The importance of cooling

At the beginning of this blog, we tried to let everybody knows the importance of cooling. Decades years before, the food industries use hot filling to pack the food, this is because filling in the high temperature will restrain the growth of bacteria.

As the books say, the bacteria grow so fast in the temperature 20°C to 70°C. At that time, there was no such kind of technology of instant cooling machine, so the hot filling is the correct filling method.

Now there is still no exist 100% heat-resistant plastic bag. Filling in high temperature may cause some toxins release by the plastic bag. As instant cooling machine has been invented, cold filling will be the correct filling method with less risks.

The key point of cold filling:

1. Clean room.

2. What's inside the clean room?

• air conditioner: to keep the clean room temperature under 18°C, and dehydration the room.
• air filter: one clean room needs 2 air filter, and put them in the opposite angle. To clean the air of clean room.
• disinfection before enter the room: normally we use 75% of alcohol with 25% of water to disinfect the room.
• wear the clothes, masks, hats, gloves, and shoe which located inside the clean room. This is because we may bring the bacteria inside when entering into the clean room.
