Separation and purification device for edible oil pre-processing

Abstract

The invention discloses a separation and purification device for edible oil pre-processing. The device includes an oil intake funnel coarse filtration sieve, a fine filtration sieve and an evaporation tank. The bottom of the oil intake funnel is fixedly connected to a sieving pipe, a coarse impurity discharge port is fixedly arranged on one side of the sieving pipe inner wall, the outside of the coarse impurity discharge out is in threaded connection with a coarse impurity cover, the coarse filtration sieve is fixedly connected to the bottom of the coarse impurity discharge port and the sieving pipe inner wall, a fine impurity discharge port is fixedly arranged on the sieving pipe inner wall at the bottom of the coarse filtration sieve, and the outside of the fine impurity discharge out is in threaded connection with a fine impurity cover. According to the invention, fixed plates are fixedly connected to the evaporation tank, and low temperature electric heating tubes are fixedly mounted on the fixed plates for heating and baking of product oil, as the boiling point of edible oil is far higher than water, water in edible oil can be evaporated by means of appropriate temperature, and edible oil is not affected, so that the evaporated edible oil can be stored for a longer time.

Description

technical field [0001] The invention relates to the technical field of edible oil processing, in particular to a separation and purification device for preprocessing edible oil. Background technique [0002] Edible oil, also known as "edible oil", refers to animal or vegetable fats used in the process of making food. It is liquid at room temperature. Due to the source of raw materials, processing technology and quality, common edible oils are mostly vegetable oils, including corn oil, peanut oil, hemp oil, corn oil, olive oil, camellia oil, palm oil, canola oil, sunflower oil, soybean oil , sesame oil, linseed oil (flax oil), grape seed oil, walnut oil, peony seed oil and so on. [0003] 1. There will be a lot of impurities in the crude oil produced for the first time in the production process of edible oil. If the impurities are not separated from it, the quality of edible oil will be seriously affected, and the taste of edible oil will be reduced. [0004] 2. Due to the...

Problems solved by technology

[0003] 1. There will be a lot of impurities in the crude oil produced for the first time in the production process of edible oil. If the impurities are not separated from it, the quality of edible oil will be seriously affected, and the taste of edible oil will be reduced.

[0004] 2. Due to the different dry humidity of the raw materials used in the pressing process of edible oil, the moisture content in some finished oils after pressing is too high, which is very unfavorable for the long-term preservation of edible oil
