constructing the adjustment model comprises the following steps:
the process is a low temperature drying stage, in which the temperature is 45-60 ℃, the stage can continue drying with steam, and the steam of the stage does not cause daylily to absorb water. Meanwhile, the steam recovery structure recovers low-temperature steam, so that the temperature stability of the interval can be kept, and reasons for abnormal point positions in the interval include:
too high a steam temperature, too low a steam temperature and too high a humidity;
if the weight change is small, it is considered that the humidity is too high, the temperature is too low or both; at this time, the recovery amount of the steam recovery structure is adjusted to recover the steam, and in the process, the heat of the drying chamber can partially enter the de-enzyming chamber, so that the humidity is reduced, and meanwhile, the temperature is increased to ensure proper temperature.
If the weight change is large, the temperature is considered to be too high; too high a temperature can lead to rapid water loss, which can lead to distortion of appearance and embrittlement in the later drying process. Therefore, the actual air output of the air outlet is reduced, and the entry of high-temperature steam is reduced.

the process is a high-temperature drying stage, the water content of the day lily is between 30 and 40 percent, the water content is low, the process can cause the day lily to brown, and the phenomenon of brittle fracture of the day lily can be caused by too fast water loss. Too slow water loss can lead to incomplete drying and affect subsequent preservation. The two cases are the existence of abnormal points on the secondary prediction curve.
The construction of the secondary adjustment model comprises the following steps:
if the weight change is large, the temperature is considered to be too high, the actual air output of the air outlet is reduced, and the high-temperature gas inlet is reduced.
And if the weight change is small, the temperature is considered to be too low, the actual air output of the air outlet is increased, and the high-temperature gas inlet is increased.
The latter sets of weight data, such as (G11, G12, G13, G14, G15) are fitted to the quadratic prediction curve to obtain the actual moisture content variation curve,
extracting abnormal point x in actual water content change curve 1 ,x 2 ,x 3 …x n Let x be j For suspected data, an outlier was found:
and find not to include
Standard deviation estimator:
inquiring the t test coefficient table according to the measured data n and the selected significance alpha (generally 0.05 is selected) to obtain a test coefficient K, if
Suspected data x j Contains coarse errors and should be eliminated, otherwise this data is preserved. And then sequentially judging the rest values until no new coarse error value appears, wherein the rest measurement data are normal measurement data, fitting the point positions with the coarse errors removed into the curve to obtain a new actual water content change curve, comparing the new actual water content change curve with a standard model, judging whether the new actual water content change curve meets the standard, and if not, giving corresponding hanging basket calibration.
