How do you do that? Just strip off the cob, vac bag, & freeze?
Blanch it, dunk it in cold ice water to stop the cooking.
Use a device like this to cut it off the cob.

Bag it in freezer bags then freeze.
Usually when we are done we take the left over juice and put it in the bags of corn with maybe a hair extra water. That way the corn isn't sitting dry in a bag. Try to get all the air out before you zip the bag up all the way.
Use a big turkey fryer to boil your ears, and a large storage tote full of cold water to cool them off. Then do your cutting in a roaster pan of some sort that way you can contain all the kernels and juice. Or a shallow sided tote works too.
