A protein powder pasteurization machine

Abstract

This utility model discloses a protein powder pasteurization machine, belonging to the field of pasteurization machines. It includes a pasteurization tank with a top cover at the upper end, on which a feeding pipe is installed. A speed reduction frame is fixed to the top cover, and a motor is mounted on the speed reduction frame. A cavity is created in the pasteurization tank to work with the stirring structure on the rotating shaft. During the rotation of the crossbar, diagonal bar, scraper, and spiral stirring blades, the connecting shaft drives the spiral stirring blades to rotate at an accelerated speed due to the action of the transmission component. While the material inside the pasteurization tank is being stirred as a whole, localized stirring can also be performed, improving the uniformity of the stirring and allowing sterilization to be completed in a shorter time. An elastic lifting component is used, which rotates the wave ring during the rotation of the connecting shaft. Combined with the support rod and spring, this allows the connecting shaft to perform periodic lifting movements, which in turn drive the spiral stirring blades to lift and lower, further improving the stirring effect.

Description

Technical Field

[0001] This utility model relates to the field of pasteurization machines, and in particular to a protein powder pasteurization machine. Background Technology

[0002] A pasteurizer is a sterilization device used in the processing of protein powder. The sterilization principle of a pasteurizer is to kill pathogens and most harmful microorganisms in food by treating it within a certain temperature range (usually 60℃ to 90℃) and by using appropriate temperature and holding time, while retaining a small number of harmless or beneficial bacteria or bacterial spores.

[0003] Existing patent number CN220750547U discloses a "Pasteurizer for Protein Powder Processing," which uses a stirring rod and a heating rod to heat and mix the extract inside the sterilizer. However, the heating rod and stirring rod in the aforementioned patent have a simple structure, resulting in a generally poor mixing effect on the extract, which affects the uniformity of heating and leads to uneven sterilization. Furthermore, when the mixing uniformity is poor, more time is required to ensure the sterilization effect, making the entire process time-consuming and inefficient. Utility Model Content

[0004] The main purpose of this invention is to provide a protein powder pasteurization machine that can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A protein powder pasteurization machine includes a pasteurization tank. The upper end of the pasteurization tank is provided with a top cover, and a feeding pipe is installed on the top cover. A speed reduction frame is fixed on the top cover, and a motor is installed on the speed reduction frame. The interior of the pasteurization tank is provided with a rotating shaft connected to the speed reduction frame, and a stirring structure is installed on the rotating shaft. The pasteurization tank is provided with a cavity, and a first water inlet pipe and a second water inlet pipe are fixed at the lower end of the pasteurization tank. A discharge pipe is provided at the lower end of the pasteurization tank.

[0007] Preferably, a drain pipe is provided at the upper end of the sterilizer tank, and the drain pipe is connected to the cavity.

[0008] Preferably, the outer surface of the sterilizer tank is provided with a support, and the support is distributed in a ring array on the sterilizer tank.

[0009] Preferably, the stirring structure includes a mounting sleeve, a crossbar, an inclined bar, a scraper, a connecting shaft, a spiral stirring blade, a transmission assembly, and an elastic lifting assembly. The mounting sleeve is fixed on the rotating shaft. The crossbar and the inclined bar are connected to the mounting sleeve, and the ends of the crossbar and the inclined bar are connected to the scraper. The connecting shaft is fixedly connected to the spiral stirring blade and is rotatably mounted on the crossbar and the inclined bar. The transmission assembly is mounted on the top cover and is connected to the connecting shaft. The elastic lifting assembly is installed at the position where the connecting shaft connects to the crossbar.

[0010] Preferably, the transmission assembly includes a mounting ring, a fixing rod, a gear ring, and a gear. The mounting ring is fixedly connected to the fixing rod and is mounted on the top cover. The gear ring is fixed to the lower end of the fixing rod. The gear is mounted on the connecting shaft and meshes with the gear ring.

