The invention discloses an automatic temperature control de-astringency method of persimmons, which can adjust gas. A closed space provided with a gas inlet and an exhaust outlet is built, carbon dioxide gas with the concentration between 80 and 95 percent is filled into the space, the temperature in the closed space is heated up and kept between 19 and 24 DEG C and after 36 to 48 hours, the de-astringency process is finished. The method has the advantages that 1. de-astringency time is shortened and total de-astringency can be realized for 36 to 48 hours; 2. the color of the persimmons is bright after de-astringency, the flesh has no change, when the persimmons are in the stage of hardness and brittleness, the persimmons can be kept for 7 days under room temperature and for 40 days under the condition of 0 DEG C, thus effectively prolonging shelf life; 3. mass production can be carried out and 20 to 40 tons of persimmons can be deastringent at a time.
