Description

Technical Field

[0001] This utility model relates to the field of nitrosamine content detection technology, and in particular to a device for detecting nitrosamine content in food. Background Technology

[0002] Distillation is a key step in the process of detecting nitrosamine content in food; it acts as a bridge connecting sample processing and precise content determination, and is an essential path to obtaining accurate detection data.

[0003] However, traditional distillation apparatuses often face the problem of bumping during operation. Once bumping occurs, it not only causes the liquid to churn violently, but may even cause the liquid to rush uncontrollably into the condenser. This can damage the condenser and other equipment, increasing maintenance costs and replacement frequency. Furthermore, the abnormal flow of the liquid disrupts the stable distillation process, making it difficult to accurately control the composition and content of the distilled substances, which seriously affects the accuracy and reliability of nitrosamine content detection in food. In view of this, this paper proposes a device for detecting nitrosamine content in food that prevents bumping of the liquid in the distillation flask. Utility Model Content

[0004] The main purpose of this invention is to provide a device for detecting nitrosamine content in food, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A device for detecting nitrosamine content in food includes a split flask, which is mainly composed of a neck bottle and a pear-shaped bottle from top to bottom. The lower opening of the neck bottle is detachably installed at the upper opening of the pear-shaped bottle. A hemispherical foldable anti-boiling ceramic baffle is installed at the bottom of the spherical inner cavity of the pear-shaped bottle in the split flask.

[0007] The foldable anti-boiling ceramic baffle is mainly composed of a circular spherical ceramic sheet, a flexible connecting ring, and several fan-shaped spherical ceramic sheets. The inner ring of the flexible connecting ring is coaxially fixed to the outer ring of the circular spherical ceramic sheet. One side of several fan-shaped spherical ceramic sheets is evenly installed around the periphery of the flexible connecting ring. Several tiny through holes are densely arranged on both the circular spherical ceramic sheet and the fan-shaped spherical ceramic sheet, and several conical protrusions are densely fixed to both the inner and outer walls of the circular spherical ceramic sheet and the fan-shaped spherical ceramic sheet.

[0008] Preferably, the top of the neck bottle is fixedly connected to a vertical pipe and a branch pipe, the vertical pipe and the neck bottle are coaxially arranged, and a steam emission control element is coaxially installed inside the vertical pipe.

[0009] Preferably, the steam emission control element is mainly composed of a first circular plate and a second circular plate. The first circular plate is coaxially attached above the second circular plate. The first circular plate is provided with three first air holes, and the second circular plate is provided with three second air holes that are interleaved with the three first air holes on the first circular plate.

[0010] Preferably, a cylindrical rod is coaxially fixedly connected above the first circular plate, and a round rod is coaxially fixedly connected above the second circular plate, the round rod being coaxially rotatably installed inside the cylindrical rod.

[0011] Preferably, a sealing plug is coaxially fixedly installed at the top end of the cylindrical rod, and the sealing plug is inserted into the vertical tube.

[0012] Preferably, a knob is fixedly connected to the top end of the round rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes a foldable anti-bumping ceramic baffle design. The circular and fan-shaped spherical ceramic plates within the baffle are densely covered with through holes and conical protrusions. This allows intervention at the initial point of bubble formation—the bottom of the spherical inner cavity at the neck of the bottle—ensuring that the bubbles rupture upon contact with the conical protrusions during their ascent. This prevents excessive bubble accumulation and growth, effectively preventing bumping and ensuring a safe and stable distillation process. Simultaneously, the steam emission control element, through the structural design of the first and second circular plates and their interlocking and adjustable interconnected vents, along with components such as a knob, rod, and cylindrical rod, allows for precise manual control of the vent size, thereby adjusting the distillation rate. This precise distillation rate control, combined with the anti-bumping function, further optimizes the distillation process, enabling flexible adjustments to the distillation operation based on actual needs. This meets the distillation requirements for detecting nitrosamine content in food, ensuring detection accuracy and stability, and enhancing the practicality and reliability of the entire detection device.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] refer to Figures 1-6 As shown, a device for detecting nitrosamine content in food, reference Figures 1-6 As shown, a device for detecting nitrosamine content in food includes a split flask, a steam emission control element 5, and a foldable anti-bumping ceramic partition 6.

