A heating vent law
  (1) when the contents are heated to a certain temperature hot canning, immediately sealed.
  (2) the contents of the canning added sugar, after the center exhaust box is heated to the temperature of the tank to meet the requirements, and immediately sealed.
Exhaust gas temperature and time, depending on the species, type of tank and the injection of sugar tank temperature anomalies. General exhaust tank temperature is 82 to 96 degrees, time 7 - ~ 20min, to seal the front center of the tank temperature reaches the specified requirements shall prevail.
    Heating the exhaust gas temperature is higher, the longer the time, the food composition in the tank, and air is excluded, the more, the higher the degree of vacuum inside the tank sealed. But the high exhaust temperatures can lead to soft tissue tank surface rotten flesh and sugar spill, while too high a vacuum sealed tank deflated cans also easy to cause the phenomenon. The degree of vacuum in general mostly canned fruit 0.027 ~ 0.04MPa.
Second, the method of vacuum sealing machine vacuum exhaust ventilation is applied to seal canned fruits. For air content and materials, if the vacuum sealing machine is too high, sugar is often easy to make the tank is withdrawn too low degree of vacuum is often canned finished lower. Therefore, apple, pineapple and other fruit canning treatment should be preceded by vacuum suction or vacuum heating solution or syrup added to compensate for the lack of vacuum sealing machine after canning.
