Premix feed is the brief name of Additive premixed feed. It is proportioned with one kind or various kinds of micro element(include all kinds of micro mineral element, vitamins, Synthetic amino acid, some medicine and some other additive, etc.) with diluent or isotopic carrier, and then evenly mixed to be made into intermediate type feed products.Premix feed is the important part of complete formula feed.
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 SFYH1000 automatic batching premix feed set, make introduction based on process diagram and each process as follows:
Raw material:
The raw materials are mainly diluent or isotopic carrier, adding kinds vitamins, minerals, and medicines. The feature of premix raw material is small amount, numerous varieties and mainly powder type.
Brief introduction for flow process
SYHF1000 automatic premix is designed by 1t/batch (about 6tph), which the carrier and the micro element are separated to be weighed automatically by computer. One unit of single shaft mixer, one unit of automatic bagging machine especially for premix feed. The total power is about 63kw. The construction area of the production workshop is about: 12*11*33m. The whole line is with compact design, reasonable structure, suitable to environmental requirement, which can be customized specially by customers demands.
Technological process chart:
RM receiving and cleaning process -- batching and mixing process-- packing process-- Auxiliary process
Technological characteristics and introductions:
Combine the premix feed feature of easy to cross contamination and grading, in this design, the carrier will go straight from bin to the end packing after lifted, the material flow by its gravity which can prevent cross contamination and grading caused by second lift and transportation.
RM receiving and cleaning process:
remove the impurities from raw material to make sure the quality of product and continuous machining safety of the processing equipment.
Cleaning equipment: Powder precleaner,SQLZ60X50X100，5.5KW, the designed output 10-15T/H
Batching and mixing process:
This process adopts two batching scales, four carrier bins weigh separately, and eight small bins weigh separately, which the micro elements are added manually and equipped with checking scale. The material are mixed in the mixer after batching and then directly into the finished product bins.
Weighing equipment: pcs-05 / ps-02 of batching scale, the batching accuracy: dynamic≤3‰, static≤1‰.
Mixing equipment: mixer SDHJ. 2, 18.5kw, 1000kg/P, designed output 6T/H(premix). homogeneity CV≤5%.
Packing process:
The final premix after mixing will fall into FP bins directly, then enter into the packing scale buffer hopper through airclosed feeder to be weighed, finally being insert the label and sewed by special machine.
packing equipment: packing scale special for premix, range 20-50kg/bag, 3-5bag/min
Auxiliary process:
dust collection system, the dust collection on intake and packing position can improve the work condition for worker.
The process can be optimized according to different customer needs:
1. here the micro elements are added by manual, customer could choose optional automatic micro elements adding system
2. The quantity of carrier bins and small material 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 dust collection system on packing position can improve working position, customers can consider whether it is needed by himself;
