Abstract

The invention discloses a radiofrequency treatment method for sterilization and fresh keeping of cereal seeds, and the method includes the following steps: weighing the cereal seeds in a container, to be more specific, the cereal seeds are weighed into a cube container with a hole, wherein the hole diameter of the cube container is less than the diameter of the cereal seeds, and the cube container is made from a high temperature resistant plastic material; performing radiofrequency treatment on the cereal seeds, to be more specific, the radiofrequency treatment on the container filled with the cereal seeds is performed, the time of the radiofrequency treatment on the cereal seeds is controlled in 3-6min, after the cereal seeds reach the temperature of 60 to 70 DEG C, the cereal seeds are kept warm for 5-15min by hot air; and cooling to room temperature, to be more specific, the radiofrequency treated cereal seeds are cooled to room temperature for packaging and storage. By adopting the method, the cereal seeds can be better sterilized and kept fresh, and the vitality of the cereal seeds can be maintained while sterilization.

Description

technical field [0001] The invention relates to a sterilizing method for grain seeds, in particular to a radio frequency treatment method for sterilizing and keeping fresh the grain seeds, and belongs to the technical field of semi-solid forming of metal materials. Background technique [0002] my country is a large agricultural country, and the annual demand for crop seeds is about 2.4 billion kilograms, but the vigor of the seeds will decline to varying degrees during storage, and because the seeds will carry different types of fungi, especially molds, it is easy to cause Seeds are moldy, which seriously affects the activity and germination rate of seeds. At present, the technologies used for seed sterilization mainly include chemical sterilization and physical sterilization. Among them, the chemical bactericides used in the chemical sterilization method mainly include ozone and chlorine dioxide sterilization, etc., but this bactericidal method does not work inside the see...
