The number of human beings on the earth has increased dramatically. The demand for new residential commercial land has become increasingly large. The high-efficiency work of earth-moving machinery refers to the efficiency of construction work. The demand for engineering earth-moving machinery is enormous, including excavation, shoveling, Push or level machinery such as soil and sand. Widely used in construction, water conservancy construction, road construction, airport construction, mining, dock construction, farmland improvement and other projects.
For engines and hydraulic systems, oil cooling and water cooling systems are essential to ensure safe operation at high frequency and long-term harsh environments. Our professional design team can design customized solutions based on the engine and hydraulic requirements of different earthmoving machines. Ensure that the cooler is perfectly matched to the size of the engine, saving space and energy.

Determination of crude fiber in apples
Everyone knows that fruit is rich in vitamins, cellulose, and it contains a lot of water. Its nutritional value has not required us to emphasize it again. There is a good saying, "an apple keeps doctors away" eating an apple a day, and you don't need to go to a doctor. This shows how high the nutritional value of Apple is.
Crude fiber is a major component of plant cell walls, including cellulose, hemicellulose, lignin, and keratin. Crude fiber cannot be digested and absorbed by the human body, but even non-nutrients that cannot be digested can be of great help to the human body. It is closely related to human health and plays an important role in the prevention of certain diseases in the human body such as coronary heart disease, diabetes, colon cancer and constipation. At the same time, it also recognizes that the concept of "rough fiber" is no longer applicable. Change its discard to dietary fiber.
If you want to know the content of crude fiber in apples, we can measure it with a fiber tester and a CXC-06 fiber tester. CXC Series Crude Fiber Tester is a device that uses the commonly used acid-alkali digestion method to decoct a sample and perform weight measurement to obtain the crude fiber content of the sample. Following the national standard method GB 10469-89, the method for the determination of crude fibres of fruits and vegetables is basically similar, except that it integrates the steps in the national standard method into one instrument. Therefore, it is more simple and convenient than the determination of crude fibre in the national standard method. .
CXC-06 fiber measuring instrument can determine the content of crude fiber in various food, feed, grain, food and other agricultural and sideline products, and can measure six samples at a time, which improves the efficiency of measuring crude fiber. The crude fiber analyzer uses accurate concentrations of acids and bases to deconcoct the sample under specific conditions, and then removes soluble substances with ethanol. After burning at high temperatures, the amount of minerals is deducted. The crude fiber content is called crude fiber. It is not an exact chemical entity, but is a summary of the ingredients that are determined under generally recognized mandatory conditions, where cellulose is predominant, and a small amount of hemicellulose and lignin are present.
