Abstract
The utility model discloses an absorption food vacuum cooling device and provides a device which absorbs water vapor evaporated due to vacuum by utilizing concentrated solution to achieve absorption vacuum cooling of food. The device comprises an airtight vacuum box, an absorption water catcher and a vacuum pump, wherein the absorption water catcher is formed by a box body and concentrated solution which is filled in the box body and absorbs water vapor; an outlet of the airtight vacuum box is connected with the box body of the absorption water catcher by a pipeline; an outlet on the box body of the absorption water catcher is connected with an inlet of the vacuum pump; gases in the airtight vacuum box enter the absorption water catcher and the concentrated solution in the absorption water catcher absorbs the water vapor from the gases; and dry gases enter the vacuum pump to be exhausted. The vacuum cooling device has the beneficial effects that absorption of the water vapor is achieved by adopting the absorption water catcher; the moisture absorption capacity of the concentrated solution in the absorption water catcher is stronger than the frosting capacity of the evaporator surface, so the food cooling speed is high; and the device has a simple structure and is low in cost.
Description
Technical field
The utility model relates to the vacuum cooled field, particularly relates to a kind of device that utilizes principle of absorption to realize the food vacuum cooling.
Background technology
Vacuum Cooling Technology on Food is to adopt vavuum pump to extract air in the airtight vacuum case, reduce the boiling point of water, allow and be placed on the interior food surface water evaporates of airtight vacuum case, the absorbing food product self heat is to reach the purpose of quick reduction food temperature, and this technology is widely used in the pre-refrigeration technique of food.When vacuum cooled, cause the damage of vavuum pump for preventing water evaporates, the normal water vessel that has refrigeration system that uses allows the moisture that is evaporated from food surface be condensed into frost at evaporator surface.In addition, the evaporation of moisture can strengthen gas volume under vacuum state, reduces vavuum pump efficient, and water vessel just can reduce cool time, improves cooling effectiveness.
The vacuum cooling unit that adopts refrigeration system to catch water is had relatively high expectations to refrigeration system, needs lower evaporating temperature usually, will reduce the Energy Efficiency Ratio of refrigeration system like this.In addition when serious as the evaporator surface frosting of water vessel, the operation that need defrost, vacuum cooling unit can not continuous operation.
The utility model content
The purpose of this utility model is at the technological deficiency that exists in the prior art, provides a kind of concentrated solution of utilizing to absorb owing to vacuum and vapor evaporated, realizes the absorption food vacuum cooling device of the absorption vacuum cooled of food.
For realizing that the technical scheme that the purpose of this utility model adopts is:
A kind of absorption food vacuum cooling device, comprise the airtight vacuum case, absorption water vessel and vavuum pump, described absorption water vessel is made up of casing and the concentrated solution that is filled in the absorption steam in the casing, the outlet of described airtight vacuum case is connected with the casing of described absorption water vessel by pipeline, outlet on the casing of described absorption water vessel is connected with the entrance of described vavuum pump, gas in the described airtight vacuum case enters described absorption water vessel, concentrated solution in the described absorption water vessel absorbs the steam in the gas, dry gas enters described vavuum pump, discharges through vavuum pump.
Between described airtight vacuum case and the described absorption water vessel casing outlet of connecting line be positioned at described absorption water vessel concentrated solution liquid level below.
Outlet on the described absorption water vessel casing is positioned at the top of described absorption water vessel casing.
Compared with prior art, the beneficial effects of the utility model are:
1, in the vacuum cooling unit of the present utility model, adopt absorption water vessel to realize the absorption of steam, the energy force rate evaporator surface frosting ability that the concentrated solution in the absorption water vessel absorbs moisture is strong, and the food cooling velocity is fast.
2, vacuum cooling unit of the present utility model adopts absorption water vessel to realize the absorption of steam, and simple in structure, cost is low.
3, the concentrated solution in the vacuum cooling unit of the present utility model is when saturated, can utilize solar energy, industrial exhaust heat equal energy source to realize that concentrated solution removes the process of moisture, is conducive to saves energy.
4, vacuum cooling unit of the present utility model can be realized the continuity work of vacuum cooled by adopting the above absorption water vessel of two covers, has improved production efficiency.And cost is well below the cost of two cover refrigeration systems.
Description of drawings
Figure 1 shows that the schematic diagram of the absorption food vacuum cooling device of the utility model.
Among the figure: 1. airtight vacuum case, 2. absorption water vessel, 3. vavuum pump.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the schematic diagram of the absorption food vacuum cooling device of the utility model, comprises airtight vacuum case 1, absorption water vessel 2 and vavuum pump 3.Described absorption water vessel 2 is made up of casing and the concentrated solution that is filled in the absorption steam in the casing.The outlet of described airtight vacuum case 1 is connected by the casing of pipeline with described absorption water vessel 2, outlet on the casing of described absorption water vessel 2 is connected with the entrance of described vavuum pump 3, gas in the described airtight vacuum case 1 enters described absorption water vessel 2, concentrated solution in the described absorption water vessel 2 absorbs the steam in the gas, dry gas enters described vavuum pump 3, discharges through vavuum pump 3.
The concentrated solution of described adsorbed water steam is lithium bromide, lithium chloride or lithium iodide solution, also can be other binary or multicomponent aqueous solution that can absorb moisture.
Between described airtight vacuum case 1 and described absorption water vessel 2 casings outlet of connecting line be positioned at described absorption water vessel concentrated solution liquid level below.
Outlet on described absorption water vessel 2 casings is positioned at the top of described absorption water vessel casing.
When the needs cooling food, food is placed in the described airtight vacuum case 1, opens described vavuum pump 3, at this moment because the reduction of the pressure in the vacuum cooling unit, the food surface moisture that is cooled absorbs rapidly be cooled food heat and explosive evaporation, reaches the purpose of cooling food.And vapor evaporated is absorbed by the concentrated solution that can absorb steam in the described absorption water vessel 2 through described absorption water vessel 2 time, and remaining dry air is discharged in the atmosphere through described vavuum pump 3.
When the concentrated solution that can absorb steam in the absorption water vessel 2 owing to absorbing that moisture is more to reduce concentration, can the water evaporates in the solution be fallen by ways such as heating.
The above only is preferred embodiment of the present utility model; should be noted that; for those skilled in the art; under the prerequisite that does not break away 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.
