I found that when the drying time increases to make up the L * and when the Add infrared capacity in step 1 and the hot air temperature in step 3 to make the value L * likely reduced. While a value * and b * values are increased. To increase drying time.
Once found, the drying time was increased, the L * values decrease and increase in infrared steps 1 and air temperature in Step 3 to make the L * a downward trend, while the a * and b. * increased When drying time increases
It was found that when the drying time increases the L * reduced and when the increase in step 1 Infrared and hot air temperature in the process 3 makes value. L * tends to decrease, while the a * and B * increased when drying is increased.
