Description

one

Dryers for agricultural products are known, comprising an annular rotating chamber with a perforated bottom for introducing the heat transfer medium into the layer of material to be dried, the central shaft and the discharge device.

The drawbacks of such dryers are the complexity of the design and the lack of operational reliability.

Dryers for agricultural products are also known, containing an annular rotating chamber with a perforated bottom, in which the shaft is fixed, and the unloading device is rigidly fixed to it with a clamp during unloading of the dried material and with the possibility of rotation together with the drying chamber during the drying period.

Such dryers are more reliable in operation, however, they also have a constructive complexity.

The purpose of the present invention is to simplify the design.

This goal is achieved by the fact that the camera is fixed, and the shaft is placed along its entire height, and the loading conveyor is equipped with a distributor connected during loading to the upper end of the shaft.

FIG. 1 schematically shows the dryer described in longitudinal section; in fig. 2 - dryer in the plan.

The dryer contains an annular chamber 1 with a perforated bottom 2, under which

there is a cavity for the heat carrier introduced through the pipe 3 from the heat fan installation (not shown in the drawings). Inside this cavity there is an insulated radial cial in which the conveyor 4 is located. Above the conveyor in the central opening of the bottom 2 an inclined tray 5 is located. an unloading device 7 of the type, for example, a valuable saw and a platform 8 with a distributor 9, which is made, for example, in the form of a conveyor, moving in

a radial direction relative to the platform 8. A material transporter 10 is provided to iodine the material to the distributor 9. The unloading device 7 has a support 11 movable relative to the bottom 2 and a flap 12 for

sealing the gap between the bottom 2 and the inner wall 13 of the drying chamber.

The operation of the dryer is as follows. Flax heap or other material is fed by the conveyor 10 to the distributor 9, which, rotating with the shaft b and moving radially along the platform 8, evenly fills the layers in layers. At the time when loading is not performed, platform 8 can be disconnected from shaft 6. Heat carrier is fed under bottom 2 and passes through a layer of material. When the lower layer of the material reaches standard humidity, the drive of the unloading device 7 is switched on and connected to the shaft 6 by means of a clamp. The unloading device 7 (chain saw) rotates together with the shaft and selects the material on the tray 5 from bottom to bottom. the conveyor 4 and is supplied last to the heap-separation machine (not shown). The dryer can be loaded at the same time as the unloading.
