Embodiment 1

[0024] The corn oil dewaxing process comprises the steps:

[0025] (1) Send the degummed and dried oil into the dewaxed oil tank, pump the oil through the heat exchanger to lower the oil temperature to 40°C, and then send it into the crystallization tank;

[0026] (2) Number the crystallization tanks sequentially, and fill in oil in order, and then fill in the next tank after the previous tank is full;

[0027] (3) Turn on the refrigeration unit in advance, maintain the circulating refrigerant at about -5°C, open all the inner and outer coil valves of the crystallization tank, and perform system circulation. When the oil in the crystallization tank is full, cool down by 1 hour per hour Slowly lower the temperature at ℃, and stir with a stirrer for 3 minutes every 20 minutes. When the temperature of the crystallization tank drops to 16 ℃ and solid wax is fully separated from the oil, stop stirring, and keep the crystallization for 48 hours;

[0028] (4) According to the princi...

Embodiment 2

[0031] The corn oil dewaxing process comprises the steps:

[0032] (1) Send the degummed and dried oil into the dewaxed oil tank, pump the oil through the heat exchanger to lower the oil temperature to 60°C, and then send it into the crystallization tank;

[0033] (2) Number the crystallization tanks sequentially, and fill in oil in order, and then fill in the next tank after the previous tank is full;

[0034] (3) Turn on the refrigeration unit in advance, maintain the circulating refrigerant at about 10°C, open all the inner and outer coil valves of the crystallization tank, and perform system circulation. When the oil in the crystallization tank is full, cool down by 1.5°C per hour Slowly lower the temperature at a certain speed, and use a stirrer to stir for 5 minutes every 30 minutes. When the temperature of the crystallization tank drops to 17°C and solid wax is fully separated from the oil, stop stirring, and keep the crystallization for 72 hours;

[0035] (4) Accordin...

Embodiment 3

[0038] The corn oil dewaxing process comprises the steps:

[0039] (1) Send the degummed and dried oil into the dewaxed oil tank, pump the oil through the heat exchanger to lower the oil temperature to 50°C, and then send it into the crystallization tank;

[0040] (2) Number the crystallization tanks sequentially, and fill in oil in order, and then fill in the next tank after the previous tank is full;

[0041] (3) Turn on the refrigeration unit in advance, maintain the circulating refrigerant at about 5°C, open all the inner and outer coil valves of the crystallization tank, and perform system circulation. When the oil in the crystallization tank is full, lower the temperature by 1.2°C per hour Slowly lower the temperature at a high speed, and use a stirrer to stir for 4 minutes every 25 minutes. When the temperature of the crystallization tank drops to 16.5°C and solid wax is fully separated from the oil, stop stirring, and keep warm and crystallize for 65 hours;

Abstract

The invention discloses a dewaxing technique for maize oil. According to the dewaxing technique, the maize oil is cooled to separate out crystal wax by reasonably controlling the cooling process of the maize oil; no chemical substances are added in the process, so that greenness and environmental protection are realized; in addition, the separated crystal wax is relatively sufficient and are filtered to reach the dewaxing effect of the maize oil; no workers are needed in the whole process; and the dewaxing technique has the advantages of low labor intensity, high efficiency and good dewaxing effect.

Description

technical field [0001] The invention belongs to the field of food processing and manufacturing, and in particular relates to a corn oil dewaxing process. Background technique [0002] Corn oil contains oryzanol alone, and the vitamin E content is much higher than other edible oils. In addition, corn oil has a higher smoke point. Compared with other household oil products, frying oil has a little less smoke and is healthier. The content of saturated fatty acid per 100 grams of corn oil is 23.2, the content of monounsaturated fatty acid is 42.2, and the content of polyunsaturated fatty acid is 34.5, the ratio is close to 1:1:1, which is close to the standard recommended by the World Nutrition Association. It is a high-quality natural Healthy Oils. However, corn crude oil has a very high wax content of 1%-5%. In the oil making process, the wax is difficult to remove, which affects the transparency and taste of the refined corn oil. Contents of the invention [0003] The tec...
