Embodiment Construction

[0009] 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.

[0010] A slit nozzle for a quick-freezing machine includes a V-shaped flow guide groove and a slit nozzle; Two strip-shaped plates arranged obliquely, the length direction of the strip-shaped plates is located in the horizontal direction, the cross section of the V-shaped diversion groove is rectangular, the longitudinal section in the width direction is an inverted trapezoid, and the two adjacent V-shaped diversion grooves The upper part is connected by a flat plate; the slit nozzle includes two strip plates arranged in parallel and vertically. The lower ends of the two strip plates of the groove are connected. The length of the slit nozzle is 1000-2000mm, the height of the V-shaped diversion groove 1 is 40-90mm, the opening angle of the V-shaped diversion gr...

Abstract

The invention relates to a slot nozzle for an instant freezer. The slot nozzle for the instant freezer comprises a plurality of V-shaped flow guide grooves which are uniformly arranged in parallel along the moving direction of a frozen product conveying plate belt and slot nozzle bodies communicated with the lower end of the V-shaped flow guide grooves; each V-shaped guide groove comprises two strip-shaped plates which are arranged in an inclined manner, the cross section of the V-shaped flow guide groove is in a rectangular shape, the longitudinal section of the V-shaped flow guide groove inthe width direction is in an inverted trapezoid shape, and the upper portions of every two adjacent V-shaped flow guide grooves are connected through a flat plate; each slot nozzle body comprises twostrip-shaped plates which are oppositely arranged in parallel, and the upper ends of the two strip-shaped plates of each slot nozzle body are connected with the lower ends of the two strip-shaped plates of the corresponding V-shaped flow guide groove respectively; the length of each slot nozzle is 1000-2000 mm, the height of each V-shaped flow guide groove (1) is 40-90 mm, and the opening angle of each V-shaped flow guide groove ranges from 0 degree to 30 degrees; and the height of each slot nozzle (2) is 2-8 mm, and the height of each slot nozzle (2) is 0-40 mm. According to the slot nozzlefor the instant freezer, the cooling rate of the frozen product can be effectively increased, and the quality of the frozen product is improved.

Description

technical field [0001] The invention belongs to the field of quick-freezing food machinery and relates to a slit nozzle for quick-freezing machines. Background technique [0002] The blast freezer is a common equipment in the field of quick-frozen food processing, and 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 problem of low freezing rate of frozen products in the freezing area. Contents of the invention [0003] The object of the p...
