Description

Technical Field

[0001] This invention belongs to the field of dairy product processing and fermentation technology, and particularly relates to an integrated device for sterilizing and fermenting dairy products. Background Technology

[0002] As people pay more attention to food hygiene, quality, and health, many people have higher and higher requirements for dairy products. During the fermentation process of dairy products, many factors will affect the quality of dairy products, including the temperature, humidity, fermentation time, and air quality. While the temperature, humidity, and fermentation time can be accurately controlled and adjusted by humans, the air quality used during fermentation is difficult to control accurately. There are many bacteria and impurities in the air that are detrimental to the fermentation process. If the processing is not precise enough, it can easily have a significant impact on the quality of the fermented dairy products.

[0003] The existing dairy product fermentation and sterilization are mostly carried out separately. That is, before fermentation, the fermentation equipment and the surrounding air are sterilized by the corresponding sterilization equipment. However, the above method has the following problems when running: (1) When heating and sterilizing dairy products, the steam itself and during the transmission process will be mixed with some dust and impurities. When it comes into contact with the fermentation equipment, it is easy to cause pollution or damage to the fermentation equipment.

[0004] (2) During the fermentation process of dairy products, it is necessary to ventilate them regularly to increase the oxygen required for the respiration and metabolism of microorganisms during fermentation. However, the existing ventilation method is simply to introduce outside air into the fermentation equipment. Dust and impurities in the air can easily have other effects on the fermentation of dairy products.

[0005] (3) When the existing equipment ventilates the fermentation of dairy products, there is a lack of connection between the two and they operate independently, resulting in less connection between the various structures of the equipment, which is not conducive to maximizing the efficiency of the equipment operation.

[0006] Therefore, in view of the above-mentioned problems, this technical solution proposes an integrated device for sterilization and fermentation of dairy products. Summary of the Invention

[0007] The purpose of this invention is to provide an integrated sterilization and fermentation device for dairy products, which aims to solve the following problems.

[0008] The present invention is implemented as follows: an integrated device for sterilizing and fermenting dairy products includes: a fermentation tank, a fermentation chamber is provided inside the fermentation tank, and a dairy product input channel and a dairy product output channel are respectively connected to the top two sides of the fermentation chamber. The dairy products to be fermented are input into the fermentation chamber through the dairy product input channel for fermentation, and the fermented dairy products are output through the dairy product output channel, thus forming an automated in-out-out transmission and fermentation mode.

[0009] A steam jet pump is connected to one side of the dairy product input channel. A connecting pipe connects the upper exterior of the dairy product input channel and the dairy product output channel. The steam jet pump is used to input high-temperature steam into the dairy product input channel. Before dairy products are input, the high-temperature steam is controlled to flow along the dairy product input channel, fermentation chamber, dairy product output channel, and connecting pipe to perform high-temperature sterilization pretreatment on the upper pipes and tanks. An air dust collector is connected to one side of the steam jet pump. The air dust collector is used to remove dust and purify the air to ensure the dust-free nature of the air input into the steam jet pump.

[0010] The steam heating chamber is located outside the fermentation chamber. A heat-conducting layer is provided on the side of the steam heating chamber facing the fermentation chamber. The top side of the steam heating chamber is connected to the output end of the steam jet pump through a transmission pipe, and the other side of the top of the steam heating chamber is connected to a return transmission pipe. High-temperature steam from the steam jet pump is input into the steam heating chamber, and then the dairy products placed inside the fermentation chamber are sterilized by high-temperature heating under the heat conduction of the heat-conducting layer. The high-temperature steam in the steam heating chamber is output along the return transmission pipe.

[0011] The circulating air intake chamber is located inside the fermentation tank outside the steam heating chamber. An automatic air intake component is installed inside the circulating air intake chamber. An air storage chamber is connected to the outside of the circulating air intake chamber. The air storage chamber stores purified air. One side of the automatic air intake component is connected to the inside of the fermentation chamber to periodically deliver purified clean air into the fermentation chamber, ensuring aseptic ventilation and oxygenation of the dairy products inside the fermentation chamber. One side of the top of the air storage chamber is connected to the return transmission pipe. When the steam heated by the steam heating chamber flows through the fermentation chamber, it flows back directly to the air storage chamber when it is output along the return transmission pipe. Since the steam has been pre-purified, its temperature decreases after flowing in the steam heating chamber, and it still has the ability to be used aseptically again. Therefore, it is transferred to the air storage chamber to give it a secondary use function.

