Description

Technical Field

[0001] The present invention relates to the technical field of food production, in particular to a food microorganism detection device and a detection method thereof. Background Art

[0002] Food refers to all kinds of finished products and raw materials for human consumption or drinking. By testing the content and types of microorganisms in food, potential sources of microbial contamination can be discovered and controlled in a timely manner, thereby ensuring the sanitary quality of food and the health and safety of consumers. There are many types of food, mainly including grains, fruits and vegetables, meat, and processed foods;

[0003] As a common processed food, biscuits are loved by consumers of all ages and groups because of their diverse flavors, convenient eating methods and long shelf life. Due to their wide audience, their safety is directly related to the health of many consumers. Microbial contamination is one of the main reasons for the unsafety of biscuits. Therefore, microbial testing of biscuits is very important. Through testing, harmful microorganisms can be discovered and controlled in time to prevent them from causing harm to human health.

[0004] In the production process of biscuits, the detection of microorganisms requires the suspension to be inoculated into different types of culture media, such as beef extract peptone culture medium (for bacterial culture), bacterial culture medium (for the culture of specific bacteria) and fungal culture medium (for the culture of molds and yeasts). At this time, multiple suspensions need to be prepared. Secondly, in the long-term production of biscuits in the factory, different production batches of biscuits need to be sampled and tested. The sampling method by staff in batches has a low degree of automation and cannot improve efficiency. In addition, cross-contamination of biscuit flora is easily generated during manual sampling, which will affect the determination of biscuit detection results.

[0041] See also Figure 1-Figure 8As shown, the present embodiment provides a food microorganism detection device, comprising a support frame 1, a transmission chamber 11 is fixedly connected to the inner side of the upper end of the support frame 1, a No. 1 conveyor belt 12, a No. 2 conveyor belt 13 and a No. 3 conveyor belt 14 for conveying biscuits are arranged on the inner side of the transmission chamber 11, a pressing roller 16 for sample preparation is arranged above the No. 3 conveyor belt 14, a workpiece component 23 for sampling is arranged on one side of the No. 3 conveyor belt 14, and a detection component 4 for preparing a suspension for detection is arranged on one side of the workpiece component 23, wherein: the conveyance of the No. 3 conveyor belt 14 is utilized, the pressing roller 16 is utilized to complete the sample preparation of the biscuit sample, and the workpiece component 23 and the detection component 4 are utilized to complete the sampling and the preparation of various suspensions.

[0042] like Figure 2-Figure 5 As shown, the outer wall of one end of the rotating wheel of the No. 1 conveyor belt 12 is sleeved with a No. 1 belt 121, and the other end of the No. 1 belt 121 is sleeved on one end of the rotating wheel of the No. 3 conveyor belt 14. The No. 1 conveyor belt 12 is fixedly connected to the No. 1 gear 122 at the end of the rotating wheel on the side away from the No. 1 belt 121. The No. 2 conveyor belt 13 is fixedly connected to the rotating wheel end with a No. 2 gear 131, and the No. 2 gear 131 is meshed with the No. 1 gear 122. An extrusion roller 15 is arranged on one side of the outer wall of the No. 2 conveyor belt 13, and the two ends of the extrusion roller 15 are fixedly connected with the No. 3 gear 151. Gear No. 151 is meshedly connected with gear No. 122, and a grid shell 161 is fixedly connected to the outer wall of the pressing roller 16. The grid shell 161 is a square grid of regular size, and one column of grids in the grid shell 161 is smaller than the normal size. A regular conveyor belt 17 is arranged below the No. 3 conveyor belt 14. The regular conveyor belt 17 is distributed in sections. The regular conveyor belt 17 is fixedly connected to the inner side of the support frame 1 through a guard plate. A plurality of No. 1 regular plates 171 are fixedly connected to the inner side of the guard plate. The No. 1 regular plates 171 are distributed in an array and penetrate the regular conveyor belt 17.

