What is a hot board?
Hot board is a small electrical device used in cooking and sometimes in scientific experiments. The origin of the device is unclear, but most reports indicate that it was invented in the first half of the 20th century, when small electronics were available. Hot plates are cheap and are often the basis of hotel and college tracks.
The hot boards mechanics are quite simple. The device is usually powered by an electric plug, which, when connected to the socket, heats the coils inside the hob, similar to the electric burner in the stove. Some newer models have halogen heating that warms much faster than traditional methods. The rest of the hot board can be steel or plastic. Most hot boards have one or two burners and different buttons to adjust the temperature and warning.
In small apartments or studies, hot plates can be an alternative to a large stove. Men furnished individual apartments are equipped with a hot plate and do not allow the stove to install. Although some collegeThe tracks prohibit the use of hot plates due to the risk of fire, many students maintain them regardless of the means to re -heat coffee or make hot snacks.
Cheap motels have long provided hot plates to guests, although many now replace microwaves. In America, some nostalgia surrounds the use of devices in the mid -20th century, and many associate it with long holidays and cheap inn One recent American travel memory written by a higher education professor in 2007 is even called cheap motels and a hot plate: economic travelogue .
Scientists use hot plates to replace the heat source of live flame, such as the Bunsen burner. In 1942, a man from New Jersey named Arthur Rosinger submitted a patent on a magnetic mixer for use with a hot plate. Stirrer works by placing a magnet coated with plasticil in a heating container and at the same time it has a rotatingThe basic magnet under the container. This self -breast technology is often used in chemical experiments.
hot boards are a danger of fire and resulted in many fires and even deaths around the world. These fires can be caused by overheating of the board by random by leaving the on or occasionally by the cooking item burned. Never leave the hot plate unattended and in the case of a disaster, be sure to leave the fire extinguisher with you. Experts recommend that children be allowed to run hot plates unattended by adults.
heating weighs about six to eight pounds (2.7-3.6 kg) depending on the materials used. They differ in price, with one burner models available from only $ 15 (USD) up to $ 400 for an advanced inductive version of the heat. Some newer models look like trays or grids, allowing a larger heating surface usable for more Itepani. As in a hot plate, a tray of warming that has a lower temperature range and food is often usedeats to keep food at the right temperature.
