Description

Technical Field

[0001] The utility model relates to the technical field of beer sterilization, in particular to a beer sterilization system. Background Technique

[0002] The existing beer sterilization system plays a role in eliminating yeasts and other impurities remaining in the beer liquid in the beer packaging production line, ensuring the biological stability of the beer, so that the beer can be stored for a long time. The sterilization effect is usually measured by the PU value (i.e., the pasteurization unit, the sterilization effect caused by experiencing 1 minute at 60°C).

[0003] The existing beer sterilization system, such as the energy-saving beer sterilizer disclosed in CN202220165U, includes a sterilizer housing. A conveying chain is provided in the sterilizer housing. The two ends of the conveying chain are respectively a beer inlet and a beer outlet. Along the direction from the beer bottle inlet to the beer bottle outlet at the lower part of the conveying chain, there are respectively a heating zone water tank, a sterilization zone water tank and a cooling zone water tank. At the upper part of the conveying chain, a heating zone spraying device, a sterilization zone spraying device and a cooling zone spraying device are respectively arranged corresponding to the three water tanks; wherein the bottom of the heating zone water tank is connected to the cooling zone spraying device through a pipeline via a first temperature sensor and a first circulation pump, the bottom of the sterilization zone water tank is connected to the sterilization zone spraying device through a pipeline via a second temperature sensor and a second circulation pump, and the bottom of the cooling zone water tank is connected to the heating zone spraying device through a pipeline via a third temperature sensor and a third circulation pump; a heater is also provided in the sterilization zone water tank. The above-mentioned beer sterilizer has three zones, namely a heating zone, a sterilization zone and a cooling zone. It is necessary to separately heat the sterilization zone water tank, the heating zone water tank and the cooling zone water tank, and it is also necessary to control the temperature of the spraying water in the three zones. The control difficulty is large and the energy consumption is large. Secondly, the spraying water is not recycled, the water consumption is extremely large, and the heat carried by the spraying water cannot be effectively utilized, further increasing the waste of energy. Thirdly, after the steam is used as a heat source to heat the heating zone water tank and the cooling zone water tank, the steam condensate is not recycled and reused, further increasing the waste of energy. Content of the Utility Model

[0004] The utility model provides a beer sterilization system, which can greatly reduce energy consumption and water resource consumption, and greatly save the production cost of beer.

[0005] In order to achieve the above technical purposes and reach the above technical effects, the utility model solves the above problems through the following technical solutions:

[0006] A beer sterilization system includes a sterilization chamber and a transmission mechanism passing through the sterilization chamber. Above the transmission mechanism, a heating zone spray head, a high-temperature zone spray head, and a cooling zone spray head are successively arranged along the beer transportation direction; below the transmission mechanism, there are a heating zone water tank, a high-temperature zone water tank, and a cooling zone water tank that are longitudinally corresponding to the heating zone spray head, the high-temperature zone spray head, and the cooling zone spray head in sequence and are used to collect the falling spray water; each water tank is successively equipped with a heating zone spray pump, a high-temperature zone spray pump, and a cooling zone spray pump;

[0007] It also includes a buffer tank, a steam generating device, and a plate heat exchanger. The water output from the buffer tank and the steam output from the steam generating device are heat-exchanged through the plate heat exchanger, and the steam condensate after heat exchange by the plate heat exchanger is sent to the buffer tank;

[0008] The high-temperature zone spray pump extracts the hot water after heat exchange by the plate heat exchanger and the water output from the high-temperature zone water tank and transports it to the high-temperature zone spray head; the cooling zone spray pump extracts the hot water after heat exchange by the plate heat exchanger and the water output from the cooling zone water tank and transports it to the heating zone spray head; the heating zone spray pump extracts the water output from the heating zone water tank and transports it to the cooling zone spray head.

[0009] This system is provided with a control device, and temperature sensors that are respectively matched with the heating zone spray head, the high-temperature zone spray head, and the cooling zone spray head and are used to monitor the water outlet temperature of each spray head are also provided.

