Description

Technical Field

[0001] The present invention relates to the technical field of food detection, and more specifically to a pretreatment device for solid food detection. Background Art

[0002] In food science and industry, cereal foods are an important part of human diet, and the accuracy of their composition testing is crucial to ensure food safety, nutritional value and consumer health. However, for cereal foods processed into solid form, the process of composition testing is not without challenges.

[0003] When analyzing the specific components of solid food, the food may need to be processed before testing by slicing or grinding it into powder. Among them, although slicing sampling can obtain internal information of food to a certain extent, during the storage and processing of grain foods, due to the influence of environmental factors such as humidity and temperature, the content of materials at the bottom is often higher. This physical distribution unevenness is particularly obvious when slicing, because the slices can often only represent the composition of a certain level of food, and cannot fully reflect the true situation of the whole piece of food.

[0004] Although solid food ground into powder can help reduce detection errors caused by uneven distribution of components inside the sample, making it easier to operate in subsequent testing processes, during the pretreatment process of grinding the food, the heat accumulation caused by the continuous contact between the solid food and the food during grinding can easily lead to thermal decomposition or denaturation of some food components (such as protein, fat, sugar, etc.) at high temperatures. These changes will change the chemical structure, nutritional value and functional properties of the food, seriously affecting the detection accuracy. At the same time, there is another problem with the current grinding equipment. Other types of food powders from the last grinding may remain in the grinding equipment. After mixing with the food ground this time, it will inevitably lead to deviations and inaccuracies in the test results.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a pretreatment device for solid food detection. Summary of the invention

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0030] Embodiment 1:

[0031] See also Figure 1-6, a pretreatment device for solid food detection, comprising a material grinder 1, a grinding wall 101 is arranged on the inner side wall of the material grinder 1, a feed port 2 for feeding food materials to be detected is arranged on the outer side wall of the material grinder 1, it is worth noting that the mass of the food materials to be detected each time is quantitative, a motor 3 is installed on the upper top of the material grinder 1, a rotating shaft 4 is fixedly connected to the power output end of the motor 3, a crushing leaf 5 is fixedly connected to the outer end of the rotating shaft 4, and the falling point of the food material in the feed port 2 corresponds to the crushing leaf 5, the crushing leaf 5 is used to preliminarily crush the food material into small pieces, a grinding cylinder 6 is also fixedly connected to the end of the rotating shaft 4 away from the motor 3, a grinding ring 7 is provided between the grinding wall 101 and the outer wall of the grinding cylinder 6, the interior of the grinding cylinder 6 is hollow, and the upper part of the grinding cylinder 6 is in the shape of a spire, and the small pieces of food materials preliminarily crushed by the crushing leaf 5 slide from the spire into the grinding ring 7, An auxiliary material dropping and cooling mechanism is arranged between the material grinder 1 and the grinding cylinder 6. The diameter of the grinding ring 7 gradually decreases from top to bottom. The shape design of the grinding ring 7 in this scheme can effectively prevent the backflow and diffusion of food material powder, and the auxiliary material dropping and cooling mechanisms are distributed on both sides of the grinding ring 7. In the process of grinding food materials, the grinding ring 7 is an area that is prone to heat accumulation during the grinding process. A material holding box 12 is arranged at the inner end of the material grinder 1 and at the lower side of the grinding ring 7. The ground powdered food automatically flows to the material holding box 12. A movable door 1201 is arranged on the front surface of the material holding box 12 for hinge connection therewith. A sealing layer is fixedly connected to one end of the movable door 1201 close to the material holding box 12. A movable material receiving mechanism is slidably connected in the material holding box 12. An electrical control mechanism is arranged between the movable material receiving mechanism and the material holding box 12. A pair of fans 18 are arranged at the inner top of the material grinder 1.

