Description

Technical Field

[0001] This application relates to the field of beer production technology, and more particularly to a heat exchange device for beer production. Background Technology

[0002] In beer production, the mashing process first involves heating the mash formed by mixing malt and water in a mashing tank to activate the enzymes in the malt and promote the decomposition of starch into fermentable sugars. Then, a settling tank is used to separate the wort from the spent grains in the mash after mashing, so as to provide the wort required for the subsequent fermentation process.

[0003] In related technologies, the temperature of wort is typically 70-100℃, while the fermentation temperature of brewer's yeast in the fermentation process is typically 10-25℃. Therefore, by naturally cooling the wort or exchanging heat between the wort and cold water prepared by an ice water generator, the wort temperature can be lowered to 10-25℃ before yeast can be inoculated to start fermentation.

[0004] However, the above method results in low efficiency and high energy consumption when cooling the wort. Utility Model Content

For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components.

Therefore, they should not be construed as limitations on this application.

[0038] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in a sequence other than those illustrated or described herein.

[0039] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or apparatus.

[0040] In beer production, the mashing process first involves heating the mash formed by mixing malt and water in a mashing tank to activate the enzymes in the malt and promote the decomposition of starch into fermentable sugars. Then, a settling tank is used to separate the wort from the spent grains in the mash after mashing, so as to provide the wort required for the subsequent fermentation process.

[0041] In related technologies, the temperature of wort is typically 70-100℃, while the fermentation temperature of brewer's yeast in the fermentation process is typically 10-25℃. Therefore, by naturally cooling the wort or by using an ice water generator to prepare cold water below 0℃ for heat exchange with the wort, the wort temperature can be lowered to 10-25℃ before yeast can be inoculated to start fermentation.

[0042] However, when the wort temperature is lowered by naturally cooling it, the process is time-consuming and the cooling efficiency is low. When the wort temperature is lowered by exchanging heat between cold water prepared by an ice water generator and the wort, the wort temperature is relatively high, so it is usually necessary to prepare cold water below 0°C using an ice water generator before heat exchange can be carried out, resulting in a large energy consumption.

[0043] In view of this, the present application provides a heat exchange device for beer production, which is provided by setting a water supply component and two connected first heat exchange components. The water supply component includes a first water supply component and a second water supply component. The first water temperature in the first water supply component is greater than the second water temperature in the second water supply component, and the first water temperature is less than the wort temperature in the sedimentation tank.

[0044] By connecting one of the two first heat exchangers to the first water supply unit and the other of the two first heat exchangers to the second water supply unit, when the wort comes into contact with one of the two first heat exchangers, water from the first water supply unit is supplied to that one of the two first heat exchangers, allowing the water in the first water supply unit to exchange heat with the wort through the first heat exchanger, thus completing the initial cooling of the wort; when the wort comes into contact with the other of the two first heat exchangers, water from the second water supply unit is supplied to that other one of the two first heat exchangers, allowing the water in the second water supply unit to exchange heat with the wort through the second heat exchanger, thus lowering the temperature of the wort to a preset temperature; wherein the preset temperature is 10-25℃, thereby further lowering the temperature of the wort to the fermentation temperature of the brewer's yeast. Thus, on the one hand, there is no need to wait for the wort to cool naturally, which helps to improve cooling efficiency; on the other hand, since the wort is cooled in two steps by using two first heat exchangers, compared with exchanging heat between the cold water prepared by the ice water generator and the wort, there is no need to lower the temperature of the first water and the second water to the temperature of the ice water, which can save the electrical energy of ice water preparation.

[0045] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0046] See Figure 1 The heat exchange device for beer production provided in this application includes a water supply assembly 100 and two first heat exchange elements 200. The water supply assembly 100 includes a first water supply element 110 and a second water supply element 120. The first water temperature in the first water supply element 110 is greater than the second water temperature in the second water supply element 120, and the first water temperature is less than the wort temperature in the sedimentation tank 810. One of the two first heat exchange elements 200 is connected to the first water supply element 110, and the other of the two first heat exchange elements 200 is connected to the second water supply element 120. The two first heat exchange elements 200 are used to sequentially contact the wort. The water in the first water supply element 110 and the second water supply element 120 is used to sequentially exchange heat with the wort in the corresponding first heat exchange element 200 when the corresponding first heat exchange element 200 contacts the wort, thereby reducing the temperature of the wort to a preset temperature. The preset temperature is 10-25°C.

