Problems solved by technology

Different from the pressing method and leaching method, its advantages are mainly that the oil produced has a strong fragrance, simple process equipment, flexible production scale, small investment, convenient small-scale dispersion, flexible operation, no organic solvent residue, relatively green production method, sesame Some trace heavy metal elements in the oil are precipitated in the sesame residue by the water substitution method, and the oil quality is good; but the disadvantages are that the processing is dispersed, the labor productivity is low, the moisture content of the oil sesame residue is high, the sesame residue is easily deteriorated and moldy, and the residual oil rate of the sesame residue is high. High labor intensity, high labor intensity, crude oil needs to stand for a long time, mostly intermittent production, difficult to large-scale production, restricting industrial development
Especially in the stage of blending and stirring oil, artificial stirring is required, the stirring time is long, the amount of water added needs to be controlled empirically, and oil separation is required after stirring and oil extraction. Not only does it need to switch the working power mode, but also the oil temperature decreases during the stage of shaking oil separation. Prolonged oil release time

Embodiment 1

[0021] A method of substituting water for small grinding sesame oil mixed with water to produce oil. The method includes six steps. The first step is raw material screening: impurities in sesame such as soil, sand, iron filings, weed seeds and Immature sesame seeds are removed to obtain qualified sesame raw materials; the second step of raw material rinsing: rinsing the qualified sesame seeds through an automatic washing machine to remove the adherent impurities in the sesame seeds such as side-by-side mud and dust, soaking them in water It takes 60-120 minutes to make the sesame seeds evenly soaked in water and drain. The third step of frying: use the automatic stir-frying wok, start to use high heat, and fry for 15-25 minutes. While stirring, make the sesame seeds cook evenly; after frying, pour cold water about 1-5% of the fried seeds into the pot, and fry for about 1 minute, and take out the pot after the sesame seeds smoke; the fourth step is to raise the smoke Blowing: t...

Embodiment 2

[0024] A kind of water substitution method described in Example 1, the method of mixing small grinding sesame oil with water to produce oil, the sixth step is the preparation of the stirring paddle. According to our exploration, the paddle adopts the form of double-layer paddles: the upper paddle is runoff The shape can be selected from straight blade paddle type or straight blade disc turbine type or three-blade back flap type and other radial flow type stirring paddles, so that during the stirring process, the stirred slurry is in a state of runoff flow, and the lower blades are axial flow Shaped form, choose pusher type or screw ribbon type or screw type or anchor type or frame type or folded blade turbine type equiaxial flow impeller, during the stirring process, the slurry in the lower part can be stirred to the upper part, so that the lower part The slurry can also be fully mixed; the ratio of the size of the paddle to the size of the container is 1:2, and the position of...

Embodiment 3

[0026] A method of water substitution method for small ground sesame oil mixed with water to produce oil described in Example 1, the sixth step is to add water, adding hot water at a temperature of 50-100︒C to the oil slurry, and the way of adding is through the tube Add in at a constant and slow speed, through the hot water pipe, and add in a certain period of time according to the amount of water added, so that the stirring can be ensured to fully mix the oil slurry and water, and the viscosity of the oil slurry can be changed evenly. The whole process will not affect the rotation of the stirring paddle, preventing the rapid increase of viscosity caused by the rapid increase of water and the stoppage of the stirring paddle.

Abstract

The invention discloses a method of a water-extraction-method ground sesame seed oil technology for adding water to extract oil. The method comprises the six steps of (1) screening of a raw material,(2) rinsing of the raw material, (3) stir-frying, (4) blowing off of smoke, (5) grinding, and (6) water adding and stirring: adding hot water into slurry oil obtained through grinding at a low constant speed at once, and completing a high-speed stirring stage, a medium-speed stirring stage, a low-speed stirring stage and an oscillating oil extraction state through a stirring effect of a stirring blade. The method of the water-extraction-method ground sesame seed oil technology for adding the water to extract the oil is used for producing the ground sesame seed oil through a water extraction method.

Description

technical field [0001] The invention relates to a water-substituting method for mixing small ground sesame oil with water to produce oil. Background technique [0002] Sesame is one of the main oil crops in my country. The oil content of the seeds is generally about 53%, and some can reach more than 60%. It has a long history of cultivation, is widely used, rich in various nutrients, and has high medical and nutritional value. Sesame oil extracted from sesame is rich in oleic acid, linoleic acid, palmitic acid, stearic acid and other amino acids needed by humans. The content of unsaturated fatty acids is very high, which has a good effect on lowering serum cholesterol. And sesame oil also contains a variety of biologically active ingredients, such as sesamin, sesamollin, sesamol and other small amounts of natural antioxidants. Due to the presence of these ingredients, sesame oil has good antioxidant stability and a long storage period. . [0003] The preparation methods of...
