Problems solved by technology

[0004] In the production process of peanut oil, a peanut oil steamer is needed. The heat control is not exquisite enough, and the denaturation of the material is not appropriate, especially the upper material, which is not heated enough. This will inevitably lead to unstable product quality and the oil yield of the material in the next stage. Reduced, and the taste is not good, the color is not bright enough, and the heating is too high, the energy consumed for making peanut oil is large, and the cost increases

Embodiment 1

[0015] An improved method for steaming peanut embryos with high oil yield, characterized in that it comprises the following steps:

[0016] (1) Embryo pressing: Peanut kernels crushed to 3mm are rolled into fine grains of 0.5mm by adjusting the gap between the rollers;

[0017] (2) Embryo steaming: spread the above-mentioned green body evenly in the steamer, raise the material layer in the steamer to 75cm, then control the temperature at 100°C, steam the embryo for 70min, and control the moisture content to 4.5%;

[0018] (3) Embryo frying and pressing: control the temperature at 115°C, fry the embryos for 15 minutes, control the stirring speed at 40 rpm, control the water content at 2% after frying the embryos, and naturally squeeze crude oil, and the oil yield of peanuts can reach 90%. .

Embodiment 2

[0020] An improved method for steaming peanut embryos with high oil yield, characterized in that it comprises the following steps:

[0021] (1) Embryo pressing: Peanut kernels crushed to 3mm are rolled into fine grains of 0.5mm by adjusting the gap between the rollers;

[0022] (2) Embryo steaming: spread the above-mentioned green bodies evenly in the steamer, raise the material layer in the steamer to 80cm, control the temperature at 110°C, steam the embryos for 65min, and control the moisture content to 4.5%;

[0023] (3) Embryo frying and pressing: control the temperature at 115°C, fry the embryos for 15 minutes, control the stirring speed at 40 rpm, control the water content at 3% after frying the embryos, and naturally squeeze crude oil, and the oil yield of peanuts can reach 93.5% .

Embodiment 3

[0025] An improved method for steaming peanut embryos with high oil yield, characterized in that it comprises the following steps:

[0026] (1) Embryo pressing: Peanut kernels crushed to 3mm are rolled into fine grains of 0.5mm by adjusting the gap between the rollers;

[0027] (2) Embryo steaming: spread the above-mentioned green body evenly in the steamer, raise the material layer in the steamer to 85cm, then control the temperature at 120°C, steam the embryo for 60min, and control the moisture content to 4.5%;

[0028] (3) Embryo frying and pressing: control the temperature at 115°C, fry the embryos for 15 minutes, control the stirring speed at 40 rpm, control the water content at 3% after frying the embryos, and naturally squeeze crude oil, and the oil yield of peanuts can reach 91%. .

Abstract

The invention discloses an improved method for steaming peanut embryos with high oil yield, which is characterized in that it comprises the following steps: (1) embryo pressing (2) raising the material layer in the steamer to steam embryos (3) frying embryos press. The present invention improves the thickness of the material layer in the steamer, controls the temperature properly, heats the raw materials better, makes the moisture of the steamed embryo penetrate thoroughly, improves the product stability and the oil yield of raw materials, and has the advantages of saving energy and reducing consumption. The extracted peanut oil has strong fragrance, transparent and bright color, and good taste.

Description

technical field [0001] The invention belongs to the technical field of peanut oil pressing, and in particular relates to an improved method for steaming peanut embryos with high oil yield. Background technique [0002] Peanut oil is light yellow and transparent, with clear color, fragrant smell and delicious taste. It is a kind of edible oil that is relatively easy to digest. Peanut oil contains more than 80% unsaturated fatty acids (including 41.2% oleic acid and 37.6% linoleic acid). In addition, it also contains 19.9% ​​of saturated fatty acids such as palmitic acid, stearic acid and arachidic acid. The fatty acid composition of peanut oil is relatively good, which is easy for human body to digest and absorb. [0003] There are many ways to prepare peanut oil, and there are two commonly used methods: one is frying seed machine pressing, the process includes putting peanut kernels into a drum wok and directly heating and frying, the temperature is about 500 ℃, and then, ...