[0047] Specifically, the first water supply unit 110 and the second water supply unit 120 are used to provide water sources at different temperatures to meet the needs of staged cooling of the wort. The water temperature in the first water supply unit 110 is set to be higher than that in the second water supply unit 120 but lower than the initial temperature of the wort, ensuring that the wort is initially cooled without causing excessive cooling. The second water supply unit 120 is used to further regulate the temperature of the wort to the range required for fermentation. That is, the preset temperature of the wort after cooling is 10-25℃, which is the fermentation temperature of the brewer's yeast, to meet the requirements of subsequent fermentation processes.

[0048] By connecting one of the two first water supply components 110 to the sedimentation tank 810, it is ensured that the high-temperature wort coming out of the sedimentation tank 810 can smoothly enter the heat exchange system, reducing unnecessary transmission losses; the first heat exchange component 200 has a heat exchange function and is used to realize the heat exchange between the water and wort in the first water supply component 110 and the heat exchange between the water and wort in the second water supply component 120.

[0049] It is understood that the first heat exchanger 200 in this application embodiment is a liquid-liquid heat exchanger. In specific implementation, the specific type of liquid-liquid heat exchanger can be set according to the actual situation, and this application embodiment does not limit this. For example, the first heat exchanger 200 can be an immersion heat exchanger. The immersion heat exchanger includes at least one heat exchange element, which is directly immersed in the wort to be cooled. Heat exchange with the wort is achieved through the circulation of the medium inside the heat exchange element. The heat exchange element is a pipe or coil, and the medium is water in the first water supply 110 and the second water supply 120.

[0050] Furthermore, the immersion heat exchanger may include two connection points. The first water supply component 110 may include a first water supply section and a first temperature regulating section. The first water supply section has a first cavity for containing water at a first water temperature, and the first temperature regulating section is used to regulate the temperature of the water in the first cavity to maintain the water at the first water temperature. Correspondingly, the second water supply component 120 may include a second water supply section and a second temperature regulating section. The second water supply section has a second cavity (not shown) for containing water at a second water temperature, and the second temperature regulating section is used to regulate the temperature of the water in the second cavity to maintain the water at the second water temperature.

[0051] Two connection points of an immersion heat exchanger are connected to a first water supply unit. One connection point is used to input water at a first temperature into the heat exchange element, and the other connection point is used to discharge the water after heat exchange to the first water supply unit so that the first temperature control unit can adjust the water temperature to the first temperature and recycle it. Thus, after the sedimentation tank 810 separates the wort and the wort, the wort can flow to the immersion heat exchanger in a similar manner, allowing the heat exchange element of the immersion heat exchanger to be immersed in the wort for contact. Circulating water at the first temperature is supplied to the heat exchange element through the first water supply unit to exchange heat with the wort and initially cool it.

[0052] It should be noted that after the wort is initially cooled, it is pumped to another immersion heat exchanger, so that the heat exchange elements of the immersion heat exchanger are immersed in the wort for contact. The two connection points of the other immersion heat exchanger are connected to the second water supply unit. The specific heat exchange process can be referred to the foregoing content, and will not be repeated in this embodiment.

[0053] For example, the initial temperature of the wort after separation is 99°C; the first water temperature can be set to 70°C-78°C; the temperature of the wort after heat exchange with the water at the first temperature is 85°C-87°C; the second water temperature can be set to 9°C-10°C; the temperature of the wort after heat exchange with the water at the second temperature is 13°C-15°C; and the wort is then transported to... Figure 1 The fermentation tank 820 shown is used to complete the subsequent fermentation process.

[0054] It is understood that the first and second water supply units can be shells or tanks, and the first and second temperature regulating units can be electrically refrigerated modules respectively located inside or outside the first and second water supply units. Compared to the single ice-water cooling method, which requires cooling the water to near 0°C or even lower, generating a large amount of cooling energy and consuming a lot of electricity, the embodiments of this application use a two-step cooling method, which only requires cooling the water to a relatively mild temperature, such as 9.5°C, thereby reducing the energy required for refrigeration and saving the electrical energy for ice-water preparation.

