DETAILED DESCRIPTION

[0013] Reference Figure 1-3 The specific embodiment includes a tank body 1, a nitrogen tank 2 is arranged outside the tank body 1, a first air supply pipe 3 is arranged in the middle of the bottom of the tank body 1, and a plurality of air outlet holes 6 are arranged on both sides of the first air supply pipe 3, two second air supply pipes 4 are symmetrically arranged on the edge of the bottom of the tank body 1, and a plurality of air outlet holes 6 are arranged on the top of the second air supply pipe 4, a third air supply pipe 5 is arranged above the first air supply pipe 3, and a plurality of air outlet holes 6 are arranged on the bottom of the third air supply pipe 5, and a circulating air path 7 is connected to both ends of the first air supply pipe 3, the second air supply pipe 4 and the third air supply pipe 5, and a A circulating air pump 8 and an exhaust valve 9, the air inlet ends of the first air supply pipe 3, the second air supply pipe 4 and the third air supply pipe 5 are respectively equipped with switch valves 10, the air outlet side of the circulating air pump 8 is provided with a gas filling pipe 11 connected to the nitrogen tank 2, the air outlet side of the circulating air pump 8 is provided with a heater 12, a guide frame 13 is provided between the first air supply pipe 3 and the third air supply pipe 5, and a plurality of guide plates 14 are symmetrically and obliquely provided on both sides of the guide frame 13, the inner end of the guide plate 14 is higher than the outer end, a gap is left between the two rows of guide plates 14, and a plurality of through holes 15 are provided on the guide plate 14.

[0014] The mixed raw material of milk and black rice is placed in the tank body 1, and nitrogen is injected into the tank body through the nitrogen tank 2. At the same time, the circulating air pump 8 and the exhaust valve 9 are turned on to gradually replace the air in the tank body 1. After the nitrogen content in the tank body 1 reaches the preset standard, the exhaust valve 9 is closed, and the heater 12 is turned on to heat the mixed raw material by heating the nitrogen. When the temperature in the tank body 1 reaches the preset standard, the first air supply pipe 3 and the second air supply pipe 4 are turned on, and the first air supply pipe 3 pushes the raw material at the bottom of the tank body 1 to the second air supply pipe 4, and the second air supply pipe 4 pushes the raw material upward, thereby forming a stirring process inside the tank body 1 that flows from the middle of the bottom to the bottom edge, then flows upward along the edge of the tank body 1, and finally flows back downward from the middle of the tank body 1. During the whole process, the nitrogen is dispersed in the raw material to achieve uniform heating of the raw material. During the fermentation process, the exhaust valve 9 and the gas pipe 11 are periodically opened to replace the gas inside the tank body 1 and maintain the anaerobic environment in the tank body 1. When entering the middle and late stages of fermentation, the viscosity of the raw material liquid increases, and the third air supply pipe 5 is opened to strengthen the stirring of the raw material liquid. The third air supply pipe 5 sprays nitrogen downward, driving the raw material and the guide plate 14 to produce relative movement. Under the guiding effect of the guide plate 14, the raw material gradually flows to both sides. The gap between the two rows of guide plates 14 and the through holes 15 on the guide plate 14 facilitate the two-way flow of nitrogen gas in the middle part of the tank body 1 (the third air supply pipe 5 sprays nitrogen downward, and at the same time, the sprayed nitrogen gradually decreases its downward movement speed under the action of buoyancy, and then turns to flow upward).

[0015] A filter 16 is provided on the air inlet side of the circulating air pump 8. The filter 16 is used to filter the moisture impurities contained in the nitrogen.

[0016] Bypass holes 17 connected to the air outlet holes 6 are provided on both sides of the air outlet holes 6 at the bottom of the third air supply pipe 5, and the angle between the bypass holes 17 and the air outlet holes 6 is 45 degrees. The bypass holes 17 can form a local lateral flow trend in the middle of the tank body 1, further improving the uniformity of stirring and heating of the fermented raw materials.