[0011] Preferably, the elastic lifting assembly includes a circular plate, a connecting plate, a spring, a support rod, and a wave ring. The circular plate and the wave ring are fixed on the connecting shaft. The connecting plate and the spring are fixedly connected and sleeved on the connecting shaft. The connecting plate and the spring are located between the crossbar and the circular plate. The support rod is fixed on the crossbar, and the upper end of the support rod contacts the wave ring.

[0012] Compared with the prior art, this utility model has the following beneficial effects: The protein powder pasteurizer has a cavity in the pasteurizer tank, which works in conjunction with the stirring structure on the rotating shaft. During the rotation of the crossbar, inclined bar, scraper, and spiral stirring blades, the connecting shaft drives the spiral stirring blades to rotate at an accelerated speed due to the action of the transmission component. While the material inside the pasteurizer tank is being stirred as a whole, local stirring can also be performed, improving the uniformity of stirring and thus increasing the uniformity of heating. This allows for sterilization to be completed in a shorter time. The use of an elastic lifting component, which rotates the wave ring during the rotation of the connecting shaft, works in conjunction with the support rod and spring to allow the connecting shaft to perform periodic lifting movements, which in turn drive the spiral stirring blades to lift, further improving the stirring effect. The structure is simple and the performance is excellent. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figures 1-5 As shown, a protein powder pasteurizer includes a pasteurizer tank 1. The upper end of the pasteurizer tank 1 is provided with a top cover 2, and a feeding pipe 3 is installed on the top cover 2. A reduction gear 4 is fixed on the top cover 2, and a motor 5 is installed on the reduction gear 4. Inside the pasteurizer tank 1, there is a rotating shaft 6 connected to the reduction gear 4, and a stirring structure 7 is installed on the rotating shaft 6. The pasteurizer tank 1 has a cavity 8, and a first water inlet pipe 9 and a second water inlet pipe 10 are fixed to the lower end of the pasteurizer tank 1. A discharge pipe 12 is provided at the lower end of the pasteurizer tank 1. A drain pipe 11 is provided at the upper end of the pasteurizer tank 1, and the drain pipe 11 is connected to the cavity 8. A support 13 is provided on the outer surface of the pasteurizer tank 1, and the support 13 is distributed in a ring array on the pasteurizer tank 1.

[0021] During the processing of protein powder, when sterilizing the extract, the sterilizer tank 1 is stably supported by the legs on the support frame 13. The extract is added into the sterilizer tank 1 through the feeding pipe 3 on the top cover 2. After the end cap on the feeding pipe 3 is closed, the motor 5 is started. The motor 5 drives the rotating shaft 6 to rotate at a reduced speed through the reduction frame 4, thereby rotating the stirring structure 7 to stir and mix the extract. Hot water is injected into the cavity 8 through the first water inlet pipe 9 to heat the extract inside the sterilizer tank 1, thereby achieving the pasteurization effect. Excess hot water is discharged through the drain pipe 11. After pasteurization is completed, cold water is injected into the cavity 8 through the second water inlet pipe 10 to cool the extract, facilitating rapid cooling. Excess cold water is also discharged through the drain pipe 11. After all operations are completed, the extract is discharged through the discharge pipe 12.

[0022] According to the above implementation scheme, the stirring structure 7 includes a mounting sleeve 701, a crossbar 702, an inclined bar 703, a scraper 704, a connecting shaft 705, a spiral stirring blade 706, a transmission assembly 707, and an elastic lifting assembly 708. The mounting sleeve 701 is fixed on the rotating shaft 6. The crossbar 702 and the inclined bar 703 are connected to the mounting sleeve 701, and the ends of the crossbar 702 and the inclined bar 703 are connected to the scraper 704. The connecting shaft 705 is fixedly connected to the spiral stirring blade 706, and the connecting shaft 705 is rotatably mounted on the crossbar 702 and the inclined bar 703. The transmission assembly 707 is mounted on the top cover 2, and the transmission assembly 707 is connected to the connecting shaft 705. The elastic lifting assembly 708 is installed at the position where the connecting shaft 705 is connected to the crossbar 702.

