Abstract

An elongated funnel-shaped jet flow nozzle structure comprises elongated conical diversion grooves, elongated jet flow nozzles and a conveying plate strip. The elongated funnel-shaped jet flow nozzlestructure is characterized in that thickness of the elongated conical diversion grooves (1), the elongated jet flow nozzles (2) and the conveying plate strip (3) is 1-5mm, each elongated conical diversion groove (1) is in the shape of a hollow inverted elongated oval frustum with an upper-end opening and a lower-end opening, the upper-end opening of each diversion groove is connected with an elongated oval open hole while the lower-end opening of the same is connected with an inlet of the corresponding nozzle, and each nozzle is in the shape of a hollow elongated oval cylinder. The elongated funnel-shaped jet flow nozzle structure can effectively improve heat exchange intensity of a freezing area, improve freezing efficiency of an instant freezer and effectively improve the defect that conventional nozzle structures cannot balance high freezing efficiency and heat exchange uniformity.

Description

technical field [0001] The invention belongs to the field of quick-frozen food machinery and relates to a slender funnel-shaped jet nozzle structure. Background technique [0002] The blast freezer is a common equipment in the field of quick-frozen food processing. Among them, the impact quick-freezer has become the object of close attention by quick-freezer manufacturers and scientific researchers because of its high convective heat transfer coefficient. The airflow in the static pressure box of the quick-freezer releases the high-speed airflow through the nozzle structure is the key to achieve the impact effect, and the impact effect depends to a large extent on the structure and size of the nozzle structure. The nozzle structure of the existing impact type quick-freezing machine is mostly a circular perforated plate structure, but this structure has the problems of low freezing rate of frozen products in the freezing area and low uniformity of the cooling process.
