step 202: selecting black beans with the production place of northern Shaanxi as raw materials.
In practical application, high-quality black beans produced by loess of Shaanxi province are selected as raw materials, the high-quality black beans are screened, subjected to stone removal and impurity removal, stored in a ventilation and drying environment, the moisture content is kept to be less than or equal to 14%, and the black beans are free of mildew and insect damage.
Step 204: and (3) carrying out peeling, bean soaking and pulping on the black beans to obtain the bean paste.
In practical application, when black beans are peeled, the black bean skins and the skin surfaces are removed by using a peeling machine to obtain the soybean milk, so that the soybean milk is clean and has no bean skin residues. The actually obtained soy bean is about 85% of the mass of black beans.
When the soya bean milk is soaked, elm yang spring water or clean water without impurities is introduced according to the following ratio: the soybean is soaked in the soybean according to the proportion of 100 to 15, the water temperature is controlled to be 20 to 25 ℃, the soybean is soaked for 6 to 8 hours in summer, and the soybean is soaked for 8 to 10 hours in winter. Until the soaked bean curd is full, moderate in hardness and slightly elastic, the nail can be cut, and the soaked water is clear and not turbid, so that the soaked high-quality bean curd is obtained.
Grinding the soaked bean curd with soaking water to obtain bean curd, wherein the bean curd is uniform in water ratio, properly adding water to clear the chamber, colloid-grinding for two to three times, and crushing the bean curd into bean curd, so that the bean curd is fine like mud, proper in thickness, not coarse and not bad, uniform in color, free of particle bodies and free of granular sensation.
Step 206: and carrying out pulp-residue separation on the soybean paste to obtain the soybean milk.
In practical application, the soybean paste can be subjected to centrifugal filtration or filter pressing by using a sieve with 80-100 meshes, so that the soybean milk is separated from the soybean dregs, water is properly controlled until the soybean milk does not wrap the dregs and the dregs do not drip, wherein the filter bag or the sieve is cleaned in time and kept clean, and filter residues are removed.
Step 208: and (3) performing boiling, curdling and coagulating, and jellied bean curd treatment on the soybean milk to obtain the tofu pudding gel.

The weight of the soybean milk is uniform, the concentration of the soybean milk is adjusted to be about 8.5 degrees of Baume degree, and the soybean milk is boiled to reach the temperature of 97-100 ℃. The soybean milk is boiled quickly and in short time, the boiling time is controlled within 15 minutes generally, and the boiling time is controlled to be three times and three falls to eliminate floating foam, the boiling soybean milk is taken out of a pot in time, the soybean milk is not taken out while raw soybean milk is mixed, the mixed raw soybean milk is easy to deteriorate, and the soybean milk is not turned into bean curd. Curdling and coagulating the boiled soybean milk, standing the curdled soybean milk for 20-25 minutes, allowing a large amount of soybean milk gel to gather after curdled soybean milk, draining off the soybean milk successively, using a spoon to core the curd while curdled soybean milk, the beancurd jelly aggregates with stable and fresh tissue structure, white and moist color, uniform package pulp and sufficient beany flavor are formed to the maximum extent, the temperature of the squatting pan is controlled to be between 30 and 60 ℃, and a large amount of juice overflows.
Step 210: and filling the beancurd jelly gel into a mold, and pressing and desizing to obtain the finished product beancurd.
In practical application, the beancurd jelly gel obtained after the jellied bean curd is squatted is subjected to die filling, a pressure top or a pressure stone is adopted to extrude a slurry draining template after the die filling, and the slurry is removed and formed to obtain the finished product beancurd.
Step 212: and cutting the finished bean curd into blocks.
In the embodiment of the specification, a special dicing machine can be adopted to dice the bean curd to obtain the bean curd blocks with uniform size and complete dicing. In practical applications, the used bean curd may be made by itself or obtained from external sources, and is not particularly limited herein.
