Description

Technical Field

[0001] The present invention relates to the technical field of food safety detection equipment, and in particular to a multi-stage detection type food safety detection equipment. Background Art

[0002] Microbial testing is used in many fields, and food safety testing is the most widely used. Food is a product that affects people's physical and mental health. Food safety testing effectively promotes the development of the microbial industry, making product testing more convenient and faster, and the test results closer to the true value;

[0003] The current food safety testing equipment has been found to have at least the following technical problems:

[0004] First, the traditional detection device is complicated to operate when transferring the stirred sample to the detection test tube, which is easy to cause sample loss, especially for small or precious food samples.

[0005] Second, after grinding the food sample, the original equipment cannot achieve rapid and equal-ratio feeding of food and reactants, which affects the feeding efficiency and subsequent reaction effects.

[0006] Third, in previous food safety testing equipment, the food grinding and crushing process may have slow material feeding, resulting in long contact time between food debris and residual impurities inside the grinding equipment, increasing the risk of contamination. Summary of the invention

[0007] 1. Technical issues to be solved

[0008] In view of the deficiencies in the prior art, the present invention provides a multi-stage detection type food safety detection device to solve the above-mentioned technical problems.

[0009] (II) Technical solution

[0016] (III) Beneficial effects

[0017] 1. The present invention arranges the flip plate above the limit plate, so that after the food sample is ground, the food and the reactant can fall into the stirring barrel in equal proportions, which greatly improves the feeding efficiency of the food sample and the reactant. When the food sample and the reactant fall into the stirring chamber at the same time, the two can start mixing immediately. The instant mixing can ensure that the reaction is carried out under the best conditions, reduce the interference factors that may occur in the intermediate process, and improve the reaction efficiency.

[0018] Second: The food sample and the reactant in the present invention fall into the stirring chamber at the same time, which is conducive to achieving uniform mixing of the two under stirring. During the stirring process, the food sample and the reactant are in the same mixing environment from the beginning, and there is no situation where the local concentration is too high or too low. This uniform mixing can ensure that the reactant is in full contact with all the target components in the food sample, thereby making the reaction proceed more completely.

[0019] 3. The present invention cooperates with structures such as the drop tube, the connecting rod, and the extrusion collar so that the device can quickly place the sample into the test tube, which can effectively reduce the loss of food samples during the transfer and preparation process and prevent the loss of samples due to volatilization, splashing, or adhesion to the outside of the container wall. It is particularly important to reduce sample loss for some small or precious food samples, such as samples obtained from special ingredients or limited-production foods.

[0020] Fourth: The present invention provides a fast-flipping flip plate on the inner wall of the grinding barrel, so that food crumbs can be discharged quickly. When there may be some residual impurities or residual ingredients of the previous batch of food inside the grinding equipment, if the food crumbs are discharged quickly after grinding, it can reduce the contact time with these potential pollutants and reduce the possibility of contamination.

[0030] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0031] Example: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, in view of the problems existing in the prior art, the present invention provides a multi-stage detection type food safety detection equipment, a support frame 52 is fixedly installed on the detector 51, a mixing barrel 21 is fixedly installed on the support frame 52, including the detector 51, a detection turntable 23 is arranged on the upper end of the detector 51, at least six detection test tubes 22 are arranged on the detection turntable 23, a support ring 41 is fixedly installed on the upper end of the mixing barrel 21, a grinding barrel 31 is fixedly installed on the upper end of the support ring 41, a mixing bin is provided in the mixing barrel 21, a grinding bin is provided in the grinding barrel 31, a rotating rod 36 is rotatably installed through the grinding barrel 31, a flip plate 37 is fixedly installed on the circumferential surface of the rotating rod 36, and the flip plate 37 is installed through the bottom of the inner wall of the grinding barrel 31, a solvent box 45 is fixedly installed through the side end of the support ring 41, a connecting round rod 43 is slidably installed through the solvent box 45, a limit plate 42 is fixedly installed on the upper end of the connecting round rod 43, and a second spring 44 is fixedly installed between the limit plate 42 and the solvent box 45,

