1、Y-LW Large continuous spray fluidized bed granulation pellet drying production line
   Large scale continuous spray fluidized bed granulation, pelletizing and drying fourth, fifth generation technology ( top spray  heating process, channel top injection internal heating technology, process package technology): "large continuous energy-saving fluidized bed flexible granulation drying technology package", the production line's stability, safety, product quality, energy saving effect is raised again. Since 2012, the top spraying process has become the RIFA label process. The fifth generation technology has blossomed and fruited in many aspects, and the design accuracy can now be controlled at 5%.

The fourth generation top spray internal heating technology has been gradually upgraded, and has been applied in several sets of large-scale, 10000 ton projects and several small and medium-sized projects. The complete set of large-scale continuous energy-saving fluidized bed flexible granulation coating drying technology passed the appraisal of scientific and technological achievements in 2013, reached the international leading level, and is a typical achievement of independent research and development technology.

Taking fermentation broth as an example, the first generation technology is the two step after spraying and granulation. The second generation technology is heating in the side jet belt, using the method of mechanical energy; The third generation technology is heating in the side jet belt without mechanical energy. Because the composition of feed liquid may be very complex, including sugar, various amino acids, inorganic salts, etc., when these three generations of traditional technical methods are used to produce feed additives, there are high feed layer temperature, large dust in the system, large atomization energy requirements, serious uneven particle growth, difficult adjustment of finished product density, easy blockage of spray gun, and unable to adapt to the atomization production of feed liquid with high dry matter content, It causes the defects of high operation cost, poor operation stability (short continuous time, fire and explosion), poor product quality and large environmental pollution of the production line.

The large continuous spray fluidized bed production line combines fluidization principle with spray principle. Through the research of the mechanism of micro particle action in fluidized pellet coating, the research of the principle of fluidized pellet coating equipment, the research of material characteristics and service performance, the whole process research of the production line and the technical research of the granulator bed structure, the new combination technology is realized. The following are the specific innovations.

(1) The technology that unqualified small and medium-sized particles can automatically move in reverse and avoid leaving the outlet when they reach the outlet is designed and developed, and the technology that unqualified large particles are not produced in the fluidized bed;

(2) On the same fluidized bed granulation and coating machine, the bulk density of finished products is adjustable;

(3) The on-line cleaning technology of air inlet chamber of fluidized bed granulator, energy conservation and emission reduction, cleaner production and other technologies are designed and developed;

(4) The developed fluidized bed granulator adopts modular structure and realizes product diversification and serialization through upgrading;

(5) the comprehensive technical indexes such as product quality and yield, energy efficiency, stability and safety have been improved more than the existing technologies. The industrialized production of high quality spray fluidized bed preparation technology from various liquid raw materials to solid pellets has been realized.

This technology is more suitable for making, crystallizing and granulation, such as amino acid sulfate, hydrochloride and chloride salt, by one-step spray drying such as fermented liquid and emulsion. Widely used in biological fermentation; Additives, pharmaceuticals; Pesticide and chemical industry; Fertilizer and environmental protection; Food, fruits and vegetables, health products; Super sticky material;  Feed; Metallurgy, building materials and other industries, with the further improvement of this technology and the in-depth development of the market, its application field and scale will continue to expand.
 

2、Y-WQ One step micro pellet continuous spray fluidized bed drying production line

    (1) Background technology.

Many of the original preparations are powdered and crystalline products of the pulverizer, which have adverse factors such as electrostatic adsorption, slow dissolution rate, easy heating and degradation, flying dust and low bulk density. The finished products are expected to achieve the effects of good fluidity, fast dissolution, low heating, no dust and high bulk density. It is concluded that the particles that can meet this requirement are 50-80 mesh Micro pill preparation with a large number of micro pores and basically no dust. On the basis of basic product Y-LW liquid pellet continuous spray fluidized bed, the production line can be developed by optimizing the principle and parameters, combining patent application number and proprietary technology. It is also suitable for production of viscous materials and crystalline materials which are not available for WQ pellets production line.

