Description

A cream negative pressure degassing and defoaming device Technical Field

[0001] This application relates to the field of cream production technology, for example to a cream negative pressure degassing and defoaming device. Background Technology

[0002] Currently, in the food processing industry, especially in the production of cream, the presence of air bubbles is a common problem. Air bubbles not only affect the texture and taste of cream but can also lead to a decrease in its stability during storage and use. Traditional defoaming methods include settling, stirring, and filtering, but these methods are inefficient and struggle to completely remove the tiny air bubbles from the cream. In recent years, negative pressure defoaming technology has been increasingly applied to cream processing. By reducing environmental pressure, air bubbles expand and burst, thereby achieving the purpose of defoaming.

[0003] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art:

[0004] However, when using a traditional negative pressure defoaming device for cream, the cream remains stationary inside the can, resulting in a significant height difference between the bottom and top layers of cream. This causes the bubbles to rise too slowly from the bottom to the surface, hindering the rapid defoaming of the cream. Summary of the Invention

[0005] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0006] This disclosure provides a negative pressure degassing and defoaming device for cream to solve the problem of slow defoaming speed in cream.

[0007] In some embodiments, the cream negative pressure degassing and defoaming device includes: a storage tank with a conveying pipe connected to its bottom; a defoaming tank with a discharge pipe vertically arranged at its bottom, the upper end of the discharge pipe extending to the upper part of the defoaming tank, and the bottom of the discharge pipe connected to the conveying pipe; a spreading tray disposed at the upper end of the discharge pipe, and the spreading tray having a circular plate structure; an extrusion disc movably disposed at the upper part of the discharge pipe, and a positioning rod vertically disposed on the lower side of the middle part of the extrusion disc, the positioning rod being inserted into the discharge pipe; and a vacuum pump disposed at the upper part of the defoaming tank, and the vacuum pump being connected to the defoaming tank.

[0008] In some embodiments, a guide groove is provided on the side of the positioning rod, and the guide groove is arranged along the length direction of the positioning rod.

[0009] In some embodiments, a material-throwing disc is rotatably provided on the underside of the material-spreading disc.

[0010] In some embodiments, the material throwing disc has a circular structure, and a plurality of material throwing rods are arranged around the side of the material throwing disc, with the material throwing rods closely attached to the side of the defoaming tank.

[0011] In some embodiments, a top plate is fixedly provided on the discharge pipe at the bottom of the throwing disc, a drive motor is provided on the side of the top plate, a gear ring is provided at the bottom of the throwing disc, internal teeth are provided on the inner side of the gear ring, a drive gear is provided on the upper part of the drive motor, the drive gear is provided on the upper part of the top plate, and the drive gear is meshed with the internal teeth on the inner side of the gear ring.

[0012] In some embodiments, a control valve is provided in the middle of the delivery pipe.

[0013] In some embodiments, a pressure gauge is provided on the upper part of the defoaming tank.

[0014] In some embodiments, a flow limiting valve is provided on the upper part of the storage tank, and a feeding pipe is also provided on the storage tank, with a feeding valve provided on the feeding pipe.

[0017] The cream negative pressure degassing and defoaming device provided in this embodiment can achieve the following technical effects:

[0018] Through the negative pressure environment and the synergistic effect of the extrusion disc and the spreading disc, air bubbles in the butter can be expelled more effectively. The extrusion disc is pressed on the spreading disc, so that the thickness of the butter is reduced when it passes through the narrow space between the extrusion disc and the spreading disc, making it easier to expel air bubbles, thereby significantly improving the defoaming efficiency.

[0019] The design of the spreading tray and the swishing tray allows the cream to be evenly spread and swished onto the inner wall of the defoaming tank during the defoaming process, increasing the surface area of ​​the cream. This not only helps to remove air bubbles but also improves the uniformity of the cream, enhancing the texture and taste of the final product.

