Abstract
Description
Technical Field
[0001] The utility model relates to the field of edible oil processing, and more specifically, to an edible oil refining device. Background Art
[0002] Edible oil, also known as "cooking oil", refers to animal or vegetable oils used in the process of making food, which is liquid at room temperature. Edible oil needs to be refined during processing, mainly including degumming, deacidification, decolorization, deodorization and dewaxing. Among them, the oil after degumming and deacidification is called semi-refined oil, and then the oil after decolorization, deodorization and dewaxing is called fully refined oil.
[0003] When producing semi-refined oil, the existing main degumming method is hydration degumming. Its main principle is to utilize the hydrophilicity of colloid-soluble impurities. A certain amount of hot water is added to the hot crude oil being stirred. The colloid-soluble impurities in the crude oil absorb water, aggregate and agglomerate to form a substance similar to a colloidal ball, and then the impurities are discharged through sedimentation separation, that is, the degumming of the crude oil is completed. After degumming, an alkaline substance is added to the degummed crude oil. By using the acid-base neutralization effect, the free fatty acids in the crude oil can be removed. In this process, a by-product soapstock is generated. After separating the generated soapstock, the deacidification of the crude oil is completed. After the above deacidification and degumming treatments, the required semi-refined oil is obtained.
[0004] Since edible oil needs to be heated during degumming and deacidification, and hot water is also required, the power consumption generated by heating usually accounts for a large part of the cost. Existing degumming and deacidification equipment usually sets heating elements inside to heat the crude oil, and separately sets a heating device outside the equipment to heat the water, and then adds the hot water to the crude oil. This separate heating method wastes a lot of heat, has a low heat utilization rate, resulting in high heating costs. In addition, currently, the degumming and deacidification of edible oil are usually carried out in different equipment, which wastes a certain amount of transfer time, affects the processing efficiency, and using multiple equipment further increases the construction cost, raising the cost. Summary of the Utility Model
[0005] In view of this, the utility model provides an edible oil refining device that can effectively save costs.
[0006] The purpose of the utility model is achieved through the following technical solutions:
[0007] An edible oil refining device includes: a refining tank, a heat exchanger, a heating device, a liquid storage tank, and a stirring assembly. The refining tank includes an oil inlet, an oil outlet, and a discharge port located at the bottom. A heating coil is provided in the inner cavity of the refining tank, and the inlet end and the outlet end of the heating coil penetrate through the refining tank. The heat exchanger is provided on one side of the refining tank, and the heat exchanger is connected with a water inlet pipe and a discharge pipe. The outlet end of the heating coil is connected to the heat exchanger. The heating device is provided on one side of the refining tank, and the heating device is connected to the heat exchanger through a pipeline. The liquid storage tank is provided on the top of the refining tank for storing lye, and the liquid storage tank is provided with a connecting pipeline connected to the inner cavity of the refining tank. The connecting pipeline is provided with a branch connected to the heating device. The stirring assembly includes a stirring drive motor, a rotating rod connected to the output end of the stirring drive motor, and a plurality of stirring paddles connected to the rotating rod. The stirring drive motor is provided on the top of the refining tank, and the rotating rod is provided inside the refining tank.
[0008] In the above technical solution, a refining device applicable to degumming and deacidification of edible oil is provided. When treating crude oil, the crude oil enters the inner cavity of the refining tank from the oil inlet, and the heat transfer medium (such as heat-conducting oil) enters from the inlet end of the heating coil. The crude oil in the refining tank is heated to a suitable degumming temperature through the heat transfer medium. After passing through the heating coil, the heat transfer medium enters the heat exchanger and exchanges heat with the water entering from the water inlet pipe. After the heat exchange is completed, it is discharged from the discharge pipe. The heat-exchanged water enters the heater through a pipeline. After the heater heats the water to a suitable temperature, it is added to the crude oil in the refining tank through the branch. While adding hot water to the crude oil, the stirring drive motor drives the rotating rod and the stirring paddles on the rotating rod to rotate to stir the crude oil. After stirring for a certain period of time, the heating of the heat transfer medium and the stirring are stopped. After the crude oil stands and settles for a period of time, the gum-soluble impurities settled at the bottom of the refining tank are discharged through the discharge port. Thus, the degumming of the crude oil is completed. After the degumming is completed, the heat transfer medium is continuously introduced to heat the crude oil to a suitable deacidification temperature. The heat transfer medium continues to enter the heat exchanger to exchange heat with water, and the heat-exchanged water continues to enter the heater to be heated to a suitable temperature. At this time, an alkaline solution is added to the liquid storage tank. The alkaline solution is mixed with the hot water in the branch through the connecting pipeline and then added to the crude oil in the storage tank. At the same time, the stirring assembly stirs. At this time, the free fatty acids in the crude oil form soapstock under the action of acid-base neutralization. After a certain period of time, the stirring is stopped. Subsequently, after a period of settlement, the soapstock accumulates at the bottom of the refining tank and is then discharged through the discharge port to complete the deacidification of the crude oil.
