GEA introduces MultiJector 500 for flexible meat injection processing lines
Machine designed to improve injection control, cleaning efficiency and production continuity
GERMANY – GEA has introduced the MultiJector 500, a brine injection system designed for small- to mid-capacity processing lines used in meat, poultry, and fish operations.
The equipment joins the company’s MultiJector range and replaces earlier 450 mm-wide models previously used in similar applications.
It is intended for processors producing items such as ham, deli meats, bacon, poultry and fish, with a focus on maintaining product consistency, improving uptime and reducing sanitation workload.
Needle control and injection design
The system uses application-specific needle setups, where processors can select either 2 mm or 4 mm OptiFlex needles depending on the product and process requirements.
Needle diameter and spacing determine how brine is distributed inside the product, which influences curing uniformity and can affect yield stability and product quality consistency.
The revised drive system is designed to limit mechanical impact on products during injection while supporting more stable brine retention, which helps reduce drip loss during later processing stages.
Cleaning and filtration systems
The MultiJector 500 includes a ScreenFilter option within GEA’s Modular Injector Filter system, which is intended to maintain brine cleanliness, particularly in poultry applications where contamination risk is higher.
A tool-free belt removal mechanism allows cleaning cycles to be completed in under ten minutes, reducing the need for extended downtime and lowering water and brine consumption during sanitation.
Operational efficiency was a key design factor, as processors are increasingly dealing with shorter production runs and frequent recipe changes that place pressure on line availability and labour use.
GEA indicated that maintaining uninterrupted operation over an eight-hour shift could save between one and two hours of production time in some setups by reducing filter cleaning and needle maintenance interruptions.
The MultiJector 500 is positioned within GEA’s broader marination systems, which can combine defrosting, brine preparation, injection, tenderising and tumbling stages into configurable processing lines based on production capacity and product mix.
