Description

Technical Field

[0001] This utility model relates to the field of whole milk powder production technology, specifically to a high-efficiency mixing device for whole milk powder production. Background Technology

[0002] Whole milk powder: A powder (or block) product made solely from cow's or goat's milk through concentration and drying. Produced with pure milk, it largely retains the original nutritional components of the milk, with protein no less than 24%, fat no less than 26%, and lactose no less than 37%. Current milk powder production processes often suffer from insufficient mixing, leading to a reduction in the nutritional value of the milk powder and affecting its production quality. Furthermore, the mixing equipment is prone to vibration during operation, impacting mixing quality and reducing the equipment's lifespan.

[0003] As disclosed in Chinese Patent Publication No. CN215139312U, a pneumatic milk powder mixing device for milk powder production is used. During use, milk powder and nutrients are added into the machine body through the feed hopper. The mixing blades stir and mix the milk powder and nutrients. Gas is supplied through the first gas supply pipe, the second gas supply pipe and the connecting pipe. The air nozzle blows the milk powder and nutrients inside upward, so that the mixing blades stir and mix them multiple times. This effectively improves the mixing quality of the mixing device and avoids a large amount of sediment during mixing, which would cause uneven mixing and affect the mixing quality. After mixing is completed, the solenoid valve is opened by the control panel to discharge the material.

[0004] However, the pneumatic milk powder mixing device for milk powder production mentioned in the above application uses fixed mixing blades to stir the milk powder, which is not sufficiently stirred and milk residue remains on the inner wall of the box. Therefore, it has certain limitations.

[0005] Therefore, we urgently need to provide a high-efficiency mixing device for the production of whole milk powder. Utility Model Content

[0006] The purpose of this invention is to provide a high-efficiency mixing device for the production of whole milk powder, in order to solve the problem of insufficient mixing and milk residue remaining on the inner wall of the box when the pneumatic milk powder mixing device for milk powder production mentioned in the background art is used to mix milk powder by fixed mixing blades.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency mixing device for whole milk powder production, comprising a mixing box and support legs, wherein the four support legs are respectively fixedly connected to the four corners of the lower surface of the mixing box, and the mixing box is provided with a mixing and stirring device and a cleaning device.

[0008] The mixing and stirring device includes a heating unit, a driving unit, a stirring unit, and a feeding and discharging unit.

[0009] The heating unit includes an electric heating plate and a heating inner liner. The four electric heating plates are fixedly installed in a ring on the inner wall of the mixing tank. The heating inner liner is fixedly installed inside the mixing tank, and its outer wall is in close contact with the inner wall of the electric heating plate. The electric heating plate heats the emulsion inside the heating inner liner to keep it at a suitable temperature.

[0010] A further improvement is that the drive unit includes a drive motor, a worm gear, and a worm wheel. The drive motor is installed on the top right side of the mixing chamber. The right end of the worm gear is connected to the output end of the drive motor. The worm wheel is meshed with the outer surface of the worm gear. The drive motor drives the worm gear to rotate, which in turn drives the worm wheel to rotate, thereby driving the internal stirring unit to rotate and fully stir and mix the emulsion.

[0011] A further improvement is that the stirring unit includes a rotating mechanism and a stirring mechanism.

[0012] The rotating mechanism includes a bearing, a stirring shaft, and stirring rods. The bearing is installed at the top center of the mixing tank. The stirring shaft is fixedly connected to the inside of the worm gear and rotatably connected to the inside of the bearing. Its bottom extends into the bottom of the heating inner liner. The four sets of stirring rods are fixedly connected to the outer surface of the stirring shaft in a ring of three at equal intervals. The stirring shaft rotates inside the bearing, thereby driving the stirring rods to rotate, thus fully stirring the emulsion inside the heating inner liner.

[0013] A further improvement is that the stirring mechanism includes a telescopic spring, a sliding sleeve, and stirring plates. The telescopic spring is arranged around the outer surface of the stirring rod, and its inner end is fixedly connected to the stirring shaft. The sliding sleeve is sleeved on the outer surface of the stirring rod, and its inner side is fixedly connected to the outer end of the telescopic spring. The five stirring plates are fixedly connected to the outer surface of the sliding sleeve in a buffer configuration. When the stirring shaft rotates, centrifugal force is generated, which in turn drives the telescopic spring to extend from the inside to the outside, thereby driving the sliding sleeve to rotate outward on the stirring rod, thus driving the stirring plates to rotate. When the telescopic spring is stretched to its limit, it will rebound, thereby driving the sliding sleeve to return to its original position, thus realizing the reciprocating cyclic stirring of the stirring plates, which better achieves the effect of stirring the emulsion.