[0023] When the stirring structure 7 is running, the mounting sleeve 701, crossbar 702, and inclined bar 703 of the rotating shaft 6 rotate, and the scraper 704, connecting shaft 705, and spiral stirring blade 706 rotate together to stir and mix. During this process, under the action of the transmission component 707, the connecting shaft 705 carries the spiral stirring blade 706 to rotate at the crossbar 702, which can achieve a local stirring effect. Under the action of the elastic lifting component 708, the connecting shaft 705 and spiral stirring blade 706 can also be raised and lowered during rotation, further improving the stirring effect and increasing the overall uniformity of stirring and mixing. In addition to stirring, the scraper 704 scrapes the inner wall of the sterilizer tank 1, which can prevent a large amount of material from adhering during discharge.

[0024] The transmission assembly 707 includes a mounting ring 7071, a fixing rod 7072, a gear ring 7073, and a gear 7074. The mounting ring 7071 is fixedly connected to the fixing rod 7072 and is mounted on the top cover 2. The gear ring 7073 is fixed to the lower end of the fixing rod 7072. The gear 7074 is mounted on the connecting shaft 705 and meshes with the gear ring 7073.

[0025] When the mounting sleeve 701 rotates with the crossbar 702 and scraper 704, the connecting shaft 705 rotates together. Since the gear ring 7073 is fixed by the fixing rod 7072 and the mounting ring 7071, the gear 7074 moves around the gear ring 7073 during the rotation of the connecting shaft 705, driving the connecting shaft 705 to rotate on the crossbar 702, thereby achieving the effect of accelerating the rotation of the spiral stirring blade 706. This allows for localized stirring and improves the overall uniformity of stirring.

[0026] The elastic lifting assembly 708 includes a circular plate 7081, a connecting plate 7082, a spring 7083, a support rod 7084, and a wave ring 7085. The circular plate 7081 and the wave ring 7085 are fixed on the connecting shaft 705. The connecting plate 7082 and the spring 7083 are fixedly connected and sleeved on the connecting shaft 705. The connecting plate 7082 and the spring 7083 are located between the crossbar 702 and the circular plate 7081. The support rod 7084 is fixed on the crossbar 702, and the upper end of the support rod 7084 contacts the wave ring 7085.

[0027] During the rotation of the connecting shaft 705, the wave ring 7085 will rotate along with it. Under the action of the spring 7083 and the circular plate 7081 on the connecting plate 7082, the connecting shaft 705 has a downward tendency. During the rotation of the wave ring 7085, in conjunction with the support rod 7084 and other structures, the connecting shaft 705 can be raised and lowered. During the movement, when the contact point between the wave ring 7085 and the support rod 7084 goes from high to low, the wave ring 7085 rises, thereby raising the connecting shaft 705 and the spiral stirring blade 706. When the contact point between the wave ring 7085 and the support rod 7084 goes from low to high, the wave ring 7085 descends, thereby lowering the connecting shaft 705 and the spiral stirring blade 706, thus realizing the raising and lowering process.

[0028] It should be noted that a cavity 8 is opened in the sterilizer tank 1, which is used in conjunction with the stirring structure 7 on the rotating shaft 6. During the rotation of the crossbar 702, inclined bar 703, scraper 704, and spiral stirring blade 706, the connecting shaft 705 drives the spiral stirring blade 706 to rotate at an accelerated speed due to the action of the transmission component 707. While the material inside the sterilizer tank 1 is stirred as a whole, local stirring can be performed, which improves the uniformity of stirring and thus increases the uniformity of heating. Sterilization can be completed in a shorter time. The elastic lifting component 708 is used, which drives the wave ring 7085 to rotate during the rotation of the connecting shaft 705. In conjunction with the support rod 7084 and spring 7083, the connecting shaft 705 can perform periodic lifting and lowering movements, which in turn drive the spiral stirring blade 706 to lift and lower, further improving the stirring effect. The structure is simple and the performance is excellent.

[0029] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
