<p>Yes you can, but the whole point of hashing is to share the results with the blockchain which <em>can only be done while online</em>. Without sharing results there is a very big chance you are calculating the wrong transactions--transactions which have already been hashed by someone else.</p>

But can we mine on a offline computer carrying the results and needed information through a pendrive everyday?

<p>Is it possible to run a Bitcoin Miner offline and calculate hashes without being connected to the Internet?</p>

Yes you can, but the whole point of hashing is to share the results with the blockchain which *can only be done while online*. Without sharing results there is a very big chance you are calculating the wrong transactions--transactions which have already been hashed by someone else.