[0014] A further improvement is that the outer surface of the stirring plate is provided with equidistant turbulence holes. The turbulence holes allow the stirring plate to better cut the emulsion while rotating, thereby further improving the stirring effect.

[0015] A further improvement is that the feeding and discharging unit includes a feeding hopper, a discharging pipe, and an electromagnetic sealing valve. The feeding hopper is fixedly connected to the top left side of the mixing chamber, the discharging pipe is fixedly connected to the bottom right side of the mixing chamber, and the electromagnetic sealing valve is installed on the outer surface of the discharging pipe. The emulsion and sucrose are added to the interior of the heating inner liner through the feeding hopper, and the discharging time is controlled by the electromagnetic valve.

[0016] A further improvement is that the cleaning device includes a connecting ring, a support rod, and a scraper. The two connecting rings are respectively fixedly connected to the upper and lower sides of the outer surface of the stirring shaft. The two sets of support rods are respectively fixedly connected to the left and right sides of the connecting rings in pairs. The two scrapers are fixedly connected to the outer ends of the two sets of support rods. When the stirring shaft rotates, the support rods drive the scrapers to rotate, thereby rotating and scraping off the emulsion on the inner wall of the heated inner liner to avoid emulsion residue and waste of resources.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This high-efficiency mixing device for whole milk powder production drives the stirring shaft to rotate via a drive unit, which in turn drives the stirring rod to rotate, thereby fully stirring the emulsion inside the heating tank. It works in conjunction with an electric heating plate to heat the emulsion inside the heating tank, keeping it at a suitable temperature for stirring and mixing.

[0019] 2. This high-efficiency mixing device for whole milk powder production generates centrifugal force while the stirring shaft rotates, which in turn drives the telescopic spring to extend from the inside to the outside, thereby causing the sliding sleeve to rotate outward on the stirring rod, which in turn drives the stirring plate to rotate. When the telescopic spring is stretched to its limit, it will rebound, thereby driving the sliding sleeve to return to its original position, thus realizing the reciprocating cyclic stirring of the stirring plate, which better achieves the effect of stirring the emulsion.

[0020] 3. This high-efficiency mixing device for whole milk powder production uses a support rod to drive a scraper to rotate while the stirring shaft rotates, thereby scraping off the emulsion on the inner wall of the heated inner tank, avoiding emulsion residue and resource waste.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5 This utility model provides a technical solution: Example 1:

[0029] A high-efficiency mixing device for whole milk powder production includes a mixing chamber 1 and four support legs 2. The four support legs 2 are fixedly connected to the four corners of the lower surface of the mixing chamber 1, and a mixing and stirring device is provided inside the mixing chamber 1.

[0030] The mixing and stirring device includes a heating unit, a driving unit, a stirring unit, and a feeding and discharging unit.

[0031] The heating unit includes an electric heating plate 301 and a heating inner liner 302. Four electric heating plates 301 are fixedly installed in a ring on the inner wall of the mixing tank 1. The heating inner liner 302 is fixedly installed inside the mixing tank 1, and its outer wall is in close contact with the inner wall of the electric heating plate 301. The electric heating plate 301 heats the emulsion inside the heating inner liner 302 to keep it at a suitable temperature.

[0032] The drive unit includes a drive motor 303, a worm gear 304, and a worm wheel 305. The drive motor 303 is mounted on the top right side of the mixing chamber 1. The right end of the worm gear 304 is connected to the output end of the drive motor 303. The worm wheel 305 is meshed with the outer surface of the worm gear 304. The drive motor 303 drives the worm gear 304 to rotate, which in turn drives the worm wheel 305 to rotate, thereby driving the internal stirring unit to rotate and fully stir and mix the emulsion.

[0033] The stirring unit includes a rotating mechanism and a stirring mechanism.

