The utlity model has following advantage: pressure tracking is regulated reliable and stable; Simple in structure, pressure control and regulation system that need not be complicated just can realize the variation of pressure following temperature and follow the tracks of variation; Fault rate is low, operation and easy to maintenance; The circulation of employing water, the water in the pot constantly flows, and heat distribution is more even.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with drawings and Examples the utility model is described in further detail: retort body 1, thermometer 2, flowmeter 3, heat-exchanger pump 4, circulation safety valve 5, circulating pressure table 6, indirect heat exchanger 7, water ring 8, air bleeding valve 9, sterilization pressure table 10, safety valve 11, water intaking valve 12, draining valve 13, intake valve 14, inlet valve 15, cooling water water intaking valve 16, initial steam pressure table 17, admission safety valve 18, condensation water valve 19, steam trap 20, cooling water dump valve 21.As shown in the figure, a kind of water circulation type foods packed in carton containers sterilizing unit, it is characterized in that: this device is by retort body 1, heat-exchanger pump 4, indirect heat exchanger 7 is formed, the delivery port at 1 end of retort body is connected with heat-exchanger pump 4 by pipe fitting, heat-exchanger pump 4 delivery outlets are connected with indirect heat exchanger 7 by pipe fitting, the outlet of indirect heat exchanger 7 is connected by the water ring 8 above pipe fitting and the retort body 1, form a hot water circulation loop, be connected to steam at indirect heat exchanger 7, the input interface 180 and the steam condensate (SC) of cooling water, cooling water output interface 190 forms above-mentioned hot water circulation loop heating, the pipeline of cooling; Connecting tube between retort body 1 and the heat-exchanger pump 4 is provided with thermometer 2, flowmeter 3, running water water intaking valve 12; On the connecting tube between heat-exchanger pump 4 and the indirect heat exchanger 7, be provided with circulation safety valve 5, circulating pressure table 6; Be provided with sterilization pressure table 10, air bleeding valve 9, safety valve 11 covering of retort body 1, steam, cooling water input interface are provided with steam valve 15, cooling water valve 16, initial steam pressure table 17, admission safety valve 18 on indirect heat exchanger 7, are provided with condensation water valve 19, steam trap 20, cooling water draining valve 21 at its steam cooling water equipped at outlet port.
The utility model retort 1, flowmeter 3, heat-exchanger pump 4, indirect heat exchanger 5 series connection, can form the hot water circulation loop of sealing by connecting pipe during sterilization, its principle is:
Before the sterilization, add water toward closed circuit, allow water logging not have foods packed in carton containers, and make water level rise to the position of water ring 8, close pot cover, start heat-exchanger pump 4, loop water begins circulation.
Temperature rise period: when the water of closed circuit by between when drawing the Steam Heating of heat exchanger, the air themperature in recirculated water and the loop rises, and along with the rising of temperature, aqueous vapor expands, circuit pressure also correspondingly increases automatically.
The sterilization holding stage: when reaching sterilization temperature, as long as control is temperature-resistant, the pressure of recirculated water also is constant.
Cool the stage: when sterilization finishes cooling, close steam, import cooling water, system is by the water quench of indirect heat exchanger, and water, air cooling in the loop are but shunk, and pressure also correspondingly reduces automatically.When temperature is reduced to the temperature of technological requirement, open air bleeding valve 9, pressure is reduced to normal pressure, open the sterilization pot cover and take out foods packed in carton containers, just can finish whole sterilization process.
The water inlet in loop is by water intaking valve 12 controls, and draining is by draining valve 13 controls.

Guarantee safety for preventing that superpressure from moving, be separately installed with circulation safety valve 5, pot safety valve 11 and admission safety valve 18 in the device.
The utility model comprises vertical retort (sterilization container that pot body cylindrical shell is erect) and horizontal sterilizer (sterilization container of pot body cylindrical shell accumbency).
Be not subjected to the influence of heat medium or cooling medium for the pressure that makes closed circuit, this device adopts indirect heat exchange modes such as plate heat interchanger, spiral heat exchanger or tubular heat exchanger, be the one side flow circuit water of metallic plate, mobile heat medium of another side or cooling medium.
The utility model can also be further perfect by following structure and operation:
(1) vertical retort, the place different with traditional retort are that water ring is not contained on the pot cover and is contained in pot body cylindrical shell top edge, to avoid the leakage of the movable water inlet of pot cover; The hole for water spraying of water ring is tilted to, and makes the water that enters retort spray to the air in pot cover zone, makes air heating in time or cooling.For horizontal pot, its structure and existing retort are basic identical.For conserving water, horizontal sterilizer need have hot water recovery unit, and when preventing that pot cover from opening, the water of horizontal pot is run away.
(2) correction of pressure divergence in the sterilization process under a certain heating-up temperature, when pot inner pressure is higher than the pressure of technological requirement, can be opened air bleeding valve, part incoagulable gas in the venting pot; When pot inner pressure is lower than technological requirement, open intake valve, add compressed air in right amount.Loop seals gets final product well.
(3) heat is delivered in the jar outside foods packed in carton containers needs the regular hour, the variation of foods packed in carton containers temperature inside and pressure is jar outer hysteresis to some extent all, retort has reached a certain pressure in other words, but also do not reach in the foods packed in carton containers, poor for reducing the foods packed in carton containers external and internal pressure that this hysteresis brings, intensification and cooling rate are too fast, are controlled in 15-20 minute just can address this problem.
