1. A machine learning method for predictive maintenance of a dryer comprising:
- i) obtaining over a communication network, an information associated with the dryer, wherein the information comprises measurements of a current associated with at least one heater of a heater bank, wherein the heater bank is associated with the dryer;
determining a failure data associated with the at least one heater, wherein the failure data indicates one of a poorly functioning and a failed heater, wherein the failure data is determined through a comparison of ratio of three phase currents with a healthy heater using one of a split-core transformer type machine wearable current sensor or a Hall effect based current sensor associated with the at least one heater;
ii) receiving measurements of a vibration level of at least a process blower, a cassette motor and a regeneration blower associated with at least one dryer;
iii) determining an anomaly through at least one of a back pressure and a fault associated with at least one of the cassette motor and the regeneration blower, wherein the anomaly is determined based on at least one of a vibration and magnetic field through an IoT based method;
iv) tracking at least one of the vibration and the magnetic field of at least one of the process blower and the regeneration blower; and
v) raising an alarm for maintenance when an anomaly is at least one of a detected in a real-time and predicted for a future time, wherein the prediction is based on at least one of a machine learning algorithm or a look up table.

Abstract
A machine learning method and system for predictive maintenance of a dryer. The method includes obtaining over a communication network, an information associated with the dryer and receiving measurements of a vibration level of one of a process blower, a cassette motor and a regeneration blower associated with the dryer. Further, an anomaly is determined based on at least one of a back pressure and a fault and balance of at least one of the process blower and the regeneration blower is tracked. An alarm for maintenance is raised when one of an anomaly and an off-balance is detected.