[0034] The rotating mechanism includes a bearing 306, a stirring shaft 307, and stirring rods 308. The bearing 306 is installed at the top center of the mixing tank 1. The stirring shaft 307 is fixedly connected to the inside of the worm gear 305 and rotatably connected to the inside of the bearing 306. Its bottom extends into the bottom of the heating inner tank 302. Four sets of stirring rods 308 are fixedly connected to the outer surface of the stirring shaft 307 in a ring of three at equal intervals. The stirring shaft 307 rotates inside the bearing 306, thereby driving the stirring rods 308 to rotate, thus fully stirring the emulsion inside the heating inner tank 302.

[0035] The stirring mechanism includes a telescopic spring 309, a sliding sleeve 310, and stirring plates 311. The telescopic spring 309 is arranged around the outer surface of the stirring rod 308, and its inner end is fixedly connected to the stirring shaft 307. The sliding sleeve 310 is sleeved on the outer surface of the stirring rod 308, and its inner side is fixedly connected to the outer end of the telescopic spring 309. Five stirring plates 311 are fixedly connected to the outer surface of the sliding sleeve 310 in a buffered manner. When the stirring shaft 307 rotates, centrifugal force is generated, which in turn drives the telescopic spring 309 to extend from the inside to the outside, thereby driving the sliding sleeve 310 to rotate outward on the stirring rod 308, thereby driving the stirring plates 311 to rotate. When the telescopic spring 309 is stretched to its limit, it will rebound, thereby driving the sliding sleeve 310 to return to its original position, thus realizing the reciprocating cyclic stirring of the stirring plates 311, which better achieves the effect of stirring the emulsion.

[0036] The outer surface of the stirring plate 311 is provided with equidistant turbulence holes. The turbulence holes enable the stirring plate 311 to better cut the emulsion while rotating, thereby further improving the stirring effect.

[0037] The feeding and discharging unit includes a feeding hopper 312, a discharging pipe 313, and an electromagnetic sealing valve 314. The feeding hopper 312 is fixedly connected to the top left side of the mixing chamber 1, the discharging pipe 313 is fixedly connected to the bottom right side of the mixing chamber 1, and the electromagnetic sealing valve 314 is installed on the outer surface of the discharging pipe 313. The emulsion and sucrose are added into the interior of the heating inner liner 302 through the feeding hopper 312, and the discharging time is controlled by the electromagnetic sealing valve 314.

[0038] In use, the emulsion and sucrose are first introduced into the heating inner tank 302 through the feed hopper 312. Then, the electric heating plate 301 is activated to heat the emulsion inside the heating inner tank 302 and maintain it at a suitable temperature. At the same time, the drive motor 303 is activated to drive the worm gear 304 to rotate, which in turn drives the worm wheel 305 to rotate, which in turn drives the stirring shaft 307 to rotate inside the bearing 306, thereby driving the stirring rod 308 to rotate. As the stirring shaft 307 rotates, centrifugal force is generated, which in turn drives the telescopic spring 309 to extend from the inside to the outside, thereby driving the sliding sleeve 310 to rotate outward on the stirring rod 308, thereby driving the stirring plate 311 to rotate. When the telescopic spring 309 is stretched to its limit, it will rebound, thereby driving the sliding sleeve 310 to return to its original position, thus realizing the reciprocating cyclic stirring of the stirring plate 311, which better achieves the effect of stirring the emulsion. Example 2:

[0039] Based on Example 1, a cleaning device is also provided inside the mixing box 1. The cleaning device includes a connecting ring 401, a support rod 402, and a scraper 403. The two connecting rings 401 are fixedly connected to the upper and lower sides of the outer surface of the stirring shaft 307, respectively. The two sets of support rods 402 are fixedly connected to the left and right sides of the connecting rings 401 in pairs, respectively. The two scrapers 403 are fixedly connected to the outer ends of the two sets of support rods 402.

[0040] While the stirring shaft 307 rotates, the support rod 402 drives the scraper 403 to rotate, thereby rotating and scraping off the emulsion on the inner wall of the heating inner liner 302. When discharging, the support rod 402 also scrapes off the emulsion on the upper and lower walls of the mixing box 1 and discharges it through the discharge pipe 313, so as to avoid the presence of emulsion residue inside the mixing box 1, which would waste resources and affect subsequent processing.
