System for real-time grain moisture measurement in mechanical static-layer dryers Sistema para la medición de humedad de granos en tiempo real en secadores mecánicos de capa estática

Device to measure the humidity average of a sample of coffee fruits during the process of drying in a dryer, in where this device this made up of (but not limited a): two concentric containers, one internal one, the other external one, where both containers have in their inferior end a perforated cover, and where the sample of coffee fruits lodges in the internal container; average which they allow to measure the variations of weight of the sample of lodged fruits of coffee in the internal container, and they generate a proportional signal to the weight. The device of the Vindication 1, that additionally contains an element that proportional convert a signal to the weight generated by the means that measure the variation of weight of the sample of fruits of coffee in a representative value of the humidity average of the sample of coffee fruits. The device of the Vindication 1 or 2, that additionally has means that take the proportional signal to the measured weight from the sample of the coffee fruits to generate an alarm signal when this humidity reaches a pre-established value at the same time suspending the fuel flow of the dryer. The device of the Vindication 1 or 2, that additionally has means that take the signal turned to the representative value from the humidity average of the sample of coffee fruits to generate an alarm signal when this humidity reaches a pre-established value at the same time suspending the fuel flow of the dryer. The device of vindication 1, characterized so that the means that allow to measure the variations of the weight of the sample of coffee fruits are a cell of load.
