Bold statements and questions. As a dryer operators ourselves, we feel we can possibly push our relationship by asking these questions and making you question your knowledge of how a dryer work. Drying grain is a time consuming and often forgotten ‘art’ of averages at a very busy time of year.
Sadly the reality is that most computer programmers are not very good grain dryer operators and do not fully understand the interactions between reality and the theory of grain drying. Combine this with the need to work closely with and understand the law of averages, as well as, deal with speed and time demands on a modern farm. It is easy to see why embedded computer controllers are woefully incapable of drying grain, or that some manufacturers simply have not bothered.
Our experience led us to believe that most, if not all, continuous dryer manufacturers have made fundamental errors in their embedded controller computations. Talking with other dryer operators it seems no continuous dryer seems to have a very well written controlling system. As dryer operators and farmers we could get no one to listen to our concerns, needs and solutions. So we decided to develop our own solution. The Field Track - Dryer Control. In truth no development is ever finished, however the Field Track - Dryer Control successfully runs our dryer system as we expected it to do and far better than any other dryer controller we are aware of. All using simple logic, with a little dryer operator know-how and at no time using observational tables with which to make a control decision.
In developing our program and listening to other operators with a variety of continuous dryers, it became obvious that for some reason programmers had made some basic errors in understanding what is at play within a dryer. Some had even compromised the basic theory, which resulted is a failure to actually dry grain. It has been an interesting exercise learning and developing the Field Track - Dryer Control.
Most continuous dryer operators will be aware of the time required to maintain the efficient operation of a continuous dryer. This time is extremely expensive and wasteful when you consider that the calculation to monitor the grain and operate the dryer is quite simple, yet missed, or ignored by all the continuous dryer, and even some third party, controllers we have seen.
The variables at play within your continuous dryer are truly staggering. As a dryer operator you are probably blissfully unaware of the maths your sub-conscience has to deal with that makes your skill quite rare. It would be nice to think a computer could do the same, however sadly it cannot. If a computer had control of all of the variables then it might be possible, however some variables are simply not in the realms of control. With limited control people seem to have looked high and low for the answer and have either given up, or made things too complex and butchered the underlying theory.
- Grain Moisture.
- Burner Temperature.
- Air Bleed.
- Discharge Speed.
- Grain Movement Speed.
- Soft/Hard Grain.
- Grain Variety.
- Grain Temperature.
The Field Track - Dryer Control was created not as a single-button solution to an extremely complex problem but to present the dryer operator with the correct drying theory, in a package that would take the operators’ knowledge and drive the dryer to the operators’ demands and requirements, regardless of the input moisture. The result is a more efficient, faster and less time demanding dryer - the dryer you always wanted!
