Spray drying equipment factory spray drying equipment, Su Cheng dried good quality certified

At present, there are various forms of industrial drying equipment, in order to facilitate the description, it is always drying equipment is divided into several categories, there are many classifications of drying equipment, summed up in the following categories: 1, according to the operating pressure classification according to the operating pressure It can be divided into two types of pressure-type and vacuum type. Atmospheric drying equipment can be used simultaneously in any one or several forms of heat transfer, and vacuum drying equipment is based on the characteristics of heat conduction and radiation heat transfer in the majority, most produce a batch-based, vacuum drying equipment mainly deal with heat-sensitive materials and have solvent recovery materials. 2, classified by mode of operation according to the drying device operation can be divided into two types of intermittent operation and continuous operation. It should be noted that some of the drying apparatus may have intermittent and continuous two modes of operation, while others only have a drying equipment. 3, according to the state of the dried material was classified common dry material state can be divided into block, strip, granular, paste, cake-like, fibrous, solution or slurry form, etc., in many cases, the original state of the material We decided to choose the shape of drying equipment. 4, according to the classification of heat transfer by heat drying equipment can be divided into convective heat drying equipment, drying equipment, heat conduction, radiation heat transfer and a variety of other heat transfer drying equipment. 5, according to the type of media classification with dry convective heat transfer can be divided into air, flue gas, superheated steam, inert gas is on drying medium. Conduction heat transfer can be divided into thermal oil, hot water, steam and so on. 6. The heat transfer process of drying equipment classified a relatively new classification method, the drying equipment is divided into two categories, the five categories. Two types of the drying process is adiabatic and non-adiabatic drying process. Adiabatic drying process can be divided into two categories: small particles out of the dryer, such as a spray dryer, flash dryer, fluidized bed dryer, a moving bed dryer and the rotary cylinder dryer; two is the bulk material dryers, such as box-type dryer tunnel drier, multi-layered and belt drying machines. Non-adiabatic drying process can be divided into three categories: vacuum drying, drying heat conduction, radiation, heat drying, which is characterized by non-adiabatic system. In recent years in the design and manufacture of spray device found blindly increase the volume trend drying tower, which will not only lose the advantages of spray drying time is short, but also increases the cost of plant and equipment occupies the area (or volume) for user disadvantage. When the hot air distribution and atomizer rational allocation volume drying tower should have a reasonable range, not a big difference. Big is not necessarily better. With the advancement of technology and the application of various strengthening measures, the drying tower is bound to get smaller. Hot air distributor is an important aspect, it does not mean all of them. So in a spray dryer design, selection according to the characteristics of various materials, integrated various parameters in order to obtain the best state of a system. Large centrifugal Spray Dryer Overview: Spray drying is a liquid process shaping and drying the industry's most widely used process. Ideal for producing powder, granular solid product from the solution, emulsions, suspensions and burnt like liquid feedstock. Therefore, when the particle size distribution of the finished product, residual moisture content, bulk density and particle shape must meet the precision standard, the spray drying is an ideal process. Large centrifugal spray principle: the air is filtered and heated air into the dryer at the top of the dispenser, the hot air was evenly into the drying room in the spiral. Passing through the top of the tower high-speed centrifugal atomizer (rotational) was sprayed into the extremely fine mist liquid beads. Through contact with the hot air, in a very short period of time can be dried into a finished product. Finished continuously from the bottom of the drying tower and cyclone exhaust gases vented by the fan.
