Highly productive

Despite the attractive packaging, you cannot see everything that is in roha products. This concerns not only the curative effect, but also the numerous steps of production and processing: starting with the storage and testing of raw materials, to making capsules, tablets and dragees, to packaging, analysis, quality control, and through to logistics and shipping. All of these steps are united under one roof at roha.

First and foremost: basic production

Keeping it clean – herb processing

Senna bales

Our warehouses annually receive an average of 800 tonnes of crude drugs. At the end of production, fine cuts are produced for herbal teas or for extraction.

Production begins with an intensive cleaning of mineral and magnetic contaminations by metal separator and air separation plants, followed by cutting and mechanical sieving. The fractions of material can then be packaged and stored temporarily for extraction.

Filter fresh – extraction / spray drying

Boiler with Senna dilution

An intensive extraction process, percolation, removes the desired ingredients from the plants – gently, with water and not with alcohol. A centrifuge then cleans the result (percolate) of suspended solids. 

Long process

The next step: the concentration of the existing weak extract in an evaporator system. The concentrate then undergoes the necessary sterilisation treatment and is spray dried at the end using ultrafast heating. Here the liquid active-extract is sprayed at high-pressure under direct current with warm air into a spray-drying tower and dried before being homogenized in the mixer.


More than a formality – pharmaceutical shaping

Valuable content, perfect shape: in the process of mixing, tableting and tablet coating, powders, granules, tablets, coated tablets, capsules and dragees are produced.

Precision work – weighing, mixing, granulating

Powder mixture

The starting materials are accurately weighed in strict compliance with the particular recipe and then mixed for a precisely defined time. In the event that further processing is required, granulation follows, from which granulate is produced from the powder.

Under high pressure – tableting

…requires the addition of auxiliary materials to make tablets or cores for dragee production from the granulated powder mixture. The tablet presses condense the mixture under high pressure, forming compacts, which are subsequently dedusted and checked for impurities.

Tablet cores

Brilliant results – dragee manufacturing

Coated tablets

In a multistage production process, a casing of auxiliary materials for finishing the compacts is produced. The dragee core initially has a protective layer so that no water can penetrate during processing. After an additional coating of the insulated cores with a mixture of sugar and inorganic auxiliary materials, the process is completed with the polishing and sorting of dragees.

Capsule production

roha capsule products consist of empty gelatin or empty cellulose capsules. In the piercing lifting method, each amount necessary is taken from a bed of the active ingredient powder, lightly compressed and filled into the empty capsules. This method is particularly well suited to poorly flowing powder. Finally, the finished capsules are dedusted with the so-called capsule polisher.

Under constant supervision

Regular in-process checking throughout the entire production cycle ensures consistently high quality. This includes testing to ensure both the delivery of standardized quantities and the quality of the enteric coatings necessary for the active ingredients to pass through the stomach intact, monitoring dissolution times to ensure that active ingredients are released rapidly, checking physical parameters such as packed weight, and dosage-form dimensions, and examining packaging integrity to ensure that the licensed medicines reach the patient both undamaged and accompanied by the necessary statutory information material.

Packaging: well-received.

Every kind of packaging: roha has packaging lines for dosage forms of herbal teas and bulk goods in cans, instant tea in glasses, tablets, capsules and dragees in blister packs as well as sugar-coated tablets in plastic cans.

Packaging of herbal teas and bulk materials in composite cans

The powder or tea mixture is transferred into chambers of a multi-head weighing system. Computers determine the target weight and control the filling of the chamber contents into cans.
They are given a base and a secure closure as well as batch number and expiry date and a label. They then automatically go into the shipping box.

Packaging of instant tee in glasses

After automatic de-palletising and cleaning, the glasses are filled, glue is applied to the opening, and then they are sealed with a lid. The aluminum foil contained in the lid ensures a tight tamper-evident closure.
After labelling, the jars are packed into shipping cartons and palletised automatically.

Packaging in blister packs

Here dragees, capsules or tablets are automatically inserted into individually manufactured, product-specific wells of plastic film, subjected to a filling control and welded with aluminum foil. The punched blisters then land up together with the package insert leaflet in their carton. Finally, the finished packs pass through a checkweigher to the bundling machine for packaging into shipping cartons.

Packaging in plastic cans

First of all, plastic cans are labelled. At the filling station, the tablets or dragees are counted and funneld in and the fill amount checked. Each then receives a plug as a closure and then a package insert leaflet and carton in the cartoner mashine. The finished packs are weighed, bundled and packed into shipping cartons.
