Filtering device for food detection

Abstract

The invention discloses a filtering device for food detection. The filtering device comprises a shell, an extrusion device and a fixing device, the extrusion device comprises a motor B, a left half gear, a right half gear, a movable plate, a rack plate, a guide column and a supporting plate, the left half gear or the right half gear is connected with the output end of the motor B, the left half gear is in transmission connection with the right half gear, and a rack meshed with the right half gear is arranged on the right side of the movable plate; a rack meshed with the left half gear is arranged on the left side of the rack plate; guide grooves are formed in the middle of the rack plate and the middle of the movable plate, and the guide columns penetrate through the guide grooves; the guide column is in sliding connection with the rack plate and the movable plate; a fixing rod and a pressing plate are arranged at the bottom of the rack plate; the bottom of the movable plate is connected with a push plate; a filter bag is fixed at the upper end of the push plate, and a filter hole is formed in the bottom of the filter bag; and the fixing device is used for fixing the material cup. The problem that pores are blocked due to high solution concentration is solved, and the problem of low filtering efficiency is also solved.

Description

technical field [0001] The present application relates to the field of food testing equipment, in particular to a filter device for food testing. Background technique [0002] Food testing is a method to test whether food is safe according to national standards, such as the determination of acid value and peroxide value in food. [0003] Filtering equipment is often required for food testing. When the existing filtering device is filtering, when the concentration of the solution is high, the particles in the solution tend to deposit and cause the pores to be blocked. Moreover, the cleaning of the filter device is inconvenient, which may easily lead to cross-infection between the food used next time. At the same time, the existing filter device generally uses the gravity of the food to filter the debris or solution in the food, which will consume a lot of time and filter. The efficiency is low, therefore, it is urgent to design a filter device for food detection with anti-c...

Problems solved by technology

When the existing filter device is filtering, when the concentration of the solution is high, the particles in the solution are prone to deposit and cause the pores to be blocked

And the cleaning of the filter device is inconvenient, which may easily lead to cross-infection between the next-time used food. At the same time, the existing filter device generally uses the gravity of the food to filter the debris or solution in the food, which will consume a lot of time and filter. The efficiency is low, therefore, it is urgent to design a filter device for food detection with anti-clogging function to solve the above problems

[0004] The patent application number is CN202020293805.0 (patent name: a filter device for food detection with anti-clogging function). The patent discloses a filter device for food detection, which solves the problems of inconvenient cleaning and low filtration efficiency of the filter device , but when it is used, the solution is in direct contact with the filter device, so it needs to be cleaned every time it is used. If it is not cleaned, it will also cause cross-infection between test samples
