AI Technical Summary
The existing deodorization tower has a problem of uneven contact between oil and steam, resulting in insufficient deodorization.
The system employs a combination of spiral heat exchange plates and steam pipes. After entering the deodorization tower through the inlet pipe, the oil flows along the spiral heat exchange plates and is ejected through the steam nozzles on the outer surface of the steam pipes, increasing the contact area and contact time between the oil and the heat source.
It achieves uniform heating of oils and rapid discharge of volatile substances, thus improving the deodorization effect.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of edible oil processing technology, specifically to a deodorization tower. Background Technology
[0002] During the production of edible oil, raw oil often contains unwanted impurities and odorous substances, which may include low-molecular-weight aldehydes, ketones, free fatty acids, unsaturated hydrocarbons, etc. These substances not only affect the flavor of edible oil but may also negatively impact its quality. Therefore, in order to produce high-quality edible oil, it is necessary to purify it through the refining process. Deodorization is a crucial step in the refining process. The deodorization tower utilizes the fact that small-molecule odorous organic compounds in the oil are more volatile than triglycerides under high temperature and negative pressure. When water vapor passes through the odorous oil, the water vapor is saturated with the volatile odor components and escapes according to their partial pressure ratio, thereby achieving the purpose of deodorization.
[0003] Chinese utility model patent CN218372179U discloses a novel deodorizing tower for camellia oil processing, comprising a tower body and a steam pipe. The top of the tower body is equipped with a pressure gauge, a vacuum pump, and an oil spraying device. Inside the tower body, a first diversion plate is fixedly installed below the oil spraying device. Below the first diversion plate is a first spray pipe connected to the steam pipe. Below the first spray pipe is a second diversion plate, and below the second diversion plate is another second spray pipe connected to the steam pipe. At the bottom of the tower body, below the second spray pipe, an inclined plate is fixedly installed. A discharge pipe is installed at the bottom of the inclined plate. The first diversion plate guides the sprayed camellia oil in layers, while oil droplets leak along the second circular hole at the end of the Y-shaped groove. During this process, the first spray pipe continuously delivers high-temperature steam to the space between the first diversion plates, ensuring sufficient contact with the oil. The extended contact time and area facilitate deodorization, resulting in a good deodorization effect.
[0004] In the aforementioned utility model patent, although the part of the oil near the nozzle can fully contact the steam, the part of the oil farther from the nozzle may not be able to fully contact the steam, resulting in uneven contact and insufficient deodorization. Therefore, a multi-stage deodorization tower is proposed to solve the above problems. Utility Model Content

[0024] Please see Figure 1-4A deodorization tower includes a deodorization tower body 1, a treatment chamber 10 inside the deodorization tower body 1, a spiral heat exchange plate 13 protruding from the inner wall of the treatment chamber 10, a maintenance cover 2 attached to the top opening of the treatment chamber 10, a steam pipe 3 extending downward through the maintenance cover 2, an oil inlet pipe 7 on the maintenance cover 2, the oil outlet end of the oil inlet pipe 7 being located directly above the spiral heat exchange plate 13, an oil collection chamber 11 at the bottom of the treatment chamber 10, an oil outlet pipe 12 extending to the outside through the deodorization tower body 1 at the bottom of the oil collection chamber 11, and multiple steam nozzles 9 spaced apart along the axial direction of the steam pipe 3 on the surface of the steam pipe 3.
[0025] Through the coordinated arrangement of the spiral heat exchange plate 13 and steam pipe 3, the oil can enter the deodorization tower through the oil inlet pipe 7 and flow downward along the spiral heat exchange plate 13. At the same time, high-temperature steam is sprayed onto the spiral heat exchange plate 13 through multiple steam nozzles 9 on the outer surface of the steam pipe 3, thereby increasing the contact area between the oil and the heat source, so that the oil can be heated evenly and volatiles can be discharged quickly, thus improving the deodorization effect.
[0026] Specifically, in this embodiment, the inspection cover 2 is provided with two symmetrical first connecting blocks 4, the deodorization tower body 1 is provided with two symmetrical second connecting blocks 5, the first connecting block 4 is provided with a plug-in block 6, and the second connecting block 5 is provided with a groove that matches the plug-in block 6. The first connecting block 4 and the second connecting block 5 are connected and fixed by connecting bolts.
[0027] The first connecting block 4 and the second connecting block 5 can effectively connect the deodorization tower body 1 and the inspection cover 2, and facilitate quick assembly and disassembly between the inspection cover 2 and the deodorization tower body 1.
[0028] Specifically, in this embodiment, an annular groove 16 is provided on the top of the deodorization tower body 1, and a sealing ring 17 is provided in the annular groove 16.
[0029] The sealing ring 17 ensures the airtightness of the connection between the deodorization tower body 1 and the inspection cover 2.
[0030] Specifically, in this embodiment, an external steam generator is connected to the end of the steam pipe 3 that is away from the main body 1 of the deodorization tower.
[0031] Specifically, in this embodiment, the bottom of the deodorization tower is provided with four support columns 8 arranged in a matrix.
[0032] Specifically, in this embodiment, both the oil inlet pipe 7 and the oil outlet pipe 12 are equipped with solenoid valves, which are electrically connected through the control box.
[0033] Specifically, in this embodiment, a spiral heating tube 14 is provided inside the spiral heat exchange plate 13, and multiple arc-shaped holes 15 are opened on the surface of the spiral heat exchange plate 13.
[0034] The electric heating tube 14 allows the spiral heat exchange plate 13 to have a certain amount of heat, so that the grease can be heated when it comes into contact with the spiral heat exchange plate 13. Under the synchronous action of the electric heating tube 14 and the high-temperature steam, the grease can be heated faster and volatiles can be discharged. The arc-shaped hole 15 slows down the flow rate of the grease from the spiral heat exchange plate 13, thereby prolonging the contact time between the grease and the spiral heat exchange plate 13, and thus making the deodorization more complete.
[0035] It should be noted that the steam generator, as well as the electric heating tube and solenoid valve mentioned in the text, are all connected to the external main controller and the mains power. Furthermore, the more detailed structure and connection relationship of the deodorization tower are described in the prior application of patent number CN218372179U, which discloses a novel deodorization tower for camellia oil processing. This application will not repeat the description.
[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
