Description

Technical Field

[0001] The utility model relates to the field of vegetable oil production, in particular to a vegetable oil winterization device. Background Art

[0002] Winterization is a crystallization separation method, which is a process of cooling oils and fats, crystallizing glycerides with higher freezing points, and separating oils and impurities such as solid fats. After winterization, vegetable oils become clearer, and edible oils can maintain transparency and fluidity in the refrigerator after winterization. When winterizing vegetable oils using some existing winterization devices, in the process of cooling the vegetable oils and keeping them at a low temperature, the stirring mechanism is used to stir at a low speed so that the temperature of each part of the vegetable oil is evenly cooled, and the crystallized solid oils precipitated by cooling can settle to the bottom of the winterization device, so that the glycerides with higher freezing points are separated and gathered at the bottom of the winterization device.

[0003] However, during the precipitation process of glycerides with a higher freezing point, because the stirring mechanism is always in a rotating state, the stirring mechanism will stir the precipitated glycerides to the upper side, and it is difficult for the solid glycerides to always settle and accumulate in the lower area of ​​the winterization device, which undoubtedly affects the final winterization effect. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a vegetable oil winterization device to solve the problem that the stirring mechanism of some existing winterization devices stirs the precipitated glyceride up again, affecting the winterization effect.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions.

[0006] The utility model provides a vegetable oil winterization device, comprising a tank body and a tank cover, wherein the tank cover is movably mounted on the top of the tank body, a spiral coil is arranged in the tank body in the vertical direction, a liquid inlet pipe and a liquid outlet pipe are arranged on the side wall of the tank body, the liquid inlet pipe and the liquid outlet pipe are respectively connected to the upper and lower ends of the coil, a lower frame is arranged at the lower part of the tank body, a rotating shaft is arranged between the tank cover and the lower frame, a plurality of stirring rods are arranged on the surface of the rotating shaft, and the coil is located outside the stirring rod;

[0007] A filter plate is horizontally arranged in the tank body, and the filter plate is located below the lower frame. Filter channels are evenly arranged on the filter plate, and the upper section of the filter channel is vertical, the middle section is inclined, and the lower section is vertical.

[0008] Preferably, a reducer is provided on the top of the tank cover, the reducer is transmission-connected to the motor, and the reducer is transmission-connected to the rotating shaft.

[0009] Preferably, a plurality of fixing frames are provided on the inner wall of the tank body, and one end of the fixing frame away from the tank body is fixed on the coil.

[0010] Preferably, the central axis of the tank body and the central axis of the coil are located on the vertical axis of the rotating shaft.

[0011] Preferably, the distance between the stirring rod and the coil is not less than the cross-sectional diameter of the coil.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The solid glyceride precipitated during the cooling process can enter the tank space below the filter plate through the filter channel and gather in this area; during the stirring process of the stirring rod, the solid glyceride below the filter plate is difficult to float up through the filter channel and no longer enters the upper liquid vegetable oil. Finally, the content of high-freezing-point glyceride in the winterized vegetable oil is lower, and the quality of the winterized vegetable oil is better, which solves the problem that the stirring mechanism of some existing winterization devices stirs the precipitated glyceride again and affects the winterization effect.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-4As shown, a vegetable oil winterization device includes a tank body 1 and a tank cover 2. A reducer 21 is arranged on the top of the tank cover 2. The reducer 21 is connected to a motor 22 in a transmission manner. The reducer 21 is connected to a rotating shaft 23 in a transmission manner. The motor 22 drives the rotating shaft 23 to rotate at a low speed.

[0021] The tank cover 2 is movably mounted on the top of the tank body 1. A spiral coil 14 is arranged in the tank body 1 in the vertical direction. The central axis of the tank body 1 and the central axis of the coil 14 are located on the vertical axis of the rotating shaft 23. A plurality of fixing frames 13 are arranged on the inner wall of the tank body 1. One end of the fixing frame 13 away from the tank body 1 is fixed on the coil 14. The fixing frame 13 supports and fixes the coil 14 to ensure the stability of the coil 14. The coolant flows in the coil 14 to cool the vegetable oil in the tank body 1. The distance between the stirring rod 24 and the coil 14 is not less than the cross-sectional diameter of the coil 14.

[0022] The side wall of the tank body 1 is provided with a liquid inlet pipe 12 and a liquid outlet pipe 11, which are connected to the upper and lower ends of the coil 14 respectively. The coolant flows into the coil 14 from the liquid inlet pipe 12 and then flows out from the liquid outlet pipe 11. A lower frame 15 is provided at the lower part of the tank body 1. A rotating shaft 23 is provided between the tank cover 2 and the lower frame 15. The tank cover 2 and the lower frame 15 support the rotating shaft 23. A plurality of stirring rods 24 are provided on the surface of the rotating shaft 23. The coil 14 is located outside the stirring rod 24. The stirring rod 24 stirs the vegetable oil to evenly cool the vegetable oil.

[0023] A filter plate 3 is horizontally arranged in the tank body 1, and the filter plate 3 is located below the lower frame 15. Filter channels 31 are evenly arranged on the filter plate 3. In the process of cooling the vegetable oil and maintaining the low temperature, the precipitated solid glyceride can enter the space of the tank body 1 below the filter plate 3 through the filter channel 31; the upper section of the filter channel 31 is vertical, the middle section is inclined, and the lower section is vertical. This trend of the cross-section of the filter channel 31 can prevent the solid glyceride already in the space of the tank body 1 below the filter plate 3 from floating up again and flowing back through the filter channel 31 to the space of the tank body 1 above the filter plate 3.

[0024] Working principle: The coolant is sent into the coil 14 through the liquid inlet pipe 12. During the flow of the coolant, the heat of the vegetable oil in the tank body 1 is taken away. The stirring rod 24 rotates at a low speed to evenly cool the vegetable oil. In the process of cooling the vegetable oil and maintaining it at a relatively low temperature, the glyceride with a higher freezing point solidifies into a solid. Under the action of its own weight, it slowly passes through the filter channel 31 into the lower area of ​​the tank body 1; the stirring rod 24 always stirs at a low speed, and the solid glyceride that is already below the filter plate 3 is difficult to float to the area above the filter plate 3 through the filter channel 31. After winterization, the glyceride with a lower freezing point above the filter plate 3 has a higher purity and better quality.
