Technical Field
[0001] This utility model relates to the field of food processing equipment, and more specifically, to an automatic dough kneading device for high-fat dough. Background Technology
[0002] Traditional dough mixing equipment has significant drawbacks when processing high-fat dough: vigorous mixing leads to excessive gluten formation, affecting the crispness of the finished product; uneven fat distribution affects the texture of the dough; increased dough temperature accelerates gluten network development; and it is impossible to precisely control the mixing intensity and time.
[0003] A search revealed that Chinese patent CN205962556U discloses an "automatic bread production line," comprising a machine body and sequentially arranged components: a feeding platform for placing dough to be processed, a pre-pressing roller connected to the feeding platform for pre-pressing the dough, a thinning roller assembly for thinning the pre-pressed dough, a shaping assembly for shaping the thinned dough, a conveyor belt connected to the shaping assembly, a filling machine located on the conveyor belt path for adding filling to the dough, a rolling roller for rolling the filled dough, and a shaping machine located at the end of the conveyor belt. The shaping machine includes a cutting device for cutting and pinching the filled dough. This automatic bread production line can add filling to the kneaded dough and pinch and seal the ends of the filled dough. The entire automatic bread production line has a high degree of automation, which to a certain extent ensures food hygiene and improves food safety. Furthermore, the safety design is in place, achieving safe bread production. However, the following defects still exist:
[0004] (1) Currently available dough kneading devices, when used in food processing equipment, are difficult to automatically knead dough and use flexible guide plates to make the dough flow path irregular, thereby reducing gluten formation.
[0005] (2) Currently available dough mixing devices are difficult to reduce the amount of flour flying when adding flour in food processing equipment, which may affect the health of workers who are exposed to flour dust for a long time. Utility Model Content
[0006] The purpose of this invention is to address the problems of difficulty in automatically kneading dough and the irregular flow path of dough caused by the use of flexible guide plates, which leads to the inability to reduce gluten formation.
[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0008] The present invention is as follows: an automatic dough kneading device for high-oil dough, comprising a cooling jacketed barrel, a support leg fixedly connected to the bottom of the cooling jacketed barrel, a cover plate fixedly connected to the top of the cooling jacketed barrel, an intelligent control panel provided on the front and side of the cooling jacketed barrel, a feeding port provided on the top of the cooling jacketed barrel, a discharging port provided on the side of the cooling jacketed barrel, and a dough kneading device provided inside the cooling jacketed barrel;

The output shaft of the variable frequency drive motor is fixedly connected to a stirring shaft. A threaded block is fixedly connected to the circumferential surface of the stirring shaft. A flexible stirring arm is fixedly connected to the side of the threaded block. A curved stirring blade is fixedly connected to the circumferential surface of the stirring shaft.
[0010] As a preferred technical solution of this utility model, a planetary gear system is provided inside the cooling jacket barrel, and a flexible guide plate is fixedly connected inside the cooling jacket barrel. The function of the planetary gear system is to reduce the high-speed rotation of the variable frequency drive motor, while causing the stirring shaft to rotate and revolve.
[0011] As a preferred technical solution of this utility model, a coolant inlet is provided on the side of the cooling jacket barrel, and a coolant outlet is provided on the side of the cooling jacket barrel. The function of the cooling jacket barrel is to maintain a low temperature environment, reduce gluten formation, and prevent the dough from deteriorating.
[0012] As a preferred technical solution of this utility model, the number of the flexible stirring arm and the curved stirring blade is set to two, and they are symmetrical to each other along the vertical central axis of the stirring shaft. The function of the stirring shaft is to drive the flexible stirring arm and the curved stirring blade to rotate.
[0013] As a preferred technical solution of this utility model, the interior of the cooling jacket barrel is provided with a protective device, the protective device including a dust cover, the dust cover being rotatably connected to the top of the cover plate, a push rod being fixedly connected to the bottom of the dust cover, and a protective plate being fixedly connected to the side of the push rod.
[0014] As a preferred technical solution of this utility model, the bottom of the cover plate is rotatably connected to a rotating shaft, the circumferential surface of the rotating shaft is rotatably connected to a sliding plate, the circumferential surface of the rotating shaft is fixedly connected to a torsion spring, the end of the torsion spring away from the rotating shaft is fixedly connected to the top of the sliding plate, and the inside of the cover plate is provided with a slot.

[0015] As a preferred technical solution of this utility model, the top of the skateboard is located on the displacement trajectory of the push rod, the side of the skateboard is located inside the groove, and the push rod is used to push the skateboard downward.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. The dough mixing device is designed so that when the output shaft of the variable frequency drive motor rotates, it drives the stirring shaft to rotate. When the stirring shaft rotates, it drives the threaded block and the flexible stirring arm to rotate. When the stirring shaft rotates, it drives the curved stirring blade to rotate, thereby achieving the mixing of the mixture inside the cooling jacket barrel. When the flexible stirring arm and the curved stirring blade are mixing, the mixture will touch the flexible guide plate inside the cooling jacket barrel, which can make the dough flow path irregular, thereby reducing the effect of gluten formation.
[0018] 2. The protective device allows flour to be added by opening the dust cover. When flour is added, it will flow down the slide into the cooling jacket due to gravity. After the flour is added, the slide will return to its original position due to the force of the rotating shaft. There may be residual flour on the slide after the flour is added. When the dust cover is closed, the dust cover will drive the push rod to move downward. When the dust cover moves downward, it will push the slide to rotate downward using the rotating shaft, thereby achieving the effect of allowing the residual flour on the slide to also enter the cooling jacket.
