Description

Technical Field

[0001] The invention relates to the technical field of beverage retorts, and in particular to a beverage retort. Background Art

[0002] The main function of the beverage sterilizer is to kill the microorganisms in canned liquid beverages by providing appropriate temperature and time conditions, thereby ensuring the hygiene safety and long-term stability of the product. This process can not only extend the shelf life of the beverage and improve product quality, but also ensure that the product meets hygiene standards and regulatory requirements and protect consumer health.

[0003] The main defect of the prior art is that when canned beverages are placed in the sterilizer for sterilization, most of the current heating sterilization methods use heat treatment for sterilization, such as high-temperature steam heating. Heat treatment sterilization requires heating the beverage to a certain temperature to achieve the sterilization effect. The canned beverages are carried inside the operating tool. When the high-temperature steam is transmitted to the inside of the sterilizer, the canned beverages at the top will be heated by the steam, and the canned beverages at the bottom have less outer surface exposed to the steam than the canned beverages at the top due to stacking. During the sterilization process, the temperature of the canned beverages at the bottom The temperature of the canned beverages at the top is lower than that of the canned beverages at the top, so there will be a large temperature difference between the canned beverages at the top and the bottom. At the same time, insulation materials are used inside the sterilizer to keep warm during sterilization. Insulation can help maintain a constant temperature and ensure the stability of the temperature during the sterilization process. During the long-term heating and sterilization and cooling and material collection process, the insulation material will become less effective due to the thermal expansion and contraction of heating and cooling, which will cause the temperature inside the sterilizer to fluctuate during sterilization. The insulation will be reduced during subsequent sterilization, which will cause uneven heating of the canned beverages and extend the sterilization time. Secondly, when heating and sterilizing the entire beverage, the beverage needs to be gradually heated up inside the heating pot to make the beverage reach the optimal sterilization temperature. When the beverage enters the sterilization pot from the outside, the temperature of the canned beverage and the temperature inside the sterilization pot are quite different, so it takes a certain amount of time for the beverage to reach the optimal sterilization temperature. In this way, the time required for the entire heating and sterilization will be extended, and there will be a problem of insufficient production capacity. Summary of the invention

[0011] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: First, the steam generated by the steam generator is transmitted to the interior of the sterilization boiler through the steam delivery pipe to heat and sterilize the interior thereof. At the same time, the injected steam will heat the water source in the water tank. When the steam enters the interior of the steam sterilization boiler, the internal steam and pressure of the steam sterilization boiler will increase.

The steam pressure will be transmitted to the interior of the three-way connector through a spring-loaded one-way valve and then to the interior of the pressure tank, squeezing and heating the water source inside the pressure tank, so that the water source is injected into the interior of the water tank through the water injection pipe, so that the water The water level inside the tank rises, and the heated water will reach 90-100°C. The rising water level can reach the inside of the steam sterilization boiler and fill the gap between the loading box and the loading box. The water rising from the water filter port and the filter hole will heat the bottom of the canned beverage inside the loading box. As the steam heats the inside of the steam sterilization boiler, the submerged water source will also be insulated and heated. In this way, during the heating and sterilization process, the rising water will release heat in the insulation stage due to the heated temperature to keep the internal temperature stable. This can avoid drastic temperature fluctuations and ensure the sterilization effect.

[0012] Secondly, water is injected into the water tank through the pressure tank. The rising water source and the continuously spraying steam will further increase the steam pressure inside the sterilization boiler. When the increased steam pressure is transmitted to the inside of the three-way connector through the first delivery pipe, it is not only transmitted to the inside of the pressure tank, but also transmitted to the inside of the second delivery pipe through the second spring-loaded one-way valve. The second delivery pipe is fixed to the top of the preheating boiler and can be transmitted to the inside of the preheating boiler. When the excess steam pressure is transmitted to the inside of the preheating boiler, the beverage will be preheated. This saves energy while the preheated beverage will be heated in advance. The incremental temperature increase reduces the thermal stress caused by the rapid temperature difference in the beverage, which is beneficial to maintaining the taste and texture of the product and avoiding quality reduction.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] The present invention will be further described below in conjunction with the embodiments.

