The use of the transfer window Shanghai Sujing

The transfer window is an auxiliary device for the clean room. It is mainly used for the transfer of small items between the clean area and the clean area and between the non-clean areas of the clean area, so as to reduce the number of times the clean room is opened and reduce the pollution of bacteria. Although the window has the effect of sterilizing and reducing bacterial pollution, if it is not cleaned after a period of use, the bacteria that grow inside will not only play a role in sterilization, but also further contaminate the transfer substance in the transfer window. . Minimize the pollution of the clean room. The transfer window is made of high-quality stainless steel, and the surface is smooth and smooth. The interior is a circular arc structure for easy cleaning. Delivering goods is easy and convenient. The interlocking of the two doors effectively prevents cross-contamination, is equipped with an electronic interlocking device, and is equipped with an ultraviolet germicidal lamp, which is safe and simple to operate.

The transfer window is the transfer path for goods between areas of different cleanliness levels. It is a device that is installed between the clean room entrance and exit or different cleanliness level rooms to block the indoor and outdoor airflow when the goods are delivered, so as to prevent polluted air from entering the clean area and causing cross-contamination. Usually the transfer window is closed. The two doors use an electronic interlock. When the goods are to be delivered, the transmitter first opens the first door, closes the door immediately after the goods are delivered, and then opens a door when the other party receives the signal (the transmission window control panel is equipped with a signal indicator) to remove the material. Then close the door. When the power is on, the two doors cannot be opened at the same time.

When the transfer window conveys the cargo, the top part blows out the high-speed, clean airflow, blows off the dust particles on the surface of the cargo, and is equipped with an ultraviolet germicidal lamp inside, which can effectively kill the bacteria on the surface of the cargo. When the shower is complete, open another door to remove the cargo. The clean air flow acts as an air lock to ensure that the air outside the clean room does not affect the cleanliness of the room. The two side doors cannot be opened at the same time by electronic interlocking control, and special sealing strips are installed on the inner sides of the two sides to ensure the airtightness of the transfer window.

The materials entering and leaving the clean area must be strictly separated from the flow channel and accessed by the material channel of the production workshop. When the materials enter, the original auxiliary materials are unpacked or cleaned by the person in charge of the preparation process, and then sent to the temporary storage room of the workshop through the transfer window; the inner packaging materials are removed after the outer packaging is removed from the temporary storage. The window is sent into the inner compartment. The workshop integrator and the person in charge of the preparation and internal packaging process handle the material handover. When passing through the transfer window, the rules for "opening and closing" of the inner and outer doors of the transfer window must be strictly enforced, and the two doors cannot be opened at the same time. After opening the outer door, put the material into the door, then close the door, then open the inner door to take out the material, close the door, and so on. When the materials in the clean area are delivered, the materials should be transported to the relevant material intermediate station and removed from the clean area according to the reverse procedure when the materials enter. All semi-finished products are transported from the clean area and are transported from the transfer window to the external temporary storage room and transported to the outer packaging room via the logistics channel. Materials and waste that are highly susceptible to pollution should be transported from their dedicated transfer windows to non-clean areas. After the material enters and exits, the site and the window of the transfer station should be cleaned in time, and the inner and outer access doors of the transfer window should be closed to clean and disinfect.

Use the special cleaning cloth for the transfer window, disinfectant to clean the inner wall of the transfer window, the ceiling of each corner, the UV lamp tube, the transfer window door, etc., for the dirt accumulation thick, you can use the brush, disinfectant to clean the dirt, if necessary, use Disinfectant disinfection. It is sterilized by ultraviolet light during the use of the rust steel transfer window. It is a good habit to regularly clean the stainless steel transfer window. Disinfect the inside and outside of the window with disinfectant after use every week. After the stainless steel transfer window has been cleaned, after the professional inspector has checked and cleaned, the “cleaned” status indicator card will be attached to indicate that it can be put into normal use.
