Sealing and Checking

The silo can be easily and comfortably sealed hermetically with tallow, soft soap, wax, and grease or by means of a rubber band or tape.

Before putting tablets into the silo, seal the seed outlet with its soldered interlocking joints facing upward.

After putting tablets into the silo, seal the intake throat with its soldered interlocking joints facing forward.

Checking for Leaks

Once tablets have been put on top of the grain, wait 3 to 5 hours before checking if gas fumes from the tablets are leaking.

If there is a leak of gas fumes, there will be a smell like that of garlic.

Cover the spot from which gas fumes are escaping with wax or soap, or call in an artisan to make the necessary repairs in case the leak is due to a manufacturing error.

Continue to check for leaks on a daily basis.

Fumigation Period

For fumigation to be effective the silo should be hermetically sealed, with no leaks that allow gas fumes to escape. The silo should be kept closed and tightly sealed for 10 days.

The grain is ready to be eaten 1 day after the fumigation period is over.

Keep the intake throat and seed outlet closed in order to prevent new insect infestations.

Periodical Checking

Check the grain both at the intake throat and at the seed outlet every 15 to 30 days.

If the grain contains moisture, remove it from the silo and expose it to the sun, as shown in step Drying and Cleaning.

If live insects are detected, you will have to fumigate again using the same recommended amount of tablets, based on silo capacity. Remember to seal both lids with tallow, soap, or grease for 10 days.
