Abstract: A real food honesty display system including at least one on-site recording device, a central electronic device, at least one remote electronic device, and a network. The on-site recording device is disposed in at least one ecological environment for capturing a dynamic videos of animals, generating a geographic information showing a position coordinate, and combining the dynamic video with the geographic information to form an information set. The central electronic device is for receiving the information set and transmitting the information set to the remote electronic device. A first and a second random numbers are generated by a random number generator and a second processor of the central electronic device corresponds the first random number to the information set and coverts the second random number to a code corresponding to the information set. The remote electronic device reads the code to display the information set corresponding to the code.

Abstract: A real food honesty display system contains: an electronic device, a record on spot device, and a field service device. The electronic device includes a processor configured to construct an independent random number and a pseudo random number which are updated based on a change of dynamic image of geographic information. The record on spot device includes a communicator. A field verification is executed by the record on spot device by using the geographic information, and a live transmission of a cultivation of an ecological structure of the dynamic image is executed. The field service device is configured to read the pseudo random number and includes a communication module built therein and connected with a hermetic package of the electronic device of the mesh network so that the independent random number and the pseudo random number are combined to the random number.

Abstract: A sterilization method of a food cooling device employing a temperature difference effect, includes a sterilizing space to accommodate energy conductive tubes with cold water within and a steam transited to the sterilizing space for a fast temperature difference phenomenon and further a temperature difference effect created by low-temperature fluid inside and steam outside the energy conductive tubes in which the temperature difference effect strengthens lethality to colon bacillus or Salmonella and separates residual food from the energy conductive tubes' walls for cleaning effectively delivered by the energy conductive tubes and food healthily processed by the food cooling device.
