KFC does not sell their original pressure cookers to the general public. The pressure cookers used by KFC and other large restaurant chains are typically commercial-grade equipment, designed and manufactured for industrial-scale cooking.
These commercial-grade pressure cookers are not intended for home use, and they are not available for purchase by the general public through regular retail channels. They are specialized equipment designed to meet the specific needs and volume requirements of commercial kitchens like those in KFC restaurants.
If you are looking for a pressure cooker for home use, there are plenty of options available from various brands that are designed and certified for home cooking purposes. Always make sure to follow the manufacturer's instructions and safety guidelines when using any pressure cooker or kitchen equipment to ensure safe and efficient cooking.
