Microencapsulation technology has been applied to various fields, including medicine, pesticides, perfumery, coatings, food science, and cosmetics.

[0003] After checking the publication number: CN215428948U, a drip tray assembly for microcapsule preparation is disclosed. This technology discloses "a drip tray assembly for microcapsule preparation, which relates to the field of microcapsule manufacturing technology. The utility model includes a cylinder; the two ends of the cylinder are respectively connected to an upper end cover and a lower end cover; the interior of the cylinder is divided into a first liquid chamber, a second liquid chamber and a continuous phase body chamber by an upper partition and a lower partition; the lower end cover is connected to a plurality of injection pipes; the upper partition and the lower partition are fixed with a continuous phase injection pipe; the lower end of the continuous phase injection pipe is connected to the connecting The continuous phase body cavity is connected; a liquid inlet pipe is provided in the continuous phase injection tube; the lower end of the liquid inlet pipe is connected to the second liquid cavity; the lower partition is connected to an outer tube, the outer tube extends into the injection tube, and the upper end is connected to the second liquid cavity; the upper partition is connected to an inner tube, the inner tube extends into the outer tube and is connected to the first liquid cavity. The technical solution has the following technical effects: "By providing multiple pairs of outer tubes and inner tubes, the problem of low production efficiency in the existing production is solved; the continuous phase fluid injected through the injection tube realizes the control of microcapsule particle size, solving the problem of poor quality of microcapsule preparation in the existing microcapsule";

[0004] For drip trays that rely entirely on gravity, initially, due to the abundance of material in the tray, they often exhibit a relatively fast dripping rate. However, as the material gradually decreases and approaches exhaustion, the dripping rate slows significantly. This phenomenon is primarily due to the fact that gravity's effect on the material becomes less efficient as the amount of material decreases. This, combined with the possible effects of surface tension, viscosity changes, and clogged drip holes, results in significant variations in the final microcapsules, making quality assurance difficult.

[0005] In response to the shortcomings of the existing technology, the utility model provides a drip tray assembly for preparing microcapsules, which monitors the inside of the first liquid collecting tank and the second liquid collecting tank respectively through a first liquid level sensor and a second liquid level sensor. When the dripping liquid inside the first liquid collecting tank and the second liquid collecting tank is lower than the first liquid level sensor and the second liquid level sensor, the air intake of the first air inlet pipe and the second air inlet pipe can be controlled by increasing the air pressure to maintain a stable dripping rate, thereby avoiding the characteristic of slowing down the dripping speed due to the reduction of dripping inside the first liquid collecting tank and the second liquid collecting tank when no dripping material enters.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-4 The utility model provides a technical solution of a drip tray assembly for preparing microcapsules: a drip tray assembly for preparing microcapsules, comprising a drip tray 1, a drip mechanism 2 provided on the drip tray 1 and used to form dripping liquid, the drip mechanism 2 comprising:

[0026] The dispersed phase liquid assembly 21 includes a circular plate 211 fixed to the lower end of the drip tray 1, a plurality of first liquid collecting troughs 212 fixed to the top of the circular plate 211 and distributed in a circumferential manner, a first dripping pipe 213 fixed to the bottom of the first liquid collecting troughs 212, a first multi-way pipe 214 provided in the middle of the circular plate 211, and the first multi-way pipe 214 is connected to the plurality of first liquid collecting troughs 212 through pipes, and a first liquid level sensor 217 is installed on one of the first liquid collecting troughs 212;

[0027] The core liquid assembly 22 includes a ring plate 221 fixed to the upper end of the drip tray 1, a plurality of circumferentially distributed second liquid collecting troughs 222 fixed to the bottom of the ring plate 221, and a second dripping pipe 223 fixed to the bottom of the second liquid collecting trough 222. The second dripping pipe 223 extends into the interior of the first dripping pipe 213, and a second liquid level sensor 227 is installed on one of the second liquid collecting troughs 222.

[0028] The regulating assembly 23 includes a plurality of dripping heads 231 fixed on the bottom of the circular plate 211 and distributed around the circumference.

