The production process of efficient coating machines

The efficient coating machine can achieve automatic control of the sugar coating process, which is one of the advantages compared to the water chestnut type coating machine.
The process of sugar coating is more complex than that of film coating, and there are many process parameters that need to be controlled. Different process parameters need to be set for each stage of feeding, preheating, mixing, single syrup, color syrup, polishing, cooling, and discharging. Due to the many unstable factors in the sugar coating process, it is required that operators be allowed to make corrections during the automatic control process. Therefore, human intervention should be allowed in the program control, and the coating process should be uninterrupted.
Before setting process parameters, it is necessary to explore the process parameters and preset them into the control system. Before each coating, the operator only needs to call the corresponding control program. Appropriate control parameters can reduce the probability of contact between operators and drugs during the coating process, reduce the number of manual interventions, and ensure the stability and consistency of the coating quality of different batches of tablets. This mocks the dependence of sugar coating quality on operators in the past. The automatic control of the sugar coating process can also reduce the quality differences between batches caused by different operating habits of operators. These all meet the requirements of GMP and are one of the main characteristics of the drum type high-efficiency coating machine that is superior to the water chestnut pot type coating.
Through experiments and actual production, it has been proven that using a drum type high-efficiency coating machine to package sugar coated tablets has shortened the coating time by 20% to 40% compared to the water chestnut type coating machine, and the production capacity of a single pot is 3-4 times that of the latter. This means that the production capacity of a single equipment has reached 4-6 times that of the water chestnut type coating machine, solving the problem of mass production of sugar coated tablets. The surface quality of coated tablets is equivalent to that of sugar coated tablets packaged by a water chestnut type coating machine.