[0043] like Figure 4-Figure 5 As shown, a triangular column 2 is fixedly connected to the inner side of the guard plate on one side of the regular conveyor belt 17, a No. 2 regular plate 21 is fixedly connected to the top of the triangular hypotenuse of the triangular column 2, a fixed plate 211 is fixedly connected to the bottom inner wall of the triangular column 2, a servo motor 22 is fixedly connected to the outer wall of one side of the triangular column 2, and a No. 1 rotating rod 221 is fixedly connected to the output end of the servo motor 22, and a plurality of I-shaped components 23 are arranged on the outer wall of the No. 1 rotating rod 221, and a plurality of I-shaped components 23 are included in the I-shaped component 23, and a plurality of I-shaped parts 231 are distributed in an array and fixedly connected to the outer wall of the No. 1 rotating rod 221, and a No. 1 sliding bar 232 is slidably connected to the inner side of the I-shaped part 231, and the lower end of the No. 1 sliding bar 232 is attached to the fixed plate 211, and a slope 233 is provided on the top of the I-shaped part 231, wherein the slope 233 and the triangular hypotenuse of the triangular column 2 are in the same straight line.

[0044] like Figure 6As shown, a sampling chamber 3 is provided on the side of the triangular column 2 away from the regular conveyor belt 17, and the sampling chamber 3 is fixedly connected to the inner side of the guard plate, and the inner wall of the sampling chamber 3 is distributed and fixedly connected with partitions 31 in an array, and a slope 311 is provided on the top of the sampling chamber 3, and a crushing chamber 32 is fixedly connected between every two partitions 31, and a square hole for biscuit crumbs to fall is fixedly connected to the bottom of the crushing chamber 32, and a measuring cup 33 is provided below the crushing chamber 32, and a telescopic rod is provided at the bottom of the measuring cup 33, and the measuring cup 33 is placed on the placement table on the top of the telescopic rod.

[0045] It can be seen from this that when it is necessary to sample and test the biscuits during the production process, Figure 2-Figure 6 As shown, the staff first inverts the fermented dough onto the No. 1 conveyor belt 12, and conveys it toward the extrusion roller 15 on the No. 1 conveyor belt 12. After reaching the position of the extrusion roller 15, the dough is squeezed by the extrusion roller 15 and the No. 1 conveyor belt 12 to a dough cake of the same width and thickness and falls onto the No. 2 conveyor belt 13. Under the conveyance of the No. 2 conveyor belt 13, the dough cake is conveyed in the opposite direction of the No. 1 conveyor belt 12 until it falls onto the No. 3 conveyor belt 14, and under the conveyance of the No. 3 conveyor belt 14, the dough cake is conveyed to the bottom of the pressing roller 16, and under the pressure of the grid shell 161, the dough cake is cut into biscuits of the same size and shape and samples smaller than the biscuits, and then enters the oven for baking under the continued conveyance of the No. 3 conveyor belt 14. The oven here can be a tunnel oven for baking (not shown in the figure, the oven is located between the No. 3 conveyor belt 14 and the triangular column 2, and the conveying device in the oven is connected to the No. 3 conveyor belt 14);

[0046] It should be noted that the conveying direction of the No. 1 conveyor belt 12 is the same as that of the No. 3 conveyor belt 14, and the conveying directions of the No. 1 conveyor belt 12 and the No. 3 conveyor belt 14 are opposite to the conveying direction of the No. 2 conveyor belt 13. In addition, under the influence of the No. 1 gear 122 and the No. 3 gear 151, the rotation direction of the extrusion roller 15 is opposite to that of the No. 1 conveyor belt 12. During the conveying process of the No. 1 conveyor belt 12, the No. 2 conveyor belt 13 and the No. 3 conveyor belt 14, after falling to the position of the No. 3 conveyor belt 14, because the length of the dough cake may be too long, a dough cake dividing tool is set at the end position of the No. 3 conveyor belt 14, and each batch after cutting is conveyed to the pressing roller 16 for pressing sampling;

[0047] When the biscuits baked in the oven are then conveyed to the position of the triangular prism 2, the end of the oven distinguishes the baked biscuits from the biscuit samples by setting an imaging sensor. Because the biscuit samples are obviously smaller than the biscuit products, the servo motor 22 is started when the biscuit samples are conveyed to the end of the oven. At this time, the No. 1 rotating rod 221 and the multiple I-shaped pieces 231 are rotated 180 degrees together under the drive of the servo motor 22. During the rotation process, when the sample falls on the inclined surface 233 of the I-shaped piece 231, the No. 1 sliding bar 232 is restricted by the fixed plate 211, and the No. 1 sliding bar 232 is lifted up to block the biscuit sample. After the I-shaped piece 231 rotates 180 degrees, the slope 311 on the other side will be in the same straight line with the triangular hypotenuse of the triangular prism 2, which will not affect the conveyance of the biscuit products.

