Description

TECHNICAL FIELD

[0001] The present application relates to condensed milk production technology field, specifically to condensed milk production process and equipment. BACKGROUND

[0002] Condensed milk is a kind of milk product, which is made of fresh milk or goat milk through sterilization and concentration. It has the characteristics of long storage time. The common production process is to sterilize the milk at high temperature, then mix it with sucrose, and then compress or concentrate.

[0003] The existing Chinese patent with publication number CN114558492B discloses a shearing and batching mechanism for condensed milk production, which includes a dissolving tank. The bottom of the dissolving tank is connected with a discharge pipe with an electromagnetic valve. A hole is formed in the inner bottom of the middle of the dissolving tank, and a rotating pipe is rotatably installed in the hole. A first rotating shaft is rotatably installed on the inner wall of the rotating pipe. An installation pipe is fixed to the outer wall of the rotating pipe through a bent rod. A second rotating shaft is rotatably installed on the inner wall of the installation pipe. A circular ring plate is installed on the inner wall of the dissolving tank near the second rotating shaft. A filter hole is formed in the top of the circular ring plate. A rolling roller is fixed to one end of the second rotating shaft near the circular ring plate. A transmission assembly is arranged between the first rotating shaft and the second rotating shaft. A storage chamber for storing sucrose is arranged on the inner wall of the dissolving tank near the top.

[0004] The above technical solution provides a solution to accelerate the dissolution of sucrose, which can accelerate the dissolution of sucrose to some extent. However, the solid sucrose needs time to dissolve in milk, and it is more likely to crystallize during the concentration of milk. Therefore, in actual application, the above device needs to wait for the milk with fully dissolved sugar, which affects the production efficiency to some extent. SUMMARY

[0005] In view of the above shortcomings of the prior art, the present application provides a condensed milk production process and equipment, which can effectively solve the problem of slow sucrose dissolution in the prior art.

[0006] To achieve the above purpose, the present application realizes the following technical solutions:

[0007] The present application provides a condensed milk production process, which includes an injection cylinder. A feed cylinder is installed through the top plate of the injection cylinder. A first motor is fixedly installed on the top of the injection cylinder. The output end of the first motor is fixedly connected with a rotating shaft. The rotating shaft extends into the injection cylinder and is fixedly connected with a rolling cylinder through a connecting frame. The rolling cylinder is located in the injection cylinder. An injection pipe is fixedly installed through the bottom of the injection cylinder. A heating pot is horizontally fixedly connected to the inner wall of the injection cylinder, which is located below the rolling cylinder.

[0008] The condensed milk production process includes the following steps:

[0009] S1. Remove the milk from the storage tank and sterilize it at high temperature;

[0010] S2. High-temperature sterilized milk is transported to the concentration unit through pipelines. During the transportation process, the crushing cylinder in the injection barrel crushes the sucrose and melts it into liquid through the heating bucket, and then injects it into the milk transported to the concentration unit through the injection tube.

[0011] S3. During the transportation process, the sucrose liquid is mixed with the milk, and the milk is concentrated after entering the concentration device.

[0012] The condensed milk production equipment using the above-mentioned condensed milk production process has a crushing cylinder divided from top to bottom into a preliminary guiding section, a preliminary crushing section, a final guiding section, and a final crushing section. The bottom of the preliminary guiding section is widened and extends vertically downward to form the preliminary crushing section. Multiple contact columns are uniformly fixedly connected to the outer wall of the preliminary crushing section. During rotation, the preliminary guiding section receives and guides the sucrose falling from the feed cylinder into the space between the preliminary crushing section and the inner wall of the injection cylinder. During rotation, the preliminary crushing section contacts and crushes the sucrose, and the contact columns increase the contact with the sucrose. The bottom of the preliminary crushing section is widened to form the final guiding section. The bottom of the final guiding section extends vertically downward to form the final crushing section. The final guiding section restricts the size of the sucrose that can pass through it, allowing smaller sucrose to enter the space between the final crushing section and the inner wall of the injection cylinder. The rotating final crushing section crushes and breaks up the sucrose.

[0013] Furthermore, including an injection cylinder, a guide bucket is fixedly connected to the top of the heating bucket, and a guide groove is provided on the guide bucket.

An air inlet is provided on the back side of the elastic airbag, or an air inlet is provided on the connecting frame between the elastic airbag and the rotating shaft. A one-way valve is installed in both the air outlet and the air inlet.

