Definitions

  • the present invention relates to an apparatus for mechanized grain drying.
  • the proper drying of the grains is carried out to achieve a quality of the grain that guarantees the conservation of the grain while marketing.
  • drying is the removal of moisture from the product until an adequate degree of humidity is reached. This process must be carried out immediately after the collection, washing, or wet process of the grain.
  • This equipment includes a thermal collector that converts solar energy into thermal energy.
  • This equipment has a heat transfer system.
  • the solar thermal collector is positioned in front of the light source and is thermally connected to the heat transfer system, in this way the heat is maintained in the drying chamber.
  • This chamber consists of a heat escape port and a moisture escape port. The beans are kept in the chamber until the optimum level in grain drying is reached.
  • WO2002061356A1 An example of a known apparatus is shown in WO2002061356A1. More specifically, a device is described that aims to achieve the drying of different foods such as onions, tobacco, cereals, etc. This is based on a small house-shaped system, where the flow of fresh air is heat with solar heat and with a small oven and once hot the air goes to a drying chamber where the food is. Solar collectors are placed on the roof of the house.
  • thermosolar dehydrator consisting of a plurality of perforated trays, vertically separated where the food to be dried is placed. Sunlight is allowed to enter the enclosure and the air that passes through the drying chambers is heated so that the food placed on the perforated trays is dehydrated.
  • US7748137B2 describes the use of a barn as a stove that heats the grains, using solar energy for auxiliary heating. It is characterized by the shape of a barn and the roof of the same allows the passage of sunlight. It has a dehumidification chimney.

  • the container is easy to empty, fill and reuse. It is mainly a mechanical system.
  • document US6209223B1 presents a grain drying system with high dehumidifying efficiency and with modular drying hoppers.
  • This system is efficient and environmentally friendly, it is used for grain drying. It consists of two main parts: the hot air generator for drying and a modular portable drying hopper.
  • Another novel aspect is the incorporation of a chimney as an anti-pollution device.
  • the hot air generator can operate with sources of electricity, gasoline, diesel, biomass or solar energy.

  • the cylinder will change color, so that one color will provide a higher temperature for drying and another color will provide a lower temperature for optimal grain drying.
  • This color change is achieved through a movement of two cylindrical walls of different colors that can be moved on the cylinder. The movement of said walls is generated manually by a crank.
  • the cylinder comprises a bottom cover where a seed collector is placed that allows obtaining test grains for a user to determine if the grain has reached the optimum degree of drying.
  • the cylinder inside will be able to maintain a temperature, which will depend on the degree of humidity that is needed as well as depend on the time in which the grain is dried, this is achieved by varying the internal temperatures of the cylinder according to the color of the cover used on the top of the cylinder.

  • the apparatus comprises a cylinder (11) inclined and vacuum closed, susceptible of rotating on its longitudinal axis.
  • the temperature inside this cylinder (1 1) depends on the color of its outer surface.
  • these colors are in a range between white and black, which will allow working with temperatures between 32 ° C and 70 ° C.
  • the main function of this apparatus is the drying of grains, these grains are introduced inside the cylinder (11) and dried through the sun's external surface exposure of the cylinder (11), where the internal temperature of this one from changes in the color of the exposed surface, doing this manually.
  • the upper half of the cylinder (11) may change color as it will consist of two metallic cylindrical walls of different colors transferable on the cylinder (11).
  • One of the walls is painted white and the other black, which when exposed to the sun will change the temperature. Both walls are moved around the cylinder manually using a crank operated by a user.
  • FIG 1 a general side view of the apparatus is shown, comprising a vacuum pump (1) which is constantly sucking air from the inside of a cylinder (11) to create the vacuum within it, a small tube (2) that passes through a first block (3) that connects the vacuum pump (1) with the inside of the cylinder (11), the vacuum pump (1) that creates the vacuum inside the cylinder (11) It is powered by electrical energy generated by solar panels (10).
  • a water connector (4) that allows cold water to be fed into a radiator tube (5) that longitudinally crosses the inside of the cylinder (11), where the water comes out at a temperature higher than at the inlet temperature.
  • the lower part of the radiator tube (5) is in contact with a channel (9) that collects and transports the water produced by the condensation of the vapors.
  • Both the channel (9) and the radiator tube (5) pass through a second block (6) to drive the water that transports outside the cylinder (11), this water is stored in a cubicle (7) located outside the cylinder (eleven).
