Household Oxygen Generator is a type of machine for producing oxygen, its principle is to use air separation technology. First, the air is compressed at a high density and then the different condensation points of each component in the air are used to separate the gas and liquid at a certain temperature, and then rectify it to separate it into oxygen and nitrogen. In general, people are used to calling it an oxygen generator because it is mostly used to produce oxygen. Because oxygen and nitrogen are widely used, oxygen generators are also widely used in the national economy. Especially Homecare Oxygen Concentrator and Household Medical Devices for hospital and household.
The first countries in the world to produce oxygen generators were Germany and France. The German Linde Company made the world's 10th m3/s oxygen generator in 1903. Following Germany, the French Air Liquide Company also began to produce oxygen generators in 1910. Since 1903, the oxygen generator has a history of 100 years.

2, cellar temperature control off 1 into the cellar early, the outside temperature is high, in the absence of disease or disease is extremely light under the premise of open pit window, air eye, cooling and loose wet. When the cellar temperature is reduced to 15°C, the gas window and the air are closed, so that the cellar temperature is kept at 11°C~14°C, and the relative humidity is controlled at 80%~90%. 2After entering the cellar for 20 days, the management measures of insulation and antifreeze can be adopted: the amount of stored potatoes should be controlled at about 70% of the total volume of the pit; the thickened cellar wall should be kept more than 1 meter (except for pits), and the teffs should be covered with straw or straw. , Thickness of 20 cm or more; shallow cellar also covered with wheat straw or soil, to ensure the cellar temperature at 11 °C ~ 14 °C. 3 During the late period of storage, when it enters more spring rains, it is necessary to prevent the leakage of the cellar and waterlogging.
3, prevention and control to prevent potatoes rotten cellar, in addition to timely harvest to prevent the cold in the field, but also strictly selected to stay without lesions, insect injury, cracks and no broken pieces of potato into the pit.
Potato Cellar Technology
1, the old cellar disinfection Guan 1 potato harvest 10 days before, scrape the cellar walls of soil 3 cm, use new soil, and then brushed with lime mud; cellar bottom eradicate Chen soil 15 cm thick, remove the Chen soil, sprinkle a Lime. 2 According to the cellar volume, 50 grams of sulfur per cubic meter is used to smoke the cellar, and the cellar is sealed after ignition. After 1 to 2 days, the vent hole is opened. 3 Spray 1% sulfur copper solution or formaldehyde 50 times solution in the pit. 4200 times of phoxim is sprayed on the bottom of the cellar and cellar wall, and it can also be disinfected with 2% formalin.
