Embodiment
[0046] The ambient temperature is 12°C, and the amount of grain in the tower is 8 grids. At this time, the upper value of the temperature range in the set temperature lookup table is 15°C (43) and the lower value is 10°C (40). According to the formula: Lookup table temperature = (( The upper value of the temperature range in the table - the lower value of the temperature range in the table) / 5) × (ambient temperature - the lower value of the temperature range in the table) + the lower value of the temperature range in the table) to calculate the drying temperature = ((43-40) / 5) ×(12-10)+40 = 41.2°C

The invention discloses a grain drying machine which comprises a series of drying towers controlled by control units and a system upper computer, and is characterized in that the system upper computer is respectively connected with the control unit of each drying tower by virtue of a control circuit; an online moisture content detector and a temperature sensing device are connected to the control unit; and the online moisture content detector and the temperature sensing device are arranged in the drying tower. The grain drying machine disclosed by the invention has the advantages that the operation is easy and convenient, the drying air temperature is accurate to set, and the drying effect is good.
Description
technical field [0001] The invention relates to a grain processing device, in particular to a grain dryer and a control method thereof. Background technique [0002] The method of passing the wind at a certain temperature through the grain to dry the grain to reach the target moisture is widely used in grain dryer equipment. [0003] The grain dryers in the prior art rely on manual experience to set the air temperature during drying, and observe the quality and moisture changes of the grain during the drying process to correct the set drying air temperature. There are multiple correction adjustments to get the proper set temperature. Inexperienced operators may not have adjusted to the best drying setting air temperature. Low temperature will result in low drying efficiency, and high temperature will cause grain quality to decline (rice cracks, low seed germination rate, etc.). [0004] Therefore, how to control the dryer to set the optimum drying air temperature is a tech...
