AI Technical Summary
When mixing dry feed for insect farming, existing mixers often result in large particles being thrown to the upper layer and small particles flowing to the lower layer, leading to uneven mixing and affecting the final mixing effect.
A mixing device for insect farming was designed. By setting baffles, guide plates and screens inside the mixer, and using a vibrating motor and mixing mechanism, it is ensured that fine particles enter one area first and larger particles enter another area later. The mixture is then discharged through the discharge pipe to achieve uniform particle size.
It improves the uniformity of dry material mixing, reduces the stratification of dry material after mixing, and ensures the uniformity of particle size ratio in the final discharged material.
