The vacuum filling machine is a push pull cap machine for filling under the pressure in the bottle is lower than atmospheric pressure. It uses continuous vacuum suction to draw the product into the container. Its continuous suction is connected to a vacuum chamber and a special filling valve. The vacuum pump is generated. The general process is as follows: boxes with empty bottles are stacked on a pallet, which is sent to a pallet unloader by a conveyor belt, and the pallets are unloaded one by one. The boxes are sent to the unloader with the conveyor belt to remove the empty bottles from the box. The empty box is sent to the box washing machine through the conveyor belt, after being cleaned, and then transported to the boxing machine, so as to load the bottle containing the beverage into it. The empty bottles taken out of the unboxing machine are sent to the bottle washing machine by another conveyor belt for disinfection and cleaning.
After being inspected by the bottle inspection machine, they meet the cleaning standards and then enter the filling machine and capping machine. Drinks are filled into bottles by the filling machine. The bottles filled with beverages are capped by the capping machine and transported to the labeling machine for labeling. After labeling, the bottles are sent to the cartoning machine to be loaded into the box and then sent to the pallet stacker to be stacked on the pallet and sent to the warehouse. The contents of the airless bottle can be completely isolated from the air, to prevent the product from oxidizing and degrading due to contact with the air, and breeding bacteria, and to upgrade the product level with its high-tech concept. Vacuum bottles commonly used in the market are composed of a cylindrical ellipsoid container and a piston placed at the bottom.
Its design principle is to use the contraction force of the spring, and not allow air to enter the bottle, causing a vacuum state, and use atmospheric pressure to push the piston at the bottom of the bottle forward. However, because the spring force and atmospheric pressure cannot give enough force, the piston cannot be too tightly attached to the bottle wall, otherwise the piston will not be able to advance due to excessive resistance; otherwise, if the piston is to advance easily and it is prone to leakage, Therefore, the vacuum bottle has very high requirements on the professionalism of the manufacturer. The modern thermos was invented by British physicist Sir James Dewar in 1892. At that time, he was conducting a research work to liquefy the gas.
To liquefy the gas at a low temperature, first of all, he needed to design a container that can isolate the gas from the outside temperature, so he asked the glass technician Berg to blow a double Multi-layer glass container, coated with mercury on both inner walls. Then evacuate the air between the two layers to form a vacuum. This kind of vacuum bottle is also called "du bottle", which can keep the liquid contained in it unchanged regardless of the temperature and temperature. Since the thermos is mainly used for hot water insulation in the home, it is also called a thermos. The structure of the thermos is not complicated. In the middle is a double-layer glass bottle, which is evacuated between two layers and plated with silver or aluminum. The vacuum state can avoid thermal convection. The glass itself is a poor conductor of heat, and silver-plated glass can reflect the heat energy radiated outward from the inside of the container. Conversely, if cold liquid is stored in the bottle, this bottle can prevent the external heat energy from radiating into the bottle.
