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 Single SZLH420 poultry feed production line, make introduction based on process diagram and each process as follows:

Raw Materials:

The common raw materials are mainly consist of corn, wheat, barely, oats, sorghum, soyabean, soyabean meal, fish meal, amino acids, miscellaneous meal, whey powder, oil, meat and bone meal, grains, feed additives etc. more than ten varieties of raw materials.

Flow process introduction:

The features of poultry & livestock feed is that the crush fineness is moderate (the hole diameter of screen is 2-4mm), the curing degree is moderate (the pellet mill use double-layer conditioner), the diameter size of finish pellets is large (about 2.5-4mm). The capacity for SZLH420 livestock and poultry feed is designed to be 10tph, using one grinding process, double scale automatic dosing process, one mixing process, one pelleting process and one bagging process. The total power of this line is about 390kw, the working land size is about 16*11*26m, and matching 1ton boiler. The whole line has compact design, reasonable structure and meets the requirement of environmental protection. It can be customized according to customer"s requirements.

Technological characteristics and introductions:

RM receiving and cleaning process:

In this process, the clean system for granule receiving and cleaning is separated from powder receiving and cleaning, dust collection are individual which is with the better effects.

cleaner: granule precleaner SCY80, output 20-30t/h, powder cleaner SQLZ60×50×100, output 10-15t/h.

Grinding process: 

1set of hammer mill is adopt in this process, 3 grindings bins are equipped to cross crush different raw material; The impurities could be removed from raw material by magnetic separation equipment before grinding bins to ensure the safe running of hammer mill. 

Grinding equipment: hammer mill SFSP668×800, 110KW, output 10-15t/h

Batching and mixing process:

in this process, we use 15pcs batching bins, two batching scale work at same time which is controlled by FDSP developed independently batching program, achieve accurate quick and slow feeding, quick batching and with high accuracy.

Weighing equipment: batching scale PCS10 /PCS05, weighing accuracy: dynamic≤3‰, static≤1‰.

Granulation process: 

One set double conditioner pellet mill is used in this process. Two pellet bins are equipped for the pellet mill. After granulation, the pellets enter into the cooler, bucket elevator and then go to screening by rotary screener. The finished products go to the packing bins, others go back to the pellet mill other received by bags.

Granulation equipment: :SZLH420, 110KW,output 10-12T/H.

Packing process: 

there are 2 FP bins in this process, 1 of them only used for pellet finished products storage, the other can store both mesh feed and pellet feed. There is special anti-grading device for mesh feed bins. The pellet feed and mesh feed will be weighed and packed finally by packing scale.

Packing equipment: belt packing scale(both for mesh feed and pellet feed), weighing rage 20-50kg/bag, 6-8bags /min. 

Auxiliary process: 

dust collection system can improve the work condition, the oil adding system is usually seen in the mixer adding system which can improve the feed palatability.
