First, Brief
XF type boiling drier, also known as boiling fluid bed drier, technical design principles drier, the heated air is evenly distributed through the surface of the fluidized bed with wet material into the fluidized bed heat exchange is due to the heated air flow of the bottom of the bed into the fluidized bed drying chamber, while this exchange heat with the wet material, due to the effect of air flow, so that the formation of boiling fluidized wet material. The fluid bed drier using special design techniques to make the hot air into the fluidized bed, and the bed a certain angle of refraction, the dried material in the boiling of the can with the air motion, gradually move forward, so that the organic way material.
XF type boiling drier can be widely applied to dried pharmaceutical, chemical, food, light industry, granular, powder wet material, but also for dry desiccant medicine, granules, instant dairy products, biological products and other wet materials, with production large capacity, high thermal efficiency and advantages of continuous production.
XF type boiling drier to meet the different industries and different material properties requirements, drier heat and humidity can be adjusted between room temperature of 60 ℃ ~ 140 ℃. To this end drier type can be designed for insulation insulation type and non-adiabatic type categories, which fluidized bed type insulation insulation insulation effect. Bed beyond the flesh of their surface energy in a continuous state of maximum operating temperature, maximum surface temperature of the bed around them is not greater than the ambient temperature of 30 ℃.
To capture the application of different materials and finished collecting dust materials, drier systems are designed for receipt within a Tornado, Tornado and Gabe Bag bags three kinds of machine type, for users to choose, shirt and investment to improve the economy of the equipment.
As a heat source for all kinds of use of the environment, the heating medium were selected Office drier steam heating, steam heating + electric, gas, coal and heating oil heating of various types of type, so as to satisfy different user environments.
Using quality requirements apply to different industries, drier heated air neutralized, High efficient filtration, cleanliness of the heated air in contact with the material to reach 300,000 purification requirements, in line with the pharmaceutical industry GMP quality management standards and food production and quality of health Claim.
Second, the main technical parameters

The main technical parameters in Table 1

Note:

1) table specifications Model Notes to Table A for the Tornado, B for the bag-type, C is the whirlwind Gabe bag.
2) heating using steam as a heat transfer medium, steam Heat exchanger design pressure 0.2MPa ~ 0.8Mpa, the heating temperature is 60 ℃ ~ 140 ℃.
3) the use of adiabatic type drier, which type of formula, code-named the "D" indicates, slightly non-adiabatic type, user type in the election, in the same table sales note.
Third, the working principle and Features
1, the working principle
XF type boiling drier works will be ready to be put into the dry material feeder star form, by heating in air, High efficient filtration drugs Heat exchanger heat exchanger to heat the air by adjusting valve to adjust the bottom plate into the fluidized bed of evenly distributed on the surface in contact with the fluid bed feeder feeding wet materials, heat transfer and mass transfer heat exchange, due to the heated air that is sent Wind pressure force, wet material with hot air heat exchange in the heat transfer process so that the material presented boiling fluidized state, its boiling fluidized Height of 100mm-300mm. To this end the drier and title boiling bed, side vents fluidized bed using a specially designed, heated air into the fluidized bed and the bed plane presents a certain angle, whereby the hot gas stream in the production process in order to drive forward the material until the discharge port discharge. After separation, the lower portion of the finished set by the cyclone fan off receipts, in hot and humid air entrained dust material, carried by the baghouse installed to recover the catch, humid air through the bag filter is discharged by the induced draft fan. Complete process production process.
2 Features This product has the following characteristics:
1) This machine is suitable for pharmaceutical, chemical and food industries granular, powdery material dehumidification drying, apply medicine pills, granules and feed, food processing and other manufacturing operations applicable, has broad applicability.
2) drying principle The machine uses wind dynamics, enables the material to be dried in the heat transfer of heat exchange, resulting in fluidized Height 100mm-300mm, with the wet material in boiling rotation, allowing a full range of wet material is heated overcome the traditional static heat drying technology leads to one-sided emblem containing a small amount of technical defects finished uneven.
3) heat transfer medium heat of the machine can be used steam, plus resistance, gas, fuel oil and coal-fired heat source of a variety of media, user-friendly environment of choice.
4) This machine is designed Tornado, Tornado and Gabe bag Bag receipt and dust removal system, the user may need to produce material or process environment, to purchase.
5) The machine is designed with the drug and non-adiabatic heat two kinds of machine type. Adiabatic fluidized bed type insulation for high temperature heat production; non-adiabatic fluidized bed type insulation is not suitable for room temperature (60 ℃) dry desiccant material or low-heat-sensitive materials.
