Description
Technical Field
The utility model relates to a seed treatment technical field, concretely relates to seed drying tube.
Background
The primary purpose of seed drying is to reduce free water in the seed and to increase the seed's storability so that seed vigor can be maintained for a longer period of time. The newly harvested seeds, particularly the seeds harvested in rainy days, are not easy to dry in the natural storage process, particularly in moist and humid areas, the water content of the seeds is high, the physiological effect of the seeds is vigorous, and the heat released by respiration is large, so that pathogenic bacteria or pests are easy to breed, and the planting value is lost quickly. Seeds are living organisms that breathe at all times, even when they are dry or dormant, but they do so despite their diminished intensity. In order to ensure safe storage of the seeds and to increase the longevity and viability of the seeds, the seeds must be dried. The seed drying speed depends on the ambient temperature, relative humidity and air flow rate. The higher the air temperature, the lower the relative humidity, the faster the flow rate, and the faster the seeds dry. In contrast, seeds dry slowly.
The seeds are a mass of gel and have the characteristics of adsorption and desorption to moisture. When the external water vapor pressure is less than the internal water vapor pressure of the seeds, the seeds are dehydrated and dried. Seed drying is generally divided into natural drying and non-natural drying. The former is susceptible to site and weather conditions; the latter includes mechanical aeration drying, infrared radiation drying, desiccant drying, microwave drying, conduction drying, freeze drying and the like. The drying agent drying method has the characteristics of safe and efficient drying, manual control of drying level, suitability for drying seeds with different quantities and sizes and the like. And the drying agent can be selected according to the industry standard blue gel indicator, allochroic silica gel and cobaltless allochroic silica gel (HG/T2765.4-2005), and the use cost is low.
The seed drying device is a seed drying container which utilizes the moisture absorption balance characteristic of seeds to moisture, continuously evaporates and reduces moisture in the seeds when the water vapor pressure in the environment is lower than the water vapor pressure in the seeds, does not influence the vitality of the seeds, enables the seeds to be dried for a long time, maintains stronger vitality, and has important significance for relevant work such as well-done safe seed storage. Aiming at a seed drying agent drying method, a seed drying device commonly used in a laboratory at present is a glass dryer. The novel multifunctional desk has the problems of heavy volume, easiness in damage, difficulty in moving, inconvenience in placement, difficulty in operation (opening a cover) and the like, and certain difficulty is caused for smooth development of related scientific research and teaching work. In order to obtain accurate scientific research results and facilitate teaching work, continuous innovation and improvement are needed to be carried out on a seed drying device and the like according to actual requirements in the seed drying process.
