AI Technical Summary

Technical Problem

Insufficient contact between the food being tested and the strong acid solution in the acid-resistant container affects the accuracy of the test results.

Method used

A decomposition device for food hygiene and safety testing was designed, comprising a primary crushing component and a secondary crushing and decomposition component. By utilizing the cooperation of a turntable, blades, and paddles, a turbulent flow and negative pressure zone is formed to enhance the fluidity of the strong acid solution. The food particles are brought into full contact with the acid solution through the gaps between the blades. Furthermore, the food particles are further crushed by the cooperation of the primary crushing component and the filter cartridge, increasing the contact area.

Benefits of technology

This improves the accuracy and safety of food testing results, ensures the full release of the elements to be tested, reduces particle size, increases the contact area with acid solutions, and enhances the accuracy of test results.

Abstract

The invention relates to a decomposition device for food sanitation and safety detection. The decomposition device comprises a container, a feeding pipe, a preliminary crushing assembly, a driving part, a rotating disc, a circular ring, a plurality of blades, a first elastic piece and a shifting piece. Turbulent flow is formed in the container through rotation of the blades, a negative pressure area is formed on the upper portion of a strong acid solution, the strong acid solution carries food particles to be discharged from gaps between the blades and then flows upwards to enter an annular space formed by the blades from a circular ring, circular flow is formed, and part of the food particles collide with the surfaces of the blades to be smashed. The rotating blades reversely rotate to compress the first elastic pieces under the blocking action of the stirring pieces, when the blades are separated from the stirring pieces, the first elastic pieces release elastic potential energy to drive the blades to reset, part of food particles can be actively extruded by the blades to be further crushed, the contact area between the food particles and a strong acid solution is increased, crushing and decomposition are conducted at the same time, and the crushing efficiency is improved. Sufficient release of the to-be-detected element is facilitated, and the accuracy of a detection result is improved.
