Most tray dryers used in the pharmaceutical industry comprise a heated cabinet in which a rack of trays is located. They are frequently used for the drying of granulated powder. Heat can be provided by burning a fuel, e.g. natural gas or, more usually, by one or more electric elements located within the cabinet, together with a blower to circulate the air.
Tray dryers are devices used to dry wet products of chemicals, powders and crude drugs. The simplest way to explain a tray dryer is a cabinet that has a heater at the bottom or a laboratory oven. The oven has little to no value because control is non-existent for humidity and heat transferred.
Tablets are defined as solid form of drug dosages where each unit is made up of one or more medicaments. Administered orally, the tablets are made up of powdered drugs with excipients that are compressed into its solid form.
Description: Double Impression includes punches that embed monograms or images on tablets.
Cause: During the impression stage, each tablet undergoes imprinting. In the said stage, engraving machines imprint on the tablet; with the double imprinting, the lower punch might be uncontrolled and drops freely the short distance causing a new imprint on the tablet producing the double imprint on the tablet.
There are two principal methods of coating tablet: sugar coating and film coating. Both have advantages and disadvantages, and the following table provides a comparison between the two methods. The choice of which method is appropriate depends to an extent on how the tablets have been produced, the composition of the tablet and the intended market.
The dry granulation process is a process whereby granules are formed without the aid of any liquid solution, as the ingredient to be granulated is moisture- or heat-sensitive. To form these granules, it is important to use compacting and to densify the powder. A slugging tool or a roller compactor tablet press machine is used to conduct the dry granulation process.
Validation is establishing documented evidence which provides a high degree of assurances that a specific process or equipment will consistently produce a product or result meeting its predetermined specifications and quality attributes.This article focuses on the process of dry mixing of powders, as one of the steps in producing tablets.Validation can therefore be applied to the dry mixing process itself, as well as the overall manufacture of tablets.
In sterile pharmaceutical preparations such as required for injectable dosage forms, the drugs are often supplied in glass vials. These should be cleaned before filling, and although automatic vial washing machines may be used to clean vials, it is important to have the cleaning process validated. The efficiency of the washing machine and process is verified by performing several tests, as follows.
The manufacturing of a tablet includes compressing a drug with several excipients. Mere compaction of a dry powder between two punches yields a tablet that easily crumbles.

In wet granulation, powders are bound together using adhesives rather than compacting motion. As more liquid is added to the mix, bridges form between the particles, which increase the tensile strength of bonds.
The process of wet granulation includes the massing of mix dry powders with granulating fluid. The fluid contains solvent, which can easily be removed when dried. The fluid should be non-toxic and may include water, isopropanol, ethanol and methylene; they can be used alone or combined with other solvents.
Capsules are popular and commonly used in the pharmaceutical industry, not only is it easy to manufacturer but it do not need any complex formulation unlike other drug containers.
The oral liquids are homogenous liquid preparations, which contain an emulsion, solution and suspension of one or more active ingredients that are suitable as liquid base. These preparations are administered either as is or after dilution. The preparations contain other substances such as emulsifying, dispersing, solubilizing, stabilizing, suspending, wetting, thickening agents and antimicrobial properties for preservation.
What Is The Right Compression Tooling Equipment To Use
Tablet manufacturers need to choose the right compression tools to ensure that high quality tablets are produced. Before equipment is purchased therefore, it is important to establish good communication between manufacturer and equipment supplier.
A single station tablet press is a simple mechanical machine that can be used to compress powder into tablets that are uniform in size, shape and weight. The machine is used for low-volume production of tablets for a wide range of applications from cosmetics and pharmaceuticals to cleaning products.
When it comes to taking supplements and multivitamins, we all know how horrible it can be. Often these comes in tablet sizes that are hard to swallow and sometimes leave a bitter taste thereafter. That said, thanks to recent improvements in the industry, one is no longer confined to tablet or capsule supplements as nowadays, gelatin supplements make it easier for people to take these supplements. To better understand gelatin supplements, below is a brief about the product and what benefits one can get as well as the different varieties available in the market today.
Even the simplest form of pharmaceutical manufacturing process can involve a range of process steps before the product is packaged and shipped to the consumer.These may include:
This is a frequently asked question on the TDP range. This range of single station pill press includes the TDP 1.5, TDP 5 and TDP 6s. The machines are very similar and the main distinction between them is the pressure that is exerted during tablet making.
In the pharmaceutical manufacturing process, it is important that blend uniformity be achieved. If there is poor uniformity, the product can be rejected based on weight or punch pressure causing loss of revenue to the your business. In this article we talk about how to overcome this problem.
