Abstract
The invention provides a vacuum precooling fresh-keeping device. It is characterized in that besides an inclosed box and a refrigeration system, it also comprises a vacuum pumping system for controlling vacuum degree in the box. Ventilation holes are arranged around inner wall of the box. A suction tube of a vacuum pump of the vacuum pumping device is connected to an inner chamber of the box. Cooling speed is quick, temperature is uniform, and thermal insulation effect of the box is good.
Description
Technical field
The present invention relates to the combined unit of vacuum and refrigeration, is a kind of vacuum precooling device.
Background technology
As everyone knows, the food that the mankind depend on for existence, no matter be vegetable food or animal food, they all are carbohydrate, dewater especially in its composition, also difference includes fat, protein, carbohydrate, vitamin, mineral matter and enzyme etc.The difference of these component contents is determining the quality and the nutritive value of different food products.Simultaneously, we know that under the room temperature environment condition, the preservation of FF is a very big difficult problem, and standing time is of a specified duration excessively, and qualitative change or rotten takes place easily, and this causes great difficulty for links such as preservation or transportation.Rotten even the rotten main cause of FF is, because of all kinds of plants after gathering or fowl domestic animals by the soma after invading, its histocyte still has respiratory function, breathes to make that " life " is continued, that is keep fresh, but breathing can consume nutrient, distribute moisture content, and sends a lot of respiration heats, and it is many more to breathe fast more heating, add the original heat of FF, make that the temperature of placing food is more and more higher, food is " water outlet " more and more, and temperature also makes ethene produce in a large number.The condensation of moisture that distributes, adding high temperature is the suitable environment atmosphere of cultivating go mouldy bacterium and fungi, poisonous bacterium breeds in a large number, FF just goes mouldy very soon, rot. in Study on preservation technique, find, FF is difficult to permanent main cause of preserving, storage temperature can constantly raise voluntarily, humidity increasing and air pressure conditions help the growth of harmful bacteria, breeding, but in low pressure, under the cryogenic conditions, can kill or mould fungus inhibition, fungi existence, can suppress the plant or the histiocytic breathing of fowl carcass of collection, prevent dehydration, go mouldy. so collection class plant or fowl domestic animals are slaughtered the low pressure of body, the preservation by low temperature technology has obtained extensive studies and development, various vacuum freshness retainings, preservation by low temperature equipment or device are used widely, as vacuum packaging equipment, icebox, refrigerator, refrigerating box (cabinet) etc. make a general survey of existing preservation device, the mostly just independent utilization of vacuum technique or cryogenic technique, as refrigerating box (cabinet), consist predominantly of a sealable casing in its primary structure, one refrigeration compressor and one is arranged on the fan in the casing, refrigeration compressor is carried cold air by refrigeration condenser pipe and fan in casing, make the interior temperature of casing reach 2-5 degree centigrade.The refrigerating box (cabinet) of structure like this, its weak point mainly are to lack effective bactericidal action, so preservation is limited, particularly fresh-keeping foodstuff are taken out soon from case (cabinet), promptly will damage.
The purpose of this invention is to provide a kind of vacuum precooling freshness retaining device, make it both to have cryopreservation, reduce water evaporates, change the existence of bacterium class, breeding condition, suppress the in-house physiological metabolism effect of foodstuff storing, and, bactericidal action had again, harmful gas such as the interior ethene of favourable casing are discharged, and help advantage such as fast cooling, better insulation in the casing.
For achieving the above object, the present invention consists predominantly of a sealable casing, a refrigeration compressor and is arranged on the fan in the casing, simultaneously, the present invention also includes a vacuum extractor in order to vacuum in the control casing, be placed with the passage that communicates with chamber within the box body wall on the inwall around the casing, the exhaust tube of the vavuum pump of vacuum extractor inserts the box body wall inner chamber.
In addition, for prevent vacuumize with the low-temperature operation processing procedure in, the top layer phenomenon of losing water takes place in relevant article (particularly gathering the class fresh plant) in the case, and the present invention can be provided with damping device by suitable position in casing. and make and can make humidification (as spray or spraying) with low-temperature operation backsight feelings and handle vacuumizing.And to doing cleaning more completely in the casing, the present invention is provided with the draining dirt discharge groove on tank floor, and also is provided with a check valve in the bottom of draining dirt discharge groove for convenient.
The model machine made of the present invention as mentioned above, after measured and on probation, have following major advantage: cooling velocity is fast, temperature is even, cabinet insulation is effective, and stock do not dewater substantially, indeformable, particularly can reach fresh-keeping purpose of long period effectively, for example, it is generally acknowledged difficult leek, the sponge gourd of depositing, in common refrigerating box, deposited two days, promptly as seen promptly will be out of shape rotten after the taking-up, but leave a week in the preservation device of the present invention in, can see that still quality is still.

Fig. 2 partly cuts open schematic diagram for the forward of vacuum of the present invention, low temperature and control device.
The specific embodiment
Embodiments of the invention are as shown in drawings. below in conjunction with the accompanying drawing illustrated embodiment the present invention specified.
At first see by Fig. 1, Fig. 2, the present invention consists predominantly of a sealable casing 8, a refrigeration compressor 17 and is arranged on the fan 6 in the casing, casing 8 among the present invention, its tank wall is made of an inside and outside two layers of surface layer 1,5 and a middle heat-insulation layer 2, be provided with inner chamber 3 between heat-insulation layer 2 and endosexine 5, the suction tube 16 of vavuum pump 15 promptly patches in this inner chamber 3.See by Fig. 1, be placed with the passage 7 that communicates with chamber 4 within the box body wall on the inwall 5 around the casing 8, after starting vavuum pump 15, can be to vacuumize in the casing equably then, see that by Fig. 1 the present invention is provided with spraying (pouring) damping device 4 at the casing internal upper part by passage 7 and inner chamber 3; Be provided with draining dirt discharge groove 9 at the tank floor pars intermedia, be provided with 11 sealed doors among check valve 10. figure again in the bottom of draining dirt discharge groove 9 for the turnover reserve for casing 8.
Figure 2 shows that the schematic diagram of power of the present invention and control device.The present embodiment special secondary school is provided with a power box 12, and various gauge outfits 13,14 such as control circuit and temperature, humidity, vacuum are housed on the top of this power box, and vavuum pump 15 and refrigerant compression pump 17 are housed in the casing.Fresh-keeping casing 8 is arranged on the same base with power box 12, constitutes a monolithic construction.For adapting to various use occasions, also can be arranged on antistaling box casing 8 and power box 12 on the different bases, constitute split-type structural.
