Tablet Press Operating Guide

The tablet press is a mechanical device that can press powder or granules into tablets. It is widely used in the pharmaceutical, food, chemical and other industries. It has strong tableting ability and can make the pressed products have similar shapes, weights and hardness. It is an indispensable key equipment for making tablets, health tablets, candies, etc. Let's talk about the purpose, performance, operation method of the tablet press in detail, and what a rotary tablet press is.

The purpose of the tablet press

The tablet press is mainly used to press a certain weight of powder or granules into tablets to meet production needs.

Mainly used in these places:

Pharmaceutical industry:

Used to press tablets, such as single-layer, double-layer or multi-layer tablets. Commonly used in the production of prescription drugs, over-the-counter drugs, and vitamin tablets.

Food industry:

Used to make oral candies, chewable tablets, nutritional supplements, such as calcium tablets, protein tablets, etc.

Chemical industry:

Used to press some industrial chemicals or experimental tablets.

Other industries:

Small battery cells in electronic products are also made by tablet presses.

Performance and efficiency of tablet press

The performance of tablet press has these characteristics:

High precision:

With very precise molds, the force can be well controlled during tableting, so that the weight and hardness of each tablet of medicine or food are consistent.

High efficiency:

Especially the rotary tablet press, which is very fast and can press thousands or even tens of thousands of tablets per minute, is particularly suitable for mass production.

Versatility:

It can make tablets of different shapes, such as round, oval, and some special shapes, and even multi-layer tablets.

Consistency and stability:

The size, weight and density of the tablets can be very uniform every time the tablet is pressed.

Easy to operate:

There is an intelligent control system, just like a PLC touch screen, which can easily adjust parameters and find faults.

The factors affecting tableting efficiency are:

Tableting speed: The rotary tablet press is much faster and more efficient than the single punch tablet press.

Number of molds: The more molds, the more tablets can be pressed in one cycle.

Powder fluidity: If the material is uniform and has good fluidity, the filling quality will be high.

Pressure regulation: When tableting, only when the pressure is appropriate can the hardness and stability of the tablet be guaranteed.

How to tablet

There are basically several steps for tableting:

Material preparation:

The powder or granular material must be made into granules to make it flowable. The powder must be dry and cannot clump.

Mold installation:

The mold must be installed according to the required tablet shape and size, and the punch and middle mold must be installed.

Filling:

The material is evenly poured into the mold with a feeding device.

Tablet operation:

Turn on the tablet press, and the punch forces the material into the required shape. When tableting, the pressure and thickness must also be adjusted to achieve the required tablet specifications and hardness.

Tablet discharge:

The pressed tablets will come out of the discharge port by themselves and can enter the next process, such as coating, packaging, etc.

Cleaning and maintenance:

After production, the mold and equipment must be cleaned, otherwise the residual material will affect the next production.

Precautions:

Ensure that the material is uniform, and do not let the particles be of different sizes or have deviations in weight.

Regularly check whether the mold and punch are worn to ensure product consistency.

Rotary tablet press

The rotary tablet press is a multi-station, highly efficient device that is very suitable for large-scale industrial production.

Its working principle is as follows:

The mold and punch of the rotary tablet press are installed on a rotating turntable. The turntable rotates at a certain speed. The material enters the hole of the mold from the feed port. When the turntable rotates, the upper and lower punches apply pressure to the material to press out the tablets.

It has the following characteristics:

High-speed production:

It can produce thousands to tens of thousands of tablets per minute, and large-scale production depends on it.

Multi-station design:

The number of molds on the turntable determines how many tablets can be produced in one cycle.

Flexible adjustment:

Tablets of different shapes and sizes can be quickly replaced to meet various needs.

Strong stability:

The mechanical structure is very strong, very stable during tableting, and can work for a long time.

Intelligent control:

With automatic detection and fault alarm system

As mentioned above, tablet press is the most critical equipment in tablet production. Choosing a suitable tablet press is the first step for enterprises to move towards efficient production. Choosing an efficient, safe and high-quality tablet press can improve your production methods and efficiency.
