1. A grain moisture regulating system comprising:

  • a grain bin having grain bin airflow means operative to force external air through grain stored within said grain bin;

    a fan for blowing outside ambient air into said grain bin in a path from beneath a grain mass stored within said grain bin, through said grain mass stored in said grain bin, and through an air outlet at the top of said grain bin;

    a humidistat fan control system which measures ambient moisture in the air outside said grain bin and compares it to ambient moisture in the air inside said grain bin for controlling said fan;

    a fan operation control system defined by a plurality of humidity sensors which measure ambient moisture in the air outside said grain bin along with measuring the moisture in the air above the grain mass within the grain bin to produce a signal for said humidistat fan control system;

    a computer which receives input signals from said fan operation control system, wherein a desired ambient moisture threshold level of said grain mass is set into said computer, and when the amount of ambient moisture in the air outside said grain bin exceeds said desired ambient moisture threshold level of said grain mass, said humidistat fan control system will turn said fan off, and prevent greater than the desired ambient moisture from blowing through said grain mass, and when the amount of ambient moisture in the air outside said grain bin is lower than said desired ambient moisture threshold level of said grain mass, said humidistat fan control system will turn said fan on, and allow drier air to blow through said grain mass; and

    a plurality of timers setable in timed increments for maintaining generally continuous power to said fan and further controlled by said computer for maintaining power to said fan as a function of said desired ambient moisture threshold level of said grain mass.
