Abstract: In order to reveal the influence of ambient temperature and humidity on the processing quality, the influence and application of ambient temperature and humidity in primary processing on tobacco moisture content between key processes were systematically studied. The results showed that the indoor ambient temperature of primary processing was significantly higher than the outdoor ambient temperature, and there was a strong positive correlation between them; the closer to the outside, the outdoor ambient temperature and humidity were more affected by the indoor ambient temperature and humidity. Under the conditions of the primary processing, the ambient humidity had a strong negative correlation with the tobacco moisture content between loosening and conditioning process and tobacco casing process, and the correlation coefficient was -0.705 3; the ambient temperature had a strong positive correlation with the tobacco moisture content between tobacco casing process and drying process of cut tobacco, and the correlation coefficient was 0.831 4; the influence of ambient temperature and humidity on the tobacco moisture content between drying process and cooling process of cut tobacco could be ignored. Based on the variation factors of ambient temperature and humidity of the primary processing, the reasonable optimization design of the technical standard of the primary processing could effectively improve the stability of processing quality, which would have important practical significance in improving the stability of cigarette processing quality and product quality.
