To sum up, have intermittent automatic pan-boiling system using the corresponding brix value of corresponding Liquid level by the way of to boil it is sugared into
Row automatically controls, but because level gauging is inaccurate, microwave concentration meter cannot use reliably and with long-term and it is expensive cannot immediately more
The reasons such as cleaning are changed, cause product using effect bad.
