Problems solved by technology

The acid value and peroxide value of fats and oils continue to rise, and the quality of fried food cannot be guaranteed
Therefore, it is necessary to recycle and purify the waste cooking oil in time. However, the existing conventional alkali refining method cannot meet the requirements of high standards, such as trace metals, trace soap particles, phospholipids and other colloidal substances in the oil cannot be effectively recovered. removal, therefore, the problem needs to be solved

[0032] The inside of the turning body 5 is provided with an oil suction cavity 51, and the two ends are respectively provided with a first oil suction port 52 and a second oil suction port 53 connected to each other. The first oil suctio...

Embodiment 2

[0044] A process for purifying fried food waste oil based on continuous and uninterrupted mode, comprising the following steps:

[0045] S1. Preheating and acid treatment: Preheat the waste cooking oil after filtering out solid impurities to 70°C, pump it into a reaction tank for heat preservation, and add food-grade phosphoric acid accounting for 0.05% of the oil while stirring , and its concentration is 85%, to obtain acid-treated mixed oil;

[0046] S2. Rapid cooling and coagulation impurity treatment: quickly lower the acid-treated mixed oil after S1 treatment to 30°C, and then add food-grade lye with a concentration of 20% to it according to the acid value to be lowered, and the reaction time is 8 minutes. Coagulate the impurities to form a group of flocculent impurities, and obtain the alkali-treated mixed oil;

[0047] S3. Continuous and uninterrupted purification treatment: pump the alkali-treated mixed oil liquid after S2 treatment into the oil inlet pipe, and then c...

Embodiment 3

[0049] A process for purifying fried food waste oil based on continuous and uninterrupted mode, comprising the following steps:

Abstract

The invention provides a device and process for purifying fried food waste oil based on a continuous mode, and relates to the technical field of edible oil treatment. The device comprises a shell, anoil inlet pipe, a first oil outlet pipe, a second oil outlet pipe, an overturning body located in the shell, and an overturning mechanism; filters are arranged at the oil inlet ends, located in the shell, of the first oil outlet pipe and the second oil outlet pipe; an oil suction cavity is formed in the overturning body, a first oil suction port and a second oil suction port which are communicatedwith each other are formed in the two ends of the overturning body respectively, and valve mechanisms in a normally-closed state are arranged at the first oil suction port and the second oil suctionport respectively; when the overturning body acts, the first oil suction port is attached to the filter at the oil inlet end of the first oil outlet pipe, the valve mechanism at the position is opened, or the second oil suction port is attached to the filter at the oil inlet end of the second oil outlet pipe, and the valve mechanism at the position is opened; and the oil suction cavity is communicated with an external negative pressure pump pipeline. Edible waste oil obtained after deep frying of food is used is subjected to efficient impurity removal treatment, so recycling of the edible waste oil is facilitated.

Description

technical field [0001] The invention relates to the technical field of edible oil treatment, in particular to a device and process for purifying fried food waste oil in a continuous and uninterrupted manner. Background technique [0002] In the field of fried food processing, such as meat products, soybean products, etc., during the frying process, the cooking oil used for fried food is heated at high temperature for several hours in the environment where water, air and food residues coexist, and the oil is generated. Many chemical reactions, such as: organic pigments produced by oxidation, hydrolysis, thermal decomposition and polymerization. With the prolongation of frying time, the quality of oils and fats decreased significantly in terms of sensory, nutrition and efficacy. The acid value and peroxide value of oil continue to rise, and finally the quality of fried food cannot be guaranteed. Therefore, it is necessary to recycle and purify the waste cooking oil in time. ...
