Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a ventilation dryer for inspecting grain used in grain drying facilities such as rice centers.

In the method of drying grains for inspection by ventilation in only one direction of the grain layer, uneven drying occurs in the upper and lower layers of the grain layer.
．． Kflu+l+lKshiI'+! -Hi, 4CQ, +V,
It becomes uneconomical to blow more air than necessary in order to reduce uneven drying. This invention attempts to address these deficiencies. For this reason, the present invention has taken the following technical measures. That is, drying air is supplied to a drying room (3) in which a number of drying boxes (2) that house grains for inspection (1) for inspection and allow drying air to pass through in the vertical direction are freely accessible. The ventilation direction inside the drying box (2) is set to the positive (a) and +! ! In order to achieve (b), the ventilation dryer for inspecting grains is configured to have one switching function and communicate with a suction fan (6).

Since this invention has such a configuration, it has a first-order technical effect. That is, the heated air sucked into the drying chamber (3) from the air passage (4) passes through the drying box (2) and dries the grains (1) in the drying box (2), resulting in υ1 wind. Road (5)
and is discharged by a suction fan (6). At this time, the ventilation direction inside the drying box (2) is changed between forward (a) and reverse (b).
[By switching, the flow of heated air is switched from the 4-layer side of the grain (1) to the lower layer, and from the lower layer to the 1: layer, and the 1-layer of the grain (1) is evenly dried. I can do it. As mentioned above, there is no need to take out the grains and stir them during the drying process, which is a labor-saving effect. +5 Since it involves work such as returning the grains to the drying box, scattering loss is likely to occur in grain debris, but since such work is not involved, no scattering loss occurs. Me, drying room (3)
Since the υV air path (5) of the drying chamber (3) is connected to the suction fan (6), the interior of the drying chamber (3) is operated under a negative pressure compared to the outside air, so there is no leakage of dust, etc. Suitable for work 1
, it is good (it has the effect of being able to maintain the boundary S, but this Fugetsu: is extremely large [even if it is not 7) ■ The intersection of II (a) and the opposite (b) of the two ventilation directions , it is possible to perform uniform drying with weak suction air by switching.

In addition, in the illustrated example, the drying chamber (3), the air duct (4), and the JJl air duct (5) are formed within a longitudinal frame (7), and the drying box (2) is approximately above and below the drying chamber (3). The drying chamber (3) is supported by a partition wall (8) located in the center of the drying chamber, and is placed in a position where the ventilation channel (4) and the ventilation channel (5) communicate with each other.
It is configured such that it can be freely entered and exited from the lateral space 11 (9).

The drying box (2) is a container for grains (1) with an open top and a wire mesh (10) on the bottom to allow ventilation. An intake switching valve (located at one end of the box frame (7) and corresponding to the intake port (11)
12) and tel air 11 (13) 2. Correspondingly, exhaust switching #r (+4) is integrally provided facing each other in the front and rear direction around the shaft (15), and the υ1 air +" (+3) is installed. (16) is a configuration in which the side wall of the air passage is opened and the 1-lower exhaust port (13) can be switched on the side of the exhaust switching (f (14)) formed in the J/D-shaped cylinder. Box frame with heater (7
) Provided in front of the intake port (11) at the end, and a suction fan (6)
is connected to the exhaust ITI (+3) through a cylinder (17). As shown in Figure 1, the drying air heated by the heater (16) is transferred to the intake switching valve (12) in the first position and the exhaust switching valve (1
If 4) is set to -1, the intake hole (+1) will communicate with the upper air passage (4), and the air intake hole (13) will communicate with the lower air exhaust passage (5).
), the barking wind from the suction fan (6) is
The hot air heated by the heater (16) from the intake hole (11) flows from this side air passage (4) to the drying box (3) of the drying room (3).
2) The drying box (2) is ventilated to the side, and the grains 1) are dried. The suction fan (6)--, the suction υ1 is discharged through the IJI air port (13). Also, if you operate the intake switching valve (12) and the IF air p1 switching 1t (IO in the opposite direction to 1-, the upper side will be the intake D (II
), and the lid side is the ventilation path (4) that communicates with the exhaust ITJ (
+3), and the drying hot air flows through the drying box (2). Contrary to the description, from the top to the 1- side (
b) The grains stored in the drying box (2) are dried by ventilation. As shown in 2, heated air is applied to the grains in the upward direction and downward direction to uniformly dry the grain over time.

In addition, the intake switching valve (12) and the lively LJJ switching valve (14)
It is also possible to cut the material intermittently at regular intervals using a timer, #1 structure, etc.
