How to make olive oil bottles?


1. Compounding material system

Including the storage, weighing, mixing and conveying of raw materials.

2. Melting

The melting of bottle and jar glass is mostly carried out in a continuous operation flame pool kiln (see glass melting furnace). The daily output of the horizontal flame pool kiln is generally more than 200t, and the large one is 400-500t. The daily output of the horseshoe-shaped flame pool kiln is mostly below 200t. The glass melting temperature is as high as 15801600. The energy consumption of melting accounts for about 70% of the total energy consumption in production. Energy can be effectively saved through measures such as overall thermal insulation of the pool kiln, increasing the capacity of the regenerator checker bricks, improving the distribution of the stockpile, improving the combustion efficiency, and controlling the convection of the glass liquid. Bubbling in the melting tank can improve the convection of glass liquid, strengthen the process of clarification and homogenization, and increase the output. The use of electric heating in the flame kiln can increase the output and improve the quality without enlarging the furnace.

3. Forming

The molding method is mainly used, and the small-mouth bottle is formed by the blow-blow method, and the wide-mouth bottle is formed by the pressure-blow method. Control laws are used less frequently. The production of modern glass bottles and jars widely adopts high-speed molding of automatic bottle making machines. This kind of bottle making machine has certain requirements on the weight, shape and uniformity of the gob, so the temperature in the feeding tank should be strictly controlled. There are many types of automatic bottle making machines, among which the determinant bottle making machine is more commonly used. This kind of bottle making machine gob obeys the bottle making machine, not the bottle making machine obeys the gob, so there is no rotating part, the operation is safe, and any branch can be stopped for maintenance alone without affecting the operation of other branches. The determinant bottle making machine has a wide range of bottles and cans, and has great flexibility. It has been developed into 12 groups, double-drop or three-drop molding and microcomputer control.

4. Annealing

The annealing of glass bottles and jars is to reduce the residual stress of the glass to the allowable value. Annealing is usually carried out in a mesh belt continuous annealing furnace, and the annealing temperature can reach 550-600 °C. The mesh belt annealing furnace adopts forced air circulation heating, which makes the temperature distribution of the cross section of the furnace uniform and forms an air curtain, which restricts the longitudinal airflow movement and ensures the uniform and stable temperature of each belt in the furnace.
