Due to the particularity of the tobacco industry, its sensory evaluation training room meets the standard conditions (YC / 291-2009), so the cost of building a separate training room and assessment room is relatively high. Generally, training and assessment are concentrated in the same room. However, when conducting skill training, all technicians need to see the podium and screen, and the distance is close to facilitate discussion; when conducting skill assessment, each technician should be isolated from each other to prevent mutual influence and cheating.

[0003] When conducting visual tobacco evaluation training, the tobacco raw materials need to be spread out on the workbench to observe the color, veins, etc. of the tobacco raw materials; when conducting visual tobacco evaluation assessments, the invigilator needs to observe each technician to prevent them from assisting the evaluation through taste stimuli such as trial and error.

[0004] When conducting training on tobacco evaluation in terms of smell and taste, tobacco products need to be evaluated and identified, and the smoke produced needs to be discharged to the outside in a timely manner. However, when multiple people evaluate tobacco multiple times, some components in the smoke produced can remain in the air or on the surface of objects for a long time, especially at the mouth of ventilation ducts and the surface of grilles, and are not easily removed by suction devices, causing the evaluation technicians to be affected by the retained smoke components, resulting in inaccurate tobacco evaluation results. At the same time, it is necessary to shield the technicians' visual perception to prevent them from assisting in the evaluation through color, veins and other characteristics.

[0005] The sensory evaluation training room in the prior art cannot meet the conditions of training and assessment at the same time. Summary of the invention