[0055] In summary, the heat exchange device for beer production provided in this application provides that, when the wort comes into contact with one of the two first heat exchange elements 200, water from the first water supply element 110 is supplied to one of the two first heat exchange elements 200, allowing the water in the first water supply element 110 to exchange heat with the wort through the first heat exchange element 200, thus completing the initial cooling of the wort; when the wort comes into contact with the other of the two first heat exchange elements 200, water from the second water supply element 120 is supplied to the other of the two first heat exchange elements 200, allowing the water in the second water supply element 120 to exchange heat with the wort through the second heat exchange element 300, thereby reducing the temperature of the wort to a preset temperature; wherein, the preset temperature is 10-25°C, thereby further reducing the temperature of the wort to the fermentation temperature of the brewer's yeast. Thus, on the one hand, there is no need to wait for the wort to cool naturally, which helps to improve cooling efficiency; on the other hand, since the wort is cooled in two steps by using two first heat exchangers 200, compared with exchanging heat between the cold water prepared by the ice water generator and the wort, there is no need to lower the first water temperature and the second water temperature to the temperature of the ice water, which can save the electrical energy of ice water preparation.

[0056] Continue reading Figure 1In some embodiments, the first heat exchanger 200 has a liquid inlet 210, a liquid outlet 220, a water inlet 230, and a water outlet 240. The liquid inlet 210 and the liquid outlet 220 are connected, and the water inlet 230 and the water outlet 240 are connected. The liquid inlet 210 and the liquid outlet 220 of one of the two first heat exchangers 200 are respectively connected to the liquid inlet 210 of the sedimentation tank 810 and the other liquid inlet 210. The outlet of the first water supply component 110 is connected to the water inlet 230 of one of the two first heat exchangers 200, and the outlet of the second water supply component 120 is connected to the water inlet 230 of the other heat exchanger. The water outlets 240 of the two first heat exchangers 200 are sequentially connected to the inlet of the first water supply component 110.

[0057] This configuration, by optimizing the layout of the heat exchange device, allows the wort to be smoothly transferred between the two first heat exchange elements 200, achieving a continuous and efficient heat exchange process.

[0058] For example, such as Figure 1 As shown, the first water supply component 110 may include a third water supply section 111 and a fourth water supply section 112. The third water supply section 111 contains water at 78°C, and the second water supply component 120 contains water at 9.5°C. Both the third water supply section 111 and the fourth water supply section 112 may be a shell or a tank. That is, 78°C is the first water temperature, and 9.5°C is the second water temperature.

[0059] Furthermore, when the outlet of the first water supply component 110 is sequentially connected to the inlet 230, outlet 240 of one of the two heat exchange components and the inlet of the first water supply component 110, the outlet of the third water supply unit 111 is sequentially connected to the inlet 230, outlet 240 of one of the two heat exchange components and the inlet of the fourth water supply unit 112; when the second water supply component 120 is sequentially connected to the inlet 230, outlet 240 of the other of the two heat exchange components and the inlet of the first water supply component 110, the second water supply component 120 is sequentially connected to the inlet 230, outlet 240 of the other of the two heat exchange components and the inlet of the third water supply unit 111.

[0060] In use, the initial temperature of the wort after separation is 99°C. That is, the initial temperature of the wort flowing in from the inlet 210 of one of the two first heat exchangers 200 is 99°C. After the 99°C wort and 78°C water exchange heat through one of the two first heat exchangers 200, the wort temperature exiting from the outlet 220 and entering the inlet 210 of the other is 87°C. The water temperature exiting from the outlet 240 and entering the fourth water supply section 112 is 97°C. After the 87°C wort and 9.5°C water exchange heat through the other of the two first heat exchangers 200, the wort temperature exiting from the outlet 220 drops to 14°C, which can meet the fermentation temperature of the subsequent brewer's yeast. The water temperature exiting from the outlet 240 and entering the third water supply section 111 is 78°C.

