Description

Propelling supercharging device for ultrahigh-pressure food sterilization equipment

Technical Field

The utility model relates to an impel supercharging device that superhigh pressure food sterilization equipment used.

Background

The food ultra-high pressure sterilization is to apply 400-600 MPa of pressure or 100-1000 MPa of pressure to materials such as flexible package food and the like by using high-grade hydraulic oil in a closed ultra-high pressure container and using water as a medium. Thereby killing almost all bacteria, mold and yeast therein without causing nutritional component destruction and flavor change as in pasteurization. The mechanism of ultra-high pressure sterilization is to destroy the non-covalent bonds in the mycoprotein, so as to destroy the higher structure of the protein, thereby leading to protein coagulation and enzyme inactivation. The ultrahigh pressure can also cause the rupture of cell membranes of thalli, so that chemical components in the thalli generate outflow and other various cell injuries, the comprehensive action of the factors causes the application research of the high hydrostatic pressure technology for microbial death in food preservation to be provided by Bert Hite in 1899 at the earliest, the Bert Hite discovers that the high pressure of 450MPa can prolong the storage life of milk for the first time, and a great deal of research work is carried out by the Bert Hite and other colleagues, so that the sterilization effect of the high pressure on various foods and beverages is proved. Since then, research on HHP technology has been uninterrupted, and Bridgman has acquired the Nobel physical prize of 1946 because of the discovery of protein denaturation and coagulation under high hydrostatic pressure. But the research on HHP equipment, technology and theory is not broken through and developed until 1990, and the commercial application of the UHP technology in foods such as jam, fruit juice, salad dressing, seafood, jelly and the like is firstly realized by food companies in Ningming Zhi houses in the 90 s of the 20 th century. Later, universities, companies and research institutes in europe and north america have also successively accelerated the research of HHP technology. The food processed by the ultrahigh pressure of more than 100MPa can kill most or all microorganisms and passivate the activity of enzyme, thereby achieving the purpose of preserving the food.

Generally, the higher the pressure, the better the sterilization effect. However, the long pressing time under the same pressure does not necessarily improve the sterilization effect. Under the pressure of 400-600 MPa, bacteria, saccharomycetes and mycete can be killed, adverse changes caused by common high-temperature sterilization are avoided, the ultrahigh-pressure cold sterilization technology is high-pressure and normal-temperature sterilization, and after the food is treated by adopting the technology, the ultrahigh-pressure cold sterilization technology not only has high-efficiency sterilization performance, but also can well retain nutritional ingredients in the food, and the food has the advantages of good taste, natural color, high safety and long shelf life, which are not possessed by the traditional high-temperature thermal sterilization method. At present, the foreign ultrahigh pressure sterilization has a certain application in the production of fruits and vegetables, yoghourt, jam, dairy products, aquatic products, egg products and the like. Autoclaving was carried out with a pressure of approximately 6t weight per cm2 of meat. As a result, the taste was the same as the original one, and the color was better than the original one. The jam of strawberry, apple, kiwi fruit and the like is packaged in a flexible package and then sterilized under the conditions of 400-600 MPa and 10-30 min by Ningmingming House food company, the color and the flavor of the product are not changed, the original taste of the fruit is kept, and the VC retention rate is high.

Superhigh pressure sterilization relies on the hydraulic pump mainly to carry out the pressure boost as supercharging device, but we find in actual operation, and the booster pump mainly sets for the pressure of pressure boost through the manometer, but the mechanical structure of manometer is complicated, and stability is not high relatively, and when the manometer damaged, unable accurate control pressure easily leads to bearing food's pressure vessel spalling.

Therefore, the propelling supercharging device for the ultrahigh pressure food sterilization equipment is arranged between the hydraulic pump and the pressure vessel, is used for pressure transition and has a pressure limiting effect.
