Description

Technical Field

[0001] The utility model belongs to the field of yak milk sampling devices, in particular to a portable thermal ultrasonic device used for enzyme-inactivating freshness preservation of raw yak milk. Background Art

[0002] Yaks are widely distributed in high-altitude mountainous plateaus in Qinghai, Tibet, Sichuan, Gansu, Yunnan and other provinces in my country. Their geographical location is relatively remote and transportation is inconvenient. At the same time, herders still continue the breeding method of "traditional family ranches, natural grazing and free-range", and the process of collecting yak milk is relatively complicated. In addition, due to the large particle size and membrane surface area of ​​yak milk fat globules, there are more dispersed lipid rafts on the milk fat globule membrane, resulting in poor mechanical resistance and easy cleavage during milking, packaging and transportation. More specifically, unlike ordinary cow milk, the endogenous lipoprotein lipase of yak milk is mainly distributed in the whey and fat phases. If the yak milk is directly refrigerated after being squeezed, it will induce the endogenous lipoprotein lipase in the whey to enrich in the milk fat globule membrane, further accelerate fat hydrolysis, and produce lactic acid rancidity (mutton smell), thereby reducing the sensory quality and processing performance of raw yak milk, which is not conducive to the development of subsequent experiments and the determination of related indicators.

[0003] The existing ultrasonic devices and constant temperature system devices in the laboratory are relatively large, with poor functional integration and low efficiency, and are not easy to carry when taking samples outside. Although there are mini ultrasonic crushers, there are no suitable constant temperature devices and auxiliary operation equipment.

[0004] Therefore, there is an urgent need to develop a portable, intelligent and suitable thermal ultrasonic device for outdoor sampling to solve the problem of passivation of endogenous lipoprotein lipase activity in milk samples before refrigerated transportation, thereby improving the quality of raw yak milk used in experiments.
