Method of dropping chilled broilers {SCALDING METHOD FOR COLD-STORAGE CHICKEN}

The present invention relates to a method for wetting a broiler for refrigeration broiler, and more particularly, to a method for wetting of broiler broiler for immersing the broiler for a certain time in a boiling water to facilitate the removal of feathers of broiler chicken. .

Conventional wet method has been using the immersion scalding method of immersing the object such as broiler in hot water, and recently, some of the drying method using spray steam or microwave energy.

    Of course, the wetting process is carried out after the object has passed through the fainting and bleeding process, and is typically immersed for a period of time at a water temperature in the range of about 50 to 65 ° C. to facilitate hair loss, which is the goal of the wetting process, while the object is heated. Efforts have been made to reduce organizational degeneration by

    The most important thing in the wetting process is the wetting temperature, followed by the wetting time. The higher the wetting temperature, the better the feathers are drawn, but the more likely the conductor surface is denatured by heat, and the likelihood of discoloration (yellowing) during storage. Will increase.

    In addition, the broiler (under 8 weeks), roaster (under 10 weeks), capon (under castrated male under 5 months), stag (under 10 months) , hen (11-15 months female), broiler mother (14 months or less), cock (males over 10 months), etc. are classified commercially by economic value. The broilers to be refrigerated and the broilers to be refrigerated will also have different conditions.

    In general, weeding of chilled broilers is carried out at low temperatures, and weeding of frozen broilers is carried out at high temperatures, it is important to maintain a moisturized state on the surface of the conductor in order to prevent the reduction of the flue due to discoloration or surface drying during storage.

    In addition, as a method for preventing mutual contamination of microorganisms when wetting, spraying sterilization liquid using spray steam, counter-current scalding that prevents contamination by moving the conductor and the splashing liquid in the opposite direction. There is a multi-stage scalding method that prevents contamination by going through several tumble baths.In order to prevent the contamination of the conductor during the tumble we need to change the tumble water frequently or keep the pH of the tumble water below 6.0. (Salmonella) bacteria are resistant to heat and can survive in conditions above pH 6.0.

    In addition, Escherichia coli, Salmonella enteritidis, Salmonella typhimurim, Campylobacter jejuni, Campylobacter coli and Campylobacter colier mobile bacterial forms such as lari, and for example, Listeria monocytogenes (Pseudomonas fluorescens), Pseudomonas aeruginosa (Pseudomonas aeruginosa), enterococcus pae There are many opportunities for exposure to various pathogens such as Enterococcus faecium and Staphylococcus aureus, so handling, processing and consuming infected poultry should be minimized if these pathogens cannot be prevented. do.

The present invention relates to the wetting method of refrigerated broiler, strictly speaking to carry out the multi-stage wetting method among the immersion wetting method to facilitate hair loss, which is the purpose of wetting, and to provide a more hygienic wetting method. To improve the hygiene of the conductor.

The present invention relates to a method for wetting a broiler broiler for refrigeration, wherein the method of wetting the carcass which is a chilled broiler for which blood has been removed from livelihood is performed by immersing the carcass in a primary and a secondary tank to sequentially loosen the feathers. It features.

     In addition, the primary wet bath is immersed for 130 ~ 170 seconds at 47 ~ 49 ℃, after which the secondary wet bath is immersed for 120 ~ 160 seconds at 59 ~ 60 ℃ characterized in that the feather is loose.

Therefore, the present invention has a remarkable effect of facilitating the hair loss operation of the refrigerated broiler chicken, maintaining the wet water management and good hygiene of the conductor.

The present invention relates to a method for wetting the broiler broiler for refrigeration, in the method of wetting the conductor (30), which is the broiler for broiler meat from which blood is removed from the livelihood, by immersing the conductor in the primary and secondary tanks (11) sequentially. Characterized by loosening of feathers.

     In addition, the primary wet bath is immersed for 130 ~ 170 seconds at 47 ~ 49 ℃, after which the secondary wet bath is immersed for 120 ~ 160 seconds at 59 ~ 60 ℃ characterized in that the feather is loose.

     In addition, fresh water or recycled water is introduced into the primary and secondary tanks, and there is a continuous overflow of water from the tanks, and cross contamination of pathogenic bacteria in the tanks is prevented. Rinsate is supplied from a spray system downstream of the antimicrobial composition slightly below the total concentration for abatement, but at the beginning of the process, the trough is preferentially filled with fresh water containing the composition as shown in the total concentration. Characterized in that it is processed.

     In addition, the contaminants 31 present in the tumbled water 12 are raised to the top of the tumbled water by the bubble generators installed at the lower portions of the first and the second tumbled tanks. This is quickly discharged, characterized in that the overflowed water droplets are loaded into the contaminated water tank through a lower pipe installed outside the water tank.