[0018] Example: Refer to Figures 1 to 7 A beverage sterilizing pot comprises a bottom plate 1, a steam generator 5 is fixedly installed at the upper end of the bottom plate 1 near one side edge, the output end of the steam generator 5 is connected with a steam delivery pipe 6, a support pad 8 is fixedly installed on the top of the bottom plate 1, a water tank 7 is fixedly installed on the top of the support pad 8, and a sterilizing boiler assembly 2 is arranged on the top of the water tank 7; The sterilizing boiler assembly 2 includes a preheating boiler 217 fixedly mounted on the upper end surface of the bottom plate 1 and a sterilizing boiler 201 on the top of the water tank 7. The upper end surface of the sterilizing boiler 201 is connected to one end of the steam delivery pipe 6. Sealing slide plates 216 are slidably mounted inside both sides of the sterilizing boiler 201 and the preheating boiler 217. A spring-loaded safety valve 202 is mounted on the upper end of the sterilizing boiler 201. The other end of the spring-loaded safety valve 202 is connected to the first delivery pipe 204. A pressure tank 210 fixed to the bottom plate 1 is fixedly installed between the sterilization boiler 201 and the preheating boiler 217. The interior of the pressure tank 210 is filled with water. A heating and insulation system for maintaining the water temperature is arranged in the pressure tank 210. The heating and insulation system is a prior art and is not shown in the figure. A three-way connector 205 is connected to the top of the pressure tank 210. One end of the three-way connector 205 is connected to one end of the first delivery pipe 204 and a first spring-loaded one-way valve 207 is installed. The bottom end of the pressure tank 210 is connected to the water tank 7 via a water injection pipe 211. A pressure valve 218 is fixedly installed at the connection between the water injection pipe 211 and the water tank 7. A second pressure gauge 209 for monitoring the internal air pressure of the pressure tank 210 and a pressure pump 213 connected to the pressure tank 210 are fixedly installed at the top of the pressure tank 210.

[0019] When the beverage needs to be sterilized, the steam generator 5 is turned on (the working principle of the steam generator 5 is to transport water to the heating element of the steam generator, which is usually an electric heating tube or a combustion furnace, and the water temperature is increased by heating. When the water temperature reaches 100°C (under standard atmospheric pressure), the water begins to be converted into water vapor, that is, the water molecules are heated and become gaseous, and the generated steam is collected and output through the outlet). The steam generated by the steam generator 5 is transmitted to the interior of the sterilization boiler 201 through the steam delivery pipe 6 to heat the interior of the sterilization boiler 201 for heating and sterilization. At the same time, the injected steam will heat the water source in the water tank 7, and the steam When the steam enters the steam sterilizing boiler 201 again, the internal steam and pressure of the steam sterilizing boiler 201 will increase. The increased pressure and steam will be transmitted to the inside of the first delivery pipe 204 through the spring-loaded safety valve 202. The spring-loaded safety valve 202 is provided with a knob. By rotating the knob, the internal spring pressure is adjusted. When the internal pressure of the steam sterilizing boiler 201 reaches the threshold, it is transmitted from the spring-loaded safety valve 202 to the outside. When it is transmitted to the inside of the first delivery pipe 204, the pressure will be transmitted to the inside of the three-way connector 205 through the first spring-loaded one-way valve 207, and then transmitted to the inside of the pressure tank 210, so that the pressure The pressure inside the pressure tank 210 is increased, and the water set inside is heated. There is water inside the pressure tank 210. When the steam pressure pressurizes the inside of the pressure tank 210, the pressure will squeeze the water source inside the pressure tank 210, so that the water source is injected into the water tank 7 through the water injection pipe 211 and the pressure valve 218 (the pressure valve is usually composed of a valve body, a valve seat, a valve core, a spring and other components. When the pressure inside the pipeline or container rises to a set value, the pressure will act on the valve core, overcome the resistance of the spring, and open the valve core, thereby allowing the fluid to flow out through the valve body to reduce the pressure. Once the pressure drops to within the set range, the spring will re-apply pressure. Add force to close the valve core, prevent the fluid from entering or leaving the system, and keep the pressure within a safe range). At this time, the water temperature will reach 90-100°C, and mix with the water source in the water tank 7, so that the water level inside the water tank 7 rises. The rising water level can reach the inside of the steam sterilization boiler 201 and submerge the beverage. As the steam continuously heats the inside of the steam sterilization boiler 201, the submerged water source will also be heated, so that the injected steam heats the top of the beverage, and the rising water source will keep the beverage and the internal temperature warm, so that the internal temperature of the beverage can be uniform during sterilization, thereby performing heating and sterilization.

