Definitions

  • the invented device is suitable for drying grain crops while in storage and their quality preservation by airing, especially agricultural grain crops.
  • the described drying technologies have in common the fact that the drying process uses organic fuel (diesel oil, natural gas) to heat air in the drying device.
  • the air is heated to 70-90 ° C , blown through the drying area while the grains are being turned over.
  • the temperature of the grains can reach anything up to 65 ° C, so they lose moisture until their moisture content reaches the desired 13-14%. Following this, the grain crops are put in the storage area. Based on practical experience deficiencies in all the drying procedures cause the following:
  • Rehydration of grain crops during drying due to rapid warming which causes a sudden loss of water, the grains shrink. Then following the cooling period, after being put in storage, due to the contact with air that has a normal amount of moisture in it and a normal temperature, a reversed process starts and the grains absorb moisture from the surrounding air, the crops rehydrate. Rehydration provides favourable conditions for the development of damaging heat centres, and for an increase in fungal and insectoid infections.
  • the drying technology is undesirably slow: the permeability of common drying devices is limited, so during harvest it is the limited speed of the grain harvest, which affects the length of time needed for the execution of the technological process.
  • the alteration of the optimum permeability considering the grain crops results in a drop in the quality of the dried grain crops.
  • Grain crops have to be regarded as "living" materials, because after being put in storage, they "breathe” , i.e. they absorb oxygen from their environment, and emit carbon dioxide, while producing heat.
  • grain crops need to be aired, which according to earlier practice was simply carried out by turning over the heap of grain.
  • active airing namely by blowing over pressurized surrounding air through the heaps of grain in purpose-built storage facilities with airing platforms and in silo tanks.
  • the purpose of the invention is to eliminate the deficiencies described above, namely to create such an economical drying and quality protection airing device which simultaneously carries out the tasks of drying the grains after harvest and the preservation of their quality during storage, which is simple and economical to run and environmentally friendly. According to the set target, the device is to perform the following tasks:
  • the controllable cooler/heater climate control appliance installed in front of the insufflating ventilator has to be able to extract as much water from the surrounding air as is needed during the drying of the grain crops.
  • Sensors measuring the temperature and humidity levels of the surrounding air are to be placed in the appliance in such a way that data provided by them facilitate the sufficient control of the drying and quality protection airing process.
  • In order to carry out sufficient control it is necessary to continuously measure the temperature and moisture levels of both the dried and aired heaps of grain crops using suitable sensors.
  • the electronic control module has to check the existence of ventilation of the storage facility as well as the functioning of the airing appliances of the storage facilities, the operation of which is of vital importance to ensure that the high moisture content air that evaporates from the heap of grain leaves the storage facility environment.
  • the appliance has to have a communication device that is capable of sending out alerts, which are necessary if an event occurs which definitely requires human intervention such as leakage, cessation of ventilation, failure of the appliance, power outage, etc.
  • Assembling and disassembling the network of main pipes and permeable perforated branch pipes currently known and described above is a labour intensive and time consuming task.
  • the pipe network hinders the efficient operation of traditional loading machines in storage facilities with raised platforms. Consequently, an air- permeable platform has to be used, which is easy to assemble and does not hinder loading and emptying.
  • the pipe network referred to above is inefficient and suffers great aerodynamic loss due to the large number of colliding air flows and the numerous angled connecting sections and pipes.
  • the utilized platform has to pose a minimal aerodynamic resistance to the insufflated air, and has to transfer the drying or ventilating air into the inside of the heap of grain with minimal loss.
  • the device has to be applicable for traditional flat houses, flat houses with airing platforms and silos with airing platforms.
  • Tasks described above are carried out by the invention utilising two units that can be controlled separately, equipped with sensors measuring temperatures and humidity levels placed in front of the insufflating ventilator.
  • One of the units is an air cooler/water extractor, while the other is an air-heater device.
  • Separate sensors for measuring temperature and humidity levels are placed at the point where the surrounding air is sucked in, and where the air is insufflated past the ventilator.
  • Sensors measuring temperature and moisture content are placed in the heap of grain, thus the prevailing condition of the dried or ventilated grain has become measurable.
  • a purpose-built computer with a keyboard, a display monitor and equipped with sensors measuring temperature, humidity levels and moisture content is put in place to control the appliance.
  • the purpose-built sensor which checks whether the ventilators in the storage facility are switched on and are operational is also connected to the purpose-built computer.
  • a sysout communication device connected to the purpose-built computer and capable of sending an alert through both landline and GSM telecommunication network if necessary is also included.
  • the raised airing platform is connected to the point where the air is insufflated past the ventilator and is purposefully made up of tables that are easy and quick to assemble. These tables are made of perforated steel sheets with light-weight welded heavy duty frames. The grain to be dried is stored on top of these airing platform constructed from the tables. Thus the insufflated air is free to flow under the stored grain.
  • Wooden retaining walls stop the air insufflated under the perforated steel tops from escaping sideways.
  • the retaining walls sufficiently surround the airing platforms extending above it vertically so as to stop the grain from over flowing the sides.
  • the retaining walls are fastened to the sides of the tables which constitute the platforms and to each other, and the edges touching the concrete floors are covered with rubber seals.
  • the tables and retaining walls are sized in such a way to allow for the assembly of tables and retaining walls as needed to store the grain.
  • the airing platforms constructed in this way from smooth perforated steel sheets do not hinder the operation of traditional loading machines.
  • the device which is the object of the invention may be connected to the insufflating point past the ventilator with the use of suitable adapters not only in the case of constructible airing platforms but also when constructing both flat houses and silos with airing platforms.

  • Figure 2. shows the construction of an airing platform.
  • the appliance has an air-cooler/water extractor unit (1), and an air-heater units (2), which are connected to each other by a sealed tubulature (5).
