TH37808B - Continuous transfer type freezer - Google Patents

Abstract

DC60 (18/12/55) is a continuous transfer freezer for cooling or freezing items such as food items that are transported on conveyor belts by spraying. Cool air from the long nozzles onto the object is provided. In which the air beams gushed at In that case, a thin layer of cooled air is created on the surface of the object in order to Successful transfer of increased heat And the exhaust passageway will be created without affecting To the cooling function Several long slit nozzles 5a, 6a are placed near With above and under the conveyor belt along the belt flow direction, where each nozzle 5a 6a is shaped with angled parallel inlets and a trailing back to provide The cooled air is aligned in the inlet and ejected from the A high speed nozzle opening and a 12 exhaust passageway are created between each long nozzle so that The cooled air escapes from the nozzles and enters the two endpoints of the conveyor belts. Unloading on transport belts by spraying Cool air from the long nozzles onto the object is provided. In which the air beams gushed at In that case, a thin layer of cooled air is created on the surface of the object in order to Successful transfer of increased heat And the exhaust passageway will be created without affecting To the cooling function Several long slit nozzles 5a, 6a are placed near With above and under the conveyor belt along the belt flow direction, where each nozzle 5a 6a is shaped with angled parallel inlets and a trailing back to provide The cooled air is aligned in the inlet and ejected from the nozzle opening at high speed, and a 12 exhaust pass is produced between each long nozzle. The air rushing the nozzle will flow into the two endpoints of the conveyor 2.

Claims (7)

1.Continuous transfer freezers that consist of a case with an opening that forms an entrance And exit openings, transport belts for the transfer of cooled items from the compartment The openings are through the enclosures, a cool air recirculation mechanism consisting of a cooler and blowing fan, and a long nozzle for directing cool air to the Refrigerated item Where the nozzle at A long top and several lower long nozzles are placed close to each other. Above and under the conveyor belt in the direction of the belt flow with a long slit of Each nozzle is perpendicular to the belt flow direction. And a passage through the exhaust will be built for Perpendicular to the belt flow direction between each longitudinal nozzle to pilot The cooled air is directed from the longitudinal nozzles to both endpoints. Of the transport belt 2. Freezer continuous transfer type according to claim 1, where the nozzle is a long slot It is shaped to have an entrance consisting of a slender passageway and a parallel passage that follows it. 3.Continuous transfer freezer according to claim 1, where air circulation is performed. To occur in such an enclosure where the cooled air flows out of the blown fan. Mention the space above the longitudinal nozzle in the casing. A large volume of The cooled air flows through the long nozzle above it so that it is cooled. It is ejected from the long nozzle on the top and is released through the exhaust. While the rest of the cooled air flows to the longitudinal nozzles below. Through a guide tube with openings at both endpoints of the transport belt. In order to be ejected from the nozzle a long slit below it was released by Through the said exhaust and the exhausted air is returned to the chiller. 4. Freezer of the continuous transfer type according to claim 1, through which the exhaust will be This creates a recess between the long nozzles. 5. Freezer continuous transfer type according to claim 1 where the leading tip of the nozzle at It is such a long hole that is positioned close to the entrance opening or opening. The outlet of the casing is tilted according to the pressure difference between the channels. Open both channels 6. Freezer continuous transfer type according to claim 1, where the nozzle is a long channel. Several are incorporated into a long slot nozzle unit. 7. Continuous-transfer freezer according to claim 1, where the long nozzle unit at It consists of several longitudinal nozzles and is positioned over the belt. The carriage is placed on the arranged frame at both end of the conveyor belt.