[0020] Reference Figures 1 to 3The top of the preheating boiler 217 is connected to a second delivery pipe 206, and one end joint of the second delivery pipe 206 and one end of the three-way connector 205 are connected to a second spring-loaded one-way valve 208. The valve opening resistance of the second spring-loaded one-way valve 208 is greater than the valve opening resistance of the first spring-loaded one-way valve 207. A groove 12 is provided at the top of the sterilizing boiler 201, and a fixing box 214 is fixedly installed on one side of the groove 12 close to the spring-loaded safety valve 202. The fixing box 214 is fixedly installed with an electric inlet and exhaust valve 215 on one side of the top in the groove 12. A drain valve 212 is fixedly installed at the bottom of the water tank 7 away from the groove 12. A first pressure gauge 203 for monitoring the internal air pressure of the sterilizing boiler 201 is fixedly installed on the upper end surface of the sterilizing boiler 201.

[0021] By injecting water into the water tank 7 through the pressure tank 210, the water source inside the water tank 7 can rise. The rising water source and the continuously sprayed steam will further increase the steam pressure inside the sterilizing boiler 201. When the increased steam pressure is transmitted to the inside of the three-way connector 205 through the first delivery pipe 204, it is not only transported to the inside of the pressure tank 210, but also transmitted to the inside of the second delivery pipe 206 through the second spring-loaded one-way valve 208. The second delivery pipe 206 is fixed to the top of the preheating boiler 217 and can be transported to the inside of the preheating boiler 217. By placing the beverage that needs to be prepared for heating and sterilization in the preheating boiler 217 in advance, the beverage will be preheated when the excess steam pressure is transmitted to the preheating boiler 217. In this way, while saving energy, the preheated beverage will be heated in advance. When placed in the steam sterilizing boiler 201, it can quickly reach the required sterilization temperature and reduce the time for temperature rise.

[0022] Reference Figures 1 to 5 A mounting block 3 is fixedly installed at the upper end of the bottom plate 1 and at the corresponding position of the pressure tank 210, a conveying track 4 is fixedly installed on the top of the mounting block 3, and the two ends of the conveying track 4 are respectively fixed to the inner bottom ends of the sterilizing boiler 201 and the preheating boiler 217, and at least two loading boxes 9 are slidably installed on the top of the conveying track 4. The pressure tank 210 and the preheating boiler 217 each contain at least one loading box 9, and a loading box 16 is fixedly installed inside the loading box 9. When in the sterilization state, the loading box 9 is arranged inside the sterilizing boiler 201 and the preheating boiler 217, and water filter ports 14 are equidistantly opened inside the two ends of the conveying track 4, and filter holes 13 are equidistantly opened at the inner bottom end of the loading box 9.

[0023] By setting up the conveying track 4, the material box 9 can be transported inside the preheating boiler 217 and the sterilizing boiler 201 through the conveying track 4. The water filter port 14 and the filter hole 13 can increase the water level inside the water tank 7. The rising water can spread to the inside of the material box 9 and the sterilizing boiler 201, and then spread to the gap between the material box 9 and the loading box 16 to keep the canned beverage warm.

