Petri Dish Filling, Capping, and Film Packaging Production Line

This is a new generation of aseptic dispensing lines for plate culture media. We can design aseptic dispensing production lines with different functional modules to suit your production capacity requirements, factory conditions, and the different industries where the culture media is applied.

This new generation product utilizes servo technology in key adjustment parts, facilitating digital control and memorizing parameters for different sized petri dishes, making it simple and reliable.

Models with 4, 6, 8, 10, and 12 channels can be designed to meet your production needs. Different opening, closing, and collection technologies are employed depending on the type of petri dish to meet the market demand for various sizes.

Class 100 laminar flow hoods (HEPA) and FFUs can be configured according to customer process requirements.

The main body of the dispensing line equipment is made of stainless steel SUS 304#, SUS304 aviation aluminum, aluminum alloy, and non-toxic polymer materials. Parts in contact with liquids are made of pharmaceutical-grade polymer materials or 316L stainless steel. The entire production line equipment meets GMP requirements.

The pre-filled petri dish automatic filling production line consists of automatic box placement (left and right stacking of dishes), automatic filling, automatic shaking (bottom pre-cooling with cooling plate, natural cooling, automatic capping, automatic box stacking, automatic packaging, etc.);

(1) Automatic box placement: The boxes are stacked and placed into a multi-channel positioning fixture. The vacuum suction cup robot automatically places the boxes. The box placement speed is fast and the operation is stable. Different boxes require additional box placement mechanisms to avoid adjustment.

(2) Automatic filling: A peristaltic pump filling system is used. Petri dish filling machine speed is fast, the filling volume is adjustable, and the accuracy is high. It can meet the filling needs of different quantities, greatly improving work efficiency. At the same time, medical-grade silicone tubing is used, which is durable, clean, and easy to disassemble, clean, and disinfect.

(3) Automatic shaking and pre-cooling: The automatic shaking device makes the dishes more uniform. At the same time, the bottom is a cooling plate to pre-cool the bottom of the dish in advance, thereby shortening the natural cooling time.

(4) Natural condensation tunnel: A Class 100 laminar flow hood is used. The packaged petri dishes run slowly in a sterile environment until they reach a solidified state before being capped.

(5) Automatic capping: After the petri dish boxes are filled with a certain amount of liquid and dried, they enter the automatic capping section. The positioning device in the capping section precisely positions the liquid-filled and dried boxes. A robotic arm equipped with a vacuum suction cup automatically caps the boxes, resulting in fast capping speed and stable operation;

(6) Automatic box stacking: The capped petri dish boxes are automatically transported to the automatic box stacking station. A precise positioning system automatically stacks the boxes via a servo system;

(7) Automatic Packaging: Stacked petri dish boxes are automatically flipped by an automatic flipping mechanism and placed flat into a pillow-type packaging machine. This results in excellent packaging quality, a smooth product surface, and sharp, well-defined sealing edges, allowing for continuous packaging. Petri dishes typically use solid culture media to prepare agar plates (hence the name “plate dish”). To prepare agar plates, pre-filled sterile agar medium is dissolved in warm (sterile) water. The cotton plug in a test tube is removed, and the tube opening is held over an alcohol lamp flame. The sterile petri dish lid is then slightly opened, allowing the test tube opening to penetrate deeply. The culture medium is poured in, and the plate is then sealed tightly. The plate is then gently shaken to ensure even distribution and solidification on the bottom of the dish, resulting in the agar plate.

Features: The main structure is made of high-quality SUS304 stainless steel, and the molds are precision-manufactured using 6061-T4 material. The equipment meets medical-grade standards, featuring advanced design, reasonable structure, excellent sealing, corrosion resistance, and durability.

Surface Treatment: Brushed surface finish; corners and welds are rounded; the outer magnesium alloy is electrolytically treated to prevent oxidation.
