A kind of lactic acid bacteria beverage shelf life quality detection sensor and detection method

Abstract

The invention discloses a lactobacillus beverage shelf life quality detection sensor and a lactobacillus beverage shelf life quality detection method. The sensor comprises a gas chamber and an infrared light signal module. The gas chamber is connected with a base and provided with a gas inlet and a gas outlet, a gas flow cavity is arranged inside the gas chamber, and a rotatable mirror is arranged on one side of the gas chamber and can rotate under drive of external force. The infrared light signal module is arranged on the outer side of the rotatable mirror; when the rotatable mirror is in a first state, two 45-degree reflecting mirrors on the rotatable mirror do not block incident light of the infrared light signal module, light rays are emitted into the gas flow cavity, and emergent light returned from the gas flow cavity is received by a light receiver in the infrared light signal module; a microprocessor is used for storing and processing received signals and displaying processed results. The lactobacillus beverage shelf life quality detection sensor and the lactobacillus beverage shelf life quality detection method have the advantages that different from that whether lactobacillus beverages deteriorate or not is judged according to color, luster, bubbles, volume expansion, smell and taste of lactobacillus beverages, a novel detection means is provided, and the relation between deteriorated gas overflow concentration and lactobacillus beverage deterioration is quantified; directness is achieved, and data are provided accurately.

Description

technical field

[0001] The invention relates to sensor technology, in particular to a gas sensor made by using an optical method to measure the different absorption values ​​of specific frequency light by different gases, especially the technology for detecting the gas spilled from spoiled lactic acid bacteria beverages. Background technique

[0002] In the prior art, lactic acid bacteria beverages are generally not stored for too long after leaving the factory, and should usually be sold within 15 days, and expired beverages are not suitable for drinking.

[0003] After the lactic acid bacteria beverage produced by the applicant adopts a special formula and a special process, the shelf life can be extended by 2 months, and the quality remains unchanged. Although the product can have a longer shelf life, in actual operation, it is necessary to take a certain amount Since there is no professional quality testing instrument, it is generally judged according to the color, air b...

Examples

Embodiment Construction

[0038] Combine below Figure 1 to Figure 4 The preferred embodiments shown further describe the invention in detail.

[0039] Such as figure 1 Shown, design and manufacture a kind of lactic acid bacteria beverage shelf-life quality detection sensor, described sensor comprises:

[0040] An air chamber 4, the interior of the air chamber 4 is an airflow cavity 41, and the air chamber 4 is connected to the base 5;

[0041] The air chamber 4 has an air inlet 44 and an air outlet 45;

[0042] A moving mirror 3 is arranged on the other side of the air chamber 4, and the moving mirror 3 can be driven by an external force to rotate at an angle greater than 10° and less than 90°. The side of the moving mirror 3 facing the airflow cavity 41 is a plane mirror, and the other side is set at 45° The first inclined mirror 35 and the second inclined mirror 36;

[0043] An infrared light signal module 2 is arranged on the outside of the moving mirror 3. When the moving mirror 3 is in the fi...
