GEA YieldJector

Working principle 
A belt moves the products a fixed distance (112 mm) under the needle head. It then stops and the injection cycles starts. When the
needle head moves down, the stripper plate touches the top of the products, a brine supply valve opens and needles start to inject. If a needle touches bone, injection stops and the needle retracts into the head. A centrifugal pump feeds the needle head with brine from the brine tank. Return brine is filtered in the brine tank and then recycled.

• Belt moves products to fixed distance (112 mm) under needle head
• Needle moves down, stripper plates touches top of product
• Brine supply valves opens, needles starts to inject
• If needle touches bone, injection stops and needle retracts into needle head
• Centrifugal pump feeds the needle head with brine, return brine is filtered in tank and then recycled 

Performance
Brine distribution is accurately controlled in the GEA YieldJector using advanced needle heads with individual needles that are  automatically adjusted by air pressure. When a needle is obstructed by a bone, it retracts and stops injecting, avoiding brine pockets and bone damage. Injection is executed in two identical injection cycles with a belt movement of 112 mm between them. Positioned
in a close pattern, the 2 mm diameter needles ensure optimal brine distribution.

• Injection levels up to 80 %
• Capacity up to 15.000 kg/h
• High accuracy thanks to individual needle control
• Low cost of ownership thanks to ease of operation, maintenance and cleaning
• Strong and reliable 

Output quality
To get the right injection level, two patterns and two injection modes are provided. For low injection levels (positive down injection), all needles are opened before they make contact with meat and they inject during the down stroke only. For high injection levels (positive down and up injection), injection takes place during both the down and up strokes is with all needles open. 

• Close needle pattern for maximum accuracy
