QUICK FOOD FREEZER IMPROVED TO BE ABLE TO PREDICT FREEZING TREATMENT-FINISHING TIME

摘要

PROBLEM TO BE SOLVED: To predict a time required until the quick freezing treatment of a food is finished. SOLUTION: This quick food freezer having a neural network is characterized in that the neural network receives a signal transmitted from a data-treating means for treating signals transmitted from a temperature-sensing means, and a signal related to the information of a plurality of time intervals, for measuring elapsed times for lowering from a constant temperature to other temperatures and calculates information related to a prediction time trrequired to lower the inner temperature of a food to be frozen to a lower prescribed temperature Tccorresponding to a food phase transfer process; and the data-treating means receives information related to the prediction time trfrom the neural network and calculates information related to a prediction time tnrequired to lower the food temperature detected with the temperature-sensing means to a lower defined final temperature than the phase transfer process temperature Tc, on the basis of the information.
