Blue Toaster

The toaster such as a blue toaster is a small kitchen appliance meant to toast bread and other similar kinds of food. Perhaps the oldest kind is the one with two slots for toasting two slices of bread. Typical two-slice toasters need between 600 and 1200 watts to toast bread in three minutes or less. There are also the kinds which are not electrically powered and instead toast bread over an open fire or flame.

Modern toasters fall under three major categories, namely pop-up toasters, toaster ovens, and conveyor toasters. Pop-up toasters—also known as automatic toasters—are toasters that have vertical slots where the slices of bread are to be inserted. Parallel to the slots are its vertical heating mechanisms. On the side of the toaster is a lever which, when pushed up, activates the toaster. When the internal device senses that the breads are already toasted, the toaster automatically turns off and pops the bread out. The earlier version of the toaster used a mechanical clockwork timer instead of a sensor, which could be adjusted to set the toasting degree of the toaster. In the 1930s and the years after that, the later versions of the toaster like the blue toaster already made use of a thermal sensor, which was a much better and more responsive to the actual temperature of the toast when determining the toasting degree.

Toaster ovens on the other hand are miniature ovens that have a door and a tray inside much like regular ovens. To toast food inside a toaster oven, the user has to open the door, place the food inside on the tray, close the door, and then activate the toaster. When the toasting is complete, the toaster will turn off automatically, and then usually a sound will signal the user that it is done. However, compared to popup toasters the user has to open the toaster oven door manually to get the food out.

In general, toaster ovens can perform the same functions of electric ovens but on a much smaller scale. These devices can toast bread with toppings, such as small slices of pizza, garlic and buttered bread, or bread topped with cheese. Toaster ovens however are more likely to produce uneven toasts since their heating components are far from the toast, and the tray acts as a form of barrier between the toast and the heating component located below. Conveyor blue toasters are the toasters that have a more commercial function and are often used in the catering industry. This is because they are designed to toast many slices of bread—approximately 350-900 slices—in an hour and are ideal for bakeries and restaurants. There are however domestic versions of such devices which date as far back as 1938. The more advanced toasters and toaster ovens of today’s time make use of computer-controlled mechanisms instead of electromechanical controls, but they still maintain their compactness and are still considered as tabletop appliances, although there are those kinds that can be hung beneath cabinets.

Blue toasters have become an essential part of the kitchen, and with the advent of new technologies, they are also continuously being improved. Some can even be used to defrost frozen foods, whereas others, with the right permanent modifications, can be used as a reflow oven to melt and solidify toxic solder.
