Embodiment Construction

[0016] In order to make the operation process and creative features realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0017] The V-shaped orifice plate for the quick-freezing machine includes the first side blowing orifice plate surface 1, the second side blowing orifice plate surface 2, and the orifice opening 3; the V-shaped orifice plate structure of the quick-freezing machine is characterized in that: the first side blowing orifice plate The plate surface 1 and the second air blowing orifice plate surface 2 are hexahedral plate surfaces with a width of 80 mm, a thickness of 1 mm, and a length A; The included angle between them is θ; two rows of orifice holes 3 with a radius of 5mm and a hole spacing of 40mm are distributed on the first side blowing orifice plate surface 1 and the second side blowing orifice plate surface 2, and the two rows of orifice plate openings The ho...

Abstract

The invention discloses a V-shaped pore plate for an instant freezer. The V-shaped pore plate comprises first side air blowing pore plate surfaces, second side air blowing pore plate surfaces and pore plate holes, and is characterized in that the plane of the pore plate is a non-flat plane; an included angle theta exists between each of first side air blowing pore plate surfaces and each of second side air blowing pore plate surfaces. The V-shaped pore plate for the instant freezer can effectively increase the convection heat exchange coefficient of the side surface of quick-frozen food and shorten the freezing time of the food; and a new idea is supplied to research on increase of the freezing rate of the instant freezer.

Description

technical field [0001] The invention belongs to the field of quick-freezing of food, and relates to a V-shaped orifice plate for a quick-freezing machine, in particular to an orifice structure for improving the freezing efficiency of the quick-freezing machine. Background technique [0002] As a device to improve the uniformity of the cold air jet of the quick-freezing machine, the orifice plate of the quick-freezing machine has been widely used in the food industry in recent years, but there has not been much breakthrough in the research and design of the orifice plate itself. The air hole plate is generally a flat plate surface. During the operation of the impact type quick-freezer, the cooled food is only impacted by cold air in one direction, resulting in a low convective heat transfer coefficient on the side of the food, which increases the freezing time and affects the freezing rate of the food. The operating efficiency of the quick freezer. At present, the structure ...
