Coffee bean wall breaking device

A coffee bean wall breaking device comprises a reactor, the reactor is internally provided with a raw bean processing space, the reactor is provided with an air inlet and an air outlet, and the air inlet and the air outlet are both communicated with the raw bean processing space; the carbon dioxide source is connected with the gas inlet of the reactor through a gas inlet pipe; the pump is arrangedon the air inlet pipe; the heating element is annularly arranged on the outer peripheral surface of the reactor; wherein the raw bean processing space has a volume, the exhaust port has an opening area, and the opening area of the exhaust port is 0.25-32.5 cm < 2 > per liter of the volume of the raw bean processing space. The coffee bean wall breaking device is used for carrying out wall breakingtreatment on the raw beans, so that the problem that chlorogenic acid in the raw beans is damaged by high temperature of baking treatment during subsequent baking treatment can be prevented. 一种咖啡豆破壁装置，包括：一个反应器，该反应器内部具有一个生豆处理空
