Sowing and seed selection ginger seeds are removed from the storage pit 20 days before the appropriate ginger sowing time, and the soil on the ginger block is washed off with clean water, and the tiled rice is laid on a clean floor for 1 to 2 days. Drying can not only increase the temperature of the ginger block, speed up the germination speed, but also reduce the moisture content of the ginger block and prevent the emergence of mildew during the germination process. Some ginger seeds are sick, but before drying, the symptoms are not obvious. After drying, they often appear dry, shrunken, gray, and so on. Therefore, drying is also easy to eliminate diseased ginger seeds. Drying should be moderate, especially for younger ginger species, not exposure. If sunlight is strong at noon, mats can be used to shade. After drying, choose large, no-spotted, non-insect ginger seeds.
Seed soaking and soaking in sunny days, and soaking for 4-6 minutes with donin (77% copper sulphate) 600 times solution or 50% carbendazim 500 times solution mixed force 1000 times solution to kill germs. Soaking time should not be too long to prevent ginger from absorbing too much water and producing water. After soaking, ginger seeds are left to dry in the sun for one day.
Control germination temperature Before the ginger seeds are soaked in soil, spread a layer of soil about 10 cm thick on the soil to prevent the temperature at the bottom of the ginger pile from being too high. Then put the ginger seeds on the soil. The height of the ginger seeds should not exceed 50 cm so as to avoid a large gap between the upper and lower temperatures of the ginger heap. After the ginger seed is finished, it is covered with a 30-cm-thick wheat stub on top and sealed with a thin film. Ginger should be evenly inserted 5 to 6 thermometers, try to insert the thermometer into the middle and lower part of ginger heap. In the first 3 days, ginger pile average temperature should be controlled at 24 Â°C ~ 25 Â°C, not cold and hot; 3 days after germination, ginger itself can also be hot, can reduce the heating time, but the temperature should also be controlled at 24 Â°C ~ 25 Â°C; After 10 days, the temperature should be controlled between 20Â°C and 22Â°C; after 18 days, the ginger buds can grow to 2 cm in height and 1 cm in thickness.

Removable Oxygen Generator

Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%Â±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure.

With a cabinet for small capacity or container for big capacity, all the parts can be involved in, and removable with a vehicle.
