(54) DRYER FOR GRAIN

(57) The invention relates to devices for drying grain in agriculture and in the system of harvesting agricultural products. The aim of the invention is to intensify the drying process and save energy. In the grain dryer, vertical sections 8 of drying units 3-6 and vertical bridges are made equal to each other in height, their walls are made solid, and additional air distribution chambers are formed between adjacent drying units, limited by vertical wall 12 and external walls of inclined sections 7 of drying units and vertical jumpers, with a vertical jumper connecting the drying blocks 3 and 4, connected to microwave generators 17. 1 Cp. f-crystals, 6 sludge. j

The invention relates to devices for riepiia and can be used in agriculture and in the procurement system of agricultural products.

The purpose of the invention is the drying of the drying process and saving of energy.

Figure 1 shows the layout of the equipment of the grain dryer, top view; figure 2 is a view of L in figure 1; FIG. 3 is view B of Fitch 1; FIG. 4 shows the movement pattern of the drying agent; nafi1, 5 dryer, transverse; the section in Fig.6 is a typical unit, but the incision,

The grain hopper contains an extra-dry bunker 1 of a heating plate with ganek 2, spike blocks 3-6, formed by inclined mesh sections 7 and vertical continuous lines "mesh 8 sections), in the form of hollow sheshshraniyaik, the inner space represents Air distribution chambers 9.

The drying units 3-6 are interconnected by verticals And jumpers 10, To the air distribution chambers 9 are connected Eena fans 1 1. The space between adjacent and drying blocks is closed with pert.

The vertical sections of 8 mesh columns run early along the height of the vertical JO jumpers, and their walls are asymptomatic.

The dryer works as follows.

The grain of Hopiieii 22 is fed to the bottom of the hopper 1 and, with 1) 1 of nek 2, is distributed on the sieve columns of the dry 6jHJKoD 3-6. Grain by gravity fills the npoc / rpaiici in the stacks of the columns to the screw 23. Depending on the design of the initial sepua-fit ckopnr-ri. I i o; 1 below and, respectively

The screw rotation speeds 23. Next, the fans are simultaneously turned on - 1h; from block 6. In inclined net sections of 7 columns, grain is grown by a drying agent, and in vertical sections 8 with continuous walls. - it is extracted without heat treatment; th microwave generators of G /. As a drying agent, atmospheric air, successively spent on the final 1: the air cooled, in block 6, intermediated. then in block 3, after which it is used in bunker 1 to pre-heat the grain. Saturated Hbiii E.iiai oii agent cyujKH is fed to condensers 19, in which it, while cooling, heats the water for the process technology: h ;.

The vertical walls of the vertical Y; asgkoG (columns and vertical jumpers of CHjioviHMT-tti and equal between the height of 1) allow one to carry out a pai-numbered progress of the binning of the grain of PSH. (Heat treatment nikla ti 1) and improving the quality of drying, between;, adjacent drying units, additional air distribution chambers, bounded by two mutually perpendicular and column walls, allows for an oscillating drying mode, resulting from the supply of drying agent to these chambers. the appropriate temperature intensity / dry drying process.
