Embodiment 1

[0028] Dry the cleaned hemp seeds and enter the crusher, and the particle size of the crushed particles is 80 mesh. The hemp seed particles are transferred to a constant temperature drying oven, dried at 70° C., and the residual water content is measured. When the residual water content drops to 8%, cold pressing is carried out. A low-temperature double-screw cold press is used for cold pressing, the feed temperature is controlled at 50°C, the chamber temperature is 70°C, the pressure is 26MPa, and the pressing time is 240s to obtain crude oil. The crude oil was first cooled to room temperature, then further cooled to 5°C, and left to stand for 8 hours. Keep the low temperature and pass through a 20,000-mesh sieve to obtain a golden yellow clarified hemp seed oil.

Embodiment 2

[0030] Dry the cleaned hemp seeds and enter the crusher, and the particle size of the crushed particles is 100 mesh. The hemp seed granules are transferred to a constant temperature drying oven, dried at 90°C, and the residual water content is measured. When the residual water content drops to 10%, cold pressing is carried out. A low-temperature double-screw cold press is used for cold pressing, the feed temperature is controlled at 60°C, the chamber temperature is 80°C, the pressure is 30MPa, and the pressing time is 210s to obtain crude oil. The crude oil was first cooled to room temperature, then further cooled to 0°C, and left to stand for 6 hours. Keep the low temperature and pass through a 30,000-mesh sieve to obtain a golden yellow clarified hemp seed oil.

Embodiment 3

[0032] The cleaned hemp seeds are dried and put into a crusher, and the particle size of the crushed particles is 60 mesh. The hemp seed granules are transferred to a constant temperature drying oven, heated to 90° C. for drying by microwave, and the residual water content is measured. When the residual water content drops to 7%, cold pressing is carried out. A low-temperature double-screw cold press is used for cold pressing, the feed temperature is controlled at 60°C, the chamber temperature is 75°C, the pressure is 30MPa, and the pressing time is 300s to obtain crude oil. The crude oil was first cooled to room temperature, then further cooled to 5°C, and left to stand for 10 hours. Keep the low temperature and pass through a 30,000-mesh sieve to obtain a golden yellow clarified hemp seed oil.

Abstract

The invention provides a physical squeezing preparation technology for hempseed oil. The technology comprises the following steps that hempseeds are broken, drying is performed at constant temperature, cold squeezing is performed through a dual-spiral low-temperature cold squeezer, cooling is performed, and oil residues separated out. According to the production technology, the steps are simple, the oil extraction rate is high, nutrient components of the hempseed oil are well stored, and the color of the oil is good.

Description

technical field [0001] The invention belongs to the field of edible oil processing, in particular to a process for preparing hemp seed oil by physical pressing. Background technique [0002] Cannabis, also known as hemp and hemp, is one of the main original crops in my country and has a long history of cultivation. Hemp seed oil, made from hemp seeds, contains a balanced ratio of omega-3, 6 and 9 fatty acids in a ratio of 1:2:1, which makes it the most ideal nutritional supplement, golden ratio oil, considered the most perfect natural food. In addition, hemp also contains nutrients for skin care, which has a special effect on dry skin. [0003] Hemp seed oil is particularly rich in essential fatty acids, which are its characteristics. Essential fatty acids are known to prevent many diseases such as heart disease, high blood pressure, high cholesterol, cancer, and arthritis. Because they cannot be produced by the human body, they must be ingested through food ;Essential fa...
