Embodiment 1

[0024] A preparation method of sesame oil, comprising the steps of:

[0025] S1: drying the picked fresh hemp seed fruit in the sun until the hemp seed peel is cracked, then removing the peel, and drying at a temperature of 85-90°C until the water content is 3%;

[0026] S2: Shelling the dried hemp seeds in step S1, so that the shell content in the hemp seeds kernel is ≤0.5%;

[0027] S3: Dry the tea seed kernels in step S2 at an air pressure of -0.1 to -0.095MPa and a temperature of 85°C until the moisture content is 0.5%, and then cool the tea seed kernels to room temperature;

[0028] S4: cold pressing the tea seed kernels cooled to room temperature in step S3 to obtain pressed oil containing residue;

[0029] S5: After heating the squeezed oil containing slag in step S4 to 85°C and filtering to remove impurities, the impurity content in the oil is <0.05%;

[0030] S6: To the squeezed oil in step S5, add activated clay, activated carbon, and silica gel that account for o...

Embodiment 2

[0033] S1: drying the picked fresh hemp seed fruit in the sun until the hemp seed peel is cracked, then removing the peel, and drying at a temperature of 85-90°C until the water content is 9%;

[0034] S2: Shelling the dried hemp seeds in step S1, so that the shell content in the hemp seeds kernel is ≤0.5%;

[0035] S3: Dry the tea seed kernels in step S2 at an air pressure of -0.1 to -0.095MPa and a temperature of 90°C until the water content is 1.5%, and then cool the tea seed kernels to room temperature;

[0036] S4: cold pressing the tea seed kernels cooled to room temperature in step S3 to obtain pressed oil containing residue;

[0037] S5: After heating the squeezed oil containing slag in step S4 to 90°C and filtering to remove impurities, the impurity content in the oil is <0.05%;

[0038] S6: To the squeezed oil in step S5, add activated clay, activated carbon, and silica gel that account for 0.5%: 0.4%: 0.1% of the oil weight, and then the air pressure is -0.1~-0.09...

Embodiment 3

[0041] S1: drying the picked fresh hemp seed fruit in the sun until the hemp seed peel is cracked, then removing the peel, and drying at a temperature of 87°C until the moisture content is 6%;

[0042] S2: Shelling the dried hemp seeds in step S1, so that the shell content in the hemp seeds kernel is ≤0.5%;

[0043] S3: Dry the tea seed kernels in step S2 at an air pressure of -0.1 to -0.095MPa and a temperature of 87°C until the water content is 1.0%, and then cool the tea seed kernels to room temperature;

[0044] S4: cold pressing the tea seed kernels cooled to room temperature in step S3 to obtain pressed oil containing residue;

[0045] S5: After heating the squeezed oil containing slag in step S4 to 87°C and filtering to remove impurities, the impurity content in the oil is <0.05%;

[0046] S6: To the squeezed oil in step S5, add activated clay, activated carbon, and silica gel that account for oil weight ratio of 0.45%: 0.35%: 0.2%, and then the air pressure is -0.1~-...

Abstract

The invention discloses a preparation method for cannabis oil and belongs to the technical field of plant oil processing. According to the method, the pure cannabis oil is obtained after impurities are filtered out in a purely-physical cold pressing mode. No chemical reagent is added during oil and fat refining, effective active ingredients of the cannabis oil are effectively reserved through a relative low-temperature purely-physical method, and the added value is increased. No deacidification or decoloration or deodorization or else is conducted during oil and fat refining, the cannabis oil meeting the national GB11765-2003 pressed tea seed oil standard can be obtained, and the natural flavor of the cannabis oil is reserved. The process is simple, production efficiency is high, the period is short, the color of the oil is light, the oil yield and purity are high, production cost is low, and application and popularization are easy.

Description

【Technical field】 [0001] The invention belongs to the technical field of vegetable oil processing, and in particular relates to a preparation method of hemp oil. 【Background technique】 [0002] Hemp oil has the reputation of "longevity oil". Hemp oil contains a large amount of anti-aging vitamin E, selenium, zinc, manganese, germanium and other elements. [0003] Most of the existing hemp oil preparation methods use drying, crushing, flaking, and high-temperature steaming and frying above 110°C, and then oil is extracted by high-temperature hot pressing. The processing procedures are more complicated, the equipment investment is large, and the production cost is high. The oil color is darker and the quality is poor. It must go through deacidification, dehydration, decolorization, deodorization, degreasing and other refining processes before it can become first-class pressed oil. However, how to solve the problems of high production cost, poor quality, low oil yield and los...
