Description

Technical Field

[0001] The present invention relates to the technical field of trehalose emulsion preparation, and in particular to a trehalose emulsion preparation device and method. Background Art

[0002] Trehalose emulsion is an emulsion liquid product containing trehalose; trehalose is a natural sugar with special biological functions such as moisturizing, cold and drought resistance, heat and acid resistance, and has non-specific protective effects on biological macromolecules and organisms. Therefore, it is often used in the cosmetics, food, pharmaceutical and other industries. It can not only be used to protect the skin, but also to protect biological activity, improve drug stability and taste, etc.

[0003] At present, when preparing trehalose emulsion, due to its high viscosity, the trehalose emulsion is usually taken out by pouring, and then the trehalose emulsion adhering to the inner wall is scraped off; however, the pouring speed and the scraping of the inner wall of the equipment are completely controlled by the staff, which not only affects the efficiency of trehalose emulsion preparation, but also easily leads to pouring too fast or too slow. Among them, pouring too fast will lead to an increase of bubbles in the trehalose emulsion, affecting the stability of the trehalose emulsion; pouring too slowly may cause the trehalose emulsion to stratify, affecting its uniformity, and thus affecting the quality of the trehalose emulsion.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Embodiment 1:

[0037] Reference Figure 1-Figure 8, a trehalose emulsion preparation device, comprising a base 1, an emulsifying pot 2, and a connecting shaft 3 arranged on the emulsifying pot 2 and rotatably connected to the base 1, the emulsifying pot 2 is in a hollow hemispherical shape, and further comprising: a driving mechanism arranged on the base 1 and connected to the connecting shaft 3, for driving the emulsifying pot 2 to rotate along a predetermined trajectory, wherein a bracket 8 is fixedly connected to the emulsifying pot 2, a scraper 10 is rotatably connected to the inner side of the emulsifying pot 2 and the bracket 8, the scraper 10 matches and fits the shape of the inner wall of the emulsifying pot 2, the axis of rotation of the scraper 10 is on the same straight line as the axis of the emulsifying pot 2, an acceleration mechanism connected to the scraper 10 and the driving mechanism is arranged on the base 1, for driving the scraper 10 along the emulsifying pot The emulsifying pot 2 rotates in the opposite direction; the speed reduction mechanism arranged on the scraper 10 and the bracket 8 is used to detect the positional relationship between the scraper 10 and the trehalose emulsion and adjust the rotation speed of the scraper 10; the control mechanism arranged on the emulsifying pot 2 is used to detect the pouring speed of the trehalose emulsion and adjust the rotation speed of the emulsifying pot 2 and the scraper 10, and also includes a shearing emulsifier 9 arranged on the bracket 8, the shearing emulsifier 9 includes a motor, a stator and a rotor, the distance between the shearing emulsifier 9 and the bottom of the emulsifying pot 2 is greater than the size of the scraper 10, wherein the specific structure of the shearing emulsifier 9 can refer to the technical scheme in the prior art, which can be known by those skilled in the art and will not be elaborated here.

[0038] Reference Figure 1-Figure 3 The driving mechanism includes a driving motor 4 fixedly connected to the base 1, the output end of the driving motor 4 is connected to a rotating shaft 5, the rotating shaft 5 is fixedly connected to a driving gear 6, and a reduction gear 7 meshing with the driving gear 6 is fixedly connected to the connecting shaft 3 on one side.

[0039] The diameter ratio between the reduction gear 7 and the driving gear 6 is not limited here, and the staff can adjust it according to the actual situation. When the driving motor 4 drives the driving gear 6 to rotate, the reduction gear 7 can be driven to rotate in the reverse direction in a decelerated state, and the emulsification pot 2 can be driven to rotate, so that the trehalose emulsion after emulsification can be poured and collected.

[0040] Reference Figure 2-Figure 3 The acceleration mechanism includes a driven wheel 11 fixedly connected to the shaft end of the scraper 10 on the side close to the driving gear 6, a driving wheel 12 is fixedly connected to the rotating shaft 5, a limiting frame 13 is fixedly connected to the side of the base 1 close to the driving wheel 12, a first spring 14 is fixedly connected to the bottom of the limiting frame 13, a mounting block 15 slidably connected to the limiting frame 13 is fixedly connected to the top of the first spring 14, a tensioning wheel 16 is rotatably connected to the side of the mounting block 15 close to the driving wheel 12, and a belt 17 is sleeved between the driving wheel 12, the driven wheel 11 and the tensioning wheel 16.

