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.

Freeze-dryer auto loading & unloading system come into use in early 1980s, and it is a full-automatic connection equipment that uses automation technology to complete half-stoppered vials from the filler to the freeze dryer, and then from the freeze dryer to the capping machine under the premise of meeting regulations. Upon several decades of development, it has formed several types as follows: Moveable auto loading & unloading system, Fixed row by row auto loading & unloading system, Mixed type auto loading & unloading system. Where, Fixed row by row auto loading & unloading system has been generally adopted by pharmaceutical enterprises and is most widely used since it has the advantages such as high automation, good repeatability, easy to verify, guarantee of stable and reliable product quality, and minimization of product contamination, etc.

With increasingly strict regulations, the pharmaceutical enterprises put forward a higher requirement for production cost, production efficiency and sterile guarantee of products, and the Auto loading & unloading system at present is also subject to challenges as follows:

1.Since the plant space is limited, how to lay out the automatic feeding and discharging?

2.How to avoid the loading pusher contamination risk when cross Grade A/ Grade B? /How to make sterile verification of the loading pusher bellows? /How to guarantee product sterility if laminar flow pattern in the location of loading pusher does not meet standard?

3.Since the order demand is big, how to improve the production capacity?

TRUKING TECHNOLOGY has always been adhering to the concept of being the “sole or first”, keeping forging ahead, and dedicated to providing the customers with efficient, stable and perfect solutions. Over many years of investment and innovation, it has successively launched integrated solution for biological lyophilization automatic feeding & discharging, integrated solution for RGV lyophilization automatic feeding & discharging, solution for APIs sterile lyophilization automatic feeding & discharging, solution for APIs tray lyophilization automatic feeding & discharging, and solution for non-sterile food lyophilization automatic feeding & discharging.

It can effectively reduce investment cost of the equipment, and maximize use value of the whole line.

Control of the biggest risk point in lyophilization production –TRUKING’s advanced shelf processing technology

Application of lyophilization technology started in early 1980s. Lyophilization refers to the method that freezes Liquid into solid by pre-cooling, and then sublimates water directly from solid into water vapor to obtain drying under the vacuum condition. Shelf is the core part of freeze dryer. It is the shelf used for storing products in the freeze-drying chamber during lyophilization process, and cooperates with the loading & unloading system to realize the products’ loading & unloading of the freeze-drying chamber, and in the meantime, the surface of the shelf is in direct contact with the product or product container, and it is also used for even heating and cooling of products.

In November 2019, TRUKING’s digital intelligent automatic welding line established a process digital traceability system that covers whole production cycle of shelfs. With digital tracking number as the core, it can meet shelf’s auxiliary feeding, automatic feeding & discharging, laser labelling, logistics transshipment, welding, automatic unit-polishing, automatic material-cleaning, leveling, sanding, flatness and roughness test, automatic integration and quality traceability function in the transformation and production process, and intelligent material delivery during station production process of the whole line. The functions are described in details as follows:

1.Autogenous welding of shelf and edge steel

After completing splicing of shelf and edge steel, the frames shall undergo welding process, which is the most core process during the shelf processing, and it decides quality of shelfs directly. Manual welding is traditionally adopted, which has poor quality uniformity and great labor intensity, and the noise, strong light and dust, etc. can cause pollution to the welding personnel and environment, therefore, digital shelf processing line adopts robot laser welding process to replace original manual welding.

Automatic welding of shelfs adopts laser tracking principle, and follows the laser triangulation measurement principle: three parallel laser beams project onto the surface of the base material at a slant angle of 20 degrees, and generate deformation on splicing edge of the weld; in the meantime, a digital camera is used to scan the work area, collect and process the data of laser rays, thus determining the weld location.

By virtue of this welding method with automatic tracking and stable output current, it has solved the industrial difficult problems with manual welding of shelfs such as poor-quality uniformity, low efficiency, great labor intensity, severe pollution, as well as great difficulty and poor quality stability with automatic welding of Grade I shelf stainless steel weld.

2.chamber structure design

The cavity is shaped by an integral plate with rounded corners, and the whole cavity has only one welding joint. There is no risk of leakage.

3.The isolator, the freeze dryer and Sterilizing & drying tunnel are connected by full-length welding process, which have no risk of leakage, and do not require regular maintenance.

4.Shelf welding by vacuum brazing

At present, our company uses vacuum brazing for welding of shelfs. In the form of hollow square tube, it makes pot welding of the brazing solder to the hollow square tube, and then welds the square tube with the solder to the board, and uses crossers to have close contact with the board, places them in vacuum brazing furnace, and then connects the upper and lower boards with the square tube under vacuum and high temperature in accordance with the vacuum brazing process, and then upon completion of brazing, makes welding of surrounding places of the shelf. Compared with manual argon tungsten-arc welding and drilling plug welding methods, vacuum brazing has smaller welding deformation and quicker welding speed, as well as thinner board and better heat-conducting performance of the shelf.

5.Integrated cleaning and drying process of shelfs

During welding process of shelfs, the surface cleaning is a very important process. Poor cleaning will make it easy to cause poor welding quality, sand hole in the weld and other problems. Traditional cleaning process relies on artificial immersion and scrubbing, which is a waste of time and energy, besides, the residual water on the shelfs are difficult to dry, and the whole process will require 65min on average; however, in automatic welding process, integrated cleaning and drying process of shelfs is added, which is equipped with high-pressure spray nozzle and drying & heating tube, enabling the whole process to make thorough cleaning and quick drying; the operation speed of shelfs on the integrated machine is set at 25cm/min, and the whole process will take no more than 35min.

6.Double-motor station sander

Traditional sander only has one polishing station, and the board-layer undergoes polishing once only; while in automatic welding process, the polisher has two polishing stations, which can enable the board-layers to undergo back-and-forth polishing in the sander, thus having higher production efficiency.

7.Intelligent digital online testing

Upon completion of sanding, the board-layer shall undergo flatness test and roughness test. After passing the flatness test and roughness test, the board-layers shall be off the line by stacking, and then processing of board-layers is completed.

8.Automatic welding process technology of board-layers

Compared with traditional manual welding process, it has solved industrial difficult problems with board-layers such as the quality uniformity is poor, welding of Grade I board-layer stainless steel weld is of great difficulty and the welding quality is of poor stability, and has effectively improved overall quality of biological freeze dryer, and it is also equipped with obvious technology and cost advantages as follows:

1)The number of personnel configured for board-layer and edge steel welding process is reduced from 4 to 3, and the labor cost is reduced by 25%;

2)With breakthrough of process technology as well as reduction in welding time, cleaning time and polishing time, etc., production efficiency per day is improved by 50%;

3)Lump-sum leakage detection pass rate of board-layers is improved from 90% to 100%;