[0061] In this way, after the third water supply unit 111 consumes water at 78°C, it can replenish the third water supply unit 111 with water at 78°C by recovering the heat of the wort; the fourth water supply unit 112 stores water at 97°C by recovering the heat of the wort, so as to achieve a more complete recovery and subsequent utilization of the heat of the wort, thereby reducing heat waste and saving production costs.

[0062] See Figure 2 and Figure 3 In some examples, the heat exchange device for beer production also includes a second heat exchanger 300, with a first water supply 110 connected to the second heat exchanger 300. The second heat exchanger 300 is used to contact the sterilizing liquid of the sterilizer 830. The water in the first water supply 110 is used to exchange heat with the sterilizing liquid in the second heat exchanger 300 when the second heat exchanger 300 contacts the sterilizing liquid, so that the sterilizing liquid rises from a first temperature to a second temperature; wherein the difference between the second temperature and the first temperature is 10-12℃.

[0063] In this way, by heating the sterilizing liquid in the sterilizer 830 with the water in the first water supply unit 110, the heat of the wort can be effectively utilized, reducing the energy required to prepare the high-temperature sterilizing liquid, and at the same time reducing the energy consumption in the beer production workshop.

[0064] For example, the sterilization liquid supplied to the sterilizer 830 in the beer production workshop has a first temperature of 60-62°C. The fourth water supply section 112 in the first water supply component 110 is connected to the second heat exchange component 300. Since the fourth water supply section 112 stores water at 97°C by recovering the heat of the wort, the water in the fourth water supply section 112 can exchange heat with the sterilization liquid in the second heat exchange component 300, so that the temperature of the sterilization liquid is raised to 70-72°C, which meets the actual sterilization temperature requirements.

[0065] The second heat exchanger 300 can be configured as an immersion heat exchanger. The second temperature is 70-72°C after the sterilization liquid is heated. The difference between the second temperature and the first temperature is 10-12°C, for example, it can be 10°C, 11°C or 12°C.

[0066] It should be noted that the number of the second heat exchanger 300 can be set according to the number of beer bottle production lines in the workshop. For example, such as... Figure 3 As shown, there are two second heat exchangers 300, which are used to heat the sterilizers 830 on the two beer bottle production lines respectively.

[0067] See Figure 4 In some embodiments, the second heat exchanger 300 has a first inlet 310, a first outlet 320, a second inlet 330, and a second outlet 340. The first inlet 310 and the first outlet 320 are connected, and the second inlet 330 and the second outlet 340 are connected. The outlet of the first water supply component 110 is connected to the first inlet 310, the first outlet 320 is connected to the inlet of the first water supply component 110, the second inlet 330 is used to connect to the outlet of the sterilizer 830, and the second outlet 340 is used to connect to the inlet of the sterilizer 830.

[0068] Specifically, by connecting the outlet of the first water supply component 110 to the first inlet 310 and the first outlet 320 to the inlet of the first water supply component 110, a water circulation loop is formed, allowing the water after heat exchange to return to the first water supply component 110 for storage. By connecting the second inlet 330 to the outlet of the sterilizer 830 and the second outlet 340 to the inlet of the sterilizer 830, a sterilizing liquid circulation loop is formed, ensuring that the sterilizing liquid can be heated in the second heat exchange component 300 and then returned to the sterilizer 830 for use.

[0069] Furthermore, by establishing a water circulation loop and a disinfectant circulation loop, it is ensured that the water and disinfectant in the first water supply unit 110 can smoothly enter the second heat exchange unit 300 for heat exchange, thus ensuring the stability of heat exchange.

[0070] For example, at least one of the first heat exchanger 200 and the second heat exchanger 300 is a shell-and-tube heat exchanger or a plate heat exchanger.

[0071] Thus, the first heat exchanger 200 has a liquid inlet 210, a liquid outlet 220, a water inlet 230, and a water outlet 240, and the second heat exchanger 300 has a first inlet 310, a first outlet 320, a second inlet 330, and a second outlet 340.