[0032] See also Figure 1-5The auxiliary blanking and cooling mechanism includes a plurality of assembly chambers 102 arranged on the inner wall of the material grinder 1 and an assembly chamber 2 601 arranged on the inner wall of the grinding cylinder 6. The assembly chamber 102 and the chute 2 602 are respectively provided with a chute 103 and a chute 2 602. The assembly chamber 102 and the assembly chamber 2 601 are both provided with an impact ball 8. The impact ball 8 includes a wrapping layer 801, a magnetic ball 802 and a slider 803. The wrapping layer 801 is coated on the outer end of the magnetic ball 802. The wrapping layer 801 is a rubber layer. The outer end of the wrapping layer 801 is fixedly connected with the slider 803. The slider 803 is slidably connected to the chute 103 and the chute 2 602. The magnetic ball in the assembly chamber 102 and the assembly chamber 2 601 is connected to the magnetic ball 802. The magnetic poles of the ends of the assembling chamber 102 that are close to each other are the same, and a micro-compression spring 9 is fixedly connected between the inner bottom end of the assembly chamber 102 and the impact ball 8 located therein. The magnetic repulsion between the pair of magnetic balls 802 is greater than the elastic force of the micro-compression spring 9 acting on the impact ball 8 in the assembly chamber 102. When the pair of magnetic balls 802 rotate to a state corresponding to the position, the impact ball 8 in the assembly chamber 102 will squeeze the micro-compression spring 9. The assembly chamber 102 and the assembly chamber 2 601 are both filled with coolant 10. The coolant 10 is ethylene glycol-based coolant. This coolant is relatively friendly to the wrapping layer 801 and the micro-compression spring 9, is not easy to corrode the two, and has a high specific heat capacity and good thermal conductivity. The outer wall of the grinding cylinder 6 absorbs and disperses the heat at the grinding ring 7, and the coolant 10 does not directly contact the food material, so as to prevent the thermal decomposition or denaturation of some ingredients in the food at high temperature. During the operation of the equipment, the coolant 10 near the grinding ring 7 will be higher in temperature than the coolant 10 at other positions. The diameter of the wrapping layer 801 is smaller than the inner diameter of the assembly cavity 1 102 and the assembly cavity 2 601. During the sliding process of the impact ball 8 to the left and right, the coolant 10 at various locations can be mixed, and the coolant 10 at other locations with a relatively lower temperature can be transferred to the position near the grinding ring 7, and the volume of the coolant 10 accounts for 60%-63% of the volume of the assembly cavity 1 102 or the assembly cavity 2 601. This will make the impact ball 8 partially exposed to the air, the fluid resistance it encounters is small, and it is easier to slide left and right. The outer ball of the rubber wrapping layer 801 can provide a certain elasticity. When the motor 3 drives the rotating shaft 4 and the grinding cylinder 6 to rotate, the impact ball 8 is affected by the centrifugal force to impact the inner wall of the grinding cylinder 6, and preliminarily assists in material dropping. When the grinding cylinder 6 continues to rotate to make the position of the assembly cavity 2 601 correspond to the position of the assembly cavity 1 102, the impact balls 8 in the assembly cavity 2 601 and the assembly cavity 1 102 have the same magnetic poles at the ends close to each other. This magnetic repulsion can make a pair of impact balls 8 move toward the ends away from each other. Subsequently, as the grinding cylinder 6 continues to rotate, the assembly cavity 2 601 and the assembly cavity 1 102 are misaligned.Since a plurality of magnetic shielding strips 11 are fixedly connected to the inner wall of the material grinder 1 and located between two adjacent assembly cavities 102, and the shape of the magnetic shielding strips 11 is consistent with the shape of the inner wall of the grinder 1, the magnetic shielding strips 11 provide magnetic shielding between two adjacent magnetic balls 802. At this time, the impact ball 8 in the assembly cavity 2 601 is affected by the centrifugal force and moves toward the side close to the grinding ring 7 again, while the impact ball 8 in the assembly cavity 1 102 is reset due to the elastic force of the micro compression spring 9 and moves toward the side close to the grinding ring 7 again. Both back and forth processes can enable a pair of impact balls 8 to respectively separate the assembly cavity 2 601 and the assembly cavity 1 102. 2 is fully stirred, and the presence of the coolant 10 can also make the slider 803 slide left and right along the second slide groove 602 or the first slide groove 103 more smoothly. The coolant 10 that exchanges positions can ensure that the temperature at the grinding ring 7 will not accumulate heat due to grinding. This process can also make the two impact balls 8 impact the inner wall of the grinding cylinder 6 and the material grinder 1 respectively, and generate slight vibrations, further assisting the falling of the material, which can greatly reduce the accumulation and clogging effect between food particles or the adhesion effect between food powders, and help to disperse the food particles or grind the food powder evenly, thereby improving the grinding efficiency;,

