Storing Carrots

Hi,

I'm looking to clear out my plot so I would like to remove the 2 rows of carrots I still have.  Whats the best way to preserve them please?

Can this be any horticultural silver sand?

when our carrot crop failed we went out and bought a net of carrots it took me a day to peel them and then wife blanched and put them in the freezer

For this purpose next year I was thinking of using small stackable plastic fruit & veg trays our local Polish Deli throw out, about 24x18" and 2-3 inches high, lined with cardboard then filled with sand or compost. Like these:

Would this work if they were then stored in a shed? Also could any root veg be stored this way?

I posted about a sand clamp in 8doubles' question about parsnips... dry sand was the key.
