A pass window Pass Box concept
As an auxiliary equipment of the clean room, the transfer window is mainly used for the transfer of small items between the clean area and the non-clean area, so as to reduce the number of times the clean room is opened, and the pollution of the clean area is greatly reduced. Transfer windows are widely used in micro-technologies, biological laboratories, pharmaceutical plants, hospitals, food processing industries, LCDs, electronics factories, and other places where air purification is required. The transfer window is made of stainless steel and is smooth and smooth. The double doors are interlocked to each other to effectively prevent cross-contamination. They are equipped with electronic or mechanical interlocking devices and equipped with ultraviolet germicidal lamps.
Classification of two transfer windows
The transfer window is divided into three categories:
1 electronic chain transfer window
2 mechanical chain transfer window
3 self-cleaning transfer window
According to the working principle, the transfer window can be divided into a shower room transfer window and a normal transfer window and a laminar flow transfer window. Various types of transfer windows can be made according to actual requirements.
The transfer window can be divided into: ordinary transfer window and air shower transfer window according to whether there is purification function.
The similarities and differences between the ordinary transfer window and the air shower transfer window:
A. The transfer window and the air shower transfer window are mainly used for the transfer of small items between the clean area and the clean area, the clean area and the non-clean area, so as to reduce the number of opening of the clean room, and the reduction of the cross between the clean areas is greatly reduced. Pollution.
B. The transfer window and the air shower transfer window can be divided into: an electronic interlock transfer window and a mechanical interlock transfer window according to different interlocking modes. The transfer window doors are double door interlocks.
(That is, only one door can be opened at a time. After opening one door, the other door cannot be opened.)
C, the transfer window and the air shower transfer window can be divided into: stainless steel transfer window, stainless steel transfer window in the outer steel plate, etc. according to the material of the box. Commonly used plates for transfer window production include cold-rolled steel sheets (A3 sheets) and stainless steel sheets (SUS201, SUS304, SUS316, etc.). The thickness is generally 0.8 to 1.5 mm. (Transmission window fabrication belongs to thin-plate welding, which requires high welding technology and grinding technology for welders. The transmission window liners are all sanded stainless steel. The cost of different material transfer windows is different.)
D. At the top of the air shower transfer window, four air shower nozzles are arranged with a fan and an initial high efficiency filter on the inner side of the box, and the ordinary transfer window does not have this self-clean function configuration. Optional accessories: walkie-talkie, germicidal lamp and other related functional accessories.
Three transfer window features

4 According to customer needs, we can customize all kinds of non-standard size and floor-standing transfer windows.
5 Wind outlet air outlet speed is up to 20s.
6 The filter has a high efficiency filter with a filtration efficiency of 99.99% to ensure the purification level.
7 EVA sealing material with high sealing performance.
8 can be paired with walkie talkie
How the four transfer windows work
1 Mechanical interlocking device: The internal interlocking is realized by mechanical means. When one door is opened, the other door cannot be opened. The other door must be closed before another door can be opened.
2 Electronic interlock device: internal use of integrated circuit, electromagnetic lock, control panel, indicator light, etc. to achieve chain, when one of the doors is open, the other door open indicator light does not light, telling that the door can not be opened, and the electromagnetic lock The action is chained. When the door is closed, the other electromagnetic lock starts to work and the indicator light illuminates, indicating that the other door can be opened.
The composition of the five transfer windows .
1 all stainless steel transfer window 2 ultraviolet germicidal lamp 3 buzzer 4 walkie talkie 5 electronic interlock
Ready-to-eat Single Packed Sweet Corn
The factory is located in Gongzhuling City which known as "Hometown of Corns in China", it is one of the top three golden corn belts in the world far away from pollution.
Jilin Province, as the main corn producing region in China, is also in the main grain exporting province of the country. It has been the first in China in terms of total corn production and commercial grain rate. There has the mosst excellent soil and climate which are suitaable for corn growth. The corns there have high yield and excellent quality, are ideal raw materials for processing fresh sweet and waxy corn.Corn planting in the Northeast region is mostly one crop a year, and spring sowing is mainly based on clearing, which accounts for more than 50% of the corn planting area in the Northeast.
In addition to clearing, the importance of corn in crop rotation cannot be ignored. Rotate crops with sorghum, millet, soybeans and other crops to improve crop yields.
Affected by climatic characteristics, the choice of corn varieties in Northeast China is to choose varieties with moderate maturity or early maturity, and at the same time have the characteristics of low temperature tolerance and high yield.
