Purpose of the development: For drying all types of thermostable and thermolabile dispersed materials.

Recommended application field: In the chemical, food and agricultural industries.

Advantages over analogues: Development provides: - the creation of a countercurrent mode of movement of interacting flows, which is the most effective and provides the highest value of the average driving force; - the possibility of simultaneously carrying out the drying process and the classification of the material in one apparatus; - reducing the size of the apparatus by creating separate stages of the contact flows in the volume of one apparatus; - organization of a differential regime of dehydration of dispersed material - the creation of compressors and thermodynamic drying conditions at each stage, depending on the temperature and temperature characteristics of the dispersed material and the drying agent; - the ability to control the residence time of the dispersed phase in the apparatus by changing the technological characteristics of the drying process and the design parameters of the dryer; - the secondary use of the drying agent can reduce energy costs for the process. As a result of the differential dehydration regime, an increase in the rate and efficiency of moisture removal by 3-5% was achieved with constant energy consumption and the preservation of the quality indicators of the finished product.

The development stage readiness: Ready for application

Description of the development:
()
Multistage gravity shelf dryer - a new design of drying devices with stable hydro and thermodynamic parameters, achieved by vertical sectioning of the internal space due to the installation of a cascade of perforated shelves at a certain angle; this creates conditions for the gravitational movement of the material along the shelves and its filling from one shelf to another. On each of the shelves in this design an effective mixing characteristic of the fluidized bed is created, while maintaining the advantages of an organized counterflow regime.
