Description

Technical Field

[0001] This utility model belongs to the technical field of food sample pretreatment equipment, specifically relating to a solid food pulverizing device with a screen. Background Technology

[0002] In the field of food testing, for samples such as rice and tea, according to relevant standards, sample preparation usually requires pulverization and sieving. Taking common testing items as examples, in the detection of aflatoxin B1 (GB 5009.22), it is stipulated that the sampling amount of solid samples (such as grains and their products, nuts and seeds, infant cereal complementary foods, etc.) must be greater than 1 kg, pulverized, and then sieved to make the particle size less than 2 mm; for the detection of methylmercury (GB 5009.17), for dry samples of rice, edible fungi, aquatic animals and their products, it is required that the edible part be pulverized evenly with a particle size of less than 425 μm (equivalent to more than 40 mesh); for the detection of fipronil (GD23200.34), it is required that 500g of sample be sieved through a 20-mesh sieve and mixed evenly.

[0003] Currently, sample pretreatment involves first crushing the sample with a pulverizer, and then sieving the crushed sample through a sieve with a corresponding aperture. This traditional method has significant drawbacks: not only is the pretreatment inefficient, but it also requires an additional sieve with a different aperture, making the entire process time-consuming, labor-intensive, and cumbersome.

[0004] A search revealed Chinese patent document CN214952483U, which discloses a small pulverizer for food testing. The pulverizer includes a base, a working housing connected to the top of the base, a vibration motor mounted on the inner bottom wall of the working housing, a transmission rod connected to the output end of the vibration motor, a support plate connected to the top of the transmission rod, a baffle plate on the surface of the support plate, a locking block connected to the inner wall of the working housing, a connecting cover above the locking block, and a rotating motor installed on the inner wall of the connecting cover. This invention, by incorporating a vibration motor, drives the transmission rod to vibrate, which in turn causes the support plate to shake. This shakes the pulverized food on the support plate, preventing it from sticking to the screen and causing screen blockage, thus ensuring the pulverized food can fall off and continue processing. The device is simple to operate, easy for users to use, and improves its practicality, meeting user needs.

[0005] The shredder screen of the aforementioned patent is set on the support plate below the processing frame. During sieving, a vibration motor needs to be started to vibrate so that the shredded sample falls into the collection box. This sieving method has the problem that the sieving structure is relatively complex and inconvenient to use. Utility Model Content

[0006] This invention provides a solid food pulverizing device with a screen, which solves the above-mentioned technical problems.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: A solid food pulverizing device with a screen includes: a pulverizing main unit with a pulverizing chamber inside and pulverizing blades driven by a drive device at the bottom; a cover on the main unit to close the pulverizing chamber; and a sieving assembly including: a screen on the mounting area of ​​the cover; the area of ​​the screen is smaller than the area of ​​the cover; and the orthographic projection of the screen is inside the pulverizing chamber.

[0027] To facilitate a better understanding of this utility model, the following examples are provided in conjunction with the accompanying drawings. These examples fall within the protection scope of this utility model, but do not limit the protection scope of this utility model.

[0028] Example 1 A solid food pulverizing device with a screen, such as Figures 1-3 , Figure 5 As shown, it includes: a pulverizing host 1, which has a pulverizing chamber 11 inside and a pulverizing blade 12 driven by a drive device at the bottom; a cover 2, which is provided on the host 1 to close the pulverizing chamber 11; and a screening assembly 3, which includes: a screen 31, which is provided on the mounting area 21 of the cover 2; the area of ​​the screen 31 is smaller than the area of ​​the cover 2; the orthographic projection of the screen 31 is inside the pulverizing chamber 11.

[0029] The pulverizer is an existing product. A drive unit, such as a motor, is located inside the base to drive the pulverizing blades to rotate, thus pulverizing the sample added to the pulverizing chamber. The motor used is an existing product, and its specific model will not be described. The installation and fixing of the motor in the base, the cable connection, the installation and fixing of the output end to the pulverizing blades, and the operation methods are all existing technologies and will not be described in detail. A controller is located on the bottom side of the pulverizer. The controller has a control area with buttons for start / stop, speed setting, and pulverizing time, facilitating the control of the motor's start / stop and pulverizing parameters such as speed and time. The controller and drive unit are connected using existing methods; the controller itself is an existing product, and its model will not be described here.

[0030] The bottom of the pulverizer can be equipped with a suction cup, which can be used to fix it to the operating table to prevent shaking during pulverization.

[0031] The installation area is equipped with a screen, and the screen aperture can be selected according to the sample crushing requirements; therefore, multiple machine covers can be prefabricated, and the screen aperture specifications used on the machine covers are different, so as to meet the sieving needs of different samples.