[0012] The integrated stirring and ventilation mechanism is used to periodically ventilate and stir the dairy products inside the fermentation chamber to improve the respiratory and metabolic rate of microorganisms in the dairy products. The integrated stirring and ventilation mechanism includes a stirring component that is rotatably installed inside the fermentation chamber. The lower side of the stirring component is rotatably connected to the automatic air intake components inside the two circulating air intake chambers. That is, while the stirring component is running, it drives the automatic air intake components on both sides to circulate and rise, driving the clean air inside the circulating air intake chamber to be transported into the fermentation chamber, oxygenating the dairy products inside the fermentation chamber and stirring them in conjunction with the stirring component to improve the fermentation efficiency.

[0013] The present invention provides an integrated sterilization and fermentation device for dairy products. The air is purified by an air dust collector and then transferred to a steam jet pump to mix with steam, thereby increasing the steam feed rate and the steam input speed. Before the dairy products are fed in, the inner wall of the steam is sterilized at high temperature by passing through the dairy product input channel, fermentation chamber, dairy product output channel and connecting pipe, thereby reducing the impact of the device body on bacterial contamination during the subsequent fermentation of dairy products.

[0014] Steam is introduced into the steam heating chamber to heat the fermentation chamber, and then the dairy products are sterilized by high-temperature heating, which further improves the sterilization degree of dairy product fermentation. Then, the heated steam is transferred to the air storage chamber. With the action of the automatic air intake component and the cooperation of the stirring component, the cooled gas is introduced into the fermentation chamber to stir the dairy products, ventilate, and increase oxygen, while ensuring the sterility of the input gas, so as to fully improve the gas utilization rate and increase the fermentation efficiency.

[0015] By setting up a set of servo motors to drive the stirring assembly and the automatic air intake assembly to operate synchronously, and by utilizing the transmission relationship between the various structures, the utilization rate of kinetic energy of this device is greatly improved, and the fermentation production and processing costs are reduced.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0027] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0028] like Figure 1 The diagram shown is a structural diagram of an integrated sterilization and fermentation device for dairy products provided in an embodiment of the present invention. It includes: a fermentation tank 10, a fermentation chamber inside the fermentation tank 10, and a dairy product input channel 14 and a dairy product output channel 15 respectively connected to the top two sides of the fermentation chamber. The dairy products to be fermented are input into the fermentation chamber through the dairy product input channel 14 for fermentation, and the fermented dairy products are output through the dairy product output channel 15, thus forming an automated in-out-out transmission fermentation mode.

[0029] A steam jet pump 13 is connected to one side of the dairy product input channel 14. A connecting pipe 36 connects the upper exterior of the dairy product input channel 14 and the dairy product output channel 15. The steam jet pump 13 is used to input high-temperature steam into the dairy product input channel 14. Before dairy products are input, the high-temperature steam is controlled to flow along the dairy product input channel 14, the fermentation chamber, the dairy product output channel 15, and the connecting pipe 36 to perform high-temperature sterilization pretreatment on the upper pipes and tanks. An air dust collector 12 is connected to one side of the steam jet pump 13. The air dust collector 12 is used to remove dust and purify the air to ensure the dust-free nature of the air input into the steam jet pump 13.

[0030] A steam heating chamber 19 is located outside the fermentation chamber. A heat-conducting layer 34 is provided on the side of the steam heating chamber facing the fermentation chamber. The top side of the steam heating chamber 19 is connected to the output end of the steam jet pump 13 through a transmission pipe. The other side of the top of the steam heating chamber 19 is connected to a return transmission pipe 35. High-temperature steam from the steam jet pump 13 is input into the steam heating chamber 19. Then, under the heat conduction of the heat-conducting layer 34, the dairy products placed inside the fermentation chamber are sterilized by high-temperature heating. The high-temperature steam in the steam heating chamber 19 is output along the return transmission pipe 35.

