An evaporator-reverser for easy cleaning internal and external tanks deposits. The system helps prepare maple syrup by keeping the bottom of the tanks clean and preventing the deposit of precipitates that cut heat transfer. Passage in the tanks is done by alternating tank 1 to tank 2 so that the diluted sap washes the bottom of a tank that is already filled with thickened sap and then the process is reversed. For this purpose a pipe is provided as well as control valves for the inversion.
Un évaporateur-inverseur permettant de nettoyer facilement les cuves des dépôts à la fois internes et externes. Le système aide à la préparation du sirop d'érable en gardant le fond des cuves propres et en empêchant le dépôt de précipités qui coupent le transfert de chaleur. Le passage dans les cuves se fait en alternance de la cuve 1 à la cuve 2 de façon à ce que la sève diluée lave le fond d'une cuve déjà garnie de sève épaissie et par la suite on inverse le processus. A ces fins une tuyauterie est fournie de même que des vannes de contrôle permettant l'inversion.
