Process for deodorization of recycled polyolefin pellets (23) in three steps: In a first step, the moist pellets (23) are contacted with a circulating inert gas at a temperature between 110° C. and 160° C. in a steam stripper (11), and the steam is precipitated in a condensate trap (29). In a second step, the pellets (23) are sent to a vacuum silo (13) under negative pressure and contacted with a gas flowing in countercurrent. In a third step, after the vacuum silo (13) the pellets (23) are sent to a first heat exchanger (15) and contacted with the gas flowing in countercurrent from the second step.
