Abstract
With the continuous development of industrial technology, the upgrading of drying equipment also getting faster and faster. This paper is designed handling capacity of 220 T / d of milk spray drying system, because of its atomization of all the material is dry and aqueous environment in the medium is the air so the election open spray drying system, optional atomizer pressure -- Air-nozzle, a bag of dust filter and cyclone recovery, to re-granulation, the particles can be dissolved so that a better performance, improve product quality.
Through the material balance and energy balance, and dryer set operating parameters of the structural parameters, last used by the air flow through to find out. Tajikistan is a dry high-intensity, empirical formula, and then to compare selected Max, which is drying tower high tower. Tower Drive directly by the decision of the wind. Finally height and diameter than the application of accounting.
Ancillary equipment should be related to the selection of books for selection and design calculations, some of these components require the choice of national standards related components. Spray drying equipment the most important thing is atomized, atomizer to choose smoothness, and more wear-resistant and the nozzle.
In which the actual import volume of the system is empty 58050.8m ³ / h, its diameter is 7400mm, height of 21000mm; the lower part of the cone, its height is 7200mm, cone angle 55 °; with 8 nozzles,, the thermal efficiency of drying system was 56.7%。
Spray drying is to spray the liquid material into the heat of the dry powder into a medium transit materials. It is dry, including a particle materials for processing. Feeding can be a solution, suspension and paste. Liu was made of dry powder, granules or poly form clumps. Spray drying operation in many industries to meet the expected quality indicators stem the requirements for products for further processing or for direct consumer use.
