Let us proceed and look at the working principles of the dry syrup filling machine in the next section.

How to Dry Syrup Powder Filling Machine Works

Well, from the previous section, you already know that there are different types of dry syrup powder filling machines.

Implying that the working principles of these machines may differ accordingly.

In this section, we are going to look at the working principles of an automatic rotary dry syrup filling machine.

· Step 1: Preparing Powder Syrup

You need to have uniform concentrates of the ingredients that you will require for preparing the powder syrup.

The uniform concentrates will ensure that the dry syrup does not break into a non-homogenous mixture during the reconstitution process.

The ingredients that you will need in the preparation of powder syrup include:

i. Excipients for stabilization of ingredients

ii. Granule Disintegrates helps in reducing aggregation during the reconstitution process

iii. Granular Binder ensures the dry syrup particles settle in the suspension

iv. Powder Blends

v. Coloring agents, sweeteners or flavor

The process begins with weighing, dispensing, and sieving at different stages to ensure a homogenous powder.

You will transfer the mixture to a drum mixture where it will mix the whole mixture in two steps.

The first step involves mixing with a key excipient that will ensure proper dispersion.

The second step involves mixing the other excipients that are sensitive to heat such as flavors.

From this stage, you will transfer the complete mixture of the dry syrup powder to the filling machine.

· Step 2 Preparing Powder Syrup Filling Container

Before loading the powder mixture into the filling machine, you need to prepare the syrup filling container.

The container can be a plastic or a glass bottle depending on the filing requirements.

You can either decide to purchase the containers from a different supplier or make them yourself.

The containers can also be of different shades and shapes depending on the dry powder syrup that it will hold.

Well, with the containers in place, let us look at how you will clean these containers.

· Step 3: Sterilizing/Cleaning Syrup Powder Filling Container

You have to clean and sterilize the syrup powder filling container to ensure that it does not have any contaminants.

Contaminants may compromise the integrity of the dry syrup powder so you have to get rid of all of them.

You can use different cleaning and sterilizing agents such as hot water that will kill all the germs.

Make sure that the container is dry and does not have any liquid to prevent early reconstitution of the dry syrup powder.

· Step 4: Loading Container for Dry Syrup Filling

After cleaning and sterilizing the containers, you can load them onto the dry syrup filling machine.

This may be the last task that you will perform using your hands.

From this point, the machine will pick the containers through the infeed turntable.

The infeed turntable will guide the containers to a flat conveyor belt moving at a certain speed.

The container moves on the conveyor belt to the feed worm for the right spacing.

It reaches the feed star wheel which will transfer the bottles and position them properly below the funnels.

Since we are using an automatic rotary dry syrup filling machine, it can either have 12 or 16 funnels.

At this point, the containers are in a position to receive the filling powder.

· Step 5: Filling Container with Dry Syrup

The machine has a lifter assembly that will lift the containers and fit them perfectly under the funnels.

As this continues, you will load the dry syrup powder from the powder mixer on to the powder hopper.

Before loading the dry syrup powder, make sure that it passes through thorough sterilization.

In the powder hopper, mechanical agitators, agitate the powder to ensure that it maintains uniform bulk density and uniformity.

At the same time, the powder wheel rotates gently below the powder hopper.

The powder wheel then determines the amount of dry syrup powder to fill into the containers.

It follows the specifications that you enter and fills the containers through the powder filling head and funnel.

Time dose sterilized compressed air assists in pushing the dry syrup powder into the containers.

The machine fills all the bottles in approximately 5 to 6 seconds before lowering the full bottles.

It gives space for filling more containers and the filling process continues.

The full bottles proceed on to the inspection stage.

· Step 6: Inspecting Filled Dry Syrup Container

With the help of an inspection machine, you have to ensure that the containers contain the right amount of syrup.

In case of any wrong miscalculations, the machine will reject the container with the contrary specifications.

It will allow the perfect containers to proceed to the capping and sealing stage.

· Step 7: Capping Container Filled with Dry Syrup

At this point, the machine will place a cap on every container.

Most containers have standard sealing so you should not worry much about getting caps.

The machine screws the caps on the bottles tightly and seals them properly.

The seal will make the bottle tamper proof and block any contaminants from entering the container.

· Step 8: Labeling Dry Syrup Containers

The container is never complete without a label.

The label will inform you and other end users of the components of the dry syrup container.

It will also give ingredients and the instruction on how to use the dry syrup among other important specifications.

Speaking of specifications, let’s have a look at the key specifications that you will look at before purchasing the machine.
