  • The Vertical ultrasonic washing machine adopts automatic drainage technology for the first time, which realizes easy one-click drainage, thus having reduced the labor intensity and improved customer experience


  • Control of Water and air spraying time and circulation water temperature

Water and air spraying time of the vial washers can be controlled via formula directly, while circulating water temperature can be controlled by the upper and lower setting limits and the upper and lower alarm limits. When the temperature is below the lower setting limit, the Heater in the bottom water tank will start heating, while when the temperature is above the upper setting limit, the heater will stop heating; there is a certain value difference between the upper and lower setting limits and the upper and lower alarm limits, and the circulating water temperature shall be Controlled between the upper and lower alarm limits.

  • Washer high speed feeding technology for large size vials

The vial washers adopt brand-new single-row vial-feeding + parallel track spraying method, which has increased the vial washers’ large size via speed from 60pcs/min to 100pcs/min, and improved operation efficiency of the equipment by 67%.

  • Feedback technology for water-air joint control

This technology has resolved the washer spraying needle without block detection function problem. It will get accurate feedback of pressure from the pipeline with the pressure transmitter to know the flow condition inside the pipeline. Also, it can avoid the machine running without the control valve not open which will ultimately affect the cleaning efficiency. It achieves all the internal/external spraying's pressure detection.

  • The ultrasonic washing machine adopts low-friction protection technology, which guarantees the vials without scratch at the out-feed station


  • The Sterilizing & drying tunnel assembles pipelines of the Conveyor belt and the surface cooler at the lower section of preheating zone to facilitate connection of the customer’s pipelines


  • Forced air compensation technology in high-temperature zone

KSZ1200 model forms forced air compensation by adding fan-filter system in the air compensation location, which is more convenient to regulate the pressure difference in high-temperature section; forced air compensation can increase exchange efficiency of internal humid and hot air, and enable a higher temperature rise efficiency of bottles; at the end of production, the inside of the tunnel cools faster than natural air compensation.

  • Intelligent emptying and Smart tail-liquid filling technology

Filling technology has always been an important core part in filling production line of sterile injections, and high value-added injection drugs must meet high standards during the filling production process, as well as the stability and reliability requirement for filling precision. It is very important as for how to realize automatic calibration of filling amount in the production preparation stage with minimum or even zero liquid loss; how to guarantee non-drifting of the filling amount and realize process quality control of 100% filling amount during the filling production process; how to empty tail liquid with the minimum residue or even reduce the material loss to the amount of a vial in Empty Mode at the end of the filling production stage, however, for traditional filling technology, there will generally be tens and even a hundred of vials with non-conforming filling amount per batch, as well as filling vials with high value-added or multiple batches, causing the pharmaceutical enterprises to have a product value loss up to several millions yuan every year.


TRUKING TECHNOLOGY’s European Institute of R&D and Central Institute of R&D have gathered multi-disciplinary engineers such as mechanical engineers, automatic control engineers, CFD engineers, and AI engineers, etc., and they have achieved technological breakthrough upon accumulation and repeated verification of the joint researches in recent two years, and successfully developed near-zero-residue Smart Filling automatic emptying filling system and software technology, which can perfectly control minimization of liquid residue, and enable maximization of economic benefit of pharmaceutical enterprises.
