Abstract

Grain dryer, into which the moist grains are introduced in the upper part to emerge dry in the lower part and which comprises, buried in the mass of grains, open sleeves (4) arranged in rows and connected in some cases to a hot-air source and in others to a moist-air exhaust pipe. The upper part (5) of the lateral walls of the sleeves comprises holes or perforations and each sleeve is divided by a sheet (8) into two spaces (6 and 7), one of which is connected to a hot-air source while the other is connected to a spent-air exhaust. <IMAGE>

Description

The present invention relates to a seed dryer. The wet core is fed into the top of the unit and the dry core is discharged into the bottom of the unit. The inserts (4) open in the core mass. One part of the inserts (4) arranged in rows is connected to a hot air source and the other part to a dehumidifier. There are holes in the upper wall portion (5) of the side walls of the inserts (4). The insert (4) is divided by a plate (8) into two spaces (6 and 7). One is connected to a hot-air source and the other space is connected to a used air outlet. The A-Wine Provider prevents the drying of the - seeds - over-salting of the ancestor - (Figure 2)

FRANCIAQRAZÁC-

The present invention relates to a seed dryer. In a continuous seed dryer, the wet core is introduced into the upper portion of the apparatus, the dry core is introduced into the lower portion of the apparatus. ·· ·· · ·

- 2 leaving. The core masses are exposed to open inserts arranged in rows. Some of the inserts are connected to a hot air source and the other part to a dehumidifying duct.

The inserts are zigzagged, most of which are open at the bottom and V-shaped at the top.

Air outflow is often a problem with this type of equipment. The air overheats the cores in the vertical layers when the horizontal rows of the pads alternate between rows or in the horizontal layers when these rows alternate between the two rows of blocks.

It is an object of the present invention to provide an improved seed drying apparatus that limits overheating and makes the drying of seeds even.

This object is achieved according to the invention by having holes or perforations in the upper side walls of the inserts and dividing each insert into two spaces. One space is connected to a source of hot air and the other space is connected to a used air exhaust duct.

Preferably, the disc dividing the insert into two spaces is inclined so that one end is at the base of the insert and the other end is substantially at the base of the perforated wall portion of the side walls of the insert.

Here is an example of our invention! Embodiments of the invention will be described in more detail by means of the drawings, of which

Figure 1 is a schematic sectional view of the seed dryer, a

Figure 2 is a Perspective view of two superimposed inserts, a

Figure 3 is a sketch showing the air circulation.

As shown in Figure 1, the apparatus according to the invention has a vertical casing 1 with a filling opening 2 on its upper part and drain funnels 3 on its lower part.

The casing 1 has horizontal inserts 4 along its entire height, but may also be provided with so-called drip sections 5a and 5b without inserts.

The bottom part of the inserts 4 is open, their side walls are sloping and thus have a V-shaped cross-section. The inserts are zigzagged.

As shown in Fig. 2, the upper wall portion 5 of the side walls of the insert is formed by a grid or perforated plate or otherwise formed so that air can penetrate there but hold the cores. Each insert is divided into two spaces 6 and 7 by a plate 8 without holes, which is inclined so that one end is at the base of the insert and the other end is substantially at the base of the perforated wall portions 5 of the side walls. The two ends of the inserts are open so that the upper spaces 6 are connected to a hot-air source, while the lower spaces 7 are connected to the exhaust air duct 6 at the opposite end of the insert. The spaces 6 are closed at their opposite ends to the intake of hot air. During operation, hot air enters the inserts 5 at the location indicated by the arrow fi, distributes them in the spaces 6 and exits through the perforated wall portions 6. A portion of this air passes vertically through the cores and passes through the space marked by arrow f2 into the spaces of the upper inserts, and then exits to the space opposite the hot air side of the core drying apparatus, indicated by arrow f3. The remainder of the air exiting through the perforated wall portions 5 of the insert surrounds the insert, penetrating into space 7 <

- Leaves at the 4 and f4 arrows at the base of the insert.

The placement of the air inlet and air outlet locations is reversible with respect to the examples described. The warm air can be introduced into the lower part of the inserts and can be discharged through the perforated plate on the upper part.