[0032] A servo motor 32 is fixedly installed on the upper end of the grinding barrel 31, and a rotating shaft 33 is fixedly installed on the lower end of the servo motor 32 through an output shaft. Three grinding and crushing components 34 are fixedly installed on the circumferential surface of the upper end of the rotating shaft 33 at equal intervals. Before testing the food, the device places the food inside the grinding barrel 31, and then turns on the switch of the servo motor 32, so that the servo motor 32 works to drive the rotating shaft 33 to rotate, and the rotating shaft 33 will drive the three groups of grinding and crushing components 34 to rotate, so that the food inside the grinding barrel 31 can be crushed and ground. After the food is crushed, the user can By rotating the rotating rod 36, the rotating rod 36 drives the flip plate 37 to rotate, and at this time the flip plate 37 will be separated from the bottom of the inner wall of the grinding barrel 31, so that the crushed and ground food crumbs in the grinding barrel 31 can fall into the interior of the mixing barrel 21. The present invention arranges a fast-flipping flip plate 37 on the inner wall of the grinding barrel 31 to make the food crumbs discharge quickly. When there may be some residual impurities or residual ingredients of the previous batch of food in the grinding equipment, if the food crumbs are discharged quickly after grinding, it can reduce the contact time with these potential pollutants and reduce the possibility of contamination.

[0033] The three grinding and crushing components 34 are all located inside the grinding barrel 31. Three stirring rods 24 are fixedly installed at equal intervals on the circumferential surface of the lower section of the rotating shaft 33. The three stirring rods 24 are all located inside the stirring barrel 21. During the process of the turning plate 37 moving down, the limit plate 42 will be squeezed, and the limit plate 42 will move downward. During the process of the limit plate 42 moving downward, the limit plate 42 will drive the connecting round rod 43 and the second blocking plate 46 to move downward. At this time, the second blocking plate 46 will be separated from the lower port of the solvent box 45. At this time, the liquid reactant inside the solvent box 45 will be discharged from the lower port of the solvent box 45. The food sample is ground and then flows out and then flows into the interior of the stirring barrel 21. At this time, the reactant and the food crumbs fall into the interior of the stirring barrel 21 at the same time. The present invention arranges the flip plate 37 above the limit plate 42, so that after the food sample is ground, the food and the reactant can fall into the stirring barrel 21 in equal proportions, which greatly improves the feeding efficiency of the food sample and the reactant. When the food sample and the reactant fall into the stirring chamber at the same time, the two can start mixing immediately. The instant mixing can ensure that the reaction is carried out under the best conditions, reduce the interference factors that may occur in the intermediate process, and improve the reaction efficiency.

[0034] The second spring 44 is sleeved on the circumferential surface of the connecting rod 43, and a second blocking plate 46 is fixedly installed at the lower end of the connecting rod 43. The second blocking plate 46 is slidably installed on the lower port of the solvent box 45. The bottom of the inner wall of the mixing barrel 21 passes through and is fixedly installed with a drop tube 16. A rectangular hole 14 is opened on the circumferential surface of the drop tube 16, and a first blocking plate 11 is slidably installed inside the drop tube 16. At this time, since the servo motor 32 is always working, the stirring rod 24 fixedly installed on the upper end of the rotating shaft 33 will also rotate, so that the reactant and food crumbs inside the mixing barrel 21 can be stirred and mixed, so that the food crumbs can react with the reactant to form a state that is more convenient for detection. The food sample and the reactant in the present invention fall into the stirring chamber at the same time, which is conducive to achieving uniform mixing of the two under stirring. During the stirring process, the food sample and the reactant are in the same mixing environment from the beginning, and there is no situation where the local concentration is too high or too low. This uniform mixing can ensure that the reactant is fully in contact with all target components in the food sample, so that the reaction is carried out more completely.

[0035] A push rod 12 is fixedly installed at the lower end of the first blocking plate 11, and a connecting rod 17 is fixedly installed at the lower end of the push rod 12. Extrusion collars 15 are fixedly installed on both sides of the connecting rod 17. The extrusion collar 15 is slidably sleeved on the outer surface of the drop tube 16. A first spring 13 is fixedly installed between the extrusion collar 15 and the mixing barrel 21. The detection test tube 22 is located at the lower end of the extrusion collar 15. After the mixing inside the mixing barrel 21 is completed, the user only needs to lift the detection test tube 22 upwards to let the detection test tube 22 apply pressure to the extrusion collar 15, so that the extrusion collar 15 moves upward, thereby driving the connecting rod 17, the push rod 12 and the first blocking plate 11 to move upward. At this time, the first blocking plate 11 will be pushed upwards to the inner wall of the mixing barrel 21, and a gap will be generated between the mixing barrel 21 and the drop tube 16. The mixture of reactants and food debris inside the mixing barrel 21 will fall from the drop tube 16 into the detection test tube 22. The test tube 22 is then put down, and the detector 51 is used to detect the mixture of reactants and food debris in the test tube 22. Since a first spring 13 is provided between the extrusion collar 15 and the bottom of the mixing barrel 21, the extrusion collar 15 will return to its original position after the test tube 22 is lowered, so that the first blocking plate 11 can continue to block the bottom of the mixing barrel 21. The present invention cooperates with the drop tube 16, the connecting rod 17 and the extrusion collar 15 and other structures, so that the device can quickly put the sample into the test tube, which can effectively reduce the loss of food samples during the transfer and preparation process, and can prevent the loss of samples due to volatilization, splashing or adhesion to the outside of the container wall. It is particularly important to reduce the loss of samples, especially for some small or precious food samples, such as samples obtained from special ingredients or limited-production foods.

