Technical Field

The invention relates to the technical field of food detection, in particular to a filtering device for food inspection.

Background

The food safety detection is used for detecting harmful substances in food according to national indexes, mainly for detecting some harmful and toxic indexes such as heavy metal, aflatoxin and the like, and an important aspect of food science and engineering is to introduce and apply chemical engineering unit operation and develop and form food engineering unit operation, so that the development of the food industry to large-scale, continuous and automatic directions is promoted.

The filtration refers to a process of purifying and purifying fluid by a special device, the filtration mode is various, the used systems are wide, and solid-liquid, solid-gas, large particles and small particles are common. The filtration is an operation that under the action of a driving force or other external force, liquid (or gas) in suspension (or heating gas containing solid particles) permeates through a medium, and solid particles and other substances are intercepted by the filter medium, so that the solid and other substances are separated from the liquid (or gas).

Food detection's in-process need stir the bits of broken glass earlier and dissolve food, then filter, detect the sample after filtering, current filter equipment is at filterable process, and the deposit can take place for the particulate matter that contains in the solution, will cross the filtration pore and plug up, influences filterable effect, and the filterable precision of current filter equipment is not high simultaneously, can only obtain one kind and filter the sample to the filtration process all relies on gravity to drench and drips, and filterable efficiency is lower.

Chinese patent (publication number: CN 210543575U) discloses a filtering device for food detection, which comprises a base, wherein the top of the base is fixedly connected with a shell, the top of the shell is provided with an inlet, the right side of the shell is fixedly provided with a motor, an output shaft of the motor is fixedly connected with a short rod, the top end of the short rod is movably sleeved with a connecting rod, the left end of the connecting rod is movably sleeved with a stirring rod, the outer surface of the stirring rod is fixedly connected with a stirring plate, the inside of the shell is fixedly provided with a first filter screen positioned at the bottom of the stirring plate, the bottom of the first filter screen is fixedly provided with a first collecting bin, although the filtering device can realize the filtering of food in the food detection to a certain extent and obtain samples with different granularity, the filtering device can be realized only by arranging a plurality of vertical three-dimensional filter screens, thereby not only increasing the device cost, and also are not easy to handle, so further improvements are still needed.