[0010] Pneumatic diaphragm valves are respectively arranged on the pipelines where the hot water after heat exchange by the plate heat exchanger leads to the inlets of the high-temperature zone spray pump and the cooling zone spray pump. The control device controls the opening amount of the pneumatic diaphragm valves to adjust the water temperature at the outlets of the high-temperature zone spray pump and the cooling zone spray pump, that is, to adjust the water temperature of the high-temperature zone spray head and the heating zone spray head. The control device of this system collects the temperature data of each temperature sensor, compares it with the preset temperature parameters of the system, and then adjusts the opening amount of the above-mentioned pneumatic diaphragm valves to ensure that the water temperature of each spray head reaches the preset temperature.

[0011] Preferably, the bottom of the high-temperature zone water tank is communicated with the bottom of the buffer tank. The purposes are as follows: 1) During normal production, the water in the buffer tank needs to be continuously replenished to the high-temperature zone water tank and the cooling zone water tank. By communicating with the bottom of the high-temperature zone water tank, it is ensured that the water level in the buffer tank meets the normal production requirements; 2) By connecting the bottom of the high-temperature zone and the buffer tank and replenishing the water in the high-temperature zone water tank into the buffer tank, compared with replenishing cold water from the outside or replenishing the water in the heating zone water tank and the cooling zone water tank, less steam heat is required when the plate heat exchanger is heating up; 3) By connecting the bottom of the high-temperature zone and the hot water buffer tank, the water inside each water tank in the system is balanced and replenished with each other, and the water consumption is also reduced compared with adding cold water from the outside.

[0012] Further, when the circulation pump installed on the pipeline leading from the buffer tank to the inlet of the plate heat exchanger is a fixed-frequency pump, when the amount of hot water extracted is large, even if the buffer tank is connected to the bottom of the high-temperature zone water tank, the water flow rate from the high-temperature zone water tank to the buffer tank is much slower than the water outlet rate of the buffer tank, which will cause the water level in the buffer tank to drop rapidly. At this time, part of the hot water after heat exchange by the plate heat exchanger needs to be refluxed to the buffer tank.

[0013] Preferably, the bottom of the heating zone water tank is connected to the bottom of the cooling zone water tank, which can ensure that the water levels in the heating zone water tank and the cooling zone water tank are the same.

[0014] Preferably, there is water loss during the spray sterilization process of beer, so a water source needs to be supplemented. The water source is generally tap water with a temperature of about 25°C. This water source is respectively transported to the inlets of the high-temperature zone spray pump and the cooling zone spray pump through pipelines, and a pneumatic diaphragm valve is installed on each pipeline. That is, the high-temperature zone spray pump extracts the outlet water of the high-temperature zone water tank, tap water, and the hot water after heat exchange by the plate heat exchanger, and transports it to the high-temperature zone spray head, and the opening of the pneumatic diaphragm valves on the tap water pipeline and the hot water pipeline is controlled by the control device to adjust the water temperature at the outlet of the high-temperature zone spray pump, that is, the spray water temperature of the high-temperature zone spray head connected to this spray pump. Similarly, the cooling zone spray pump also extracts the outlet water of the cooling zone water tank, tap water, and hot water and transports it to the heating zone spray head, and the opening of the pneumatic diaphragm valves on the tap water pipeline and the hot water pipeline is controlled by the control device to adjust the water temperature at the outlet of the cooling zone spray pump, that is, the spray water temperature of the heating zone spray head connected to this spray pump.

[0015] Since the bottoms of the heating zone water tank and the cooling zone water tank are connected, the tap water only needs to be transported to the inlet of the cooling zone spray pump to ensure that the water levels in the heating zone water tank and the cooling zone water tank are the same.

[0016] Preferably, a collection tank for collecting the falling spray water and a filtering device for filtering the spray water are installed on the heating zone water tank, the high-temperature zone water tank, and the cooling zone water tank. The filtering device is specifically a slag removal mesh chain.

