Large scale fish feed production equipment is divided into two types based on the heating method of the puffing machine: electric type and steam type, with a production capacity ranging from 100kg/h to 5000kg/h. By adjusting machine parameters and the ratio of raw materials, various types of feed pellets suitable for various fish species can be produced, including floating fish feed, suspended fish feed, and submerged fish feed. Replace the mold to produce fish feed of different specifications from 0.5mm to 50mm. The raw materials of the production line designed by Jinan Linyang Machinery Co., Ltd. are mechanically extruded once to form uniform particles. Production is completed in one go by mixing raw materials, shaping particles, drying, spraying, cooling, and packaging.
