Flat-type efficient plate and strip instant freezer

Abstract

The invention relates to an F25D refrigerating machine, refrigeration equipment or system category in IPC (International Patent Classification) by searching, and in particular belongs to a flat-type efficient plate and strip instant freezer. The technical scheme is as follows: an evaporator (1) and a cold air room (2) are arranged in a library body (12); a centrifugal fan (3), an upper air blowing room (4), an upper nozzle (5) and a plate belt (7) are arranged below the evaporator (1) and the cold air room (2) in sequence; and the instant freezer is characterized in that the upper air blowing room (4) is connected with the evaporator (1) by an upper and lower air room ventilating duct (8), a lower air blowing room (9), a lower nozzle (10) and a return air room (11) in sequence. The instant freezer has the beneficial effect that the heat transfer area is increased manyfold because the upper and lower surfaces of a freezing object are jetted by cold airs at the same time, thus the freezing speed is quicker, the energy consumption is reduced, and the freezing quality of the freezing object is preferable.

Description

[0001] technical field [0002] After retrieval, the present invention relates to the F25B refrigerator, refrigeration equipment or system category on the International Patent Classification (IPC), and in particular belongs to a flat type high-efficiency strip quick-freezer. Background technique [0003] Some of the existing strip quick-freezers directly blow cold air on the frozen objects on the steel belt, and there is no cold air blown on the back of the strip, so only the upper side of the frozen objects is affected by the low-temperature cold air, and the cold air is not accelerated by the nozzle, and the wind speed is very high. low, resulting in long freezing time, high energy consumption, low production efficiency, and poor quality of frozen substances; some aluminum alloy flat evaporators are installed on the back of the strip, and the aluminum alloy flat evaporator requires close contact with the strip. This structure will cause The plate strip and the aluminum al...

[0003] Some of the existing strip quick-freezing machines directly blow cold air on the frozen objects on the steel belt, and there is no cold air blown on the back of the strip, so only the upper side of the frozen objects is affected by the low-temperature cold air, and the cold air is not accelerated by the nozzle, and the wind speed is very high. low, resulting in long freezing time, high energy consumption, low production efficiency, and poor quality of frozen substances; some aluminum alloy flat evaporators are installed on the back of the strip, and the aluminum alloy flat evaporator requires close contact with the strip. This structure will cause The plate strip and the aluminum alloy flat plate evaporator are severely worn and difficult to realize; in addition, some use non-moving fluid to spray the back of the plate strip, which complicates the structure, adds many auxiliary equipment, and may contaminate food , also not practical