[0015] Furthermore, the passive magnets on the contact plate have the same magnetic pole facing the injection cylinder, while the active magnets on the injection cylinder have alternating magnetic poles facing the inside of the injection cylinder.

[0035] The present application will be further described below with reference to the embodiments.

[0036] Embodiment:

[0037] The condensed milk production process comprises a syringe 1, a feeding cylinder 2 is installed through the top plate of the syringe 1, a first motor 3 is fixedly installed at the top of the syringe 1, a rotating shaft 5 is fixedly connected to the output end of the first motor 3, the rotating shaft 5 extends into the syringe 1 and is fixedly connected with a rolling cylinder 6 through a connecting frame, the rolling cylinder 6 is in the syringe 1, a syringe tube 22 is fixedly installed through the bottom of the syringe 1, a heating pot 15 is horizontally fixedly connected to the inner wall of the syringe 1, and the heating pot 15 is below the rolling cylinder 6;

[0038] The condensed milk production process comprises the following steps:

[0039] S1, milk is taken out from a storage tank and high-temperature sterilization is performed;

[0040] S2, the high-temperature sterilized milk is conveyed into a concentration device through a pipeline, in the conveying process, the rolling cylinder 6 in the syringe 1 grinds cane sugar and melts it into a liquid state through the heating pot 15, and then the cane sugar liquid is injected into the milk conveyed into the concentration device through the syringe tube 22;

[0041] S3, the cane sugar liquid is mixed in the milk in the conveying process, and the milk is concentrated after entering the concentration device.

[0042] The condensed milk production equipment applying the condensed milk production process, the rolling cylinder 6 is divided into a preliminary guide part 601, a preliminary rolling part 602, a final guide part 604 and a final rolling part 605 from top to bottom, the bottom of the preliminary guide part 601 is expanded in diameter and vertically extended downward to form the preliminary rolling part 602, a plurality of contact columns 603 are uniformly and fixedly connected to the outer side wall of the preliminary rolling part 602, the preliminary guide part 601 receives and guides the falling sugar cane from the feeding cylinder 2 into the space between the preliminary rolling part 602 and the inner wall of the injection cylinder 1 in rotation, the preliminary rolling part 602 contacts and rolls the sugar cane in rotation and increases the contact with the sugar cane through the contact columns 603, the bottom of the preliminary rolling part 602 is expanded in diameter to form the final guide part 604, the bottom of the final guide part 604 is vertically extended downward to form the final rolling part 605, the final guide part 604 limits the size of the sugar cane that can pass through the final guide part 604, and allows smaller sugar cane to enter the space between the final rolling part 605 and the inner wall of the injection cylinder 1, and the rotating final rolling part 605 rolls and crushes the sugar cane.

[0043] Specifically, the injection cylinder 1 is included, the top of the heating pot 15 is fixedly connected with a flow guide hopper 14, and a flow guide groove 16 is formed in the flow guide hopper 14.

[0044] In the installation, the injection pipe 22 is inserted into the pipeline for conveying the high-temperature sterilized milk, and the injection pipe 22 inserted into the pipeline will convey the sucrose into the high-temperature sterilized milk. In the injection cylinder 1, the first motor 3 drives the rolling cylinder 6 to rotate through the rotating shaft 5, and at the same time, the sucrose is conveyed into the injection cylinder 1 through the feeding cylinder 2. After the sucrose enters the injection cylinder 1, it is received by the preliminary guide part 601 and slides to the gap between the preliminary rolling part 602 and the injection cylinder 1 under the guidance of the preliminary guide part 601. The preliminary rolling part 602 contacts the sucrose in rotation and rolls the sucrose to a size smaller than or equal to the gap between the preliminary rolling part 602 and the injection cylinder 1, and breaks the sucrose through the contact between the contact column 603 and the sucrose to avoid the adhesion and clumping of the sucrose. Then the sucrose continues to fall and passes through the final guide part 604. The final guide part 604 guides the sucrose into the gap between the final rolling part 605 and the injection cylinder 1, and the sucrose is rolled by the final rolling part 605 to be finer. The rolled sucrose has a free falling and rotating tendency generated by the rolling cylinder 6. When the sucrose slides out of the final rolling part 605, it is caught by the diversion hopper 14. The heating hopper 15 under the diversion hopper 14 transmits heat to the diversion hopper 14. After the finely rolled sucrose falls onto the diversion hopper 14, it quickly melts into a liquid. At the same time, the melted liquid is guided by the diversion groove 16 to flow in a spiral path on the diversion hopper 14. By extending the sucrose flow path, the sucrose is fully melted. After the flowing sucrose flows down from the surface of the diversion hopper 14, it flows into the high-temperature sterilized milk through the injection pipe 22 and can be fully mixed in the milk. The mixing of the melted sucrose in the milk can make the sucrose dissolve in the milk faster. Since the sucrose is finely rolled before melting, the melting time is short, which can effectively shorten the time of dissolving the sucrose in the milk and improve the production efficiency.