[0029] In this embodiment, the inner core liquid in the second collecting tank 222 drips out through the second dripping tube 223, and the dispersed phase liquid in the first collecting tank 212 drips out through the first dripping tube 213. After dripping out, the dispersed phase liquid coats the inner core liquid and, under the shearing action of the continuous phase flow, causes the microcapsules to disperse rapidly, thereby facilitating improving the overall preparation efficiency. Moreover, the first liquid level sensor 217 and the second liquid level sensor 227 are used to monitor the inside of the first collecting tank 212 and the second collecting tank 222 respectively. When the dripping liquid inside the first collecting tank 212 and the second collecting tank 222 is lower than the first liquid level sensor 217 and the second liquid level sensor 227, the air intake of the first air inlet pipe 216 and the second air inlet pipe 226 can be controlled by increasing the air pressure to maintain a stable dripping rate, thereby avoiding the dripping speed slowing down due to the reduction of dripping material inside the first collecting tank 212 and the second collecting tank 222 when no dripping material enters.

[0030] Specifically, the dispersed phase liquid component 21 further includes a first liquid adding pipe 215 and a first air inlet pipe 216 connected to the upper end of the first multi-way pipe 214 through a tee pipe, and the first liquid adding pipe 215 and the first air inlet pipe 216 both extend to the outside of the drip tray 1.

[0031] In this embodiment, the dispersed phase liquid can be injected through the first liquid adding pipe 215 , and compressed air can be injected through the first air inlet pipe 216 at the same time, so that the dispersed phase liquid enters the first liquid collecting tank 212 through the first multi-way pipe 214 .

[0032] Specifically, the inner core liquid assembly 22 also includes a second multi-way pipe 224 arranged in the middle of the ring plate 221, and the second multi-way pipe 224 is connected to several second liquid collecting tanks 222 through pipes, and the upper end of the second multi-way pipe 224 is respectively connected to the second liquid adding pipe 225 and the second air inlet pipe 226 through a three-way pipe, and the second liquid adding pipe 225 and the second air inlet pipe 226 both extend to the outside of the drip tray 1.

[0033] In this embodiment, the core liquid can be injected through the second liquid adding pipe 225 and compressed air can be injected through the second air inlet pipe 226 at the same time, so that the core liquid enters the second liquid collecting tank 222 through the second multi-way pipe 224.

[0034] Specifically, the adjustment assembly 23 further includes a threaded cover 232 threadedly mounted on the lower end of the dripping head 231 , a dripping port 233 defined within the threaded cover 232 , and a plug 234 fixed within the dripping port 233 .

[0035] In this embodiment, the threaded cover 232 with plugs 234 of different specifications can be replaced so that after the threaded cover 232 is installed at the lower end of the dripping head 231, the bottom of the first dripping tube 213 and a part of the bottom of the second dripping tube 223 can be blocked by the plug 234, thereby controlling the dripping speed.

[0036] Specifically, the dripping mechanism 2 further includes a mounting frame 24 fixed to the outer wall of one of the dripping heads 231 , and a photoelectric sensor 25 installed at the lower end of the mounting frame 24 .

[0037] In this embodiment, when a droplet passes through the optical path of the photoelectric sensor 25, it blocks the light, causing the sensor output signal to change. By measuring the number of signal changes per unit time, the droplet velocity can be monitored.

[0038] The working principle and usage process of the present invention are as follows: first, dispersed phase liquid can be injected through the first liquid adding pipe 215, and compressed air can be injected through the first air inlet pipe 216 at the same time, so that the dispersed phase liquid can enter the first liquid collecting tank 212 through the first multi-way pipe 214; core liquid can be injected through the second liquid adding pipe 225, and compressed air can be injected through the second air inlet pipe 226 at the same time, so that the core liquid can enter the second liquid collecting tank 222 through the second multi-way pipe 224;

[0039] Then, the inner core liquid in the second collecting tank 222 drips out through the second dripping tube 223, and the dispersed phase liquid in the first collecting tank 212 drips out through the first dripping tube 213. After dripping out, the dispersed phase liquid coats the inner core liquid and, under the shearing action of the continuous phase flow, causes the microcapsules to disperse rapidly, thereby facilitating improving the overall preparation efficiency. Moreover, the first liquid level sensor 217 and the second liquid level sensor 227 are used to monitor the inside of the first collecting tank 212 and the second collecting tank 222 respectively. When the dripping liquid inside the first collecting tank 212 and the second collecting tank 222 is lower than the first liquid level sensor 217 and the second liquid level sensor 227, the air intake of the first air inlet pipe 216 and the second air inlet pipe 226 can be controlled by increasing the air pressure to maintain a stable dripping rate, thereby avoiding the dripping speed slowing down due to the reduction of dripping material inside the first collecting tank 212 and the second collecting tank 222 when no dripping material enters.
