Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grain humidification conditioning device and method of using the same.

Conventionally, when humidifying and conditioning over-dried grains that lack moisture to a standard moisture content, the humidification time and non-humidification time were set separately, and the non-humidification time was set significantly longer than the humidification time. It has become common practice to repeatedly pass grain through these two types of treatment steps, and to set the latter more aggressively and for a longer period of time than the former. Such conventional equipment intensively adds moisture to the grains in an excessively humid manner compared to the total amount of moisture required to be applied to the grains within the same time period (one circulation time of the grain tank). Since a large amount of moisture is partially humidified on the grain at once, there is a risk that excessive moisture will be added to the grain surface at the time of addition, resulting in cracks on the grain surface. Even if a tempering time is provided, it is completely meaningless.

Therefore, the present invention constantly averages the necessary amount of moisture applied to the grains within the same time period (one circulation time of the grain tank) to the whole grain amount, performs mild and safe humidification, and eliminates drafts. A slight tempering time is provided by the grain layer, which acts as a canopy to prevent moisture, and moisture is equilibrated. Grain humidification conditioning that can safely and efficiently humidify a fixed amount of moisture within the same amount of time without causing crack damage due to excessive moisture absorption or uneven moisture on the grain surface. The purpose is to provide a device and a method for its use.

To explain the present invention with reference to embodiment diagrams, grain tank 1
In the lower part of the non-humidification tempering device 2 provided in the upper layer, a large number of vein umbrellas 3 and 4 having a mountain-shaped cross section are hung in parallel on both side walls 5 and 6 of the grain tank 1 horizontally or with a gentle slope. A large number of through holes 7 are provided in one side wall 5, and the other end is closed to form two types of moisture supply and exhaust paths, which are arbitrarily and appropriately mixed and arranged. However, air supply chambers 8 and 8A are provided, and when the amount of grain is small, the air supply chamber 8 is closed to stop the ventilation of a humidifier connected to the air supply chamber 8. A striated umbrella 4 forming an exhaust path faces a through hole 10 provided in the other side wall 9, and a striated umbrella 3 forming an air supply path is connected to the through hole 7 to form a humidification conditioning device 11.
A non-humidifying conditioning device 12 is provided at the bottom of the humidifying conditioning device 11 of the grain tank 1, and a discharge valve 14, 15, 16 of a rotary impeller is connected to the discharge port 13 at the bottom of the humidifying conditioning device 11.
The grains flowing down from the discharge port 13 are fed to the grain feeding section 19 of the grain tank 1 by a grain lifting machine 18 via a screw conveyor 17. A scatterer 20 is rotatably mounted on the upper non-humidifying tempering device 2 of the grain tank 1 in order to uniformly flow down the grains. The air supply chamber 8 has an air passage 22 equipped with an electric heater 21.
The air passage 22 is connected to a humidifier 23 such as an ultrasonic humidifier or a steam generator, and a blower 24. The heat exchanger 26 of the boiler 25 may be used as the electric heater 21 in some cases. In this embodiment, since a large amount of heat is required for preheating, a boiler 25 is used, and an electric heater 21 is used for adjustment, and the control circuit 28 of the heat retention thermometer 27 adjusts the amount of heat to an appropriate amount. When the moisture content of the grains reaches a predetermined value, the grains in the grain tank 1 are taken out and measured, and the rejected grains are sent to the grain lifting machine 18 and returned to the automatic moisture meter 29, a humidifier 23, a blower 24, a boiler 25, A signal is sent to the electric heater 21 etc. to stop the action.

The electric circuit of this device will be explained with reference to FIGS. 3 and 4. Figure 3a shows the circuit of the automatic moisture meter 29, in which the output side of the moisture detection sensor 30 is connected to one terminal on the input side of the comparator 32 via an amplifier 31, and an arbitrary moisture value is input to the other terminal. A setting device 33 to be set is connected, and an electromagnetic relay _R2 activated by a coincidence output signal is connected to the output side of the comparator 32, and 34 is a meter thereof. Further, b is a circuit of the heat retention thermometer 27, which connects the output side of the temperature detection sensor 35 to one side terminal of the input side of the comparator 37 via the amplifier 36, and sets an arbitrary temperature value to the other side terminal. Connect the setting device 38, and
Electromagnetic relay activated by a matching output signal on the output side
Connect R ₃ and 39 is its meter.