[0036] Working principle:

[0037] In the first step, before the food is tested, the device places the food inside the grinding barrel 31, and then turns on the switch of the servo motor 32, so that the servo motor 32 works to drive the rotating shaft 33 to rotate, and the rotating shaft 33 will drive the three sets of grinding and crushing components 34 to rotate, so that the food inside the grinding barrel 31 can be crushed and ground. After the food is crushed, the user can rotate the rotating rod 36 to make the rotating rod 36 drive the flip plate 37 to rotate. At this time, the flip plate 37 will be separated from the bottom of the inner wall of the grinding barrel 31, so that the crushed and ground food crumbs in the grinding barrel 31 can fall into the interior of the mixing barrel 21. The present invention arranges a fast-flipping flip plate 37 on the inner wall of the grinding barrel 31, so that the food crumbs are discharged quickly. When there may be some residual impurities or residual components of the previous batch of food inside the grinding equipment, if the food crumbs are discharged quickly after grinding, the contact time with these potential pollutants can be reduced, thereby reducing the possibility of contamination.

[0038] In the second step, during the process of the flip plate 37 moving down, the limit plate 42 will be squeezed and the limit plate 42 will move downward. During the process of the limit plate 42 moving downward, the limit plate 42 will drive the connecting round rod 43 and the second blocking plate 46 to move downward. At this time, the second blocking plate 46 will be separated from the lower port of the solvent box 45. At this time, the liquid reactant located inside the solvent box 45 will flow out from the lower port of the solvent box 45 and then flow into the inside of the mixing barrel 21. At this time, the reactant will fall into the inside of the mixing barrel 21 at the same time as the food crumbs. The present invention arranges the flip plate 37 above the limit plate 42, so that after the food sample is ground, the food and the reactant can fall into the mixing barrel 21 in equal proportions, which greatly improves the efficiency of feeding the food sample and the reactant. When the food sample and the reactant fall into the mixing bin at the same time, the two can start mixing immediately. The instant mixing can ensure that the reaction is carried out under the best conditions, reduce the interference factors that may occur in the intermediate process, and improve the reaction efficiency.

[0039] In the third step, since the servo motor 32 is always working, the stirring rod 24 fixedly mounted on the upper end of the rotating shaft 33 will also rotate, so that the reactants and food crumbs inside the stirring barrel 21 can be stirred and mixed, so that the food crumbs can react with the reactants to form a state that is more convenient for detection. The food sample and the reactant in the present invention fall into the stirring bin at the same time, which is conducive to achieving uniform mixing of the two under stirring. During the stirring process, the food sample and the reactant are in the same mixing environment from the beginning, and there is no local concentration that is too high or too low. This uniform mixing can ensure that the reactant is in full contact with all target components in the food sample, so that the reaction can proceed more completely.

[0040] In the fourth step, after the stirring inside the mixing barrel 21 is completed, the user only needs to lift up the detection test tube 22, and let the detection test tube 22 apply pressure to the extrusion collar 15, so that the extrusion collar 15 moves upward, thereby driving the connecting rod 17, the push rod 12 and the first blocking plate 11 to move upward. At this time, the first blocking plate 11 will be pushed upward to the inner wall of the mixing barrel 21, and a gap will be generated between the mixing barrel 21 and the drop tube 16. The reactant and food debris mixture inside the mixing barrel 21 will fall from the drop tube 16 into the detection test tube 22, and then the detection test tube 22 is put down, and the detector 51 is used to detect the reactant and food debris mixture in the detection test tube 22. A first spring 13 is provided between the extrusion collar 15 and the bottom of the mixing barrel 21, so the extrusion collar 15 will return to its original position after the test tube 22 is moved downward, so that the first blocking plate 11 can continue to block the bottom of the mixing barrel 21. The present invention cooperates with the structures such as the drop tube 16, the connecting rod 17 and the extrusion collar 15, so that the device can quickly put the sample into the test tube, which can effectively reduce the loss of food samples during the transfer and preparation process and prevent the loss of samples due to volatilization, splashing or adhesion to the outside of the container wall. It is particularly important to reduce sample loss for some small or precious food samples, such as samples obtained from special ingredients or limited-production foods.

[0041] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