[0033] See also Figure 1 and Figure 6The movable material receiving mechanism includes a detachable hopper 13, and a material trough 1301 is provided on the detachable hopper 13, which is located directly below the grinding ring 7. The material trough 1301 is a hemispherical material trough, and the inner surface of the material trough 1301 is coated with a smooth coating. This shape and material help to avoid the phenomenon that food powder remains inside the material trough 1301 when the food powder is poured out from the material trough 1301 for inspection. The diameter of the opening of the material trough 1301 is larger than the diameter of the bottom end of the grinding ring 7, and the end of the grinding ring 7 close to the material trough 1301 has a straight slide. The diameter gradually decreases. During the automatic dropping process, it is ensured that the food powder can easily fall into the trough 1301. A pair of symmetrically arranged guide grooves 1202 are provided on the material box 12. The left and right ends of the detachable hopper 13 are fixedly connected with guide members 1302 that are slidably connected to the guide grooves 1202. The guide members 1302 include guide rods and balls arranged at the outer ends of the guide rods. A spherical groove is provided at one end of the pair of guide rods away from each other. Balls are arranged in the spherical grooves. The guide grooves 1202 are "L"-shaped grooves. The ball bearings are arranged in the spherical grooves. The guide groove 1202 is connected by sliding, which can reduce the friction of the guide member 1302 when it slides in the guide groove 1202, and can effectively reduce the resistance of the detachable hopper 13 when it slides up and down or forward and backward. The ends of the detachable hopper 13 and the material box 12 that are close to each other are respectively fixedly connected with a magnetic piece 14 and a magnetic piece 2 15 with matching shapes and sizes. The ends of the magnetic piece 14 and the magnetic piece 2 15 that are close to each other have the same magnetic poles. The detachable hopper 13 is made of lightweight material, and the distance between the magnetic piece 14 and the magnetic piece 2 15 is 20mm. The magnetic repulsion force is greater than the gravity of the detachable hopper 13. When the trough 1301 is filled with powder that is 70% of the weight of the food material, the detachable hopper 13 squeezes the magnetic sheet 14 and gradually moves toward the end close to the magnetic sheet 2 15. The front surface of the detachable hopper 13 is fixedly connected with a pull handle 1303, and the outer end of the pull handle 1303 is fixedly connected with a rubber layer with anti-slip grooves, so that after the pretreatment of the food material is completed, the detachable hopper 13 can be taken out through the pull handle 1303, and the food powder in the trough 1301 can be poured out for inspection;

[0034] The electrical control mechanism includes a PLC controller, an electric contact 16 arranged on the lower surface of the detachable hopper 13, and an electric contact 2 17 arranged on the inner surface of the material box 12. The positions of the electric contact 16 and the electric contact 2 17 correspond to each other, and the input end of the PLC controller is connected to a pair of electric contacts, and the output end of the PLC controller is connected to the control circuit of the fan 18. A control program is compiled in the PLC controller. The program is: when the input signals of the electric contact 16 and the electric contact 2 17 are detected by the PLC controller, the PLC controller controls the fan 18 to start and simultaneously starts an internal timer. The internal timer is set to 15 seconds. After 15 seconds, the fan stops running and continues to execute the next logic. Within 3 minutes, the start of the fan 18 is no longer dependent on the electric contact 16 and the electric contact 2 17. During these 3 minutes, the personnel can take the processed food material powder out of the material grinder 1 for inspection; When 90% of the weight of the food material is accumulated in the trough 1301, the detachable hopper 13 slides downward, so that the electrical contact 1 16 and the electrical contact 2 17 will be in contact. At this time, the PLC controller receives the signal and controls the fan 18 to start. When 90% of the weight of the food material is accumulated in the trough 1301, it can be considered that all the food material has been ground into powder. Only part of the food powder on the upper side is retained on the upper side of the grinding ring 7 due to slow sliding, or a very small amount of powder that has not been shaken off adheres to the grinding ring 7. The fan 18 provides wind force and continuous magnetically controlled vibration to easily blow the food powder on the grinding ring 7 into the handle 1303, and finally obtains powder of the same quality as the food material, which can effectively prevent the food material ground at that time from mixing with the subsequently input samples, thereby improving the purity of the subsequently input samples and ensuring the analysis accuracy of the subsequent samples.

[0035] In this solution, an auxiliary material dropping and cooling mechanism is arranged in the material grinder 1, and the impact ball in the mechanism provides uninterrupted impact and vibration functions during the material grinding process, so as to promote the fluidity of the food material in the grinding ring 7, reduce the accumulation and clogging of the food material during the grinding process, and thus improve the grinding efficiency. At the same time, the vibration can drive the coolant 10 in the assembly chambers 1 and 2 to be fully stirred and mixed, and the coolant 10 with a relatively lower temperature is transferred to the side close to the grinding ring 7, so as to ensure that the coolant 10 can quickly absorb and disperse the heat generated during the grinding process, so as to prevent the thermal decomposition or denaturation of some components in the food at high temperature. The movable material receiving mechanism can be used in conjunction with the electrical control mechanism. After the material in the material trough 1301 reaches a certain amount, the fan 18 can be automatically driven to start to provide downward wind force to cooperate with the magnetically controlled vibration to blow the food material powder retained in the grinding ring 7 into the material trough 1301, which can effectively prevent the food material processed by the current grinding from mixing with the subsequent sample, thereby improving the purity of the subsequent sample and ensuring the analysis accuracy of the subsequent sample.
