A machine for producing ice-cream and the like including an outer boxlike housing, a processing tank that extends into the boxlike housing, and a discharge manifold which branches from the bottom of the processing tank to reach the boxlike housing at a front wall of the latter, and is structured so as to allow a product contained in the processing tank to flow out of the machine. The discharge manifold includes a tubular duct which protrudes from the bottom of the processing tank and ends with a mouth assembly which through-engages an appropriate opening obtained on the front wall of the boxlike housing. The mouth assembly includes a central sleeve that is rigidly and fixedly attached to the tubular duct.
