Embodiment
Below in conjunction with accompanying drawing the present invention is done further description.
Shown in Fig. 1-2; A kind of 600Mpa screw mandrel lift UHV (ultra-high voltage) test unit comprises column 1, top cover transmission case 2, elevating screw 3, plunger type piston 4, steel ball guiding ring set 5, ultra-high pressure cylinder 6, it is characterized in that: also comprises: high pressure big piston 7, high pressure cylinder 8, linear guide pillar guide rail 9, guiding pressure head 10, combined frame self sealss 11, base 12.
Go up and down 3 to flexibly connect at the top of plunger type piston 4 and screw mandrel, arranged outside has linear guide pillar guide rail 9, is sheathed with steel ball guiding ring set 5 at the cylinder mouth of ultra-high pressure cylinder 6, and guiding UHV (ultra-high voltage) plunger type piston 3 is correct not to be had skew and get into ultra-high pressure cylinders.
During design, ultra-high pressure cylinder 6 adopts high-strength stainless steel material and 35-45 chrome molybdenum high-strength structure steel hot cover process, P
B=σ
s 
1nk (2- 
) plunger type piston 4 employing 17-4PH stainless steel materials.
During the work of 600Mpa screw mandrel lift UHV (ultra-high voltage) test unit; When plunger type piston 4 goes up and down 3 up-downs with screw mandrel; Guarantee vertical with ultra-high pressure cylinder 6 cylinder mouths by linear guide pillar guide rail 9; Make steel ball guiding ring set 5, guiding UHV (ultra-high voltage) plunger type piston 3 guarantees reliability and security that UHV (ultra-high voltage) plunger type piston uses.
600Mpa screw mandrel lift UHV (ultra-high voltage) test unit of the present invention institute application experiment is in extensive range, has to be applied in following field:
1, under inactivation of virus 200～400Mpa UHV (ultra-high voltage), can combine by the inner non-covalent bond of break virus membrane structure.Make between the film capsomere and disintegrate, space structure changes, Conformation Transition, and biologically active changes, thereby makes virus
Particle looses is infectious.But UHV (ultra-high voltage) does not destroy covalent bond, so the single subunit of antigen is not destroyed, and has kept immunogenicity constant.Can obtain do not have infectiousness and constant, the complete virion of immunogenicity with the method.
2, produce the traditional vaccine method of producing of vaccine, all adopt heating power and chemical treatment inactivation of viruses, there is very big drawback in these methods.For example inactivated influenza virus vaccine, traditional preparation process method are chemical method.It uses chemical reagent formalin-inactivated virus, is prone to make the virus surface particle impaired, influences the immunogenicity of vaccine.
3, handle the viral inactivation treatment that the existing at present several different methods of blood plasma is applied to blood product, as: pasteur's method, S/D method, serge blue luminescence method etc.But existing these methods all have certain defective.The S/D method is only effective to the virus that lipid envelope is arranged, and before transfusing blood to patient, must inactivator thoroughly be removed.
4, biological extraction can not only promote chemical reaction under the UHV (ultra-high voltage) state, can also change surface state, molecules align and the physical property of some materials.Superelevation pressure energy fast reaction speed in the biological extraction process shortens extraction time, improves product yield.
5, in the process, a lot of physiologically active ingredients are to responsive to temperature in bio-pharmaceuticals technology in bio-pharmaceuticals, and like aloe, balsam pear, spirulina, sea cucumber extract etc., in case temperature surpasses 60 ℃, its active component is promptly destroyed, and therefore is inappropriate for high-temperature sterilization; Adopt the UHV (ultra-high voltage) low temperature sterilization can guarantee fully that active component does not go to pot.
6, Chinese medicine produce the traditional handicraft of Chinese medicine be fried and the extraction.But a lot of crude drugs are to responsive to temperature, and 30% property of medicine is affected under the high temperature, adopt ultra high pressure treatment technology moment explosion vegetable cell, can intactly keep original composition, improve curative effect.
7, the sterilization of medicine equipment generally adopts high-pressure steam sterilization, and the pre-heating temperature elevation running time is long, adopts the superhigh pressure liquid sterilization, but real time operation, and the time is short, and is convenient.
8, the Treating Liquor of wine, yellow rice wine, grape wine etc. all need store a period of time and make the wine liquid sweet-smelling that becomes soft, and this often needs the time in several years.Use UHV (ultra-high voltage) and urge old technology, can shorten the storage time greatly, under the UHV (ultra-high voltage) effect; Water and alcohol quicken to form and form and system; Simultaneously also promote chemical reactions such as a series of oxidations, reduction, esterification and condensation, reduced sudden and violent peppery, towards nose and pungency, make taste soft, the sweet-smelling that becomes.For example yellow rice wine kept 20 minutes under ultra-high pressure condition, and fragrance increases 15-20%, was equivalent to store the effect of storage more than 16 months.
The comparison of ultra-high pressure sterilization technology and traditional sterilization technology:
1, superhigh pressure technique and traditional heat treated food comparison advantage are:
Ultra high pressure treatment can not make physical characteristicss such as food color change, and can not produce peculiar smell, after the ultra high pressure treatment; The gelatinization state and the heat treated of the sex change of protein and starch are different, and ultra high pressure treatment can keep original local flavor of food, are cold sterilization; Make food sterilizing reach even, instantaneous, efficient, and lower than the heating power consumption, for example; Japan Suntory Ltd. adopts container sterilization, and beer liquid can kill 99.99% Escherichia coli through HIGH PRESSURE TREATMENT.2, superhigh pressure technique and traditional chemical treatment food comparison advantage are: do not need in food, to add chemical substance; Overcome of the harmful effect of the product of material effect generation in chemical reagent and the microbial cell to the human body generation; Also avoided chemical reagent residual in the food negative effect, guaranteed edible safety human body.Chemical reagent uses frequent, can make thalline produce resistance, and bactericidal effect weakens, and ultra-high pressure sterilization is a disposable bactericidal, and is obvious to the thalline action effect.
3, the process characteristic of ultrahigh-pressure sterilization technology: the disinfection equipment of super high pressure food and general high-tension apparatus do not have the difference of essence, and just pressure medium is different, is generally water.Because the water capacity is prone to obtain, cost is low, the without explosion danger of comparing with gas, energy consumption is little.Usually pressure is 100～600MPa, and treatment process is to boost → three processes of pressurize → release, and charging usually, discharging are that discontinuous mode is produced.Most biologies promptly can be dead through the above pressurized treatments of 100MPa.
More than show and described ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the instructions just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain by appending claims and equivalent circle thereof, especially screw mandrel lifting structure form.
