The TGM System includes four policies that can be selected for automatic operation of fans to achieve specific goals. These are fully programmed. They do not require programing for start and stop times or conditions. You merely select the policy (mode) that fits your circumstances best. Most storage needs are met with Maintain.

Additionally Cery™ will become available to manage fan operation. To begin with it will select the best of the four policies and switch among them automatically as factors change. Later it will enhance decisions with additional information automatically.

In time (1-3 seasons) Cery will guide and manage fill rates of higher moisture grain. Cery needs to learn your operation first. Once up to speed it can guide whether to add another load or to wait. It will optimize fan run times. It can also manage the addition of a limited amount of heat  without causing roof condensation.

Cery™

Cery is an intelligent helper that learns your set up and practices over time. It is not operational for a new installation. It  can be activated after a normal season — longer if the learning process is interrupted. After sufficient time to learn Cery will select an optimum fan policy that is adjusted by season, weather, delivery date, electricity cost, Smart Grid state and history, market price changes, transportation disruptions and other factors. It uses predictive analytics to inform you of progress in a bin — MC change for example — and also estimated time to completion. It becomes more useful (smarter) with additional seasons of experience.

Maintain

Maintain is the most intelligent setting (without Cery) that includes adaptiveness to adjust to changing weather. Most storage situations are best solved with this setting. This setting will adjust to seasonal changes and should be used for longer (more than 1 month) term storage.

This setting will move your grain toward your MC target over time so the entire mass will become uniform in temperature and MC. It does not matter whether the grain is wetter or dryer than your target, nor does it matter that there are layers of each.

Dry

Dry is a setting that will run any time ambient conditions are dryer than a MC setting. Temperature and EMC limits can also be set. Dry is not for long term storage, rather short term conditioning needs.

Dry can be useful for natural air drying bins especially if they are remote. In late season this policy can capture run times that otherwise would be missed.

Rewet

Rewet is a setting that will run any time ambient conditions are wetter than a MC setting. Temperature and EMC limits can also be set. Rewet is not for long term storage, rather short term conditioning needs. It will add more moisture to a bin faster than Maintain but will not achieve the uniformity of Maintain.

Leaving a bin set to Rewet can over wet the grain. There is little concern over bursting a bin because of the air space around grain (approximately 33% for soybeans and 40% for corn). The seeds do expand but into the airspace.

Finish

Finish is a setting that operates similar to Maintain except there is not adaptiveness to the weather. It should not be used for long term storage but can be useful in certain conditioning situations, especially if high air flow rates are available. Normally Finish will be used before shipping to achieve more precise MC levels for high value crops.
