Problems solved by technology

At present, the production and processing technologies of peanut oil at home and abroad include hot-pressed oil extraction method and cold-pressed oil extraction method. Peanut oil is prepared by low-temperature pressing, but the extraction rate of oil is low, the residual oil rate is high, and the aroma of peanut oil is poor, which makes it difficult to popularize the low-temperature pressing technology

Embodiment 1

[0019] A method for comprehensively and efficiently extracting peanut oil is characterized in that it comprises the following steps:

[0020] (1) Use a peeling machine to remove the peanut shell, and preheat the peanut kernels at a controlled temperature of 65°C for 50 minutes to keep the water content below 4%;

[0021] (2) Cool the peanut kernels to room temperature, remove the red coat with a peeling machine, and crush them into 3-5mm peanut kernels with a granulator;

[0022] (3) Using a screw oil press, the speed of the press is 8r / min, and the temperature is kept at 50°C to obtain preliminary pressed peanut oil and peanut meal;

[0023] (4) Crush the peanut meal to 30 mesh, place it on a steam oven to keep the temperature at 55°C, add water according to the flow rate of 140L / h, adjust the humidity of the billet to 10%, and heat and steam for 15 minutes;

[0024] (5) Heat with 105°C heat conduction oil in the interlayer of the wok, keep the temperature in the wok at 62°C...

Embodiment 2

[0027] A method for comprehensively and efficiently extracting peanut oil is characterized in that it comprises the following steps:

[0028] (1) Use a peeling machine to remove the peanut shell, and preheat the peanut kernels at a controlled temperature of 70°C for 40 minutes to keep the water content below 4%;

[0029] (2) Cool the peanut kernels to room temperature, remove the red coat with a peeling machine, and crush them into 3-5mm peanut kernels with a granulator;

Abstract

The invention discloses a method for extracting peanut oil comprehensively and efficiently. The method is characterized by comprising the following steps: (1) pre-treating peanut; (2) peeling and crushing the peanut; (3) pressing oil by a spiral oil press; (4) smashing and steaming peanut meal; (5) heating and stir-frying; (6) collecting the peanut oil from peanut cake. According to the peanut oil prepared by the method, nutritional ingredients are not damaged; the peanut meal is utilized fully after the oil press; due to the adoption of the adhesion effect principle of the peanut meal, the oil extraction rate of the peanut oilseeds and the quality of peanut oil are improved; moreover, the remaining ingredients can serve as animal feeds. According to the method, by controlling the temperature and increasing the rotation speed of the oil press, quick press can be implemented, the pressing efficiency is improved, the production process is simple and easy to master, and the production cost is low, so that the method has economic benefit.

Description

technical field [0001] The invention relates to the technical field of peanut oil preparation, in particular to a method for comprehensively and efficiently extracting peanut oil. Background technique [0002] The fatty acid composition of peanut oil is relatively good, which is easy for human body to digest and absorb. According to foreign data introduction, use peanut oil, can make cholesterol in human body be decomposed into bile acid and excrete, thereby reduce the content of cholesterol in blood plasma. Go up in addition, in peanut oil, also contain the materials useful to human body such as sterol, wheat germ phenol, phosphatide, vitamin E, choline. Often edible peanut oil, can prevent that wrinkled skin is aging, and protection vascular wall, prevents thrombosis, contributes to prevention of arteriosclerosis and coronary heart disease. Choline in peanut oil can also improve the memory of human brain and delay brain function decline. [0003] In various regions ...
