West Central Indiana | I have spent a lot of time the last year googling discussions about grain dryers. Seems every discussion the last 10 years on here says to get a mixed flow (Screenless) dryer and don’t consider anything else. I currently have a farm fans continuous flow dryer that I have run in full heat mode 80% of the time since 1996. Just this last summer I put up a new dry leg because I was frustrated with my 5” air system being a bottleneck.
Now I’m thinking about a bigger dryer. I would like to go away from full heat drying and go to heat/cool....and was thinking vacuum cooling with a tower dryer. Been talking to 2 different salesman and neither one really wants to put a tower dryer in. One says I need a Grainhandler and not to even entertain a tower dryer. He says vacuum cooling and gas savings is overrated. The other salesman would like to sell me a double stack GSI dryer so I can pressure cool with the bottom fan. He says the double stack is a more versatile dryer in the event I have a lot of 17% corn I want to dry or for soybeans/wheat.
Anyone that has any experience with pressure cool vs vacuum and gas savings feel free to chime in here!
Thanks. | |
