8. A method for producing premixed flour by uniformly mixing embedded yeast step by step comprises the following steps:
(1) According to different properties, the premixed flour production raw materials are divided into: yeast, oil auxiliary materials, protein auxiliary materials, emulsifying agents, other additives, starch auxiliary materials and flour main materials. (2) Firstly, adding the oil auxiliary materials into a temperature-controlled stirring and uniformly mixing mechanism, and controlling the temperature according to the characteristics of the selected oil auxiliary materials to enable the oil auxiliary materials to reach a corresponding liquid state close to solidification; the yeast is cooled to a temperature which is greatly lower than the solidification temperature of the oil auxiliary material at an ultralow temperature, and is slowly put into a temperature-control stirring and mixing mechanism, and is continuously stirred and mixed uniformly, the oil auxiliary material directly contacted with the yeast is crystallized by taking the yeast as a core, the yeast is embedded in the oil auxiliary material, and the viscosity of the oil auxiliary material is slightly increased due to a small amount of crystallization. Then adding proper amount of emulsifying agent and other additives into the protein auxiliary material in the state of protein solution, regulating the temperature to the same temperature as the oil auxiliary material, putting into a temperature-control stirring and uniformly mixing mechanism, continuously stirring and uniformly mixing to form an oil-in-water emulsion material, and embedding yeast into oil drops of departments. (4) And opening a material outlet switch to enable all liquid materials in an emulsified state to enter the temporary storage pumping mechanism below, closing the material outlet switch, mixing the next batch of materials in the temperature-control stirring and uniformly mixing mechanism, and circulating the above steps to enable the temporary storage pumping mechanism to always hold the materials. (5) The liquid material temporary storage pumping mechanism pumps liquid material to the liquid material atomizing mechanism, and is upwards sprayed into fog-like liquid drops through the atomizing nozzle under the action of compressed air to enter the constraint airflow hopper, protein and water outside the inner lipid layer of the liquid drops or only protein and water are contained in part of the inner lipid layer, and yeast is embedded in part of the inner lipid layer. The circulating air flow input ring forms stable air flow in the circulating air flow pipeline system, the starch auxiliary material enters the circulating air flow pipeline system through the starch feeding mechanism to circularly move, and the weight of the liquid drops is larger than that of starch granules of the starch auxiliary material. (6) The circulating air flow pushes the liquid drops with upward initial velocity to move upwards when passing through the bottom of the constraint air flow hopper, the pipe diameter of the constraint air flow hopper is gradually increased, the air flow velocity is gradually reduced, the liquid drops with larger weight are not supported to move upwards, starch grains collide with the liquid drops continuously in the process, the surface of the liquid drops can absorb starch grains in a viscous manner, the starch grains wrap the liquid drops gradually, the weight of the liquid drops continuously increases and then starts to descend, the constraint air flow ring on the pipe wall of the constraint air flow hopper sprays air flow to restrict the liquid drops to move upwards or downwards, and the wrapped liquid drops continuously collide with the starch grains after falling into the vertical section of the powder air flow circulating pipe and finally fall into the drying and mixing system. (7) The residual starch particles which are free from collision and have smaller weight continuously rise to enter the next section of channel, the pipe diameter of the air flow with starch auxiliary materials is suddenly increased after the air flow enters the air-material separation bin, the speed is reduced, the starch auxiliary materials are settled and accelerated, part of air is discharged through the filtering port above, and the air pressure in the circulating air flow pipeline system is regulated. The circulating air flow input ring at the bottom of the powder air flow circulating pipe circulating section provides further circulating air flow and prevents liquid drops from entering the circulating section. (8) The materials falling into the drying and mixing system are dried into auxiliary material particles through a drying section, wherein the auxiliary material particles are respectively a starch layer, a protein layer and a lipid inner core or the starch layer and the protein layer from outside to inside, part of the lipid inner core is embedded with yeast, and two layers of wall materials of lipid and protein are arranged between the yeast and the carbohydrate at intervals and are in a dormant state. The auxiliary material particles fall into a main material mixing mechanism and are uniformly mixed with the main material flour to form a premixed flour product. The user mixes the premixed flour product with water, then the embedded wall material is dissolved and broken, and the yeast is contacted with carbohydrate to start fermentation. The size of the auxiliary material particles and the proportion of each component can be adjusted by controlling parameters such as the proportion of each ingredient, the air flow speed, the spray droplet size and the like in the embedding spray system and the circulating air flow pipeline system.
