Embodiment 1

[0020] Appropriate amount of sesame seeds are removed through cleaning equipment to remove various impurities. After cleaning, the raw materials do not contain stones and iron substances, and the impurity content is less than 0.5%. Hot air drying, sesame temperature is 40 ℃ when drying. Water was removed from the sesame seeds to reduce the moisture content to 7% (W / W). Then enter the screw press machine to extract oil, the temperature of the sesame oil for feeding is 30°C, the screw speed is 20 rpm, and the oil outlet temperature is 45°C. The pressed oil is precipitated and finely filtered at 35°C to become pure natural edible sesame oil. The pressed cake can be further developed and utilized as food raw materials. The oil yield of this embodiment is 46.6%, the residual oil in the cake is 13.3%, and the production capacity is 5.55kg / h.

Embodiment 2

[0022] Appropriate amount of sesame seeds are removed through cleaning equipment to remove various impurities. After cleaning, the raw materials do not contain stones and iron substances, and the impurity content is less than 0.5%. Hot air drying, sesame temperature is 40 ℃ when drying. Water was removed from the sesame seeds to reduce the moisture content to 7% (W / W). Then enter the screw press machine for oil extraction, the temperature of the sesame oil fed into the feed is 35°C, the screw speed is 40 rpm, and the oil outlet temperature is 45°C. The pressed oil is precipitated and finely filtered at 30°C to become pure natural edible sesame oil. The pressed cake can be further developed and utilized as food raw materials. The oil yield of this embodiment is 43.0%, the residual oil in the cake is 16.1%, and the production capacity is 7.36kg / h.

Embodiment 3

[0024] Appropriate amount of sesame seeds are removed through cleaning equipment to remove various impurities. After cleaning, the raw materials do not contain stones and iron substances, and the impurity content is less than 0.5%. Hot air drying, sesame temperature is 40 ℃ when drying. Water was removed from the sesame seeds to reduce the moisture content to 8% (W / W). Then enter the screw press machine for oil extraction, the temperature of the sesame oil fed into the feed is 10°C, the screw speed is 20 revs / min, and the oil outlet temperature is 40°C. The pressed oil is precipitated and finely filtered at 10°C to obtain pure natural edible sesame oil. The pressed cake can be further developed and utilized as food raw materials. The oil yield of this embodiment is 40.5%, the residual oil in the cake is 21.1%, and the production capacity is 5.45kg / h.

Abstract

This invention provides a method for cold-pressing sesame oil at low temperatures. The cold-pressing method is simple, and the nutritious ingredients and active substances in sesame oil are largely retained. The pressed sesame oil is fragrant, clear and bright. The method comprises: (1) cleaning sesame, and air-drying by a dryer below 50 deg.C to a water content of 6-10 wt.%; (2) loading into an oil press at 5-35 deg.C, pressing, and discharging sesame oil below 50 deg.C; (3) precipitating, and fine-filtering at 20-40 deg.C to obtain natural and edible sesame oil. The method has such advantages as simple and rational process, and no environmental pollution. The proteins in the cold-pressed cakes are not denatured, and can be further developed and utilized.

Description

technical field [0001] The invention relates to a vegetable oil and a processing method thereof, in particular to a new technology of low-temperature cold pressing of sesame oil. Background technique [0002] Sesame, also known as flax, belongs to Sesamaceae and is an annual herb. It is an ancient oil crop and one of the four major edible oil crops in my country. The sesame oil that people eat at present is mostly the sesame oil with strong fragrance through roasting. The production method of the traditional water-substitution method of small grinding sesame oil is: cleaning, moistening seeds, frying seeds, raising smoke, grinding seeds, blending pulp, stirring oil and finally shaking and separating oil and other basic processes. Sesame oil produced by traditional techniques is darker in color and has a strong fragrance, which limits its range of use. Contents of the invention [0003] The invention provides a low-temperature cold-pressing method of sesame oil. The cold-...
