Briefly describe the process flow of coating by pharmaceutical coating machine

Pharmaceutical coating machine is mainly used in the pharmaceutical and food industry, is a tablet, pill, candy and other packaging icing, organic film, water-soluble film with high efficiency, energy saving, safety, clean, easy to operate a new type of coating equipment
.

The housing of the equipment, the coated drum (coating pot), the hot air cabinet, the spray device and all parts in contact with the pharmaceutical are all made
of stainless steel.

Pharmaceutical coating machine product features: The entire process operation process is controlled by the microcomputer processing programmable system, and can also be controlled
manually.

The control system has functions
such as applications, multiple operating state selection, drive control, and multiple displays.

For organic solvents in the process of coating organic films, there are explosion-proof measures
.

Closed operation, no dust flying and liquid splashing
.

Film coating can be sprayed continuously and simultaneously with coating medium, drying, exhaust, only 1-2 hours to complete the entire coating process, sugar coating only needs to be completed
in four to five hours.

Equipped with an automatic feeding and unloading device, the core can be automatically added to the drum or automatically discharged
.

The process flow of coating by the pharmaceutical coating machine: the material is added to the hopper of the fluidized bed, and an upper and lower end openings are added to the hopper and the corresponding sieve plate with different opening rates is added to the hopper to control the movement of the material to form an orderly fluidized state
.

The spray is added to the system through an aerodynamic nozzle mounted in the center of the sieve plate in the same direction as the
material movement.

There is a certain spacing between the partition ring and the sieve plate to ensure that the material can flow smoothly from outside the partition ring to the inside of the partition ring, forming a cyclical flow state
.

The coated particles pass through the trap and begin to slow down
in the expansion chamber.

When the particles rise to the expansion chamber, the excess medium is evaporated, and when the air velocity cannot push the particles to move, the particles fall back into the gap between the spacer and the hopper, where the air flow is sufficient
as long as the particles can move downwards and maintain a weightless suspension state.

The particles move horizontally from the area between the spacer and the hopper wall to the coating area, forming a motion cycle, which is achieved by correctly adjusting the gap between the bottom of the spacer and the sieve plate, and the particles pass through the coating area in a few seconds, completing a motion cycle
.

After the sprayed coating liquid comes into contact with the pellet core, under the thermal action of dry air, the moisture in the coating fluid evaporates, and the pellet core is sprayed, and finally the coating pill
that meets the standard is obtained.
