Problems solved by technology

Obviously, although the above method can remove the existing oxidative deterioration components in the oil, it will also be exposed to more oxygen during the treatment process, resulting in a new oxidation process, which greatly shortens the shelf life of the product. Generally, it is stored for 15 months. Grease will have different degrees of odor

Embodiment Construction

[0021] The first embodiment: as figure 1 The shown tank body 1 represents the container used for oil refining, which can be deacidification tank, degumming tank, decolorization tank, deodorization pot, finished oil tank and filling equipment used for vegetable oil refining, and can be used crude oil tank for edible vegetable oil processing, Hydration tank, alkali refining tank, dewaxing tank, finished oil tank and filling equipment, the tank body 1 is provided with an oil inlet 3 and an oil outlet 5. Of course, the tank body 1 is also provided with other devices such as brackets, which are omitted because they are irrelevant to the description. It is characterized in that two pipes are arranged above the tank body 1, one is an exhaust pipe 2, and the other is a nitrogen filling pipe 4. Exhaust pipe 2 can be a natural exhaust pipe or a one-way pipe that does not advance, and its effect is to get rid of the oxygen in the container. There are many ways to discharge oxygen, and ...

Abstract

The invention relates to a method and equipment for processing oil, namely a process and equipment for preserving and refining plant oil. The process is characterized in that plant oil is isolated from oxygen in the process of refining. The equipment comprises a tank body (1) for refining various oils, the tank body (1) is provided with an oil inlet (3) and an oil outlet (5), as well as an exhaust pipe (2) and a nitrogen filling pipe (4). The process has the beneficial effects that oxygen is isolated as less as possible during processing, and oil is refined and packaged in oxygen-free environment, so that the peroxidation value of the product is far lower than a standard value, the shelf life of the product is greatly prolonged. The process has the characteristics of simple equipment, low cost and the like, is easy to implement, and has a good application prospect.

Description

technical field [0001] The invention relates to an oil processing method and equipment, namely a vegetable oil quality-preserving refining process and equipment. Background technique [0002] The peroxide value is one of the important indicators of the quality of vegetable oil products. If the peroxide value exceeds the standard, it means that the product is prone to or has undergone qualitative change. Therefore, in the production of vegetable oil, especially in the production of edible vegetable oil, it is hoped to reduce the peroxide value. The current national standard requires that the peroxide value should be ≤0.25g / 100g, equivalent to 19.7meq / Kg. However, since the oil is in the air environment during processing, it is difficult to avoid oxygen, active oxygen will enter the oil, and oxidation will inevitably occur. Therefore, it is not easy to reduce the peroxide value. At present, the method of refining and deodorization is mainly used to reduce the peroxide value...