[0017] Preferably, the heating zone spray heads, the high-temperature zone spray heads, and the cooling zone spray heads are all multiple arranged along the beer transmission direction; multiple nozzles are installed on each spray head, generally determined according to the width of the sterilization chamber to ensure that all products passing through the sterilization chamber are covered.

[0018] The heating zone spray pumps, the high-temperature zone spray pumps, and the cooling zone spray pumps are all multiple arranged along the beer transmission direction;

[0019] Each high-temperature zone spray pump is connected to each high-temperature zone spray head one by one, and the two are sorted in the same order; each heating zone spray pump is connected to each cooling zone spray head one by one, and the two are sorted in the opposite order; each cooling zone spray pump is connected to each heating zone spray head one by one, and the two are sorted in the opposite order. With such a setting, the sterilization temperature of the beer can be more accurately controlled, and the sterilization effect is better.

[0020] Further preferably, the number of high-temperature zone spray pumps is 4, and the number of heating zone spray pumps and cooling zone spray pumps is 3 each, namely high-temperature zone spray pump 1, high-temperature zone spray pump 2, high-temperature zone spray pump 3, high-temperature zone spray pump 4; heating zone spray pump 1, heating zone spray pump 2, heating zone spray pump 3; cooling zone spray pump 1, cooling zone spray pump 2, cooling zone spray pump 3.

[0021] The number of high-temperature zone spray heads is 4, and the number of heating zone spray heads and cooling zone spray heads is 3 each, namely high-temperature zone spray head 1, high-temperature zone spray head 2, high-temperature zone spray head 3, high-temperature zone spray head 4; heating zone spray head 1, heating zone spray head 2, heating zone spray head 3; cooling zone spray head 1, cooling zone spray head 2, cooling zone spray head 3.

[0022] The outlet of high-temperature zone spray pump 1 is connected to high-temperature zone spray head 1, the outlet of high-temperature zone spray pump 2 is connected to high-temperature zone spray head 2, the outlet of high-temperature zone spray pump 3 is connected to high-temperature zone spray head 3, and the outlet of high-temperature zone spray pump 4 is connected to high-temperature zone spray head 4. The outlet of heating zone spray pump 1 is connected to cooling zone spray head 3, the outlet of heating zone spray pump 2 is connected to cooling zone spray head 2, and the outlet of heating zone spray pump 3 is connected to cooling zone spray head 1. The outlet of cooling zone spray pump 1 is connected to heating zone spray head 3, the outlet of cooling zone spray pump 2 is connected to heating zone spray head 2, and the outlet of cooling zone spray pump 3 is connected to heating zone spray head 1.

[0023] After the beer is filled and capped by the filling machine, it is transported by the conveyor belt into the beer sterilization system of the present invention for sterilization. The beer is successively transported to the lower parts of the heating zone spray head, the high-temperature zone spray head and the cooling zone spray head by the transmission mechanism, and is sprayed by the spray water at a specific temperature in sequence to achieve the sterilization effect. Specifically:

[0024] 1) The beer is transported by the transmission mechanism to the lower part of the heating zone spray head. The water discharged from the cooling zone water tank and the hot water and tap water heated by the plate heat exchanger are mixed and then sent to the heating zone spray head by the cooling zone spray pump to spray the beer. The temperature sensor arranged in combination with the heating zone spray head monitors the water temperature of the heating zone spray water. The water temperature signal is transmitted to the control device, and the opening degrees of the two pneumatic diaphragm valves at the inlet of the cooling zone spray pump are adjusted according to the set temperature, so as to adjust the water temperature of the heating zone spray water. At the same time, the spray water sprinkled by the heating zone spray head is collected by the heating zone water tank.

[0025] 2) The beer is further transported by the transmission mechanism to the bottom of the high temperature zone spray head. The water from the high temperature zone water tank, the hot water after heat exchange in the plate heat exchanger and the tap water are mixed and transported to the high temperature zone spray head by the high temperature zone spray pump to spray and sterilize the beer. The temperature sensor matched with the high temperature zone spray head monitors the water temperature of the high temperature zone spray water. The water temperature signal is transmitted to the control device, and the opening of the two pneumatic diaphragm valves at the inlet of the high temperature zone spray pump is adjusted according to the set temperature, thereby adjusting the temperature of the high temperature zone spray water. The spray water sprinkled by the high temperature zone spray head can be repeatedly used after being collected by the high temperature zone water tank.

