Abstract

PURPOSE:To shorten the total length of a drying machine by detouring a part of discharging air, ventilated through a drying chamber, to a fore end from the bottom of an air discharging chamber to suck and discharge it by an air discharging machine and to make charging work effective by providing grain collecting troughs at both of the left and right sides of the body of the title machine. CONSTITUTION:Hot airflow is divided into two hot airflows and one of which is ventilated from a hot air passage chamber 8 through an air sending chamber 1 and a central drying chamber 3 and sucked directly by an air discharging machine 4 through an air discharging chamber 2 at the upper side of a central section, the suction port of a partitioning plate 18 and the air discharging chamber 2 at the lower part of the central section while the other of which is ventilated from the hot air passage chamber 8 through the air sending chamber 1 and outside drying chambers 3 while detouring an outside air discharging chamber 2, the suction port 22 of the partitioning plate 21, grain collecting troughs and an air discharging passage chamber 24 and is sucked from a lower side air discharging chamber 2 by the air discharging machine 4. Grains, stored in a reserving chamber, are exposed to hot air and are dried while flowing down from the reserving chamber through the drying chambers 3, delivered to a lower part by a delivery valve to made them flow down and supply them into respective grain collecting troughs, then, are transferred to the upper part of the title machine by a bucket conveyer to diffuse and return them uniformly into the reserving chamber to dry them by circulation.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a grain dryer for drying grain.

Conventional technology In the past, multiple drying chambers were provided in which grains were heated and dried by passing hot air from the ventilation chambers on one side of the left and right to the exhaust chamber on the other side while the grains were flowing down. It was a grain dryer that discharged air directly to the exhaust fan at the end.

Problems to be Solved by the Invention While the grains housed in the storage chamber are fed out from the storage chamber into each drying chamber and flowed down, the hot air generated from the burner is passed through each drying chamber through each ventilation chamber. The grains flowing down in each drying chamber are exposed to this hot air and dried.

During this drying process, the grains are exposed to the exhaust air after passing through each drying chamber to improve drying efficiency, or the air from each exhaust chamber is directly used by an exhaust fan. The overall length of the dryer is shortened by having a configuration that allows air to be sucked in or detoured to the front, and the grain tensioning work can be carried out from both the left and right sides of the machine in an attempt to improve the efficiency of grain tensioning work. It is.

Means for Solving the Problems This invention provides ventilation chambers (
A plurality of drying chambers (3) are provided for heating and drying by blowing hot air from 1) to 2) in the vL air chamber on the other side. (・1) Directly to the side, the remaining ventilation chamber (2) is connected to the ventilation fan (4) from the bottom.
The grain dryer has a configuration in which the front end of the exhaust chamber (2), which communicates with the grain dryer, is connected in a detour to the front end.

Effect of the Invention While the grains accommodated in the storage chamber are fed out and flowed down from the storage chamber into each drying chamber (3), the hot air generated from the burner is sent from each ventilation chamber +11 to each drying chamber (3). ventilation,
Furthermore, some of the ventilation chambers (2) through which this ventilated haiku passes are directly suctioned and exhausted by the wind fan (4), and the remaining ventilation chambers (2) are Air is detoured from the bottom of this exhaust chamber (2) to the front end and sucked and exhausted by the exhaust fan (4).

The grains flowing in the flow F in each of the drying chambers (3) are exposed to this hot air and dried, and at the same time are also dried by the haiku air.

Effects of the Invention According to this invention, some of the haiku air ventilated through the drying chamber (3) detours from the bottom of the ventilation chamber (2) to the front end and is sucked and exhausted by the exhaust fan (4), thereby eliminating this detour. During the process, the grains are exposed to the haiku, which improves the drying efficiency of the grains by exposing them to the exhaust air from the hot air. Wind machine (4)
is attached to the rear end of the machine, shortening the overall length of this dryer.

For this reason, the installation of this dryer in the workplace is more adaptable, and the dryer can also be installed in the drying room (3). 21'iL Grain collecting troughs for receiving flowing grains are installed on both the left and right sides of the machine, making it possible to load grains from either side, making the loading process easier. Became efficient.
