Description

Technical Field

[0001] The utility model belongs to the technical field of corn oil processing, and particularly relates to a corn oil deodorizing device. Background Art

[0002] In the production and refining process of corn oil, deodorization is a crucial step, which is directly related to the flavor, color, stability and safety of the final product. Traditional corn oil deodorization methods mainly include direct steam injection method, tower deodorization method and more advanced molecular distillation method, etc. However, these methods all have certain limitations in practical applications.

[0003] For the direct steam injection method, although steam can be quickly introduced into the oil, due to the short gas-liquid contact time and limited contact area, deodorization is often incomplete, affecting product quality. In addition, this method may also cause excessive oxidation of the oil due to excessive steam volume, reducing the nutritional value of the oil.

[0004] The tower deodorization method prolongs the gas-liquid contact time and improves the deodorization effect by increasing the tower height and fillers. However, this method has problems such as complex structure, large floor area and high energy consumption. At the same time, the fillers are easily blocked and need to be cleaned and replaced regularly, increasing the difficulty and cost of equipment maintenance.

[0005] Although the molecular distillation method can achieve efficient deodorization, its equipment investment is large, operation is complex, and the quality requirements for the raw material oil are relatively high, which is not suitable for all types of corn oil processing.

[0006] Therefore, there is an urgent need in the market for a corn oil deodorizing device that can not only ensure the deodorization effect, but also reduce energy consumption and simplify equipment maintenance. Content of the Utility Model

[0007] Aiming at the above problems, the purpose of the utility model is to provide a corn oil deodorizing device to solve the problems of poor deodorization effect, complex equipment structure and difficult maintenance existing in the existing corn oil deodorizing device.

[0008] To achieve the above purpose, the technical solution adopted by the utility model is: a corn oil deodorizing device, including a lower housing, the top of the lower housing is bolted to an upper housing, an oil inlet and an exhaust port are arranged on the upper housing, an oil outlet and an air inlet pipe are arranged at the bottom of the lower housing, a flow guiding component is installed inside the upper housing, the flow guiding component includes a connecting frame, both ends of the connecting frame are respectively connected to the inner wall of the upper housing and a main rod body, a first flow guiding plate and a fixing frame two are installed at intervals on the main rod body, the outer side of the first flow guiding plate is connected to a third flow guiding plate through a fixing frame one, the end of the fixing frame two is connected to a second flow guiding plate, the first flow guiding plate and the third flow guiding plate are in a tapered plate structure with a narrow top and a wide bottom, and the second flow guiding plate is in a tapered plate structure with a wide top and a narrow bottom.

[0009] The beneficial effects of the present utility model are as follows: Through the design of multiple detachable and simple-structured conical guide plates with different slopes, sufficient contact between the downward-flowing corn oil and the upward-flowing steam is achieved, thereby improving the deodorization efficiency, reducing energy consumption, and simplifying equipment maintenance.

[0010] To ensure the uniformity of the thickness of the oil film on the guide plate;

[0011] As a further improvement of the above technical solution: The axes of the first guide plate and the second guide plate are collinear with the axis of the oil inlet.

[0012] The beneficial effect of this improvement is that after the oil body flows into the interior of the lower housing through the oil inlet, it is effectively and uniformly thinned into an oil film by the second guide plate and the first guide plate, so as to uniformly contact the steam.

[0013] To enable the steam to uniformly contact the oil film on the first guide plate and the second guide plate;

[0014] As a further improvement of the above technical solution: The port of the air inlet pipe located inside the lower housing is vertically upward and the axis is collinear with the axes of the first guide plate and the second guide plate.

[0015] The beneficial effect of this improvement is that the whole air inlet pipe can uniformly contact the oil film thinned on the second guide plate and the first guide plate during the upward flow process.

[0016] To fully ensure the guiding effects of the third guide plate and the second guide plate;

[0017] As a further improvement of the above technical solution: One end of the third guide plate and the second guide plate is slidably connected to the inner wall of the lower housing.

[0018] The beneficial effect of this improvement is that a small gap is maintained between the third guide plate and the second guide plate and the inner wall of the lower housing, so that the oil body and the steam can be effectively guided by the third guide plate and the second guide plate.

[0019] To ensure the installation stability of the third guide plate and the second guide plate;

[0020] As a further improvement of the above technical solution: Both the first fixing frame and the second fixing frame are composed of a plurality of plate structures arranged around the axis of the main rod body.

[0021] The beneficial effect of this improvement is that the first fixing frame and the second fixing frame composed of multiple plates can provide stable support for the third guide plate and the second guide plate.

