Cold air guide channel of tunnel type mesh belt instant freezer

Abstract

The invention discloses a cold air guide channel of a tunnel type mesh belt instant freezer. The cold air guide channel is used for conveying cold air discharged by each air cooling fan to a mesh belt, and consists of an air damper system installed in a heat preservation chamber body, wherein the air damper system comprises two side baffle plates, air dampers and an air guide plate; the air guide plates are transversely paved in the heat preservation chamber body; the two side baffle plates are respectively connected with two sides of the air guide plate; the air dampers are respectively an arc-shaped air damper; each air cooling fan is provided with one arc-shaped air damper; the arc-shaped indent surface of each of the arc-shaped air dampers is arranged in a way of being opposite to the air outlet of the corresponding air cooling fan; the end faces, located on the upper side, of the arc-shaped air dampers respectively contact with the top of the heat preservation chamber body; the end faces, located on the lower side, of the arc-shaped air dampers are supported on the air guide plate through a support, or are respectively connected with the baffle plates on two sides. Therefore, by the adoption of the cold air guide channel, the turbulence and the mutual interference of cold air circulation are reduced; the recycling circulation of cold air is improved; therefore, the freezing effect of the instant freezer is further improved.

Description

technical field [0001] The invention relates to a cold air guiding channel of a tunnel type mesh belt quick-freezing machine. Background technique [0002] The windshield system of the existing mesh belt quick-freezing machine is composed of side baffles, windshields, and wind deflectors. There is a right-angle bend between the windshield and the heat preservation storage body, and the cold wind will be lost here; The airflow between the group evaporators will also interfere with each other, affecting the cooling effect. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a cold air guide channel for a tunnel-type mesh belt quick-freezer, which adds arc-shaped windshields to the windshield system to reduce the turbulence and mutual interference of the cold air flow, and improve The circulation of cold air further improves the cooling effect of the quick freezer. [0004] For realizing above technical purpose, the...