[0072] Specifically, shell-and-tube heat exchangers are suitable for high pressure and high temperature applications, and their robust, durable, and easy-to-maintain structure makes them suitable for long-term use in beer production workshops.

[0073] Plate heat exchangers offer a larger surface area to volume ratio due to their corrugated metal plate design, and their compact structure reduces the space occupied in beer production workshops while achieving efficient heat transfer. In addition, plate heat exchangers typically feature a detachable design, making the internal plates easy to remove and clean, facilitating maintenance.

[0074] See Figure 1 and Figure 4 In specific implementation, a connector 400 is provided at the liquid inlet 210, liquid outlet 220, water inlet 230, and water outlet 240; and / or, a connector 400 is provided at the first inlet 310, first outlet 320, second inlet 330, and second outlet 340; the connector 400 includes a connecting portion 410 and a liquid supply portion 420 provided on the connecting portion 410; the liquid inlet 210, liquid outlet 220, water inlet 230, and water outlet 240 are connected to the corresponding connecting portions 410; and / or, the first inlet 310, first outlet 320, second inlet 330, and second outlet 340 are connected to the corresponding connecting portions 410; the liquid supply portion 420 is used to control the opening and closing of the corresponding connecting portions 410.

[0075] The connecting part 410 serves as a channel for fluid (water, wort, or sterilizing liquid) to enter or leave the first heat exchanger 200 and the second heat exchanger 300, which can reduce the pressure loss of the fluid at the interface and ensure the uniform distribution and stable flow of the fluid; the liquid supply part 420 is used to control the opening and closing state of the connecting part 410, and the liquid supply part 420 can be opened and closed according to actual needs to flexibly adjust the flow of fluid.

[0076] For example, each of the first inlet 310, the first outlet 320, the second inlet 330, and the second outlet 340 is provided with a connector 400. The connecting portion 410 of the connector 400 can be a sanitary thin-walled tube made of stainless steel according to DIN 11850 standards, with a thickness of 0.5mm-2mm. Thus, when connecting the first inlet 310, the first outlet 320, the second inlet 330, and the second outlet 340 to their corresponding connecting portions 410, one end of each of these thin-walled tubes is connected to the first inlet 310, the other end of the thin-walled tube corresponding to the first inlet 310 is connected to the outlet of the first water supply unit 110, the other end of the thin-walled tube corresponding to the first outlet 320 is connected to the inlet of the first water supply unit 110, the other end of the thin-walled tube corresponding to the second inlet 330 is connected to the outlet of the sterilizer 830, and the other end of the thin-walled tube corresponding to the second outlet 340 is connected to the inlet of the sterilizer 830.

[0077] In a specific example, the liquid supply unit 420 includes at least one of a liquid supply pump 421 and a liquid supply valve 422.

[0078] The liquid supply pump 421 is used to provide power to drive the flow of fluid, such as bactericidal liquid, in the second heat exchanger 300 and the corresponding thin-walled tube. The liquid supply valve 422 is used to control the opening and closing of the thin-walled tube and the distribution of fluid, such as water in the first water supply unit 110, to ensure that water flows to the first heat exchanger 200 and the second water supply unit 120 as needed.

[0079] For example, the speed or output power of the liquid supply pump 421 can be adjusted according to actual needs to precisely control the flow rate of the fluid; the valve 522 of the liquid supply valve 422 can be opened or closed as needed to achieve real-time control of the fluid flow.

[0080] See Figures 2 to 4 In some embodiments, the heat exchange device for beer production further includes a condensate collection assembly 500, which includes a first collection element 510 and a first pipe 520. The first collection element 510 is used to collect condensate generated during the saccharification and packaging processes. The first collection element 510 is connected to a first inlet 310 through the first pipe 520. When the second heat exchange element 300 comes into contact with the sterilizing liquid, the first collection element 510 is used to transport the condensate through the first pipe 520 and the first inlet 310 to the second heat exchange element 300, so that the condensate exchanges heat with the sterilizing liquid to raise the sterilizing liquid from a first temperature to a second temperature.

[0081] Thus, the condensate generated in the saccharification and packaging processes is collected and recycled through the first collection unit 510. The temperature of the condensate is usually 90℃-92℃, so as to effectively utilize this waste heat to preheat the sterilization liquid in the sterilizer 830, reduce the need for external heating sources, and reduce energy consumption.

