Embodiment 1

[0011] Put the peanut kernels in a low-temperature wok, steam and fry for 36 minutes, quickly air-cooled after being out of the pan, and use a stripper to quickly undress, the undressing rate is 95%.

[0012] The undressed peanut kernels are pressed by a 4.5MPa screw press to extract 16Kg of oil, and the extracted crude oil becomes edible peanut oil after pressure filtration, hydration degumming, centrifugal removal and other processes.

[0013] Put 2kg of peanut powder after partial extraction of oil into 8kg of 0.5% NaHCO at 40℃ 3 Soak in the solution for 3 hours.

[0014] The soaking liquid is filtered out, and the peanut powder is mixed with 20Kg of water using a colloid mill, repulsed twice, passed through a 100-mesh sieve, and the slurry residue is separated. Control the refining temperature at 75~80℃.

[0015] Mix 36g carrageenan, 36g molecularly distilled monoglyceride, 36g sucrose fat, and 2.7kg white sugar, and dissolve them in 16Kg 96°C hot water, keep the temperature a...

Embodiment 2

[0019] Put the peanut kernels in a low-temperature wok and steam them for 39 minutes. After they are out of the pan, the peanuts are quickly air-cooled. The undressing machine is used to quickly undress the undressing rate.

[0020] The undressed peanut kernels are subjected to a 3.0MPa screw press to extract 15Kg of oil, and the extracted crude oil becomes edible peanut oil after pressure filtration, hydration degumming, centrifugal removal and other processes.

[0021] Put 3kg of peanut powder after partial extraction of oil into 15kg of 0.5% NaHCO at 40℃ 3 Soak in the solution for 2.5 hours.

[0022] The soaking liquid is filtered out, and the peanut powder is mixed with 30Kg of water by a colloid mill, and the recirculation refining is performed twice, and the slurry is separated through a 150-mesh sieve. Control the refining temperature at 80~85℃.

[0023] Mix 27g of agar, 108g of molecularly distilled monoglyceride, 54g of sucrose fat, and 4.32kg of white granulated sugar, d...

Embodiment 3

[0027] Put the peanut kernels in a low-temperature wok, steam and fry for 40 minutes, quickly air-cooled after being out of the pan, and use a stripper to quickly undress, the undressing rate is 98.5%.

[0028] The undressed peanut kernels are subjected to a pressure of 8.0MPa to extract 17Kg of oil by a screw press, and the extracted crude oil becomes edible peanut oil after pressure filtration, hydration degumming, centrifugal removal and other processes.

[0029] Put 3kg of peanut powder after partial extraction of oil into 15kg of 0.5% NaHCO at 50℃ 3 Soak in the solution for 3 hours.

[0030] The soaking liquid is filtered out, the peanut powder is mixed with 36Kg of water using a colloid mill, and the recirculation is repulsed twice, and the slurry is separated through a 300-mesh sieve. Control the refining temperature at 75~85℃.

[0031] Mix 54g of agar, 54g of xanthan gum, 54g of molecularly distilled monoglyceride, 54g of sucrose fat, and 3.24kg of white granulated sugar, ...

Abstract

A method for continuously extracting out peanut oil and protein includes steaming and frying peanuts, shelling and degreasing to obtain peanut powder; soaking the powder and grinding it for thick liquid; adding emulsification stabilizer and sugar into hot water; emulsifying it with colloidal mill and mixing it with thick liquid for preparing peanut milk through homogenizing, sterilizing and packing; and obtianing peanut oil by carrying out filter pressing, water degumming and centrifugal decontaminating for degreased and expressed crude oil.

Description

Technical field [0001] The invention relates to the technical field of extracting oil and protein from peanuts as raw materials, in particular to a preparation method for continuously extracting peanut oil and protein. Background technique [0002] At present, peanuts are generally used to extract oil, or to make peanut powder after extracting oil, or to make peanut milk without defatting. The peanut powder directly extracted from the oil is generally used as feed, resulting in a great waste of peanut protein. The peanut milk made without skimming has the disadvantages of oil floating and poor stability. Therefore, in the extraction process of peanut protein, there is an urgent need for a technology that can not only extract oil effectively, but also maximize the use of peanut protein, so as to achieve the purpose of making full use of peanut resources. But so far, there is no report of related technology. Summary of the inventio...
