The "Cleaning the Cleaner" Protocol: Avoiding Cross-Contamination Between Organic and Non-Organic Runs

If you run a "split operation"—growing both organic and traditional crops—you know that the harvest isn't the only busy time. The time spent cleaning your equipment is just as critical. For an organic farmer, one stray kernel of treated or GMO seed can put an entire year’s certification at risk.

The biggest "Organic Control Point" on many farms is the seed cleaner. If you use the same machine for both types of grain, you need a bulletproof protocol to satisfy your inspector. Here is how to "clean the cleaner" effectively and keep your records straight for 2026.

Cleaning out a Farmstead seed cleaner for organic grain certification

1. The Power of "Dry Cleaning"
Because Farmstead cleaners are built with an open, accessible design, they are much easier to clean than massive industrial units. You don't need harsh chemicals; you need physical removal.

• Vacuum and Blow: Use a high-powered shop vac and compressed air to clear out every nook, cranny, and corner of the hopper and the screen decks.
• The "Visual Check": Organic inspectors want to see that the machine is "visibly clean." Pay close attention to the seals and the discharge chutes where "hang-up" grain usually hides.

2. The "Purge" Batch
Even with the best vacuuming, there’s always a chance a single seed is tucked away. The standard organic protocol is to run a Purge Batch.

• How it works: Run a small amount of your organic grain through the machine first.
• The Result: This "first flush" pushes out any lingering traditional seeds.
• Important: This purge grain cannot be sold as organic. Most farmers feed it to their own livestock or sell it as traditional "cleanings."

3. Record Keeping: The Paperwork Your Inspector Wants
An inspector doesn't just want to hear that you cleaned the machine; they want to see the log. Your Equipment Cleaning Log should include:

• The Date and Time of the clean-out.
• The method used (e.g., "Vacuumed, compressed air, and 5-bushel wheat purge").
• The name of the person who performed the cleaning.

4. Why the 150HD and 300HD Make it Easier
Traditional "legacy" cleaners often have hidden internal chambers that are nearly impossible to reach without a full teardown. We designed the Farmstead 150HD and 300HD with the family farmer in mind.

• Easy Screen Removal: You can pull the screens in seconds to get a clear view of the entire flow path.
• Open Discharge: There are no "blind spots" where grain can sit and rot or contaminate your next batch.