[0022] To enable the steam to uniformly contact the oil body falling from the second guide plate;

[0023] As a further improvement of the above technical solution: the inner diameter of the bottom end of the second deflector is not greater than the inner diameter of the top end of the third deflector.

[0024] The beneficial effect of this improvement is that the steam is in full contact with the oil body dripping from the bottom end of the second deflector under the guiding action of the third deflector.

[0025] The parts not involved in this device are the same as the prior art or can be implemented using the prior art. Description of the Drawings

Detailed Embodiments

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the drawings. The description of this part is only exemplary and explanatory, and should not have any restrictive effect on the protection scope of the present invention.

[0032] Embodiment 1:

[0033] As Figure 1As shown in Figure 4, a corn oil deodorization device includes a lower housing 1. The top of the lower housing 1 is bolted to an upper housing 2. An oil inlet 4 and an exhaust port 5 are provided on the upper housing 2. An oil outlet 6 and an air inlet pipe 7 are provided at the bottom of the lower housing 1. A diversion component 3 is installed inside the upper housing 2. The diversion component 3 includes a connecting frame 31. The two ends of the connecting frame 31 are respectively connected to the inner wall of the upper housing 2 and a main rod body 32. A first diversion plate 33 and a second fixing frame 37 are installed at intervals on the main rod body 32. The outer side of the first diversion plate 33 is connected to a third diversion plate 36 through a first fixing frame 35. The end of the second fixing frame 37 is connected to a second diversion plate 34. The first diversion plate 33 and the third diversion plate 36 are in the shape of a tapered plate with a narrower top and a wider bottom. The second diversion plate 34 is in the shape of a tapered plate with a wider top and a narrower bottom. Through the design of multiple detachable and simple-structured tapered diversion plates with different slopes, sufficient contact between the downward-flowing corn oil and the upward-flowing steam is achieved, thereby improving the deodorization efficiency, reducing energy consumption, and simplifying equipment maintenance. The axes of the first diversion plate 33 and the second diversion plate 34 are collinear with the axis of the oil inlet 4. After the oil body flows into the interior of the lower housing 1 through the oil inlet 4, it is effectively and evenly thinned into an oil film by the second diversion plate 34 and the first diversion plate 33, so as to contact the steam evenly. The port of the air inlet pipe 7 located inside the lower housing 1 is vertically upward and its axis is collinear with the axes of the first diversion plate 33 and the second diversion plate 34. The whole air inlet pipe 7 can evenly contact the oil film thinned on the second diversion plate 34 and the first diversion plate 33 during the upward flow process. One end of the third diversion plate 36 and the second diversion plate 34 is slidably connected to the inner wall of the lower housing 1. A small gap is maintained between the third diversion plate 36, the second diversion plate 34 and the inner wall of the lower housing 1, so that the oil body and the steam can be effectively guided by the third diversion plate 36 and the second diversion plate 34. The first fixing frame 35 and the second fixing frame 37 are both composed of a plurality of plate structures arranged around the axis of the main rod body 32. The first fixing frame 35 and the second fixing frame 37 composed of multiple plates can provide stable support for the third diversion plate 36 and the second diversion plate 34. The inner diameter of the bottom end of the second diversion plate 34 is not greater than the inner diameter of the top end of the third diversion plate 36. The steam is in full contact with the oil body dripping from the bottom end of the second diversion plate 34 under the diversion action of the third diversion plate 36.

[0034] The working principle of this technical solution is as follows: The oil body enters the interior of the housing composed of the lower housing 1 and the upper housing 2 from top to bottom through the oil inlet 4, and the steam enters the interior of the housing composed of the lower housing 1 and the upper housing 2 from bottom to top through the air inlet pipe 7. When the oil body flows downward, it is first blocked by the first deflector 33 and is guided and dispersed on the surface of the first deflector 33 to form a thin and uniform oil film, and then falls on the inner wall of the second deflector 34 and continues to spread thinly into a uniform oil film, thus greatly increasing the contact area and contact time with the rising steam. Moreover, the design of the conical plates with different slopes can also promote the turbulent motion of the oil liquid, further improving the gas-liquid mixing effect. During the process of the steam flowing upward through the second deflector 34, it fully contacts the oil film on the inner wall of the second deflector 34, and then under the guidance of the third deflector 36, it first fully contacts the oil film on the outer side surface of the first deflector 33, and then flows upward to fully contact the uniformly falling oil body, effectively removing the bad odor substances in the grease.
