A rice cooker or rice steamer is an automated kitchen appliance
designed to boil or steam rice. It consists of a heat source, a cooking bowl,
and a thermostat. The thermostat measures the temperature of the cooking bowl
and controls the heat. Complex rice cookers may have many more sensors and
other components, and may be multipurpose. Cooking rice has traditionally
required constant attention to ensure the rice was cooked properly, and not
burnt. Electric rice cookers automate the process by mechanically or
electronically controlling heat and timing, thus freeing up a heating element
on the cooking range that had to be otherwise occupied for rice cooking.
Although the rice cooker does not necessarily speed up the cooking process,
with an electric rice cooker the cook's involvement in cooking rice is reduced
to simply measuring the rice, preparing the rice properly and using the correct
amount of water. Once the rice cooker is set to cook, the rice will be cooked
with no further attention.
Features:
For modern home
rice cookers, the smallest single-person model cooks 1 rice cup (180 ml),
whereas large models can cook 10 cups. Commercial models can cook 20 or more
cups. As a possible source of confusion, model specifications and names may
list either cooked or uncooked capacity. Rice roughly doubles in size during
cooking; therefore, a 10 cup (uncooked) rice cooker can produce up to 20 cups
of cooked rice. The prices vary greatly, depending on the capacity, features,
materials used, and the country of origin.
The majority of
modern electric rice cookers are equipped with a stay-warm or keep-warm feature,
which keeps the rice at an optimal temperature for serving without over-cooking
it. Some gas cookers also have electric stay-warm mechanism. However, the
usefulness of this feature degrades over time, a microwave may be more energy
efficient or better suited to reheat rice that will sit longer than four hours.
Some rice
cookers use induction heating, with one or more induction heaters directly
warming the pot. This can improve energy efficiency.
Most modern
rice cookers use aluminium for the inner cooking bowl. There are some models
that use stainless steel instead of aluminium. Various other materials, such as
copper, pure carbon, ceramic, and diamond powder coating, may be used for
higher heat conductivity or better taste.
The
pressure-cooking models can raise the water's boiling point higher, e.g., from
100 °C at 1.0 atm up to about 110 °C at 1.4 atm, which speeds cooking. The
pressure-cooking models can also be used in high altitude areas, where the
boiling temperature is below 100 Celsius. Pressure cookers are also suitable
for cooking brown rice (which contains oils and bran fiber that cook
differently from pure white rice starch). Some pressure rice cookers have a
varying pressure control mechanism (named the "dual-pressure" method)
that creates repeated pressure/release cycles during the cooking.
There also
exist mechanisms to collect and return the boiled over liquid to the inner rice
bowl.
Many cookers now have microprocessor-controlled cooking cycles, which are often used to adjust for rice and
cooking type.
Applications
Rice cookers are typically used for the preparation of plain or
lightly seasoned rice. Each rice cooker model may be optimized to cook a
certain type of rice best. For example, most Japanese rice cookers are
optimized for cooking Japanese rice and may not be the best for other types of
rice[citation needed], although cooking time can be lengthened simply by more
water.
The typical method of cooking long grain rice
is boil-and-strain and/or steaming method. The absorption method used in
Japanese rice cookers will produce slightly different texture and taste,
usually stickier rice.
Brown rice generally needs longer cooking
times than white rice, unless it is broken or flourblasted (which perforates
the bran).
Different varieties of rice need different
cooking times, depending on their grain size, grain shape, and grain
composition. There are three main types of Asian rice: Oryza sativa subsp.
indica, i.e., Indian rice (long grain rice, e.g., basmati rice and Thai jasmine
rice), O. sativa subsp. javanica, i.e., Java rice (large grain rice) and O.
sativa subsp. japonica, i.e., Japanese rice (medium grain rice, e.g., Calrose
rice, short grain rice, e.g., most Japanese rice and risotto rice).
African rice, Oryza glaberrima, is an entirely
separate species, but can be cooked in the same way. Zizania is not even in the
same genus, although it is often called a rice (or "water oats"); it,
too, can also be cooked in a rice cooker.
A
rice cooker can be used to cook many boiled or steamed granular foods, such as
pot barley, bulgar wheat, and dal. Provided the ingredients have similar
cooking times, a rice cooker can cook mixtures such as khichdi. Some rice
cookers can be used as automated couscoussiers, cooking couscous and a stew
simultaneously.