(2) continuous spray fluidized bed pellets production process

Spray fluidized bed preparation method, for example, patent application No. 2012102562273, a spraying granulation method provides a technological possibility of directly obtaining nuclear pellets from liquid raw materials, but only using this technology is difficult to obtain perfect qualified pellets. Besides, ordinary particles produced by fluidized bed granulation process are not dense enough, or the roundness of particles is not enough, or evenness is not enough. Either the particle strength is not enough, or it can not be produced continuously, so it can not produce fine pellets that meet the requirements.

The method is to produce micro pellets by means of the spray fluidized bed coating and regular fluidization principle. Polishing method is adopted to polish and compress the surface of the product, and the production process of the pellets is made by the spray fluidized bed process and the optional polishing process. This process can directly obtain qualified micro pill products from liquid raw materials in one step, and can obtain pure quality products without adding auxiliary materials. The function of polishing method is to remove, compress and extend possible small thorns or high points on the surface of product particles, so as to make the micro pill meet the requirements of shape, particle size, surface finish, no dust and density.

7JXF Large energy-saving continuous fluidized bed dryer
   The large-scale energy-saving continuous fluidized bed drying production line obtains products without flying dust by continuously entering wet raw materials into fluidized beds (such as internal heated fluidized beds) for drying and cooling. An energy-saving fluidized bed system technology (in the process of patent application) is adopted. Compared with the ordinary continuous fluidized bed, it can reduce the exhaust volume of fluidized bed tail gas, make full use of the exhaust heat of fluidized bed exhaust, and the outlet materials have no dust flying, so as to improve the environmental protection of discharged tail gas, reduce the energy consumption of production line, no powder in outlet materials, improve the material yield, stable and safe operation High investment cost performance and low maintenance and operation costs.

The types include vibrating fluidized bed, horizontal multi chamber fluidized bed, internal heat exchange fluidized bed, high temperature fluidized bed, spout fluidized bed, etc.

The following processes can be realized: continuous drying and cooling of solid materials and high moisture absorption materials, continuous preparation and drying of powder raw materials, continuous drying, calcination and cooling of crystalline wet materials, and continuous preparation  to solid particles from liquid raw materials.

In the hot air drying process of wet materials, there are mainly constant speed drying stage and reduced speed drying stage. The high humidity exhaust in the constant speed section and the front section of the reduced speed section of the traditional fluidized bed and the low humidity exhaust in the rear section of the reduced speed section are usually mixed together, resulting in the difficulty of using the heat contained in the exhaust.

After the traditional fluidized bed drying exhaust gas is separated by the dust removal system, the solid particle size obtained is small, which does not meet the particle size range of the finished product. It is usually necessary to add liquid for re dissolution and recrystallization. Recrystallization will directly have recrystallization loss. At the same time, the added liquid needs repeated drying, resulting in increased overall energy consumption.

The available technical scheme of the JXF energy-saving continuous fluidized bed dryer is:

1. An energy-saving fluidized bed system comprises a fluidized bed main body, in which a constant speed section drying area and a speed reduction section drying area are arranged, and the fluidized bed main body is provided with an air inlet, a high humidity exhaust outlet and a low humidity exhaust outlet, which is characterized in that the air inlet corresponding to the constant speed section drying area is connected with the constant speed section air inlet system, The air inlet corresponding to the drying area of the deceleration section is correspondingly connected with the air inlet system of the deceleration section, the high humidity exhaust outlet is connected with the air outlet heat exchange system for heat exchange with the fresh air, the outlet of the heat exchange fresh air of the air outlet heat exchange system is connected with the air inlet system of the constant speed section or / and the air inlet system of the deceleration section, and the outlet of the low humidity exhaust outlet is connected with the air inlet system of the constant speed section or / and the air inlet system of the deceleration section.
