Description

Technical Field

[0001] The invention belongs to the technical field of food processing, in particular to a large-scale continuous braising system. Background Art

[0002] Soft-boiled eggs are a popular food, and their production process is crucial to achieving a soft-boiled egg. Maintaining the fluidity of the yolk is crucial, primarily through controlling the braising process. Currently, most braising processes use high temperatures, which creates problems. High temperatures can easily cause the yolk to solidify, making it difficult to produce a soft-boiled egg. Maintaining the egg's structure requires prolonged braising. Furthermore, if the braising time is too short, the braising liquid won't penetrate the egg, compromising the egg's flavor.

[0003] From the perspective of cost, most soft-boiled eggs are braised in large quantities at one time, and it is not only difficult to braise high-quality soft-boiled eggs using some of the currently used braising pots and other equipment (which tests the braising process), but also the structure of the equipment itself makes it easy for eggs to break and difficult to clean. Braising large quantities of soft-boiled eggs requires a lot of manual assistance, which is inefficient and will obviously increase the operating cost of the equipment. Therefore, a large-scale continuous braising system suitable for braising soft-boiled eggs is proposed to solve the above problems. Summary of the Invention

[0004] In response to the above problems, the present invention provides a large-scale continuous braising system to solve the problems of poor quality of soft-boiled eggs braised by existing braising equipment, low processing efficiency due to the need for manual assistance, and the easy occurrence of broken eggs and difficulty in cleaning.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A large-scale continuous braising system includes a sealed braising container. The bottom discharge port of the braising container is connected to a solid-liquid separation device via a discharge pipe. A belt conveyor is provided on one side of the solid-liquid separation device for delivering separated eggs. The solid-liquid separation device is also connected to a mixing tank for collecting the separated brine. The brine processed in the mixing tank is delivered to the braising container via a pipeline for use.

[0007] The braising container is provided with a temperature detector for detecting the temperature inside the braising container. The top of the braising container is also connected with a pressure pipe for applying pressure to the braising container and a pressure release pipe for releasing pressure outward.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: by connecting the discharge side of the braising container to the solid-liquid separation device to separate the eggs and the brine, the manual salvage work can be reduced, and the discharge process can be completed quickly, and the brine can be introduced into the modulation tank for storage and processing after separation by the solid-liquid separation device. For large-scale processing of brine eggs, a faster production rhythm can be achieved, and the brine is transported through the discharge pipe and other pipelines, which can reduce contact with the outside air. When cleaning, it is only necessary to introduce the cleaning water and rinse it, and there will be no bacterial infection such as mold and odor, which reduces the cleaning workload. In the process of disinfection, it is only necessary to introduce high-temperature steam to achieve sterilization and disinfection of the equipment in the system, which is fast and convenient to handle. In addition, the braising temperature in the braising container is controlled by a temperature detector, and the braising container is pressurized through a pressure pipe. The braising is carried out in a low-temperature and high-pressure manner, so that the egg yolk will not solidify while ensuring the braising effect.

[0009] As a further improvement of the above solution, one end of the pressure relief pipe is connected to the energy accumulator, and the pressure relief pipe is connected to a first control valve for controlling its on and off;

[0010] The end of the pressure pipe is connected to a pressure pump, and the pressure pipe is connected to a second control valve for controlling the on-off of the pressure pipe.

[0011] The technical effect of the above improvement is that the pressure pump can be used to pressurize the braising container, and the energy accumulator can introduce the pressure in the braising container into the energy accumulator for storage when feeding materials out of the braising container, thereby reducing waste and speeding up the efficiency of subsequent pressurization.

[0012] As a further improvement of the above solution, a ball valve is provided on the discharge pipe to facilitate the control of outward discharge, a bend is provided between the ball valve and the discharge port at the bottom end of the braising container, and a straight pipe section is provided between the bend and the ball valve.

[0013] The technical effect of the above improvement is: the ball valve is mainly used to control the on and off of the discharge pipe to facilitate the discharge of materials after the braising is completed, and the set curved and straight pipe sections can form an air buffer zone between the brine and eggs in the braising container and the ball valve to prevent the eggs from being pressed on the ball valve and crushed.

[0014] As a further improvement of the above solution, a heat exchanger is provided between the modulation tank and the solid-liquid separation device, and a suction source is provided on the modulation tank for sucking the brine separated by the solid-liquid separation device into the modulation tank.

[0015] The technical effect of the above improvement is: the brine separated in the solid-liquid separation device is sucked into the modulation tank through the provided suction source, and heat is exchanged when passing through the heat exchanger to cool down the temperature of the brine.

