Description

Technical Field

[0001] The utility model relates to the field of food detection, in particular to a pulverizing device for food detection. Background Art

[0002] Food inspection in a broad sense refers to a discipline that studies and evaluates food quality and its changes. It is based on some basic theories and various technologies of physics, chemistry, and biochemistry, and in accordance with established technical standards, such as international and national food hygiene / safety standards, to inspect the quality of food raw materials, auxiliary materials, semi-finished products, finished products, and by-products to ensure that the product quality is qualified. The content of food inspection includes sensory testing of food, testing of nutrients, additives, and harmful substances in food, etc., and quality testing of food raw materials, auxiliary materials, semi-finished products, and finished products to determine whether the nutrients, additives, and harmful substances therein are within the specified numerical range. The specific detection steps include sampling, crushing, preparation and physical and chemical testing. Crushing is to crush the collected samples to facilitate the full dissolution of various substances in the samples in the reagents. Some existing crushing and crushing equipment crush the samples by high-speed rotating cutters, which is similar to a wall breaking machine. However, when such equipment is working, the cutters directly cut the samples, and the cutter blades wear out very quickly, so the cutters need to be replaced frequently. In addition, the cutters make a lot of noise when working in the initial stage. For this reason, application number: CN202321581835.1 discloses a food detection crushing equipment, including an intermediate, an extrusion cover, a crushing cover and a pressure rod. The top surface of the intermediate is provided with an upper threaded ring, and the bottom surface is provided with a lower threaded ring. The extrusion cover can be threadedly connected to the upper threaded ring or the lower threaded ring, and the crushing cover can be threadedly connected to the upper threaded ring or the lower threaded ring; the pressure rod is threadedly installed in the extrusion cover, and a pressure block is provided at the front end of the pressure rod and a handle is provided at the rear end. When the pressure rod rotates, the pressure block enters the central area of ​​the upper threaded ring; a rotatable shaft is provided in the crushing cover, and a plurality of blades are provided on the side of the shaft. The utility model first squeezes the food sample, and then when the blade is broken, the working noise is small, the wear degree of the blade can be reduced, and the service life of the blade is extended; through the two methods of squeezing and cutting, the sample can be fully crushed, and the crushing effect is better.

[0003] However, the above scheme still has certain defects. The inventors have found through research that in the above scheme, when crushing the food sample, it is first necessary to extrude the sample through the extrusion component, and then replace the crushing component to crush the sample. Firstly, replacing different processing components is relatively troublesome, which reduces the efficiency of crushing the sample. Secondly, flattening the food sample is not convenient for the subsequent crushing process, which further reduces the crushing efficiency.

[0004] How to invent a food testing crushing device to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 6 The utility model provides a technical solution: a crushing device for food inspection, including a containing tube 1, the bottom end of the containing tube 1 is connected to a base 2, the top of the containing tube 1 is connected to an end cover 3, a blade mesh plate 4 is fixedly connected between the inner walls of the containing tube 1, a pressing mechanism is arranged on the end cover 3, and a crushing mechanism is arranged in the base 2.

[0024] See also Figure 2 and Figure 5 An installation cavity 201 is provided inside the base 2, and a connecting cavity 202 is provided above the installation cavity 201. The installation cavity 201 and the connecting cavity 202 are both independent chambers. An opening is provided at the top of the connecting cavity 202, and a threaded groove is provided on the inner wall around the connecting cavity 202. A connecting port 101 is provided at the bottom end of the accommodating tube 1. The outer wall diameter of the connecting port 101 is consistent with the inner wall diameter of the connecting cavity 202 and a thread is provided on the outer wall. The accommodating tube 1 is threadedly connected to the installation cavity 201 through the connecting port 101.

[0025] When the accommodating tube 1 and the base 2 are threadedly connected together, the connection port 101 is located inside the communicating cavity 202 to enhance the sealing performance. The threaded connection method is relatively stable and easy to disassemble and assemble.

[0026] Furthermore, the crushing mechanism includes a motor 203, which is fixedly mounted on the inner wall of one side of the mounting cavity 201. One end of the output shaft of the motor 203 extends into the connecting cavity 202 through a through hole and is fixedly connected to one end of the rotating shaft 204. A plurality of groups of blades 205 are arranged on the outer wall of the rotating shaft 204 and are evenly distributed in a ring shape along the extension direction thereof.

