Simple and Rotary Compression Machine: What’s the Difference?
Do you know how the tablets and the candies are made? It is made by compression of raw materials like powders or granules. This is made possible by a tablet press machine. A tablet press machine produces tablets, pills, and candies by compressing granulated powder with high pressure. Tablet press machines are an important part of any pharmaceutical or food-made company producing tablets and candies in various shapes and designs. These tablet press machines work by compressing weight on the powder entered by a hole.
There are two types of tablet press machines that are very famous for their work in different sizes of productions – single tablet press machines and rotary tablet press machines. A single-punch pill press machine is ideal for small production areas using a single set of tooling, a die & a pair of upper and lower punches. On the other hand, a rotary tablet press machine is ideal for large-scale production, using multiple tooling stations that rotate to compress powder and form tablets. In this article, we will talk about the single tablet press machine and rotary tablet press machine. Let’s dive in.
Differences Between Single Punch and Rotary Tablet Compression Machines
Both of the machines work differently and have different capacities for tablet making. Let’s understand the difference between Simple and Rotary Compression Machines.
Single Punch Tablet Presses
A single-punch tablet Press is a tablet press that forms tablets through a single compaction process. Single Punch Tablet Presses, also known as single station tablet presses, are a traditional form of tablet manufacturing equipment. A single-punch tablet Press refers to a tablet press designed for tablet production in the pharmaceutical industry and related sectors. These machines operate on a simple principle where a single punch compresses the powder material into tablets. The process involves a series of steps, including powder filling, compression, and ejection.
