Toon buds are high-end foods that people like to eat. This kind of vegetable is very rich in nutritive value, contains many vitamins and amino acids that the human body needs. In order to improve the product quality of toona sinensis buds and solve the problem of easy defoliation and discoloration and go after the harvest of toona sinensis buds, the following methods can be used. 1. Basement is piled in the basement or in a cool and ventilated place. Sprinkle water on the ground first, and then stack the torreya on the mat. It is about 10 cm thick. Cover it with fresh grass or plastic film and keep it moist for 5 to 7 days. It can be used during budding seasons to disperse peaks and balance the supply market. Second, dipping storage method The size of the camphor buds of equal size, tied together into a small pot, standing in a basin or pool, add water, about 3 to 5 cm deep, soak 1 day and night, and then into the basket, can be saved 1 week. Third, the plastic bag sealing method uses 40 cm x 50 cm or 35 cm x 25 cm plastic bags, will be bundled into small fresh buds in the bag, sealed for 10 to 20 days. Midway can open bag air 1 time. Fourth, quick-freezing storage method with hot water flow scalding, and then placed in the temperature of minus 15 ~ 20 °C rapid freezing, the temperature maintained at minus 10 ~ 15 °C storage. When thawing, sprinkle with 5~10% citric acid to protect the color, flavor and prevent corruption. Fifth, frozen storage will be bundled into a small toads, the adsorption of garlic oil fluorspar or directly with 0.01% hydrogen purine preservatives sprayed, dried and then loaded in plastic bags (plastic bags 0.7 mm thick Above), tie the bag mouth, set the cold storage, the temperature is maintained between -1 ~ 0 °C. Every 10 to 15 days, you can open a bag and change the air once to keep the oxygen content in the bag no less than 2%, and the content of carbon dioxide does not exceed 5%. The shelf life can be 55 to 60 days. Large-scale intensive production must do a good job in cold storage construction.
ETR Oxygen Cylinder Filling System
By PSA principles, ETR PSA oxygen generators generate 93%±2% purity oxygen gas directly from compressed air. ETR oxygen cylinder
filling plant is consisted of Atlas Copco air compressor, Parker dryer and
filters, air buffer tank, ETR Psa Oxygen Generator, oxygen buffer tank,
oxygen receiver tank, diaphragm oxygen booster, filling station and control
cabinet.
Compressed air is purified through the air dryer and
filters to a certain level for main generator to work with. Air buffer is
incorporated for smooth supply of compressed air thus to reduce fluctuation of
compressed air source. The generator produces oxygen with PSA (pressure swing
adsorption) technology, which is a time proven oxygen generation method. Oxygen
of desired purity at 93%±2% is delivered to oxygen buffer tank for smooth supply
of product gas. Oxygen in buffer tank is maintained at 4bar pressure, then
reach to 150bar to filling cylinders with an oxygen booster.
