The buffer plate can achieve the effect of elastic buffering to avoid being damaged during the feeding process, and realize the lossless fall of the square tofu onto the chain plate. When the buffer plate is in a free state, the distance between the lower end of the upper buffer plate and the lower buffer plate is greater than the maximum thickness of the square tofu.

Stir-fry until the moisture content of the gray tofu fruit is lower than the first set value (the stir-frying time is generally 30-40 minutes). Automatic stir-frying reduces labor intensity and improves stir-frying uniformity. Moreover, slow stir-frying will not damage the gray tofu fruit. The L-shaped arc plate maintains a gap close to the inner surface of the stir-fry pot, which can ensure that the gray tofu fruit can be easily turned over during the stir-frying process. The stir-frying mechanism is driven by a cylinder to lift and put into the stir-fry pot, which is easy to operate and convenient for taking the gray tofu fruit.

After drying, the surface of the tofu is gray, and the surface of the tofu is hard and has strong hardness. It is not easy to deform when pinched by hand, and it has a faint fragrance. When it is cut open, the internal structure can be observed to be pores of different sizes. After wiping off the ash on the surface, the golden color of the gray tofu can be seen.

[0023] Example 2: A method for making an ash tofu fruit making device is as follows: the baked tofu is sent into a tofu forming mold for tofu forming, and the tofu is formed into tofu blocks with a thickness of 3-5 cm. After being squeezed into place during the forming process, it is kept for a set time to gradually form. After the forming frame is removed, the formed tofu blocks are sent together with the forming bottom plate into a tofu cutting and pushing mechanism for cutting, and are cut into 3-5 cm tofu cubes. The cut tofu cubes are blocked away from the discharge end by a cutting knife, and the left and right front and back moving platforms are controlled to move, and the tofu cubes are gradually pushed into the feed port of the tofu ash-coated preheating device. Before the tofu cubes enter, tung shell ash is first added by the ash adding mechanism, and the firewood ash will accumulate on the buffer plate. When the buffer plate is completely accumulated with tung shell ash, they are gradually sent into the feed port set on the right side of the tofu ash-coated preheating device in a row. The tofu is coated with ash under the action of the buffer plate, and finally falls into the conveyor plate chain. The tofu cubes are transported upwards, transported in the ash coating chamber and continued to be sprayed with the set tung shell ash on the top, the temperature in the ash coating chamber is controlled at 40-45 degrees, and enter the first preheating chamber for transportation. The length of the first preheating chamber is 1m, and the temperature in the preheating chamber is controlled at 45-55 degrees. They are continued to be transported to the second preheating chamber, and the temperature of the second preheating chamber is controlled at 55-65 degrees. Finally, the preheated ash-coated tofu cubes are sent to the stir-fry pot, and tung shell ash is added according to the weight ratio of ash tofu fruit and tung shell ash of 1:1. The stir-fry motor speed is controlled at 20 rpm for stir-frying, and the stir-frying temperature is 120 degrees. Stir-fry until the moisture content of the ash tofu fruit is lower than the first set value (the stir-frying time is generally 30-40 minutes), stop stir-frying and take out the ash tofu fruit and send it to the baking device for baking. The baking temperature is 60-80 degrees. Bake until the moisture content is lower than the second set value (the second set value is less than the first set value, and the second set value is 10%).
