Description

Technical Field

[0001] The utility model relates to the technical field of oil crystallization processing, in particular to a crystallization tank equipped with an anti-oxidation nitrogen filling device. Background Art

[0002] Domestic fractionation production lines are mainly concentrated in palm oil fractionation; the characteristics of palm oil fractionation are large production design capacity (200-2000 tons / day), rough configuration of production lines and equipment, and huge hidden dangers in food safety and quality assurance. In domestic designs, animal fractionation design will refer to palm oil fractionation design, which will lead to food safety problems and quality fluctuations in 20-50T / D production lines. During the animal oil fractionation process, the oxidation of oil and quality deterioration caused by contact between air and animal oil should be minimized to extend the shelf life of the product. The important equipment for fractionation production is the crystallizer, and the oil should be crystallized in the crystallizer, which takes 800-1100 minutes.

[0003] However, the current fractionation production in the industry is designed with an open atmospheric pressure crystallization tank area. Under this design, the oil will be in contact with the air for a long time during the crystallization process, causing oxidation. At the same time, the residual oil in the crystallization tank is more severely oxidized, making food safety in oil production impossible to guarantee.

[0004] Therefore, those skilled in the art provide a crystallization tank equipped with an anti-oxidation nitrogen filling device to solve the problems raised in the above background technology. Utility Model Content

[0016] Technical effects and advantages of the utility model:

[0017] The utility model adds a nitrogen filling device to the oil inlet pipe of the raw oil. Before the oil is introduced, nitrogen is first used to fill the crystallization tank structure, and then the oil is introduced. After the production is finished, it is ensured that the crystallization tank body is also in a nitrogen-filled state to prevent the residual oil on the tank wall from being oxidized. Such an optimized design can reduce the contact between the raw oil and oxygen, and reduce the oxidation of the oil in the crystallization tank during the crystallization process.

[0018] The utility model increases the nitrogen exhaust port on the crystallizer, and increases the nitrogen sealing valve installed on the outlet, so that the nitrogen exceeding the nitrogen filling pressure in the crystallizer is discharged out of the system through the nitrogen sealing valve, thereby ensuring the stability of the nitrogen filling pressure in the crystallizer.

[0032] Working principle:

[0033] Before the oil is transported into the crystallization tank body 101, the nitrogen is first transported into the crystallization tank body 101 connected to the nitrogen pipe 4 and the oil inlet pipe 109 through the nitrogen inlet pipe 7, and the crystallization tank body 101 is filled with nitrogen. The ball valve 6 is used to close and open the nitrogen inlet pipe 7 and the nitrogen inlet pipe 4, and the check valve 5 prevents the nitrogen in the crystallization tank body 101 from flowing back.

[0034] After nitrogen is filled in the crystallization tank body 101, the ball valve 28 is opened, and the oil in the oil inlet pipe 9 is poured into the crystallization tank body 101 through the oil inlet pipe 3 (the pneumatic ball valve 110 is used to close and open the oil inlet pipe 3 and the oil inlet pipe 109). When the agitator 111 is started, the oil is stirred and processed in the crystallization tank body 101, which can reduce the oxygen solidification of the oil on the inner wall of the crystallization tank body 101, thereby increasing the processing efficiency of the oil;

[0035] The nitrogen inside the crystallization tank 101 is pressurized by the oil entering, passes through the exhaust pipe 108, and is depressurized by the nitrogen sealing valve 10 and discharged into the atmosphere through the chimney filter 11;

[0036] After the oil is processed, the pneumatic butterfly valve 112 is opened to allow the oil to be discharged into the centralized discharge pipe 13 through the discharge pipe 12, and then the oil is pumped out along the delivery pipe 18 through the filter oil pump 15 installed in the centralized discharge pipe 13 for subsequent processing.