[0024] Reference Figures 4 to 5 The inner top of the sterilizing boiler 201 is connected to a first jet pipe 10, and the inner top of the preheating boiler 217 is connected to a second jet pipe 15. The first jet pipe 10 is connected to the steam delivery pipe 6, and the second jet pipe 15 is connected to the second delivery pipe 206.

[0025] By providing the first jet pipe 10 and the second jet pipe 15, the steam transmitted to the sterilizing boiler 201 and the preheating boiler 217 can be evenly sprayed onto the top of the beverage placed in the material loading box 9 for heating.

[0026] Reference Figure 6 to Figure 7 , the inner top ends of the sterilizing boiler 201 and the preheating boiler 217 are both provided with a cleaning assembly 11; The cleaning component 11 includes a fixed plate 1101 fixedly installed at the top of the sterilizing boiler 201 and the preheating boiler 217 and close to the mounting block 3. A support plate 1106 is fixedly installed on the inner wall of the groove 12 on the side away from the fixing box 214, and the support plate 1106 passes through the upper end of the sterilizing boiler 201 and is airtightly fixed thereto. A reciprocating screw rod 1102 is rotatably installed between the fixed plate 1101 and the support plate 1106. A sliding plate 1103 matching the reciprocating screw rod 1102 is sleeved on the outer wall of the fixed plate 1101 close to the reciprocating screw rod 1102. Scrapers 1104 slidably connected to the inner walls of the sterilizing boiler 201 and the preheating boiler 217 are fixedly installed on both sides of the sliding plate 1103.

[0027] By rotating the reciprocating screw 1102, the reciprocating screw 1102 will drive the sliding plate 1103 to slide back and forth on its outer wall, and at the same time drive the scraper 1104 to reciprocate. After the heating and sterilization is completed, the scraper 1104 will clean the inner wall of the preheating boiler 217 to clean the water droplets attached to the inner wall due to steam cooling.

[0028] Reference Figure 6 to Figure 7 The support plate 1106 is located in one side of the groove 12 and is rotatably mounted with a fan 1105, the fan 1105 is arranged on the top of the electric intake and exhaust valve 215, the fan 1105 and the reciprocating screw rod 1102 are connected with a transmission, and the two reciprocating screw rods 1102 are connected with a transmission.

[0029] After the heating and sterilization inside the sterilization boiler 201 is completed, it is necessary to discharge the internal steam pressure to the outside by opening the electric inlet and exhaust valve 215 to prevent people from opening the sealing slide plate 216 and causing steam to drift outward and scald people. The steam pressure discharged to the outside will blow the fan 1105 through the electric inlet and exhaust valve 215 to make it rotate. When the fan 1105 rotates, it will drive the reciprocating screw 1102 to rotate. The reciprocating screw 1102 is driven by a belt to clean up the water droplets attached to the inner walls of the sterilization boiler 201 and the preheating boiler 217.

