Description

Technical Field

[0001] This utility model belongs to the field of food processing technology, and in particular relates to a spiral cooling device for dough cakes. Background Technology

[0002] In modern food processing, the cooling process of dough directly impacts product quality and production efficiency. Spiral cooling devices, with their compact design, uniform cooling effect, and high degree of automation, have become a key piece of equipment in dough production lines. The working principle primarily utilizes a multi-layer spiral conveyor belt structure, allowing the dough to enter the cooling channel after high-temperature forming. The slow rotation of the spiral blades enables layer-by-layer conveying. A cooling air system blows vertically upwards or laterally from the bottom, creating a counter-current or cross-flow with the material to ensure uniform heat dissipation. Currently, this technology has been successfully applied to the industrial production of various dough products, including beef noodle soup, spring roll wrappers, and naan bread.

[0003] Comparing with Chinese Patent No. CN216432586U, a spiral cooling tower is disclosed, comprising: a spiral tower body; support columns for supporting the spiral tower body are fixedly connected at equal intervals on the cylindrical surface of the spiral tower body; and an external conveying mechanism, which includes a lifting transition mechanism and a bottom support mechanism. During food conveying, a fan is activated, and the generated airflow gathers from an airflow channel opened at the top of the open-type frustum cylinder into the inner cavity between the through-type frustum sleeve and the open-type frustum cylinder. The airflow passes through a condenser plate on a mounting plate, where external liquid nitrogen accumulates, causing the temperature at the condenser plate to drop. When the airflow passes through the mounting plate, its temperature is lowered, allowing the discharged cold airflow to quickly cool the hot food, thus ensuring the speed of food cooling and increasing processing efficiency.

[0004] However, the airflow in each layer of the aforementioned patent blows outward in parallel, which can easily interfere with the spiral tower body, causing airflow turbulence and seriously affecting the uniformity and efficiency of cooling. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a spiral cooling device for dough to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A spiral cooling device for dough cakes includes a main assembly for continuously spirally conveying and cooling dough cakes, and a flow guide assembly located at the center of the main assembly to guide airflow from the center to the outer periphery along the spiral conveying direction. An air intake assembly is installed at the top of the flow guide assembly to filter and push the airflow in, and a support assembly is installed at the bottom of the flow guide assembly to support, fix, and discharge wastewater. The main assembly includes a spiral tower body, with support columns fixedly installed at equal intervals on the cylindrical surface of the spiral tower body. A chain conveyor belt is installed inside the spiral tower body, and the chain conveyor belt spirally conveys along the spiral tower body. The flow guide assembly includes an inner chamber, with an outer chamber outside the inner chamber. Several air outlets are evenly distributed around the circumference of the outer chamber. A spiral guide plate is provided between the inner and outer chambers, dividing the space between the inner and outer chambers into spiral air channels. The support assembly includes a lower cover, with several support legs evenly distributed on the bottom surface of the lower cover. A waste discharge mechanism is installed at one corner of the bottom surface of the lower cover.

[0008] Furthermore: the air intake assembly includes an upper cover, on which a centrifugal fan and an air intake pipe are provided, and the centrifugal fan and the air intake pipe are connected through an air supply pipe.

[0009] Furthermore: the centrifugal fan is equipped with a filter head, and the air inlet pipe is inclined along the spiral air passage.

[0010] Furthermore: the spiral guide plate is aligned with the chain conveyor belt, and the spiral guide plate and the inner cylinder are welded together.

[0011] Furthermore, the air outlets are evenly distributed along the spiral air passage.

[0012] Furthermore, the upper cover and the lower cover are respectively bolted to the inner cylinder, and a sealing gasket is provided on the contact surface with the outer cylinder.

[0013] Furthermore: the waste discharge mechanism includes a waste discharge pipe facing the bottom end of the spiral air passage, and a waste discharge valve is installed on the waste discharge pipe.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] 1. Through the airflow channel (spiral air passage) designed with a spiral guide plate and the evenly distributed air outlets, the airflow is evenly blown from the inside to the outside along the spiral direction, which significantly improves the cooling uniformity and efficiency; the airflow direction is synchronized with the dough conveying direction (spiral matching), which prolongs the contact time between the airflow and the dough and enhances the heat exchange effect.

[0016] 2. The flow guiding components (inner / outer casing + spiral guide plate) are spatially aligned with the chain conveyor belt to form a compact spiral dual-channel structure (material conveying + airflow guidance), saving equipment space while achieving functional synergy; the inclined air inlet pipe ensures that the airflow path has no redundant turns, reducing energy consumption and ensuring that the airflow pressure is concentrated on cooling the dough.

[0017] 3. Through the synchronous spiral design of airflow and conveying, the problems of uneven cooling of dough, low efficiency and hygiene hazards are solved. It also has the advantages of compact structure, energy saving and environmental protection and easy maintenance, and is suitable for large-scale food processing production.

[0018] 4. The waste discharge mechanism (waste discharge pipe + valve) at the bottom of the spiral air duct can regularly remove condensate or wastewater dripping from the dough, preventing the accumulation of liquid from breeding bacteria or corroding the equipment, and reducing maintenance costs.

[0029] In this embodiment: the flow guiding assembly includes an inner casing 201, an outer casing 202 is disposed outside the inner casing 201, and a plurality of air outlets 204 are evenly distributed around the circumference of the outer casing 202. A spiral guide plate 203 is disposed between the inner casing 201 and the outer casing 202, and the spiral guide plate 203 divides the space between the inner casing 201 and the outer casing 202 into a spiral air passage 205; the spiral guide plate 203 is aligned with the chain conveyor belt 103, and the spiral guide...

At the same time, when passing the air outlet 204 on the circumference of the outer box cylinder 202, air is blown outwards.

[0030] In this embodiment: the air intake assembly includes an upper cover 301, on which a centrifugal fan 303 and an air intake pipe 302 are provided.
