A toaster is a toaster. It is a machine that automatically mixes, ferments and bakes all kinds of bread after putting the ingredients in place according to the set procedures. It can be divided into household and commercial. The bread machine can not only make bread, but also make cakes, yogurt, rice wine and so on. The bread maker with manual mode function can also make fancy bread of various shapes, which is very suitable for professional bread makers. The powerful function of the bread machine not only allows users to easily make French, European, whole wheat and rice bread, but also can make rice cakes, rice cakes, fillings, shells, fried nuts, and even delicious foods such as yogurt and cheese through self-designed programs.
The bread machine is a machine that automatically mixes, ferments and bakes all kinds of bread after putting the ingredients in place according to the requirements of the machine. It can be divided into household and commercial. Bread making by bread machine mainly includes three processes: kneading, fermentation and baking. The principle of bread machine is to use the built-in computer program to solidify the three processes of making bread, and send out the instructions of kneading, fermenting or baking at a fixed time point, thus making bread. The typical process of bread making by bread machine is: kneading-fermentation-setting-fermentation-kneading-baking.
Composition structure
The bread maker is provided with an oven, kneading drums arranged in parallel and separately in the oven, and a drum driving part for rotating one of the kneading drums clockwise and counterclockwise. The connecting shaft extends eccentrically from the kneading drums and rotates around the rotating shaft of each corresponding kneading drum. The connecting rod is connected with the connecting shaft and transmits rotation between the kneading drums.
Principle of microwave heating
Generally speaking, heating media can be divided into nonpolar molecular dielectrics and polar molecular dielectrics. When there is no external electric field, polar molecules do not show polarity. If this medium is placed in an external electric field, each polar molecule will form an orderly arrangement along the direction of electric field force, and the opposite charges will be induced on the surface of the medium, which is called polarization. The stronger the applied electric field, the stronger the polarization. When the applied electric field changes direction, polar molecules also form an ordered arrangement in the opposite direction. If alternating electric and magnetic fields are applied, polar molecules will be magnetized repeatedly. The higher the frequency of alternating electric field, the faster the polarization of polar molecules rotates repeatedly. At this time, the kinetic energy of molecular thermal motion increases, that is, the heat increases, and the temperature of food also increases, thus completing the transformation from electromagnetic energy to heat energy.
The frequency of household microwave oven is 2450MHz, the direction of electric field changes 2.45 billion times per second, and the heat generated can be imagined. Microwave ovens use microwaves to cook food. It is an electronic vacuum tube-magnetron, which generates 2450MHz ultrashort wave electromagnetic waves, which are emitted to all parts of the oven through the microwave conductive element-waveguide. Through emission, conduction and absorption by food, polar molecules (such as water, fat, protein, sugar, etc. ) vibrates at an extremely high speed of 2.45 billion times per second, and the friction generated by vibration makes food.
