Peanut oil refining production line
The oil extraction method of peanut kernel is beneficial to maintain the inherent flavor and aroma of peanut oil. The pressing method can be divided into ordinary peanut oil production process and strong aroma peanut oil production process. The squeezed peanut cake can be further extracted by solvent extraction to remove most of the remaining oil.

(1) Pre-pressing of peanut kernels - leaching oil extraction process
1. Technological process: pre-pressing of peanut kernels - extraction legal oil, the technological process is as follows:
Peanut kernels → crushing → flaking → steaming → pressing → peanut cake → solvent extraction
Go to further refining ← peanut extraction crude oil ← mixed oil processing
2. Key points of operation: After being crushed by a double-pair roller crusher, each peanut kernel becomes 6-8 pieces of kernel material, and the powder degree is less than 8% (tested by 20 mesh/square inch sieve). The crushed grains are rolled into embryos with a thickness of about 0.5 mm. The raw embryos are steamed and fried to become cooked embryos. When entering the oil press, the water content is 1% - 2%, and the temperature is about 130 degrees. If the cake does not bear the force during pressing and cannot be squeezed into a hard cake, a small amount of peanut shells can be added to the cooked embryo to promote cake formation. ·
Peanut Oil Refining Production Line First press, the squeezed peanut cake can be further solvent leached, and 5-6kg of peanut oil can be extracted per 100kg of dry cake.
(2) Preparation process of Luzhou-flavored peanut oil
1. Process flow: The process flow for preparing Luzhou-flavored peanut oil is as follows:
One piece of peanut kernel → cleaning → picking seeds → crushing → steaming and frying
↓
Erbu peanut kernels → cleaning → picking seeds → roasting → crushing → pressing
↓
Fragrant Peanut Oil ← Filtration ← Crude Oil Precipitation
2. Key points of operation: To produce Luzhou-flavored peanut oil by one-time pressing, it is required to use high-quality newly harvested peanuts to peel the kernels and remove impurities thoroughly. Luzhou-flavored peanut oil is usually not refined, but directly eaten after removing solid impurities. Oil. If the quality of the obtained fragrant peanut oil is poor, it should be refined, but at this time the fragrance of the finished oil will be greatly reduced.
Peanut oil refining production line, the refining process for producing peanut oil
For the pressed peanut oil obtained from high-quality peanut kernels, the refining process should be minimized to retain the original flavor of peanut oil. The peanut crude oil obtained by solvent leaching of peanut cakes should be fully refined. The process of refining extracted peanut crude oil into ordinary peanut oil is the same as that of ordinary soybean oil. The processing of Luzhou-flavored peanut oil is as described above, only need to settle and cold-filter the press-filtered crude oil.
(1) Process flow of peanut oil refining production line
The refining process of high-grade peanut cooking oil and salad oil is as follows:
Low-quality peanut oil—→hydration degumming→alkali refining deacidification→decolorization→deodorization→winterization dewaxing→solid wax

(2) Characteristics of refined oil in peanut oil refining production line
When the peanut oil is at 0-3 degrees, solid fat will solidify and precipitate. To produce peanut salad oil, solid fat components must be removed through winterization, which is the key to producing peanut salad oil. It has been observed that peanut oil obtained from peanut kernels harvested after full maturity has a lighter color. Peanut oil is a good raw material for deep processing of edible oils and fats.
Peanut oil refining production line The refined peanut oil has a high smoke point (229.4°C), which is suitable for high-temperature frying oil.
What is Aroma Peanut Oil? Aroma peanut oil refining production line equipment
Aroma peanut oil is peanut oil with strong fragrance made by special pressing process. It maintains the original composition and fragrance of peanut oil. Because it is rich in antioxidant vitamin E, it does not need to add antioxidants and has a long shelf life. It is a pure original oil produced by combining modern technology with traditional technology.
The cotyledon and germ of peanuts contain high protein, reducing sugar, pentose, sucrose, etc. During the heating process of frying embryos, they can produce Maillard reaction themselves, that is, they can generate aroma substances. There are 17 types and 220 kinds of flavor components produced by roasting peanut kernels. Among them, the high concentration is the viridian compound, which plays a major role in improving the fragrance of peanut oil.
The production of Luzhou-flavored peanut oil requires strict selection of raw materials (peanuts), and the relevant indicators must be higher than the national standard for first-grade peanut oil, and must not contain aflatoxin. Secondly, the production process is also different from ordinary peanut oil, which allows physical and chemical treatments such as hydration, alkali refining, drying, and deodorization during the refining process. In the refining process, Luzhou-flavored peanut oil does not need to undergo the above-mentioned physical and chemical treatments, but adopts a special process of high-temperature short-term frying to produce aroma, one-time pressing, and low-temperature dephosphorization to retain fragrance. Reduces fragrance loss. This is what gives the Aroma Peanut Oil its special rich flavor.
