Vacuum drying: suitable for temperature-sensitive substances

Vacuum drying is characterized by fast drying times at low temperatures. We apply this contract drying method to materials that are sensitive to temperature or tend to cake. As the name implies, a vacuum dryer removes the pressure on drying compartment: it creates a vacuum. Together with gentle heat, the liquid in the material evaporates. We recondensate the liquids after having filtered the gas stream. The result is a gently and homogeneously dried product.

Your advantages of our contract vacuum drying:

• lower costs and free capacity through outsourcing
• low temperatures
• fast drying times
• for temperature-sensitive substances
• gentle process without quality reduction by heat
• homogenous drying results

We have vacuum paddle dryers and vacuum tumbler dryers with a volume of 50 to 12,000 liters for your drying process. With different blade arrangements and speeds (turbulent drying) or as tumbler dryers with enamel surfaces, we are able to carry out a variety of jobs with the right technology to save you money. Send us an inquiry.

Vacuum or spray drying: which technology is suitable for your material?

Whether vacuum or a spray dryer better suits your material for drying cannot be answered flat rate. Together with your process technology experts and product developers we clarify the question face to face. We are a very experienced service provider in the field of contract manufacturing and especially toll drying. With our knowledge and our facilities, we will certainly find the right method to fulfill your order to your satisfaction. All parts of our equipment with which your product comes in contact are made of stainless steel or enamel or corrosion proof alloys such as Hastelloy. The systems are heated with steam, water or thermal oil – for maximum quality and purity. We also advise you on our other services in chemical contract manufacturing.

Powerful spray drying for powder production

In addition to vacuum dryers, we also use different spray drying systems with an evaporation capacity of 40 to 450 liters per hour when drying your materials. Spray drying is used when solutions, suspensions and emulsions are to be converted to free-flowing powders. In principle, spray drying works by finely atomising the material to be dried and then vortexing it with hot air. You decide on the respective particle size of the finished powder. We meet your quality requirements through strict controls and compliance with legal requirements and guidelines. We always guarantee the highest and consistent quality in the drying process.

Your benefits of our toll spray drying:

• lower costs and less strain on your equipment
• high temperature range up to 400 ° C inlet temperature

Compacting: We convert your powder into low-dust, free-flowing granules

If you want to get a free-flowing and easy-to-dose product from your powder or fiber mixture, compacting or granulating is the most effective method – and ProChem is your partner who masters this process down to the last detail.

Over the past 20 years, ProChem has built a substantial portfolio of services as a professional contract manufacturer to serve our customers in the chemical, pharmaceutical and related industries. This includes the compacting of powder. We convert it into low-dust and free-flowing products, which can be processed more easily and safely.

Contract compacting: We compact so you can work dust-free

Statutory regulations on occupational safety and the risk of a dust explosions make working with powders with high fines fractions problematic. As a result, workplaces with high levels of dust have to fulfill special requirements. Meeting them is a costly affair – but failing to meet them quickly poses a threat to life and limb. Now you cannot or do not want to forego the use of powdery or dusty substances. Then you can either upgrade your own production sites according to the regulations for a lot of money or you can use our contract compacting services.

Write us an inquiry.

Dust explosion: Do not take any risks, let us compact your powder

Many of our customers entrust their lives and that of their employees to us by placing an order to compact their powder materials. The danger of a dust explosion is omnipresent and therefore by no means to be underestimated. Deterrent catastrophes have occurred in the past, especially in the pharmaceutical and chemical industries, as well as in plastics and wood processing. Dust that has been processed or produced during the production process cannot be exploded by a relatively small spark, with fatal consequences for the company and the workforce. Do not underestimate the threat of a dust explosion. Let us compact your powder and put it in a safe form.

Feel free to contact us.

We press your powder materials into shape for you

Compacting is really nothing but pressing. In our compacting plants, your material is compacted until it is compact in a form that you have previously defined. You can choose between a variety of pellet shapes. At the end of pressing you will basically get the same product as before, but now you can handle and work with it comfortably and safely as well as dispensing it more easily. No additives or foreign substances are added to your fabric – if you do not want to. It is compacted only between press rolls and converted by crushing and screening equipment to a granulate with any grain size and previously defined degree of compaction.

For a detailed explanation of compacting or any other of our services, please contact us directly.
