An inspection warrant shall be effective for the time specified therein, but not for a period of more than 14 days, unless extended or renewed by the judge who signed and issued the original warrant, upon satisfying himself that such extension or renewal is in the public interest. Such inspection warrant must be executed and returned to the judge by whom it was issued within the time specified in the warrant or within the extended or renewed time. After the expiration of such time, the warrant, unless executed, is void.
