Abstract
A system of grain drying in a specially constructed bin which involves electronic readings of multiple parameters and control of the operation of high volume blowers by a programable control system which reacts to the parameters. Sensors read ambient air humidity and temperature and grain temperature at various locations in the grain bin. These readings are combined with grain moisture readings secured through sampling ports to control the air flow based on a preset goal for moisture level of the grain. Various parameters are also displayed for operator information.
Claims19
An automatic grain drying system comprising:
- a grain storage container;
- a blower moving air from outside the storage container through grain located within the storage container;
- a control system which monitors temperature and moisture of grain within the storage container and temperature and moisture of air outside the storage container and automatically operates the blower or blocks operation of the blower depending upon the relationship of the temperature and moisture of the stored grain to the temperature and moisture of the outside air;
- and
- timer means selectively actuatable manually by an operator to operate the blower manually, without influence by the temperature and moisture levels of the grain and air, for a specific period of time, and then operable automatically after said specific time period to return the system to automatic control.
An automatic grain drying system comprising:
- a grain storage container;
- a blower moving air from outside the storage container through grain located within the storage container;
- first means for monitoring and taking readings of grain temperatures at several locations within the storage container;
- second means for monitoring and taking a reading of air temperature outside of the storage container;
- third means for monitoring and taking readings of grain moisture levels at several locations within the storage container;
- fourth means for monitoring and taking a reading of air moisture level outside of the storage container;
- and
- a control system which receives said temperature and moisture level readings from said first, second, third and fourth means and operates the blower or blocks operation of the blower depending upon the relationship of the temperature and moisture levels of the grain at the several locations within the storage container to the temperature and moisture level of the air outside of the storage container.