[0048] This allows for periodic small-scale sampling tests during the production of finished biscuits, which not only allows for the understanding of the test results of some batches, but also takes into account the differences in the data to be tested in the same batch. At the same time, multiple samples can be tested for multiple types of fungi at the same time, and production can be adjusted in a timely and effective manner, which can effectively improve the yield rate.

[0049] Embodiment 2

[0050] To achieve this the biscuit samples were ground and mixed with sterile saline solution, e.g. Figure 7-Figure 8As shown, the detection component 4 includes a double-axis motor 41, the double-axis motor 41 is fixedly connected to the inner side of the crushing chamber 32, the upper and lower output ends of the double-axis motor 41 are fixedly connected to the second rotating rod 42, the lower end of the second rotating rod 42 is fixedly connected to the stirring rod 421, the upper end of the second rotating rod 42 is fixedly connected to the connecting rod 422, the connecting rod 422 is fixedly connected to a raised column 4221 at the top away from the second rotating rod 42, the connecting rod 422 is fixedly connected to a fixed plate 4222 at the bottom of the end away from the second rotating rod 42, a cleaning plate 4223 is fixedly connected to one side of the fixed plate 4222, the bottom of the fixed plate 4222 is rotatably connected to the crushing wheel 43, the outer wall of the partition 31 is slidably connected to the second sliding bar 442, the second sliding bar 442 penetrates the partition 31, and the second sliding bar 442 passes through the partition 31. A rack 4421 is fixedly connected to one side of 42, an arch piece 44 is fixedly connected to the bottom of the No. 2 sliding bar 442, an arch piece 44 is provided with an arch hole 441 on the outer wall of the arch piece 44, and the width of the arch hole 441 matches the diameter of the raised column 4221, a sliding column 45 is slidably connected to the top of the No. 2 sliding bar 442, a sliding plate 46 is slidably connected to the top of the sliding column 45, a tooth groove 461 is provided on the inner outer wall of the sliding plate 46, and a push plate 46 is fixedly connected to the end of the sliding plate 46 close to the ramp 311, and a No. 4 gear 47 is meshedly connected to one side of the rack 4421, and the No. 4 gear 47 is fixedly connected to a rotating connecting rod 471 through a column, and the outer wall of the rotating connecting rod 471 at the end away from the column is gear-shaped, and the gear-shaped end of the rotating connecting rod 471 matches the tooth groove 461.

[0051] It can be seen that when the biscuit sample needs to be mixed with sterile saline, Figure 6-Figure 8As shown, when the biscuit sample is conveyed to the position of the slope 311, the end of the sliding plate 46 and one side of the push plate 462 in the initial state are in contact with the slope 311, and the arch 44 in the initial state is on the side close to the partition 31, that is, at the edge of the detection component 4. At this time, the second rotating rod 42 rotates under the drive of the dual-axis motor 41, and the second rotating rod 42 drives the connecting rod 422 to rotate, and the connecting rod 422 will slide together with the second sliding bar 442 and the arch 44 because of the raised column 4221. At this time, during the sliding process of the second sliding bar 442, the fourth gear 47 and the rotating connecting rod 471 will rotate together due to the drive of the rack 4421. At this time, the rotating The connecting rod 471 makes the gear-shaped end fit with the tooth groove 461, and makes the sliding plate 46 away from the slope 311, so that the biscuit sample slides into the grinding chamber 32. At this time, during the rotation of the connecting rod 422, the grinding wheel 43 at the bottom thereof is driven to rotate at the bottom of the inner wall of the grinding chamber 32 to grind the biscuit sample, and under the push of the cleaning plate 4223, the biscuit sample falls from the square hole in the grinding chamber 32 into the measuring cup 33 with sterile saline. Similarly, during the rotation of the second rotating rod 42, the stirring rod 421 is driven to fully mix the biscuit sample crumbs and the sterile saline to prepare a suspension. Finally, the measuring cup 33 is taken out by the staff and placed in the culture medium for subsequent testing.

[0052] It should be noted that during the rotation of the connecting rod 422, the protruding column 4221 will slide left and right along with the rotation of the protruding column 4221. Since the protruding column 4221 slides in the arch hole 441, the arch member 44 and the second sliding bar 442 will be driven to slide back and forth. Then the fourth gear 47 and the rotating connecting rod 471 driven by the rack 4421 will also reciprocate. This means that each biscuit sample will be blocked by the sliding plate 46 and the push plate 462. After a suspension is made, the detection component 4 stops working until the next batch of biscuit samples arrives.

[0053] Embodiment 3
