General
Amongst
the many possible applications of RUBITHERM PCM's, the concept
of improving the temperature retention of food during the period between
meal preparation and delivery to the customer, is receiving increasing
attention. The European Hazard Analysis and Critical Control Points (HACCP)
guidelines call for self measurement and a strict control of the minimum
temperature of 65 °C for heated food. The food delivery industry often
finds it very difficult to meet the requirements of the guidelines if,
for example, transport is delayed, or the outside temperature is very
low or the insulated transport box is opened numerous times to take out
some meals. Furthermore, overheating and consequently further cooking
of food should be avoided.
Heat storage elements
The RUBITHERMŽ heat storage elements are an excellent supplementary heat source for insulated transport boxes and bags that are used to transport hot food. Our ecological latent heat granulate RUBITHERM GR 80 is incorporated into the elements. This considerably improves the temperature retention time, utilising the advantages of the latent heat storage process: high heat storage capacity and nearly constant temperatures during the phase change process.
- high thermal energy storage capacity at a relatively constant temperature level, thus providing long temperature retention periods
- heating of the elements in a conventional thermofan /convection oven
- easy handling: the hot elements are placed in an insulated box or bag just before the meals are included for transport
- slow release of stored heat energy to the food - without overheating and consequently further cooking
- sealing of the PCM in suitable materials (aluminium or plastic profiles) means that health requirements are easily met
- elements can be hygienically cleaned
- long-life product, provided proper handling is maintained
- numerous element shapes and forms are available; electrically heated elements are also feasible
