Abstract
The utility model relates to a fixed de-airing fresh-keeping apparatus with a gas regulation, which is composed of a fresh-keeping box body, a vacuum pump, a refrigerating machine, a water vapour condenser, a refrigeration vapour condenser, a water condensate receiver and an electric control box. The fresh-keeping box body is additionally provided with an oxygen inlet, a nitrogen inlet and a carbon dioxide inlet. The entered dosage of the oxygen, the nitrogen and the carbon dioxide can be adjusted according to different frozen foods. Thus the food can be frozen as well as being adjusted by the three gases, and thus the colour, the perfume, the taste and the appearance of the frozen foods can be ensured. The utility model is a de-airing fresh-keeping apparatus of the latest generation.
Description
The utility model relates to vacuum controlled atmosphere device, particularly fixed vacuum controlled atmosphere device.
As everyone knows, preservation technique to vegetables, fruit, aquatic products, meat is that employing is freezing at present, vacuum refrigeration and be coated with, soak anticorrisive agent, though some effects are arranged, but, must reach the requirement that the preservation technique that keeps original color and profile thereof could satisfy the numerous common people along with people more and more pursue the trend that the high health-care fresh-preservation of pure natural is lived.Though above-mentioned three kinds of traditional preservation techniques can not meet the demands.
The purpose of this utility model is to provide a kind of field, workshop of being applicable to vegetables, fruit, aquatic products, meat slaughterhouse to be carried out the device of vacuum controlled atmosphere, its advantage is to have overcome the heating and the corruption that can not solve the field for a long time to cause the bacterium ramp, particularly the field gather in the storage pile up and haulage time in the food problem of rotting, can keep original color and profile thereby make by fresh-keeping foodstuff.
Embodiment of the present utility model is as follows: it is by fresh-keeping casing, vavuum pump, refrigerator, water vapor condenser, freezing vapour cooler, water-cooled lime set receiver, electric cabinet seven big parts are formed, wherein said fresh-keeping casing is to be in rightmost, be provided with the freezing liquid pipe below its hollow, top is equipped with thermometer, diaphragm-type pressure gauge, the electric connection pressure vacuum ga(u)ge, vent valve, oxygen, nitrogen, the carbon dioxide valve, and the left end of water vapor condenser links to each other with fresh-keeping casing by big vacuum butterfly valve, bottom righthand side then links to each other with vavuum pump by little vacuum butterfly valve, and an end of refrigerator has connecting pipe to link to each other with freezing vapour cooler.The other end enters the bottom of fresh-keeping casing by gas-liquid separator, the gas that comes out from gas-liquid separator then enters the inlet of big vacuum butterfly valve by evaporating pressure regulating valve, pressure-regulating valve is arranged on the electric cabinet, high-pressure manometer and low pressure gauge, dial plate is provided with three thermometers, and the condensate liquid receiver is the bottom at water vapor condenser.
Following preference is described in detail the utility model in conjunction with the accompanying drawings:
Fig. 1 is each parts assembling front elevation of the utility model vacuum controlled atmosphere device.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the right view of Fig. 1.
From Fig. 1,2 and 3 as can be seen, when after being frozen food and putting into fresh-keeping casing, chamber door (1) is closed, start vavuum pump (12), refrigerator (19) is opened freezing gas, the running water terminal valve of cooler (15), the running water terminal valve of water vapor condenser (8) makes the inside tubulation of running water in this two condenser (8,15), and freezing G﹠W is carried out condensation.The gas that freezing liquid in the refrigerator (19) is told by gas-liquid separator (20) enters evaporator pressure regulator (21), and liquid then enters the cryovial in the antistaling box (22), will be frozen food and carry out freezing.Freezing liquid absorption simultaneously is frozen the thing heat and itself is vaporized, vaporizer enters freezing gas cooler (15) and returns refrigerator (19) again, after vavuum pump (12) starts, the surperficial moisture content major part that is frozen food is taken away, enter between the tubulation of water vapor condenser (8) by big vacuum butterfly valve (7), then be that logical running water carries out condensation in the tubulation, the water-cooled lime set bleeds off by water-cooled lime set groove (9).The steam that is not condensed enters vavuum pump (12) by little vacuum butterfly valve (11).
Oxygen intake valve (6), nitrogen intake valve (23) are arranged on the fresh-keeping casing (22), carbon dioxide valve (24) is according to different foods, suitably regulate its inlet to guarantee to restrain to greatest extent the breathing that is frozen food, suffocated and be unlikely, thereby reached color and the profile that keeps food to greatest extent.
As for the vent valve (3) on the fresh-keeping casing (22) be when in the fresh-keeping casing (22) because oxygenation or carbon dioxide or the too much pressure of nitrogen during greater than atmospheric pressure, usefulness as venting, film pressure vacuum ga(u)ge (4) and electric connection pressure vacuum ga(u)ge (5) are the pressure condition of observing in the fresh-keeping casing (22), and pressure-regulating valve (13) (18) high-pressure manometer (14) on the electric cabinet (10), low pressure gauge (16) are the usefulness as regulation and control pressure and indicated pressure.Filter (17) is to filter the usefulness that enters running water in water vapor condenser (8) tubulation.Three thermometers (25) and the thermometer (2) on the antistaling box that electric cabinet (10) is gone up dial plate are to be used to refer to be frozen the thing surface in the antistaling box (22) and to be frozen temperature conditions between the thing arrangement.
Advantage of the present utility model is as follows:
1. freeze preservation is effective, can keep being frozen color and the profile of thing.
2. equipment is simple, and each parts connects compact.
3. control easy to be stable.
