1. A coolant state estimation system that estimates a temporal change of a state of a coolant used in a processing machine, the coolant state estimation system comprising:
a coolant state acquisition unit that acquires a measurement value regarding the state of the coolant as measurement information in which the measurement value is associated with measurement time at which the measurement value is measured;
a processing information acquisition unit that acquires processing information on a processing condition of the processing machine; and
an estimation unit that estimate a temporal change of the measurement value after the measurement time of the measurement information using a learned model based on the measurement information and the processing information, wherein the learned model is a model that has learned the temporal change of the measurement value using teacher data created from the measurement information and the processing information.
