How should needle count be matched with meat-piece dimensions on a commercial brine injector?

Match needle spacing, needle count, and stroke with meat dimensions, then test injection uniformity across different positions. A sample demonstration is useful, but continuous production data is needed to verify repeatability and practical capacity. The supplier should identify any capacity limit caused by product temperature, moisture, particle size, or other material properties. For critical parameters, require signed records from both parties and retain the original data with the order documents. For equipment with change parts, list every required component and its adjustment range before placing the purchase order.
