Hey there! As a supplier of sugar coating machines, I'm super stoked to take you through the coating process flow in a sugar coating machine. It's a fascinating journey that turns plain pills or candies into those shiny, delicious treats we all love.
Step 1: Preparation
Before we even start the coating process, there's a whole bunch of prep work to do. First off, we need to get the cores ready. These cores can be tablets, pills, or even candies. They need to be clean and free from any dust or debris. We usually use a simple vibrating screen to sift out any unwanted particles.
Next, we have to prepare the coating solution. This is where the magic happens! The coating solution typically consists of sugar, water, and various additives like colors, flavors, and binders. The ratio of these ingredients depends on the type of coating we want to achieve. For example, if we're making a hard sugar coating, we'll use a higher concentration of sugar.
We also need to set up the sugar coating machine. This involves adjusting the speed of the drum, the temperature, and the spray rate. The drum is where the cores will be coated, and it needs to rotate at a specific speed to ensure even coating. The temperature is crucial because it affects the drying time of the coating solution. And the spray rate determines how much coating solution is applied to the cores.
Step 2: Initial Coating
Once everything is set up, we're ready to start the coating process. We load the cores into the drum of the sugar coating machine. As the drum rotates, the cores start to tumble around. At the same time, we start spraying the coating solution onto the cores.
The initial coating is usually a thin layer that helps to seal the cores and provide a base for the subsequent layers. This layer is important because it prevents the cores from sticking together and also helps to improve the adhesion of the other coating layers.
During this stage, we need to be careful not to apply too much coating solution at once. If we do, the cores may clump together, and the coating may not be even. We also need to monitor the temperature and humidity inside the drum to ensure that the coating solution dries properly.
Step 3: Build - Up Coating
After the initial coating has dried, we start applying the build - up coating. This is where we add multiple layers of coating solution to achieve the desired thickness and appearance. Each layer is applied one at a time, and we allow each layer to dry before applying the next one.
The build - up coating can take several hours, depending on the number of layers and the thickness of each layer. We keep spraying the coating solution onto the cores as the drum rotates, and we use a blower to help dry the coating. The blower blows hot air into the drum, which speeds up the drying process.
During this stage, we may also add different colors or flavors to the coating solution to create a more attractive and delicious product. For example, we could add a layer of chocolate - flavored coating or a layer of bright red color.
Step 4: Polishing
Once the build - up coating is complete, we move on to the polishing stage. Polishing gives the coated cores a shiny, smooth finish. We use a polishing agent, which is usually a wax or a shellac, to achieve this.
We add the polishing agent to the drum along with the coated cores. As the drum rotates, the polishing agent spreads evenly over the surface of the cores, creating a beautiful, reflective finish. This not only makes the product look more appealing but also helps to protect the coating from damage.
Step 5: Inspection and Packaging
After the polishing is done, we take the coated cores out of the drum and inspect them for any defects. We look for things like uneven coating, cracks, or chips. If we find any defective cores, we remove them from the batch.
Once the inspection is complete, the coated cores are ready for packaging. We can package them in various ways, depending on the customer's requirements. For example, we could package them in bottles, blister packs, or bags.
