Embodiment 1

[0020] A cottonseed alkaline treatment oil extraction process, the preparation steps are as follows:

[0021] 1) Screening: Screen out the finished cottonseed products that have been processed and removed from the shell;

[0022] 2) Softening: Send the screened cotton seeds into the softening box for softening and soften them twice. The first softening temperature is 60°C, and the softening time is 10 minutes. The second softening temperature is 70°C, and the softening time is 10 minutes. 10min;

[0023] 3) Embryo tying: the softened cottonseed is subjected to embryo tying, and the cottonseed is changed from granular to oval;

[0024] 4) Steaming and frying: send the softened cottonseed into a steaming and frying pan for steaming and frying, wherein the steaming and frying process is divided into three steps of steaming and frying, the temperature of the first step of steaming and frying is 85°C, and the steaming and frying time is 10min, The temperature of the second step o...

Abstract

The invention discloses a cotton seed alkali treatment oil pressing technology. The oil pressing technology comprises the steps of screening, softening, embryo rolling, cooking, oil pressing, oil refining, separating and drying, and finished cotton seed oil is obtained, wherein refined oil is separated, then obtained semi-product oil is dried and then subjected to deodorization to remove peculiar smells, then collecting is carried out, and the finished product is obtained. The oil pressing technology is simple and low in production cost, and obtained finished product oil is pure in oil aroma, bright in color, harmless to the human body, long in storage life and not likely to go bad.

Description

technical field [0001] The invention relates to the technical field of oil extraction, in particular to an alkaline oil extraction process of cottonseed. Background technique [0002] Cottonseed oil is the oil squeezed from cotton seeds. The refined cottonseed oil is generally orange-yellow or brown. The fatty acid contains 21.6-24.8% palmitic acid, 1.9-2.4% stearic acid, 0-0.1% arachidic acid, and 18.0- oleic acid. 30.7%, linoleic acid 44.9-55.0%, the refined cotton oil has removed toxic substances such as gossypol, and can be eaten by humans. Cottonseed oil contains a large amount of essential fatty acids, and it is most suitable to be eaten mixed with animal fat, because the content of linoleic acid in cottonseed oil is particularly high, which can effectively inhibit the rise of cholesterol in the blood and maintain human health. [0003] However, the current cottonseed oil refining process is complicated, the refining effect is not good, and the obtained product oil is...
