Problems solved by technology

[0004] The object of the present invention is to provide a detection device and method for detecting the airtightness of canned food, which solves the problem that the position of the problem food cannot be accurately determined when the existing canned food is tested for airtightness and needs to be checked for the entire batch. The detection of canned food results in low calibration efficiency and affects normal production

Embodiment 1

[0037] Such as Figure 1 to Figure 3 As shown, the present invention provides a detection device for detecting the airtightness of canned food, including a plurality of food transportation lines 1 arranged in parallel and a filling method for filling food on the plurality of food transportation lines 1 Device 2, multiple food transportation lines 1 are equipped with a classification detection device 3 for detecting the air tightness of canned food, and the classification detection device 3 determines the canned food through the classification detection of the filling device 2 and canned food Whether the food airtightness is qualified;

[0038] The grading detection device 3 includes a plurality of sensing elements 301 arranged on the filling device 2 for measuring filling pressures on different food transportation lines 1 and a plurality of induction elements 301 arranged on different food transportation lines 1 for isolating unqualified canned foods. A food isolation structu...

Embodiment 2

[0090] The present invention also provides a detection method of a detection device for detecting the airtightness of canned food, comprising the steps of,

[0091] S100, the food is transported on the food transportation line and filled by the filling device, and at the same time, the filling pressure of the filling device is detected by the sensing element, and compared with the preset pressure value to determine whether the filling pressure is qualified;

[0092] S200, when the sensing element detects that the filling pressure is normal, the food isolation structure and the airtight detection structure do not act; when the sensing element detects that the filling pressure exceeds the preset pressure value range, the food isolation structure acts to intercept through the transfer baffle Canned food that passes through the filling device during the inspection period and is transferred to the airtight inspection structure through the transfer structure for separate inspection; ...

Abstract

The invention discloses a detection device and method for detecting the air tightness of canned food, comprising a plurality of food transportation lines arranged in parallel and a filling device arranged on the plurality of food transportation lines for filling food , the present invention detects the filling pressure of the filling device in real time through the sensing element. If the filling pressure meets the requirements, the airtightness of the canned food on the food transportation line is good. When the filling pressure is detected to be unqualified, the food isolation The structure transfers the canned food that passed the inspection period to the airtight inspection structure for inspection, avoiding the mixing of unqualified products and qualified products, and screening out batches with unqualified products in time, reducing the number of inspections, passing The two graded inspections improve the detection efficiency and reduce the impact on production. Secondly, multiple food production lines are produced and transported in parallel, which greatly improves the production efficiency, further reduces the number of batches of unqualified products, and improves the detection efficiency.

Description

technical field [0001] The invention relates to the technical field of food packaging, in particular to a detection device and method for detecting the air tightness of canned food. Background technique [0002] Canned food is a method of storing food. High-temperature-treated food is put into tin cans and vacuum-treated. High-temperature treatment and vacuum packaging make the food preservation period longer. [0003] In the production process of canned food, it is necessary to ensure that the airtightness of the filling process is good, so as to avoid the damage of its vacuum state and affect the long-term storage of food. It is necessary to test the airtightness of canned food to ensure the filling Qualified, to prevent the food in the can from being contaminated and deteriorated by microorganisms. Currently, when testing the air tightness of canned food, the air pressure of the inflation device of the filling equipment is generally detected. When the air pressure inside ...
