The invention designs a compact automatic vending system integrating feeding, fermentation, baking and automatic vending into a whole aiming at bread for daily consumption. The system can realize baking and selling of bread, has compact structure, small volume and complete functions, and fills the gap of the current market. Disclosure of Invention The invention belongs to a mechanical structure innovation, which is characterized in that batch automatic feeding, material separation, production and storage are realized in a small-profile package automatic preparation vending machine by a simple structure. The bread machine has the advantages of simple and reliable structure, easy realization, and automatic preparation, storage and unmanned selling of bread in a smaller volume. The mechanical structure is composed of a lower storage and feeding system, an upper integrated material distribution system and a middle baking, storage and distribution system. The invention has the innovation point that the upper material feeding system and the middle baking system are organically combined, and the liquid and powder equal-part material distribution is realized by using fewer control systems. The full-automatic bread preparation and selling all-in-one machine (figure 1) is controlled by a PLC, and can perform feeding of about 10 batches in one day, complete fermentation of 10-15 breads in each batch, bake, store programs, and prepare 100-150 breads in one day in each program period of about 2 hours. The machine is provided with two sets of storage and feeding systems, namely flour storage and feeding and liquid storage and feeding. Flour for making bread is stored in a flour storage tank (1) at the lower part of the machine, a venturi powder pump (2) is arranged below the flour storage tank (1), the venturi powder pump (2) firstly conveys the flour to an integrated material separating plate (6), and the integrated material separating plate (6) divides the flour into 10-15 parts and conveys the flour to a baking system (7) at the lower part. The liquid required for bread baking (including water, yolk powder, milk powder, sugar, edible oil, butter, salt, etc.) is stored in a main tank (3). After flour is conveyed, a metering pump (for preparing 10-15 bread doses) quantitatively conveys the mixed liquid of the main liquid tank (3) into a liquid separating tank (4), and a yeast feeder (5) is arranged at the upper part of the liquid separating tank and automatically feeds yeast into the liquid separating tank. The mixed liquid added with the yeast is stirred and mixed in a liquid separating tank (4) and then is conveyed into an integrated material separating plate (6). The integrated material separating plate (6) is fixed and integrates the functions of liquid, powder and gas diversion. The integrated distributing plate (6) distributes flour and mixed liquid evenly into a baking mould of the baking system (7) successively. The baking system (7) comprises 10-15 cylindrical baking molds and 10-15 stirring motors, wherein the baking molds are fixed above a piece of strip-shaped aluminum alloy plate, the motors are fixed below the aluminum alloy plate, and the baking molds and the stirring motors are connected through a coupling. In addition, the baking mould is provided with a set of vertical lifting, a set of rotating and a set of heating system. After the flour and the mixed liquor are delivered into the bread baking mold, the PLC performs a stirring, fermenting, baking process. After the baking process is completed, the bread baking mould is turned over from 90 degrees vertically upwards to 60-80 degrees obliquely downwards, and the baked bread falls into a bevel chute (8) with 10-15 tracks by gravity and vibration. The bread is stored in a chute, and 10-15 cylinders or motors (9) at the tail end of the chute are used for controlling the shipment of the bread. After the consumer successfully completes the payment, the PLC performs the shipment procedure. In addition, th
