Description

Technical Field

[0001] This utility model relates to the field of drip loss detection technology, and in particular to a portable rapid drip loss detector for pork. Background Technology

[0002] Pork is one of the most consumed meats globally, rich in high-quality protein, essential amino acids, B vitamins, and minerals (such as iron and zinc), making it an important source of nutrition. Its quality is affected by breed, feeding method, slaughtering process, and storage conditions. Among these factors, water retention (i.e., drip loss) is one of the key indicators for measuring meat quality, directly affecting the meat's taste, tenderness, processing performance, and economic value. Drip loss is the amount of water that naturally seeps out of the muscle under gravity after slaughter, and is usually expressed as a percentage of the initial mass of the meat sample.

[0003] The pork drip loss detector is designed for rapid and non-destructive assessment of pork water retention. It can quantitatively determine the drip loss rate within 1-3 minutes, replacing the traditional hanging weighing method (which requires 24-48 hours). It is suitable for slaughter lines, cold chain storage, market supervision and other scenarios. It uses a minimally invasive double-needle electrode (0.5mm in diameter) to pierce the meat sample and apply an alternating current (10kHz-1MHz) to measure the intercellular fluid conductivity and quantify the free water content. However, after the electrode is pierced, the outer wall is covered with oil stains, which can easily breed bacteria and contaminate the pork being tested. Manual cleaning is time-consuming and carries the risk of being punctured. Therefore, we propose a portable pork drip loss rapid detector to solve the existing problems. Utility Model Content

A water pump is located at the upper end of the mounting frame, and a flexible hose connected to the water pump is located at the lower end of the ultraviolet sterilizer.

[0006] Preferably, the mounting frame has symmetrically distributed crossbars inside, and guide plates are slidably sleeved on the outer walls of each crossbar. A movable rod, slidably installed inside the slide block, is disposed between the guide plates.

[0008] Preferably, a holding box is provided at the upper end of the base, and a display panel is provided at the front end of the detector. The display panel displays the test data, and the holding box stores the tested pork.

[0009] Preferably, the motor output end has a positioning hole inside, and the lower end of the cleaning cylinder is provided with a positioning sleeve. The positioning sleeve has a stroke hole inside, and a rod is slidably inserted into both the stroke hole and the positioning hole. After the rod is inserted into the positioning hole and the stroke hole, it locks and fixes the motor output shaft.

[0010] Preferably, each insertion rod has a side ring fitted onto its outer wall, and a spring fitted onto the outside of the insertion rod is provided between the side ring and the positioning sleeve. The elasticity of the spring provides elastic support to the insertion rod.

[0011] Preferably, a pull rod two is provided at one end of the insertion rod, and a rotating ring is rotatably mounted on the upper end of the cleaning cylinder, with a support ring provided on the inner wall of the rotating ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This invention uses an electrode of a detector to puncture pork, apply an alternating current of 10kHz-1MHz, measure the intercellular fluid conductivity, and quantify the free water content. Because it is positively correlated with drip loss, it enables the detection of pork water content. This method, which focuses on this aspect, provides a convenient way to detect drip loss in pork.

[0021] like Figures 1-5As shown, the present invention proposes a portable rapid detection instrument for dripping water loss in pork, including a mounting frame 5, a base 7, a cleaning cylinder 9, and a sliding base 14. The mounting frame 5 is provided on the upper end of the base 7, and the detector 2 is provided on the upper end of the mounting frame 5. A hydraulic rod 10 is provided inside the mounting frame 5, and a pressure plate 22 is provided at the lower end of the hydraulic rod 10. An electrode 23 is provided at the lower end of the pressure plate 22. A motor 8 with a rotating end is provided inside the upper end of the base 7. The cleaning cylinder 9 is provided above the output end of the motor 8. The inner wall of the cleaning cylinder 9 is provided with brushes 28 arranged in a ring array. A hydraulic rod 1 is provided on one side of the upper end of the detector 2. An ultraviolet sterilizer 11 is provided at the lower end of the hydraulic rod 1. Ultraviolet lamps 12 arranged in a ring array and corresponding to the upper part of the cleaning cylinder 9 are provided at the lower end of the ultraviolet sterilizer 11. A water pump 3 is provided on the upper end of the mounting frame 5, and a hose 13 connected to the water pump 3 is provided at the lower end of the ultraviolet sterilizer 11.

[0022] The mounting bracket 5 has symmetrically distributed crossbars 24 inside, and guide plates 21 are slidably sleeved on the outer walls of the crossbars 24. A movable rod 19 is slidably installed inside the slide block 14 between the guide plates 21.

