How often should I change my Deveiner blades?
• That depends on your product and the type of water you use. Rock shrimp veins, for example, typically harbor a lot of sand which dulls the Deveiner blades very quickly. So processors running rock shrimp must change blades every 3-4 hours. However, processors running a softer product like white gulf shrimp could devein for 4-5 days before replacing their blades. Also, processors who use well water, which is high in iron content, will have to replace blades sooner than those who use municipal water. • How can I control yield loss in my Deveiner? • Basically, two problems cause Deveiner yield loss: inconsistent vein removal and incomplete back-cutting. You can control these problems by monitoring 1) the water level and 2) the Deveiner blades. 1) The water level is the most significant factor in deveiner yield loss. Adjust your water level according to the symptoms: increase the water level to eliminate “bare backs” and reduce the level for better vein removal. 2) Dull or damaged blades
