The flour-mixing machine mainly uniformly mixes flour and water, the traditional industrial flour-mixing machine is generally horizontal and comprises a stirring cylinder, a stirring hook, a transmission device, an electric appliance box, a machine base and other components, the spiral stirring hook is driven by the transmission device to rotate in the stirring cylinder, and meanwhile, the stirring cylinder rotates at a constant speed under the driving of the transmission device. The flour in the jar is continuously pushed, pulled, kneaded, pressed, fully stirred and rapidly mixed, so that the dry flour obtains uniform hydration, and gluten is expanded to form dough with certain elasticity, elasticity and uniform flow. Because the gluten needs to form gradually, flour and water must stir certain time under sealed environment, this time is 10 minutes more than short, half an hour if long for the later order has longer latency to the use of dough, the feed is discontinuous, and the flour quantity of once stirring is great, collude and the agitator tank to the stirring of flour-mixing machine and all proposed higher requirement, the dough that forms after the stirring is great, also need accomplish processing in shorter time, higher requirement has also been proposed to the technology of later order.

Disclosure of Invention

The invention provides a sectional dough kneading machine, which aims at solving the problems of discontinuous feeding, long waiting time, high requirement on equipment, high requirement on the subsequent dough processing technology and the like of the dough kneading machine in the prior art. Kneading dough by matching the feeding auger and the dough kneading main body, mixing flour with water in the feeding auger to form wet paste, then feeding the wet paste into the dough kneading main body for stirring to form a dough shape until the stirring is finished; because one feeding auger assembly corresponds to more than two dough kneading main bodies, different dough kneading main bodies can be fed in a staggered mode, dough forming time in the dough kneading main bodies is staggered, and waiting time of a subsequent process is reduced; and because the dough kneading machine is divided into two dough kneading main bodies for kneading dough, the stirring load of the single dough kneading main body is reduced, so that the impact action of the dough on the stirring head and the cylinder body in the dough kneading process is reduced, and the service life of the equipment is prolonged.

The dough can be subjected to a wet mushy stage formed by mixing raw materials, a gluten forming starting stage, a gluten expanding stage and a gluten complete forming stage in the stirring process. In the gluten formation starting stage, the gluten expansion stage and the gluten complete formation stage, the dough is already formed into a dough shape, and the dough is not convenient to transfer between two containers, so that the dough needs to be transferred at the early stage of the gluten formation starting stage before the completion of the wet lake stage.

In the wet pasty stage, water is mixed with flour, and the flour begins to absorb water, so that water mainly stays on the surface of the flour to form wet pasty state, and the flour is not agglomerated in the wet pasty stage and has strong fluidity.

At the beginning of gluten forming stage, the flour finishes absorbing moisture, and starts to be connected with flour particles, and forms gluten with a net structure under the stirring action of the stirring head, the flour particles begin to stick to the cylinder due to the mutual binding force, but the gluten with the net structure is not too much, and the elasticity and the ductility are still poor.

Gluten expansion phase, which is the process by which gluten is further formed, the dough is also formed into a complex and numerous network from a simple and small number of networks, the surface of the dough begins to dry out, but the elasticity and extensibility are significantly improved.

The gluten completely forms the stage, and the network structure of the gluten tends to be stable and balanced, no matter from the quantity or from the complexity of the network structure, the gluten can not change greatly along with the stirring, the dough has good extensibility and elasticity, and the uniform gluten film can be pulled out.

According to the physical states of four different stages of forming gluten by flour and flour, the method is correspondingly improved in the aspects of sectional stirring, sectional water supply and continuous cooling so as to reduce the requirements of dough kneading process on the quality of equipment, improve the quality of obtained dough and reduce the waiting time of subsequent processes.
