Description

Technical Field

[0001] The utility model relates to the technical field of food processing equipment, in particular to a noodle cooling device. Background Technique

[0002] Noodles are a common food, originating in China and having a production and consumption history of more than four thousand years. Noodles are a healthy food that is simple to make, convenient to eat, rich in nutrition, and can be used as both a staple food and a fast food. They have long been accepted and loved by people all over the world. The production process of noodles includes dough mixing, ripening, sheet pressing, noodle cutting, drying, cutting, etc. Among them, the drying process is a very important process, which directly affects the production quality of noodles.

[0003] In the process of producing dried noodles, the noodles need to go through two steaming processes. After the first steaming of the noodles, the noodles need to go through a section of water cooling, and the water-cooled noodles then enter the second steaming machine for re-steaming. The quality of the noodles after cooling and re-steaming has been significantly improved.

[0004] In the previous cooling circulation system, most of them adopt the water-cooling cooling mode of cooling towers, that is, there is a cooling water tank for cooling noodles. When the noodles pass through the cooling water tank, heat exchange cooling is carried out by the water in the cooling water tank. The noodles cooled by the cooling water tank are directly transported to the next process for processing. The water in the cooling water tank is heated after heat exchange with the noodles, and the heated water is directly sent to the cooling tower for heat exchange cooling with the air, and then transported back to the cooling water tank for recycling.

[0005] It has the following technical problems:

[0006] The noodles are directly sent to the cooling water tank for cooling, increasing the cooling load of the cooling tower;

[0007] The heated water in the cooling water tank is sent to the cooling tower for heat exchange cooling with the air, with low heat exchange efficiency and poor cooling effect;

[0008] The water in the cooling tower is easy to contact with the dust in the air, and the dust is easily brought into the cooling water tank, which is easy to cause pollution and affect the production quality of noodles;

[0009] The noodles are only cooled by the cooling water tank in a single step, and the cooling effect needs to be improved.

[0010] Therefore, it is necessary to design a noodle cooling device with good cooling effect and no impact on noodle quality. Content of the Utility Model

The motor is connected to the transmission gear, the transmission gear is meshed with the conveying mesh chain, the conveying mesh chain is arranged around the cooling water tank, and the middle part of the upper end of the conveying mesh chain is immersed in the cooling water tank.

[0021] Further, a plurality of rotating rollers are provided on the frame, the plurality of rotating rollers are arranged parallel to each other, and the conveying mesh chain is arranged around the plurality of rotating rollers.

[0022] Further, at least one pair of tensioning gears are provided in the cooling water tank, each pair of tensioning gears is fixedly installed on the inner walls of both sides of the cooling water tank, and the tensioning gears are meshed with the conveying mesh chain.

[0023] Further, the air cooling device includes a fan and a support frame. The support frame is fixedly installed on the frame, the fan is connected to the support frame, and the fan is arranged above the conveying device and blows air towards the conveying device.

[0024] Further, an adjusting mechanism is provided between the fan and the support frame. One side of the adjusting mechanism is connected to the support frame, and the other side is connected to the fan. The adjusting mechanism is used to adjust the blowing angle of the fan.

[0025] Further, the adjusting mechanism includes an adjusting disk, a fan frame, and a locking nut.

After heat exchange, the water temperature in the circulating water pipe is significantly reduced, and the cooling water is re-conveyed back to the cooling water tank through the circulating water pipe for recycling, so as to ensure that the cooling water in the cooling water tank remains at a low temperature. Compared with the prior art where only a single-step cooling in the cooling water tank has poor cooling effect, the present utility model can significantly cool the noodles and effectively improve the cooling effect of the noodles through a multi-step combination of pre-air-cooling, water-cooling, and re-air-cooling; the water after heat exchange in the cooling water tank is cooled by heat exchange in the plate heat exchanger. During the heat exchange process, the water does not come into contact with the outside air, avoiding dust pollution and ensuring the production quality of the noodles. Description of the Drawings
