Frying equipment for frying food, frying machine price believes that the fried food is placed for a long time, the fried food has a rich aroma, the color is golden, and the processing of the food by frying is simple, so Fried foods have always been a type of food that the public likes in China. The fryer is the equipment used to fry the food. What are the methods of frying the food to fry the food?

And put the sugar on the surface, blow it dry, put it into the hot oil pan, keep turning it, and put the hot oil into the abdomen. When the whole body is fried to pale yellow, then the oil pan will be high and the raw materials will be The oil is immersed in the oil and then poured out. When the oil temperature rises, it is taken out.
2, dry fried. The frying equipment will mix the raw materials with the seasoning, remove the water, mix the dry powder, and fry the coke. The raw material can be crispy and the color is browned.
3, soft fried. After hanging the paste with a small piece of a small piece, a thin piece, a long square strip or the like, the oil is burned in a pot when the oil is boiled in the pot, and the fried pot is fried until the appearance is hard.
4, clearing. The raw materials are mixed with soy sauce, salt and wine, and the frying machine is fried with fire. Generally do not hang paste, fried into a thin and tender inside.
5, fried. The ingredients are cooked and cooked, and the egg white and powder paste are hung on the outside, and then fried in a pan and fried until the outer layer is deep yellow. The characteristic of crispy frying is that it is rotten and crunchy.

Detection principle
1. pH: The pH value in the range of 5-9 is measured by the pH indicator, and the pH value of the fresh urine of a normal person is between 5-7.
2. Nitrite: The reaction is based on the reduction of nitrate to nitrite by Gram-positive bacteria in the urine. The nitrite reacts with p-aminobenzenesulfonic acid to form diazonium compounds, which are then combined with N-(1-naphthalene) )-3 aminopropanesulfonate combined with a pink color.
3. Glucose: According to the reaction principle of glucose oxidase, glucose oxidase specifically oxidizes glucose to generate glucuronic acid and hydrogen peroxide. Under the action of hydrogen peroxide, hydrogen peroxide oxidizes the indicator and turns color. .
Classification
Urinalysis test strips are divided into visual series and machine series. The visual inspection series is divided into several models according to different inspection items; the machine inspection series is divided into several models according to different applicable instruments.
1. Classification by measurement method
1) Visual inspection series
When observing the result, compare the color with the standard color code within the time specified on the color code, judge and read the result.
2) Machine test series.
For instrument operation, refer to the instruction manual of the Urine Analyzer used.
2. According to the number of measurement items
There are single-item, 2-item, 4-item and multiple test strips. Currently, 10-item or 11-item multiple test strips are most commonly used in hospitals.
3. Classification by structure
Urinalysis test strips with single-layer membrane structure and multi-layer membrane structure.