[0030] The working principle of the present invention is as follows: In the initial stage, canned beverages are placed in at least two loading boxes 9, and then the loading boxes 9 that need to be sterilized and preheated are pushed into the sterilization boiler 201 and the preheating boiler 217 through the conveying track 4, respectively. Water is poured into the water tank 7, and the sealing slides 216 opened on the tops of both sides of the sterilization boiler 201 and the preheating boiler 217 are pushed down and closed to seal the inside of the sterilization boiler 201 and the preheating boiler 217. The steam generator 5 is opened, and the steam generator 5 transmits steam into the inside of the first jet pipe 10 through the steam delivery pipe 6. The first jet pipe 10 will spray steam at the inner top of the sterilization boiler 201, and steam heats the canned beverages placed in the loading boxes 9 placed in the sterilization boiler 201. The temperature of the steam will actively heat the pre-set water inside the water tank 7. Through continuous steam heating, the internal pressure of the sterilizing boiler 201 will gradually increase. The changes in the internal air pressure of the sterilizing boiler 201 can be observed at any time through the first pressure gauge 203. After the internal air pressure of the sterilizing boiler 201 increases to the threshold of the spring-loaded safety valve 202, the spring-loaded safety valve 202 opens the internal valve from the closed state through the gradually increasing pressure. The steam will be transmitted along with the pressure inside the spring-loaded safety valve 202, the first delivery pipeline 204, the first spring-loaded non-return valve 207, and the three-way connector 205. When the steam is transmitted, the pressure of the steam will overcome the valve opening resistance of the first spring-loaded non-return valve 207 and enter the three-way connector. 205, but the opening resistance of the second spring-type one-way valve 208 is not transmitted to the inside of the pressure tank 210, and the pressure tank 210 in the closed state is pressurized. The pressure change inside the pressure tank 210 is observed at any time through the second pressure gauge 209. The pressure tank 210 is provided with water, and the pressure tank 210 is provided with a heating and heat preservation system to heat and keep the water set inside, and maintain the water temperature at 90-100°C, so as to avoid the temperature difference of the water set inside when it is transmitted into the water tank 7, resulting in a temperature drop. The continuous injection of steam will increase the pressure inside the pressure tank 210, and heat it at the same time. As the pressure continues to increase, the water set inside the pressure tank 210 is squeezed, so that the water set inside The water is transmitted to the inside of the water tank 7 through the water injection pipe 211 and the pressure valve 218, so that the water level in the water tank 7 gradually rises. At this time, the water in the water tank 7 will be heated by steam, and the steam is injected into the pressure tank 210 for heating. The heated steam heats the canned beverages from top to bottom. The canned beverages at the top can be heated and sterilized normally, while the canned beverages at the bottom are not heated normally, resulting in a large temperature difference. When the heated water in the pressure tank 210 is injected into the water tank 7, the water in the water tank that has been heated by steam will pass through the filter holes 13 and the water filter port 14 when it rises and flood into the loading box 9. The flooded water will fill the gap between the loading box 9 and the loading box 16. At this time, the canned beverages at the bottom are 50-80°C. According to the law of heat exchange,The heat of the water is transferred to the loading box 16 to heat and keep the canned beverages warm, reducing the temperature difference between the canned beverages at the bottom and the canned beverages at the top. The ejected steam is used to heat and sterilize the canned beverages, while the heated water source and the steam can perform double heating and sterilization and additional insulation on the canned beverages, reducing the temperature difference and shortening the steam sterilization time. The flow direction of steam is: steam generator 5 → sterilizing boiler 201 → spring-loaded safety valve 202 → first delivery pipe 204 → first spring-loaded non-return valve 207 → three-way connector 205 → pressure tank 210. The steam squeezes the pressure tank 210 and is then injected into the water tank 7 through the water injection pipe 211 and the pressure valve 218 to raise the water level. In addition, the water is heated by the continuously injected part of the steam to heat and keep the beverage warm.

[0031] The rising water level and the injected steam will further increase the internal pressure of the sterilizing boiler 201. The increased pressure will accompany the steam when it enters the interior of the three-way connector 205. At this time, the increased gas pressure will not only overcome the valve opening resistance of the first spring-type one-way valve 207, but also overcome the second spring-type one-way valve 208 with a larger valve opening resistance, and enter the interior of the second conveying pipe 206, so that the excess pressure will accompany the steam and enter the interior of the second injection pipe 15 from the interior of the second conveying pipe 206. The second injection pipe 15 will transmit the steam to the interior of the preheating boiler 217 to preheat the canned beverage placed in the preheating boiler 217. In this way, the canned beverage can be heated in advance before entering the interior of the sterilizing boiler 201. After the preheated canned beverage enters the sterilizing boiler 201, the time for heating the canned beverage to the sterilization temperature can be reduced, and at the same time, the wasteful steam discharged outward due to excessive pressure can be saved; The flow direction of steam is steam generator 5 → sterilizing boiler 201 → spring-loaded safety valve 202 → first delivery pipe 204 → first spring-loaded non-return valve 207 → three-way connector 205 → pressure tank 210 → water injection pipe 211 → sterilizing boiler 201 → spring-loaded safety valve 202 → first delivery pipe 204 → first spring-loaded non-return valve 207 → three-way connector 205 → second spring-loaded non-return valve 208 → second delivery pipe 206 → second injection pipe 15 → preheating boiler 217, so that the increased steam pressure can complete the preheating of the beverage inside the preheating boiler 217 on the basis of the pressure causing the water level to rise.