[0031] The circulating air intake chamber 20 is located inside the fermentation tank 10 outside the steam heating chamber 19, and an automatic air intake component is installed inside the circulating air intake chamber 20. An air storage chamber 33 is connected to the outside of the circulating air intake chamber 20. The air storage chamber 33 stores purified air. One side of the automatic air intake component is connected to the inside of the fermentation chamber, and is used to periodically deliver purified clean air into the fermentation chamber to ensure aseptic ventilation and oxygenation of the dairy products inside the fermentation chamber. One side of the top of the air storage chamber 33 is connected to the return transmission pipe 35. When the steam heated by the steam heating chamber 19 flows into the fermentation chamber, it flows back directly into the air storage chamber 33 when it is output along the return transmission pipe 35. Since the steam has been pre-purified, its temperature decreases after flowing in the steam heating chamber 19, and it still has the ability to be used aseptically again. Therefore, it is transferred to the air storage chamber 33 to give it a secondary use function.

[0032] The integrated stirring and ventilation mechanism is used to periodically ventilate and stir the dairy products inside the fermentation chamber to improve the respiratory and metabolic rate of microorganisms in the dairy products. The integrated stirring and ventilation mechanism includes a stirring component 17 that is rotatably installed inside the fermentation chamber. The lower side of the stirring component 17 is rotatably connected to the automatic air intake components inside the two circulating air intake chambers 20. That is, while the stirring component 17 is running, it drives the automatic air intake components on both sides to circulate and rise and fall, driving the clean air inside the circulating air intake chamber 20 to be transported into the fermentation chamber, oxygenating the dairy products inside the fermentation chamber and stirring them in conjunction with the stirring component 17 to improve the fermentation efficiency.

[0033] In this embodiment of the invention, a steam exhaust port is provided on one side wall of the dairy product output channel 15 to discharge the steam flowing along the dairy product input channel 14, fermentation chamber, dairy product output channel 15, and connecting pipe 36. Control valves are provided at the connection points of the connecting pipe 36, return transmission pipe 35, transmission pipe, air dust collector 12, and steam jet pump 13 to accurately control the flow of each gas between them. At the same time, an overflow port is provided on one side of the top of the heat-conducting layer 34. When the gas output from the return transmission pipe 35 cannot be stored in the air storage chamber 33, it can be discharged to the outside through the overflow port. A control valve is also provided on the overflow port. A set of one-way exhaust holes 16 is provided in the middle of the top of the fermentation chamber to release the gas input into the fermentation chamber to the outside and prevent external air from directly entering the fermentation chamber along the one-way exhaust holes 16.

[0034] The two air storage chambers 33 are in a state of mutual communication. When air is input into the air storage chamber 33 through the return transmission pipe 35 on one side, it flows on its own to fill the two air storage chambers 33.

[0035] It should be noted that for fermented dairy products, the heating and sterilization temperature is generally set at around 100°C in the fermentation tank, and the sterilization time is around 30 minutes at the air inlet. A set of tank bases 11 are fixedly installed at the bottom of the fermentation tank 10. The air dust collector 12 and the steam jet pump 13 are also installed on the tank bases 11 through brackets and other structures (not shown in the figure) to ensure the stable installation and operation of each structure.

[0036] In one example of the present invention, such as Figure 2 , Figure 4As shown, the air dust collector 12 includes an air input channel 120. The output end of the air input channel 120 is connected to a horizontally placed conical contraction tube 121. The end of the contraction tube 121 is connected to a throat 122. On the side of the throat 122 away from the contraction tube 121, multiple equally spaced water inlet pipes 123 are connected in a ring shape. The ends of the water inlet pipes 123 are all connected to a water inlet tray 124. Simultaneously, a diffuser 125 is connected to the middle of the side of the throat 122 away from the contraction tube 121. A water inlet is provided on one side of the water inlet tray 124. High-pressure, high-speed water is supplied to the inside of the water inlet tray 124 through the water inlet, and then, under the transmission of the water inlet pipes 123, it enters the throat 122 at high speed. At the same time, external air also enters the throat at high speed through the air input channel 120. Inside 122, high-speed air collides with high-speed airflow to form mist droplets. At this time, dust in the air collides with the mist droplets to form large particles that are settled. A cyclone separator 126 is connected to the rear of the diffuser 125, and a solid-gas separation pipe 127 is connected to the rear of the cyclone separator 126. A purified gas output pipe 128 is connected to the top of the solid-gas separation pipe 127, and a dust output pipe 129 is connected to the bottom. The settled large particles are transferred to the cyclone separator 126 and the solid-gas separation pipe 127 for separation after passing through the diffuser 125. At the same time, the gas is simultaneously dusted and purified. Large particulate impurities are output along the dust output pipe 129 at the bottom of the solid-gas separation pipe 127, and purified gas is output along the purified gas output pipe 128 at the top of the solid-gas separation pipe 127, thereby achieving dust removal treatment of the air.

