Abstract

Abstract: The insecticidal effect of single vacuum, vacuum + nitrogen filling, vacuum + high temperature and low temperature rapid insecticidal methods of tobacco was studied. The technical measures of rapid insecticidal technology of tobacco were determined by comparing the changes of tobacco quality. The results showed that single vacuum insecticidal and vacuum + nitrogen filled insecticidal could not achieve the purpose of rapid insecticidal. Using vacuum degree ≤ 500 Pa, temperature 70 ℃, treatment duration 15 min or temperature -20 ℃ and treatment duration 2 h could achieve 100% killing effect on tobacco insects. Using vacuum moisture regain insecticidal technology, the insecticidal effect could be achieved when the main technical parameters were controlled at the vacuum degree ≤500 Pa, the temperature was 70 ℃ and the treatment time of tobacco leaf temperature was maintained at 15 min. After vacuum moisture regain insecticidal, vacuum cooling and dehumidification were used immediately for 30~60 min to quickly restore the water content and temperature of tobacco leaves, so as to avoid the adverse impact of high temperature and humidity on tobacco leaves; the insecticidal effect could be achieved by using low temperature and rapid insecticidal treatment. The temperature was -20 ℃, and the treatment time was 2 h. At the same time, in the process of cooling treatment, the intermittent negative pressure pumping method could quickly reduce the temperature of tobacco.

Key words: tobacco storage, pests, vacuum moisture regain insecticidal technology, low temperature and rapid insecticidal technology
