Toaster Solution
Toaster (toaster), English name Toaster, is called automatic bread slice oven and bread toaster in my country. It is an electric cooking utensil specially used to re-bake sliced bread. Using it, not only can the slices of bread be toasted into a burnt yellow color, but also make it more fragrant and taste better, and increase appetite. A toaster usually includes a multi-function oven, an insulated oven surface, a special lifting device, etc., and more advanced ones also include a detachable crumb tray.
1. The origin of the toaster
As the staple food of human beings, bread comes in various shapes and sizes. Therefore, it is inconvenient to eat, which also leads to the evolution of the way of eating bread. So someone cut the bread into slices for easy eating. Bread slicers emerged due to the uneven shape and thickness of hand-cut bread slices. Moisture in sliced bread is often the main factor inducing spoilage in sliced bread. In order to prolong the shelf life of a slice of bread, the moisture inside the slice of bread must be removed.
Therefore, people hundreds of years ago used sticks, knives, swords and other utensils to penetrate the slices of bread and bake them on an open fire. Later, the slices of bread are baked in the hearth, so that the heat radiation can directly act on the slices of bread. When the surface of the bread reaches 310 degrees Fahrenheit, the sugar and starch begin to turn a brownish-yellow color and give the bread a burst of aroma. The baked bread slices are golden yellow, crispy on the outside and soft on the inside. The taste has also been greatly improved. So toasting slices of bread has long been a common culinary habit. The earliest tool specially used for toasting slices of bread was the bread slice baking rack that appeared more than two hundred years ago. The front end of this baking rack has two clamping handles, which are used to clamp two slices of bread. When the rack is pushed into the hearth, the slices of bread are ready to be toasted.
The bread slice baking rack needs to be toasted with an open flame, and someone needs to take special care of it during toasting. These shortcomings undoubtedly bring inconvenience to daily family cooking. The presence of open flames also creates some safety hazards. In order to make daily family cooking more convenient and safe, bread baking technology produced a revolutionary progress in the early 20th century, namely the intervention of electric energy. The first successful electric toaster was designed by American Frank in 1909.
2.The functional characteristics of the toaster
The only function of the toaster is to bake bread. Due to its ingenious design, it highlights the specialization of toaster baking. The bread it bakes is different, it is all-round, and the taste is more authentic and delicious. For example, it can adjust the baking degree, defrost and then bake, and reheat, and there are many toasters. Advantages, it is small in size, convenient and safe to use, and its power is smaller than that of an electric oven, saving electricity. The bread baked in the toaster is crispy and can be prepared with different textures. Breakfast at home is often toast with a glass of milk. After the ordinary square buns are baked, you can add peanut butter, milk or cheese according to your own taste. With the development of society, small household appliances have gradually entered the lives of citizens. It can be seen that the lifestyle of citizens is gradually changing, and it is different from before. People will enjoy life more easily.
A toaster is an electric heating appliance specially designed for toasting sliced bread. Bread slices are reprocessed in a toaster oven, which can produce a coking reaction on the surface. Turn the color of bread slices into golden yellow, produce a good taste and stronger aroma, and promote appetite. The source of the name of the toaster is the direct transliteration of its English name Toaster, which was first called in Hong Kong and other regions. In the mainland of my country, it is customary to call it an automatic bread slice oven, bread toaster, etc. The main function of the toaster is to toast slices of bread. But there are also other toasters with functions such as keeping warm and steaming. The toasters studied in this article refer only to models with a single toasting function.
Toasters are heating appliances. Its function is to generate enough heat near the slice of bread to toast it. Breakfast wouldn't be as rich as it is today without a pop-up toaster. Its functions are different, and can be divided according to the bread placement method, function adjustment method, and control structure. Generally, you can see the jump-up, automatic-manual adjustment, and time-controlled toasters.
3. The scheme principle of the toaster
The basic principles of a toaster application are simple. It uses infrared radiation to heat a slice of bread, put it in, and when you see the coils turn red, that's the coils producing infrared radiation that gradually dries and chars the surface of the bread. Electric pop-up toasters mostly work on the same mechanism. First, place slices of bread, frozen waffles, toaster strudel, or other similar items through the slot in the top of the toaster into the tray. Next, use the lever on the side of the toaster to lower the carriage into the chassis.
When the tray reaches the bottom, the tray latch will close and an internal switch will be activated to start the heating process. During this process, the thermostat will determine the length of time that current is delivered from the power cord to the heating element. When setting the thermostat, the operator of the toaster can use the control knob or lever to adjust the toasting cycle. Once the set temperature is reached, the heating process is terminated, at which point the solenoid turns off the power and releases the locking tab, allowing the carriage to pop out and return to its original position. At this time, the operator of the toaster can conveniently take away the toasted food.
4. How to use the toaster
With a toaster, put slices of bread bought the next day into it, and you can enjoy a nutritious breakfast with your family in just a few minutes. Can bake 2 slices of bread at the same time (bread machines can only bake 2 slices in general). Its usage steps are as follows:
1. Use the toaster on a flat, clean, fixed surface!
2. Turn on the power, press the "Switch" function key, and set the "Bread Color Controller" to the "3-4" position. After about 120S, the baking is complete and you can eat it.
3. After selecting the degree of toasting, put the bread into the notch, and press the function key "Switch", any notch can be used to toast a piece of bread.
4. Once the selected baking level is reached, the bread will pop out automatically.
5. During the baking process, press the cancel button to stop the baking.
6. If the bread is stuck, please disconnect the power first, and then take out the bread. (Never use metal objects to remove slices of bread while the power is on)
5. Common fault analysis of toaster
In many homes, toasters are more prone to failure than any other small appliance. There are two reasons for this. First, toasters are generally cheap to manufacture and inherently low quality. Second, when a toaster fails, it's often not the fault itself, but food particles that interfere with its normal operation. If there are too many slices of bread stacked on the tray, the crumbs they create when the tray moves will fall into the bottom of the toaster and accumulate, which will block the tray movement, short the heating element, and block the loose locking plate. open the device and affect the function of the solenoid.
This is why most pop-up toasters have a large crumb tray with a door on the bottom. By sliding or opening this crumb door, food particles that have accumulated on the bottom of the toaster can be removed. For a toaster that is used every day, this job needs to be done weekly. It's as simple as unplugging the toaster, holding the toaster over the trash can and opening the crumb door. After most of the food particles have been poured out, the toaster should be shaken to remove any other particles that may be stuck on the edges. Also, use a can of compressed air to periodically clean out the toaster, but be careful not to damage the sensitive heating elements or switches.