[0082] The first collecting component 510 can be a condensate tank structure, and this application embodiment does not limit this.

[0083] For example, such as Figure 4 As shown, at least one of a pump 521 and a valve 522 can be installed on the first pipe 520. Thus, when heat exchange of the disinfectant solution is required, operators can operate at least one of the pump 521 and valve 522 on the first pipe 520 to open, and operate at least one of the supply pump 421 and supply valve 422 between the first water supply unit 110 and the first inlet 310 to close. This allows heat exchange between the disinfectant solution and the first water supply unit 300 using only the condensate from the first collection unit 510. If the condensate is insufficient, the heat exchange can be switched to water from the first water supply unit 110, ensuring the continuity and stability of the heat exchange process.

[0084] Furthermore, the condensate collection assembly 500 also includes a second collection element 530 and a second pipe 540. The second collection element 530 is connected to the first outlet 320 through the second pipe 540. The second collection element 530 is used to collect the condensate after heat exchange. The second collection element 530 is also used to connect to the bottle washer, sterilizer 830 and evaporative condenser 840 to supply the bottle washer, sterilizer 830 and evaporative condenser 840 with the condensate after heat exchange.

[0085] In this way, the condensate after heat exchange is collected by the second collection element 530 and used for daily water replenishment of the bottle washing machine, sterilizer 830 and evaporative condenser 840, which can reduce water consumption and water waste.

[0086] See Figures 1 to 5 In some embodiments, the heat exchange device for beer production further includes a control unit 600 and multiple temperature detection units 700. The temperature detection units 700 and the liquid supply unit 420 are both electrically connected to the control unit 600. The liquid inlet 210, liquid outlet 220, water inlet 230, and water outlet 240 correspond one-to-one with the temperature detection units 700, so that each temperature detection unit 700 detects the temperature at its corresponding liquid inlet 210, liquid outlet 220, water inlet 230, and water outlet 240. And / or, the first inlet 310, first outlet 320, second inlet 330, and second outlet 340 correspond one-to-one with the temperature detection units 700, so that each temperature detection unit 700 detects the temperature at its corresponding first inlet 310, first outlet 320, second inlet 330, and second outlet 340. The control unit 600 is used to control the opening and closing of the corresponding liquid supply unit 420 based on the temperature detection information from the temperature detection units 700, so that the corresponding connecting part 410 is connected or closed.

[0087] Thus, the temperature detection device 700 detects the temperature of the liquid inlet 210, liquid outlet 220, water inlet 230, water outlet 240, first inlet 310, first outlet 320, second inlet 330, and second outlet 340. When the temperature detection device 700 detects an abnormal temperature, the control device 600 can shut down the corresponding liquid supply section 420 to cut off the fluid flow, reducing the phenomenon of abnormal heat exchange caused by the failure of the first heat exchanger 200 and the second heat exchanger 300. When the temperature detection device 700 detects a normal temperature, the control device 600 can start the corresponding liquid supply section 420 to allow the fluid to flow normally, ensuring normal heat exchange and reducing the need for manual intervention.

[0088] Among them, the control component 600 is a programmable logic controller, and the temperature detection component 700 is a temperature sensor.

[0089] For example, as mentioned above, the wort temperature after heat exchange with water at the first water temperature is 85℃-87℃. When a fault occurs in the connection between the first heat exchanger 200 or the first water supply unit 110 and the first heat exchanger 200, the wort temperature detected by the temperature detection unit 700 will not be within this range. Therefore, the control unit 600 closes the liquid supply section 420 between the liquid outlet 220 and the other first heat exchanger 200 to prevent wort from entering the other first heat exchanger 200. After the operator checks and repairs the problem, the wort is reheated with water at the first water temperature. When the wort temperature detected by the temperature detection unit 700 is 85℃-87℃, the control unit 600 controls the liquid supply section 420 between the liquid outlet 220 and the other first heat exchanger 200 to open, allowing the wort to smoothly enter the other first heat exchanger 200 for heat exchange.

[0090] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
