What is oven preheating (what is the function of oven preheating?)

Common warm-up in life

Warm-up is a very common activity in life. People warm up,

On the one hand, it is for the safety of equipment during operation, such as:

1. Chemical preheating

Liquid chemical heating Preheating during the process: When heating with a test tube,

In order to heat evenly, first move left and right on the alcohol lamp, (if the test tube is fixed,

Then move the alcohol lamp left and right ) and then heated with an external flame to prevent the test tube from bursting.

There are also some warm-up behaviors that can improve the service life of the tool, such as:

2. Warm-up for automotive science

When the key is turned on, it is called warm-up. This warm-up refers to diesel vehicles.

Diesel has a high ignition point, so there will be a special glow plug to warm up before starting the car. When the ignition point of diesel is reached, the start will be smooth.

There is also a warm-up behavior that promotes the atmosphere of the event, which also becomes a warm-up of the atmosphere.

3. Warm up in marketing.

Or create an atmosphere for festivals or events, create momentum, etc.

However, these are not our knowledge points today. Today we will talk about preheating in baking.

Baking that failed during the preheating process

1. The finished product is not heated well, resulting in raw bottom burnt top.

2. Successful product surface dehydration, cracking, folding, etc.

3. The overall maturity of the finished product is not enough, the internal tissue is dry and hard, the bottom is wet and sticky, or it is difficult to remove the film.

4. The smell of the finished product is chaotic, and the taste is affected by the order.

Preheating for baking

Preheating in baking refers to heating the oven for a period of time before the green embryo enters the oven for formal baking.

Make it reach the predetermined temperature, and then put the green embryo into it for formal baking.

Why must preheat before baking?

The effect of preheating is equivalent to the effect of warming the cup when drinking coffee. Serving coffee in a warm cup will make the aroma and taste of the coffee better combined.

Oven preheating means that the oven needs to be heated to a certain temperature before baking, so that the temperature inside the oven is close to the temperature required for baking food.

On the one hand, the material will not affect the quality of the finished food due to the slow temperature rise,

to achieve a better taste, on the other hand, it saves time and reduces energy consumption.

For example, the unfinished state of some single products, such as the batter of cake products, needs to enter the high temperature state immediately from room temperature.

To ensure the rapid expansion of the internal tissue, the appearance is fluffy, and the internal tissue is soft.

In addition, the preheating of the oven can also play a role in sterilization and deodorization.

Because the oven is idleIt will breed bacteria or have an oily smell.

Preheating the oven can remove these odors before baking.

How to warm up?

For example, to bake biscuits, the recipe requires a temperature of 180 degrees. Before putting the biscuits in the oven,

turn on the power of the oven, adjust to 180 degrees, let the oven burn for 10 minutes, and put the biscuits in the oven to bake when the temperature in the oven reaches 180 degrees.

Preheating time: domestic household ovens generally do not have a preheating indicator light.

So pay attention to the condition of the heating pipe. When the heating tube turns from red to black, it means the preheating is complete.

Preheating times vary depending on temperature and oven size. Theoretically, the greater the energy, the smaller the oven

and the faster it will preheat. It usually takes 10 minutes to warm up.

The warm-up time should not be too long. Not only is energy wasted, but oven life is shortened if the oven is left empty for too long.

So, plan your preparation time in advance, and then start doing it step by step.

Preheat time is not included in the time required to bake food. For example, if you bake for half an hour, the total time required is 30 minutes plus preheat time.
