This dynamic cooling method can effectively adapt to extract liquid materials of different temperatures and flow rates, ensuring stable and reliable cooling effect.

Description

Technical Field

[0001] This utility model relates to the field of extract processing technology, and in particular to a tube reflux cooling device for extract materials. Background Technology

[0002] In many fields such as pharmaceuticals, chemicals, and food processing, extracts, after being boiled at high temperatures, need to be rapidly cooled to a suitable temperature before proceeding to subsequent processes such as membrane concentration. This has a crucial impact on the efficiency and quality of the entire production process. The cooling efficiency of the extracts not only determines the speed of the production process but can also affect the chemical properties and active ingredient content of the materials due to improper cooling.

[0003] Currently, common cooling methods for extracts include natural cooling, air cooling, and simple pipeline cooling. Natural cooling, as the name suggests, involves placing the high-temperature extract in a room-temperature environment, relying on natural convection heat transfer to lower the temperature. However, this method suffers from extremely slow cooling rates, often requiring several hours or even longer to reach the desired temperature, significantly extending production cycles and reducing equipment utilization. While air cooling accelerates the cooling process to some extent, it is greatly affected by environmental factors, and its cooling effect is still not ideal for high-viscosity or high-flow-rate extracts. Pipeline cooling typically involves the extract flowing in a straight pipe while a cooling medium circulates through the outer wall for heat exchange. Although this cooling method is relatively direct, the simple pipe structure limits the heat exchange area, and the fluid flow within the pipe is mostly laminar with a thick boundary layer, limiting the heat transfer rate and making it difficult to meet the requirements for efficient cooling. Utility Model Content

[0004] The purpose of this invention is to provide a tube reflux cooling device for extract materials, which can overcome the problem of insufficient reflux cooling efficiency of extract materials.

[0005] To achieve the above objectives, a tube reflux cooling device for extract liquid material is provided, including a reflux cooling box. A rotary sealing assembly is fixedly connected to both the front and rear side walls of the reflux cooling box. The rotary sealing assembly consists of a sealing outer sleeve and a sealing inner sleeve. A first connecting pipe and a second connecting pipe are fixedly connected inside the sealing inner sleeve. A plurality of liquid inlet branch pipes are fixedly connected to one end of the first connecting pipe, and a plurality of liquid outlet branch pipes are fixedly connected to one end of the second connecting pipe. A spiral reflux pipe is fixedly connected between each of the liquid inlet branch pipe and the liquid outlet branch pipe. An air pump is provided on the left side of the reflux cooling box. An air diffuser is fixedly connected to the output end of the air pump. An air guide is fixedly connected to the right end of the air diffuser. A cold water inlet pipe is fixedly connected to the right side wall of the reflux cooling box near the top. A spray head is fixedly connected to the output end of the cold water inlet pipe.

[0006] According to the tube reflux cooling device for extracting liquid material, the cross-sectional area of ​​the diffuser gradually increases from left to right, so that the airflow discharged by the air pump gradually diffuses.

[0007] According to the aforementioned tube reflux cooling device for extracting liquid materials, the air guide frame is fixedly connected to the inner wall of the reflux cooling box to improve the stability of the air outlet of the air guide frame. The air outlet end of the air guide frame faces the middle of the lower inner wall of the reflux cooling box. The gas ejected from the air guide frame generates airflow at the bottom of the spiral reflux tube, which accelerates the liquid flow near the spiral reflux tube and thus accelerates the heat dissipation of the outer wall of the spiral reflux tube.

[0008] According to the tube reflux cooling device for extracting liquid material, a plurality of the spiral reflux tubes are arranged in a circumferential shape on the outer wall of the rotary sealing assembly, making the spiral reflux tubes more stable when rotating.

[0009] According to the aforementioned tube reflux cooling device for extract material, an inlet pipe is fixedly connected inside the rear sealing jacket, through which the extract material spirally refluxes back into the tube, and an outlet pipe is fixedly connected inside the front sealing inner jacket, facilitating the discharge of the cooled extract material.

[0010] According to the aforementioned tube reflux cooling device for extract material, the outer sealing sleeve and the inner sealing sleeve are rotatably connected, and a mechanical seal is provided between the outer sealing sleeve and the inner sealing sleeve to improve the sealing performance between the outer sealing sleeve and the inner sealing sleeve.

[0011] According to the aforementioned tube reflux cooling device for extract materials, a hot water outlet pipe is fixedly connected to the right side wall and near the lower side of the reflux cooling tank to facilitate the discharge of the heat-absorbing coolant. A second control valve is fixedly connected to the middle of the hot water outlet pipe to control the connection of the hot water outlet pipe. A first control valve is fixedly connected to the middle of the cold water inlet pipe to control the connection of the cold water inlet pipe. The outlet of the spray head faces directly above the rotation center of the spiral reflux pipe, which can accelerate the rotation of the spiral reflux pipe while cooling it.

[0012] According to the aforementioned tube reflux cooling device for extracting liquid materials, the interior of the reflux cooling box is filled with coolant to facilitate the cooling of the spiral reflux tube in the reflux cooling box.

[0013] This utility model has the following beneficial effects: 1. Compared with existing technologies, the spiral reflux tube in this device can rotate, causing the extract to flow in a spiral pattern within the tube, increasing the cooling path and time, thereby improving cooling efficiency. During rotation, the liquid inside the tube adheres tightly to the tube wall due to centrifugal force, enhancing heat exchange. Simultaneously, the rotation drives the coolant to form a swirling flow, promoting its circulation, breaking down the outer boundary layer of the tube, and further accelerating heat transfer. This dynamic cooling method can effectively adapt to extracts of different temperatures and flow rates, ensuring stable and reliable cooling performance.

[0014] 2. Compared with the existing technology, this device is equipped with a spray head and an air pump. The spray head sprays cold water directly above the rotation center of the spiral reflux pipe, thereby accelerating the rotation of the spiral reflux pipe. The airflow generated by the air pump passes through the diffuser and guide frame, and can form an airflow at the bottom of the spiral reflux pipe, breaking the laminar boundary layer of the coolant outside the pipe, enhancing the turbulence of the coolant, improving the heat exchange efficiency between the coolant and the outer wall of the spiral reflux pipe, and accelerating the cooling speed of the extract material. The combination of the two can effectively improve the cooling effect of the device. Attached Figure Description