[0023] The upper end of the slide block 14 is provided with symmetrically distributed support blocks 15. The support block 15 is rotatably mounted with a rotating shaft 17. The outer wall of the rotating shaft 17 is connected to a rotating sleeve 16. One end of the rotating sleeve 16 is provided with a pull rod 18, and the end of the pull rod 18 is provided with a handle 20.

[0024] A container 6 is provided on the upper part of the base 7, and a display panel 4 is provided on the front end of the detector 2;

[0025] The motor 8 has a positioning hole 32 inside its output end, and the cleaning cylinder 9 has a positioning sleeve 31 at its lower end. The positioning sleeve has a stroke hole 33 inside its positioning sleeve, and a rod 34 is slidably inserted into both the stroke hole 33 and the positioning hole 32.

[0026] All the outer walls of the insertion rod 34 are fitted with side rings 30, and a spring 25 fitted on the outside of the insertion rod 34 is provided between the side rings 30 and the positioning sleeve 31.

[0027] One end of the insertion rod 34 is provided with a pull rod 29, and a rotating ring 26 is rotatably installed on the upper end of the cleaning cylinder 9. A support ring 27 is provided on the inner wall of the rotating ring 26.

[0028] Based on the implementation steps of Example 1: The pork sample to be tested is placed in the holding box 6 of the base 7. The detection program is started through the display panel 4. The hydraulic rod 20 drives the pressure plate 22 to press down, so that the double needle electrode 23 is inserted into the meat sample in a minimally invasive manner (depth ≤ 5mm). The detector 2 applies an alternating current of 10kHz-1MHz. The electrode 23 senses the change in the conductivity of the intercellular fluid. The conductivity is positively correlated with the free water content. The built-in algorithm of the device converts the electrical signal into the drip loss rate.

[0029] After the test is completed, the hydraulic rod 10 raises the electrode 23 to a safe height. The operator pulls the lever 18 through the handle 20, so that the slide 14 moves laterally along the crossbar 24 to the top of the cleaning cylinder 9. The hydraulic rod 1 drives the ultraviolet sterilizer 11 to move down, and the support ring 27 lifts the electrode 23 to the center of the cleaning cylinder 9. The water pump 3 is started to inject clean water or weak alkaline cleaning solution into the cleaning cylinder 9. The motor 8 drives the cleaning cylinder 9 to rotate at 200-300 rpm. The inner wall annular brush 28 performs 360° mechanical brushing on the outer wall of the electrode 23 to remove oil stains and meat residue.

[0030] After cleaning, the waste liquid is discharged, and sterile distilled water is introduced into the ultraviolet sterilizer 11 through the hose 13 for rinsing. At the same time, the annular ultraviolet lamp 12 is activated with a wavelength of 254nm to irradiate and sterilize the surface of the electrode 23 for 5 minutes. The spring 25-supported insertion rod 34 structure ensures quick disassembly and assembly of the cleaning cylinder 9 and the output shaft of the motor 8, facilitating the periodic replacement of the brush 28.

[0031] Conductivity detection principle: The integrity of muscle cells affects the ion concentration in the intercellular fluid, and the drip loss rate is linearly correlated with conductivity (R0). 2 >0.95). When alternating current penetrates tissue, the more free water there is, the higher the ion mobility and the greater the conductivity value. The equipment accurately calculates the water content through calibration curves, mechanically brushes to remove organic residues, and ultraviolet light destroys the microbial DNA structure inside the cleaning cylinder 9 to sterilize the cleaning cylinder 9 and avoid cross-contamination. Compared with manual wiping, the cleaning efficiency is improved.

[0032] Integrating a hydraulic system and a folding slide 14, the equipment weighs ≤8kg, making it suitable for mobile inspection needs in slaughterhouses. The fully enclosed cleaning process reduces the risk of personnel contact. The ultraviolet lamps 12 are positioned high when not in use to prevent accidental contact. The electrodes 23, when reused, can easily spread pathogens such as Salmonella. This equipment employs a dual-mode treatment of cleaning and disinfection of the cleaning cylinder 9 to reduce the microbial load from 10... 4 CFU / cm 2 Reduced to <10 CFU / cm 2 It meets food contact material safety standards, shortens the time required for a single cleaning, and uses hydraulic drive to replace manual insertion and removal of electrodes 23, reducing the risk of punctures. The self-rotating design of the brush 28 avoids human hand contact with the cleaning liquid, improving safety and convenience.
