Y-LW large-scale continuous spray fluidized bed granulation, pill making, drying production line

Adopting the fourth and fifth generation technology of large-scale continuous spray fluidized bed granulation, pelletizing and drying (including top spraying internal heating process, top spraying internal heating process with channel, and process package technology): “large-scale continuous energy-saving fluidized bed flexible granulation coating and drying complete set of technology”, the production line’s stability and safety, product quality, and energy-saving effect have been raised to the next high level. Since 2012, the top spraying process has become the labeling process of Rifa, and the fifth generation technology has blossomed in many ways.

The fourth generation of top spray internal heating technology in order to gradually upgrade, there have been a number of sets, tons of large-scale projects and a number of small and medium-sized project applications, large-scale continuous energy-saving fluidized bed flexible granulation coating and drying technology in 2013 through the appraisal of scientific and technological achievements, to reach the international leading level, for the typical results of independent research and development technology.

Taking fermentation liquid as an example, the engineer’s first-generation technology is the two-step method of spraying and then granulating; the second-generation technology is the side-spraying with internal heating, adopting the method of mechanical energy; the third-generation technology is the side-spraying with internal heating, not adopting the method of mechanical energy. Because the composition of the liquid may be very complex, containing sugar, various amino acids, inorganic salts, etc., when using these three generations of traditional technology to produce feed additives, there is a high temperature of the layer of material, dust in the system, the atomization of the energy requirements of the large, seriously uneven growth of the particles, the finished product is not easy to adjust the density of easily clogged spray gun can not be adapted to the atomization of the material of the liquid of the higher content of dry matter, resulting in the production line high operating costs and operational stability. Poor operational stability (short continuous time, fire, explosion), poor product quality, environmental pollution is relatively large defects.

This large-scale continuous spray fluidized bed production line combines the principle of fluidization with the principle of spraying, through the study of fluidized granulation coating microscopic particle action mechanism, fluidized granulation coating equipment principle research, material properties and performance research, the overall process of the production line research as well as technical research on the structure of the granulation bed, to achieve the new combination of complete sets of technology, the specific innovations are as follows.

(1) Design and development of the unqualified small and medium-sized particles to reach the discharge port can automatically reverse the movement and avoid away from the discharge port of the technology, fluidized bed does not produce unqualified large particles of technology.
(2) On the same fluidized bed granulating and coating machine, the finished product pile density is adjustable;
(3) designed and developed on-line cleaning technology for air inlet chamber of fluidized bed granulator, energy saving and emission reduction, clean production and other technologies;.
(4)The developed fluidized bed granulator adopts modular structure and realizes product diversification and serialization through upgrading.
(5) Product quality and yield, energy efficiency, stability and safety and other comprehensive technical indicators than the existing technology to improve a lot, to achieve from a variety of liquid raw materials to solid particles preparation of high-quality spray fluidized bed preparation technology of industrialized production.