[0032] The shredder blades are existing products, and their specific specifications and dimensions are sufficient to meet the requirements of the shredding samples, so they will not be described in detail here.

[0033] The cover and the main crusher are separate units. The main crusher and the cover can be locked together using existing locking methods, such as food-grade silicone seals on the edge of the cover. When in use, the cover is pressed down, and the silicone seals on the side deform under the pressure and move downward against the inside of the main crusher, so that the cover is tightly closed on the main crusher, preventing the cover from loosening during the crushing process and causing the crushed sample particles to escape.

[0034] Instructions for use: Open the machine cover, place an appropriate amount of the sample to be crushed (solid sample) into the crushing chamber, and then tighten the machine cover; set the crushing speed, time and other parameters, start the crushing host, and the crushing blades will crush the sample; after crushing, invert the crushing host so that the crushed sample falls through the sieve on the machine cover into the sample collection container; after the sample is sieved, open the machine cover and clean the machine cover, crushing chamber and crushing blades.

[0035] Example 2 This utility model also has the following technical features: like Figures 1-2 As shown, the screening assembly 3 also includes: a retaining ring 32, with a matching retaining groove on the side of the corresponding installation area 21; a screen 31 disposed on the retaining ring 32; the screen 31 and the retaining ring 32 are disposed on the side near the crushing chamber 11.

[0036] like Figure 4 As shown, the area of ​​the installation area 21 is 0.6-0.8 times the area of ​​the cover 2.

[0037] The screen is installed on the retaining ring, which is installed in the installation area. The two are locked together by the retaining groove. Since the cover has a certain thickness, the screen is set on the side of the cover near the crushing chamber, and the screen is as flush as possible with the cover on that side to avoid forming a groove that would cause the sample to stick to that area during the crushing process.

[0038] To facilitate material screening and discharge, the installation area on the machine cover can be set to a larger area, such as 0.6-0.8 times the size of the machine cover; after crushing, it is easier to screen out the sample particles.

[0039] Example 3 This utility model also has the following technical features: like Figure 1 , Figures 5-6 As shown, the cover 2 is also provided with a feeding area 22; the feeding area 22 is located on one side of the installation area 21; the area of ​​the feeding area 22 and the installation area 21 is smaller than the area of ​​the cover 2.

[0040] like Figure 1 , Figures 5-6 As shown, the installation area 21 and the feeding area 22 are symmetrically arranged with the center line of the machine cover 2 as the axis.

[0041] like Figure 1 , Figures 5-6 As shown, the machine cover 2 is provided with a first cover plate 23, the area of ​​which is slightly larger than the area of ​​the installation area 21; the machine cover 2 is provided with a second cover plate 24, the area of ​​which is slightly larger than the area of ​​the feeding area 22; the first cover plate 23 and the second cover plate 24 can be fastened with a buckle on the side near the edge of the machine cover 2.

[0042] If the sample needs to be added for crushing in stages during the crushing process, a feeding area can be set on the machine cover. After the added sample is crushed, the crushing host is stopped, and the sample to be crushed is added from the feeding area. Then the sample can be crushed again, thereby improving the convenience of operation.

[0043] To prevent sample particles from escaping through the screen or feeding area due to the high-speed rotation of the blades during the crushing process, thus causing sample waste, a first cover plate and a second cover plate are respectively installed to seal the installation area and feeding area when the crushing host is running. The area of ​​the first cover plate and the second cover plate can be slightly larger than the installation area and feeding area to facilitate clamping and fixing with the machine cover. The first cover plate is located above the screen.

[0044] The first cover plate and the second cover plate are connected to the machine cover separately. They are locked using existing locking methods, such as food-grade silicone seals on the sides of the first cover plate and the second cover plate. When in use, the first cover plate and the second cover plate are pressed downwards, and the silicone sealant deforms and moves downwards along the side walls of the installation area and the feeding area, so that the first cover plate and the second cover plate tightly seal the installation area and the feeding area respectively, preventing the first cover plate and the second cover plate from loosening during the crushing process and causing the crushed sample particles to escape.

[0045] Example 4 This utility model also has the following technical features: like Figure 6 As shown, the cover 2 is provided with a handle 25; the handle 25 is located between the installation area 21 and the feeding area 22; the orthographic projection of the handle 25 is not within the range of the installation area 21 and the feeding area 22.

[0046] like Figure 6 As shown, the handle 25 is made of existing elastic material, which makes it easy to lift the cover when needed. The specific material is not described in detail.

[0047] To facilitate opening the machine cover, a handle is provided on the cover. The handle is located in the cover area between the installation area and the feeding area. It is made of elastic material and can be lifted when needed. When not in use, the handle will be attached to the cover to avoid affecting the sieving of the sample after crushing.
