Existing drying equipment, the most is convection heat transfer drying. Such as hot air drying, hot air and the material to be dried in contact with heat exchange to evaporate moisture. Convection dryer representative of the common types of equipment air suspension dryer, such as fluidized bed dryer, flash dryer, air dryer, spray dryer, ventilated dryer, flow dryer, air rotary dryer, stirring dryer, parallel flow dryer, rotarius dryer et sic in {II}}

The most common way to dry powder, granule and flake materials is to apply hot air or gas flow on the surface of the granule. The passing gas stream transfers heat to the material, causing the water to evaporate. The evaporated water vapor goes directly into the air to be taken away, to the drying system commonly used drying media are air, inert gas, direct combustion gas or superheated Steam {{II}}
The method makes the hot air and material direct contact, while heating and removing water. The key is to improve the contact area between the material and the hot air to prevent the hot air bias flow. The temperature of the material during the constant speed drying is almost the same as the wet bulb temperature of the hot air, so the use of high temperature hot air can also be used to dry heat-sensitive materials. This drying method drying rate is high, less investment In apparatu, sed scelerisque efficientiam est humilis, quae sequuntur est basic situ de variis generis convectio siccatio Equipment {{}}
(I) Box-genus siccior
It is one of the oldest dryers. The material is loaded with the plate, the plate is placed in the frame car layer by layer discharge into the steam or electricity as a heat source, the hot air in the box can be circulated and part of the discharge, in order to make the drying more uniform. Although the thermal efficiency is low, but still in a large number of use, but also continue to manufacture, because the structure is simple, the Operatio non saepe curare non obvious problems {{II}} Sed multum materia siccatio ad conversus in laminam, turn in pulveris, sed etiam non adhibere ad siccitatem, cumulare, et non est in calorem, quod est humilis} {}}}

(IV) multi-iacuit Turbine Dryer
Its structure is a vertical garden cylinder, equipped with a number of layers of turntable, the material can be added from the top, layer by layer down to the bottom of the release. Hot air from the bottom of the introduction, set up in the center of the cylinder by a number of blower turbine impeller segmentation cycle air, and the corresponding height of the inner wall of the heater to supplement the heat of the air to improve thermal Efficens et siccatio rate {{I}} Sed et apparatu non facile ad mundare, quia productio multorum varietates et postulationem mundum materiae est difficilius {{II}}
