The necessity of temperature controller for temperature monitoring in cold chain

With the continuous development of national economy, people's material life level has been rapidly improve, people on food freshness, nutrition and food safety requirements also gradually improve, temperature controller has been more widely used. We get a set of statistics from online query: at present our country 80% of the fresh food or use the form of normal temperature logistics, postpartum circulation losses accounted for 12% of total output of grain 15%, fruit and vegetable loss rate of 25% - 32%, egg corrosion rate was 5%, and the consumption of CHC metamorphism was 3%, and therefore caused a direct economic loss of about 75 billion yuan a year. In recent years, the production and sales of food and feed in the form of popular created the conditions for the spread of foodborne diseases, the incidence of foodborne illness gradually increased, solve the problem of food safety is more urgent and important. And low temperature cold storage can keep food flavor, color and nutrition better and higher safety of edible, full use temperature controller to keep constant temperature condition. Domestic in recent years, put forward the concept of cold chain logistics is generally refers to the temperature sensitivity of the product in the production, storage, transportation, sales, to the consumption of each link, always in the provisions of the low temperature environment, temperature controller, temperature control, to ensure the quality of goods, reduce the loss of the logistics a systems engineering. It is with the logistics technology, refrigeration technology development and set up, based on refrigeration technology, by means of refrigeration technology low temperature logistics process. Cold chain by frozen processing, frozen storage, cold storage, transport and distribution, refrigeration sales four aspects. The need for food cold chain transport generally have cold drinks, dairy products, meat products, medicines, vaccines, etc. Most of the dairy products need to use the temperature controller, all in Chinese can guarantee quality, low temperature cold chain distribution and sales in the whole process of the dairy at the time of the preservation of 0 to 10 ℃ temperature regulation; Mall or supermarket cold storage, cold air temperature should be controlled at about 2-6 ℃. And most of the medical blood, biological agents and drug because of protein instability, the easily affected by environmental temperature change biological medicines, drugs and blood, vaccines, metamorphic, so need more accurate temperature control.
