Problems solved by technology

However, the pressing method is generally high-temperature pressing to make oil. The high temperature severely damages the nutritional components in the oil, which greatly affects the nutritional quality of the product. At the same time, the peanut protein is severely denatured, and the denatured peanut protein cannot be effectively used, resulting At the same time, although many manufacturers use multiple pressings, the operating environment for multiple pressings is the same, and there are defects such as low oil extraction rate and high residual oil rate.

Embodiment 1

[0028] Such as figure 1 Shown, a kind of preparation technology of peanut oil comprises the following steps: material selection-frying-peeling-pressing-skimming-press filtration-precipitation-filling, specifically as follows:

[0029] Use a combination of mechanical and manual methods to remove impurities and defective products in peanut raw materials. Frying is carried out in a spiral electric frying furnace. The frying process adopts two-stage heating to avoid damage to the nutrients in the peanut raw materials. Among them, the temperature of the first stage is controlled at 80 ° C, and the constant temperature is heated for 10 minutes. The temperature is controlled at 100°C, heated at a constant temperature for 15 minutes, and the water content of the peanut raw material is controlled below 3.5%. The roasted peanut raw materials are placed at room temperature, and cooled rapidly by air flow with a temperature of 25°C and a humidity of 40%, so as to avoid the interior of th...

Embodiment 2

[0032] The same part of this embodiment and Embodiment 1 will not be described again, the difference is:

[0033] A preparation process of peanut oil, comprising the following steps: material selection-frying-peeling-pressing-degreasing-press filtration-precipitation-filling, specifically as follows:

[0034] Use a combination of mechanical and manual methods to remove impurities and defective products in peanut raw materials. Frying is carried out in a spiral electric frying furnace. The frying process adopts two-stage heating to avoid damage to the nutrients in the peanut raw materials. Among them, the temperature of the first stage is controlled at 90 ° C, and the constant temperature is heated for 8 minutes. The temperature is controlled at 110°C, heated at a constant temperature for 12 minutes, and the moisture content of the peanut raw material is controlled below 3.5%. The roasted peanut raw materials are placed at room temperature and rapidly cooled by air flow at a t...

Embodiment 3

[0037] The same part of this embodiment and Embodiment 1 will not be described again, the difference is:

[0038] A preparation process of peanut oil, comprising the following steps: material selection-frying-peeling-pressing-degreasing-press filtration-precipitation-filling, specifically as follows:

[0039] Use a combination of mechanical and manual methods to remove impurities and defective products in peanut raw materials. Frying is carried out in a spiral electric frying furnace. The frying process adopts two-stage heating to avoid damage to the nutrients in the peanut raw materials. Among them, the temperature of the first stage is controlled at 100 ° C, and the constant temperature is heated for 5 minutes. The temperature is controlled at 120°C, heated at a constant temperature for 10 minutes, and the water content of the peanut raw material is controlled below 3.5%. The roasted peanut raw materials are placed at room temperature, and cooled rapidly by air flow with a ...

Abstract

The invention relates to a preparation process of peanut oil and belongs to the technical field of plant oil preparation. The preparation process of the peanut oil comprises the following steps of material selection, frying, peeling, squeezing, degreasing, press-filtering, settling and filling. The preparation process of peanut oil combines low-temperature squeezing with sectional intermittent pressurizing, the obtained peanut oil can retain thermosensitive functional active materials, effectively preserve flavor and nutrition of peanuts and improve the quality of the peanut oil; the peanut oil is nutritive, healthful and rich in flavor; after peanuts are fried, low-temperature airflow is applied to accelerating cooling and meanwhile replenishing water content to reduce influence of subsequent hot roller pressing, effectively reduce lecithin content, improve the oil extraction rate, accelerate cooling and meanwhile replenish part of the moisture content, thereby reducing influence of pressing in a heating roller crusher; besides, by combining physical mixing and multiple filtering, the lecithin content can be effectively reduce, and the oil extraction rate can be improved; during preparation, no chemical agent is added, so that good safety and high quality of the peanut oil can be achieved.

Description

technical field [0001] The invention belongs to the technical field of vegetable oil preparation, in particular to a preparation process of peanut oil. Background technique [0002] Peanut is an important oil crop and economic crop in my country. The peanut sowing area in China accounts for 20% of the world's peanut sowing area, while the total output accounts for more than 40% of the world's peanut production, and the peanut export volume accounts for more than 45% of the international peanut trade. Therefore, my country's peanut occupies a pivotal position in the world's peanut production, trade and processing. Peanuts are high in protein and unsaturated fatty acids, rich in vitamins A, B, C, E, etc., and contain Ca, P, Fe, Zn, K and other mineral elements that are beneficial to the human body, especially peanuts The types and quantities of amino acids in protein are rich. The essential amino acids account for 25% of the total amino acids, and the types are complete and re...
