Abstract

DC60 (20/09/43) Rotary Grain Dryer With control (39), where the process fills Include whole grains Will cause the first hot air generator (20) to be activated and the second hot air generator (32) deactivated, and by the measured value Of the humidity of the air outside the detector The humidity of the outside air (38) will cause the air flow regulator (34) to work to change. Volume of air flow By ventilating (30) at the drying process, the regulator (39) also regulates hot air at one (20) and regulates the temperature of the hot air that is fed into each heating pipe (18) according to the Measurements of the water content of the grains And temperature control Of the hot air delivered during drying (13) according to the measured values of the water content of the grains and the amount of grains added Revolving Grain Dryer With control (39), where the process fills Include whole grains Will cause the first hot air generator (20) to be activated and the second hot air generator (32) deactivated, and by the measured value Of the humidity of the air outside the detector The humidity of the outside air (38) will cause the air flow regulator (34) to work to change.

Claims (4)

1.Rotary cereal grain dryer Where it contains: when heating To heat the grains With a number of heating pipes It is used as a passage of hot air from the first hot air-generating path when drying underneath it during such heating. To dry the grains by passing hot air received through each heating pipe along with the hot air. Two ways to generate hot air To suck hot air Of the drying time and the hot air is vented outside the dryer; When controlling the flow of ventilation air To control the amount of ventilation air Such ventilation paths; Method for measuring the humidity of outside air To measure the humidity of the outside air; And control paths that are electrically connected to each one of the hot air generation The way of air generation Such a second hot When controlling the flow of ventilation air And the outside air humidity measurement method Such a way of control During the addition of cereal grains, the first hot air pathway is activated at the same time. The Way of Hot Air Second such The work is stopped and the air flow control phase operates according to the measured outside air humidity value. This was measured by the outside air humidity sensing path and changing the ventilation air flow of the said ventilation path. 2. Revolving cereal grain dryer As described in claim 1, where the air flow of such drying time During the drying process When the flow of Ventilation is not controlled. By the time controlling the flow of ventilation air Is used as an analogy, and if the humidity of the outside air is higher than the humidity As defined, the drying air flow is Will be made into the first air flow Which is less than the equivalent Nearby And if the humidity of the outside air is lower than the set value Air flow in When drying it. Will be made into the second air flow Which is still less than the air flow That one And by the operation of the aforementioned ventilation air flow control phase, the ventilation air flow of the said ventilation path Changed 3.Grain dryer Circular as stated in Claim 2, where the required humidity value is 70%. 4.Rotary cereal dryer Where it contains: when heating To heat the grains With a number of heating pipes It is used as a passage of hot air from the first hot air-generating path when drying underneath it during such heating. To dry the grains by delivering hot air flowing through each heating pipe. With hot weather From hot air generation paths, ventilation routes To suck the hot air of the drying section and vent the hot air to the outside of the dryer; Method for measuring the temperature of hot air drying To measure the temperature of the hot air Sent to the drying process Method for measuring hot air temperature Of heating pipes To measure the temperature Of the hot air sent to the heating pipe Pathway for measuring water sections To measure the water content of grains; The chapter of input to put the amount of grain input into it; And the way of control Connected electrically to the route, one such hot air was generated. The second hot air generation path, the hot air drying air temperature probe, the hot air heating pipe, the hot air heating pipe. Measurement path That part of the water And at the aforementioned input Each path; Such a way of control During the drying process, control the route to One such hot weather To change the temperature of the hot air sent into the heating pipe Heat each pipe according to the measured value Of the water portion of the grains And a second hot air pathway to change the temperature of the hot air It was sent in the drying process according to the measured value of the water portion of the grains. And the value of the amount of grains that are put in
