Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0020] see figure 1 , the present invention provides a technical solution: a method for pressing rapeseed oil with high conversion rate, the specific steps of the method are as follows:

[0021] S1: Select fresh rapeseed without mildew and no peculiar smell, put it into 3% boiling water, stir evenly, let it stand for stratification, soak for 20-30min, remove and drain, and use a screening machine to remove the inclusions in the rapeseed , the erucic acid cont...

Abstract

The invention discloses a rapeseed oil squeezing method with a high conversion ratio and belongs to the technical field of vegetable oil squeezing. The method comprises the following specific steps: S1: raw material cleaning; S2: high-temperature frying; S3: grinding blank forming; S4: blank steaming treatment; S5: oil material squeezing; S6: deacidification of fats and oils; and S7: static settlement. According to the method, prior to oil squeezing, oil materials are firstly cleaned and crushed and then are subjected to high-temperature heat treatment, thus, interior of the oil materials canbe subjected to a series of changes such as destruction of oil material cells, prompting of protein denaturation and lowering of viscosity of the fats and oils so as to be applicable to squeezed oil squeezing and oil yield increase, unsaturated fatty acids such as linoleic acid in the fats and oils are not destroyed, nutritional ingredients and natural flavors of crude oil in oil-bearing crops arereserved, and chemical residual is absent.

Description

technical field [0001] The invention discloses a method for pressing rapeseed oil with high conversion rate, and specifically belongs to the technical field of vegetable oil pressing. Background technique [0002] In addition to mainly containing triglycerides, rapeseed oil also contains tocopherols and phospholipids. Trace elements such as pigments and free fatty acids, most rural areas have a tradition of eating rapeseed oil. Every May, when the rapeseed is harvested, people squeeze the freshly harvested rapeseed to get fresh rapeseed oil for consumption. However, most of the small-scale pressing workshops adopt the local method of pressing, the oil conversion rate of the rapeseed oil is low, the quality stability of the rapeseed oil is poor, and the taste of the pressed rapeseed oil is not good. For this reason, we put forward a high-conversion rapeseed oil pressing method and put it into use to solve the above problems. Contents of the invention [0003] The object o...
