Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of poultry meat processing equipment, and in particular to an integrated device for rapid cooling and sterilization of boiled salted goose, which is applicable to the food safety control process in the large-scale production of salted goose. Background Technology
[0002] Salted goose, a traditional cooked poultry product, is beloved by consumers for its savory and flavorful taste and tender, firm meat. Its processing mainly includes raw material pretreatment, braising in a secret marinade, and cooling and shaping. Traditional cooling methods typically combine natural cooling with cold storage pre-cooling. The braised goose is laid flat in a ventilated environment to allow natural heat dissipation to reach 60-80°C, then transferred to a 0-4°C cold storage for forced cooling. This method is highly dependent on ambient temperature and humidity, involves cumbersome manual operation, and takes 4-6 hours in summer and 2-3 hours in winter, with an overall cooling cycle of 6-8 hours. This results in low cooling efficiency and an imbalance in the marinade's permeability gradient, leading to an overly salty surface and insufficient flavor penetration inside. Furthermore, freshly braised geese still contain a significant amount of marinade, which acts as a microbial culture medium. During cooling, the open environment easily leads to excessive bacterial counts. Cold storage pre-cooling only inhibits microbial growth but cannot eliminate existing biological contamination, resulting in inconsistent quality control of salted goose.
[0003] Existing technologies have implemented some improvements, such as forced air cooling or vacuum cooling. Forced air cooling can significantly increase the water loss rate on the surface of the goose, affecting the taste of the goose meat. The negative pressure created by vacuum puts pressure on the goose meat, causing muscle fibers to break, which also affects the taste of the goose meat and increases equipment investment and production costs. Utility Model Content
[0004] The purpose of this invention is to overcome the deficiencies in the existing technology and provide a salt-water goose cooling and sterilization machine that integrates rapid cooling and efficient sterilization to complete the rapid cooling and sterilization process of salt-water goose, improve cooling efficiency, and ensure stable quality control and food safety of salt-water goose.
[0005] The purpose of this utility model is achieved as follows: A brine goose cooling and sterilization machine includes a casing, a control mechanism on one side of the casing, a refrigeration mechanism inside the casing behind the control mechanism, a return water collection chamber below the control mechanism, a cooling chamber inside the casing on the side of the control mechanism, a motor on the top of the casing, a rotating shaft connected to the output shaft of the motor driving into the casing, a suspension bracket at the lower end of the rotating shaft, several hooks on the suspension bracket, a fan connected to the cold air outlet of the refrigeration mechanism on the rear wall of the cooling chamber, a sterilization mechanism on the left and right side walls of the cooling chamber, a water collection tray at the bottom of the cooling chamber, and the water collection tray connected to the return water collection chamber through a return water pipe.
[0006] In operation, the braising geese are suspended in the cooling chamber, the chamber door is closed, and the cold air temperature, UV sterilization cycle, and total cooling time are set through the control mechanism. The equipment is then started, and a pre-cooling stage is first performed. The fan is set to run at high speed, and the surface temperature of the goose is reduced from 80°C to 25°C within 10 minutes. Then, the UV sterilization mechanism is started, the fan is adjusted to medium speed circulation, and the UV lamps irradiate the goose from both sides of the body in a pulsed manner for 5 minutes. During the cooling and sterilization process, the suspension frame is rotated by a motor to ensure that the braising geese are evenly irradiated by the UV lamps. After sterilization, the cooling temperature is set to stabilize at 4°C, and cooling continues for 40 minutes until the center temperature of the goose drops to 8°C.
[0007] Compared with existing technologies, this device can rapidly cool down the braising geese in salt water, and sterilize them at the same time to prevent bacterial growth, greatly shortening the cooling time and improving cooling efficiency. The temperature and sterilization time of the cooling mechanism can be easily adjusted through the control panel. It is simple to operate and easy to learn, greatly improving production efficiency and reducing the workload of workers.
[0008] Furthermore, the sterilization mechanism includes ultraviolet lamps symmetrically arranged on the left and right side walls of the cooling chamber. The sterilization mechanism is electrically connected to the control mechanism via a circuit. During the sterilization operation, the ultraviolet lamps are pulsed, with a wavelength of 265nm, an intensity of 40mW / cm², and a duration of 60s.
[0009] Furthermore, the refrigeration mechanism includes a compressor, a condenser, an expansion valve, and an evaporator, which are interconnected by pipes inside the casing. The compressor compresses the refrigerant into a high-pressure gas. The high-pressure gas is transported to the condenser through pipes, where it releases heat and transforms into a high-pressure liquid. The high-pressure liquid is then transported to the expansion valve, where its pressure and temperature decrease, becoming a low-pressure liquid. Finally, it evaporates into a gas in the evaporator, absorbing heat from the surrounding environment to generate cold air. This cold air is then transported into the cooling chamber through internal pipes. The fan improves the efficiency of the cold air delivery. The refrigeration mechanism is electrically connected to the control mechanism via wiring.
[0010] Furthermore, a lighting lamp is provided on each side of the top of the cooling chamber, and a temperature measuring probe electrically connected to the control mechanism is provided on the side of the lighting lamp.
[0011] Furthermore, the front side of the cooling chamber is connected to a double-door via a hinge. When closed, the outer surface of the door is flush with the outer surface of the front side of the chamber, and the door is also equipped with a handle for opening and closing the door.
[0012] Furthermore, the door is made of vacuum-insulated glass, and magnetic sealing strips are provided at the connection between the door and the chassis.
[0013] Furthermore, the chassis has a double-layer hollow insulation structure, the outer shell of the chassis is made of 304 stainless steel, and the inner layer of the chassis is equipped with a food-grade polyurethane foam layer.
[0014] Furthermore, the surface of the water collection tray is coated with a hydrophobic coating.
[0015] Furthermore, the control mechanism includes a control panel fixedly mounted on the outer surface of the chassis, and multiple operation buttons are provided below the control panel. Attached Figure Description

