Description

Technical Field

[0001] This utility model relates to the field of sterilization detection technology, specifically to a crawling physical disinfection effect indicator device for tableware. Background Technology

[0002] In the catering service and related industries, the hygiene and safety of complete sets of tableware are directly related to the health of consumers. The handling process must strictly follow national standards, covering key processes such as washing, cleaning, disinfection and packaging. Standardized operation at each stage is the core to ensure the hygiene and quality of the final product.

[0003] However, the current standardized process of "disinfection before packaging" has the following shortcomings in actual operation: On the one hand, if the entire process is not completed in a professional purification and disinfection workshop, the complete set of tableware (including disposable tableware) is prone to secondary contamination due to microorganisms and impurities in the environment when it enters the packaging stage after disinfection, making it difficult to effectively guarantee the hygiene quality of the final product; on the other hand, for tableware that has been disinfected by high-temperature steam or infrared dry heat, the industry generally adopts the method of periodic sampling and testing for quality monitoring. This method can only conduct intermittent assessments of detergent residues and microbial limits, which is a passive and lagging monitoring mode that cannot comprehensively and in real time reflect the disinfection quality of each product leaving the factory. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a crawling physical disinfection effect indicator for tableware, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A crawling physical disinfection effect indicator for tableware, with a base plate whose surface has a receiving groove;

[0007] A hot melt sheet, which is embedded in the bottom of one end of a receiving groove;

[0008] The absorbent strip is embedded inside the receiving groove and covers the top of the hot melt sheet;

[0009] A breathable membrane is used to cover the surface of the base plate, and the surface area of ​​the breathable membrane is larger than the cross-sectional area of ​​the receiving groove.

[0010] A cover plate is placed on the base plate, and an observation window is provided on the surface of the cover plate opposite to the water absorption strip.

[0011] Furthermore, one end of the receiving tank is a first tank body, and the other end of the receiving tank is a second tank body. The first tank body and the second tank body are connected as one unit. The hot melt sheet is embedded in the first tank body, and one end of the water-absorbing strip is embedded in the first tank body and the other end is embedded in the second tank body.

[0013] Furthermore, an annular frame is provided at the bottom edge of the cover plate, which is engaged with the outer wall of the base plate, and the surface area of ​​the breathable membrane is the same as that of the base plate.

[0014] Furthermore, both the cover plate and the bottom plate are rectangular, and a U-shaped enclosure frame is provided at the outer edge of the bottom surface of the cover plate, with the open end of the enclosure frame horizontally inserted into the outside of the bottom plate.

[0015] Furthermore, a rotating shaft is rotatably installed at the center of the opening end of the cover plate, and a locking plate is provided at the outer end of the rotating shaft. When the locking plate is rotated to the vertical position, the locking plate abuts against and stops the ends of the cover plate and the bottom plate.

[0016] Furthermore, the surface of the cover plate is provided with ventilation holes.

[0017] This utility model provides a crawling-type physical disinfection effect indicator for tableware. Compared with the prior art, it has the following advantages:

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0031] Combination Figure 1 As shown, the crawling physical disinfection effect indicator device for tableware provided by this utility model includes a base plate 500 with a receiving groove on its surface; a hot-melt sheet 400 embedded in the bottom of one end of the receiving groove; a water-absorbing strip 300 embedded in the inside of the receiving groove, covering the top of the hot-melt sheet 400; a breathable membrane 200 covering the surface of the base plate 500, the surface area of ​​the breathable membrane 200 being larger than the cross-sectional area of ​​the receiving groove; and a cover plate 100 covering the base plate 500, the surface of the cover plate 100 having an observation window 110 arranged opposite to the water-absorbing strip 300.

[0032] Specifically, the hot-melt sheet is in the form of a sheet, disc, or other irregular shape. The formula of the hot-melt sheet is: 60-73% main ingredient, 16-19% excipients, 6-9% binder, 9-12% flow aid, and the balance being food coloring. The main ingredient of the moisture-absorbing sheet is any one of α-D glucose, maltose, and sucrose; the excipient is polyethylene glycol 6000; the binder is any one of sodium carboxymethyl cellulose, copovidone, and sorbitol; and the flow aid is any one of fumed silica, sodium stearate fumarate, starch-based flow aid, and glyceryl behenate.

[0033] Specifically, the absorbent sheet is made of filter paper or absorbent paper.

[0034] In this embodiment, the device shape includes, but is not limited to, rectangle, trapezoid, rhombus, square, circle, and ellipse.

[0035] In this embodiment, one end of the receiving groove is a first groove 510, and the other end of the receiving groove is a second groove 520. The first groove 510 and the second groove 520 are connected as one unit. The hot melt sheet 400 is embedded in the first groove 510, and one end of the water-absorbing strip 300 is embedded in the first groove 510 and the other end is embedded in the second groove 520.

[0037] During assembly in this embodiment:

[0038] Place the hot melt sheet 400 in the first tank 510, and place the absorbent strip 300 in the second tank 520 and cover the hot melt sheet 400. Because there is adhesive on the surface of the aluminum foil tape, the hot melt sheet 400 and the absorbent strip 300 are stuck together. Then, attach the breathable membrane 200 to the surface of the aluminum foil tape. The breathable membrane 200 is attached to the aluminum foil tape. Finally, attach the label paper to cover the aluminum foil tape. The absorbent strip 300 is arranged opposite to the observation window 110 to obtain the indicator.

[0040] Disposable tableware is placed into a sterilization device (high-temperature steam sterilization or infrared dry heat sterilization). After a certain period of sterilization, the hot melt sheet 400 will dissolve, and the dissolved liquid will be absorbed by the absorbent strip 300. The absorbent part of the absorbent strip 300 will change color to a certain extent.

[0041] When using the tableware, users can observe the liquid absorption status of the absorbent strip 300 through the observation window 110 to understand the disinfection status of the tableware.

[0042] For example, the disinfection status can be determined in two ways:

[0043] Method 1: When the user sees that the absorbent strip in the area of ​​the observation window is fully soaked with liquid, it indicates that the disinfection is qualified.

[0044] Method 2: The observation window has scales and text on both sides to indicate the qualified area and the qualified area. Example 2
