I have a lot of extra produce. I would like to dehydrate them for later use. My dehydrator was not cleaned for pesach. It was never used for chametz mamash but has residue of kitnoyos on it. May I dehydrate the produce on it now
Yes you can. The reason is because you are doing it to avoid the loss of the produce, which is permitted on Chol Hamoed as it is considered a davar ha’aved. Regarding the kitnois aspect, if it wasn’t used within 24 hours and it is clean the kitnois issue is also alright, besides you are not using it on Pesach in any case.