It is estimated that in 2015, the scale of information consumption will exceed RMB 3 trillion, driving more than 1.2 trillion yuan of new output in related industries; the new type of information-based Internet consumption will reach 2.4 trillion yuan, an average annual increase of more than 30%. Under the current development pattern of the new normal, smart TV is becoming younger and younger and becomes the center of an open family life platform.
From the TV itself, although it is a "bone-sized" consumer electronics product, it is still young. As the closest consumer electronic product to people's family life, TV has never stopped the pace of innovation: from the flat, 3D, smart, 4K to today's home smart terminals and portals, there are not many industries have experienced more than 30 years of development, or Still young; the current television graft on smart and the Internet will create more possibilities, will be more exciting, and the prospect is endless.
There was a period of time when people thought that the emergence of personal terminals such as smart phones and tablet computers had made televisions increasingly marginalized. However, with the arrival of the era of television intelligentization and interconnection, this industry has added new vitality. Home terminals based on smart TVs have become an important carrier for home entertainment and information control. The future will not only disappear, but on the Internet. It becomes more powerful under the armed forces. In this process, the television industry will start a new journey, including the integration process of content and channel broadcast, the process of multi-screen interaction and family socialization, the analysis of user behavior based on big data, and accurate content, advertisements, and application recommendations. The process, as well as the development of multi-functional and business models of television from single video playback to information browsing, game entertainment, full education, online shopping, etc.
From the TV industry, there will be "dinosaur-scale" behemoths in the development process, but ultimately it will be based on cross-border cooperation and open and shared ecological chain innovation. The connotation and extension of the TV industry have undergone revolutionary changes. For example, the products consumed by users are no longer limited to audio and video content, but are extended to e-commerce, games and other pan-entertainment and pan-family products; business models also appear free of charge. + Variety of value-added services, users watching broadcast content is just the beginning of value realization, and so on. In this process, different companies in the industry have made continuous breakthroughs through self-breakthrough innovations, as well as vertical and horizontal linkages between different companies and even ecological chain innovations. Exclude individual companies from relying on their own strengths to create a relatively complete, self-directed, relatively closed-end system and become an industry giant. However, Internet + this thinking principle will bring a fundamental transformation of business thinking to the television industry: users are the center, cross-border cooperation in the ecological chain can ultimately promote consumption upgrades, leading the industry transition. In this new era, we no longer believe in the traditional “law of the jungle†as a strong, strong food, and it is more advocating the “law of the sky.†All companies in the same sky, the dimensions of survival do not completely coincide. Faced with a considerable piece of cake in the smart TV industry, this is a unique industry that involves multiple stakeholders. It requires the participation of licensees, content providers, hardware manufacturers, and internet giants to make a difference.
In the entire smart home industry, smart hardware will continue to be produced by "killer" single products or applications, but television will certainly be a platform-level smart product. With the official commercial use of 4G in China in 2014, networking (internet and mobile Internet) consumer electronics products and revolutions are in full swing in China. In 2015, many smart life devices are shining brightly, smart watches, wristbands, smart glasses, smart running shoes. The various functional products point to different subdivision scenarios and extend the dimensions of smart life. A single "killer" smart life device is very likely to occur, this will be a good thing, it can achieve high-frequency single point of user breakthroughs, the formation of the use of habits; with popular once portable digital cameras and MP3 in the smart phone this platform-level product popularity After that, as soon as it disappears, a single smart hardware must be docked with the platform before it can be durable. For the whole smart home industry, there will not be much platform industry, and TV must be one of them.
As a home networking intelligent terminal platform, TV should have its historical inevitability. Because television has the attributes of family social networking, there are properties of networking, and there are also business model extension properties. With the development of triple play, televisions, mobile phones, mobile terminals, and computers must be built on top of multi-screen interaction. The sharing and integration of information between various terminals becomes an inevitable trend; at the same time, the convergence of various terminals Sharing with information is not only content sharing, but also sharing in terms of processing capabilities and interoperability. TV terminals have unparalleled advantages in terms of hardware platforms, system access, and ease of operation.
New industry features have brought new participants. Under the dream of the living room of the Internet, all links, including terminal manufacturers, technology vendors and even content providers, have sought to become the main operators and have become the main players in the platform's entrance. This industry is large enough to accommodate more of our imagination, can achieve more industry chain connection, technology transformation, business opportunities, foster and stimulate China's information consumer market, and further promote the transformation and upgrading of China's electronic information industry. 
TV is young and will become an open smart home life platform center
