Description

Technical Field

[0001] The invention relates to the technical field of sugarcane detoxification, in particular to a device for detoxifying sugarcane pathogens using microwaves. Background Art

[0002] Sugarcane virus-free technology is mainly to deal with the repeated infection and accumulation of multiple pathogens caused by asexual seed planting of sugarcane for many years, which can not be controlled by chemical drugs, such as smut and shoot rot. These diseases have a great impact on sugarcane yield and may lead to a 10% to 50% reduction in yield. Therefore, it is particularly important to treat sugarcane mother plants and cultivate and apply virus-free seedlings. At present, the most commonly used sugarcane virus-free technology is hydrothermal treatment technology, which is an effective sugarcane virus-free technology. Sugarcane is placed in heated water with different heating time and temperature, which can be applied to different sugarcane virus-free. For example, a good virus-free effect can be obtained after heating at 49°C for 55 minutes. This method has little impact on sugarcane and a short processing time. It is currently a more commonly used technology; but the disadvantages are that the operation is complicated and energy-consuming, and the growth and quality of sugarcane are easily affected by the unstable heat treatment temperature, and all viruses cannot be completely eliminated.

[0003] The similarities between microwave and hydrothermal treatment lie in the thermal effect of temperature increase, and the difference lies in the non-thermal effect of microwave. Some researchers have conducted "microwave energy" sterilization tests on a variety of materials, thus confirming that microwaves have a certain non-thermal effect on the sterilization of food materials. Microwave detoxification is a purely physical method, which is safer than chemical drugs and preservatives, and the penetration of microwaves can inhibit latent infective bacteria inside the detoxified mother. However, in the conventional microwave detoxification process, if the continuous treatment time is too long, it is easy to change the organizational structure of the material and affect the quality, but terminating microwave detoxification cannot achieve the sterilization and detoxification level. Intermittent microwave treatment can reduce thermal damage caused by long-term radiation, such as protein denaturation, and reduce the negative impact on product appearance and taste, and has broad application prospects. Therefore, there is an urgent need in the field for a device for microwave detoxification of sugarcane mothers based on microwave detoxification technology, especially intermittent microwave detoxification technology.