[0016] As a further improvement of the above solution, it also includes a purification tank, which is provided with an air inlet pipe interconnected with the exhaust port on the top of the solid-liquid separation device, and the drain port at the bottom of the solid-liquid separation device is interconnected with the liquid inlet pipe provided on the purification tank;

[0017] Liquid is arranged in the purification tank, the port of the air inlet pipe is immersed below the liquid surface, and the port of the liquid inlet pipe is located above the liquid surface.

[0018] The technical effect of the above improvement is that through the purification tank provided, the brine vapor generated during discharge in the solid-liquid separation device and the cleaning water during cleaning can be introduced into the purification tank for filtration and purification, thereby avoiding direct discharge into the outside.

[0019] As a further improvement of the above solution, a bubbling device for bubbling and stirring the inside of the braising container is further provided on the outer surface of the braising container.

[0020] The technical effect of the above improvement is that the brine and eggs can be stirred by bubbling through the bubbling device, and this setting can avoid breaking the eggs during the stirring process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solution, the present invention is described in detail below in conjunction with embodiments. The description in this section is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0026] like Figure 1-3As shown, the specific scheme of this embodiment is: a large-scale continuous braising system, including a sealed braising container 10, in this application, the braising container 10 is a sealed tank, the bottom discharge port of the braising container 10 is connected to the solid-liquid separation device 11 through a discharge pipe 12, specifically, the solid-liquid separation device 11 includes a separation plate 111 for separating eggs and brine, the separation plate 111 is arranged obliquely, and a discharge door is provided on the lower side to facilitate taking the eggs out of the solid-liquid separation device 11, and the solid-liquid separation device 11 is provided with a discharge door A belt conveyor 13 is provided on one side for sending out the separated eggs. A filter screen 112 is provided below the separation plate 111 for performing the first filtration of the separated brine to remove broken eggs in the brine. A collecting hopper 113 for collecting and storing the brine is provided below the filter screen 112. A modulation tank 14 for collecting the separated brine is also connected to the solid-liquid separation device 11. The modulation tank 14 is connected to the drain outlet of the collecting hopper 113 through a pipeline. The brine treated in the modulation tank 14 is sent to the brine preparation container 10 through a pipeline for continued use.

[0027] Specifically, a steam pipe is provided on the braising container 10 for heating the brine in the braising container 10. A temperature detector 101 is provided on the braising container 10 for detecting the temperature in the braising container 10. The temperature of the brine in the braising container 10 is detected by the temperature detector 101 to achieve control of the brine temperature. Specifically, a PLC controller is used for control to avoid the egg yolk solidification caused by the high temperature of the braising container 10. A cold water pipe is also provided on the top of the braising container 10 for supplying cold water into the braising container 10 for warming. The top of the braising container 10 is also connected to a pressurizing pipe 103 for applying pressure to the braising container 10, and a pressure relief pipe 102 for releasing pressure to the outside.

[0028] One end of the pressure relief pipe 102 is connected to the accumulator 16, and the pressure relief pipe 102 is connected to a first control valve for controlling its on and off. In order to effectively control the air pressure in the marinating container 10, a pressure relief pump for outward pressure relief is also provided on the pressure relief pipe 102; the end of the pressure increasing pipe 103 is connected to the pressure increasing pump 15, and the pressure increasing pipe 103 is connected to a second control valve for controlling its on and off. In this application, a PLC controller is provided to control various valves, pumps and other components, and the temperature detector 101 provides a feedback signal for the controlled temperature. During the marinating process, when pressurizing, the pressure in the marinating container 10 is increased by starting the pressure increasing pump 15. Therefore, the eggs are marinated at a low temperature during the marinating process. The so-called low temperature refers to a temperature lower than that of traditional high-temperature marinating, which can avoid the temperature from heating and solidifying the egg yolk. Under the action of high pressure, the brine is pressed into the egg, thereby improving the marinating effect.

[0029] like Figure 2As shown, as a preferred embodiment of the above embodiment, a ball valve 121 is provided on the discharge pipe 12 for facilitating the control of outward discharge, and a bend 122 is provided between the ball valve 121 and the discharge port at the bottom end of the braising container 10. The specific bend 122 is an "S"-shaped bend, and a straight pipe section is provided between the bend 122 and the ball valve 121. During the specific braising process, and due to the bending effect of the bend 122, the brine and eggs can be prevented from directly entering the discharge pipe 12. Since the braising container 10 is in a high-pressure state, an air buffer column is formed in the straight pipe section of the discharge pipe 12. The air buffer column can prevent the eggs from directly hitting the ball valve 121 during the process of opening the ball valve 121 for discharge. The eggs will pass through the ball valve 121 only when the ball valve 121 is fully opened, so the air column in the straight pipe section forms a buffer zone.

