Problems solved by technology

[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 orifice plate is 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, which leads to a longer freezing time of the food and affects the freezing rate of the food and the operating efficiency of the quick-freezer.
At present, the structure of the orifice plate of the quick-freezing machine is basically a flat plate surface, and its structure is simple. Therefore, related research is rarely involved; changing the shape of the opening is a commonly used method at present, but changing the shape of the opening has no effect on the quick-freezing effect of the quick-freezing machine. Improved significantly

Abstract

The invention discloses a pore plate of an instant freezer. The pore plate comprises a first lateral-blowing pore plate board, a positive blowing pore plate board, a second lateral-blowing pore plate board and pore plate openings. The pore plate of the instant freezer is characterized in that the plane of the pore plate is an un-straight plane; and an included angle Theta is formed between the first lateral-blowing pore plate board and the positive blowing pore plate board. The pore plate can effectively strengthen convection heat exchange of the side surface of frozen food to reduce food freezing time, so that the single-direction impact problem of a conventional flat and straight pore plate is improved better, and therefore, a new idea is provided for improving freezing velocity of the instant freezer.

Description

Technical field [0001] The invention belongs to the technical field of quick-freezing foods, and relates to a quick-freezer orifice plate, in particular to an orifice plate 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-freezer, the orifice plate of the quick-freezer has been widely used in the food industry in recent years, but there is not much breakthrough in the research and design of the orifice plate itself. The air perforated plate is a straight surface. During the operation of the impact freezer, the cooled food is only impacted by cold air in a single direction, which causes the food freezing time to increase, and affects the freezing rate of the food and the operating efficiency of the freezer. At present, the structure of the orifice plate of the quick-freezer is basically a flat surface, and its structure is simple. Therefore, related research is...