[0041] It should be explained that, in the initial state, the scraper 10 is located on the side away from the pouring direction of the emulsifying pot 2. A limiting structure matching the scraper 10 can also be provided on the emulsifying pot 2 to prevent the scraper 10 from contacting the shearing emulsifier 9 when rotating to the initial position after the work is completed. During operation, the driving motor 4 drives the driving wheel 12 to rotate, and drives the scraper 10 to rotate in the opposite direction of the emulsifying pot 2 through the driven wheel 11 and the tensioning wheel 16, so as to scrape off the trehalose emulsion adhering to the inner wall of the emulsifying pot 2, and the rotation speed of the scraper 10 is greater than the rotation speed of the emulsifying pot 2, so as to shorten the time that the trehalose emulsion adheres to the inner wall of the emulsifying pot 2.

[0042] Among them, since the scraper 10 is rotating, the emulsifying pot 2 is also rotating, and under the action of the first spring 14, the belt 17 can always be closely fitted with the driving wheel 12 and the driven wheel 11 to ensure the stable rotation of the scraper 10. In addition, the belt 17 is usually made of a material with good wear resistance. Even if there is a large friction between the belt 17 and the driving wheel 12 and the driven wheel 11, it will not cause serious wear in a short time.

[0043] Reference Figure 4 , Figure 5 and Figure 8 The deceleration mechanism includes an installation cavity 22 opened on the side of the scraper 10 close to the emulsifying pot 2, a detection plate 23 is rotatably connected inside the installation cavity 22, a plurality of second springs 24 are fixedly connected between the detection plate 23 and the installation cavity 22, an arc-shaped seal 25 is fixedly connected to the bottom of the installation cavity 22, an arc-shaped support rod 26 slidably connected to the arc-shaped seal 25 is fixedly connected to the side of the detection plate 23 close to the installation cavity 22, a brake disc 27 slidably connected to the arc-shaped seal 25 is fixedly connected to the end of the arc-shaped support rod 26, wherein a sealed rotation mode is adopted between the detection plate 23 and the installation cavity 22, the centers of the arc-shaped seal 25 and the arc-shaped support rod 26 are located on the same straight line as the axis of the detection plate 23, and the brake disc 27 is tightly fitted to the inner wall of the arc-shaped seal 25.

[0044] It needs to be explained that there is hydraulic oil between the brake disc 27 and the arc-shaped seal 25. By conveying the hydraulic oil to the power-boosting pump, the hydraulic pressure can be amplified by the power-boosting pump, thereby driving the bidirectional hydraulic rod 19 to retract inward. Its working principle is similar to the working principle of the oil brake system of the vehicle. It is a conventional means in the prior art, so it is not elaborated. When the scraper 10 scrapes the inner wall of the emulsification pot 2, the increase in the contact amount between the scraper 10 and the trehalose emulsion increases the resistance encountered by the scraper 10 during rotation, thereby driving the detection plate 23 to rotate into the installation cavity 22, and at the same time, the brake disc 27 is driven to move through the arc-shaped support rod 26 (equivalent to stepping on the brake plate of the vehicle), reducing the rotation speed of the scraper 10, while ensuring that the inner wall of the emulsification pot 2 is scraped clean, the integrity of the trehalose emulsion can be ensured.

[0045] Reference Figure 4 and Figure 7 , and also includes a friction wheel 18 fixedly connected to the shaft end of the scraper 10 on the side away from the driven wheel 11, a two-way hydraulic rod 19 is fixedly connected to the side of the bracket 8 close to the friction wheel 18, the end of the two-way hydraulic rod 19 is fixedly connected to a fixing member 20, and a reduction block 21 is fixedly connected to the side where the fixing members 20 are close to each other, wherein, when hydraulic oil enters the two-way hydraulic rod 19, the two ends of the two-way hydraulic rod 19 are driven to retract inward, and the two-way hydraulic rod 19 is connected to the chamber between the bottom of the arc seal 25 and the brake disc 27 through a pipeline and a power pump, and the side where the reduction block 21 is close to each other is arranged in an arc shape, matching the friction wheel 18.

