Oxygen Machine is one kind of product producing oxygen from air. There are small oxygen machine providing 3-10 liter per minute flow, mainly using at home. There are also big Industrial Oxygen Generator providing oxygen with flow rate up to 10000 Nm3/hr. From technology, there are pressure swing adsorption(PSA) , vacuum swing adsorptio (VSA)and cryogenic three types. The PSA type is for smaller flow rate within 300 Nm3/hr, from 300 to 3000 Nm3/hr, it is ok to use VSA technology. For bigger flow rate, normally use cryogenic Oxygen Plant.
No matter what technology, these oxygen machines all use oxygen in the air. All use Air Compressor to provide raw material, compressed air. Then the compressed air will be cleaned, dried for futher separation. After separation, the produced oxygen either directly goes to oxygen using point or they are compressed into high pressure such as 150 bars or 200 bars, then stored in cylinders and tanks.

The fruit hardness tester is a new kind of fruit hardness tester. The use of fruit hardness tester can firstly quantify the fruit hardness, and can more scientifically assess the maturity of the fruit, which helps to select the standard uniform fruit raw materials, and at the time of harvesting. The hardness of the fruit is measured by a fruit hardness meter, and the storage of the fruit at harvest can also be evaluated to guide the scientific storage of the fruit.
In the past, the traditional method for judging fruit maturity was to judge whether it was ripe by color change. Generally speaking, the fruit is green before it matures, and the green color diminishes when it matures. The background color and facial color gradually appear, so it can be based on the variety inherent to a certain extent. The degree of color appearance is used as a sign of harvesting. However, judging fruit ripeness by color is actually not very scientific, and it is especially difficult to quantify, so it is difficult to form a standard for assessing its maturity. In addition, the maturity of the fruit can be based on the content of chemical substances in the fruit. For example, the content of certain chemical substances such as starch, sugar, and acid in the berry and the ratio of sugar to acid in the fruit are related to the maturity. The time period for harvesting can be determined by measuring the content of these chemical substances, but this approach not only destroys the integrity of the fruit, but also it is very troublesome, and thus cannot be batch-oriented operation. The hardness of the fruit is different, and the hardness of the fruit will decrease with the increase of the fruit maturity. Using the fruit hardness meter to determine, the fruit ripeness can be identified by the quantitative determination results. Therefore, the fruit hardness tester will assess the maturity of the fruit in a more scientific and rational manner.
Fruit hardness tester more scientifically assesses fruit ripeness
The fruit trees are mature, although they can be visually observed for color changes or determined directly by hand, but they are all judged by human sensory feelings. They are actually not accurate and scientific, and modern industries such as canned food Fruit production, etc., have very high requirements for the maturity of fruit raw materials, so there will be some differences in this method, and it is not conducive to the formulation of canned fruit raw material standards, so the fruit hardness tester has begun to be applied.
