Description

Technical Field

[0001] The utility model relates to the technical field of rapeseed oil processing, in particular to a rapeseed oil decolorization device. Background Art

[0002] Rapeseed oil is a transparent or translucent liquid obtained by squeezing the seeds of the cruciferous plant Brassica rapa (i.e. rapeseed). In order to remove unwanted byproducts in the oil, including certain harmful substances that are not conducive to food safety and hygiene, such as polycyclic aromatic hydrocarbons caused by pollution, pesticide residues, oxidative deterioration substances, etc., decolorizing agents are added to the rapeseed oil for decolorization.

[0003] When the rapeseed oil and the decolorizing agent are stirred and mixed, the decolorizing agent is directly added to the rapeseed oil and stirred by rotating the stirring rod so that the decolorizing agent can adhere to the rapeseed oil for decolorization. However, this processing method has the following shortcomings when used: the rapeseed oil is not filtered before decolorization, which makes it difficult to remove impurities and rapeseed shells in the rapeseed oil, and the impurities remaining in the rapeseed oil will affect the cleanliness of the rapeseed oil; when the stirring rod is stirring the rapeseed oil, the decolorizing agent is very likely to come into contact with the upper layer of the rapeseed oil, making it difficult for the decolorizing agent to adhere to the bottom layer of the rapeseed oil, making it difficult for the decolorizing agent to fully adhere to the rapeseed oil, thereby affecting the decolorization efficiency of the rapeseed oil.

DETAILED DESCRIPTION

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Referring to Figure 1-Figure 3 , a rapeseed oil decolorization device, including a stirring tank 1, in which a filter screen 2 that divides the stirring tank 1 into an upper cavity and a lower cavity is fixedly installed. By setting the filter screen 2 in the stirring tank 1, rapeseeds can fall evenly.

[0021] An upper cavity is equipped with a filtering component for filtering rapeseeds.

[0022] The filtering component includes two support plates 3 provided in the upper cavity. A moving rod 4 is slidably sleeved on the support plates 3. A connecting plate 5 and a moving plate 6 are fixedly installed on the moving rod 4. A filter frame 8 for filtering rapeseeds is integrally connected between the two moving plates 6. The support plates 3 play a guiding role for the moving rod 4, enabling the moving rod 4 to smoothly pull the connecting plate 5 and the moving plate 6 during movement. The spring 7 can prevent the connecting plate 5 from directly impacting the support plates 3, thereby ensuring the stability of the filter frame 8. A spring 7 cooperating with the moving rod 4 is welded between the connecting plate 5 and the support plates 3.

[0023] The moving rod 4 is vertically arranged on both sides of the filter frame 8. The connecting plate 5 and the moving rod 4 extend to the upper end position outside the support plates 3. The spring 7 is sleeved on the moving rod 4. The moving plate 6 and the moving rod 4 extend to the lower end position outside the support plates 3. A connecting frame 9 is fixedly installed on the connecting plate 5. An expansion rod 10 connected to the connecting frame 9 is installed on the stirring tank 1. The connecting frame 9 is of a U-shaped structure. The reciprocating movement of the connecting frame 9 is driven by the expansion and contraction of the output end of the expansion rod 10. The connecting frame 9带动 the moving rod 4 and the moving plate 6 to move synchronously through the connecting plate 5, and the moving plate 6带动 the filter frame 8 to move reciprocally, thereby realizing dynamic filtering of rapeseeds. By filtering rapeseeds, soil clods and rapeseed husks in the rapeseeds can be intercepted, thereby ensuring the cleanliness of rapeseeds.

[0024] A lower cavity is equipped with a stirring component for stirring rapeseeds.

[0025] The stirring component includes a motor 11 fixedly installed on the filter screen 2. The output end of the motor 11 is fixedly connected with a rotating shaft 12. A sleeve 13 for storing a decolorizing agent is connected to the rotating shaft 12. A stirring rod 14 for stirring rapeseeds is integrally connected to the sleeve 13. After the motor 11 is powered on, it drives the rotating shaft 12 to rotate. This technical solution is an existing technology and will not be elaborated here too much. The stirring rod 14 can stir rapeseeds during rotation.

[0026] The stirring rod 14 is provided with evenly distributed through holes 15 for discharging the decolorant. A delivery pipe 16 corresponding to the through holes 15 is installed in the stirring rod 14, and a connecting pipe 17 is connected between the delivery pipe 16 and the sleeve 13. The rotating shaft 12 is arranged vertically, and the sleeve 13 is provided with a bolt that matches the rotating shaft 12. The stirring rod 14 is arranged horizontally. When the decolorant needs to be stored, the sleeve 13 is removed from the rotating shaft 12, and the decolorant is delivered to the sleeve 13. When the stirring rod 14 rotates, it can drive the delivery pipe 16 to rotate synchronously, and then the decolorant is delivered through the connecting pipe 17, so that the decolorant can be discharged into the rapeseed through the through holes 15. Through multiple through holes 15 with openings facing downwards, the decolorant can fully contact with the rapeseed when discharged, further improving the efficiency of mixing the rapeseed and the decolorant.

[0027] The functional principle of this utility model can be explained through the following operation modes:

[0028] Put rapeseed into the filter frame 8;

[0029] The output end of the telescopic rod 10 is telescopically driven to move the connecting frame 9 up and down, and the connecting frame 9 drives the connecting plate 5 to move synchronously. The connecting plate 5 drives the moving rod 4 to slide on the support plate 3. The spring 7 is stressed, and the moving rod 4 drives the moving plate 6 to slide in the upper cavity. The two moving plates 6 drive the filter frame 8 to move up and down, thereby dynamically filtering the rapeseed. The filter frame 8 can initially filter the rapeseed, and the filter screen 2 can filter the rapeseed in the filter frame 8 again, so that the rapeseed falls evenly.

[0030] After the rapeseed is filtered, it falls into the lower chamber. The output end of the motor 11 drives the rotating shaft 12 and the sleeve 13 to rotate. When the sleeve 13 rotates, it drives the stirring rod 14 to stir the rapeseed.

[0031] The decolorant in the sleeve 13 is transported to the delivery pipe 16 through the connecting pipe 17, and the decolorant in the delivery pipe 16 is discharged into the rapeseed through the through hole 15;

[0032] After the rapeseed and the decolorizing agent are mixed for a certain period of time, the rapeseed is discharged from the mixing box 1 .

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
