Problems solved by technology

Traditional seed dryers use kerosene to heat the air. Using the principle of low relative humidity of the hot air, the humidity difference between the material and the hot air is used to take away the moisture of the material to achieve the purpose of drying, but this method greatly reduces the germination rate of the seeds.

Embodiment

[0016] First place the rice seeds indoors and spread them evenly; turn on the fan and dehumidifier at the same time, and set the indoor air humidity to 40%; keep observing the dryness of the rice seeds every day until it meets the standard after drying; it will meet the standard after drying After the rice seeds are dried and cooled to normal temperature, they are stored in the warehouse. The thickness of the rice seeds is 5-10 cm, which is conducive to the drying of the rice seeds and prevents them from being too thick. The water of the rice seeds at the bottom evaporates slowly and dehumidification The air humidity of the machine is set below 35%, which is beneficial to the temperature and humidity in the rice seed drying room, which is conducive to the evaporation of water from the rice seeds. There is also a desiccant in the room, and the rice seeds are dried by using the desiccant, which is safe and efficient. It is one of color-changing silica gel, calcium chloride or qui...

Abstract

The invention provides a paddy rice seed drying method and relates to a field of an agricultural technology. The paddy rice seed drying method comprises S1, placing paddy rice seeds in a room and evenly tiling the rice seeds, S2, simultaneously opening a fan and a dehumidifier and setting the indoor air humidity to 40%, S3, observing the degree of drying of the paddy rice seeds every day until the paddy rice seeds satisfy standards after drying, and S4, drying the paddy rice seeds satisfying the standards after drying, cooling the paddy rice seeds to the normal temperature and storing the rice seeds in a warehouse. The method keeps paddy rice seed dry, prolongs a paddy rice seed life, prevents heating and degeneration of the wet paddy rice seeds, inhibits microbial growth and is conducive to storage and transportation.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a method for drying rice seeds. Background technique [0002] Seeds need to be dried before storage to prevent moths, mildew and frost damage. The respiration intensity of seeds will increase with the increase of water content, and at the same time, a large amount of water and heat will be released, which will easily cause seeds to rot. Heat and mildew, so the seeds must be dried before they can be packaged, stored and transported. Traditional seed dryers use kerosene to heat the air, and use the principle of low relative humidity of the hot air to use the humidity difference between the material and the hot air to take away the moisture of the material to achieve the purpose of drying, but this method greatly reduces the germination rate of the seeds. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a rice seed...
