The present invention relates to a hot air direction control device of the agricultural product dryer.

In general agricultural product dryers, a heat exchanger having a heating means such as a burner and a heat exchanger in which a blower is stacked on one side of a drying chamber of a predetermined width is installed, and the air flowing downwardly through the blower is hot-aired by the heat exchanger, and then a lower vent. By allowing the leaf tobacco to enter the drying chamber through, the tobacco leaf roughening process in the drying chamber is to be made.

In a conventional agricultural product dryer having such a configuration, a drying chamber for drying rice, red pepper, etc. is generally manufactured in a rectangular box type using a heat insulation panel having a predetermined thickness, and a long vent is formed at a lower side of one panel. The hot air flows from the heat exchange chamber so that the hot air flow rate may be somewhat smaller than the central portion, that is, the front and rear side portions of the drying chamber, which are located outside the both ends of the ventilation holes. On the other hand, the hot air generated by the rotation of the blower located in the upper side of the heat exchange chamber is introduced into the drying chamber as a vortex in the rotational direction of the blower, and thus the radius of rotation of the hot wind introduced into the vortex state. Hot air is applied to the side part located outside, that is, the inside side part of the front panel or the rear panel. The effect of this will have to be somewhat lessened, and if this differential phenomenon persists, it will not be possible to expect a uniform drying effect of the entire agricultural product put into the drying chamber.

In order to eliminate such uneven drying phenomenon of agricultural products, a conventional method is to install a plurality of hot air induction plates whose ends are curved to the front and rear panel sides by fixing them to a dry bottom plate placed in front of the ventilation openings to the heat exchange chamber. The hot air flowing in from the front panel is distributed evenly to the front and rear panel side to get the effect of eliminating uneven drying phenomenon, but this method does not consider that hot air flows into the vortex state along the rotational direction of the blower. Inequality phenomena in which hot air is concentrated on either side of the front and rear panels that coincide with the vortex direction cannot be excluded.

The present invention has been devised to effectively solve this problem in view of such a conventional problem, and provides a simple way to adjust the position of the hot-air induction plate according to the situation from the outside to prevent partial deflection of the hot air flowing into the drying room. By effectively excluding it, the main purpose is to obtain a uniform drying effect of the entire agricultural product, the configuration and the resulting effects will be described in detail based on the accompanying drawings.

As shown in FIGS. 1 to 4, a heat exchange path 2 having a heating means such as a burner, and a heat exchange chamber 4 having an air blower 3 installed thereon are installed at one side of the drying chamber 1, and a blower is provided. (3) after the wind flowed down by the heat exchange path (1) is hot-air, the heat direction control device of the agricultural product dryer (10) to be introduced into the drying chamber (1) through the ventilation opening (5) on one side In forming, a plurality of hot air induction plate 11 whose end portion is properly bent toward the front and rear panels 1 'and 1''of the drying chamber 1 are formed. The fixed length 12 is fixedly fixed to the fixed rod 12 of the steel beam, and the fixed length 13 is fixedly installed on one side center of the fixed rod 12, and at the same time, the handle 14 'is adjusted to the proper length of the refraction portion. ) Is connected to the fixing section 13, and the hot air guide plate is fixedly installed on the bottom plate 1a located at the front side of the vent port 5 of the leaf tobacco drying chamber 1 by fixing it. By guiding the sliding means of the guide (12) fixed to the fixed stand 12, the position of the hot air induction plate 11 through the handle (14 ') of the adjusting section 14 exposed to the portion of the agricultural product dryer (10). It is configured to be controlled externally.

Unmarked, 16 is a reinforcement bar, 17 is a guide bushing between adjustments, and 18 is a positioning nut between adjustments.

According to the present invention having the above configuration, the guide 12 is fixed to the guide rail 15 fixed to the bottom plate la in front of the vent 5 so that the left and right movements can be made freely, and the adjustment period 14 ) Is a simple process of connecting to the fixing rod 13 fixed to the center of the holder 12 while inserting the handle 14 'to the rear panel side of the heat exchange chamber 4 with the knob 14' positioned outside. In this state, the position of the hot air induction plate 11 is properly adjusted through the adjusting section 14 while considering the side conditions such as the wind speed of the hot air according to the rotational direction of the blower 3, the vortex state, and the drying chamber width. After adjusting, the drying process can be performed.

As described above, the present invention adopts a simple scheme to arbitrarily adjust the position of the hot air induction plate installed in the ventilation hole from the outside to dry the agricultural products of the one-time drying target put into the drying chamber as a uniform state as a whole. It is a profitable design for processing.

Claims (1)