[0045] Specifically, a plurality of groove positions are uniformly provided on the terminal rolling part 605, and an elastic air bag 7 is fixedly connected to the sidewall of the groove position. The outer portion of the elastic air bag 7 is fixedly connected to a contact plate 8. A plurality of vertical pressing strips are arranged on the sidewall of the contact plate 8 close to the injection cylinder 1. Passive magnets 12 are fixedly connected to the top end and the low end of the sidewall of the contact plate 8 close to the injection cylinder 1. A plurality of active magnets 13 are uniformly fixedly connected to the outer wall of the injection cylinder 1. Two air outlet holes 10 are provided on the elastic air bag 7 and the rolling cylinder 6. The two air outlet holes 10 are respectively located above and below the elastic air bag 7. An air inlet hole 11 is provided on the back side of the elastic air bag 7 or the connecting frame of the elastic air bag 7 and the rotating shaft 5. A one-way valve is installed in each of the air outlet hole 10 and the air inlet hole 11.

[0046] Specifically, the passive magnets 12 on the contact plate 8 are of the same magnetic pole towards the injection cylinder 1, and the active magnets 13 on the injection cylinder 1 are of the alternating magnetic pole towards the inside of the injection cylinder 1.

[0047] When the rolling cylinder 6 is driven to rotate by the first motor 3, the elastic air bag 7 in the final rolling part 605 slot is rotated together, at the same time, the continuously rotating elastic air bag 7 will continuously pass through the magnetic field range of the active magnet 13 under the action of the alternating magnetic pole of the active magnet 13, and the passive magnet 12 will be continuously subjected to the magnetic attraction and repulsion of the active magnet 13 to the passive magnet 12, so that the elastic air bag 7 is continuously compressed and expanded in the process of rotation. When the elastic air bag 7 is compressed, the gas in the elastic air bag 7 is sprayed out of the gas outlet 10 to blow the sugar cane above and the sugar cane falling from the final rolling part 605. When the sugar cane is blown upward, it can push the sugar cane upward, make the friction between the sugar cane and the rolling cylinder 6 more, and make the contact between the sugar cane and the rolling cylinder 6 more sufficient. When the sugar cane is blown downward, it can blow the sugar cane and speed up the falling speed of the sugar cane, reduce the adhesion of the sugar cane and speed up the melting progress of the sugar cane. In the process of expansion of the elastic air bag 7, the passive magnet 12 on the contact plate 8 is attracted by the active magnet 13, so that the pressing strip on the contact plate 8 extends and adheres to the inner wall of the injection cylinder 1, and the vertical pressing strip presses the sugar cane on the inner wall of the injection cylinder 1. At the same time of rotation, the sugar cane is sufficiently rolled to further reduce the diameter of the sugar cane, help promote the melting of the sugar cane, and the expansion of the elastic air bag 7 will be filled with air through the air inlet 11. The position of the air inlet 11 is at the back side of the elastic air bag 7, towards the inside of the rolling cylinder 6. The elastic air bag 7 connected with the connecting frame of the rotating shaft 5 needs to open the air inlet 11 on the connecting frame of the rotating shaft 5.

[0048] Specifically, the elastic metal sheet 24 is embedded and installed on the opposite two side walls of the injection pipe 22, the top and bottom of the elastic metal sheet 24 are fixed with the injection pipe 22, the two sides of the injection pipe 22 are fixedly connected with the fixed plate 18, the rotating shaft 19 is rotatably installed on the two fixed plates 18, the gears 17 are fixedly connected at one end of the two rotating shafts 19 and mesh with each other, the second motor 4 is connected with one of the gears 17, the hollow plate 20 is fixedly connected with the rotating shaft 19, and the extrusion plate 21 is elastically and slidingly inserted in the hollow plate 20.

