A portable enteral feeding apparatus facilitates ambulatory enteral feeding and prevents damage to an enteral feeding tube during use. The method essentially consists in: incubating, during 30 seconds to 2 hours, at a temperature less than 80 C. Each connecting slice connects the corresponding prong of the rotatable rack with the corresponding conductive terminal. This makes it possible to dispense with the installation of an additional antenna, generally of a large volume, that is optimized for transmitting and receiving operations.