[0020] The sterilization mechanism includes ultraviolet lamps 8 symmetrically arranged on the left and right side walls of the cooling chamber 2. The sterilization mechanism is electrically connected to the control mechanism via a circuit. During the sterilization operation, the ultraviolet lamps 8 are pulsed, with a wavelength of 265nm, an intensity of 40mW / cm², and a duration of 60s.
[0021] The refrigeration mechanism includes a compressor, condenser, expansion valve, and evaporator, which are connected to each other through pipes inside the casing 1. The compressor compresses the refrigerant into a high-pressure gas. The high-pressure gas is transported to the condenser through pipes and releases heat to become a high-pressure liquid. The high-pressure liquid is then transported to the expansion valve, where its pressure and temperature decrease, becoming a low-pressure liquid. Finally, it evaporates into a gas in the evaporator, absorbing heat from the surrounding environment to produce cold air. This cold air is then transported to the cooling chamber 2 through internal pipes. The efficiency of cold air delivery is improved by a fan 9. The refrigeration mechanism is electrically connected to the control mechanism via wiring.
[0022] A lighting lamp 10 is provided on each side of the top of the cooling chamber 2. A temperature probe 15 electrically connected to the control mechanism is provided on the side of the lighting lamp 10. The temperature probe 15 is used to detect the internal temperature of the cooling chamber 2, which facilitates the control of the cooling temperature.
[0023] The cooling chamber 2 has a double-door 11 connected to the front of the chassis 1 via a hinge.

[0024] The chassis 1 has a double-layer hollow insulation structure. The outer shell of chassis 1 is made of 304 stainless steel, and the inner shell of chassis 1 is equipped with a food-grade polyurethane foam layer. The insulation structure of chassis 1 helps to maintain the cooling temperature inside the cooling chamber 2 and prevents the external ambient temperature from affecting the cooling process of the salt water goose.
[0025] The surface of the water collection tray 6 is coated with a hydrophobic coating, which reduces the retention time of the brine in the brine and makes it easier to clean the water collection tray 6.

The cooling mechanism's outlet temperature is set to 0-4℃, the sterilization cycle of the UV lamps 8 is set, and the total cooling time is set via the control panel 13. The fan 13 is set to high speed, reducing the surface temperature of the goose from 80℃ to 25℃ within 10 minutes. Simultaneously, the UV sterilization mechanism is activated, the fan is adjusted to medium speed circulation, and the UV lamps irradiate the goose from both sides in a pulsed manner at an intensity of 40mW / cm², with each irradiation lasting 60 seconds and a duration of 5 minutes. During the cooling and sterilization process, the hanging frame 4 is rotated via the motor 3 to ensure uniform UV irradiation of the braising geese. After sterilization, the cooling temperature is set to a stable 4℃, and cooling continues for 40 minutes until the center temperature of the goose drops to 8℃. A water collection tray 6 is installed at the bottom of the cooling chamber 2 to collect some of the braising liquid dripping from the braising geese and discharge it into the return water collection chamber 7. This device allows for batch cooling of salted geese immediately after braising, significantly reducing cooling time compared to natural air cooling and improving cooling efficiency. Simultaneous sterilization during cooling prevents bacterial growth and enhances the safety of salted goose products. The device is simple in structure, easy to operate and control, and readily available, greatly improving production efficiency and reducing manual labor.