[0049] The starting of the second motor 4 drives the rotation shaft 19 to rotate, and through the engagement of the two gears 17, the rotation directions of the two rotation shafts 19 are opposite, the hollow plates 20 on the two rotation shafts 19 rotate in different directions, and rotate in the directions shown in the figure. The extrusion plates 21 in the two rotations will contact the upper half of the elastic metal sheet 24 and rotate to the lower half of the elastic metal sheet 24. Through the extrusion of the extrusion plate 21, the sucrose in the injection pipe 22 is extruded into the conveying pipe of the high-temperature sterilized milk, so that the sucrose is fully extruded into the milk and mixed.

[0050] Specifically, a plurality of heating plates 25 are obliquely and rotatably installed on the inner walls of the opposite sides of the injection pipe 22, the plurality of heating plates 25 are alternately arranged left and right and up and down, a circular arc plate 26 is transversely and fixedly installed on the top wall of the heating plate 25, and a plurality of particle retaining grooves 27 are formed on the side of the circular arc plate 26 facing the top of the heating plate 25.

[0051] Specifically, part of the heating plates 25 are provided with a hollow groove 9, and the heating plates 25 at the uppermost and lowermost positions in the injection pipe 22 are not provided with the hollow groove 9. A rotating plate 23 is elastically and rotatably installed in the hollow groove 9 through a spring. One side of the rotating plate 23 extends to the outside of the heating plate 25. A switch 29 is fixedly installed on the inner wall of the hollow groove 9. A fixed frame 28 is fixedly installed below the heating plate 25 on the inner wall of the injection pipe 22. The fixed frame 28 and the heating plate 25 are fixedly connected by a spring. The switch 29 controls the on-off state of the spring between the heating plate 25 and the fixed frame 28.

[0052] The sucrose flowing into the injection pipe 22 will contact the elastic metal sheet 24 in the injection pipe 22 and flow between the plurality of alternating elastic metal sheets 24. This part of the sucrose will be heated by the elastic metal sheet 24, avoiding small particles that have not melted in the sucrose. At the same time, if there are still small particles that have not melted in the sucrose, when passing through the surface of the circular arc plate 26, the small particles will enter the particle retaining groove 27 and melt into liquid under the heating of the heating plate 25, and then be carried out by the flowing sucrose. It can further ensure that the sucrose mixed with the milk is fully melted, and ensure the mixing speed of the sucrose and the milk.

[0053] At the same time, in the flow process of sucrose, part of the sucrose may produce local cooling in the process of flowing into the injection pipe 22, and the part of the cooled sucrose has stronger viscosity and poorer flowability, and is more prone to stay and gather. The cooled sucrose has greater pressure on the rotating plate 23 when flowing through the rotating plate 23 due to the characteristics of easy gathering and greater viscosity, and forces the rotating plate 23 to rotate. The reason is that the part of the cooled sucrose is prone to form a small lump and adhere to the surrounding sucrose, has poor flowability, is more prone to stay on the surface of the rotating plate 23 and has greater gravity. At this time, the spring between the rotating plate 23 and the empty groove 9 is pressed and shrinks, so that the rotating plate 23 contacts the switch 29, forces the spring between the heating plate 25 and the fixed frame 28 to be de-energized, and the spring is stretched after being de-energized, so as to lift the heating plate 25 upward, reduce the inclination of the heating plate 25, slow down the flow speed of the sucrose, prolong the flow time of the sucrose on the heating plate 25, and make the sucrose be heated sufficiently, and further ensure the sufficient melting of the sucrose. After the cooled sucrose slowly leaves the surface of the rotating plate 23, the rotating plate 23 is reset under the action of the spring, loses the contact with the switch 29, and the spring between the heating plate 25 and the contact plate 8 is energized. When the spring has current, a magnetic field is generated on each turn of the spring and is displayed in the same arrangement direction. At this time, the magnetic fields on each turn of the spring are adjacent to each other with opposite poles and are attracted to each other, so that the spring is shrunk and the original inclination of the heating plate 25 is restored.

[0054] It should be noted that the first motor 3 and the second motor 4 are fixedly connected with the external support structure, and the connection mode needs to be limited according to the actual scene, and the operation principle belongs to the prior art, and the position and principle are not limited further. At the same time, the heating pot 15 and the heating plate 25 are heated by the built-in heating wire, which belongs to the prior art, and the working principle is not described in detail.

[0055] The above embodiments are only used to illustrate the technical solutions of the present application, but not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can be modified, or some technical features can be replaced by equivalents; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the protection scope of the technical solutions of the embodiments of the present application.
