GEA brine injector

The GEA MultiJector 500 brine injection system is designed for small- to mid-capacity marination lines handling ham and deli meats, bacon, poultry and fish. The machine combines configurable needle set-ups with a modular filtration concept intended to improve product consistency, line availability and sanitation efficiency.

Succeeding earlier systems in the 450 mm width category, the brine injector is aimed at processors looking to increase throughput, broaden their product range or update equipment to improve brine retention and meet stricter hygiene, safety and sustainability requirements.

At the centre of the system is an application-specific needle configuration. Processors are guided towards 2 or 4 mm OptiFlex needles, depending on the product and process objective. In injector technology, needle diameter and needle density determine the injection pattern — the distribution of injection points across the product surface. A denser pattern can improve brine dispersion, which is particularly important where uneven curing may lead to microbiological risks, yield loss or inconsistent product quality. The system is also designed for relatively fast conversion between applications, allowing processors to switch product categories without extended changeover times.

The MultiJector 500 and 700 are at the heart of the line in larger GEA marination lines covering defrosting, brine preparation, injection, shaking/tenderising and tumbling. This allows processors to configure complete lines around specific capacity targets and product mixes rather than treating injections as a standalone process step.

GEA will present the MultiJector 500 at interpack 2026 in Germany from 7–13 May. (Hall 6, Booth C27.)
