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 corrugated orifice plate for quick-freezing machines includes a first orifice plate arc surface 1, a second orifice plate arc surface 2, and orifice openings 3; the corrugated orifice plate for quick-freezing machines is characterized in that: the corrugated orifice plate surface is formed by the 1. The arc surface 2 of the second orifice plate, the radius of the arc surface is R, and the arc surface with an angle of 45° is circumscribed in turn, and the chord surfaces of all the arc surfaces are located on the same plane; the first orifice plate Orifice plate openings 3 with a radius of 5mm are evenly distributed on the arc surface 1 and the second orifice plate arc surface 2. The length of the arc surface between them is 35mm; along the groove dire...

Abstract

A corrugated pore plate for an instant freezer comprises a first pore plate cambered face, a second pore plate cambered face and pore plate open pores. The corrugated pore plate for the instant freezer is characterized in that the pore plate plane is a non-straight plane, and the corrugated pore plate is formed in a manner that cambered faces with the same radius are sequentially tangent externally. The corrugated pore plate can effectively increase the heat exchanging coefficient of the side face of food to be frozen, the freezing time of the food to be frozen is shortened, the single-direction impact problem of a traditional straight pore plate is solved relatively well, and a new thought is provided for a study on increasing the freezing rate of a blast instant freezer.

Description

technical field [0001] The invention belongs to the technical field of quick-frozen food, and relates to a corrugated orifice plate for a quick-freezer, in particular to an orifice structure for improving the freezing efficiency of the quick-freezer. 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 of the orif...