[0037] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0038] Referring to Figures 1-4, this embodiment of the present disclosure provides a negative pressure degassing and defoaming device for cream, comprising: a storage tank 100, the bottom of which is connected to a conveying pipe 101; a defoaming tank 200, the bottom of which is vertically provided with a discharge pipe 202, the upper end of which extends to the upper part of the defoaming tank 200, and the bottom of which is connected to the conveying pipe 101; a spreading tray 300, which is disposed at the upper end of the discharge pipe 202, and the spreading tray 300 is a circular plate structure; an extrusion tray 301, which is movably disposed on the upper part of the discharge pipe 202, and a positioning rod 302 is vertically disposed on the lower side of the middle part of the extrusion tray 301, the positioning rod 302 being inserted into the discharge pipe 202; and a vacuum pump 203, which is disposed on the upper part of the defoaming tank 200, and the vacuum pump 203 is connected to the defoaming tank 200.

[0039] The cream negative pressure degassing and defoaming device provided in this embodiment has a sealed tank 100, consisting of a tank body and a lid. Whipped cream can be stored inside the tank 100. A conveying pipe 101 is connected to the bottom of the tank 100. The defoaming tank 200 is also a sealed tank structure. A discharge pipe 202 is installed inside the defoaming tank 200. One end of the discharge pipe 202 is connected to the bottom of the defoaming tank 200, and the other end is located on the upper side inside the defoaming tank 200. The discharge pipe 202 is connected to the conveying pipe 101. The cream in the sample storage tank 100 can be conveyed to the discharge pipe 202 through the conveying pipe 101. The cream can overflow from the upper end of the discharge pipe 202. As it overflows, the cream flows in different directions, which can break larger air bubbles mixed in with the cream, thereby achieving the discharge of larger air bubbles. The spreading tray 300 at the top of the discharge pipe 202 is set at the top of the discharge pipe 202, so that the overflowing cream can flow into the spreading tray 300. The spreading tray 300 can spread the cream evenly, increasing the spread area of ​​the cream. The negative pressure can make the spread cream even more even. To effectively remove air bubbles, an extrusion disc 301 is installed at the upper part of the discharge pipe 202. The extrusion disc 301 is pressed against the upper part of the spreading disc 300, allowing the overflowing cream to flow between the extrusion disc 301 and the spreading disc 300. This results in a thinner overflow, better venting of internal air bubbles. A positioning rod 302 is located in the lower center of the extrusion disc 301, inserted into the discharge pipe 202. The diameter of the positioning rod 302 is smaller than that of the discharge pipe 202, facilitating cream overflow while preventing lateral displacement of the extrusion disc 301. This is achieved through a vacuum pump. The evacuation of the defoaming tank 200 by 203 can create a negative pressure inside the defoaming tank 200. This negative pressure allows cream to be transported into the defoaming tank 200 through the discharge pipe 202. Furthermore, the extrusion plate 301 pressing against the discharge pipe 202 can control the speed at which cream overflows from the discharge pipe 202, thereby better controlling the pressure inside the defoaming tank 200. This prevents the cream from flowing out of the discharge pipe 202 too quickly, which would cause the negative pressure inside the defoaming tank 200 to decrease too rapidly. This stabilizes the negative pressure inside the defoaming tank 200 and allows for better removal of air bubbles from the cream.

[0040] Optionally, a guide groove 303 is provided on the side of the positioning rod 302, and the guide groove 303 is arranged along the length direction of the positioning rod 302.

[0041] In this way, the guide groove 303 on the side of the positioning rod 302 can facilitate the flow of cream, which can prevent the positioning rod 302 from blocking the discharge pipe 202 and increase the flow rate of cream when it passes through.

[0042] Optionally, a material-throwing disc 304 is rotatably provided on the lower side of the material-spreading disc 300.

