Title:
BEVELED SLOTTED NOZZLE FOR INSTANT FREEZER
Document Type and Number:
WIPO Patent Application WO/2019/104784
Kind Code:
A1
Abstract:
A beveled slotted nozzle for a instant freezer, comprising a plurality of V-shaped flow guide grooves (1) which are uniformly arranged in parallel in a moving direction of a frozen product conveyor plate belt (3), and slotted nozzles which communicate with the lower ends of the V-shaped flow guide grooves; each V-shaped flow guide groove includes two strip plates which are disposed in a relatively oblique way; the cross sections of the V-shaped flow guide grooves are rectangular, and the longitudinal sections of the V-shaped flow guide grooves in the width direction are inverted trapezoidal; the upper parts of every two adjacent V-shaped flow guide grooves are connected by means of a flat plate; and each slotted nozzle comprises two strip plates arranged in parallel relatively, the upper ends of the two strip plates of each slotted nozzle are respectively connected with the lower ends of the two strip plates of the corresponding V-shaped flow guide groove. The beveled slotted nozzle is formed by symmetrically beveling from the center point of the lower ends of the two strip plates of each slotted nozzle to two ends. The beveled slotted nozzle for the instant freezer can effectively improve the cooling uniformity of frozen products during cooling process, and reduce the relatively large difference in the cooling rate of frozen products at different positions in the food freezing process using a traditional structure, thereby improving the quality of frozen products.
