Description

Grain dryer The present invention relates to a grain drying device. Various grain drying devices are being used to heat and dry grains. Conventional grain drying devices are configured to heat grains primarily by utilizing direct flame, hot air, near-infrared lamps, etc., as heat sources. These conventional grain drying devices had problems such as the difficulty of heating grains uniformly, low thermal efficiency, and low maximum heating temperature, which resulted in long drying times and caused air and other environmental pollution due to high energy consumption. In addition, conventional grain drying devices had a problem in that it was difficult to control the drying pattern of the grain in real time according to the drying condition of the grain, resulting in a deterioration of grain quality. FIG. 1 is a front view of a grain drying device according to a preferred embodiment of the present invention. Figure 2 is a diagram showing the schematic structure of the supply unit illustrated in Figure 1. Figure 3 is a diagram showing the schematic structure of the guide plate illustrated in Figure 1. Figure 4 is a diagram illustrating the schematic structure of a laser unit. Figure 5 is a block diagram illustrating the schematic structure of the analysis module. Figure 6 is a diagram illustrating a laser beam having a Gaussian beam profile. Figure 7 is a diagram illustrating a laser beam having a flat-top beam profile.

It should be noted that in assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the embodiments of the present invention, if it is determined that a detailed description of related known components or functions would hinder understanding of the embodiments of the present invention, such detailed description is omitted. In describing the components of the embodiments of the present invention, terms such as first, second, A, B, (a), (b), etc., may be used. These terms are intended merely to distinguish the components from other components, and the essence, order, or sequence of the components is not limited by the terms. Furthermore, unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application. FIG. 1 is a front view of a grain drying device according to a preferred embodiment of the present invention, FIG. 2 is a diagram showing the schematic structure of a supply unit shown in FIG. 1, FIG. 3 is a diagram showing the schematic structure of a guide plate shown in FIG. 1, and FIG. 4 is a diagram for explaining the schematic structure of a laser unit.

Since this controller has the same configuration as a conventional controller, a detailed explanation thereof will be omitted. Next, the supply unit (10) is a device for consistently supplying a certain amount of grain (F0) per unit time. As illustrated in FIG. 2, the supply unit (10) may be equipped with a hopper (12) into which grain (F0) is fed, and a supply amount regulator (14) that supplies a certain amount of grain (F1) that has passed through the hopper (12) to a conveyor unit (20) to be described later per unit time. The hopper (12) has the same structure as a conventional hopper for supplying materials, so a detailed description thereof will be omitted. The supply volume regulator (14) may have a main frame (14a) and a guide member (14b), etc. The main frame (14a) is provided so that grain (F0) passing through the hopper (12) can be temporarily stored inside the main frame (14a).
