Definitions

  • the present invention generally relates to a cooking apparatus, and more particularly relates to an electric cooking apparatus and method for cooking low starch food item by draining out the starch water after cooking in order to cook low calorie food item.
  • Rice is the main food of approximately 60% of the earth's population.
  • the starch may be categorized into amylose and amylopectin wherein amylose dissolves in the water when rice is being cooked while amylopectin is gelatinized after the rice is being heated. Therefore, the conventional rice cooker would not be able to cook rice in such a way that the starch content is reduced. In order to lower the amount of starch content in the cooked rice, rice may be cooked with more water and after rice gets cooked the extra starch water can then be drained away and thrown.
  • US patent publication, 2007/0190221 disclosed a method and an apparatus for healthy rice cooking and removing starch in rice is disclosed.
  • a rice cooker including an inner pot, an outer case with control buttons, power input terminal, a thermostat component, a control circuit, a rice cooker lid and a heater plate.
  • the inner pot is placed inside the outer case; the heating plate, the thermostat and the control circuit is placed at the bottom of the inner pot.
  • a starch removing device is placed between the bottom of the inner pot and the outer case, the starch removing device comprises: a heating plate, power input terminal, a thermostat component, a control circuit disposed at the bottom, a medium case inside the outer case, a water storage trough at the exterior of the medium case, a water drainage trough between the medium case and the outer case, and a evaporating tube at the bottom of the water storage trough; the ends of the evaporating tube is connected with the water storage trough and the inner pot through channels, the water drainage trough is connected with a valve and the bottom of the inner pot through channels.
  • the valve is mounted within the casing and it would seem that the most feasible way to actually remove the valve for regular cleaning would be to dismantle the rice cooker.
  • the disclosed apparatus is complex in structure to users who are not electrical appliances savvy.
  • Malaysian patent publication MY-20030968-P disclosed yet another rice cooker with a means to discard water through a vacuum tube and a vacuum pump unit.
  • the vacuum pump does not provide the most effective way to discard the water because the vacuum tube is merely located at one side of the rice cooker. Therefore, the vacuum mechanism would only end up extracting starch water from one side of the rice cooker causing uneven starch content throughout the cooked rice. Furthermore, having a vacuum pump would require more power as water is being sucked out against gravity. A vacuum pump can also be very audible could be displeasing to the users' hearing.
  • US patent publication, 2014/0044849 A1 disclosed an apparatus for cooking starchy food with significantly reduced starch content by regulating the draining of the water from the apparatus before the food is fully cooked using a two layered containers with outer layer having a hollow section, inner laying having perforation to hold the food and water, the hollow section having a steel ball to stop the flow of water from outer container to drainage container under normal condition.
  • the steel ball is regulated via an electromagnetic device to slid away and clear the hollow section to drain the starch water.
  • this invention needs user to clean up two containers which are used for cooking (inner & outer container) and also the steel ball. Further this invention always needs maximum quantity of water to be used as the cooker doesn't have a mechanism to differentiate between the time of cooking for different quantities of rice.
  • US patent publication, 2005/0120887 disclosed yet another rice cooker with the capability to discard water using a solenoid valve with a manual override lever.
  • the solenoid valve and the manual override lever are accommodated at the base of the inner pot.
  • the valve is mounted within the rice cooker and it seems that the only way to clean the valve is to detach the rice cooker itself which would be cumbersome.
  • the valve provided has a very thin duct which allows water to be discarded as individual drips from the rice cooker. The water cannot be eliminated effectively due to the size of the duct also because atmospheric pressure may prevent the water from being continuously discarded.
  • the invention includes a manual override lever that is contained within a water reservoir and cannot be manually controlled by the user as there are no perforations at the water reservoir to allow access to the user to control the lever. There is also no indication that the lever is controlled by some electrical means.
