Description

Technical Field

[0001] This invention relates to the field of refrigeration equipment technology, specifically a cold storage for rapid cooling of broiler chickens. Background Technology

[0002] Cold storage is a warehousing facility that maintains a constant temperature and humidity environment through artificial refrigeration technology. It is mainly used for the preservation, refrigeration, and long-term storage of food, medicine, chemical raw materials, and other items. However, slaughtered chickens are prone to rapid spoilage due to their own enzymatic reactions and microbial growth, which directly threatens meat quality safety. Therefore, rapid cooling is the core means to block this process. By quickly lowering the meat temperature to the threshold of microbial reproduction inhibition, enzyme activity can be effectively slowed down, bacterial proliferation can be inhibited, and meat quality deterioration can be delayed.

[0003] However, the existing technology has the following shortcomings: some cold storage facilities currently used for cooling broilers have design flaws: cold air is only blown locally and directionally from the top or side, and the airflow coverage is uneven, resulting in large differences in the rate of heat loss of broilers. In particular, the thick muscle parts such as the breast and legs have slow heat conduction and less contact with cold air, resulting in delayed cooling and uneven temperature distribution. Moreover, these parts are prone to retaining a temperature environment suitable for the growth of microorganisms, which can exacerbate local deterioration. Summary of the Invention

[0024] The present invention will be further described below with reference to the accompanying drawings: Example 1: As shown in the attached document Figure 1 To be continued Figure 7 Appendix Figure 10 As shown: This embodiment provides a rapid cooling cold storage for broilers, including a cold storage 1. An even number of refrigeration fan units 2 are installed on the top of the cold storage 1. A storage room 11 is set inside the cold storage 1. Several storage doors 12 are installed on the storage room 11. A cold storage inlet and outlet 13 are installed on the front surface of the storage room 11. A cooling device 15 is set behind the cold storage inlet and outlet 13. A conveying and suspension assembly 14 is installed inside the cooling device 15.

[0025] Furthermore, warehouse 11 is equipped with doors 12 on the front and left and right sides to allow access to warehouse 11 for maintenance, thereby enabling the inspection and troubleshooting of the cooling device 15 in warehouse 11.

[0026] Furthermore, the cold storage entrance and exit 13 are divided into import and export sections, used for conveying the suspension components 14 in and out, thereby facilitating the hanging of slaughtered chickens for rapid cooling.

[0027] The cooling device 15 includes a U-shaped tunnel 151, a first air-cooling hood 152 installed on the top of the U-shaped tunnel 151, a second air-cooling hood 154 arranged parallel to the first air-cooling hood 152, a guide conveyor hood 153 connecting the first air-cooling hood 152 and the second air-cooling hood 154, and a maintenance ladder 155 installed on the outer wall of the U-shaped tunnel 151.

[0028] Furthermore, the U-shaped tunnel 151 is in the shape of a "U". The first air-cooled cover 152 and the second air-cooled cover 154 are connected to the independent cooling fan unit 2. The distribution conveyor cover 153 uses the first air-cooled cover 152 and the second air-cooled cover 154 to distribute the cold air input.

[0029] The conveying suspension assembly 14 is equipped with an auxiliary transfer track 141, on which several suspension cables 142 are installed, and several moving clamps 143 are installed on the auxiliary transfer track 141.

[0030] Furthermore, the auxiliary transfer track 141 is mainly adapted to the shape of the U-shaped tunnel 151, and then the connection inside the U-shaped tunnel 151 is completed by a portion of the suspension cable 142, while the auxiliary transfer track 141 set outside the U-shaped tunnel 151 is suspended from the roof of the factory building by the suspension cable 142.

[0031] Furthermore, the suspension cable 142 is divided into two types, long and short. The long type is suspended from the roof of the factory building, while the short type is used to form a fixation on the inner surface of the U-shaped tunnel 151.

[0032] Furthermore, the mobile fixture 143 is mainly driven by a chain, which is uniformly driven by the chain drives within the field area.

[0033] The U-shaped tunnel 151 contains an inner cavity 1511, in which several sets of return guide components 1512 are installed. An input device 1513 is installed at the top of the inner cavity 1511. Several support rods 1514 arranged in a straight line are fixed on the outer wall of the return guide components 1512. An even number of guide frames 1515 are fixed on the support rods 1514. An inner guide groove 1516 is provided at the bottom of the inner cavity 1511. An inward discharge groove 1517 is provided in the middle section of the inner guide groove 1516. A cover 1531 is provided inside the distribution conveying cover 153.

