Abstract
Description
Frying device Technical Field
[0001] The utility model relates to the technical field of cooking equipment, in particular to a frying device. Background Art
[0002] Deep fryers are commonly used to fry large quantities of battered food, such as chicken, fish, or French fries. During the frying process, food crumbs, batter, and the like fall from the fried food. If these crumbs, batter, and the like remain in the frying oil, they can affect the taste of the fried food.
[0003] Existing deep fryers usually use new cooking oil to replace part of the frying oil or regularly filter the frying oil. The one-time filtration of the frying oil means that the frying oil in the deep fryer is filtered through a filter structure to filter out the oil residue and harmful substances therein, and then discharged into an oil storage tank. Finally, the frying oil in the oil storage tank is transported to the deep fryer for use through an oil pump.
[0004] The filtering method of this type of fryer has the following problems:
[0005] 1. It is usually necessary to filter the frying oil in the pot after frying. The food crumbs or small particles of batter dropped during the frying process are easily burnt under high temperature frying, affecting the overall frying quality.
[0006] 2. The method of filtering the frying oil once at a fixed time cannot control the quality index of the frying oil. It is difficult to avoid that the frying oil is not filtered in time after being used for a long time, resulting in fried foods absorbing harmful substances in the frying oil, which is not good for human health and has low reliability of the fryer.
