Example Embodiment

[0026] Example 1

[0027] The present invention provides a kind of impurity detection equipment in milk, such as figure 1 As shown, the detection device includes at least one conductivity detection unit 10 , at least one temperature detection unit 20 , at least one data processing unit 30 and at least one display unit 40 . Wherein, the conductivity detection unit 10 and the temperature detection unit 20 may adopt the same detection equipment as described in the prior art document described in the background art section, or other commonly used electronic sensors capable of detecting conductivity and temperature, specifically, the conductivity The detection unit 10 and the temperature detection unit 20 may be configured to simultaneously measure a conductivity value K and a temperature value T of the milk (raw milk or fresh milk) to be detected.

[0028] The detection device for impurities in milk according to the present invention is a detection device that can be applied to a...

Example Embodiment

[0052] Example 2

[0053] The present embodiment provides a method for detecting impurities in milk using the above-mentioned detection equipment for impurities in milk, the method comprising the following steps:

[0054] The standard electrical conductivity value K of the milk to be detected at different temperatures T is stored in the data processing unit 30 S ;

[0055] A preset deviation reference value K is stored in the data processing unit 30 P ;

[0056] A conductivity value K and a temperature value T of the milk are simultaneously detected by the conductivity detection unit 10 and the temperature detection unit 20;

[0057] Compare the measured conductivity value K under the temperature value T with the standard conductivity value K S Compare to obtain a deviation value K R , when the deviation value K R greater than the above-mentioned deviation from the reference value K P , the data processing unit 30 sends a first signal to the display unit 40; when the de...

Example Embodiment

[0067] Example 3

[0068] This embodiment presents a verification example of detecting impurities in milk using the detection equipment for impurities in milk in Example 1 of the present invention.

[0069] First, select the milk module by operating the selection module 36 displayed on the display unit 40 on its display screen.

[0070] Then operate the selection on the display screen to set the deviation reference value K of the corresponding milk P is 0.05ms / cm.

[0071] Take a lot of 50mL of the milk to be tested in a beaker, measure the sample with the milk impurity detection device of the present invention, put the conductivity detection unit 10 and the temperature detection unit 20 into the sample to be tested at the same time, and shake gently to make the milk and the conductivity. After the electrodes and temperature probes of the rate detection unit 10 and the temperature detection unit 20 are in full contact, read the readings and record the results.

Abstract

The invention provides a detection device for detecting the impurity in milk and a detection method thereof; the detection device comprises at least a conductivity detection unit, at least a temperature detection unit, at least a data processing unit and at least a display unit; the data processing unit can compare a measured conductivity value under a temperature value with the stored standard conductivity value to obtain a deviation value; when the deviation value is greater than the pre-stored deviation reference value, the data processing unit sends a first signal to the display unit; and when the deviation value is less than the deviation reference value, the data processing unit sends a second signal to the display unit. The device can simultaneously carry out automated inspection and monitoring on a plurality of production lines and various impurities, so as to effectively reduce the inspection time and manpower input; therefore, the device can be used for rapid online qualitative detection.

Description

technical field [0001] The invention relates to a detection device for impurities in milk and a detection method thereof, in particular to a detection device and a detection method for impurities in milk which are convenient for judging whether there is adulteration or impurities in milk. Background technique [0002] Due to various reasons, some impurities may be mixed in the raw milk or fresh milk used for processing into finished products, such as the milk produced by sick cows. Various adulterated substances or even toxic substances may be added to the milk in the milk. Excessive intake of adulterated substances by the human body will cause various harms. However, the current national standard method on whether milk is adulterated with impurities is very limited and cannot meet actual needs. [0003] The on-line quality control of milk purchase needs to adopt a detection method that is fast, convenient, low in detection cost and capable of comprehensive detection. Alth...
