XH-106-1RW Food Sulfur Dioxide AnalyzerPurpose: Distillation pretreatment for detecting residual sulfur dioxide in food and other items

1Technological innovation points:

XH-106-1RW Food Sulfur Dioxide Analyzercontain:Heating control unit, built-in cooling water self circulation unit, intelligent control unit for distillation endpoint, anti backflow protection unit, steam condensation unit.

1. The heating device adopts bowl shaped far-infrared ceramic vessels suitable for round bottom flasks, with high thermal radiation efficiency, low power consumption, and single hole heating power ≤400W；

2 The heating area is designed with insulation to prevent heat loss and ensure even and stable heating of the sample;

3 The heating system should be designed with micro boiling and full boiling control modes, automatically controlling the heating rate according to different sample boiling points to ensure stable distillation experiments and controllable sample boiling phenomena;

4 The host includes a built-in cooling water tank (approximately30L）The cooling cycle system (compressor refrigeration) is integrated as a whole,

5 The host is equipped with a rotary flow meter that can adjust the nitrogen flow rate through a single hole. The flow rate control range is:60-600ml/min；

6The distillation endpoint control unit adopts pressure sensor control technology, which can independently set the volume or weight of the distillate in each well, realizing intelligent distillation operation with a range of1-500mlBetween;

7 After distillation, there will be sound and light alarm prompts.

8 To improve distillation efficiency, the steam area and cooling area should be designed separately, with the steam chamber located on the outside of the cooling water chamber and using double-layer vacuum technology. The upper part of the condenser tube should be equipped with a grinding plug for easy cleaning of the condenser tube.
