Improved airflow distribution on board (screen) of the recommendations: Currently, most fluid bed dryer using air distribution plate in the form of a single, multi-use vertical perforated plate or mat-shaped stencil material in the flow of the process is prone to not fluidized all problems or dead ends. Not ensure uniformity of the drug particles, while a single aperture in the form of different drugs can not meet the requirements of the production process. On the other hand, in order to reduce the leakage of material loss products, now widely used in multi-layer network structure, air distribution plate and a lot more use of fluidized bed bolted, demolition convenient, easy to wash and clean a removable produce residues cause cross-contamination issue. Suggestion: use of computer dynamic model, heat and mass transfer model, the design of air distribution plate for pitch dryer, aperture opening rate and other parameters into account aerodynamics, thermodynamics simulation and verification, in order to meet the different materials production process. On installation, the connection standard. In order to ensure quick and thorough and complete cleaning. Changzhou Heng Cheng dry granulation Equipment Co., Ltd. is engaged in drying equipment and granulating machinery research, development and manufacture of professional manufacturers, is currently producing more varieties drying equipment specifications than the entire enterprise. One of boiling dry powder devices insecurity: factors dust explosion dust explosion is defined as the suspended dust particles in the air with oxygen in the air full contact, instantaneous oxidation reaction under certain conditions, the reaction of the release sodium perchlorate dryer large amount of heat, resulting in high-temperature, high-pressure phenomenon. In general, the combustible solid in air is released out of the combustion energy, and a large amount of gas, while both fast and slow release of energy in the burning velocity and the size of solids (dust) in the exposed area of ??the relevant air. Therefore, for the same kind of solid powder material, the smaller the drug particle size Driers, larger specific surface area, the faster the diffusion combustion. If the size is very fine solids, as well as antibiotics can levitate dryer, so that if there is an ignition source ignited, can in a very short period of time release large amounts of energy, the energy dissipation was too late to go to the surrounding environment, resulting in The space inside the gas is heated and absolute expansion, while a large amount of powder combustion gases on the other hand, will form a local high pressure system, as well as an explosion and spread.