[0032] After sterilization and preheating are completed, the first spring-loaded non-return valve 207 and the second spring-loaded non-return valve 208 are automatically closed, and the electric inlet and exhaust valve 215 is opened to inject external air into the interior of the sterilization boiler 201, and the pressure pump 213 is opened to allow the pressure tank 210 to draw air outward to generate negative pressure, so that suction is generated inside the pressure tank 210, causing the water level in the water tank 7 to drop, and the dropped water returns to the interior of the pressure tank 210 through the water injection pipe 211 and the pressure valve 218. When the internal pressure of the pressure tank 210 is reduced to a certain level, the pressure pump 213 is closed, and the water that has been sucked into the pressure tank 210 is kept stationary by the resistance of the internal valve of the pressure valve 218, and the water level in the water tank 7 returns to the water level before sterilization, and then the electric inlet and exhaust valve 2 15 exhausts the gas outwards to reduce the steam pressure inside the sterilizing boiler 201, and then slowly opens the sealing slide plate 216 to reduce the steam from drifting outwards to avoid scalding personnel. At the same time, the steam discharged first will drive the fan to rotate, and the fan will drive the reciprocating screw 1102 to rotate. The reciprocating screw 1102 will drive the sliding plate 1103 to slide back and forth on its outer wall, and at the same time drive the scraper 1104 to reciprocate. The scraper 1104 will clean the inner wall of the preheating boiler 217 to clean the water droplets attached to the inner wall by steam cooling, so as to avoid the water droplets from adhering to the inner wall for a long time and breeding bacteria. The water droplets will fall into the inside of the water tank 7, and the excess water can be discharged by rotating the drain valve 212. After the sterilization is completed, the water can be replaced to avoid breeding bacteria. Reference Figure 5 The conveying track 4 is configured to be able to push the material-carrying box 9 for circular conveying, which is not completely drawn in the figure, and the conveying track 4 is interspersed inside the sterilizing boiler 201 and the preheating boiler 217 to facilitate pushing; It is assumed that there is at least one material loading box 9 disposed inside the sterilizing boiler 201 and the preheating boiler 217, and preferably 3 to 4 material loading boxes 9, so that before the canned beverages inside the sterilizing boiler 201 are sterilized, other material loading boxes 9 outside the sterilizing boiler 201 and the preheating boiler 217 can be added with canned beverages, so as to avoid the situation where the number of material loading boxes 9 is too small, resulting in the preheating and sterilization time being occupied; After the canned beverages in the sterilizing boiler 201 are sterilized, the sealing slide plates 216 on both sides of the preheating boiler 217 and the sterilizing boiler 201 are opened, and the preheated material loading box 9 in the 217 is pushed out and pushed into the sterilizing boiler 201. In addition, the sterilizing boiler 201 that has been filled with canned beverages and is ready for preheating is pushed into the preheating boiler 217, and the canned beverages in the material loading box 9 pushed out from the sterilizing boiler 201 are taken out; The above process is repeated to periodically update the unpreheated material loading box 9, the preheated material loading box 9 and the sterilized material loading box 9, so that the canned beverage can be repeatedly preheated and sterilized.
