I am not sure why this happens, but, playing ATM6Sky, 1.0.5, ExCompressum_1.16.5-4.0.2.jar on Forge 36.1.2, when feeding the auto-sieves with a sandwich from Culinary Construct, it permanently doubles the speed on the sieve, regardless of quality of the culinary construct, which means, unless broken and replaced, it can never be fed again.

I just thought it was an interesting interaction that you might want to know about.
