Clean laminar flow cover cleaning method
1. Check if the laminar flow cover is clean. If there is dust, remove the dust first. Shanghai Sujing Industrial Co., Ltd.
Organic mung bean starch is a kind of powder formed by the precipitation of mung bean after soaking and grinding with water. Our organic mung bean starch follows the traditional processing ideas and combines modern industrial technology to achieve a more efficient, safer, and more hygienic processing level. The characteristics of mung bean starch are sufficient stickiness, low water absorption, white and shiny color.
Mung bean (Vigna radiata) is a plant in the legume family. Mung beans are mainly grown in India, China, and Southeast Asia. The Chinese have grown mung beans for nearly 2,000 years. They are ubiquitous in China, and there are many types, and numbers. Mung beans are also grown in other countries/regions in South Asia, North America, Brazil, and Europe. The main provinces for mung bean cultivation in China are Anhui, Henan, Hebei, Hubei, Liaoning, Shanxi, Shaanxi, and Sichuan.
The nutritional value of mung bean starch is very high, and its uses are also very wide. For example, mung bean starch has antibacterial, antibacterial, hypolipidemic, antitumor, and detoxification effects.
Mung bean starch contains a considerable amount of oligosaccharides (pentosan, galactan, etc.). These oligosaccharides are difficult to be digested and absorbed because the human gastrointestinal tract does not have a corresponding hydrolase system, so mung bean starch provides a lower energy value than other grains and has an adjuvant therapy effect for obese and diabetic patients.

2. Use a disinfectant to scrub the front and back of the laminar flow hood before using the laminar flow hood.
3. Adjust the fan voltage adjustment knob to “zero†position to check whether the fuses are intact.
4. Press the main switch of the power supply, gradually rotate the adjustment knob, increase the voltage, and use the wind speed to measure the straight laminar wind speed after the laminar flow hood starts to supply air. Gradually increase the voltage, and the straight laminar wind speed is above 0.35m/s.
5. After the end, the voltage adjustment knob should be adjusted back to the “zero†position, and then the power switch should be turned off.
6. The mask of the laminar flow hood should be cleaned once a week with water for injection and then scrubbed with 35% alcohol.
7. When the air volume and wind pressure cannot make the wind speed>0.2m/s, the high efficiency filter should be replaced.
8. When replacing the high-efficiency filter, open the laminar flow mask cover plate, loosen the fixing screw inspection, replace it, and press it tightly to reinstall the upper cover plate.
