Applications in which the Computation Function is Used

Monitoring the Sterilization Process during Food Manufacturing

When sterilizing preserved foods by heating, bacteria must be completely annihilated without changing the
heat of the product (a degradation of the taste). In most cases, the integrated fatality (F value) must be
recorded and monitored. By using the computation function of the DX Series (relational computation, four
arithmetical operations, and exponential computation), the F value can be calculated and recorded.

*F value
The integrated fatality of the bacteria obtained by heat sterilization. It is the integrated value of the fatality
rate (Li) of the bacteria per unit amount of time (

Δ

t), and Li is a function of the sterilization temperature.

If the Ti is constant, the F value per unit amount of time (

* Constant K2 to K5 may vary depending on the conditions.

CH1 (measurement channel): Food temperature measurement

Define the fatality rate Li of the bacteria (equation

) in computation channel CH31.

CH31 (computation channel): 31: K1 ** ((1 - K3) / K2)

Define the F value (the integral value of the bacterial fatality rate LI per unit time

When the food temperature falls to 100
