Description

High-pressure treatment apparatus

The utility model relates to high-pressure treatment apparatus, particularly relates to a kind of device that food is carried out the autoclaving processing.

The conventional method of food sterilizing is a heating.Though heating can reach sterilization effect, food has been caused adverse effects such as variable color, spoiled and nutritive loss.Therefore, development in recent years the pressure sterilizing of food method.Autoclaving is that food is packed in the high-pressure bottle, is pressurized to more than the 100MPa with liquid medium, makes food keep certain hour under this high pressure, thereby reaches the sterilization purpose.After HIGH PRESSURE TREATMENT, the bacterium in the food is killed, enzyme loses activity, and nutritions such as vitamin are unaffected, and fragrance and pigment all do not change yet.Thereby really realized not only sterilizing but also can keep natural flavour mountaineous purpose through the food of HIGH PRESSURE TREATMENT.Existing food high-pressure treatment apparatus has two classes.One class is indirect boost type, and promptly pressure medium is sent into high-pressure bottle by the road by pressure generator.Another kind of is the direct adding pressure type of pressure vessel inner carrier." food and machinery " (total 33 phases, P38～40 in 1991) have introduced a kind of indirect boost type high-pressure treatment apparatus.This device mainly is made up of pressure generator and high-pressure bottle two parts.The inside and outside double-layered cylinder structure that its high-pressure bottle is partly made for high-strength stainless steel.Inner/outer tube is that hot jacket is assembled.The lamination framework supporting that the upper and lower covers of cylindrical shell is manufactured with high-strength steel sheet.The working pressure of this device is about 400MPa.Because this device adopts high-strength stainless steel and double-decker, thereby the cost height, the manufacturing process complexity.In addition, the lamination supporting frame structure of this device cylindrical shell upper and lower covers is huge, and the internal volume of container is restricted, and complicated operation, and production efficiency is low.The permission working pressure of this device is also lower simultaneously, is difficult to satisfy the requirement of commercial sterilization effect.

The purpose of this utility model provide a kind of simple in structure, cost is lower, compressive resistance is high, vessel volume can be done greatlyyer, and is easy to operate, the pressure sterilizing of food treating apparatus that production efficiency is higher.

The purpose of this utility model is achieved in that booster system is made up of the reciprocating type extra high pressure charging machine of double plunger, combination valve and pressure duct etc.High-pressure bottle is the individual layer tubular construction, and the two ends of cylindrical shell are respectively with seal plug and potted component sealing.The front end of cylindrical shell connects with front plate 3,6 and support plate 5 with bolt, and forward end seal plug 15 is fixing by cushion block 2 and front plate 3.The rear end of cylindrical shell and rear plate 10,11 usefulness bolts combine as a whole, and back-end sealing plug 14 is fixing by rear plate 11.The high-pressure medium of being carried by booster system advances the cylindrical shell 8 that round enters high-pressure bottle on the seal plug 14 of back, thereby realizes the autoclaving processing to material in the container.During work, its axial load is finally born by cylindrical shell.

For improving vessel strength and service life and reducing container wall thickness, shell is made of high strength steel, and handles through self-reinforcing, and this moment, the wall ratio of cylindrical shell should be more than or equal to 1.2.

For guaranteeing sealing effectiveness, the potted component between cylindrical shell and seal plug combines with delta-ring 17, leather mat 18 and O type circle 19.Delta-ring is done with steel or copper.

For ease of packaged food pack into container and taking-up, be provided with the bin that is used to hold food in the cylindrical shell.The version of bin can be basket type, tubular or bathtub construction.

In the high-pressure bottle of the present utility model, its cylindrical shell is a single layer structure, and manufacture craft is simple, with low cost; The supporting structure of cylindrical shell termination is also greatly simplified, and has not only reduced cost, and has reduced the volume of whole device, makes the dischargeable capacity of container can do greatlyyer, thereby enhances productivity.Cylindrical shell adopts high strength steel to make, and handles through self-reinforcing, and the compressive resistance and the service life of container are greatly improved.In addition, its supporting structure also makes pack into cylindrical shell and take out more convenient of packaged food material.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a high-pressure bottle contour structures schematic diagram of the present utility model.

Fig. 2 is the structural representation of the utility model embodiment mesohigh container part.

Fig. 3 is the sealed structural representation of Fig. 2 middle cylinder body two ends.

Fig. 4 is A among Fig. 2-A cross-sectional view.

As shown in Figure 1, the cylindrical shell in the high-pressure bottle 8 is the individual layer cylindrical structure.The front end of cylindrical shell and front plate 3,6, support plate 5 usefulness numbers combine as a whole to bolt 4, nut 7.Front plate 6 is fixed on the base plate 1.Preceding seal plug 15 is fixing through front plate 3 and cushion block 2.Cylinder back-end is fixed with rear plate 10,11 bolt 9, nut 12 with several.Back seal plug 14 is fixing by rear plate 11.Sealed with potted component between front and back seal plug and cylindrical shell.Cylinder back-end is normally closed.Hole 13 is the path of high-pressure medium discrepancy cylindrical shell.Barrel front end often opens and closes, and front plate 3 has circular hole, is the material to be machined gateway.

In the embodiment of Fig. 2, the cylindrical shell of high-pressure bottle and supporting structure all with Fig. 1 in identical.Cylindrical shell 8 usefulness high strength steels are made.The front and back seal plug 15 of cylindrical shell and 14 and the sealing of cylinder inboard wall adopt the version of as shown in Figure 3 delta-ring 17, leather mat 18 and O type circle 19 combination sealings, be provided with baffle plate 20 in the end of seal plug.It is simple in structure, good sealing effect.In practicality,, also can save leather mat 18 according to operating position.Bin 16 is housed in the cylindrical shell 8, and as shown in Figure 4, the mode cross section of bin 16 is an annular.When food is carried out HIGH PRESSURE TREATMENT, at first unload lower cushion block 2 and preceding seal plug 15 and potted component, from the perforate of front plate 3, pull out bin 16, the packaged food of in bin, packing into.Then bin and food are pushed in the cylindrical shell, install potted component, seal plug and cushion block, import the high-pressure medium of self-boosting system from the hole 13 of cylinder back-end, food in the tube is carried out HIGH PRESSURE TREATMENT.After disposing, the booster system pressure release, high-pressure medium 13 is back to booster system from the hole.Open cylindrical shell by the aforementioned operation process then, take out the food behind autoclaving on the bin.For ease of holding food, bin 16 also can be made basket type or bathtub construction.

Among another embodiment of the present utility model, the supporting structure of high-pressure bottle, seal form, booster system etc. are all identical with embodiment among Fig. 2, but the cylindrical shell of high-pressure bottle is to handle through self-reinforcing again after making more than or equal to 1.2 high strength steel with wall ratio (ratio of promptly outer internal diameter).Like this, are greatly improved in the compressive resistance of high-pressure bottle cylindrical shell and service life.
