preparation example Construction

[0037] Step A, the preparation of Jatropha jatropha crude oil;

[0038]Step B, carry out the degumming process to the Jatropha jatropha crude oil obtained in the step A, the process is as follows:

[0039] Heat the Jatropha crude oil. When the oil temperature rises to 40°C, start heating water and stir for 35-45 minutes. The temperature of the hot water is 5-15°C higher than the oil temperature. The content of the hot water is the phospholipid content of the Jatropha crude oil 4.5 ~5.5 times; then raise the oil temperature to 55°C, add an oxalic acid solution with an oil weight of 3%~8% and a concentration of 25%~35%, and stir for 30~40min to obtain degummed oil. The stirring speed of the above stirring is 60~70rpm;

[0040] Step C, deacidifying the degummed jatropha oil obtained in step B, the process is as follows: heating the degummed jatropha oil obtained in step B to 85-90°C, adding 0.05-0.06% of the oil weight to a concentration of 70 % phosphoric acid, after homogeneou...

Embodiment 1

[0046] Select Jatropha jatropha fruits, remove the deteriorated Jatropha jatropha fruits and foreign matter, so that the impurity content is ≤2%; soak the selected Jatropha jatropha fruits in 0.6% dilute lye at 50°C for not less than 30 minutes, and then immerse them in cold water Rinse the jatropha fruit; then dry the peeled jatropha fruit and press it in an extruder at room temperature. The walnut kernels are divided into 15KG bags and put into the mold of the extruder. Separation of slices; pressing adopts segmental boosting method, the pressure of the pre-pressing section with a pressure of 10MPa is boosted at a speed of 4MPa / min, and the pressure is raised to 40MPa to release the pressure and discharge; the squeezed jatropha oil is filtered to remove slag or The crude oil a and the oil residue are obtained by centrifuging and removing the residue, and the crude oil b is recovered by pressing the oil residue, and the crude oil b is mixed with the crude oil a to obtain the j...

Embodiment 2

[0048] Select Jatropha jatropha fruits, remove the deteriorated Jatropha jatropha fruits and foreign matter, so that the impurity content is ≤2%; soak the selected Jatropha jatropha fruits in 0.5% dilute lye at 60°C for not less than 30 minutes, and then immerse them in cold water Rinse the jatropha fruit; then dry the peeled jatropha fruit and press it in an extruder at room temperature. The walnut kernels are divided into 18KG bags and put into the mold of the extruder. Separation of slices; pressing adopts segmented boosting method, the pressure of the oil outlet section with a pressure of 15MPa is boosted at a speed of 2MPa / min, and the pressure is released after the pressure rises to 40MPa; the squeezed jatropha oil is filtered to remove residue or The crude oil a and the oil residue are obtained by centrifuging and removing the residue, and the crude oil b is recovered by pressing the oil residue, and the crude oil b is mixed with the crude oil a to obtain the jatropha cr...

Abstract

The invention discloses a refining method of Idesia polycarpa edible oil, relating to the technical field of refining of Idesia polycarpa oil. The refining method comprises the steps of: 1) preparation of Idesia polycarparaw oil; 2) degumming treatment; 3) depickling treatment; 4) decoloring treatment; 5) debitterizing treatment; 6) deodorizing treatment; and 7) filtration to obtain the finished Idesia polycarpa oil. The refining method of the Idesia polycarpa edible oil has the advantages of safety, environment protection, high oil yield and impurity free, and improves the quality of the Idesia polycarpa oil.

Description

technical field [0001] The invention relates to the technical field of jatropha oil refining, in particular to a refining method of jatropha edible oil. Background technique [0002] Jatropha magnolia is a positive fast-growing tree species, which has no strict requirements on climatic conditions and has strong growth adaptability: drought tolerance, barren tolerance, high temperature and low cold resistance (-14°C ~ 40°C), warm climate and fertile soil, suitable soil PH The value is 6.15 to 7.15. It can grow normally in weakly acidic, neutral and weakly alkaline sandy soils. It grows faster in places with sunny terrain, loose soil and good drainage. The annual rainfall is 800 mm to 2000 mm. , usually distributed at an altitude of 900-2000 meters, it is difficult to see below an altitude of 900 meters. Produced in the southern part of the three provinces of Shaanxi, Gansu and Henan, the second central and southern provinces, the six eastern China provinces, the second south...