[0037] A water inlet 1299 is provided on one side of the throat pipe 122 corresponding to the position of the water inlet pipe 123. The water inlet 1299 is connected to the end of the water inlet pipe 123, so as to realize the function of water inlet pipe 123 conveying water into the throat pipe 122.

[0038] As a preferred embodiment of the present invention, such as Figure 3As shown, the steam jet pump 13 includes a purified gas input pipe 131 connected to the end of the purified gas output pipe 128. A mixing chamber 132 is connected to the top of the purified gas input pipe 131. A steam inlet 134 is connected to the outside of the mixing chamber 132, delivering steam towards the interior of the mixing chamber 132. Simultaneously, a nozzle 130 is connected to the inner end of the steam inlet 134, allowing steam to be ejected at high speed towards the interior of the mixing chamber 132 after passing through the nozzle 130. A funnel-shaped nozzle is connected to the end of the mixing chamber 132 furthest from the steam inlet 134. The jet pipe 133 is connected to 14 at its end. The dust-removed air input through the purified gas input pipe 131 is mixed with high-temperature steam in the mixing chamber 132. After the steam enters the nozzle, it is ejected at high speed, generating low pressure, which draws in the gas and mixes it in the mixing chamber 132. After being expanded through the jet pipe 133, the kinetic energy is converted into pressure energy and then transported towards 14. By properly mixing the steam and air, the gas feed rate is increased, while ensuring the high temperature and sterility of the input steam, thereby realizing the subsequent sterilization, ventilation and oxygen supply functions.

[0039] As a preferred embodiment of the present invention, such as Figure 1 , Figure 7 , Figure 9 As shown, it represents a partial structure of the integrated stirring and ventilation mechanism. The stirring component includes a servo motor 18 fixed in the middle of the bottom of the fermentation tank 10. The output end of the servo motor 18 is connected to an output shaft 21. The top end of the output shaft 21 extends into the fermentation chamber and is connected to a stirring shaft 22 via a connecting shaft 28. Multiple stirring blades are evenly installed on the outer circumferential wall of the stirring shaft 22. When the servo motor 18 is started, it drives the output shaft 21 to rotate. With the connection of the connecting shaft 28, the stirring blades on the stirring shaft 22 stir the dairy products inside the fermentation chamber.

