(57) Invention m. used for drying dispersed materials, herbs and plant materials. The purpose of the invention is to increase the productivity and quality of drying. The chamber has loading and unloading devices 2 and 3 and closed conveyors placed inside it, combined into upper and lower groups 5 and 6. In group 6, the conveyors are installed in a checkerboard pattern, and in group 5 they are equipped with individual drives and are displaced by one relative another from the top to the bottom of the device 2. The device 2 is equipped with a raw material distributor for each conveyor of group 5. A pouring shield 8 is installed between groups 5 and 6. The design of the dryer allows, due to a stepwise increase The efficiency of drying each of the downstream streams relative to the upper one compensates for a decrease in the drying potential of the heat transfer medium and ensures the possibility of drying the high-moisture thermosensitive raw material. 2 Il.

; The invention relates to a drying technique and can be used to dry various dispersed materials, such as bark, greenery and others. vegetable raw materials.

. The aim of the invention is to increase productivity.

Figure 1 shows a dryer of a plant material, a general view; in figure 2, top view. ; The dryer for plant material L contains an extension chamber I with a loading device 2 (conveyor) and an unloading device 3, closed-type conveyors 4 placed inside the chamber I, combined into the upper and. lower groups 5 and 6, and in the lower group 6 transport terraces are installed in a staggered order. In the upper group 5, conveyors 4 are equipped with individual drives (not shown) and are shifted one relative to the other in the downward direction to the loading device.2, which is equipped with A raw material distributor 7 I per each conveyor 4 of the top I group 5, and between groups Z and b of the conveyors 4 there is installed an adjustable access panel 8. The dryer also contains fans 9 and remote: radiators 10.

Suposhka works as follows.

By the loading device 2, the raw material is fed to the distributor 7 of the raw material, I dividing it into a TFI flow, coming in; The three upper conveyors 4 of the upper group 5, which move the raw materials along the drying chamber 1 to the unloading device 3, the raw material flows successively into the zones into which the heat carrier heated in the heaters 10 is pumped by the fans 9, and its temperature is stepwise decreases from 90-160 ° C in the first zone to 40-601: in the latter, depending on the permissible heating temperature of the raw material,

potential of the heat carrier passing through the upper feedstock flows decreases (its temperature decreases and moisture content increases), which is compensated by a stepwise increase in the drying time of each of the downstream streams relative to the upper one in the ratio from l: I, 2jl, 6 to 1: 1.5: 2.0.

In order to provide the possibility of drying the high-moisture thermosensitive raw material after the last conveyor 4 of the upper group 5, an adjustable pouring shield 8 is placed, which in one position directs the raw material to unload from the dryer, and in a different position to the lower group 6, to the lower conveyor 4, placed in a checkerboard, and the direction of movement of each of them, starting, for example, from the fourth, also changes in the opposite direction.

The proposed dryer allows to increase the productivity and quality of drying.
