The vessel used includes, but is not limited to, a microwave digestion tube, a normal pressure digestion tube, a volumetric flask, a beaker, a test tube, etc.

At present, common cleaning means comprise acid cylinder soaking, microwave digestion instrument blank program cleaning, acid steaming cleaning and the like. Among them, the acid steaming cleaning has the best cleaning effect. The acid steaming cleaning method is that the utensil to be cleaned is reversely buckled on a steam guide pipe or a support rod, then a cover is covered or a door is closed, a heater is started to heat acid liquor to generate acid steam, and the acid steam rises to clean the inner surface of the utensil to be cleaned. The main disadvantages of the existing acid steaming cleaner are that:

1. the heater heats the cleaning cavity, energy needs to be transmitted to liquid through the cleaning cavity, the acid steaming cleaner is mostly made of acid-resistant material Polytetrafluoroethylene (PTFE), the heat insulation performance of the material is particularly good, and the liquid preheating speed is low;

2. in the drying stage, the dishes are dried using heated hot air. Because the air flow rate is high, the air cannot be heated to the ideal high temperature, and the hot air has a large energy loss from a heat source to the surface of a vessel, the energy absorbed by the liquid is relatively little, and the drying effect is seriously influenced;

3. the steam is unevenly distributed, the closer to the heater, the higher the acid liquid temperature and the steam amount, and the farther from the heater, the smaller the steam amount, and the same is true for the air distribution in the drying stage. This results in the same batch of ware, with different cleaning and drying effects due to different placement locations.

Therefore, an acid-steaming cleaning device which can accelerate energy conduction and has uniform energy distribution is particularly desired.
