Title:
JET NOZZLE STRUCTURE FOR IMPACT-TYPE FAST-FREEZER
Document Type and Number:
WIPO Patent Application WO/2019/104782
Kind Code:
A1
Abstract:
Disclosed is a jet nozzle structure for an impact-type fast-freezer, the jet nozzle structure comprising several V-shaped flow guide grooves (1) uniformly arranged in parallel in the movement direction of a frozen food conveyor plate belt (2), and slit nozzles (2) in communication with lower ends of the V-shaped flow guide grooves (1); the V-shaped flow guide groove (1) comprises two strip-shaped plates arranged obliquely relative to each other; the cross section of the V-shaped flow guide groove is rectangular, and the longitudinal section in the widthwise direction is an inverted trapezoid shape; upper parts of two adjacent V-shaped flow guide grooves (1) are connected via a flat plate; and the slit nozzle (2) comprises two strip-shaped plates parallel to each other, and upper ends of the two strip-shaped plates of the slit nozzle (2) are respectively connected to lower ends of the two strip-shaped plates of the V-shaped flow guide groove (1). The nozzle can effectively improve the uniformity in the process of lowering the temperature of frozen food, improve the relatively large differences in the rate of lowering the temperature of frozen food in a traditional structure at different positions in the process of food freezing, and increase the quality of frozen food.
