Flash dryer market hair-trigger, enterprise transformation and upgrading for development

　　Pharmaceutical Network Technical Article : Flash dryer, also known as a rotary dryer or rotary fast dryer, is a relatively fast-growing domestic drying model with wide application Flash dryer organic combination of fluidization, spin, spray, crushing and other technologies of optimization combination, with high thermal efficiency, short drying time, good energy saving and other advantages, suitable for paste, granular, filter cake and mud-like material drying At the same time, due to the fast drying speed, the material heat ingesting time is short, it is not easy to destroy the composition of dry materials, especially conducive to the drying of heat-sensitive materials At present, flash dryer enterprises according to different materials design edgy models, and formed a series of products, widely used in chemical, pharmaceutical, light industry, food, mining and other industries
Industry introduction, flash dryer structure is special, including the bottom of the drying chamber set the cone structure, the top of the drying chamber set a grading ring, the cone bottom hot air entrance to set the cooling jacket, stirring teeth on the set of scraper, etc , compared with other dryers have the following advantages
First, the drying strength is high It is reported that due to the design of flash dryer structure, the physical subject to centrifugal, shearing, collision, friction by the particle, a high dispersion state, the relative speed between the two phases of gas solidity is larger, strengthen the transmission of mass, heat transfer
Second, it is more suitable for thermal materials The high gas speed of the high temperature area at the bottom of the dryer is difficult for the material to come into direct contact with the hot surface, and the cooling jacket is attached, and the stirring teeth are equipped with a sharp plate, which all solve the material sticky wall, coking enthusiasm
Third, the process is more simplified Compared with the use of other types of dryers, with flash dryer drying paste paste, mud, filter cake and other materials can dry into a uniform powder products at once, eliminating the process of crushing, screening and so on
Fourth, it can effectively control the final water and fineness The regulation of feed and hot air temperature and the coordination of the graders can be fully controlled for final water and finished granularity, thus ensuring uniform wet content and fineness of the product
At present, the domestic flash dryer enterprises after a long period of development, has a certain technical experience, market share gradually increased With the rapid development of pharmaceutical, light industry, food and other industries, the market demand and requirements for flash dryers continue to expand, in this context, flash dryer enterprises between the fierce competition, and face greater pressure From the point of view of user demand, the industry believes that flash dryer enterprises need to improve drying efficiency, energy saving and other aspects to improve the market competitiveness of equipment
It is reported that there is a flash dryer manufacturer to optimize the structure of equipment, to create a high-speed rotary flash dryer, the equipment is by the hot air tangent into the bottom of the dryer, driven by the agitator to form a strong rotating wind field The paste material is entered into the dryer by the spiral feeder, under the strong action of the high-speed rotary mixer, the material is dispersed by the impact, friction and shear force, the block material is quickly crushed, and the hot air is in full contact, heated and dry The optimized structure of the rotary flash dryer drying faster, but also more energy-saving, can bring more benefits to the user
There are enterprises in the introduction, absorption of excellent technology on the basis of their own development of new flash drying equipment "We mainly improved the technical content of the equipment, optimized the design, and made the equipment more compact," the company said This new equipment has a wide range of applications, larger production capacity, energy saving, users in a device can make drying, crushing, screening one-time completion, reduce environmental pollution, the whole machine performance has a higher level Now, with a new wave of industrial revolution coming, intelligent manufacturing has become an important way for the transformation and development of manufacturing industries in various countries Based on the comprehensive transformation and upgrading of equipment manufacturing industry in the background of intelligent drying, is based on the drying equipment energy efficiency, environmental protection and product quality efficiency of the comprehensive consideration, a single extensive drying for a combination of intelligent drying, in line with the development requirements of resource-saving Flash dryer as a member of the drying equipment industry, if we can achieve intelligent upgrading, will significantly improve the drying process and the intelligent level of the product itself, thereby improving production efficiency, product technology and product quality, reduce resources and energy consumption, reduce production costs