[0026] 3) The beer is further transported by the transmission mechanism to the bottom of the cooling zone spray head, and the water from the heating zone water tank is transported to the cooling zone spray head through the heating zone spray pump to spray the beer. That is, the spray water from the heating zone spray head is collected by the heating zone water tank and immediately transported to the cooling zone spray head to cool and sterilize the beer. The temperature sensor matched with the cooling zone spray head monitors the water temperature of the cooling zone spray water and transmits it to the display screen through the control device. Since the control device adjusts the water outlet temperature of the heating zone spray head, the spray water there is heat exchanged with the beer and then transported to the cooling zone spray head to cool the beer at just the right temperature, and no additional adjustment is required.

[0027] The advantages and effects of the utility model are:

[0028] 1) The spray water sprayed by the sprinkler head in the heating zone is received by the water tank in the heating zone after it falls. Similarly, the spray water in the high temperature zone is received by the water tank in the high temperature zone, and the spray water in the cooling zone is received by the water tank in the cooling zone. In this way, water can be recycled and reused, which not only saves water resources, but more importantly, the heat carried by the spray water can also be recovered on-site to the water tank, and then immediately transported to the sprinkler head by the spray pump to continue spraying and sterilizing, which greatly saves heat.

[0029] 2) The spray water collected in the water tank in the heating zone is the cold water after heat exchange with the beer. Generally, the beer temperature at the inlet of the heating zone is 4-6°C. The spray water in the heating zone and the beer exchange heat with each other. After the beer is heated, the cooled spray water passes through the collection tank and the filtering device (specifically, it can be a slag removal network chain) on the water tank in the heating zone. It enters the water tank in the heating zone and is pumped to the spray head in the cooling zone by the spray pump in the heating zone for cooling. No additional heat source is required for heating, which further reduces the steam consumption.

[0030] 3) The hot water after the water outlet of the buffer tank is heated by the plate heat exchanger (generally heated to 85°C) is transported by the spray pumps to the high-temperature zone spray heads and the heating zone spray heads according to the outlet temperature requirements of the high-temperature zone spray pump and the cooling zone spray pump. Since products continuously enter the sterilizer during the production process, hot water needs to be continuously output from the buffer tank to the outlets of the high-temperature zone and the cooling zone spray pumps to achieve the effect of product heating and sterilization. The steam temperature used by the plate heat exchanger for heating the buffer tank is generally around 150°C, and the temperature of the steam condensate after passing through the plate heat exchanger is generally above 90°C. By recycling and transporting the steam condensate to the buffer tank to directly supplement 90°C hot water to the buffer tank, steam consumption and water consumption can be greatly saved.

[0031] 4) After the beer goes through the filling and capping procedures, the initial temperature of the beer cans or bottles entering this system is 4 - 6°C. The sterilization temperature control process of this system is: relatively high temperature --- high temperature --- low temperature. The water outlet of the cooling zone water tank at the end of this system is mixed with hot water and then transported to the heating zone spray heads at the beginning of the system for spraying. The temperature of the falling spray water slightly decreases after contacting the beer cans and is collected by the heating zone water tank and then transported to the cooling zone spray heads, and its temperature just meets the water temperature requirements of the cooling zone spray water. In addition, after the beer cans (beer bottles) are sprayed with the high-temperature zone spray water, the temperature rises significantly. After continuing to be transported to the cooling zone and exchanging heat with the cooling zone spray water, the beer cans are cooled, while the water temperature of the cooling zone spray water rises and is collected by the cooling zone water tank, and is transported by the cooling zone spray pump to the heating zone spray heads to heat the beer cans, realizing the internal recycling and utilization of heat energy from the high-temperature zone to the cooling zone. The hot water after being heated by the plate heat exchanger is used as a supplement when the water temperature collected by the cooling zone water tank is insufficient to ensure the temperature requirements for transporting to the heating zone spray heads, greatly saving energy.

