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 suction...

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 waste oil of fried food based on a continuous and uninterrupted method, and relates to the technical field of edible oil treatment. a turning body and a turning mechanism; a filter device is arranged at the oil inlet end of the first oil outlet pipe and the second oil outlet pipe in the casing; an oil suction cavity is arranged inside the turning body, and the two ends are respectively provided with a first oil suction port and a second oil suction port that communicate with each other. The oil suction port, the first oil suction port and the second oil suction port are all provided with a valve mechanism in a normally closed state; when the turning body moves, the first oil suction port is fitted with the filter device at the oil inlet end of the first oil outlet pipe, and The valve mechanism here is open, or the second oil suction port is fitted with the filter device at the oil inlet end of the second oil outlet pipe, and the valve mechanism here is open; the oil suction chamber is communicated with the external negative pressure pump pipeline. High-efficiency decontamination treatment of edible waste oil after fried food is used to facilitate the recycling and reuse of edible waste oil.

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. ...
