Jiangsu Liangyou Zhengda Co., Ltd is specialized in manufacturing feed machinery and engineering, we can offer customer complete machine solutions for livestock feed(pig and others) , poultry feed(chicken, duck, goose and others), ruminant feed(cattle, sheep and others), normal aqua feed(four major Chinese carps), special aqua feed(shrimp, crab and others), extruding aqua feed(floating and sinking fish feed, shrimp and others), premix feed(including various additives), pet food(cat food, dog food and others), we can meet customers' kinds of needs.
Now we take the case of 60000T per year small pig feed and 600000T per year fattening pig feed production line, make introduction based on process diagram and each process as follows:
Raw material:
maize, (extruded maize, extruded soybean , extruded soybean meal--used for baby pig), fish meal, Limestone, whey powder , fat, bone and meat meal, salt, premix and etc.,
Flow process introduction
Due to the large production capacity of this project, and the feed is mainly used for own farm, labor-saving automation equipment is adopted as far as possible. Main raw materials are stored in silo, the rest of the raw materials are fed manually by forklift through the intake in warehouse, the production process is controlled by central centralized control room, and the finished products use both automatic packaging line and bulk line. Among them, the production lines of high-grade baby pig feed and fattening pig feed are built in the same workshop. Except for the common raw material silos and bulk FP silo, the other equipment and operations are completely independent.
9-6000T raw material silo are used for maize storage, it is bolt silo which model is ￠22m×20.16m, flat bottom basement with sweep auger, the total power of machine is 930kW
36-200T bulk silos are used for finished pellets storage, bolt silo with model ￠6.4m×8.96m, supported by large steel structure platform, all steel cone discharging with truck loading on the bottom.
The total area of RM silo and bulk silo is 115×85×24.5m, the silo area is separated from production area with reasonable layout.
High grade baby pig feed production has following characteristics: fine grinded particles(the hole diameter of screen should be 1-2mm), high requirement for curing (first pellet mill use double conditioner and reteiner), low conditioning temperature(adopt second pelletize in low temperature to reduce inactivation of heat sensitive materials), small diameter for finished pellet (the diameter around 2-3mm). The 60000T per year small pig feed production line has two grinding line, one batching and mixing only line, one pelleting only line , second mixing line, second double pelletizing line and an automatic bagging line. The total power will be 930KW.
Normal fattening pig feed production has following characteristics: moderate grinded particles(the hole diameter of screen should be 2-4mm), moderate requirement for curing (pellet mill use double conditioner), large diameter for finished pellet (the diameter around 2.5-4mm). The 600000T per year fattening pig feed production line has four grinding line, two batching and mixing line, four pelleting line and four automatic bagging line and bulk line. The total power will be 2870KW.
The workshop construction area(two line is built is same workshop) is about 30×27.5×31.5m with 8T boiler(for whole line). The whole line is characterized by compact design and reasonable structure, and the satisfaction of environment protection requirements, meanwhile it can be directed to customers design.