The electric circuit shown in FIG. 4 includes an automatic moisture meter 29 installed between power terminals R and S, and a temperature control circuit 36, 37, connected in series with a contact _R2 and an electromagnetic relay _R1 , which are opened and closed by the signal output of the automatic moisture meter 29. 38 connects the electric heaters 21 in series, and the switch of the boiler 25 is a contact point.
R ₃ are connected in series and connected between both busbars, and contact R ₁ is opened by excitation of electromagnetic relay R ₁ .
is provided on the R side bus bar between the electromagnetic relay R1 and the heater ₂₁ . Furthermore, if a control circuit for adjusting the amount of heat generated by the heater is provided in the circuit of the thermometer, it is effective to completely prevent the occurrence of humidification spots on grains and to improve the humidification performance. Therefore,
When the measured value of the automatic moisture meter 29 reaches a predetermined moisture setting value, the electromagnetic relay R ₂ is energized and its contacts R ₂ ,
Electromagnetic relay R ₁ , heater 2 via its contact R ₁
1 and the boiler 25 are stopped, and when the measured value of the thermometer 27 reaches a predetermined temperature setting value, the electromagnetic relay _R3 is energized to open the contact _R3 and the boiler 25's heat generating action is stopped. This has the effect of automatically and accurately mass-producing high-quality tempered grains.

Note that the direction of the humid air passing through the humidification conditioning device of the present invention may be changed.

In addition, the grains are uniformly supplied to the entire surface of the grain tank 1 by the scatterer 20, and the grains are distributed between the veins 3 forming the air supply path and the veins 4 forming the exhaust path, which are arranged alternately. Flows down to prevent spotty flow, and all grains uniformly absorb moisture in the form of mist. Note that the temperature of the water in the ultrasonic humidifier 23 can be adjusted.

As described above, according to the present invention, there is no excessive humidification during the intensive humidification and tempering time, which is longer than the non-humidification time, and a slight non-humidification process is provided in the upper layer of the humidification device. Even if the amount of grains in the system is insufficient, the grains can cover the humidifier and prevent moist air from blowing through.

The present invention is equipped with a grain tank in which empty chambers for the non-humidifying and refining process are connected as a non-humidifying and refining device above the striated humidifying and refining device with less spotty flow, and the grains pass through this grain tank. It is possible to provide sufficient humidification time by circulating multiple times, and it is also possible to avoid sudden excessive concentrated humidification and use a gentle and safe humidification conditioning effect, which prevents the humid air from blowing through. ,
A remarkable effect is that highly efficient tempering treatment that does not cause grain cracks is possible.

In particular, in the present invention, since the volume of the non-humidifying tempering device is reduced, the entire tempering device can be made compact, and the tempering time can also be shortened, resulting in energy savings.

In addition, the grains in the grain tank of the present invention are taken out of the tank and the moisture content is detected by an automatic moisture meter. When the grains are humidified and conditioned to the expected final moisture content, the humidifier and the blower are activated by the signal from the automatic moisture meter. In addition, if the temperature of the grain is extremely low during the cold season, hot air from the heater is sent to the humid air supply room as a preheating process to bring the grain to the appropriate temperature (e.g. 20℃). It is also possible to provide a thermometer that stops the heat transmission from the heater when this temperature is reached, and when the grain temperature drops during humidification, sends an appropriate amount of heat again to keep the grain at a nearly constant temperature at all times. Additionally, if the grain temperature is extremely low during the preheating process, an electric circuit for a thermometer connected to the electric circuit of the humidifier may be installed to stop humidification or moderately adjust the amount of humidification until the grain temperature reaches the standard temperature. be.