[0009] Optionally, as a possible implementation manner, a spraying mechanism is provided at the top of the inner cavity of the refining tank. The spraying mechanism is connected to one end of the connecting pipeline located in the inner cavity of the refining tank, and the spraying mechanism is provided with a plurality of nozzles.
[0010] In the above technical solution, through multiple nozzles of the spraying mechanism, hot water and alkaline liquid are added to the crude oil in a spraying manner, so that they diffuse faster and are more evenly distributed in the crude oil, and the removal effect is better.
[0011] Optionally, as a possible implementation manner, the spraying mechanism includes a water distribution plate, and the nozzles are spaced apart and distributed at the bottom of the water distribution plate.
[0012] In the above technical solution, the water distribution plate is used to distribute the incoming liquid to each nozzle to ensure uniform spraying.
[0013] Optionally, as a possible implementation manner, a first solenoid valve is installed at the discharge port, and second and third solenoid valves are respectively installed on the connecting pipeline and the branch pipeline.
[0014] In the above technical solution, the first solenoid valve is used to control the opening and closing of the discharge port to control the discharge of colloidal impurities and soapstock, and the second and third solenoid valves are respectively used to control the entry of alkaline liquid and hot water into the refining tank.
[0015] Optionally, as a possible implementation manner, a plurality of fins are provided at intervals on the stirring paddle, and the fins are symmetrically distributed on both sides of the stirring paddle.
[0016] In the above technical solution, the fins are used to increase the contact area with the crude oil during the stirring process, so that the stirring is more sufficient and uniform, and the removal effect is improved.
[0017] Optionally, as a possible implementation manner, a cleaning component is further included. The cleaning component includes a lifting driving member provided at the top of the refining tank, and a scraping plate connected to the output end of the lifting driving member. The scraping plate is located in the inner cavity of the refining tank and fits against the side wall of the refining tank.
[0018] In the above technical solution, after the degumming and deacidification of a batch of crude oil are completed, the scraping plate is driven to move down by the lifting driving member to scrape and collect the residual part attached to the side wall, which can reduce a certain amount of waste, and the cleaning work of the inner wall of the refining tank is completed, avoiding pollution and affecting the next processing work, especially when processing different types of crude oil. In addition, by setting up the cleaning component to perform automatic cleaning work, manual cleaning is not required, which effectively saves the cleaning time and reduces the downtime of the device, improving the processing efficiency.
[0019] Optionally, as a possible implementation manner, the scraping plate is a hollow circular ring structure, and an elastic pad is provided on the side of the scraping plate that fits against the side wall of the refining tank.
[0020] In the above technical solution, the scraper is in a circular ring structure. The side of the scraper that fits against the side of the refining tank is the outer peripheral surface of the circular ring. An elastic pad is provided on this surface. The elastic pad has a certain elasticity, which can ensure a tight fit with the side wall of the refining tank while not scratching the side wall.
[0021] Optionally, as a possible implementation, a temperature sensor is provided at the top of the refining tank, and the probe of the temperature sensor extends into the inner cavity of the refining tank.
[0022] In the above technical solution, after the crude oil is added to the refining tank, the probe of the temperature sensor is immersed in the crude oil, thereby measuring the temperature of the crude oil, ensuring that the crude oil is at a suitable processing temperature, and guaranteeing the effects of degumming and deacidification.

[0035] Please refer to Figure 1, this embodiment provides an edible oil refining device for degumming and deacidifying edible oil, which includes: a refining tank 1, a heat exchanger 2, a heating device 3, a liquid storage tank 4 and a stirring assembly 6. The refining tank 1 includes an oil inlet 11, an oil outlet 12, and a discharge port 13 located at the bottom. A heating coil 14 is provided in the inner cavity of the refining tank 1, and the inlet end 141 and the outlet end 142 of the heating coil 14 penetrate through the refining tank 1; the heat exchanger 2 is provided on one side of the refining tank 1, and the heat exchanger 2 is connected with a water inlet pipe 21 and a discharge pipe 22, and the outlet end 142 of the heating coil 14 is connected to the heat exchanger 2; the heating device 3 is provided on one side of the refining tank 1, and the heating device 3 is connected to the heat exchanger 2 through a pipeline; the liquid storage tank 4 is provided on the top of the refining tank 1 for storing lye, and the liquid storage tank 4 is provided with a connecting pipeline 5 connected to the inner cavity of the refining tank 1, and the connecting pipeline 5 is provided with a branch 51 connected to the heating device 3; the stirring assembly 6 includes a stirring drive motor 61, a rotating rod 62 connected to the output end of the stirring drive motor 61, and a plurality of stirring paddles 63 connected to the rotating rod 62. The stirring drive motor 61 is provided on the top of the refining tank 1, the rotating rod 62 is provided inside the refining tank 1, and the top of the rotating rod 62 passes through the refining tank 1 and is connected to the stirring drive motor 61.
