Introduction of continuous film coating and sugar coating machine
November 29, 2022
Pharmaceutical manufacturers often want production lines and equipment to run continuously, while traditional continuous-running coating machines often have such problems, the operation process is short, and there is great inaccuracy. This paper introduces a new coating process that combines continuous operation with batch processing.
Conventional continuous-running coating machines often have such problems, the running process is short, and there is great inaccuracy. In addition, the coating of the coating is very thin, because the running time of the machine is limited and some simple pre-processing is required. For this reason, the coating machine needs to install a batch processing program to ensure that the product is finished after the product is finished. The disadvantage is that a lot of loading and unloading procedures are required and the product is subject to mechanical influence. This often requires the use of relatively smaller batch coaters.
It is desirable to eliminate these shortcomings in the development of continuous running coaters, while at the same time converging the advantages of continuous and batch processes into one system. “We want to meet the requirements of pharmaceutical manufacturers to enable them to produce qualified drugs and over-the-counter drugs in large quantities.” The technical director of Driam Machine Manufacturing in Eriskirch described the situation at the beginning of Zui and pointed out the related processes. “Pelletization is a similar process, and tableting is ongoing.”
This is technically the case where the material is transported through a coating pan that is divided into different compartments. The pill is placed in the compartment for a certain period of time, then sprayed with a sugar solution and the pill is transported to the next compartment. The product is sent from the first compartment to the second compartment, and then from the second compartment to the third compartment, and so on. This allows the drug to be processed in a quality and quantity, resulting in a combined machine that combines the advantages of continuous and intermittent coaters.
The machine will be customized according to the process technology to ensure the high quality production of the product. The basis for the development of a new machine is usually a wide range of tests carried out on a technical machine, the machine must be able to carry out production tests in the original production scale.
Candy coating
Take the confectionery industry as an example to show how machines operate in production practice. 1200 kg of product per hour is produced in seven different production steps, where machine accessories with weak soft and compressive capacity will be placed on a 50 kg share line and shipped to compartment 1; after three minutes of operation, the product will Shipped to the second compartment. Then start * production steps - spray colored syrup and sprinkle with sugar. After another three minutes, the product will be transported to the next compartment, where processing will continue. In the eleventh compartment, two layers of fudge will be applied, and then a thin layer of wax will be sprayed on the zui. After the end of a compartment machine after zui, the products will be collected, extracted through a vibrating chute and installed in the finished container.
The dosage of the sugar coating is very important for the production of high quality products, and the basis for ensuring accuracy is the weighing tool in the metering system. The storage container will automatically fill up through a horizontal control system. An exhaust device with a built-in air filter will regulate and dedust the air in the coating pan to reduce dust contamination in the production environment.
The coating machine is operated by a touch screen. The software is specially designed for this type of machine. All doses and speeds can be selected. In order to meet the hygiene standards of the confectionery industry, the machine is also equipped with an automatic cleaning system. For ease of inspection and cleaning, the dosing system will completely withdraw from the coating pan.
Tailored for the pharmaceutical industry
The Driaconti-TPharma coating machine is specially developed for the pharmaceutical industry. For the continuous operation of the coater, a powerful air handler was installed and a separately operable spray system was installed in each compartment. This type of machine requires special attention in terms of cleaning. For this purpose, both sides of the coating pan, the coating pan itself and the air handler components must be separately detachable.
“We believe that manufacturers of high-volume and over-the-counter drugs will need our products.” Grabherr pointed out possible applications for the coating machine. “The quantity and size required for each production compartment demonstrates its power, starting with 40 kg per hour.” Driaconti-TPharma can be used alone or in combination with other machines. All traditional tablets or other forms of medicine can be coated. Such a machine meets the requirements of a continuous operation program on the * line, thereby ensuring the high quality of the product.