     In addition, the primary and secondary tanks, the hot water inlet tube and the hot water inlet tube, the cooling water input tube into which the cooling water is introduced, the water droplet input tube into which the water droplets at a suitable temperature for the water droplets, antibacterial material or electrolytic water Disinfectant water input pipes are respectively installed on the top of the trough tank to be the end point of the wetting process, characterized in that the tumble water overflows continuously because the height of the trough tank becomes the point where the conductor is first introduced.

     In addition, the first and second tumble baths are characterized in that the dripping process is sequentially performed by immersing in the tumble water in the trough while the conductor is suspended by the shackle line 20.

     And it is characterized in that the addition of the electrolytic oxidation water of pH 3.0 ~ 5.0 in the first and second wetting process.

     The present invention will be described in detail with reference to the accompanying drawings. 1 is a flow chart showing the steps performed in the refrigeration broiler processing process, Figure 2 is an external picture of the tumbler, Figure 3 is a photo of the tumbler, Figure 4 is an internal photo of the upper side of the tumbler open.

       In the processing of refrigerated broilers, conveyors are used to transport livelihoods and conductors through various stages of the processing equipment. First, a live bird is put into an automated conveyor belt equipped with a deceleration motor, and a livelihood is placed on the shackle 21 one by one. It hangs facing the worker's chest.

The livelihood is then put into a choking which is exposed to electrical current; This stage is also known as the stunning stage. The livelihood is stunned by the electrical current being injected into their heads (primarily rice) in contact with the sterile solution at the bottom of the stunner. Such an electric shock is not severe enough to cause permanent damage or killing to the livelihood, and it is possible to fix the livelihood and allow the body to be sufficiently drooped in an automated slaughter device. The livelihood is suspended in the downward direction, and the neck is drooped by stunning.

       In the next step, the livelihood is bleeded by a blood circulation machine (killing machine) by an automated circulation blade in a processing step, and a blood bleeding tank is installed, and the bleeding blood is transferred to a blood transfer pump, and coagulated after heating.

       In the next step, after the blood is removed from the livelihood, it is sequentially immersed in two dropper or dropper tank 11 and immersed for 130 to 170 seconds in the dropper or dropper tank of 47 ~ 49 ℃ respectively 59-60 ℃ The feathers are loosened by being immersed for 120 to 160 seconds in the dropper or dropper tank. This process is called "scalding". The feathers and skin of the conductor are soaked in water so that the feathers are removed in the hair loss process. This process is particularly at risk of bacterial cross contamination as the conductor is immersed in a normal bath.

       Fresh or recycled water is added to the conductor entering the bath, and there is a continuous overflow of water from the bath. The trough may also supply a rinsate from a spray system downstream with an antimicrobial composition slightly below the total concentration to reduce cross contamination of pathogenic bacteria in the trough. At the beginning of the process, the trough is preferentially filled with fresh water comprising the composition as set forth above in total concentration and then treated.

       In addition, the bubble tank is installed in the lower bubble generator, the hot water inlet tube, the hot water inlet tube, the cooling water inlet tube, the cooling water inlet, the water droplets tube of the appropriate temperature to the water droplets, antibacterial Disinfectant water input pipes into which material or electrolytic water is injected are installed at the upper part of the trough tank at the end of the wetting process, and the height of the trough as the first point at which the conductor is injected is low so that the number of troughs overflows continuously. To become a structure.

       In addition, the bubble generator installed below the tumble tank 11 is composed of an air pump and a pipe formed with air holes in the upper surface, the pollutant 31 present in the water droplets 12 by the bubble generating device The contaminant is quickly discharged to the point where the water flow overflows, and the overflowed water flows with some feathers, less removed blood, feces and various foreign objects. The flowing sewage water is loaded into the contaminated water tank through a lower pipe installed outside the water tank.

       In addition, on the drip tank, the conductor is immersed in the drip water 12 in the tumble tank 11 while being suspended by the shackle line 20 so that the first and second drip processes proceed sequentially.

       Also, if the wetting process is not working due to the high or low temperature, all the lines of the wetting process should be stopped, and the conductors in the wetting machine should be taken out of the wetting machine immediately. It is natural.

       In the present invention, the reason for carrying out the splitting process in two stages is generally that the body temperature of living is quite high, such as 40.6-41.7 ° C. After slaughtering the livestock, the body temperature drops and post-change occurs immediately after the first step. It enters the process of water soaking and soaks in the water of 47 ~ 49 ℃, so that the inside and outside temperature of carcase is raised gently, so that the carcasses are washed and disinfected first while the protein and fat denaturation in carcase are less generated. In the process of tea wetting, we have a real wetting process for removing feathers.

