The invention discloses a
palm fruit yeast killing technology. The technology comprises the following steps: 1, feeding a material from a material inlet; 2, opening a movable turnover plate after completing the first material feeding to enable the material to fall into a tank under the movable turnover plate, continuously feeding the material from the material inlet, and closing the movable turnover plate after completing the second material feeding; 3, continuously feeding the material from the material inlet, and closing the fast opening door of the material inlet after completing the third material feeding; 4, letting steam in the tank until the pressure reaches 0.05-0.35MPa and the temperature reaches 120-350DEG C, and waiting for 3-30min; 5, opening a steam
discharge valve, waiting for 3-30min, closing the steam
discharge valve, and repeatedly step 4 until
yeast killing requirements are reached; 6, opening the steam
discharge valve, waiting until the pressure in the tank returns to zero, opening a
water discharge valve, and waiting until a deposition liquid in the lower part of the tank is evacuated; and 7, sequentially opening the fast opening
doors of material outlets and the movable turnover plate, and closing the movable turnover plate after completing the first material discharge and the second material discharge. According to the technology, the material feeding and the material discharge are carried out in a grading and batch mode, so material bridging and
caking are avoided, material unloading is convenient, and destructive
impact of the material to the bottom of the tank is prevented.
