Description

TECHNICAL FIELD [001] This utility model patent application pertains to the agricultural machinery segment, more specifically to an electric grain dryer, which notably features strategically distributed components to facilitate user handling. Furthermore, it allows users to dry grains without compromising machinery efficiency, thus speeding up the drying process. HISTORY OF THE TECHNIQUE [002] Before the introduction of electric dryers, grain drying was a challenging and often unpredictable task for farmers. It relied mainly on traditional methods, such as sun drying or drying in natural drying facilities. These methods were slow and subject to weather conditions, which could lead to uneven drying and loss of grain quality. [003] With the advancement of technology, mechanical dryers emerged, which were powered by fossil fuels, such as gas or oil. Although they represented an advance over traditional methods, they still had some limitations, such as dependence on non-renewable fuels and the difficulty of precisely controlling temperature and humidity during the drying process. [004] Electric dryers represent a further evolution in this context. They utilize electricity as an energy source, making them more efficient and environmentally sustainable than dryers that rely on fossil fuels. Furthermore, electric dryers offer greater control over the drying process. Farmers can precisely adjust the temperature and humidity inside the dryer, ensuring uniform and rapid drying of the grains. This helps prevent grain deterioration due to prolonged exposure to heat and humidity, reducing post-harvest losses and preserving product quality. [005] Electric grain dryers contribute to increased agricultural productivity. They can dry large volumes of grain in a short period of time, freeing up storage space and allowing farmers to have their products ready for sale more quickly. State of the Art Analysis [006] Currently, we can find a wide variety of grain dryers available on the market, seeking to streamline the production process. Research conducted in specialized databases revealed documents, such as document no. BR 10 2015 004293-0, which deals with an "INTERMITTENT GRAIN DRYER, ON PILOT SCALE, WITH ELECTRIC AIR HEATING". The present invention refers to an intermittent dryer on pilot scale for grains and granular materials, with heating of the drying air through electrical resistances. Its purpose is intermittent drying, but on a small scale, comparable to commercially available dryers, and it has the appeal of a green dryer, i.e., without CO2 emissions into the environment, and it has the possibility of varying the intermittency ratio. [007] Document No. BR 20 2020 006368-0, concerning a "MODULAR GRAIN DRYER," a utility model patent for agriculture, develops a modular grain dryer for use in grain drying systems. This dryer consists of modules with capacities ranging from 12 to 17 tons. The Modular Grain Dryer's appearance is substantially defined as shown in the attached figures, where Figure 1 shows a perspective view of a unit of the present Utility Model Patent application for a Modular Grain Dryer; Figure 2 shows a perspective view of the receiving box or upper box module; and Figure 3 shows a perspective view of the cooling box module. The Modular Grain Dryer offers a complete and simplified solution in a single piece of equipment for implementing a grain drying system. Each module, when fitted together, increases the drying capacity, eliminating the need to construct large structures for this technology. It also allows, through a simple adaptation, its use to meet the needs of small, medium and large producers alike. [008] Document No. BR 10 2022 008994-9, which deals with a “SOLAR DRYER AND GRAIN DRYING PROCESS”, the present invention refers to a solar grain dryer comprising a grain inlet (8); a grain outlet (10); a transparent roof (1) arranged in such a way as to allow heating inside the ventilated drying tunnel by means of solar rays, promoting the heating of the grains and the internal air of the ventilated drying tunnel; two opposite side walls (2) made of material capable of maintaining thermal insulation between said ventilated drying tunnel and the external environment, said side walls (2) are provided with at least one ventilation hole (3); at least one conveyor belt (7) arranged inside the tunnel and provided with at least one traction motor; at least one fan (4) provided in a first side wall (2); and at least one auxiliary sensor in determining the drying level. Furthermore, the invention provides a grain drying process associated with the solar grain dryer. Furthermore, all energy-requiring elements of the device, such as motors, resistors, and controls, can be powered using renewable energy sources, such as solar, wind, or biogas generators, but are not limited to these, in order to further contribute to reducing the environmental impact of the process.
