Three-dimensional cooking machine

A three-dimensional cooking machine, comprising:

• a control computer for storing image files of plural predetermined food models and outputting a control command corresponding to the image files of the plural food models;
• and
• plural food ingredient laminating devices, wherein the plural food ingredient laminating devices are controlled to perform three-dimensional food laminating operations simultaneously according to the control command from the control computer, so that plural dishes are prepared by the plural food ingredient laminating devices simultaneously, wherein each of the food ingredient laminating device comprising an ink-jet printer, and the ink-jet printer comprises:
• a working platform;
• a movable carrying mechanism;
• at least one printhead for ejecting a food ingredient, wherein the at least one printhead comprises a printhead platform, a food ingredient supply tank and a pressure regulator, wherein the food ingredient supply tank is located over the printhead platform and contains the food ingredient, and an internal pressure within the food ingredient supply tank is adjusted to be maintained at a negative pressure by the pressure regulator, wherein the printhead platform comprises a printhead chamber and plural nozzles, the plural nozzles are located under the printhead chamber, the plural nozzles are in communication with the printhead chamber, and the food ingredient supply tank and the pressure regulator are in communication with the printhead chamber, wherein the plural nozzles eject ink drops configured to be controlled to comply with the following conditions:
• a volume of each ink drop is in a range between 0.1˜20000 picoliter, a diameter of each ink drop is in a range between 0.05 and 200000 picometer, a volume error of each ink drop is 20%, and an ejection rate of each ink drop is in a range between 0-10000 drops/second;
• and
• at least one base disposed on the working platform, wherein the movable carrying mechanism is located over the working platform, and movable along two horizontal axis directions and a vertical axis direction according to the control command from the control computer, wherein the at least one printhead is supported on the movable carrying mechanism, and freely moved along the two horizontal axis directions and the vertical axis direction to eject the food ingredient from the plural nozzles on the at least one base so as to produce a three-dimensional food product by laminating multiple layers of the food ingredient.

A three-dimensional cooking machine, comprising:

• a control computer for storing an image file of a predetermined food model and outputting a control command corresponding to the image file of the food model;
• and
• a food ingredient laminating device comprising a construction chamber, a powder spreading mechanism and an ink-jet printer;
• at least one printhead for ejecting a food ingredient, wherein the at least one printhead comprises a printhead platform, a supply tank and a pressure regulator, wherein the food ingredient supply tank is located over the printhead platform and contains the fluidic binder, wherein the printhead platform comprises a printhead chamber and plural nozzles, the plural nozzles are located under the printhead chamber, and the plural nozzles, the supply tank and the pressure regulator are in communication with the printhead chamber, and an internal pressure within the supply tank is adjusted to be maintained at a negative pressure by the pressure regulator, wherein the plural nozzles eject ink drops configured to be controlled to comply with the following conditions:
• a volume of each ink drop is in a range between 0.1˜20000 picoliter, a diameter of each ink drop is in a range between 0.05 and 200000 picometer, a volume error of each ink drop is 20%, and an ejection rate of each ink drop is in a range between 0-10000 drops/second;
• wherein the powder spreading mechanism provides a powdery food ingredient to the construction chamber, and the ink-jet printer ejects a fluidic binder on the powdery food ingredient according to the control command from the control computer, so that the fluidic binder and the powdery food ingredient stick together to form a single layer structure matching a cross section profile of the food model, wherein the powder spreading mechanism further provides a powdery food ingredient to a solidified single layer structure in the construction chamber, and then the ink-jet printer ejects a fluidic binder on the powdery food ingredient in the construction chamber according to the control command from the control computer, so that the fluidic binder and the powdery food ingredient stick together to form another single layer structure matching another cross section profile of the food model, wherein a three-dimensional food product is produced by laminating multiple single layer structures, wherein according to the control command from the control computer, the fluidic binder is ejected out form the plural nozzles to the powdery food ingredient in the construction chamber, wherein after the fluidic binder and the powdery food ingredient stick together to become solidified, the single layer structure matching the cross section profile of the food model is produced.