[0034] Furthermore, the inner cavity 1511 is in the same shape as the U-shaped tunnel 151, and at least three sets of input devices 1513 are opened at the top. The input devices 1513 are directly below the conveyor suspension assembly 14, which outputs cold air to the slaughtered broilers suspended on the conveyor suspension assembly 14.

[0035] Furthermore, the cavity guide groove 1516 has a certain clear angle, and the cavity guide groove 1516 is set at both ends of the concave discharge groove 1517. The concave discharge groove 1517 is directly above the distribution guide cover 153, which can realize the water flow outward.

[0036] Furthermore, the guide frame 1515 is fixed on the support rod 1514 to limit the suspended broiler chicken in the inner cavity 1511 of the input channel, preventing it from swinging significantly during the process of being blown by cold air, and the opening is in an outward expansion state, forming an "eight" state with another guide frame 1515.

[0037] The return guide assembly 1512 has a U-shaped guide cavity 15122, a partition baffle 15123 is fixed in the center of the U-shaped guide cavity 15122, an oblique air vent 15121 is formed at the top of the U-shaped guide cavity 15122, and a blower shroud 15124 is provided at the end of the U-shaped guide cavity 15122. Several adjustable louvers 15125 are installed in the blower shroud 15124.

[0038] Furthermore, the U-shaped guide cavity 15122 is mainly formed in the return guide assembly 1512. The center of the U-shaped guide cavity 15122 is separated by the partition baffle 15123, and the return guide is formed in the U-shaped guide cavity 15122 after the cold air is input.

[0039] Furthermore, the blower shroud 15124 is mainly used for air output. Together with the U-shaped guide cavity 15122, the cold air output is guided and fully contacts the thick muscle parts of the broiler, such as the breast and legs, to achieve precise cooling.

[0040] Furthermore, the adjustable louvers 15125 installed in the blower shroud 15124 are mainly adjusted manually. By swinging, the adjustable louvers 15125 can be positioned at different angles to achieve different orientations and positions on the broiler's body.

[0041] The input device 1513 is equipped with an arched cover 15131. An even array of adjustable exhaust fans 15132 are installed on the inner wall of the arched cover 15131. A diversion and guiding block 15133 is arranged between the even array of adjustable exhaust fans 15132. A connecting sleeve 15134 is fixed above the arched cover 15131. An oblique air outlet 15135 is provided below each of the adjustable exhaust fans 15132.

[0042] Furthermore, at least two sets of adjustable exhaust vents 15132 are provided inside the arched cover 15131, and the exhaust fans on the adjustable exhaust vents 15132 are staggered with the exhaust fans on the other adjustable exhaust vents 15132 to avoid the enhanced cold air from creating a countercurrent.

[0043] Furthermore, the diversion and guiding block 15133 is mainly used to divide the air inside the arched cover 15131 into two channels, and the two channels, in conjunction with the regulating exhaust fan 15132 installed between the channels, form a cold air output.

[0044] Furthermore, the inclined air outlet 15135 is tilted at 45°, with its lower part directly facing the inclined air vent 15121. The cold air is received by the inclined air vent 15121 and, with the cooperation of the U-shaped guide cavity 15122, forms a secondary output of cold air.

[0045] The specific working principle is as follows: This invention utilizes the pneumatic operation of the refrigeration fan unit 2 at the top of the cold storage 1 to generate cold air. Simultaneously, the cold air is fed into the cooling device 15 inside the storage room 11 via a cold air blower. After slaughter, the broiler chickens are carried by a moving clamp 143 on an auxiliary transfer track 141 suspended by a cable 142, entering through the inlet of the cold storage entrance / exit 13 and exiting through the outlet. The cold air is fed into the first air-cooled hood 152 and the second air-cooled hood 154. The first and second air-cooled hoods 152 and 154 precisely divert a portion of the cold air into a diversion conveyor hood 153. All three simultaneously supply cold air to the arched hood 15131. The diversion conveyor block 15133 splits the incoming cold air in two, which is then controlled by the exhaust fan 15132. The exhaust fan draws in the cold air, which is then blown out from the oblique air outlet 15135. The cold air blown out is directed downwards at a 45° angle from the broiler. The cold air is received by the oblique air vent 15121 below and enters the U-shaped guide cavity 15122 separated by the partition baffle 15123 before being output from the air guide cover 15124 at the end. With the adjustment of the angle of the adjustable louvers 15125 inside the cover, the cold air is output to the thick muscle parts of the broiler, such as the breast and legs, to fully contact and cool them down. The suspended broiler is limited by the guide frame 1515 fixed to the surface of the support rod 1514. The water droplets on the chicken fall into the guide groove 1516 inside the cavity and flow into the concave discharge groove 1517 to achieve external guidance.

