Problems solved by technology

[0002] Due to the influence of its geographical environment in Northwest China, the sunflower seeds planted locally have sufficient sunshine and a long growth cycle, and are rich in linoleic acid, vitamins and other substances beneficial to the human body; but at the same time, their wax content is relatively high. Affect the clarity and taste of refined oil
In the current production process, the traditional dewaxing method cannot effectively remove the wax in this kind of sunflower seeds, and it may also cause the loss of nutrients in the oil due to the high operating temperature, which affects the flavor and quality of the sunflower oil. bad influence

Embodiment 1

[0019] A kind of processing technology of extruding sunflower seed oil, its process comprises the steps:

[0020] (1) Screening sunflower seeds, the oil content of which is 30% to 50%, utilizes a cleaning sieve and a demagnetizer to remove impurities such as iron, stone, grass, and soil therein;

[0021] (2) Put the sunflower seeds into the drum frying pan to heat them evenly, and then roast them at 160°C, for 50 minutes, and at the rotational speed of the drum at 20-25 rpm. The fried sunflower seeds are cooled by a fan, and the temperature of the sunflower seeds is reduced to 45°C within 15 to 20 minutes, and then placed in a cool place and spread into a layer of sunflower seeds with a thickness of no more than 5cm, while preventing dust and debris, etc. Pollution, after natural cooling to room temperature, raw materials are obtained;

[0022] (3) After weighing raw materials and utilizing steel mills to pulverize them, they are packed in clean containers to obtain pasty slu...

Abstract

The invention belongs to the field of processing of edible oil, and relates to a pressing processing technology of sunflower seed oil. The processing technology comprises the following steps of sorting, and removing impurities; baking and frying for 50min at the temperature of 160 DEG C; cooling by a fan, naturally cooling to room temperature, crushing the obtained raw material into oil paste, adding water of which the mass is equal to 8 to 10% of the mass of the raw material, and uniformly stirring; pressing by a hydraulic oil press at the pressure equal to or less than 80MPa, obtaining crude oil, and filtering; degumming by edible salt solution; dewaxing by food-level perlite at the system temperature equal to or lower than 0DEG C, so as to obtain the sunflower seed oil. The sunflower seed oil obtained by the processing technology has the advantages that the oil yield rate is higher, and is 38 to 40%; the content of wax is lower, and is 12 to 18mg / kg; the flavor is good, the quality is high, and the heavy oil fragrance is obtained.

Description

technical field [0001] The invention belongs to the field of edible oil processing, and relates to a production process of sunflower oil, in particular to a pressing process of sunflower oil. Background technique [0002] Due to the influence of its geographical environment in Northwest China, the sunflower seeds planted locally have sufficient sunshine and a long growth cycle, and are rich in linoleic acid, vitamins and other substances beneficial to the human body; but at the same time, their wax content is relatively high. Affect the transparency and taste of refined oil. In the current production process, the traditional dewaxing method cannot effectively remove the wax in this kind of sunflower seeds, and it may also cause the loss of nutrients in the oil due to the high operating temperature, which affects the flavor and quality of sunflower oil. adverse effects. Therefore, need to develop the processing method of a kind of high nutritive value, the low fragrance sun...
