Patents by Inventor David Kung-Tin Shao

David Kung-Tin Shao has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12053006
    Abstract: A method and apparatus is disclosed relating to food preparation in commercial kitchens and food processing plants. The disclosed extreme vacuum cooling (EVC) technology and apparatus can work in ultra low pressure conditions with adaptive pressure control to avoid potential liquid splash inside the vacuum chamber caused by un-controlled low pressure conditions. Clean air is added into the vacuum chamber to allow the chamber pressure to track a setpoint trajectory that may have ramp up periods in order to avoid liquid splash events. The apparatus enables the user to cool various kinds of foods quickly, save energy, and meet food safety regulations.
    Type: Grant
    Filed: January 27, 2023
    Date of Patent: August 6, 2024
    Assignee: Culinary Sciences, nc.

  • Patent number: 11638436
    Abstract: A method and apparatus is disclosed relating to food preparation in commercial kitchens. The disclosed extreme vacuum cooling (EVC) technology and apparatus can work in ultra low pressure conditions with adaptive pressure control to avoid potential liquid splash inside the vacuum chamber caused by un-controlled low pressure conditions. Clean air or inert gas is added into the vacuum chamber so that the chamber pressure can track a setpoint trajectory that may have ramp up periods in order to avoid liquid splash events. The apparatus allows the user to automatically cool various kinds of foods based on a recipe with minimal human interaction and meet food safety regulations.

  • Publication number: 20230076811
    Abstract: A method and apparatus is disclosed relating to food processing and preparation in commercial kitchens. The disclosed extreme vacuum cooling (EVC) technology and apparatus can work in ultra low pressure conditions with adaptive pressure control to avoid potential liquid splash inside the vacuum chamber caused by un-controlled low pressure conditions. Clean air or inert gas is added into the vacuum chamber so that the chamber pressure can track a setpoint trajectory that may have ramp up periods in order to avoid liquid splash events. The inventive apparatus allows the user to automatically cool various kinds of foods based on a recipe with minimal human interaction and meet food safety regulations. Different cooling recipes can be created based on the type and volume of the foods and a related vacuum pressure setpoint trajectory. High-volume food service kitchens can achieve less labor intensive, more time efficient, and higher throughput food preparation operations.
