Milk fat determination system

Abstract

The invention discloses a milk fat determination system. The system comprises a stirring device, a cooling-water machine and a milk fat determinator which are sequentially arranged, wherein the milk fat determinator comprises a first machine body and a second machine body arranged at the lower end of the first machine body, the first machine body and the second machine body are integrally formed, a water outlet, a liquid discharge port and a water inlet are formed in the side wall of the second machine body, the liquid discharge port and the water inlet are located in the same horizontal plane, and the water outlet is located right below the liquid discharge port; a frame lifting rod and a display screen are sequentially arranged on the front side of the second machine body in the horizontal direction, a frame lifting handle is arranged at the upper end of the frame lifting rod, and the lower end of the frame lifting rod penetrates through the second machine body and extends into the second machine body. Operation of the system is controlled by a smart system and is more standard, accuracy and repeatability are good, water bath, stirring, cooling, layering, centrifugation, extraction, solvent recovery and sample drying are integrated, operation steps are simplified, and operation is simpler.

Description

technical field [0001] The invention relates to the technical field of milk fat measurement, in particular to a milk fat measurement system. Background technique [0002] The determination of milk fat is carried out in accordance with the third method of GB 5009.6-2016 "National Food Safety Standard for the Determination of Fat in Food": alkaline hydrolysis method. Extract the alkaline hydrolyzate of the sample with diethyl ether and petroleum ether, remove the solvent by distillation or evaporation, and measure the quality of the extract dissolved in the solvent. Specifically: first dissolve the dairy products, add alkaline substances, such as ammonia water, to disperse the colloids in the solution; then, add ethanol, the function of adding ethanol is to precipitate proteins to prevent emulsification, and dissolve alcoholic substances, so that It stays in the water; finally add the mixture of diethyl ether and petroleum ether, fully mix the above solution, let it stand for...

AI Technical Summary

Problems solved by technology

[0003] At present, the determination method is manually operated, and the ether layer needs to be poured many times during the operation, and the steps are cumbersome.

The water and ether layer separation liquid level is not easy to control, the influence of human factors is large, the repeatability and accuracy are poor, and the test failure rate is high