In addition, in the present invention, the electrolytic oxidized water of pH 3.0 to 5.0 can be added and used in the first and second wetting process. The electrolytic oxidized water contains chlorine ions, so as to disinfect, clean, and moisturize. Since the concentration of water below pH 6.0, Salmonella is difficult to survive.

       In other words, the wet drip is a process that is easy to cross-contaminate due to the simultaneous operation of the bleeding-conductors, and ammonium urate or uric acid remains in the wet drip water due to melting of manure. Since it is easy to increase the pH of more than 6.0, and in the pH conditions Salmonella (salmonella) is resistant to heat and can survive, so often the water must be replaced with clean water.

       Next, a depilation process and a head removal process are performed. That is, the preen gland is removed, and a venting device cuts around the vent or anus of the algae, removing about 23 mm from the individual by the possibility of any fecal mater remaining. . Spraying of chlorinated water is applied to such a device to prevent contamination of the algae's skin from feces.

       Conventional methods for spraying conductors are known experimentally that about 148 mL of fungicide is required to achieve an effective effect. The next device is the eviscerator. It uses a spoon-shaped device that pulls internal organs out of the body. Such devices are generally equipped with chlorinated water sprayers and maintain internal organs from contact with the outside of poultry. Such a device not only removes internal organs or "viscera" from the carcass as a whole, but also gently "internally wraps" on the back of the bird and is investigated by the investigator for possible disease.

       The investigator reviews the whole poultry, including the intestinal packaging. After the investigator has examined the poultry whole with viscera packaging, the viscera are removed from the carcass and discarded in the same offline trough with previously recovered unknown wire, head and neck. In the same device, the gizzard, heart and liver are collected from the poultry for consumption.

       After irradiation and visceral removal, fully viscera extracted conductors with legs suspended by the shackle line 20 clean the interior and exterior of the conductors, commonly referred to as "conduits without conductors". The conductor passes through at least one "inner / outer conductor washer" while still being transported onto the conveyor system.

       This system consists of a stainless steel cabinet designed for automated cleaning of conductors. Water is used for washing inside and outside each conductor. All the water used in the cleaning cabinet here is directed to the waste line.

Thus, the used wash water, the water continuously used to clean the viscera extractors, the water from the hand and knife cleaning devices, and fresh water if necessary, are used to transport the non-edible material through the waste bins and enter the waste water.

The washing process involves not only the inside of the poultry but also the outside. During the cleaning process, a predetermined content of antimicrobial composition is sprayed onto the conductor. Runoff may be collected and fed to the trough for reuse.

Accordingly, the antimicrobial composition along with fresh water is supplied counter-current to the direction of the conductor. They are then reused in the bath or are added to the waste water. If desired, it is known that concentrations of about 200 to about 600 ppm of the antimicrobial composition are effective for water, although the concentration of the antimicrobial composition may vary depending upon the application.

       In addition, when electrolytic alkali water having a pH of 7.5 to 10.5 is added in the washing step, the first refrigeration step, and the second refrigeration step before the refrigeration process, the electrolytic alkali water is easily absorbed and penetrated through the chicken surface, and rapidly diffuses into the cell tissue. The amount of repair is increased by the electrolytic alkali water diffused into the chicken and the meat is very soft.The minerals (cationic: calcium, magnesium, potassium ions, etc.) contained in the electrolytic alkaline water enter the chicken and act as alkali generating elements. It contains more alkali-producing elements, and when ingested, it becomes an alkaline food that produces alkali in our body.

       The next unit is a refrigeration unit for the cooling of the conductor, which is automatically immersed for about five minutes in a large tank called the first-chiller.

       The next device is a secondary chiller, the conductor is also immersed in cooling water of 18 ~ 22 ℃ about 5 minutes, the third chiller is also immersed in cooling water of 8 ~ 13 ℃ temperature about 5 minutes, the 3 Chlorine water is applied to the coolant in the chiller, and finally, the conductor is immersed in the coolant at a temperature of 6-9 ° C for about 5-7 minutes in the fourth chiller.

       The water in the chillers may be installed with a bubble generator so that it is actively aerated to increase the freezing capacity and absorption of water to help the movement of the water.

       This aeration process, together with the large amount of fat present in the water of the chillers, forms a flocculating material floating on top of the cooling water. Such materials are generally referred to as "chiller skimmings" and are subsequently removed from the water of the chillers and transferred to a waste line.

       The conductor is allowed to have a total of 8% additional moisture, through which the conductor absorbs about 4% to about 5% additional moisture. When passing through a drip drum (dehydrator) with a device to reduce excess absorbed moisture, the conductor is suspended again on another shackle line to be transferred to another area of the device.

       The conductor is sorted according to the weight by the sorting device in which the load cell is installed, and is subjected to the packing process by the packing machine.
