Description

Technical Field

[0001] This utility model relates to the field of food testing technology, specifically to an ultra-low temperature pulverizing device for food testing. Background Technology

[0002] The raw materials for food mainly come from agricultural and sideline products. From planting, breeding, harvesting, processing, packaging, transportation, and sales, to reaching people's tables, agricultural and sideline products go through many processes. Food safety problems can occur at any stage of production and processing. Currently, food safety problems occur frequently in my country, and how to ensure food safety has become a matter of great concern to people. Food testing can detect harmful substances in food, mainly some harmful and toxic indicators, such as heavy metals and aflatoxins. It is currently an important technical means to verify food safety.

[0003] Before food samples are tested, they need to be pre-treated. A common procedure is to crush and stir the food to allow for the testing of various indicators.

[0004] However, when testing pesticide content in fruits and vegetables, it is necessary to test whether the residue exceeds the standard. Generally, the fruits and vegetables are crushed and mixed with a solvent, and the pesticide content is tested by chemical methods. The quality of crushing the fruits and vegetables affects the degree of mixing with the solvent, which in turn affects the detection of pesticide content. However, fruits and vegetables are generally plastic and not brittle enough, making them difficult to crush completely and time-consuming.

[0005] Furthermore, the active substances inside the sample are destroyed at high temperatures during the pulverization process, affecting the accuracy of subsequent test data. Utility Model Content

[0006] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide an ultra-low temperature pulverizing device for food testing, which effectively solves the problem that existing ultra-low temperature food testing devices are not easy to pulverize products.

The cryogenic generator 3 is disposed on the side wall of the main body 1 and communicates with the interior of the main body 1 for cryogenic control within the main body 1. Under the rotation of the pulverizing blade 2, the food to be tested can be pulverized.

[0025] It also includes a pre-crushing treatment structure on the main body 1. The pre-crushing treatment structure is used for auxiliary cutting before food crushing. Through pre-crushing auxiliary cutting, large pieces of food can be first divided into suitable small pieces, which allows the crushing blade 2 to crush the food better.

[0026] The pre-processing structure includes a cover, an auxiliary cutting component, and a drive component. The cover works with the main body 1 to block the opening of the main body 1. The auxiliary cutting component is located on the cover and is used for auxiliary cutting before food is crushed. The drive component is detachably connected to the crushing blade 2 and is used to drive the crushing blade 2 to rotate. The drive component is connected to the auxiliary cutting component for the auxiliary cutting component to move back and forth. The drive component can not only drive the crushing blade 2 to rotate, but also drive the auxiliary cutting component to move up and down, so as to achieve the pre-cutting of food.

[0033] When using this utility model, the staff opens the space between the upper cover 6 and the lower cover 7 and places the food in the space formed between the upper cover 6 and the lower cover 7. The blade mesh 4 supports the food. The staff then fastens the upper cover 6 and the lower cover 7 together. At the same time, the limiting block 16 is inserted into the limiting groove 15 to limit the upper cover 6.

[0034] When the food is located between the upper cover 6 and the lower cover 7, the motor 9 is started. The motor 9 drives the rotating shaft 10 to rotate. Under the action of the reciprocating thread on the rotating shaft 10, the auxiliary plate 8 drives the pressure block 5 to move downward and pass the food through the blade mesh 4. Under the action of the blade mesh 4, the food is initially cut.

[0035] At the same time, when the upper cover 6 and the lower cover 7 are fastened together, the tenon 12 on the rotating shaft 10 is inserted into the tenon groove 11. When the motor 9 is started, the motor 9 can drive the crushing blade 2 to rotate through the rotating shaft 10, thereby further crushing the initially cut food.
