Industrialized promotion of ultrahigh-pressure sterilization equipment pressure is 100-600mpa ultrahigh-pressure container medium for water, part of the experimental type can also reach 1000mpa or higher, high-pressure cavity working medium is oil. Foreign research and development of ultrahigh-pressure food processing equipment earlier, the international well-known ultrahigh-pressure processing equipment manufacturing enterprises have the United States Avure and Spain NC Hyperbaric company. Able to produce laboratory research or production of HHP equipment companies are mainly the United States Avure Technologies, Elmhurst Research Company, the United Kingdom Stansted Company, Spain NC Hyperbaric Company, France Alstom Company, Japan Kobelco Company, Mitsubishi, Ishikawajima-harima, Stork Food&Dairy Systems B.V. in the Netherlands, ABB in Sweden and Uhde in Germany.
At the time, Sweden's ASEA was the first company to commercialize the isostatic pressure technology developed by the Battelle Memorial Institute (Columbus, Ohio). Twenty years later, ASEA became part of ABB, which focused on market development for isostatic and sheet metal forming presses. In 1999, ABB's High Pressure Division was acquired by Flow International of the USA. Flow led the expansion of high pressure technology in the food preservation market under the brand name Avure. In 2005, Avure Technologies, Inc. became a privately held independent company. Today, all four brands of presses are in operation at manufacturing facilities around the world.
Avure Technologies, Inc. in the U.S. produces presses up to 687L and NC Hyperbaric in Spain produces presses up to 600L. Pascal's Principle, formulated by Pascal in France in the 17th century, is usually stated as follows: Pressure on a confined liquid can be transmitted in all directions with constant magnitude. direction. Pascal's law is fluid dynamics, due to the fluidity of the liquid, closed containers of static fluid in a part of the pressure change, will be the size of the constant to all directions. Pascal first stated this law. The pressure is equal to the acting pressure divided by the area subjected to the force. According to Pascal's law, a certain amount of pressure applied to one piston in a hydraulic system must produce the same increment of pressure on the other piston. If the area of the second piston is 10 times the area of the first piston, the force acting on the second piston will increase to 10 times the area of the first piston, while the pressure on both pistons remains equal. This law was first formulated by the French mathematician, physicist and philosopher Blaise Pascal. This law has important applications in production technology, and the hydraulic press is an example of Pascal's principle. It has a variety of uses, such as hydraulic braking. Pascal also found that the pressure at any point in a stationary fluid is equal in all directions, i.e., the pressure at that point is equal in all planes passing through it. This fact is also known as Pascal's principle. It can be expressed by the formula: F1/S1=F2/S2
