In order to preserve the nutrients in fresh milk better, kill as many harmful bacteria as possible in fresh milk.leader Engineers are committed to researching UV disinfection devices，combined with microwave sterilization equipment，designed LD1903Microwave ultraviolet liquid beverage sterilization equipment.It not only can protect the beneficial substances in liquid drinks, but also kills as much harmful substances as possible in liquid drinks.
The structure of the LD1903 Microwave ultraviolet liquid beverage sterilization equipment:
LD1903 Microwave ultraviolet liquid beverage sterilization equipment comprises a cylinder, a quartz tube coaxially sleeved in the cylinder, a resonant cavity coaxially arranged in the quartz tube and composed of a high-frequency block for generating a microwave discharge, and a cavity disposed in the resonant cavity A number of UV lamps.
LD1903 Microwave ultraviolet liquid beverage sterilization equipment’s two axial ends of the cylinder are correspondingly sealed to the two axial ends of the quartz tube.A liquid beverage inlet pipe and a liquid beverage discharge pipe are connected to the cylinder, and a first microwave end of the cylinder is connected with a microwave source for generating microwaves,The microwave outlet of the microwave source is in communication with the resonant cavity, and the second shaft end of the cylinder is connected with a cooling component for cooling the ultraviolet lamp,The outer coaxial sleeve of the quartz tube is provided with a bellows, and the two axial end edges of the bellows are respectively sealedly connected with the inner wall of the cylinder body,The gap between the bellows and the quartz tube constitutes a liquid beverage sterilization and disinfection channel, and the liquid beverage sterilization and disinfection channel is respectively connected with the liquid beverage inlet pipe and the liquid beverage discharge pipe.

The structural function of the LD1903Microwave ultraviolet liquid beverage sterilization equipment：
1.By providing a cavity for generating microwave discharge in the quartz tube，An ultraviolet lamp tube is disposed in the resonant cavity, and a bellows is coaxially disposed outside the quartz tube.In this way, the microwave generated by the microwave source enters the resonant cavity and flows in the resonant cavity during use，The resonant cavity acts to allow ultraviolet light to be emitted to prevent microwave leakage.
2.According to the actual application, a liquid beverage conduit can be connected to the liquid beverage discharge pipe，The liquid beverage draft tube is connected to the liquid beverage inlet tube of the other Microwave ultraviolet liquid beverage sterilization equipment，That is, two microwave ultraviolet liquid beverage sterilization and disinfection devices are connected by a liquid beverage guiding tube，In practice, a plurality of microwave ultraviolet liquid beverage sterilization and disinfection devices can be connected in series to sterilize and sterilize liquid beverages，In order to complete the sterilization process of liquid beverages in one time, shorten the sterilization time。
3.The microwave flowing in the cavity is absorbed by the gas inside the ultraviolet lamp, and the ultraviolet lamp is excited to generate ultraviolet rays，ultraviolet radiation enters the tube through a liquid beverage connected to the barrel into a liquid beverage in a liquid beverage sterilization channel formed by a gap between the bellows and the quartz tube，achieve the purpose of sterilization of liquid beverages，at the same time, because the bellows is transmitted to the flowing liquid drink。
Under the disturbance, the liquid drink is in agitated state，in this way, the uniform sterilization and disinfection of the flowing liquid beverage is realized quickly and easily, and the sterilization and disinfection effect is greatly improved，goodly preserved beneficial substances in liquid drinks and killed as many harmful bacteria as possible in liquid drinks；on the other hand, since the ultraviolet lamp is placed in a cavity that is transparent to ultraviolet rays, the ultraviolet rays emitted from the ultraviolet lamp can be 100% utilized.
4.LD1903Microwave ultraviolet liquid beverage sterilization equipment by setting a bellows, the anti-virus disinfection effect is greatly improved，it is not only simple in structure, but also effective in disinfecting and disinfecting liquid beverages such as milk and granules with high concentration and low transparency.
5.It is best to have four UV tubes 4 when conditions permit，And the four ultraviolet lamps 4 are distributed 360 degrees, so that the ultraviolet rays emitted by the four ultraviolet lamps 4 can completely disinfect the liquid beverage in the liquid beverage sterilization and disinfection channel 7.

Two methods of traditional milk sterilization：
Pasteurization is divided into high temperature short time pasteurization (HTST) method and low temperature long time pasteurization (LTST) method,The high temperature short-time pasteurization method is to warm the raw milk to 72-85 degrees Celsius, and then cool it after 15-20 seconds.This is a fresh milk sterilization method commonly used by dairy companies, it can not only preserve the nutrients in fresh milk, but also kill most harmful bacteria in raw milk；
Low temperature long-time pasteurization method is to keep the raw milk at 63 degrees Celsius for 30 minutes to achieve pasteurization，since the fresh milk after sterilization has a short shelf life and still has some heat-resistant bacteria, this method is less used in liquid milk production.
2.Ultra high temperature instantaneous sterilization (UHT) method.
The ultra-high temperature instantaneous sterilization method is to rapidly heat the raw milk through a heat exchanger to a temperature of 135 to 140 degrees Celsius in a continuous flow state for 3 to 4 seconds to achieve a commercial aseptic sterilization method，It completely eliminates all the microorganisms in the raw milk, leaving only the protein，at the same time, because the temperature is too high, the taste and protein of milk are also damaged. Therefore, the taste and nutritional value of UHT milk are far worse than pasteurized milk.
