The composition and working principle of the high-efficiency coating machine

The high-efficiency coating machine is a new type of equipment that integrates strong electricity, weak electricity, hydraulic pressure and pneumatics, and transforms the original ordinary sugar coating machine
.

It is mainly composed of the main engine (original sugar coating machine), the controllable normal temperature hot air system, and the spray system for automatic liquid supply and air supply
.

The main motor is variable frequency speed regulation, which uses the method of automatic electrical control to spray the coating accessories onto the surface of the tablet with a high atomization spray gun, and the tablet moves in a continuous and complex trajectory in the coating pot, so that the coating liquid is evenly distributed.
It is wrapped on the core of the tablet, and there is a controllable normal temperature hot air in the pot to dry the tablet at the same time, so that the surface of the tablet can quickly form a firm, dense, complete and smooth surface film
.

The composition and structure of the high-efficiency coating machine: 1.
The host is the main station of the coating machine.
The wrapping roller and the drum are composed of stainless steel sieve plates.
The door is equipped with a moving rod, and the rod end is equipped with an adjustable medium spray gun (10 type single spray gun).
, 80 type double spray gun, 150 type triple spray gun)
.

The spray gun is imported from Japan, with automatic thimble, wide fan shape, adjustable angle, and non-sticking
.

The main drive system of the drum is a frequency conversion speed control device
.

Hot air inlets and exhaust holes are arranged on both sides of the roll, and the air ducts are arranged at the first and second levels
.

The filter guarantees a hot air rating of over 100,000 into the studio
.

2.
The hot air blower is the heat source supply system of the host, mainly composed of axial flow fans, filters, stainless steel U-shaped heaters,
etc.

When the temperature is above 80 °C, the hot air required by the host is heated to above 80 °C through the heat exchanger, and the hot air must be sent to the drying room for production
.

　　3.
The dust removal and exhaust fan is composed of a centrifugal fan, an ash collection bag filter, and an ash collection hopper
.

Its main function is to make the wrapping roller form a negative pressure state through the work of the fan, and then discharge it through the non-woven bag after collecting ash, so that the external discharge can meet the GMP requirements
.

At the same time, the power of the dust exhaust fan is larger than that of the hot air fan
.

　　4.
The system programmable logic controller (PLC) is installed on the upper part of the coating host, which is a set of equipment and electrical control system

.

The constant temperature mixing barrel is made of imported stainless steel, which meets the requirements of GMP
.

The chip is in a clean and closed rotating roller, constantly doing complex trajectory motion, and turning over smoothly, from the spray gun to the chip, at the same time under hot air and negative pressure, the hot cabinet provides 100,000 clean hot air through the chip, through the bottom sieve hole, and then It is discharged from the valve, allowing the medium on the chip surface to dry quickly and build up the strength
