　　Mixer optimized design

　　The mixer is an important component of the beverage packaging line equipment is the key technology and equipment that directly determines the quality of the finished beverage composition. For rapid consumption and fashion features a wide variety of beverage production, mixed than accurate, convenient adjustment, high efficiency and low consumption, reliable operation of the technology to locate, is the goal of the mixer equipment product development.

　　If the mixer as a closed system, temporarily ignore secondary factors related to the system, first focus on the input-output relationship of the research system, through the analysis of the basic input output modulus. He Xiaowu, it is essential to water treatment. Drink mixer water is a major component of the finished beverage, in accordance with the proportion of mixed drink ingredients through the precise measurement, added to the concentrated slurry mixing process. Required after membrane

　　filtration, ozone or ultraviolet sterilization to ensure that the water quality colorless, odorless and sterile water supply to the mixer. Its degassing in the mixer on. Degassing of the water here in order to complete the follow-up carbonated. Theoretically, through a different process combinations, you can get many different design of the mixer. But in fact, the principles of design of the carbonated beverage mixer There are basically two categories, first, a flow control, one volume control type. Measurement state, the dynamic measurement of mixer and static bulk metering mixer. Ho deputy director said, we only made three mixer principle design of a comparative evaluation of

　　Programme I: Flow control type mixer. Clean water and a thick paste using the centrifugal pump to send (and there are clean water centrifugal pump to send to send a thick paste using a piston pump). The current introduction of heavy industry technology DBC-type mixer and beer

　　dilution machine of this type, its complex structure, the proportional control valve is a key component.

　　Program II: volume control mixer. Sent by the centrifugal pump clean water after vacuum degassing the middle tank. Its clean water metering and the concentrated slurry metering, respectively, each with a plunger metering pumps, plunger metering pump here in the transportation of materials at the same time, according to the mixed than required materials

　　quantitatively, the frequency of its measurement process by regulating piston pump stroke and the role of , to achieve the purpose of precise adjustment of flow. The current introduction and similar mixer technology to produce YL3B mixer. Domestic production of this type of mixer, its plunger metering pumps need to import supporting expensive. Is a dynamic measurement, the long-term high-intensity production run, it is

　　inevitable wear and tear, so its cost and operating costs are higher Programme III: Static volume measurement mixer. Such mixer is

　　characterized by the use of container, liquid level sensors, and enter the thick paste and water purification level of the continuous detection of the level signal is sent to a computer equipped with a mathematical model, by default procedure the whole process of the mixing process for continuous control of the whole system is basically no moving parts, do not wear mixed than the accuracy level of mixed materials rely on the liquid level sensor accurate measurement, batch complete quantitative mixed, although the mixing process is cyclical work, but the output of the entire system (such as transport to the filling machine) is continuous and uniform.

　　Mixer requirements mixed-precision, high-speed and convenience,

　　efficiency and low consumption, reliable operation, positioning, static volume measured mixer is clearly superior to other types of design principles. Nanjing Light Factory in the digestion and absorption of foreign advanced technology, will launch a new mixer with independent
