The production site is located at the southern end of the Hengduan Mountains, with an elevation of about 2,000 meters and the coast of the Bohai Sea. Tea gardens surround the Bohai Sea, where the climate is unique, the situation is changing, the temperature is high at noon, the temperature is low, and there are many clouds. Snow-capped peaks in winter and spring flowers bloom in the mountains. The summer and autumn are full of clouds and humid air. The average annual temperature is 15 to 16°C, annual rainfall is 1000 to 1300 mm, and sandy yellow loam, PH 4.5 to 6.0. The tea tree grows.
The temperature is 100-300 meters above sea level, average annual temperature is 15 degrees Celsius, above 300 meters above sea level, and below 14 degrees Celsius. The average temperature in July is 28.2 degrees Celsius, the average temperature in January is 2.1 degrees Celsius, the temperature in spring and autumn is cool and mild, and the average temperatures in April and October are respectively It is 15.4°C and 16.7°C. The average annual frost-free period is 210-220 days, the average initial frost day is November 5th, the final frost day is March 29, the first day of stable adoption of 10°C is April 15, and it ends on November 4-9; ≥0 The accumulated temperature of °C is 5085-5500°C; the accumulated temperature of ≥10°C is 4384-4750°C.
The annual total solar radiation is 506.18 kJ/cm2, and the daily solar radiation during the daily average temperature ≥0°C is 369.69 kJ/cm2, accounting for 73% of the total annual radiation. The annual sunshine hours are 2000-2230 hours, the annual sunshine percentage is about 50%, and the light energy resources are relatively abundant.
The annual average rainfall of precipitation is between 1,200 and 1400 millimeters. According to statistics, the average annual rainfall in 25 years is 28.9% in spring, 41.1% in summer, 19.4% in autumn, and 10.6% in winter. The average annual precipitation days are 125.6 days, annual relative humidity is 80%, dryness is 0.8 or less, and it is a wet zone.
Soil soil types are more complex. Zhongshan District (inner mountain area) is mainly yellow-brown, ie, yellow-brown and yellow-brown. The parent materials are mostly granite, granite gneiss, and hornblende gneiss. The soil depth is more than 1.5 meters and the content of organic matter is high. Soil fertility and permeability are good, PH 4.8-5.5; outer hilly areas (outside mountainous areas) are dominated by yellow-brown soils derived from the parental system of soil-forming parent materials. Although the soil layer is thick, the cultivation layer is shallow. The texture is heavy, the bottom layer is often impervious to the viscous disc layer, and the fertility and permeability are poor, PH5-6.5; the second is the lesser part along the banks of the river and valleys, mostly alluvial soils, ie sandy loam (Ushatu), soil Deep layer, high fertility, good permeability, generally high-yielding tea park.
Containerized Oxygen Generator
Containerized Oxygen Generator
ETR can combine all parts of the oxygen generation system into a customized container, including air compressor, refrigerate air dryer, filters, buffer tanks and oxygen generator. Even the optional oxygen booster and cylinder filling station.
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%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure.