[0040] As a preferred embodiment of the present invention, such as Figure 1 , Figure 5 , Figure 6 , Figure 8 , Figure 9As shown, the automatic intake assembly includes a lead screw 25 rotatably disposed in the middle of the circulating intake chamber 20. A nut 26 is threaded onto the lead screw 25, and a guide device is provided on the nut 26 to limit its rotation. The top end of the lead screw 25 is rotatably connected to the top wall of the circulating intake chamber 20 via a bearing, and the bottom end of the lead screw 25 moves through the bottom of the circulating intake chamber 20 and is connected to a connecting post 24. The bottom end of the connecting post 24 extends to the height of the output shaft 21. The output shaft 21 and the connecting post 24 are connected by a transmission belt 23, i.e., servo motor. While the output shaft 21 of the drive unit 18 rotates, it synchronously drives the lead screw 25 in the circulating air intake chamber 20 to rotate under the connection of the transmission belt 23. This drives the nut 26 to move up and down cyclically along the lead screw 25. A sealing buffer layer is installed on the outer circumferential wall of the nut 26 to keep the nut 26 in close contact with the inner wall of the circulating air intake chamber 20 during its up and down movement. An air inlet 30 is opened on the bottom side of the circulating air intake chamber 20 facing the interior of the air storage chamber 33. A swinging device is provided on the air inlet 30 located on the inner side of the circulating air intake chamber 20. A magnetic baffle 29 is provided with a magnetic ring on the side of the magnetic baffle 29 facing the air inlet 30. A magnetic ring is provided on the outer wall of the air inlet 30 corresponding to the magnetic ring. The magnetic ring and the magnetic ring are magnetically connected. When the nut 26 moves upward, an upward attraction is generated, which then drives the magnetic baffle 29 to swing, opening the air inlet 30. Then, the gas inside the air storage chamber 33 is transferred to the circulating air intake chamber 20 and gathers inside the circulating air intake chamber 20 below the nut 26. The bottom of the circulating air intake chamber 20 facing the fermentation chamber is connected to a steam-absorbing channel. The hot chamber 19 extends to the exhaust pipe 31 inside the fermentation chamber. A gas one-way valve 32 is installed inside the exhaust pipe 31. The gas one-way valve 32 is used to prevent the dairy products and gas inside the fermentation chamber from flowing back along the exhaust pipe 31. When the nut 26 is lowered, the nut 26 generates downward pressure, which squeezes the gas accumulated inside the circulating air intake chamber 20. At this time, the gas one-way valve 32 is opened by force, transferring the gas towards the inside of the fermentation chamber. This realizes the function of automatically drawing in gas inside the circulating air intake chamber 20 and transferring it towards the inside of the fermentation chamber.

[0041] To maintain the sealing of the upper and lower sides of the nut 26 after the lead screw 25 is threadedly connected to the nut 26, a sealing buffer plate 27 is installed in the middle of the lower side of the nut 26. The lead screw 25 moves through the sealing buffer plate 27. A buffer sealing ring is provided on the inner side of the sealing buffer plate 27 to keep the lead screw 25 and the sealing buffer plate 27 moving smoothly while sealing the upper and lower sides of the nut 26. At the same time, a buffer sealing ring is also provided at the movable connection between the connecting column 24 and the bottom of the circulating air intake chamber 20.

[0042] The above embodiments of the present invention provide an integrated sterilization and fermentation device for dairy products. Upon startup, the air dust collector 12 and steam jet pump 13 are activated. External air, after being treated by the air dust collector 12, is transferred to the steam jet pump 13. Then, the high-temperature steam inside the steam jet pump 13 mixes with the dust-treated air and is injected into the dairy product input channel 14. This process proceeds in two states: First, before placing the dairy products into the fermentation chamber, the dairy product input channel 14, fermentation chamber, and dairy product output channel 15 are pre-sterilized at high temperature. This is achieved by the high-temperature steam from the steam jet pump 13 flowing along the dairy product input channel 14, fermentation chamber, dairy product output channel 15, and connecting pipe 36, sterilizing the interior of the dairy products to ensure their sterility upon entry. Second, during dairy product fermentation, the dairy products are input into the fermentation chamber through the dairy product input channel 14, and then steam... High-temperature steam from jet pump 13 is transferred to steam heating chamber 19, where heat-conducting layer 34 heats and sterilizes the dairy products inside the secondary fermentation chamber. The heated steam flows along return transmission pipe 35 to air storage chamber 33 for storage. Then, the integrated stirring and ventilation mechanism is periodically activated to control the stirring component 17 to stir the dairy products inside the fermentation chamber. While the stirring component 17 is running, it drives the automatic air intake component in the circulating air intake chamber 20 to transfer the purified air in the air storage chamber 33 towards the fermentation chamber. This achieves the functions of stirring and ventilating oxygenation of the dairy products. Through analysis of the above operation process and connection structure, it can be found that this device performs dust removal and high-temperature sterilization on the air, and then sterilizes the dairy products before and after fermentation. At the same time, it makes full use of the purified gas and effectively converts the power transmission of the power components to achieve an energy-saving and efficient operation mode of this device.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
