Multiple adjustment features that enables processing varying bird flocks. Within the same machine set-up our machines can effectively process bird sizes that vary with +/- 350 grams (12 oz). Adjustments can be performed during production to optimise uptime. Correct adjustment ensures high yield and minimises faecal contamination. Vent Cutter The Vent Cutter removes the vent from the chicken with a circular cut around the vent opening. During cutting, the birds are firmly positioned using specially designed hip huggers. The result is a highly accurate cutting performance. To ensure correct adjustment, the machine is equipped with three hand-operated hydraulic jacks that allow precise adjustment of the main shaft - even during production.
