Tough canola

[katoe]

How tough can canola be stored with aeration if it goes in cold. Im not considering large bins just 2200 bu hoppers.Thanks

[Rareearth]

Or
Regardless of moisture level at what temperature does canola start to heat?

If it's at -5C can it heat?

[Ache4Acres]

From what I read canola that is +5C or less should store for the winter at basically any moisture level. I would think anything below -5c would not heat.

But boy oh boy I have learned never to say never

Ache.... I was just about to post that chart but was looking for one that went higher on the moisture scale. the line is going almost straight up at that point so maybe higher moisture wouldn't mean as much as the temperature it is going into storage at.... speaking of temperature, the heading on the bottom chart axis states "INITIAL" Seed Temperature. Holy crap.... can you get it "cooled" fast enough to prevent spoilage if it went into the bin at say 10-15 degrees? Most of the harvesting under these shit conditions would have happened during the heat(relative term) of the day..... Kinda scary!

Had a discussion going regarding this a little while ago.

Here is the chart I attached. Please note this is the maximum days before clumping. Other research has highlighted that higher oil content in today's canola has likely lowered these "safe storage" values.


I would be extremely careful relying on air bins with high moisture canola. Forecast temperatures for the next while will not be low enough to freeze a bin.
Taking some out and making sure there isn't a pile/cone on top would help.

18% canola in a 2500 bu flat bottom bin for 5 days, took it out today, it didn't heat but it came out in fist sized lumps that kept plugging the auger (we were taking it in to dry). This had a full areation floor under it with a 5HP inline fan running 24/7 since we started putting canola into the bin.


Very careful with high moisture canola.

[farmaholic]

Also notice how ambiguous the first chart is...... no mention of actual number of days because I assume there is no hard and fast rules as to how long it would take for the heating/spoilage to occur.

I would think moving it would also help.



Sorry 101 for double posting..... never knew you posted the same chart.

Only run fans while loading if you have a Lexion like Klause and no chaff in your sample. The chaff can blow down to the walls and create a pathway for air. Maybe its crap but I do not run fans while loading.

[farmaholic]

Biglentil.... I can see that being true but most of the chaff ends up against the wall anyway... nature of the beast.

We are about to find out the limits of tough grain after this year.

People bagging canola at 16 to 12 with intentions of running it though a dryer which isn't setup yet & or a crusher taking it within a few weeks. Or a 42000 bus bins at 12% with one 10hp low speed fan.

As the Mike Tyson once said "Everyone has a plan until you get punched in the face"

The road to Ritchie Bros was paved with good intentions.

Here's another chart from PAMI showing what a guy can expect for air drying based on temperature and RH.

Icy...some people around here have sacrificed their financial well being along with mental and physical health for their insatiable ego.

So much for so little....

This topic will be reoccurring all winter I'm thinking.

One positive with canola is that it flows out of the truck decent at 2x the dry mark unlike wheat which will be a challenge to flow.

Interesting chart 101

I guess that means that right now at 8C and 90% Humdity i am actually not drying my canola but adding moisture?

I have always felt that the drying front in a bin is at 100% moisture and turning off any fans except in a heavy rain is counter productive. Need to keep that moisture layer on the move.

[farming101]

If RH is 90% 24 hours a day it is doubtful any drying will take place with unheated air. There must be some part of the day with lower RH for natural air to work. A little supplemental heat can keep the process going, but need to keep air flow rates up.
