If the calcium chloride is already anhydrous (as shown by the amount of water, $\ce{H2O}$, by weight percent), i.e. has little water, then there's nothing to do but package it in a manner that when it liquefies from absorbing water from the air, it won't drip on containers below. For an example, with a plastic box or pail below.
If there is substantial moisture alerady in the desiccant, then you'd need to dry it by heat (or find another source of calcium chloride).
Be careful pouring it into bags, as that generates irritating, though not poisonous, dust. Use a respirator mask and goggles if working with large amounts.
