Our Seamer: Digitally Controlled Pressure, and Why It Matters

Seaming

9 min read

A can seamers job is to fold the can end (lid) around the can body in two precise mechanical operations, a process called double seaming, to tolerances as tight as plus or minus 0.05mm. Get it wrong and you get a leaking, unsellable can; get it inconsistently right and you get a fleet of cans with different seam quality sitting on the same pallet. ZANZ seamer replaces the manual springs, pneumatic force, and hand-adjusted tooling most machines rely on with a servo-driven, self-calibrating system accurate to 5 microns, because seaming is the one step in canning where close enough genuinely is not.

Rotary vs Inline Canning: Why Position Control Changes Everything

Architecture

7 min read

Rotary canning systems track the exact position of every can and trigger each fill, purge, and seam cycle in direct response to it, giving far more consistent cans and a smaller footprint than inline systems, where cans simply queue on a conveyor and get processed whenever an arm stops them. Rotary has long been the standard for large commercial lines for exactly this reason. It has just never been affordable at small-batch scale - until now.

Counter Pressure Canning: How It Works and Why We Built It Differently

Filling

8 min read

Counter pressure filling seals a can with CO2, pressurises it to match the beverage tank, then lets the beverage flow in against that back-pressure, controlling foam and minimising oxygen pickup far better than open (atmospheric) filling. It is the technique every large commercial canning line uses, from craft breweries scaling up to global players filling thousands of cans an hour. Until now, it has rarely been available to small-batch producers at an accessible price point. ZANZ SOLO builds counter pressure filling into a machine designed for a one- to twelve-person operation, with no canning specialist required.
