Abstract
The utility model discloses a kind of dismantled and assembled differential pressure precooling device, and provide one can realize fast, equably reduce the fruits and vegetables place of production heat, the device that differential pressure precooling device takes up space can be reduced again.Comprise blower fan and by front ancient piece of jade, round, flat and with a hole in its centre face, left wall, upper wall surface, right wall and rear surface respectively by the dismantled and assembled plenum chamber formed that links into an integrated entity of hinge, left wall and right wall are respectively arranged with air vent, and the porosity on left wall and right wall is 30-45%; Front face is provided with air port, and air port is connected with the air inlet of blower fan by hose connector.More adjacent pores footpath is less from the distance of blower fan for the aperture of air vent, and overhead higher aperture is larger.Dismantled and assembled differential pressure precooling device of the present utility model can be assembled at the scene, decreases the size of differential pressure precooling device plenum chamber, and can realize the flow field uniformity in pile, ensures that fruits and vegetables place of production heat is got rid of effectively.Improve the service efficiency of freezer, pre-cold efficiency is high.
Description
Technical field
The utility model relates to fruit vegetables storing technical field, particularly relates to a kind ofly can reducing the dismantled and assembled differential pressure precooling device taken up room.
Background technology
In preserving fruit and vegetable utilizing process, because huge after fruit and vegetable picking adopts the storage period that after heat can reduce fruits and vegetables, therefore need in short-term, fruits and vegetables to be lowered the temperature rapidly.
Fruits and vegetables are lowered the temperature rapidly, has now multiple method, as vacuum pre-cooling, the pre-cold-peace differential pressure precooling of frozen water.For vacuum pre-cooling, the heavy and selling at exorbitant prices of equipment, frozen water precooling then easily produces cross pollution, and therefore at source applying more is differential pressure precooling.
The patent No. be ZL201320864825 patent document discloses a kind of differential pressure precooling machine, it includes a plenum chamber, rectangular, is provided with supporting network on the top of plenum chamber, be provided with bracing frame in the two side ends of plenum chamber, be provided with at least one horizontal escape pipe at a side of plenum chamber; The patent No. be ZL201320363829 patent document discloses a kind of fruits and vegetables differential pressure precooling device, the blower fan comprising plenum chamber and be connected with plenum chamber, described plenum chamber bottom surface is provided with at least four rolling, is convenient to the movement of this pre-cooler; Patent No. ZL98202042 patent document discloses a kind of fruit and vegetable differential pressure precooling device, is made up of blower fan and plenum chamber.In current differential pressure precooling device, because plenum chamber is generally the equipment of fixed size, occupy larger space, affect the utilization rate of whole freezer, and air current composition requirement during pile when not considering fruits and vegetables differential pressure precooling, make precooling effect uneven.
Utility model content
The purpose of this utility model is the technological deficiency for existing in prior art, and provide one can realize fast, equably reduce the fruits and vegetables place of production heat, the dismantled and assembled differential pressure precooling device that differential pressure precooling device takes up space can be reduced again.
The technical scheme adopted for realizing the purpose of this utility model is:
A kind of dismantled and assembled differential pressure precooling device, comprise blower fan and by front ancient piece of jade, round, flat and with a hole in its centre face, left wall, upper wall surface, right wall and rear surface respectively by the dismantled and assembled plenum chamber formed that links into an integrated entity of hinge, described left wall and right wall are respectively arranged with air vent, and the porosity on described left wall and right wall is 30-45%; Described front face is provided with air port, and described air port is connected by the air inlet of hose connector with described blower fan.
More adjacent pores footpath is less from the distance of described blower fan for the aperture of described air vent, and overhead higher aperture is larger.
Described blower fan is centrifugal blower.
Compared with prior art, the beneficial effects of the utility model are:
1, in dismantled and assembled differential pressure precooling device of the present utility model, be connected through the hinge between each wall of composition plenum chamber integral, can assembling needed according to use or pull down, save and take up room, improve the service efficiency of freezer.
2, in dismantled and assembled differential pressure precooling device of the present utility model, more adjacent pores footpath is less from the distance of blower fan for the aperture of air vent, overhead higher aperture is larger, thus make the resistance of air-flow close, even flow field, ensure precooling effect evenly, be conducive to fast, reduce fruits and vegetables place of production heat uniformly, pre-cold efficiency is high.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The schematic diagram of the dismantled and assembled differential pressure precooling device of the utility model as shown in Figure 1, comprise blower fan 2 and by front ancient piece of jade, round, flat and with a hole in its centre face 1, left wall 5, upper wall surface 7, right wall 8 and rear surface 9 respectively by the dismantled and assembled plenum chamber formed that links into an integrated entity of hinge 10, described left wall 5 and right wall 8 are respectively arranged with air vent 6, and the porosity on described left wall 5 and right wall 8 is 30-45%.Described front face 1 is provided with air port 4, and described air port 4 is connected with the air inlet of described blower fan 2 by hose connector 3.Described blower fan 2 is preferably centrifugal blower.
In order to flow field evenly, more adjacent pores footpath is less from the distance of described blower fan 2 for the aperture of described air vent 6, and overhead higher aperture is larger.
When needs precooling, front face 1, left wall 5, upper wall surface 7, right wall 8, rear surface 9 are consisted of in freezer the plenum chamber of a cuboid hinge 10, utilize hose connector 3 that blower fan 2 and air port 4 are linked together.To the fruits and vegetables of precooling be needed along left wall 5 and right wall 8 pile, start blower fan 2, the cold air in freezer will pass through the air vent 6 of left wall 5 and right wall 8 along fruits and vegetables pile, enter into blower fan 2 be discharged in freezer again by air port 4 along hose connector 3.Cold air, when by fruits and vegetables pile, absorbs fruits and vegetables heat, thus the row torrid zone, the fruits and vegetables place of production is walked.
When not needing precooling, take chain connection apart, by front face 1, left wall 5, upper wall surface 7, right wall 8, rear surface 9 separately.
Dismantled and assembled differential pressure precooling device of the present utility model can be assembled at the scene, decreases the size of differential pressure precooling device plenum chamber, and can realize the flow field uniformity in pile, ensures that fruits and vegetables place of production heat is got rid of effectively.
The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