[0046] The bidirectional hydraulic rod 19 is a conventional means in the prior art. It can deliver hydraulic oil to both ends of the fixed part of the bidirectional hydraulic rod 19. A piston is set on the side of the output part of the bidirectional hydraulic rod 19 close to the fixed part, so that the output part of the bidirectional hydraulic rod 19 shrinks inward under the action of the hydraulic oil. It will not be elaborated here. When the contact area between the scraper 10 and the trehalose emulsion increases, the detection plate 23 will drive the brake disc 27 to move through the arc support rod 26, and the hydraulic pressure is amplified and delivered to the bidirectional hydraulic rod 19, driving the two ends of the bidirectional hydraulic rod 19 to shrink inward, and driving the deceleration block 21 to move to the side of the friction wheel 18, thereby increasing the resistance encountered by the scraper 10 during rotation, achieving a deceleration effect, so that the rotation speed of the scraper 10 matches the pouring speed of the trehalose emulsion, thereby reducing the influence of the scraper 10 on the pouring of the trehalose emulsion.

[0047] Reference Figure 4 and Figure 6 The control mechanism includes an extension block 28 symmetrically arranged on the outer wall of the emulsification pot 2, and a groove 29 is opened on the side of the extension block 28 close to the emulsification pot 2. A rotating member 30 is rotatably connected inside the groove 29, and multiple groups of sealed variable resistors 31 are fixedly connected inside the groove 29. A third spring 32 is sleeved on the sealed variable resistor 31, wherein the extension block 28 is close to the opening of the emulsification pot 2, the rotating member 30 is inclined in the direction of pouring the algae emulsion, and a sealed rotation method is adopted between the rotating member 30 and the groove 29. The sealed variable resistor 31 is electrically connected to the driving motor 4. When the sealed variable resistor 31 contracts, its resistance increases, and the gas in the sealed variable resistor 31 is compressed. When the sealed variable resistor 31 extends, its resistance decreases. The sealed variable resistor 31 is connected to the chamber on the side of the arc sealing member 25 close to the arc support rod 26 through a pipeline.

[0048] It should be explained that, since the emulsifying pot 2 is hemispherical, when pouring, the trehalose emulsion will first drip from the bottom of the tilted emulsifying pot 2. If the pouring speed is accelerated, the pouring width of the trehalose emulsion increases, and the distance between the two sets of rotating parts 30 is slightly smaller than the distance of the optimal pouring width of the trehalose emulsion, so that the optimal pouring speed is achieved when part of the trehalose emulsion flows through the rotating part 30; and if the pouring speed of the trehalose emulsion is too fast, the amount of trehalose emulsion flowing through the rotating part 30 increases, and the pressure on the rotating part 30 increases, so that the pouring speed of the trehalose emulsion can be detected, and the rotation of the driving motor 4 is adjusted through the sealing variable resistor 31 to slow down the rotation speed of the emulsifying pot 2 and the rotation speed of the scraper 10. If the pouring speed of the trehalose emulsion is too slow, the working principle is the same as above, and the process is reversed until the trehalose emulsion can be poured at a stable speed, thereby avoiding the phenomenon of increased bubbles and stratification in the trehalose emulsion, thereby improving the quality of the trehalose emulsion.

[0049] Embodiment 2:

[0050] A method for preparing a trehalose emulsion comprises the following steps:

[0051] Step 1: Place the raw materials in the equipment according to the proportion and stir and emulsify them;

[0052] Step 2: After emulsification is completed, pour the trehalose emulsion and scrape off the emulsion adhering to the inner wall of the equipment;

[0053] Step 3: During the pouring process, the pouring speed and scraping speed of the trehalose emulsion are tested;

[0054] Step 4: The pouring speed of the trehalose emulsion is controlled by adjusting the scraping speed and the tilting speed of the equipment to ensure that the trehalose emulsion is poured stably.

[0055] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
