Cooking apparatus using liquid bath

A system, comprising:

• a container having a bath having an amount of liquid present therein with at least three temperature zones in the amount of liquid in the container, wherein the at least three temperature zones have different selected temperatures for cooking a foodstuff, in the at least three temperature zones, wherein a first temperature zone of the at least three temperature zones is located in a lower portion of the container, a second temperature zone of the at least three temperature zones is located in an upper portion of the container that is above the lower portion, and a third temperature zone of the at least three temperature zones is located in the container between the lower portion and the upper portion, wherein the system includes 1) a first heating or cooling unit disposed at the lower portion of the container to actively heat and maintain the liquid residing in the first temperature zone at a first temperature or a first temperature range in order to cook, cool, or maintain a first portion of the foodstuff, 2) a second heating or cooling unit disposed at the upper portion of the container to actively heat or cool and maintain the liquid residing in the second temperature zone at a second temperature that is higher than the first temperature or a second temperature range that is higher than the first temperature range in order to cook, cool, or maintain a second portion of the foodstuff that is different than the first portion, and 3) a third heating or cooling unit disposed between the lower portion of the container and the upper portion of the container to maintain the liquid residing in the third temperature zone at a third temperature that is between the first temperature and the second temperature or a third temperature range that is between the first temperature range and the second temperature range in order to cook, cool, or maintain a third portion of the foodstuff that is different than the second portion;
• a temperature control unit coupled to the first heating or cooling unit, the second heating or cooling unit, and the third heating or cooling unit;
• and
• a plurality of temperature sensors located within the container for providing feedback to the temperature control unit for the at least three temperature zones, wherein a first temperature sensor of the plurality of temperature sensors located within the container is adapted to monitor the first temperature or the first temperature range of the liquid or the foodstuff present in the amount of liquid in the first temperature zone, a second temperature sensor of the plurality of temperature sensors located within the container is adapted to monitor the second temperature or the second temperature range of the liquid or the foodstuff present in the amount of liquid in the second temperature zone, and a third temperature sensor of the plurality of temperature sensors located within the container is adapted to monitor the third temperature or the third temperature range of the liquid or the foodstuff present in the amount of liquid in the third temperature zone.

A system, comprising:

• a container having a bath having an amount of liquid present therein with at least two temperature zones in the amount of liquid in the container, wherein the system includes 1) a first heating or cooling unit disposed at an upper portion of the container to actively heat or cool and maintain the liquid residing in a first temperature zone of the at least two temperature zones at a first temperature or a first temperature range in order to cook, cool, or maintain a first portion of a foodstuff and 2) a second heating or cooling unit disposed at a lower portion of the container to actively heat or cool and maintain the liquid residing in a second temperature zone of the at least two temperature zones at a second temperature that is lower than the first temperature or a second temperature range that is lower than the first temperature range in order to cook, cool, or maintain a second portion of the foodstuff that is different than the first portion;
• a temperature control unit coupled to the first heating or cooling unit and the second heating or cooling unit;
• and
• a plurality of temperature sensors located within the container for providing feedback to the temperature control unit for the at least two temperature zones, wherein a first temperature sensor of the plurality of temperature sensors located within the container is adapted to monitor the first temperature or the first temperature range of the liquid or the foodstuff present in the amount of liquid in the first temperature zone and a second temperature sensor of the plurality of temperature sensors located within the container is adapted to monitor the second temperature or the second temperature range of the liquid or the foodstuff present in the amount of liquid in the second temperature zone.
