Opener M4.0 Pro

Clean incisions with uptime, hygiene, and precision built in

The Opener M4.0 Pro is built to deliver clean, accurate abdominal incisions at full line speed—day in, day out. At the core is Meyn’s patented swivel scissor mechanism, which rotates the blade in sync with the bird’s natural anatomy. This controlled motion reduces the risk of internal organ damage and ensures consistent cuts across a wide range of flock sizes. Combined with a 240° curved layout that increases handling time per bird, and automatic rinsing after every cycle, the Opener supports high-capacity, hygienic performance without unnecessary complexity.

Modular by Nature, Synchronized by Design

As part of the M4.0 Pro series, this machine shares the platform’s modular design, integrated utilities, and safety features—making it easy to maintain and fully aligned with the rest of the line. For the Opener, this means quick access to the blade and guidance system for inspection or cleaning. The modular shaft and open frame allow for safe, efficient service, while the standardized design helps maintain consistent cutting performance without downtime.
 

Tailored to Your Business Needs

The Opener handles a wide range of bird weights and flock profiles within a single setting. A free-positioning system ensures proper alignment, while the guided blade mechanism maintains cut accuracy regardless of carcass variation. Optional features like spray-assisted cleaning and mid-shift rinsing help maintain hygiene during production without interrupting throughput. Whether you're managing shift-to-shift variation or scaling up production, the Opener is built to keep pace—reliably and efficiently.
