ABSTRACT
The current convective drying has the disadvantage - low productivity, reliability and efficiency, as due to the thin layer of material to be dried, which moves along the inclined perforated shelves, and small-time contact with a drying agent, he does not have time to go all the drying process: heating of the material, the process drying process falling drying rate and reduces the reliability of the vibration dryer. Offered dryer improves these indicators.
АННОТАЦИЯ
Существующая конвективная сушилка имеет недостаток - низкая производительность, надежность и эффективность, так как из-за тонкого слоя высушиваемого материала, который перемещается по наклонным перфорированным полкам, и малого времени соприкосновения с сушильным агентом он не успевает пройти весь технологический процесс сушки: нагрев материала, процесс сушки, процесс падающей скорости сушки, а вибрация снижает надежность самой сушилки. Предлагаемая сушилка повышает данные показатели.
Keywords: Dryer, material, mine, performance, reliability, efficiency.

Development refers to the technique of drying wet materials are highly dispersed and can be used in agriculture, food, chemical and other industries.
Convective dryer seed includes a vertical shaft with a rectangular hopper and discharge device consisting of isolated from each other by a drying agent and superposed sections with inclined perforated shelves, forming a zig-zag channel for moving the material to be dried from the hopper to the discharge device, wherein each section comprises a conductive and discharge manifolds of the drying agent and each inclined perforated shelf is a frame on which is fixed a perforated grate to form a window in its lower part over the entire width for discharging the material being dried from upstream to downstream flange, each section under window shelf in the inclined perforated windows formed in such a manner that a dried material interspersed on the top of the downstream perforated inclined shelves sloping perforated last shelf installed in the zone of the discharging device and is made without a window for discharging the material [1].
The disadvantage of this convection dryer is the low productivity, reliability and efficiency, as due to the thin layer of material to be dried, which moves along the inclined perforated shelves, and small-time contact with a drying agent, he does not have time to go all the drying process: heating of the material, the drying process falling drying rate and reduces the reliability of the vibration dryer.
The objective of development is to increase productivity, reliability and efficiency of convective drying seed.
The task is achieved by the fact that the convective dryer seed includes a vertical shaft with a rectangular hopper and discharge device consisting of isolated from each other by a drying agent and the stacked sections with inclined perforated shelves, forming a zig-zag channel for moving the material to
be dried by the hopper to the discharge device, each section contains inlet and outlet manifolds of the drying agent and each inclined perforated shelf is a frame on which is fixed a perforated grate to form a window in its lower part over the entire width of the discharge of the material being dried in the upstream flange downstream below the window in the perforated sloping shelves made window so that drying material interspersed on the top of the downstream perforated sloping shelves last perforated rack is inclined zone and the discharge device is made without a window for discharging material wherein holes are made in the perforated shelves in the form less than the smallest size of the material to be dried, which include active ripper blades mounted under the perforated sloping shelves.
The presence of active rippers, established under the sloping perforated shelves, allow to increase the layer thickness of the material being dried, reduced movement speed it down the sloping perforated shelves and increase the impact of the drying agent, which will ensure the implementation of the entire drying process.
Picture 1 shows a general view of the convective drying seed, Picture 2 - construction of perforated inclined shelves, Picture 3 - Location of active rippers installed under the perforated slanted shelves.
Convective dryers seed comprises a vertical shaft 1 of rectangular cross section, consisting of superposed three sections 2, 3, 4 (the number of sections depends on the bulk material). Each section has a perforated inclined ledge, is a frame 5 on which is fixed a perforated grate 6, 7 to form a window in its lower part over the entire width. Thus at the attachment section below the window 7 in the horizontal window shelves 8 are made so that the drying material are interspersed on the top of the downstream perforated sloping shelves. Last inclined perforated shelf made without a window.
Pic. 1. General view of the convective dryer seeds
Pic. 2. The design of the perforated inclined shelves
Pic. 3. Location of active rippers installed under the perforated sloping shelves
All perforated sloping shelves are connected to the inner wall of the shaft 1, mounted beneath the active rippers 9, the blades of which are included in longitudinal grooves 6. Width perforated grilles perforated grilles longitudinal grooves 6 is less than the smallest size of the material being dried. At each end of the active shaft sprocket 10 mounted ripper interconnected chain 11 and driven in rotation by drive 12. Sections 2, 3, 4 are connected to the outside lead-in 13 and outlet 14 manifolds drying agent. The mine is equipped with a hopper 15 for supplying the wet material and the discharge device 16.
How convective dryer seed works:
Drying material, acting through the hopper 15, stirring blades active rippers 9 and moves down the sloping shelf perforated section 2. The thickness of the layer of transported material to be dried is determined by the height of the active rippers 9 of perforated inclined shelf, and its speed is regulated speed drive 12. In this grate 6 from below through a perforated
sloping shelves with a dried material passes the drying agent supplied through the supply manifold 13, which implements drying process: heating the material, the drying process, the process of falling rate of drying. The spent drying agent coming out of the section through the outlet manifold 14.
The dried material from the upper section 2 through a window 7 falls out on the upper part of the downstream perforated inclined shelf section 3 and enters the last perforated inclined ledge that is formed without windows for unloading material and the output shaft of the discharging device 13. In the sections 3 and 4 process drying of the material is similar to the drying process in section 2.