[0043] In this way, the swiping tray 304 at the bottom of the spreading tray 300 can rotate, which can swish out the cream that overflows from the spreading tray 300. This can prevent too much cream from accumulating on the spreading tray. The swiping tray 304 can also swish the cream onto the inner wall of the defoaming tank 200. The cream flows down the inner wall of the defoaming tank 200, which can better increase the spreading area of ​​the cream and better defoam.

[0044] Optionally, the material throwing disc 304 has a circular structure, and a plurality of material throwing rods 305 are arranged around the side of the material throwing disc 304, with the material throwing rods 305 closely attached to the side of the defoaming tank 200.

[0045] Thus, the sling plate 304 has a circular structure, which can reduce vibration when the sling plate rotates. The sling rods 305 on the side of the sling plate 304 are closely spaced, which can facilitate the downward flow of cream. The sling rods 305 are close to the inner wall of the defoaming tank 200, which can facilitate the delivery of cream to the inner wall of the defoaming tank 200.

[0046] Optionally, a top plate 204 is fixedly installed on the discharge pipe 202 at the bottom of the throwing disc 304. A drive motor 205 is installed on the side of the top plate 204. A gear ring 306 is installed at the bottom of the throwing disc 304. An internal tooth 307 is installed on the inner side of the gear ring 306. A drive gear 206 is installed on the upper part of the drive motor 205. The drive gear 206 is installed on the upper part of the top plate 204, and the drive gear 206 meshes with the internal tooth 307 on the inner side of the gear ring 306.

[0047] In this way, the top plate 204 at the bottom of the throwing disc 304 can support the throwing plate. The top plate 204 is fixed on the discharge pipe 202. The top plate 204 can support the throwing plate, so that the throwing plate can be supported on the top plate 204. The drive motor 205 is fixedly installed on the top plate 204. The drive motor 205 can drive the drive gear 206. The bottom of the throwing plate is coaxially provided with a gear ring 306. The gear ring 306 has internal teeth 307. The drive wheel can drive the internal teeth 307 and the gear ring 306 to rotate, thereby driving the throwing disc 304 to rotate.

[0048] Optionally, a control valve 102 is provided in the middle of the delivery pipe 101.

[0049] In this way, the control valve 102 on the delivery pipe 101 can control the cream in the storage tank 100 to enter the defoaming tank 200, and by closing the control valve 102, the vacuum pump 203 can supply pressure to the defoaming tank 200, so that the cream in the defoaming tank 200 can be discharged.

[0050] Optionally, a pressure gauge 207 is provided on the upper part of the defoaming tank 200.

[0051] In this way, the pressure gauge 207 on the bubble tank 200 can monitor the air pressure inside the tank.

[0052] Optionally, a flow limiting valve 103 is provided on the upper part of the storage tank 100, and a feeding pipe 104 is also provided on the storage tank 100, with a feeding valve 105 provided on the feeding pipe 104.

[0053] In this way, the flow-limiting valve 103 at the top of the storage tank 100 controls the air intake speed. By controlling the air intake speed, the speed at which the cream in the storage tank 100 enters the defoaming tank 200 can be controlled. When the feeding valve 105 on the feeding pipe 104 is opened, the cream can be added.

[0054] Optionally, the bottom of the defoaming tank 200 is provided with a discharge pipe 208, and a discharge valve 209 is provided on the discharge pipe 208.

[0055] In this way, the discharge pipe 208 at the bottom of the defoaming tank 200 can discharge the defoamed cream, and the discharge valve 209 can control the opening and closing of the discharge pipe 208.

[0056] Optionally, a top ring 210 is provided on the outer side of the top plate 204, and an annular groove 308 is provided at the bottom of the throwing disc 304, with the top ring 210 extending into the annular groove 308.

[0057] In this way, the top ring 210 on the outer side of the top plate 204 protrudes upward, and the bottom of the sling tray 304 is recessed inward with an annular groove 308. The top ring 210 extends into the annular groove 308, which can prevent the cream on the sling tray 304 from entering the top plate 204.
