Problems solved by technology

[0003] The quality of wild iron walnut oil is better than ordinary walnut oil, but there are many problems in the existing iron walnut oil preparation process, especially for the century-old wild iron walnut, there is no suitable walnut oil processing technology
Existing iron walnuts also have the prior art of directly pressing without separating the shell and kernel, but there are many problems. The hard walnut shell not only forms a huge pressure on the walnut crushing equipment, but also the excessive walnut shell is crushed and mixed with Mixing in the walnut kernels to be oiled not only increases the workload of pressing, but also makes the oil residue contain more oil that is difficult to squeeze out. In the prior art, in order to increase the oil yield of iron walnuts, crushed walnuts are used The method of directly adding walnut kernels in the granules, this method does not solve any problems in essence, and makes pure wild iron walnut oil mixed with other varieties of walnut oil, reducing the quality of wild iron walnut oil

Embodiment 1

[0028] A kind of iron walnut oil extraction process that effectively improves oil yield, comprises the following steps:

[0029] 1) Pretreatment: First, divide the iron walnuts to be squeezed into five equal parts, and cut 0.5 of them twice to separate the iron walnut kernels; Part of the walnut shells around the iron walnuts are cut and discarded to ensure that the weight ratio of the remaining walnut shells to walnut kernels is 1~1.5:10, and then the cut iron walnuts are dried at 30°C until the water content is low 8%, then crush the dried iron walnut once, screen, remove the coarse shell, and crush again to the particle size of iron walnut powder below 0.5mm; then mix the iron walnut powder and iron walnut kernel evenly to obtain oil to be pressed Raw materials; the described iron walnut is a hundred-year-old tree wild iron walnut without mildew; the two cuts are to cut the walnut along two symmetrical positions 0.5cm away from the central axis of the iron walnut; the descr...

Embodiment 2

[0034] A kind of iron walnut oil extraction process that effectively improves oil yield, comprises the following steps:

[0035] 1) Pretreatment: First, the iron walnuts to be pressed are divided into five equal parts, and two of them are cut with two knives to separate the iron walnut kernels; Part of the walnut shell around the iron walnut is cut and discarded to ensure the weight ratio of the remaining walnut shell to walnut kernel is 1.5:10, and then the cut iron walnut is dried at a temperature of 55°C until the water content is lower than 8%. , then crush the dried iron walnut once, screen, remove the coarse shell, and crush the iron walnut powder to a particle size below 0.2 mm; then mix the iron walnut powder and iron walnut kernel evenly to obtain the raw material for oil extraction; The two cuts described are to cut walnuts along two symmetrical positions of 2 cm from the iron walnut mid-axis plane; walnuts and four pieces of discarded walnut shells; the thickness o...

Embodiment 3

[0040] A kind of iron walnut oil extraction process that effectively improves oil yield, comprises the following steps:

[0041] 1) Pretreatment: First, divide the iron walnuts to be squeezed into five equal parts, and cut one of them twice to separate the iron walnut kernels; Part of the walnut shell around the iron walnut is cut and discarded to ensure that the weight ratio of the remaining walnut shell to walnut kernel is 1.2:10, and then the cut iron walnut is dried at 40°C until the water content is lower than 8 %, then the iron walnut after drying is crushed once, screened, the coarse shell is removed, and the particle size of the iron walnut powder is crushed again below 0.05mm; then the iron walnut powder and the iron walnut kernel are mixed evenly to obtain the oil raw material to be squeezed; The iron walnut described is a hundred-year-old wild iron walnut without mildew; the two cuts are to cut the walnut at two symmetrical positions 1 cm away from the central axis ...

Abstract

The invention discloses a juglans sigillata oil squeezing process capable of effectively improving the oil yield. The process comprises the following steps: 1) pre-treatment, namely firstly, dividing juglans sigillata to be oil-squeezed into five parts equally, and sectioning 0.5-2 parts thereof by two cuts to separate out juglans sigillata kernels; cutting the residual juglans sigillata to be oil-squeezed in a square shape, wherein the weight ratio of the residual walnut shells and the walnut kernels is (1-1.5) to 10, drying the mixture, then primarily crushing and screening the mixture, removing coarse shells, and crushing the mixture again to obtain juglans sigillata powder; uniformly mixing the juglans sigillata powder with the juglans sigillata kernels to obtain a raw material to be oil-squeezed; 2) low-temperature cold squeezing, namely performing low-temperature cold squeezing for 2-4 times on the raw material to be oil-squeezed pretreated in the step (1) to obtain crude oil; and 3) post treatment, namely precipitating, filtering and purifying the obtained crude oil to obtain the juglans sigillata oil. The oil squeezing process disclosed by the invention is capable of reserving nutritional components in walnut oil, and is stable in quality and high in oil yield, and the obtained juglans sigillata oil is clear in color and rich in nutrition.

Description

technical field [0001] The invention belongs to the technical field of edible oil production, and in particular relates to an iron walnut oil extraction process which can effectively improve the oil yield. Background technique [0002] The walnut tree is a deciduous tree. The drupe-like nut is spherical, the exocarp is smooth, the mesocarp is fleshy, and the endocarp is hard and wrinkled. The nuts are edible, oil-pressed, and used as medicine. The nutritional value of walnuts is very high. It has the effects of nourishing the brain, strengthening the spleen, nourishing the blood, nourishing the lungs, nourishing the mind, and prolonging life. It can be widely used in the treatment of neurasthenia, hypertension, coronary heart disease, emphysema, and stomach pain. According to the "Compendium of Materia Medica", walnut oil has the functions of "reinforcing brain and intelligence, benefiting essence and black hair, nourishing qi and nourishing blood, strengthening muscles and ...