[0024] refer to Figure 1 , Figure 2 and Figure 3 The detachable flask consists of a neck flask 2 and a pear-shaped flask 1 from top to bottom. The two are connected by a clamp 3 to the lower opening of the neck flask 2 and the upper opening of the pear-shaped flask 1 in a detachable manner. The top of the neck flask 2 is fixedly connected to a vertical pipe 201 and a branch pipe 202. The vertical pipe 201 is coaxially arranged with the neck flask 2. The outer periphery of the foldable anti-boiling ceramic baffle 6 is fitted to the bottom of the spherical inner cavity of the pear-shaped flask 1.

[0025] refer to Figure 5 and Figure 6The foldable anti-boiling ceramic baffle 6 is mainly composed of a circular spherical ceramic plate 601, a flexible connecting ring 602, and several fan-shaped spherical ceramic plates 603. The flexible connecting ring 602 is mainly made of high-temperature silicone tubing or ceramic fiber fabric. The inner ring of the flexible connecting ring 602 is coaxially and fixedly connected to the outer ring of the circular spherical ceramic plate 601. Several fan-shaped spherical ceramic plates 603 are evenly and fixedly installed around the periphery of the flexible connecting ring 602. The gap between two adjacent fan-shaped spherical ceramic plates 603 is small. The circular spherical ceramic plate 601 and the fan-shaped spherical ceramic plates 603 are densely covered with tiny through holes 604, and both their inner and outer walls are densely fixed with conical protrusions 605. This structural design helps to... During distillation, it plays an anti-bumping role. When the liquid boils and produces bubbles, the bubbles rise to the conical protrusion 605. Due to the shape of the protrusion and the surface tension, the bubbles will break, preventing a large number of bubbles from accumulating and causing violent boiling. The through hole 604 allows the steam to pass through the partition smoothly and rise. At the same time, it allows the liquid to form a certain liquid layer thickness above the partition to increase stability. The diameter of the circular spherical ceramic plate 601 is smaller than the inner diameter of the opening at the top of the neck bottle 2. Several fan-shaped spherical ceramic plates 603 can be folded according to the flexible connecting ring 602, so that the foldable anti-bumping ceramic partition 6 can be quickly put into the neck bottle 2, or the foldable anti-bumping ceramic partition 6 can be taken out of the neck bottle 2.

[0026] refer to Figure 3 and Figure 4 The steam emission control element 5 is coaxially installed inside the vertical pipe 201. The steam emission control element 5 consists of a first circular plate 501 and a second circular plate 502. The first circular plate 501 is coaxially attached to the top of the second circular plate 502. The first circular plate 501 has three first air holes 506 that are evenly arranged in a circle with its central axis as the center. The second circular plate 502 has three second air holes 507 that are intersected with the first air holes 506. The three second air holes 507 are evenly arranged in a circle with the central axis of the second circular plate 502 as the center. When the first air holes 506 and the second air holes 507 are completely intersected, they are in a closed state.

[0027] A cylindrical rod 503 is coaxially fixedly connected above the first circular plate 501, and a circular rod 504 is coaxially fixedly connected above the second circular plate 502. The circular rod 504 is coaxially rotatably installed inside the cylindrical rod 503. A rubber sealing plug 4 is coaxially fixedly installed at the top of the cylindrical rod 503. The sealing plug 4 is inserted into the vertical tube 201. A knob 505 is fixedly connected to the top of the circular rod 504. Since the outer diameter of the first circular plate 501 and the second circular plate 502 is the same as the inner diameter of the lower end of the neck bottle body 2, when the first circular plate 501 and the second circular plate 502 are coaxially fitted and installed in the lower end cavity of the neck bottle body 2 and located below the branch tube 202, the outer walls of the first circular plate 501 and the second circular plate 502 are sealed with the inner wall of the neck bottle body 2.

[0028] In this invention, when a liquid begins to boil during heating, bubbles are generated from the bottom of the liquid. By placing a foldable anti-boiling ceramic baffle 6 at the bottom of the spherical inner cavity of the neck bottle body 2, the bubble can be intervened at the initial position of bubble generation. As the bubbles rise, they will come into contact with the conical protrusions 605 on the foldable anti-boiling ceramic baffle 6. Due to the presence of the protrusions, the bubbles will burst in these local areas, preventing excessive accumulation and growth of the bubbles, thereby preventing the occurrence of boiling.

[0029] By manually rotating the knob 505, the second circular plate 502 can be driven to rotate coaxially below the first circular plate 501 with the help of the round rod 504. This causes the first vent 506 and the second vent 507 to gradually change from an interlaced state to an aligned and connected state, thereby precisely controlling the size of the air passage between them, and thus adjusting the distillation rate. This achieves effective control of the distillation process, meets the requirements of distillation conditions in the detection of nitrosamine content in food, and ensures the accuracy and stability of the detection.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
