Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a drying device that dries a grain or the like to a set moisture content in a stationary state.

[0002]

[Prior Art]

 Conventionally, there has been a technology of drying a paddy or a potato, which is placed in a drying chamber, by supplying a room temperature and constant humidity air from the bottom of the drying chamber by a blower to form a dehumidifier that forms a room temperature and constant humidity air.

[0003]

[Problems to be solved by the device]

 In the above-mentioned prior art, non-dry matter is likely to be unevenly dried by continuously performing drying work, and it is necessary to move the non-dry matter during the drying work, which improves the drying efficiency and simplifies the drying work. However, there is a problem that it cannot be easily implemented.

[0004]

[Means for Solving the Problems]

 Therefore, the present invention is provided with a dehumidifier that forms room temperature and humidity air by the air from the drying chamber in which the non-dry matter is placed, and a blower that sends the room temperature and humidity air of the dehumidifier to the drying chamber. It is characterized in that the air pressure equalizing flat plate is installed in the air-conditioning chamber, and the air at constant temperature and humidity from the blower is supplied to the inside of the drying chamber through the air pressure equalizing flat plate. Since the moist air is blown out evenly, the non-dried product can be dried uniformly even if the continuous drying time is longer than before, and the quality maintenance control of the non-dried product can be performed easily. It is possible to easily improve the drying efficiency and simplify the drying work.

Further, a perforated plate (8), which is a wind pressure equalizing flat plate having a large number of outlets (7), is stretched over the bottom of the drying chamber (2), and a machine casing (1) bottom plate and the perforated plate (8) are provided. ), An air supply chamber (9) is formed, and the air in the air supply chamber (9) is dispersed by the air straightening plate (10) on the upper surface of the bottom plate of the machine casing (1) and the air outlet (7) to dry. While moving to the chamber (2), an exhaust duct (11) is provided on the upper surface of the machine casing (1), the duct (11) is opened to communicate with the upper part of the drying chamber (2), and the air in the drying chamber (2) is opened. It is configured to be moved to the duct (11).

Further, the dehumidifier (14) and the blower (15) are mounted on a carriage (13) having wheels (12) for movement, and a cooling and dehumidifying evaporator (16) and a room temperature restoring condenser are provided. (17), a scroll compressor (18) for stepwise adjustable output, and the like are provided in the dehumidifier (14), and the atmosphere (wet air) is taken in through the dehumidification adjustment flaps (19). An intake duct (20) is provided, and the room temperature dehumidified air from the condenser (17) and the atmosphere from the duct (20) are mixed via the constant humidity dampers (21) and (22) to obtain the room temperature and constant humidity air. Is formed, and the room-temperature and constant-humidity air is sucked into the blower (15) through the suction duct (23).

A dry air circulation duct (24) communicating with the intake side of the evaporator (16) and the intake side of the air intake duct (20) is provided, and one end of the duct (24) is connected to a dehumidifier ( 14) integrally connected to the exhaust duct (11) via the flange joint (25) so that the other end of the duct (24) is detachably connected to the duct (24) and the air supply chamber (9). An air supply duct (26) communicating with the air supply duct (26) is provided on the lower side of the machine casing (1), and a blower port (27) of the blower (15) is separated from the air supply duct (26) through a flange joint (28).
