Description

Technical Field

[0001] This utility model belongs to the field of detection equipment technology, specifically relating to an astaxanthin nanoemulsion formulation screening device. Background Technology

[0002] Astaxanthin is mainly derived from Haematococcus pluvialis extract. Due to its oily state, its application in production and processing is significantly limited. Currently, astaxanthin can be formulated into water-in-oil (O / W) nanoemulsions using fat emulsification technology. These nanoemulsions have an average particle size of approximately 100-500 nm, classifying them as submicroemulsions. This expands their application range and improves their absorption and utilization rate. However, due to variations in the types and amounts of emulsifiers, surfactants, and co-solvents used in fat emulsification, there are significant differences in appearance and odor after dilution with water. Some nanoemulsions also exhibit slow dissolution rates and undissolved astaxanthin on the surface. During quality inspection, the state of the diluted astaxanthin nanoemulsion is recorded. Since recording at the same time after dilution is crucial for experimental accuracy, manual processing of only one sample at a time, followed by comparison of photos of different samples, is inconvenient. Currently, there is no dedicated equipment for screening astaxanthin nanoemulsion formulations.

[0003] Therefore, it is essential to develop a device that facilitates the simultaneous comparison of multiple samples, is more convenient to operate, and is specifically designed for screening astaxanthin nanoemulsion formulations. Utility Model Content

[0004] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an astaxanthin nanoemulsion formulation screening device.

[0005] The purpose of this utility model is achieved as follows: it includes a magnetic stirrer, a base, a crossbeam, support legs, a light box, a lifting device, an automatic dispensing head, and a transparent cup. The magnetic stirrer is a multi-position magnetic stirrer with the positions arranged in a row. Bases are provided on both sides of the magnetic stirrer, and slots are provided on the bases. Along the length of the crossbeam, several circular holes are provided on the crossbeam, each corresponding to a working position of the magnetic stirrer. Support legs are fixed at both ends of the crossbeam, and the support legs are inserted into the slots on the bases. The transparent cup passes through the circular holes from top to bottom, and the mouth of the transparent cup is held in the circular holes. The bottom of the transparent cup is placed on the corresponding working position of the magnetic stirrer. The light box is located behind the transparent cup, and a diffuser is provided on the front of the light box. An automatic dispensing head is provided above each transparent cup. The lifting device is connected to the automatic dispensing head, driving all the automatic dispensing heads to rise or fall synchronously.

[0006] Magnetic stirrers can be equipped with a master switch, meaning one switch controls the simultaneous start of all workstations, or they can be equipped with an independent switch for each workstation, allowing selection of the appropriate number of workstations to start as needed. The switch control method for multi-workstation magnetic stirrers is common knowledge in this field.

[0007] The lifting device can be a cylinder or other equipment; the automatic injection head can be equipped with components such as a solenoid valve and a flow meter to achieve quantitative automatic water injection, and the automatic injection head is connected to the pure water tank through a water pipe.

[0008] Preferably, the magnetic stirrer has 5 to 10 working positions, and the specific number of working positions can be flexibly selected as needed.

[0009] Preferably, the crossbar is provided with handles at both ends, which facilitates lifting the crossbar.

[0010] Preferably, the length of the light box is greater than the length of the magnetic stirrer, and the height of the light box is greater than the height of the transparent cup.

[0011] The lightbox can use a white background and white light, which is beneficial for observation.

[0012] Preferably, a camera device is provided in front of the transparent cup body, and the camera device is used to take pictures of the diluted sample inside the transparent cup body.

[0013] The beneficial effects of this invention are as follows: This invention can process multiple astaxanthin nanoemulsion formulation samples simultaneously, and can synchronously inject water and stir for dilution, which is convenient for inspectors to observe and compare at the same time. While improving the efficiency of astaxanthin nanoemulsion formulation screening experiments, it also ensures the accuracy of experimental results. The lifting and moving frame can move multiple cups at the same time, making the operation more convenient. The light box illuminates the back of all cups, making both manual observation and video recording more accurate. Attached Figure Description

The magnetic stirrer 1 is a multi-position magnetic stirrer with the working positions arranged in a row. Bases 2 are located on both sides of the magnetic stirrer 1, and slots are provided on the bases 2. Along the length of the crossbeam 3, several circular holes 9 are provided on the crossbeam 3, each corresponding to a working position of the magnetic stirrer 1. Support legs 4 are fixed at both ends of the crossbeam 3. 4. The transparent cup 8 is inserted into the slot on the base 2. The transparent cup 8 passes through the round hole 9 from top to bottom, and the mouth of the transparent cup 8 is stuck in the round hole 9. The bottom of the transparent cup 8 is placed on the working position corresponding to the magnetic stirrer 1. The light box 5 is located behind the transparent cup 8. The front of the light box 5 is provided with a diffuser. An automatic liquid injection head 7 is provided above the transparent cup 8. The lifting device 6 is connected to the automatic liquid injection head 7, which drives all the automatic liquid injection heads 7 to rise or fall synchronously. The crossbar 3 is provided with handles 10 at both ends. A camera device 11 is provided in front of the transparent cup 8.

[0022] Table 1. Screening results of astaxanthin nanoemulsion formulations

[0023]

[0024] The appearance of the nanoemulsion after being diluted 500 times is shown in Table 1. It can be seen from the appearance after dilution that the astaxanthin nanoemulsions of formulations 1 to 6 do not meet the requirements.

[0025] The working principle and process of this utility model are as follows: Before the experiment, equal amounts of astaxanthin nanoemulsion samples with different formulations are placed into different transparent cups 8, along with a stir bar. The transparent cups 8 are then placed into the round holes of the horizontal frame 3. The horizontal frame 3 and the transparent cups 8 are lifted as a whole and placed on the working position of the magnetic stirrer 1, ensuring that one working position corresponds to one transparent cup 8. The support legs 4 are inserted into the slots of the base 2 for positioning. The lifting device 6 is activated, and the automatic injection head 7 descends a certain distance, injecting a fixed amount of water into the transparent cups 8 through the automatic injection head 7. Afterward, the automatic injection head 7... Reset the container; start the magnetic stirrer 1, and the stir bar will rotate to mix the solution; after the solution stabilizes, compare and record the appearance of different formulations. During observation, the light box 5 illuminates the transparent cup 8 and the back of the solution, which facilitates observation and comparison of the differences between solutions in different transparent cups 8; after the experiment, lift the crossbeam 3 as a whole and remove the transparent cup 8 for subsequent cleaning; handle 10 makes it easy to lift the crossbeam 3; at this time, the next set of crossbeams 3 with transparent cups 8 waiting for the experiment can be placed directly on the magnetic stirrer 1, and the above process can be repeated to carry out the next set of dilution comparison experiments.
