In fact, the vacuum automatic dispensing machine equipped with the "vacuum" refers to the vacuum pump, vacuum pump is a pump, the absolute vacuum in the real life and the environment is not exist, the general working environment can maintain the vacuum state is mainly realized by the vacuum pump. Automatic dispensing machine equipped with a vacuum pump does not exist to affect the normal work of the air, as everyone knows air exposed to the glue bubbles appear, eventually affecting the quality and effect of glue, through the vacuum pump can be pumped to affect the normal work of dispensing air, to ensure better adhesive products after use clean more. The vacuum automatic dispensing machine into the market after the response is very good, because many precision manufacturing industry needs to execute package task in a vacuum, air is an important factor affecting most of the production sectors, no vacuum packaging of clean air is a basic requirement of precision production line to achieve the function of automatic dispensing, helping them to perform more effective vacuum the adhesive work by adhesive products after sealing good, can guarantee that in the best condition in the city before. Because of these needs, the vacuum dispenser can also be applied to the packaging work of the food industry. Of course, the use of dispensing machine for food packaging has related protective measures to carry out, and can not be implemented as industrial production.
