Problems solved by technology

[0003] At present, the commonly used oil extraction process is mainly the hot pressing process. The oil is steamed and fried at a high temperature of about 140°C for a long time (more than 1 hour) and then pressed, which leads to the dark color and poor quality of the pressed crude oil, which requires complicated The "five degumming" (degumming, deacidification, decolorization, dewaxing and deodorization) refining process can meet the edible requirements, and the micronutrients VE, sterols and polyphenols in the oil are seriously damaged
The Luzhou-flavored small oil mill that is becoming more and more popular now uses the high-temperature frying seed pressing process to make oil, and the refining only uses the hydration degumming process to "wash the oil". Although the finished oil retains the aroma flavor, it also retains However, the color of the oil is darker, and the water content in the oil is easy to exceed the standard, so the shelf life is short. Generally, it can only be squeezed and sold on the spot, and there are more food safety risks.

Abstract

The invention relates to an automatic freshly-squeezed and freshly-sold method for high-quality edible oil. The method comprises the following steps: 1), preparing a standard material, 2), supplying the standard material to each squeezing and selling site and 3), automatically squeezing, filtering, temporarily storing and quantitatively filling and selling finished oil on a squeezing and selling site as required. According to the method, automatic continuous or intermittent oil pressing, oil refining, temporary storage, self-service filling and selling of edible oil can be achieved on the selling site, and the edible oil is safe in quality, rich in nutrition, bright in color and luster and rich in fragrance.

Description

technical field [0001] The invention relates to the technical field of oil processing, and more specifically relates to a method for automatically squeezing and selling high-quality edible oil. Background technique [0002] my country is a big consumer of edible oil. In 2017, the per capita daily consumption of oil was as high as 74 grams, and it showed an increasing trend year by year. Edible oil is an important source of fat and energy that people need, and it is also the main source of essential fatty acids linoleic acid and linolenic acid, which can promote the absorption and utilization of fat-soluble vitamins and play an important role in human health, but excessive intake will increase the risk of disease The risk of chronic diseases such as obesity, diabetes, cardiovascular disease, and fatty liver. Therefore, the "Dietary Guidelines for Chinese Residents (2016 Edition)" proposes that the daily intake of edible oil for Chinese residents should not exceed 25 grams or...
