Description

Technical Field

[0001] The utility model relates to the technical field of edible oil refining, in particular to a crystallization device for cottonseed oil production. Background Art

[0002] Edible oil refining refers to the process of separating impurities, pigments and odorous substances from raw vegetable oil by physical or chemical methods to make the oil purer, clearer and lighter in taste. Harmful substances in crude oil are removed through processes such as degumming, decolorization, deacidification, deodorization, dewaxing and degreasing. The dewaxing and degreasing processes are to inject the edible oil to be treated into a crystallization tank, inject refrigerant to cool and crystallize it; the high melting point wax and high melting point solid fat in the oil are crystallized and precipitated from the edible oil, and then removed by filtering.

[0003] The traditional degreasing process for edible vegetable oil is mainly used for cottonseed oil. The process is mainly to separate the solid fats near room temperature after cooling. The process is also called winterization process. The edible oil crystallization tank is the main equipment for winterization and fractionation in the refining workshop. It is mainly used for the crystallization and precipitation of high-melting-point substances in oils and fats. Its working principle is mainly to use the different solidification points of wax and oil to crystallize the wax by cooling, and then filter and separate it. Specifically, the oil to be dewaxed in the tank is heat exchanged with the refrigerant through the coil, and the stirring device is constantly stirring to cool the oil in the tank evenly, thereby ensuring that the high-melting-point substances can be crystallized from the oil at an appropriate rate to achieve the purpose of dewaxing.

[0004] The structure of the crystallization device usually consists of a device body, an agitator, a cooling system and a control system. The crystallization device is the main place for the growth of material crystals during the crystallization process. In actual production, the crystallization device often exists in the form of a tank. The cooling system of the crystallization tank mainly includes coils. The coolant is retained in the crystallization tank through a number of coils. Hot oil is introduced into the crystallization tank. The hot oil in the tank contacts a number of coils. The hot oil exchanges heat with the refrigerant in the coils. The wax crystals are precipitated by utilizing the different solidification points of wax and grease. However, in the actual application of the coil, because the coil is often arranged in the tank in a direction parallel to the horizontal plane and perpendicular to the vertical direction of the tank, the number of pipes that can be set is limited by the height of the tank. The number of coils used as cooling liquid pipes is small. Correspondingly, less chilled water is introduced into the cooling liquid pipe, and the contact area between the hot oil and the chilled water is small, resulting in a low degree of heat exchange between the hot oil and the cooling liquid. Utility Model Content

[0005] The utility model aims to provide a crystallization device for cottonseed oil production to solve the problem of low heat exchange between chilled water and hot oil in a tank.

[0006] To achieve the above-mentioned purpose, the basic scheme provided by the utility model is: a crystallization device for cottonseed oil production, comprising a tank body, a driving motor is arranged on the top of the tank body, a rotating shaft is arranged on the output end of the driving motor, the rotating shaft rotates and penetrates the tank body, a stirring blade is arranged on the rotating shaft, an oil inlet pipe is arranged on the bottom of the side of the tank body, an oil outlet pipe is arranged on the bottom of the tank body, a cooling liquid main pipe 1 and a cooling liquid main pipe 2 are arranged in the tank body, the cooling liquid main pipe 1 and the cooling liquid main pipe 2 are respectively located at the bottom and the top of the tank body, a plurality of fixing rods are fixedly connected to the inner wall of the tank body, each fixing rod is fixedly connected to the cooling liquid main pipe 1 and the cooling liquid main pipe 2, a plurality of collecting pipes are connected to the cooling liquid main pipe 1 and the cooling liquid main pipe 2, each collecting pipe is connected to a plurality of cooling liquid straight pipes, a liquid inlet pipe and a liquid outlet pipe are arranged at the bottom of the tank body, the cooling liquid main pipe 1 is respectively connected to the liquid inlet pipe and the liquid outlet pipe, an exhaust port is arranged on the tank body, and four evenly distributed supporting legs are arranged at the bottom of the tank body.

[0007] The principle and beneficial effect of the utility model are as follows: the oil enters the tank body through the oil inlet pipe, and at the same time, chilled water is introduced into a plurality of coolant straight pipes, and the driving motor drives the rotating shaft and the stirring blades to stir, so that the oil in the tank body and the coolant straight pipes are fully in contact, and finally wax crystals are precipitated from the oil; by arranging the coolant pipe as a straight pipe, a coolant main pipe 1 is arranged at the bottom of the tank body, a coolant main pipe 2 is arranged at the top of the tank body, each coolant main pipe is connected to a plurality of collecting pipes, and each collecting pipe is connected to a plurality of coolant straight pipes, in this way, the number of coolant pipes is greatly increased, and the utility model can be used for the production of the following advantages: A high-pressure pump connected to the liquid inlet pipe is used to pressurize the chilled water to the coolant main pipe one, and then the chilled water flows through each coolant straight pipe to the coolant main pipe two. The coolant main pipe, the collecting pipe and the coolant straight pipe are all filled with chilled water. During this period, the high-pressure pump continuously applies pressure to the chilled water in the pipe, so that the pipe is always filled with chilled water. In summary, compared with the coil, in actual applications, more coolant straight pipes can be set in the tank body, and correspondingly more chilled water can be passed in, so that the contact area between the hot oil and the chilled water in the tank is larger, thereby enhancing the heat exchange between the hot oil and the coolant.

[0008] Option 2 is the preferred option of the basic option. Connecting plates are fixed between the stirring blades. The connecting plates between the stirring blades increase the contact area between the hot oil and the stirring blades, thereby increasing the stirring area of ​​the stirring blades, allowing the hot oil to be fully stirred, which is conducive to the precipitation of crystals.

[0009] Option 3 is the preferred option of the basic option. An observation window is provided on the tank body. The setting of the observation port facilitates the operator to observe the internal conditions of the tank body in real time to ensure operational safety and overall crystallization quality.

[0010] Option 4 is the preferred basic option. The tank is equipped with lifting ears. The four lifting ears evenly distributed on the top of the tank side are used to lift and move the crystallization device, which is convenient for operators to use lifting tools (such as slings, hooks, etc.) for lifting operations. When the crystallization device needs to be cleaned, repaired, relocated or moved to another location, the lifting ears can ensure the stability and safety of the crystallization device during the lifting process to avoid accidents.

[0011] Option 5 is the preferred option of the basic option. A reinforcement ring is provided on the outer wall of the tank body. Several reinforcement rings on the outer wall of the tank body can enhance the container's ability to withstand external pressure and prevent the container from deforming or rupturing when subjected to external pressure.
