Embodiment 1

[0012] A method for killing tobacco mosaic virus, specifically comprising the steps of:

[0013] (1) Select fresh tobacco leaves with severe mosaic virus infection, place them in an oven, dry them at 60°C until the moisture content is 10%, and then crush them to 20 mesh. Raw materials such as tobacco stems and tobacco rods can be crushed to 0.5cm , get smoke powder;

[0014] (2) Put the above-mentioned smoke powder in the QB series supersonic ejection steam explosion machine, inject steam to make the pressure inside the steam explosion machine reach 0.52MPa, keep the pressure for a period of 90s and automatically discharge the material, and the mosaic virus in the smoke powder will be killed The mortality rate reached 90%.

Embodiment 2

[0016] A method for killing tobacco mosaic virus, specifically comprising the steps of:

[0017] (1) Select fresh tobacco leaves with severe mosaic virus infection, put them in an oven, dry them at 80°C until the moisture content is 15%, and then crush them to 40 mesh. Raw materials such as tobacco stems and tobacco rods can be crushed to 3cm, get smoke powder;

[0018] (2) Put the above-mentioned smoke powder in the QB series supersonic ejection steam explosion machine, inject steam to make the pressure inside the steam explosion machine reach 2.70MPa, keep the pressure for a period of 150s and automatically discharge the material, and the mosaic virus in the smoke powder will be killed The death rate reached 100%.

Abstract

The invention discloses a method for killing tobacco mosaic virus. The method particularly comprises the following steps: (1) selecting fresh tobacco leaves seriously infected with mosaic virus, arranging the selected tobacco leaves in an oven, drying at the temperature of 60 to 80 DEG C until the moisture content is 10% to 15% and then crushing the dried tobacco leaves to be 20 to 40 meshes, crushing tobacco stems, tobacco stalks and other materials to be 0.5 to 3cm to obtain tobacco powder; (2) arranging the tobacco powder in a QB series supersonic ejection type steam explosion machine, injecting steam so as to enable the pressure in the steam explosion machine to reach 0.52 to 2.70MPa, maintaining the pressure for 90 to 150s and then automatically discharging, wherein the mosaic virus killing rate of tobacco powder reaches 90% to 100%. The method provided by the invention has the advantages of easiness and convenience in operation, high efficiency and low energy consumption.

Description

technical field [0001] The invention relates to a method for killing tobacco mosaic virus. Background technique [0002] Tobacco mosaic virus, referred to as TMV, is a virus. Virus particles are rod-shaped, with a size of 300×18 (nm). Tobacco mosaic disease temperature is 90-93 ℃ for 10 minutes, the dilution limit is 1,000,000 times, and the in vitro protection period is 72-96 hours. It has pathogenicity for several years under sterile conditions and survives in dry disease tissues for more than 30 years. It is precisely because the virus has very strong vitality that tobacco waste is usually disposed of by incineration to avoid adverse effects of virus residues on tobacco planting in the coming year. Therefore, the resource utilization of tobacco waste cannot be widely and safely carried out for a long time. In order to avoid the environmental pollution caused by tobacco waste incineration, it is necessary to develop a safe and efficient way to kill mosaic virus in toba...