[0027] The rotating shaft 204 is located in the connecting cavity 202. When the accommodating tube 1 is connected to the base 2, the food sample inside the accommodating tube 1 will enter the bottom end of the accommodating tube 1 and the connecting cavity 202. The motor 203 is started to drive the rotating shaft 204 to rotate. The food sample is further crushed by several groups of blades 205 arranged on the outer wall of the rotating shaft 204, so that the food sample can be easily tested.

[0028] Furthermore, a plurality of groups of heat dissipation holes 206 evenly distributed in an annular shape are arranged on the outer wall of the installation cavity 201 .

[0029] The heat dissipation holes 206 can allow air in the installation cavity 201 to circulate, thereby taking away the heat generated by the motor 203 when it is working, so as to prevent the food sample from being affected by the heat generated by the motor 203 when it is working, thereby reducing the accuracy of detection.

[0030] Furthermore, a protective ring 207 is provided on the outer wall of the top opening of the installation cavity 201 , and the inner wall diameter of the protective ring 207 is consistent with the outer wall diameter of the accommodating tube 1 .

[0031] Part of the rotating shaft 204 will extend out of the connecting cavity 202, so that after the containing cylinder 1 is connected to the base 2, part of the rotating shaft 204 can enter the interior of the containing cylinder 1 to crush the food sample to improve efficiency. By providing a protective ring 207 on the outer wall of the connecting cavity 202, a protective effect can be played to prevent the staff from accidentally touching the extended part of the rotating shaft 204 when separating the containing cylinder 1 and the base 2 to take out the crushed sample, thereby preventing accidental injury, thereby improving safety during use.

[0032] See also Figure 2 and Figure 6 A protrusion is provided on the bottom surface of the end cover 3, and a thread is provided on the outer wall of the protrusion. A threaded groove is provided on the inner wall of the top circumference of the accommodating tube 1. The end cover 3 is threadedly connected with the top of the accommodating tube 1 through the protrusion. The pressing mechanism includes a pressing plate 301, and the pressing plate 301 is located inside the accommodating tube 1. One end of a threaded rod 302 is fixedly connected to the top surface of the pressing plate 301. A threaded hole is provided through the top surface of the end cover 3, and the threaded rod 302 is threadedly connected to the threaded hole. A knob 303 is provided at the other end of the threaded rod 302.

[0033] The threaded rod 302 is rotated by the knob 303 to make the threaded rod 302 independently displaced relative to the end cover 3 in the threaded hole, thereby driving the pressing plate 301 to descend inside the accommodating tube 1, pushing the food sample onto the blade mesh plate 4, and performing preliminary cutting of the sample by the blade mesh plate 4, so that the size of the sample is easier to be crushed, thereby improving the efficiency of the crushing work.

[0034] See also Figures 1 to 3 A plurality of anti-slip rubber strips 5 evenly distributed in an annular shape are arranged on the outer walls of the accommodating tube 1 and the end cover 3 .

[0035] The anti-skid rubber strip 5 can be provided to facilitate the user to disassemble and assemble the accommodating tube 1, the base 2 and the end cover 3, thereby avoiding the situation that the disassembly and assembly are difficult due to slipping, thereby improving the convenience in use.

[0036] Working principle: first, remove the end cover 3 as a whole, prevent the food sample from being located above the blade mesh plate 4 inside the accommodating tube 1, and then install the end cover 3 at the top of the accommodating tube 1. By rotating the threaded rod 302, the pressing plate 301 is driven down to push the food sample to the surface of the blade mesh plate 4. The blade in the blade mesh plate 4 and the pressure applied by the pressing plate 301 are used to perform preliminary cutting of the food sample, so that the cut size is more convenient for crushing. After the cut food sample passes through the blade mesh plate 4, it enters the lower end of the accommodating tube 1 and the connecting cavity 202. The motor 203 is started to drive the rotating shaft 204 to rotate. The sample is further crushed by a plurality of groups of blades 205 arranged on the outer wall of the rotating shaft 204. After the crushing is completed, the device is turned over as a whole, so that one end of the base 2 is upward and the base 2 is removed, and then the residue of the food sample is dumped out. By arranging the blade mesh plate 4 inside the accommodating tube 1, the cutting and crushing steps can be directly performed at one time to avoid the need to replace the end head and then crush after cutting. Therefore, by arranging the blade mesh plate 4, both the crushing efficiency and the convenience of use are improved.

[0037] It should be noted that the specific model and specifications of the motor 203 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

[0038] The power supply and principle of the motor 203 are clear to those skilled in the art and will not be described in detail here.

[0039] The above description is only the preferred implementation 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.
