Poultry, ruminate feed granulation process: double conditioner is used in this process special for livestock& poultry and ruminate feed production. Two pellet bins are equipped for every pellet mill which will be easy to change the formula. After granulation, the pellets enter into the cooler, crumbler, bucket elevator and then go to screening by rotary screener. The finished products go to the packing bins, and the screened powder go back to the pellet mill, oversized pellets return to the crumbler.
Granulation equipment(2sets): :SZLH420(110KW),output 10-12T/H/set. Cooling equipment(2sets):SKLN6,output 10-15T/H/set.
Livestock and poultry feed, ruminate feed packing process: there are 4 FPbins in this process, 2 of them only used for pellet finished products storage, other 2 bins 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. We can also design automatic stacking system for customer's need.
Pulverizing process: we adopt 2 pulverizer in this process to make second grinding for extruding line and shrimp crab feed line. Pneumatic type discharging, cylone, pulse filter are used, the particle size after grinding can be adjust according to customers' needs.
Pulverizing equipment(2sets): SWFL130,160+15+2.2KW. Output 3-6t/h/set

Shrimp and crab feed granulation process: This process adopts one belt driven shrimp specialized pellet mill, which is equipped with double shaft differential conditioner + retainer + jacket conditioner, effectively ensuring the pre-curing of granulation, two pellet bins are equipped above the pellet mill. The finished product after granulation is put into the stabilizer for post-curing treatment to improve the stability of feed in water. In order to solve the problem that the moisture of large crab feed is easy to exceed the standard level, this project specially added the drying process, the pellets from the stabilizer first enter the vertical dryer to remove the excess moisture, then enter the cooler to be cooled, and finally lift into the rotary screener for screening, the finished products go into the packing bins
Pellet mill:. SZLH420X,55x2KW, output for shrimp feed 1.5-2.5/H. Stabilizer SWDB4,1.1+1.5KW, Vertical dryer SHGL4,1.1+1.5KW, Cooler SKLB4,1.1+1.5KW, volume 4m3 output 4-5T/H.
Packing process: rotary screener is added under the two FP bins which can reduce the powder among the pellets before packing scale. pellet packing scale is adopt.
Packing equipment: quick pellet packing scale, range 20-50kg/bag, 4-6bag/min
Shrimp and crab feed crumbling process: the purpose of this process is to produce seedling shrimp and crab feed, the large pellets will go to crumbler first then screened different size final products by double high plan sifter according to the different need of each stage of seedling shrimp and crab.
Auxiliary process: dust collection system, the dust collection on packing position can improve the work condition, the oil adding system is usually seen in the mixer adding system which can improve the feed palatability, molasses adding used for ruminate animal, it can use manual adding hopper, molasses adding system could adopt for 3% addition.

The process can be optimized according to different customer needs:
1. Single point dust collection mode is used in the plan which means pulse filter is equipped for every rotary distributor(mesh) and granule cleaner with good effect. Single point dust collection is kind of humanized design of our company, to provide a better working environment, but the cost increases, customers can consider whether it is needed in actual situation;
2. The quantity of bins can be adjusted to achieve the beast use ratio and effectively control the production cost based on factors such as customers' formula, characteristics of raw materials.
3. The crumbler after cooler is optional, especially when producing poultry feed and young poultry feed, the crumbler could break the large pellet into small pellets to improve production efficiency and reduce production cost.
4.the vertical dryer in shrimp and crab feed granulation process can be selected according to need, there is no need to consider it if no large crab pellet production.