[0030] like Figure 1 As shown, as a preferred embodiment of the above embodiment, a heat exchanger 17 is provided between the modulation tank 14 and the solid-liquid separation device 11, and a suction source 141 is provided on the modulation tank 14 for sucking the brine separated on the solid-liquid separation device 11 into the modulation tank 14. Specifically, the suction source 141 is a Roots blower. After starting the suction source 141, a negative pressure is generated in the modulation tank 14, so that the brine collected in the solid-liquid separation device 11 is introduced into the modulation tank 14 for treatment, and the heat exchanger 17 cools the recovered brine.

[0031] like Figure 1 As shown, as a preferred embodiment of the above embodiment, it further includes a purification tank 18, which is provided with an air inlet pipe 181 that is interconnected with the exhaust port at the top of the solid-liquid separation device 11, and a check valve is provided on the air inlet pipe 181 to prevent backflow. A control valve is provided at the exhaust port at the top of the solid-liquid separation device 11, and the drain port at the bottom of the solid-liquid separation device 11 is interconnected with a liquid inlet pipe 182 provided on the purification tank 18. The liquid inlet pipe 182 is also provided with a control valve, and the liquid inlet pipe 182 is connected to the pipeline connecting the solid-liquid separation device 11 and the modulation tank 14 through a tee. The liquid inlet pipe 182 is mainly used to introduce water for cleaning the brine container 10 and the solid-liquid separation device 11 into the purification tank 18 for purification;

[0032] Liquid is provided in the purification tank 18, the port of the air inlet pipe 181 is immersed below the liquid surface, and the port of the liquid inlet pipe 182 is located above the liquid surface. Specifically, the purification tank 18 mainly absorbs the brine vapor discharged from the solid-liquid separation device 11 and allows it to enter the liquid in the purification tank 18, and the introduced cleaning water is mainly further filtered in the purification tank 18 to reduce the discharge of more organic impurities to the outside.

[0033] like Figure 1 、 2As shown in Figure 3, as a preferred embodiment of the above embodiment, a bubbling device 19 for bubbling and stirring the inside of the braising container 10 is further provided on the outer surface of the braising container 10. The bubbling device 19 includes a pump body provided on the outer wall of the braising container 10. The air inlet end of the pump is located in the braising container 10 and is higher than the liquid level of the brine in the braising container 10. The air outlet end of the bubbling device 19 extends into the braising container 10 and is immersed in the brine. When the pump body is started, the gas in the braising container 10 is circulated and bubbled into the braising container 10, thereby performing stirring treatment and improving the braising effect. The bubbling method for stirring can effectively prevent the eggs from being broken during stirring.

[0034] The specific working principle of the present invention is as follows: first, brine is introduced into the brine container 10, and then steam is introduced from the steam pipe to heat the brine. When the brine reaches a measured temperature, the feed port at the side of the brine container 10 is opened to feed the brine eggs into the brine container 10, and then the feed port is closed and sealed.

[0035] At this time, the pressure pump 15 is started to pressurize the inside of the braising container 10. During the pressurization process, the bubbling device 19 is started to continuously bubble into the braising container 10 to stir it. After the pressure in the braising container 10 reaches the set value, the pressurization is stopped and maintained. Bubbling and stirring are still performed during the maintenance process until the set time is reached, and the braising is completed.

[0036] After the braising is completed, the control valve on the pressure relief pipe 102 is opened to introduce the pressure in the braising container 10 into the accumulator 16 for storage, and then the pressure is released to the discharge pressure by starting the pressure relief pump of the pressure relief pipe 102. When the pressure in the braising container 10 drops to an appropriate pressure, the ball valve 121 is opened to discharge the brine and eggs together into the solid-liquid separation device 11 for separation. During the discharge process, the opening and closing degree of the control valve on the pressure relief pipe 102 is adjusted to maintain a stable discharge pressure in the braising container 10 until the brine and eggs in the braising container 10 are completely discharged.

[0037] The discharged brine and eggs are separated in the solid-liquid separation device 11, and the separated eggs finally fall onto the belt conveyor 13 and are sent out. The brine is cooled by the heat exchanger 17 and then enters the preparation tank 14 for preparation, and is reintroduced into the braising container 10 when waiting for the next braising. Some of the cleaned water and vaporized brine vapor are introduced into the purification tank 18 for purification.
