If you want to manufacture different pills for different purposes, at a small or large level, you can get a pill press. But before opting for this machine, you have to better understand its working mechanism as well as its usage. In order to get comprehensive knowledge about this machine, read this guide.
Let’s move onto it:
Definition of Pill Press
A pill press is a machine that operates by compressing powder into a tablet. Therefore, it is also known as a tablet compression machine. Many products, including candies, mooncakes, and pharmaceutical pills, are prepared with this machine.
Parts of Pill Press
The pill press consists of mainly 3 parts, including the transmission part, the pressurizing part, and the weighing part.
1. Transmission Part: There are two components in this part: the feedure, which takes the granular material to the second part that dies, where the tail over ensures the exact amount is regulated before moving to the next stage.
2. Pressurizing Part: This part of the machine consists of punches, which ensure a symmetrical pressure mechanism. There are upper and lower punches; the upper punches apply pressure to the lower punches . There are two compression rolls too, and the punches move upward and downward with the help of four cams. This movement compresses material and ejects final pills.
3. Weighing Part: It’s the last part of the machine with two components, which are weight adjustment and weight control. One ensures sufficient granular material is there and the next check is that uniform weight is transferred across all dies.
Working Principle of Pill Press
A tablet press machine not only compresses powder into tablets; in fact, it follows a complete procedure. The process ensures the quality and uniformity of tablets. Here it’s a complete principal:
- First, the raw material of the tablet is prepared because simple powder could not hold together well. Some inactive substances are added. In the second phase of this process, the granules are formed in the fluid bed granulator or mixer. Their main aim is to form granules that stick together after compression.
- These granules are not yet ready to form tablets; further, some liquids are added to extract impurities and then dried in a drying machine. After this, the pure, dried mixture is fed into the tablet press. Here, furthermore, powder is usually mixed until the weight control unit ensures that each die cavity is filled with the same amount of mixture.
- In the third phase, compression is done; when dies move, pre-compression and main-compression rolls do their work. They apply significant pressure so that granules could be transferred into tablets.
- In the last phase, the tablet is ejected as the upper cam raises upper punches and the ejection cam pushes the tablet out of the die. There, a scrapper collects the tablet and thus, the process is completed.
Advantages of Pill Press
- This machine is able to manufacture thousands of pills in an hour. This is why it has great efficiency.
- The machine is able to control the size of pills precisely, which ensures the quality of products.
- All tablets that are ejected from one product are identical to ensure patients safety.
- Pill presses follow the strict regulations and processing standards to form safe pills or tablets.
Types of Pill Press
There are mainly 2 types of pill presses; let’s elaborate on them.
Single-Punch Tablet Press: This is a machine usually used at small levels, like in laboratories, to produce tables like Ca or sugar tablets. These are simple to operate and portable too. It usually comes automatically, which needs just a plugin to operate. But the main limitation of this machine is that it can shape only one tablet at a time. Tablets in large quantities are usually not prepared with this machine because it loses powder behind as waste, which is a big concern to form large amounts of tablets.
Rotary Tablet Press: This machine is larger and faster than a single punch machine and comes in high-speed, sub-high-speed and fully automated form. This machine can work very smoothly and perform stable operations. Usually it is used in pharmaceutical industries for tablet’s production. There is a suction box that collects the dust and prevents blockage. That is why the raw material could be recycled.
Applications of Pill Press
This machine is used for a variety of applications in multiple industries, especially to produce different types of tablets and capsules. Let’s see some of its applications.
Pharmaceutical Industry: In pharmaceutical industries, this machine is mainly used to create capsules. The size of capsules is so adjusted, which could be convenient for patients. It is ensured that patients can easily swallow them or can encapsulate the powder or oils.
Engineering and Tablet Experiments: In the engineering department, this machine is used to experience tablet production. This machine can test the materials and techniques, which could be improved for the sake of the tablet’s quality.
Glass and Herbal Industries: This machine is used in industries where herbal products are manufactured. Here it can produce tablets or capsules that contain herbal extracts. This machine is also used in the glass-making process.
Chewable Tablets: Chewable tablets are also made up from this machine. These tablets contain sweetener, lubricant, and binder. These are designed for children or people who don’t like pills to swallow.
Effervescent Tablets: effervescent tablets are those that are mixed in water; these release carbon dioxide and create bubbles. A pill press machine is used to manufacture those tablets because it can mix the ingredients properly, which are tartaric acid, citric acid, and sodium bicarbonate.
Surface Hardness Variability: This machine is able to adjust different levels of hardness, therefore used to make a variety of tablets. This is important because different tablets require different hardness level based on their purpose and their solubility in the body
Conclusion
You can opt to press the pill press to form the tablet’s formation from a power. Its usage in various industries rather than pharmaceuticals enhances its value. With the help of this instrument, you can get an efficient and uniform tablet. This machine can also let you know if any ingredient is missed.
