Black and White Ultrasound Scanner "Black and White Ultrasound Scanner" is to emit ultrasonic waves, so that the ultrasonic waves encounter barriers to generate echoes, use the computer to collect these echoes, convert them into corresponding images and display them on the screen, and the images measured by the ultrasonic probe are black and white, so it is called " Black and White Ultrasound Scanner" is also the earliest diagnostic technology adopted by b-ultrasound.

1, tea sealed storage method. Store large quantities of green, red and green tea, use porcelain jars or ceramics, add 0.5 kg of hygroscopic agent such as charcoal (in a cloth bag), and use kraft paper to pack 0.15 to 0.5 kg of tea into a bag around the absorbent bag. Above, seal the mouth of the altar. Replacement of the moisture-absorbing bag once every 3 to 4 months. For storage of high-quality tea, blocky stone dust can be used as a moisture absorbent, and lime should be placed in a cloth bag to prevent direct contact with tea leaves. For the storage of tea or black tea, quicklime should not be used to prevent loss of aroma. Different types of tea are best stored separately to prevent mutual influence and odor. The absorbent capacity of silica gel is 1000 times that of lime, and it can be used repeatedly. That is, the silica gel after moisture absorption can continue to be used after sun exposure and baking, and it is an ideal moisture absorption agent for storing tea leaves.
2, tea low temperature storage method: the tea into the sealed iron, porcelain containers, and then set the plastic bag moisture, into the refrigerator, if the temperature is below 5 °C, can be stored for more than one year. It is best to store famous teas and flower teas in this way. Since the refrigerator is relatively humid, it is easy to savor the taste of various foods. Therefore, the container for placing the tea must be sealed well. In addition, teas for home use can be stored in tin cans with double lids and stored in a dry place without mixing with odorous items.
"Black and White Ultrasound Scanner" has the advantages of non-invasive, high sensitivity, low cost and convenient operation
Several storage methods of tea
Store tea leaves to maintain the inherent color and flavor of tea, so we must try to fully maintain the dry, to minimize the impact of external temperature and humidity, to avoid contact with objects with odor, but also to make tea without extrusion and impact to keep it Original shape, true color, and true taste. Here are some common tea storage methods:
