Technical Field

The invention belongs to the field of fermented wheaten food production equipment, and particularly relates to a double-cylinder circulating dough kneading and leavening integrated device suitable for factory continuous production.

Background

Fermented wheaten food such as steamed bread is a staple food which people eat three meals a day, and dough kneading and leavening are important processes when processing the fermented wheaten food. At present, the types of dough kneading machines and dough leavening machines on the market are various, but the two procedures of dough kneading and dough leavening must be respectively carried out on two devices, and the defects of the production mode are that:

1. the feeding and the material transferring are needed manually, and the operation of the equipment needs to be continuously monitored by manpower for 24 hours, so that much manpower is consumed, and the production efficiency is low.

2. The automatic continuous production can not be accomplished to current flour-mixing machine and dough leavening machine, and the reason lies in: even if automatic material transfer equipment is designed to connect two processes, the production rhythm of the dough kneading machine and the dough fermenting machine is difficult to be completely unified, so that the production capacity of the equipment cannot be brought into full play, and a plurality of problems of poor process matching can occur. In addition, the quality of the product is difficult to maintain because the material is not uniformly and continuously transferred.

3. In order to meet the food hygiene standards, the production line spliced by the existing equipment must be integrally arranged in an aseptic workshop, the space requirement of the aseptic workshop is high, and the cost for maintaining the aseptic environment is high.

4. The existing flour mixing machine and flour leavening machine are mostly vertical structures, the size is also large, and the flour mixing machine and the flour leavening machine can only be arranged on the ground during installation, so that the occupied ground space is large, and the equipment is difficult to be arranged in a three-dimensional manner.

The invention is further described below with reference to the accompanying drawings:

the device comprises two parallel cylinders, namely a cylinder A1 and a cylinder B9, wherein two ends of the two cylinders are respectively connected through a reversing pipeline 2, so that the two cylinders are connected into a circulating channel, a stirring shaft 5 and a spiral conveying shaft 3 are arranged in the cylinder A1, the axes of the stirring shaft 5 and the spiral conveying shaft 3 are overlapped, a spiral conveying shaft 3 is arranged in the cylinder B9, the stirring shaft 5 and the spiral conveying shaft 3 are driven by external power to rotate, a water adding port 7 and a dry powder adding port 8 are arranged on the cylinder A1 and correspond to the stirring shaft 5, and a yeast surface outlet 10 is arranged on the cylinder B9; the material conveying directions of the spiral conveying shafts 3 in the two cylinders are opposite; stirring shaft 5 is provided with stirring vane 6, spiral conveying shaft 3 on be provided with helical blade 4.

The working process of the invention is as follows:

1. after water and dry powder are added into a cylinder A1 through respective charging openings, the water and the dry powder enter a stirring section (namely, a section corresponding to the stirring shaft 5 in the cylinder A), and after the stirring shaft 5 rotates, the water and the dry powder are fully mixed under the action of the stirring blade 6.

In order to keep the dough moving in the mixing section, all or a part of the mixing blades 6 need to be adjusted to be inclined, so that the mixing blades 6 have the function of conveying materials like a helical blade. The specific angle of the stirring blade 6 can be flexibly adjusted according to the required dough kneading time.
