A rainbow coating machine is a kind of coating machine that applies different color patterns on the capsule, tablet, or other products' surfaces. Here are some types of rainbow coating machines.
Electromagnetic rainbow coating machine
The machine changes the capsule or tablet's color by changing the electromagnetic field strength within the equipment. It provides flexibility for businesses to customize coating colors and patterns but is a more costly option.
Drum-type rainbow coating machine
This machine uses the revolving drum to itemize and spray coating substance onto the surface of the item. This coating method provides an equal application and is appropriate for use with various coating liquids.
Rainbow Airflow Coating Machine
This device employs airflow to transport coating solution droplets to the surface of items. Typically, it has adjustable spray nozzles and airflow control, allowing uniform color application over a wide area. It is good for small-scale production. The machine may use one or more spray nozzles to uniformly apply the coating material to the item. The spray nozzles may be adjustable to change the size and shape of the spray pattern. The items may be tumbled or rotated to expose all surfaces to the coating.
Rainbow Spray Coating Machine
This device uses a spray gun to apply the coating substance to the product's surface. It can offer a gradient of colors and is suitable for large-scale manufacturing.
Rainbow coating machines have different specifications depending on the manufacturing companies and the intended uses. Generally, the machines have a production capacity that ranges from 500 g to 2000 kg of coated pills per hour. The machines are designed to work with pan diameters that range from 30 mm to 900 mm. The speed of the machines is adjustable, and they rotate at speeds of 5 to 50 rpm. The temperature settings of a coating machine are usually between 60 °C and 80 °C. The power requirement for the machine varies depending on its size and motor, but it is usually between 0.55 and 3 kW. The spraying pressure for rainbow coating machines is between 0.3 to 0.7 Mpa.
For the Rainbow Coating Machine to perform efficiently and effectively, maintenance is necessary. Regular maintenance checks should be performed on the machine to identify any underlying issues and fix them promptly. The machine should be cleaned regularly after coating is done to prevent the buildup of residue. The cleaning can be done using warm water with a neutral detergent. Manufacturers of coating machines advise businesses to briefly spray the machine with water and detergent solution and run it while still sprayed to clean the inner parts effectively. Rinse thoroughly with clean water and let the parts dry.
The lubricated parts of the machine should be lubricated regularly to reduce friction and prevent fast wear. The loose parts of the coating machine should be tightened regularly to ensure stability and safety during operation. Rainbow coating machines have safety features such as emergency buttons and covers. The safety features should be inspected regularly to ensure they are working as they should. Rainbow coating machines require periodic professional maintenance. The machines should be inspected and calibrated by a professional to ensure they are working appropriately and all the settings are accurate. When setting up the coating machine for use, ensure it is on a level ground to prevent shaking during operation.
The rainbow coating machine has numerous applications across different industries. Below are some of the key use scenarios:
Pharmaceuticals and Nutraceuticals
Rainbow film coating machines are primarily used in the pharmaceutical and nutraceutical industries to coat tablets with a desirable coating formulation. Coating tablets with a rainbow coating machine offers benefits such as masking undesirable tastes and smells, making swallowing easier, and protecting tablets from environmental factors like moisture, oxygen, or light. Additionally, rainbow coating machines can be used to control the release pattern of drugs by modifying the tablet's dissolution and Ingestion behavior.
Food Industry
In the food industry, rainbow coating machines are often used to create coated food products like nuts, candies, and chocolate.
Rainbow coating machines apply protective coatings to enhance the shelf life and quality of food products. They also improve the flavor, texture, and appearance of coated food products.
Herbal Medicine and Functional Food
Rainbow coating machines can be used to coat herbal medicine and supplements with protective and masking coatings. The coatings applied by a rainbow coating machine can protect sensitive ingredients from degradation and release them in a controlled manner.
Confectionery and Snacks
Rainbow coating machines are often used in the confectionery and snacks industry to create a coated product like candies, pills, and coated snacks.
Using a rainbow coating machine to coat confectionery products offers numerous benefits, such as improving the shelf life, adding flavors, and enhancing the product's visual appeal.
Agrochemicals
Agrochemical formulations such as fertilizers and pesticides utilize rainbow coating machines to enhance their stability, improve handling properties, and control release patterns.
