Abstract

The invention relates to a method for using a pulsed electric field to kill insects and sterilize tobacco, which belongs to a plant preservation method, in particular to a method for using a high-voltage pulsed electric field to eliminate tobacco leaf fungus in tobacco. In the method, the tobacco leaves placed between the electrodes are acted on by low-frequency impact pulses with a pulse amplitude of 10-15Kv / cm for a certain period of time to kill insects and bacteria. One-way positive pulse or one-way negative pulse, or two-way pulse can be used. Through experiments, the invention can eliminate insects and fungi on the tobacco leaves in a short period of time. The invention has no pollution and secondary pollution, strong sterilizing power, low power consumption, safety and reliability, and is easy to use in industrialized production.

Description

Technical field [0001] The invention belongs to a method for preserving tobacco leaves, in particular to a method for using a high-voltage pulsed electric field to eliminate tobacco leaf fungus. Background technique [0002] During the aging process of tobacco, especially the natural aging time is about 3-5 years. Due to the temperature and humidity adapting to the reproduction of bacteria and fungi, tobacco germs multiply, and the tobacco leaves must be turned over every year to remove the moldy and deteriorated tobacco leaves. Tobacco leaf loss due to liquefaction averages about one-third. In order to reduce losses, chemical agents are generally used to kill and sterilize insects. For example, aluminum phosphide is used to fumigate and kill insects. The disadvantage of this method is the pollution caused by chemical agents, which is prone to operator poisoning, and inevitably causes more harm to smokers. In addition, the safety factor of aluminum ph...
