DETAILED DESCRIPTION
[0036] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0037] like Figures 1 to 5 As shown, a portable device for quickly detecting whether harmful substances in starch intestines exceed the standard includes a food processing titration instrument 1 and an integrated test paper board 2:
[0038] The food processing titration instrument 1 comprises a push-type small-aperture pipe 101 and a hollow cylinder 102. The outer surface of the bottom end of the push-type small-aperture pipe 101 is fixedly connected with a piston 103. The outer surface of the top end of the push-type small-aperture pipe 101 is fixedly connected with a circular ring-shaped pressing thin plate 104. The pressing thin plate 104 facilitates the operator to press the operation by hand. The push-type small-aperture pipe 101 facilitates the connection with the outside atmospheric pressure. The outer surface of the top end of the hollow cylinder 102 is fixedly connected with a piston 103. There is a lever plate 105, which is convenient for the operator to use his hands to leverage when pressing. A cutting steel mesh 106 and a filter 107 are fixedly installed on the inner wall of the hollow cylinder 102. A solvent is arranged inside the hollow cylinder 102, and the solvent is located below the cutting steel mesh 106. A conical soft head 108 is fixedly connected to the bottom end of the hollow cylinder 102. The conical soft head 108 is adapted to the size of the hollow cylinder 102, and a dropper 109 is fixedly connected to the bottom end of the conical soft head 108.
[0039] The integrated test paper board 2 includes four parallel test areas 201, each of which has a card slot 202 on one side, each of which has a test paper 203 inside, and each of which has a standard colorimetric card 204 on the four test areas 201. By observing the color comparison between the test paper 203 and the standard colorimetric card 204, it can be understood whether the harmful substances in the starch intestine exceed the standard.
[0040] As an optional technical solution of the utility model, a plastic connecting block 3 is fixedly connected to the outer surface of the hollow cylinder 102, and the plastic connecting block 3 is connected to a dropper cover 4 through a connecting rope. The dropper cover 4 is adapted to the size of the dropper 109. The dropper cover 4 is connected to the hollow cylinder 102 into an integrated structure through the plastic connecting block 3 and the connecting rope, thereby avoiding the loss of the dropper cover 4. When the dropper 109 is not in use, the dropper cover 4 is sleeved on the outer surface of the dropper 109, and the dropper 109 can be sealed through the dropper cover 4.
[0041] As an optional technical solution of the present invention, a plastic film is provided above the hollow cylinder 102 to seal the end of the hollow cylinder 102. The plastic film can prevent external air from entering the interior of the hollow cylinder 102 when no detection is performed, thereby avoiding the influence of the external hollowness on the reagent inside the hollow cylinder 102, thereby ensuring the accuracy of subsequent detection.
[0042] As an optional technical solution of the present invention, the diameter of the piston 103 is matched with the diameter of the hollow cylinder 102, ensuring that the piston 103 fits tightly with the inner wall of the hollow cylinder 102 while moving smoothly.
[0043] As an optional technical solution of the present invention, the filter screen 107 is located above the conical soft head 108, and the filter screen 107 is located below the cutting steel mesh 106. The mesh diameter of the filter screen 107 is smaller than the mesh diameter of the cutting steel mesh 106. The chopped starch sausage can be filtered through the filter screen 107, thereby achieving the effect of solid-liquid separation.
[0044] As an optional technical solution of the present invention, the standard colorimetric card 204 corresponds to the position of the card slot 202, and the substances detected by the four test papers 203 are different. The detection objects of the four test papers 203 are nitrite, oil price, oil peroxide value and borax in starch intestine. Similarly, the four standard colorimetric cards 204 are colorimetric cards of nitrite, oil price, oil peroxide value and borax respectively.
[0045] As an optional technical solution of the present invention, the conical soft head 108 and the dropper 109 are both made of rubber. The conical soft head 108 and the dropper 109 can conveniently squeeze the reagent inside the conical soft head 108 and make the reagent drip out in the form of water droplets, so that the reagent can better drip into the interior of the card slot 202 and contact the test paper 203.
[0046] A portable device for quickly detecting whether harmful substances in starch intestines exceed the standard. The working principle is as follows:
[0047] 1) Tear off the plastic film that is sealed above the hollow cylinder 102;
[0048] 2) placing the starch sausage sample inside the hollow cylinder 102 and placing the starch sausage sample on the cutting steel mesh 106;
[0049] 3) placing the piston 103 inside the hollow cylinder 102, and pressing the thin plate 104 to make the press-type small-aperture pipe 101 drive the piston 103 to move downward and squeeze the starch intestine sample, and at this time, the starch intestine sample is broken by the cutting steel mesh 106 and the broken starch intestine sample falls into the solvent below the cutting steel mesh 106;
[0050] 4) Shake the hollow cylinder 102 to allow the solvent to fully contact the cut starch intestines;
[0051] 5) Remove the dropper cap 4 on the dropper 109, squeeze the conical soft head 108 by hand to make the liquid drip out through the dropper 109 drop by drop, and make the liquid drip into the inside of the four card slots 202 respectively and make the test paper 203 contact, and let it stand for 5 minutes;
[0052] 6) After standing for 5 minutes, observe the color of the test paper through the card slot 202 and compare it with the standard colorimetric card 204 to determine whether the harmful substances in the starch intestine exceed the standard.
[0053] To sum up, the portable device for quickly detecting whether the harmful substances in starch intestine exceed the standard has the advantages of easy operation and comprehensive detection. Through simple pressing and titration actions, consumers can easily complete the detection of nitrite, oil price, oil peroxide value and borax content in starch intestine. There is no need for complicated grinding, extraction and other steps, which greatly reduces the difficulty of operation and increases the comprehensiveness of detection. Rapid detection can obtain test results in a short time, which meets the needs of consumers for instant detection and avoids the trouble of long waiting. The device is small in size and portable. The device is small in size and easy to carry, making on-site detection more convenient and cost-effective. It is made of low-cost materials, which reduces the cost of detection equipment, is in line with the consumption level of more consumers, and is conducive to the popularization and promotion of technology. Accuracy and reliability are integrated through test strips The color change display of the board 2 can accurately detect whether the content of nitrite, oil price, oil peroxide value and borax in the starch sausage exceeds the standard, whether the food is edible, and provide consumers with a reliable reference basis. An integrated test paper board 2 is used, and four detection test papers 203 are respectively placed in the integrated test paper board 2 with a rectangular shape, and the test papers 203 are placed in the four card slots 202 of the integrated test paper board 2, so that the integrated test paper board is more convenient to carry and has a wide range of applications. The detection device of the present invention is not only suitable for the detection of starch sausage, but theoretically can also be slightly adjusted for rapid detection of other similar foods. Therefore, it has a wider range of applications and promotes food industry standardization.