[0046] Example 2: As shown in the attached document Figure 1 To be continued Figure 3 Appendix Figure 8 To be continued Figure 9 As shown: The cold storage unit 1 is equipped with an even number of refrigeration fan units 2 on its top. Inside the cold storage unit 1 is a storage room 11 with several doors 12. A cold storage inlet / outlet 13 is installed on the front surface of the storage room 11. A cooling device 15 is installed behind the cold storage inlet / outlet 13, and a conveyor suspension assembly 14 is installed inside the cooling device 15. A U-shaped tunnel 151 is installed inside the cooling device 15. A first air-cooling hood 152 is installed on the top of the U-shaped tunnel 151. A second air-cooling hood 154 is positioned parallel to the first air-cooling hood 152. A guide conveyor hood 153 connects the first air-cooling hood 152 and the second air-cooling hood 154. A maintenance ladder 155 is installed on the outer wall of the U-shaped tunnel 151.

[0047] The first air-cooled shroud 152 is provided with a duckbill shroud 1521, which is embedded with a spoon-shaped partition block 1522. An air supply cavity 1523 is formed inside the duckbill shroud 1521, and several air swing components 1524 are installed in the air supply cavity 1523. A connecting pipe 1525 is connected to the side wall of the duckbill shroud 1521. A cover 1531 is provided inside the distribution and conveying shroud 153. A connecting pipe 1532 is installed at both ends of the cover 1531. An inner guide cavity 15221 is formed inside the spoon-shaped partition block 1522.

[0048] Furthermore, the duckbill cover 1521 is mainly used to connect the air cooler that outputs cold air in the refrigeration fan unit 2, thereby forming a nested seal on the surface of the air cooler.

[0049] Furthermore, a spoon-shaped partition block 1522 is provided above the air supply cavity 1523, and the spoon-shaped partition block 1522 forms an inner guide cavity 15221 with the duckbill cover body 1521, thereby allowing the input cold air to be output through the two cavities.

[0050] Furthermore, the connecting pipe 1525 is mainly used to connect with the connecting pipe 1532, so that the cold in the inner guide cavity 15221 can be introduced into the cover 1531 with the cooperation of the connecting pipe 1525 and the connecting pipe 1532.

[0051] The wind swing assembly 1524 includes a rotating column 15242, a rotating cap 15241 on the top of the rotating column 15242, a wind swing plate 15243 embedded in the center of the rotating column 15242, side blocks 15244 on both sides of the wind swing plate 15243, and arc-shaped support springs 15245 installed on the inner wall of each side block 15244.

[0052] Furthermore, the bottom of the rotating column 15242 is nested within the inner surface of the duckbill cover body 1521, while the upper column rod passes through the spoon-shaped partition block 1522 and is connected to the rotating cap 15241 for auxiliary rotation.

[0053] Furthermore, the wind swing plate 15243 is formed in the shape of an arc block and is fixed on the rotating column 15242. The two sides are connected by arc-shaped support springs 15245, so that the arc-shaped support springs 15245 can be used to close the wind swing plate 15243 during the swing process.

[0054] Furthermore, the side block 15244 is mainly used to fix the end of the arc-shaped support spring 15245, so that the arc-shaped support spring 15245 can support the wind swing plate 15243, and at the same time, it can also limit the maximum swing angle of the wind swing plate 15243.

[0055] The specific working principle is as follows: In this invention, a refrigeration fan unit 2 installed on the top of the cold storage 1 is connected to the storage room 11 and the first air-cooled cover 152 and the second air-cooled cover 154 on the internal cooling device 15. The duckbill cover body 1521 nests and seals the front of the refrigeration fan. After the cold air is input, it is guided by the inner guide cavity 15221 formed on the spoon-shaped partition block 1522 and the air supply cavity 1523 below the spoon-shaped partition block 1522. The cold air in the inner guide cavity 15221 is input into the cover through the connecting pipe 1525 and the connected connecting pipe 1532. In section 1531, cold air is directed and precisely distributed, reducing the number of refrigeration fan units. The cold air entering the air supply chamber 1523 blows the wind vane 15243 on the rotating column 15242. Under the swing of the wind vane 15243, the arc-shaped support springs 15245 on both sides are irregularly compressed. The arc-shaped support springs 15245 rebound due to their own elasticity, and then the wind vane 15243 changes the different cold air input directions, filling all corners of the arched cover, and better realizing the subsequent cold air delivery.
