard go into bowels with ice water. Bird goes into a laundry tub with fresh water, station and knives rinsed with fresh water. Four birds go to left sink then four birds to right, one is always filling with fresh water while the other soaking. I use float valves which rinse the tub and birds during draining.
10. Five or so minutes after the last bird goes into the tub, the tub is drained each bird is rinsed and QA checked and submerged into the chill tank after a final rinse.
11. Once the birds reach an internal temp (should be 40 minutes or less) of 40 degrees, they are transported into the house in clean lugs. There they are either cutup and vacuum packed or shrink wrapped whole. Livers, hearts and feet are cleaned and vacuum packed. Gizzards are covered and go in the fridge overnight. All of the packages (I generally leave one out in the fridge for tomorrow's dinner), go into an upright freezer that has a battery powered fan in it for quick freezing.
12. All biodegradable stuff goes to compost pile.
13. Everything from kill cones through chill tank is drained, washed and disinfected. Scalder and chill tank are covered.
