ZEL series medium-sized frying pipeline adopts oil-water mixed filter residue structure and full oil longitudinal scraping or side scraping system, variable frequency speed regulation. When frying, the residue of the explosive product sinks into the water under the tank, and the residue will not form carbon, and can be released through the sewage valve with the water. At the same time, a large amount of edible oil contained in the residue returns to the reservoir after oil-water separation. In this way, not only greatly prolonged the use cycle of oil, reduced oil consumption, oil-saving effect is very obvious, but also make fried products better color, fragrance, taste, appearance is more clean and beautiful. Setting up lifting system of the machine can raise the conveyor to a proper height, which makes the cleaning and maintenance of the machine very convenient. Suitable for users whose frying time is between 15 seconds and 8 minutes. After technical processing, the machine can adapt to various energy sources to meet the different requirements of users. This machine is especially suitable for large, medium and small enterprises.