[0036] Among them, both the heat exchanger 2 and the heating device 3 are conventional devices in the prior art, and appropriate models can be selected according to actual needs, and their specific structures will not be elaborated here.
[0037] In this embodiment, when processing crude oil, the crude oil enters the inner cavity of the refining tank 1 from the oil inlet 11, and the heat-conducting oil enters from the inlet end 141 of the heating coil 14. The crude oil in the refining tank 1 is heated to a suitable degumming temperature by the heat-conducting oil. After passing through the heating coil 14, the heat-conducting oil enters the heat exchanger 2 and exchanges heat with the water entering from the water inlet pipe 21. After the heat exchange is completed, it is discharged from the discharge pipe 22. The heat-exchanged water enters the heating device 3 through a pipeline. After the heating device 3 heats the water to a suitable temperature, it is added to the crude oil in the refining tank 1 through the branch 51. While adding hot water to the crude oil, the stirring drive motor 61 drives the rotating rod 62 and the stirring paddle 63 on the rotating rod 62 to rotate, and stirs the crude oil. After stirring for a certain period of time, the heating of the heat-conducting oil and the stirring are stopped. After the crude oil stands and settles for a period of time, the colloidal impurities settled at the bottom of the refining tank 1 are discharged through the discharge port 13, thus completing the degumming of the crude oil. After the degumming is completed, the heat-conducting oil is continuously introduced to heat the crude oil to a suitable temperature for deacidification. The heat-conducting oil continues to enter the heat exchanger 2 to exchange heat with water, and the heat-exchanged water continues to enter the heating device 3 to be heated to a suitable temperature. At this time, an alkaline solution is added to the liquid storage tank 4. The alkaline solution is mixed with the hot water in the branch 51 through the connecting pipeline 5 and then added to the crude oil in the storage tank. At the same time, the stirring assembly 6 stirs. At this time, the free fatty acids in the crude oil form soapstock under the action of acid-base neutralization. After a certain period of time, the stirring is stopped. Subsequently, after a period of settlement, the soapstock settles at the bottom of the refining tank 1, and then the soapstock is discharged through the discharge port 13 to complete the deacidification of the crude oil.
[0038] Preferably, when the refining device in this embodiment performs degumming, the heat-conducting oil heats the temperature of the crude oil to 75°C - 80°C. Within this temperature range, the binding effect between the colloidal impurities in the crude oil and water is the best, and the degumming effect is the best; when performing deacidification, the heat-conducting oil first heats the crude oil to 75°C - 80°C. After adding the alkaline solution and hot water and stirring, the temperature of the crude oil is raised to 90°C. 90°C is the most suitable temperature for the soapstock to separate from the crude oil. Subsequently, maintaining this temperature and performing settlement for a certain period of time can ensure that the soapstock is completely separated; among them, the settlement time during degumming and deacidification needs to be > 5 hours, preferably 6 - 8 hours, which can ensure sufficient settlement and guarantee the degumming and deacidification effects; among them, it should be noted that the above is the preferred solution of this embodiment, and the temperature and settlement time during degumming and deacidification can be specifically adjusted according to the composition, oil volume, solid impurity content, etc. of the crude oil.

The nozzles 152 add the incoming hot water and alkaline liquid to the crude oil in a spraying form, so that it diffuses faster and is more evenly distributed in the crude oil, strengthening the removal effect.
[0040] Please refer to Figure 1 , in this embodiment, a first electromagnetic valve 131 is installed at the discharge port 13, and a second electromagnetic valve 52 and a third electromagnetic valve 53 are respectively installed on the connecting pipeline 5 and the branch pipeline 51.

In addition, by setting the cleaning assembly 7 to perform automatic cleaning work, manual cleaning is not required, effectively saving the cleaning time and reducing the downtime of the device, improving the processing efficiency.
