Introduction：

Model DDC Continuous Coating Machine is used for continuous feeding, coating and discharging of tablets according to the required output. It has the ability to vary batch sizes according to product requirements and demand, which can effectively save production cost and time, reduce energy consumption, and increase production efficiency.

Working Principle：

DDC continuous coating machine adopts continuous tablets feeding and discharging. Using a precision weighing and conveying device, the tablets continuously produced by the tablet press are fed into the inlet of the coating machine. The tablets in the drum continuously and orderly flow from the front end of the drum to the rear end of the drum under the control of the drum rotation speed and axial baffle. The tablets gradually form a uniform film and dry to gain weight under the cover of the atomized coating liquid sprayed by multiple sets of spray guns. After passing through the last set of spray guns, the target weight gain is achieved, making the film of the tablets uniform and firm. The completely dried coated tablets are discharged from the outlet to the collection drum or bag. The tablets are then cooled by a tunnel cooler or directly transported to a pack­aging machine for continuous packaging production. It realizes the continuous production in pharmaceutical coating process, and is particularly suitable for large batch size coating.

Features：

■ Continuous production, especially for large batch size
■ Switch between batch production mode and continuous production mode
■ Flexible product volumes
■ Reduce material handling
■ Washing in place
■ Fully automatic process
■ Better coating uniformity
■ Shorten production cycle times and improve productivity
■ Less floor space and utilities

Spray gun features

■ Anti-bearding design
■ Uniform spray rate to ensure uniform tablet weight gain and tablet thickness
■ Easy to maintain

■ Alloy spray gun rod, light and tough

Tunnel Cooler

■ The temperature of coated tablets is greatly reduced in a short time by cold air passing through the material layёr

■ The tunnel cooler is provided with cold air from the air inlet cabinet

■ This machine can prevent the influence of high core temperature on tablets

■ CIP cleaning in place

WIP

The continuous coating machine has a simple internal structure. The reasonable washing design makes the washing effect of coating machine in place very significant, which can fully meet the standard of cleaning validation.
