Extracting oil from peanut kernels is beneficial to maintaining the inherent flavor and aroma of peanut oil. The pressing method can be divided into ordinary peanut oil preparation process and concentrated peanut oil preparation process. After pressing the peanut cake, a solvent leaching method can be further used to remove most of the remaining fat.

(I) Pre-pressing of peanut kernels-oil extraction process by leaching
1. Process flow: Pre-pressing of peanut kernels-leaching method to make oil, the process flow is as follows:
Peanut kernels → Broken → Rolled embryos → Steaming → Pressing → Peanut cakes → Solvent extraction
Peanut hair oil ← Filtration ← Peanut press hair oil
Go for further refining ← Peanut extract oil ← Mixed oil treatment
2. Main points of operation: After being crushed by a double-roller crusher, each peanut kernel becomes 6-8 petals, and the degree of powder is less than 8% (20 mesh / square inch sieve inspection). The crushed grains are rolled into embryos with a thickness of about 0.5 mm. The raw embryos become cooked embryos after being processed in a steaming wok. The moisture when entering the oil press is 1%-2%, and the temperature is about 130 degrees. If the cake does not bear the load when pressed, and does not make a hard cake, a small amount of peanut shell can be added to the cooked embryo to promote cake formation.
The pressed peanut cake can be further subjected to solvent extraction, and 5-6 kg of peanut oil can be extracted per 100 kg of dry cake.
(II) Preparation process of strong fragrant peanut oil
1. Process flow: The process of preparing Luzhou-flavored peanut oil is as follows:
One peanut kernel → clean up → picking seeds → broken → steamed
Two peanut kernels → clean up → picking seeds → roasting processing → crushing → pressing
Luscious Peanut Oil ← Filtration ← Hair Oil Precipitation
2. Key points of operation: The production of luscious peanut oil by one-press method requires the use of high-quality freshly harvested peanuts and peeled kernels. The impurities must be clean and thorough. Luscious peanut oil is usually not refined, but is directly consumed after removing solid impurities oil. If the luscious peanut oil obtained is of poor quality, it should be refined, but at this time the aroma of the refined oil will be greatly reduced.
Second, the refining process of peanut oil For pressed peanut oil obtained from high-quality peanut kernels, the refining processing steps should be minimized to retain the original flavor of peanut oil. The peanut oil obtained by solvent extraction of peanut cake should be fully refined. The process of refining the leached peanut 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, and it is only necessary to settle and filter cold filter oil.
(1) Process flow The refining process of high-grade peanut cooking oil and salad oil is as follows:
Low quality peanut oil —
| → Hydration degumming → Alkali refining deacidification → Decoloration → Deodorization → Winter dewaxing → Solid wax Peanut dipping— ↓ ↓
Hair oil, high-grade cooking oil, peanut salad oil products
(2) Key to production and characteristics of refined oil Peanut oil solidifies and precipitates at 0-3 degrees. To produce peanut salad oil, you must remove the solid fat component through winterization, which is the key to producing peanut salad oil. It has been observed that the peanut oil obtained from peanut kernels harvested after full maturity has a lighter color. Peanut oil is a good raw material for the preparation of edible oil processed products.
The refined peanut oil has a high smoke point (229.4 ° C) and is suitable for high-temperature frying oil.