[0036] The present utility model will be further described below in conjunction with embodiments, but the present utility model is not limited to these embodiments.

[0037] The beer sterilization system described in this embodiment is as shown in the attached Figure 1 、 2 figure.

[0038] A beer sterilization system includes a sterilization chamber (10) and a transmission mechanism (11) passing through the sterilization chamber (10). Above the transmission mechanism (11), a heating zone spray head (7), a high-temperature zone spray head (8), and a cooling zone spray head (9) are sequentially arranged along the beer transportation direction; below the transmission mechanism (11), there are a heating zone water tank (1), a high-temperature zone water tank (2), and a cooling zone water tank (3) that are longitudinally corresponding to the heating zone spray head (7), the high-temperature zone spray head (8), and the cooling zone spray head (9) in sequence and are used for collecting the falling spray water; each water tank is sequentially equipped with a heating zone spray pump (4), a high-temperature zone spray pump (5), and a cooling zone spray pump (6);

[0039] It also includes a buffer tank (12), a steam generating device (13), and a plate heat exchanger (14). The water output from the buffer tank (12) and the steam output from the steam generating device (13) are heat-exchanged through the plate heat exchanger (14), and the steam condensate after heat exchange by the plate heat exchanger (14) is sent to the buffer tank (12);

[0040] The high-temperature zone spray pump (5) extracts the hot water after heat exchange by the plate heat exchanger (14) and the water output from the high-temperature zone water tank (2), and conveys it to the high-temperature zone spray head (8); the cooling zone spray pump (6) extracts the hot water after heat exchange by the plate heat exchanger (14) and the water output from the cooling zone water tank (3), and conveys it to the heating zone spray head (7); the heating zone spray pump (4) extracts the water output from the heating zone water tank (1) and conveys it to the cooling zone spray head (9).

[0041] The above-mentioned transmission mechanism (11) can be divided into upper and lower layers, and each layer is a plastic transmission chain net.

[0042] This system is also equipped with a control device. The heating zone spray head (7), the high-temperature zone spray head (8), and the cooling zone spray head (9) are all equipped with temperature sensors for monitoring the water temperature of the spray water of each spray head.

[0043] On the pipelines where the hot water after heat exchange by the plate heat exchanger (14) leads to the inlets of the high-temperature zone spray pump (5) and the cooling zone spray pump (6) respectively, pneumatic diaphragm valves are provided. The control device collects the water temperature data of the water output from the heating zone spray head (7) and the high-temperature zone spray head (8), and compares it with the preset temperature parameters of the system, and then adjusts the opening of the pneumatic diaphragm valves at the inlets of the cooling zone spray pump (6) and the high-temperature zone spray pump (5) respectively to ensure that the water temperatures of the heating zone spray head (7) and the high-temperature zone spray head (8) reach the preset temperature.

[0044] If the circulation pump set on the pipeline leading from the buffer tank (12) to the inlet of the plate heat exchanger (14) is a fixed-frequency pump, when the amount of water extracted by the circulation pump is large, even if the buffer tank (12) and the bottom of the high-temperature zone water tank (2) are connected, the water flow from the high-temperature zone water tank (2) to the buffer tank (12) is much slower than the water output speed of the buffer tank (12), which will cause the water level of the buffer tank (12) to drop rapidly. At this time, part of the hot water after heat exchange by the plate heat exchanger (14) needs to be refluxed to the buffer tank (12).

Similarly, the cooling zone spray pump (6) also extracts the water discharged from the cooling zone water tank (3), tap water, and hot water and transports them to the heating zone spray heads (7), and adjusts the water temperature at the outlet of the cooling zone spray pump (6), that is, the spray water temperature of the heating zone spray heads (7) connected to this spray pump, by controlling the opening amount of the pneumatic diaphragm valves on the tap water pipeline and the hot water pipeline through the control device.
