Abstract
The invention discloses a rapeseed oil production process and belongs to the production field of the edible oils. The rapeseed oil production process comprises the following steps: a, preparing raw materials; b, preparing a crude oil, namely evenly spraying deionized water accounting for 3-5% of the raw materials to the raw materials at first, secondly, crushing the raw materials, and then putting the raw materials into a stir pan, heating the stir pan by firing coal, and continuously stirring the crushed raw materials in the stir pan in the heating process; after the stir pan is heated to the range of 100-105 DEG C, immediately putting the crushed raw materials in the stir pan into a squeezer for squeezing, and collecting the liquid, namely the crude oil; c, refining the crude oil, namely heating the crude oil, removing phospholipid and acid interface, and filtering to obtain the finished product. If the rapeseed oil production process is applied to producing the rapeseed oil, firstly, the produced rapeseed oil is high in purity and good in taste, and the beneficial ingredients in the rapeseed are not damaged; secondly, the oil yield of the rapeseeds is increased by virtue of the production process, and the cost of an enterprise can be saved.
Description
Technical field
The present invention relates to edible fat production field, be specifically related to a kind of rapeseed oil production technique.
Background technology
Rapeseed oil is exactly the rape oil that we are commonly called as, and being again caraway oil, is the liquid of the transparent or semitransparent shape pressing gained with the seed of cress rape (i.e. rape).The specific absorption of human body to rapeseed oil is high, can reach 99%.Effect that rapeseed oil also has certain vessel softening, delays senility; Meanwhile, the raw material due to squeezing rapeseed oil is that the kind of plant is real, and it also can contain certain seed phosphatide, very important to the growth of blood vessel, nerve, brain; In addition, the cholesterol of rapeseed oil seldom or hardly contains, so the people controlling cholesterol intake can relievedly eat.Because rapeseed oil has above-mentioned many benefits, it becomes one of China's main edible oil, and the main place of production is the Yangtze valley and the ground such as southwest, northwest, and output occupies first place in the world.
In prior art, the making processes of rapeseed oil is steamed stir-fry, pre-squeezing for clearing up, softening, roll embryo, is leached.Owing to rolling in embryo steaming stir-fry, temperature is higher, and the rapeseed oil crude oil born is comparatively dark, and impurity is more, and acid value is higher, reduces the rate of output of treated oil; Also destroy the protein in dregs of rapeseed cake simultaneously, and cause amino acid such as Gelucystine, methionine(Met), phenylalanine, tyrosine, α-amino-isovaleric acid equal size first mate to decline, especially the first limiting amino acids---Methionin considerable damage, reduces the feeding quality of rapeseed meal.Further, in prior art, the rate of output of rapeseed oil is not high yet, greatly wastes the resources of production, reduces the profit of enterprise.
Summary of the invention
For above the deficiencies in the prior art, the invention provides a kind of rapeseed oil production technique, comprise the steps:
The preparation of a, raw material: by removing impurities of rapeseeds, clean up after, being dried water content is 1 ~ 2%, obtains raw material;
The preparation of b, crude oil: described raw material, first evenly spraying into quality is its deionized water of 3 ~ 5%, then that it is broken, then inserts in frying pan, then heats frying pan, in the process of heating, the raw material after the fragmentation constantly stir-fried in described frying pan; After frying pan is heated to 100 ~ 105 DEG C, the raw material after the fragmentation in described frying pan is inserted in squeezing machine squeeze immediately, collect liquid and namely obtain crude oil;
The refining of c, crude oil: insert in oil cauldron by described crude oil, then heat oil cauldron, during heating, constantly stirs the crude oil in described oil cauldron; After the crude oil in described oil cauldron is heated to 125 ~ 130 DEG C, immediately the crude oil in described oil cauldron is cooled to 80 ~ 90 DEG C, then add the deionized water that quality is the quality of crude oil 2 ~ 3% in described oil cauldron, then filter with high-precision filter I; After filtration completes, then add the mixture be made up of Ligusticum wallichii and peppermint that quality is described quality of crude oil 17 ~ 23%, after stirring, then filter with high-precision filter II, collect filtrate, get product.
Preferably, in order to protect the beneficiating ingredient in Semen Brassicae campestris not to be destroyed, in described step a, temperature when drying Semen Brassicae campestris is 50 ~ 80 DEG C.
Preferably, conveniently to the squeezing of stock oil vegetable seed, in described step b, described squeezing machine is expeller; Meanwhile, also in order to squeeze out the rapeseed oil in Semen Brassicae campestris as far as possible, temperature during squeezing is 85 DEG C.
Preferably, in order to the acid that can remove well in rapeseed oil is situated between (2-amino-5-naphthols-7 sulfonic acid), in described step c, in the described mixture be made up of Ligusticum wallichii and peppermint, the mass ratio of Ligusticum wallichii and peppermint is 1:1.
Preferably, in order to be filtered out by the phosphatide in rapeseed oil well, the filtering layer of described high-precision filter I has three layers; The order number of described three layer filtration layer is followed successively by 600 orders, 1000 orders and 2000 orders from top to bottom.
Preferably, in order to can the Ligusticum wallichii be added in rapeseed oil and peppermint be filtered out well, the filtering layer of described high-precision filter I has three layers; The order number of described three layer filtration layer is followed successively by 1000 orders, 2000 orders and 5000 orders from top to bottom.
Beneficial effect of the present invention is: rapeseed oil production technique provided by the present invention, is extract oil to Semen Brassicae campestris at a lower temperature, saves the beneficiating ingredient in rapeseed oil and the vegetable seed seedcake dregs of rice well, and make the rapeseed oil purity produced high, mouthfeel is good; Meanwhile, the utilization of rapeseed cake dregs is also beneficial to.In this production technique, first the process before squeezing has been carried out to Semen Brassicae campestris and has prepared, and first Semen Brassicae campestris is dried to water content be 1 ~ 2%, then in Semen Brassicae campestris the deionized water of even sprinkling oil vegetable seed quality 3 ~ 5%, and then heat in frying pan and stir-fry; After these operations, just can squeeze out the rapeseed oil in Semen Brassicae campestris well, improve the output of rapeseed oil, reduce the production cost of enterprise.
