[0002] The statements herein merely provide background art related to the present invention and do not necessarily constitute prior art.

[0003] Food testing samples usually include sampling, crushing, weighing, extraction, separation, and testing. Since food safety rapid testing has the characteristics of large sample volume, many sample types, and fast circulation speed, and its testing process has very high efficiency requirements, but the pre-treatment of samples often takes up most of the testing process, which will seriously affect the testing efficiency. At present, laboratories and on-site rapid testing mostly use traditional knife cutting or shearing, then crushing with a food processor, and finally weighing with a spoon scale. The process is relatively cumbersome and takes a long time to labor.

[0004] In the prior art, Chinese utility model patent CN214668049U discloses a handheld rapid food pulverizing sampler for food testing, which achieves food pulverization by setting two mutually meshing pulverizing wheels. The device has the following problems: the pulverization is only performed by the pulverizing wheel, which leads to the problem of incomplete pulverization, and the uneven pulverized particles will affect the detection results; in addition, the pulverized food is discharged and collected through the discharge port, and it is still necessary to weigh and quantitatively sample by a balance or a measuring cup. The process is relatively cumbersome and takes a long time of manpower, resulting in reduced detection efficiency. Utility Model Content

[0026] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0027] Example 1

[0028] In a typical implementation of the present invention, Figure 1 As shown, a pulverizing and sampling device for food detection is provided, including a shell 1, in which a first pulverizing chamber 101, a second pulverizing chamber 102 and a collecting chamber 103 are arranged in sequence from top to bottom, a first hole sieve plate 6 is arranged between the first pulverizing chamber 101 and the second pulverizing chamber 102, and a second hole sieve plate 7 is arranged between the second pulverizing chamber 102 and the collecting chamber 103; a first pulverizing device 2 is arranged in the first pulverizing chamber 101, and a second pulverizing device 3 is arranged in the second pulverizing chamber 102, a material outlet is arranged at the bottom of the collecting chamber 103, and a quantitative sampler 4 is arranged at the material outlet.

[0029] In this embodiment, the first pulverizing device 2 includes a first rotating shaft 202, a spiral blade 203 and a motor 201. The spiral blade 203 is installed on the first rotating shaft 202. One end of the first rotating shaft 202 is connected to the output shaft of the motor 201. Furthermore, the motor 201 is arranged on the top of the shell 1. One end of the first rotating shaft 202 passes through the wall of the shell 1 and is connected to the output shaft of the motor. The motor drives the first rotating shaft to rotate, and then drives the spiral blade to rotate. The spiral blade is used to achieve initial shredding of food to improve pulverizing efficiency.

[0030] In this embodiment, the second crushing device 2 includes two crushing rollers 301 that rotate in mesh with each other, one of which is an active crushing roller and the other is a driven crushing roller, wherein the active crushing roller is connected to the output shaft of the motor through the second rotating shaft 301, and the motor drives the active crushing roller to rotate, thereby driving the driven crushing roller to rotate, and the food is crushed by the bite force generated when the two crushing rollers are meshed, thereby improving the crushing efficiency of the crushing device.

[0031] In this embodiment, if Figure 2 As shown, the outer periphery of the quantitative sampler 4 is provided with a plurality of crushed material holding spaces 401, and the volumes of the plurality of crushed material holding spaces 401 are the same. A third rotating shaft 402 is provided at the center of the quantitative sampling, and the third rotating shaft 402 is connected to a rotating handle. The sample obtained by the quantitative sampler 4 is poured into the sampling box by rotating the handle. Since the volume of the crushed material holding space on the quantitative sampler is fixed, when sampling, the number of times the crushed material holding space needs to be poured can be calculated according to the amount to be sampled, so as to realize quantitative sampling. Furthermore, the third rotating shaft on the quantitative sampling sampler can be connected to a motor, and quantitative sampling can be realized by controlling the speed and angle of the motor.

[0032] In this embodiment, the first hole sieve plate 6 and the second hole sieve plate 7 are detachably mounted on the housing 1. The first hole sieve plate 6 and the second hole sieve plate 7 can be removed in time for cleaning and convenient replacement. The aperture of the first hole sieve plate 6 is larger than the aperture of the second hole sieve plate 7. The first hole sieve plate 6 is used to coarsely screen the food that has been crushed once, and the second hole sieve plate 7 is used to finely screen the food that has been crushed twice, so as to achieve uniformity of particle size of the finally collected samples and ensure the quality of food testing. The specific aperture size can be set according to different foods and different experimental needs.

[0033] Furthermore, the second hole sieve plate 7 is connected to the vibration motor 11. Since the aperture of the second hole sieve plate 7 is small, in order to prevent the accumulation of crushed materials on the second hole sieve plate 7, the vibration motor 11 drives the second hole sieve plate 7 to vibrate, so that the crushed materials fall into the collection chamber below in time.

[0034] In this embodiment, a handle 8 and a feed port 104 are provided on the top of the shell 1, and a support leg 9 is provided at the bottom of the shell. An anti-slip pad 10 is provided on the support leg 9. The handle 8 is provided to facilitate carrying the food crushing sampler, and the food to be crushed is added to the first crushing chamber through the feed port 104. The support leg 9 provides support for the entire device, and the anti-slip pad can reduce shock and prevent slipping of the device body during crushing, thereby improving the working stability of the crushing sampler.

[0035] In this embodiment, the bottom of the first pulverizing chamber 101 and the bottom of the collecting chamber 103 are both inclined surfaces. The inclined surfaces are provided to guide the flow of the pulverized material, thereby preventing the pulverized material from accumulating in the shell.

[0036] When in use, the food to be tested is fed in from the feed port at the top of the housing, the food is shredded in the first pulverizing chamber under the action of the first pulverizing device, the shredded food is filtered through the first hole screen plate and enters the second pulverizing chamber, the food is pulverized under the action of the second pulverizing device 3, and the pulverized food enters the collection chamber under the action of the second hole screen plate. After the pulverization is completed, when sampling is required, the sampling box is placed at the discharge port of the collection chamber, and the quantitative sampler is rotated according to the required sampling amount to achieve quantitative sampling.

[0037] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
