The so-called "water jet" uses a high-pressure pump to pressurize the sealed water and sprays it through the extremely fine nozzle of a nozzle made of high-grade carbide, sapphire, diamond, etc. to cut the material. To do this, there is a relatively high demand for water, pipes, and spouts. Such as pipes, water jets use high-pressure tools to pressurize water and shoot out. It must have extremely high pressure to cut hard cutting materials, so pipes must be able to withstand extremely high pressure, which is far greater than 700 trillion Pa, because the thin steel plate (the material to be cut) itself can withstand a pressure of 700 MPa....

The rapid development of science and technology has made the machinery industry highly affirmed in the hearts of users, but during the development of fruit juice beverage production lines in my country, many obstacles have been encountered. Some beverage manufacturers in my country have to spend a lot of money to introduce some complete sets of juice beverage production lines with advanced technology and high production efficiency from abroad for technological transformation, resulting in a large part of the domestic market share being occupied by foreign brands. The development space of fruit juice beverage production line in my country is still broad, and the technical level of fruit juice beverage production line needs to be urgently developed....

With the improvement of people's living standards, consumers' pursuit of pure natural ingredients has become a trend, and food sterilization technology has also changed from traditional heat sterilization to cold sterilization. The application of HPP cold sterilization technology in the food industry is relatively mature, and it has been successfully applied in many fields such as fruit and vegetable juice, seafood, dairy products, meat products, and baby food....

Polysaccharides are polysaccharide macromolecular carbohydrates composed of at least 10 monosaccharides with sugar chains bound by glycosidic bonds. Polysaccharides composed of the same monosaccharide are called homopolysaccharides, such as starch, cellulose and glycogen; polysaccharides composed of different monosaccharides are called heteropolysaccharides, such as gum arabic, which is composed of pentose and galactose. Polysaccharide is not a pure chemical substance, but a mixture of substances with different degrees of polymerization. Polysaccharides are generally insoluble in water, have no sweet taste, cannot form crystals, and have no reducibility and mutarotation. Polysaccharides are also glycosides, so they can be hydrolyzed. During the hydrolysis process, a series of intermediate products are often produced, and finally monosaccharides are completely hydrolyzed. One of the most beneficial aspects of polysaccharides for pharmaceutical use is that they are biocompatible and biodegradable, and can be broken down naturally by the body, while also possessing many properties that make their hydrophilic structure more likely to target tumors , and its hydrophobic group provides a good carrier for insoluble drugs. Polysaccharides can also be used to form conjugate vaccines. However, the starting molecular weight of most polysaccharides is too large to take advantage of these great drug carrier properties....
