The working principle of oil-water separator is as follows:

1. Principle of unpowered kitchen oil-water separator: This kitchen oil-water separator is a small basket made of perforated plates, which is usually called a slag-separating basket. The slag-separating basket is placed in the kitchen oil-water separator near the water inlet. After the catering sewage enters the equipment, the leftovers and other residues can be separated first.

however, it is necessary to clean the slag basket regularly. The restaurant sewage enters the equipment after passing through the slag basket. With the help of the gravity principle of the equipment, the restaurant sewage stays in the equipment for a certain period of time, so that the oil and water leave, and the oil floats on the water surface to form an oil layer.

2. Principle of the driving force kitchen oil-water separator: The driving force kitchen oil-water separator collects and discharges residues through a slag scraper or a spiral slag removal system, and then generates small bubbles through an air pump, and the releaser releases these small bubbles at the bottom of the water.

because the volume of air bubbles is similar to that of oil, they are easy to stick together, so small air bubbles will float to the top quickly in water, and oil will be brought to the upper layer at the same time, realizing the separation of oil and water.

The classification of kitchen oil-water separator is as follows:

Kitchen oil-water separator can be divided into two types: driving and unpowered:

1. Unpowered kitchen oil-water separator: unpowered kitchen oil-water separator does not need to be electrified, and it can achieve good oil removal effect through the principle of gravity and the role of inclined pipes. Moreover, the equipment has an oil sump, and the oil can automatically flow out of the equipment, as long as an oil drum is placed at the oil outlet of the equipment.

2. driving force kitchen oil-water separator: kitchen oil-water separator with driving force needs to be electrified, and it can be divided into automatic oil-water separator, semi-automatic oil-water separator and full-automatic oil-water separator according to different configurations.

The functions of oil scraping, air flotation and heating can be increased by electricity, so that the effect of oil-water separation can be effectively improved. The fully automatic equipment can automatically scrape slag, thus realizing the automatic discharge of waste residue, and only a slag collecting barrel needs to be placed at the slag outlet of the equipment.
