Mixing Dryer and Conical Vacuum Dryer through industrial drying, many industries such as pharmaceutical industries, chemicals, food processing industries and agricultural products have found it essential. The Mixing Dryer and the Conical Vacuum Dryer are two very effective drying equipment provided by INCMachine that dries and mixes simultaneously in a single system. Although they are both aimed at shortening processing time and the quality of the products they are processed, their principles of work, construction, and implementation are also very dissimilar.

This elaborate comparison will ensure that an industry person knows which machine suits him better based on his performance, energy efficiency, the compatibility of the products he has and the operating conditions.

How does the Mixing Dryer Work?

INCMachine Mixing Dryer is a horizontal machine that is fitted with plough type agitators that mix materials as well as drying them. Its mode of operation is that, it forms a fluidized layer within the chamber where a product is lifted, dispersed and evenly introduced to the hot surface. This enhances quicker drying of the increasing contact and transfer of heat.

This dryer is of regulated temperature and vacuum or pressure. High-speed choppers may also be added to it to crushed lumps and provide uniform consistency. It is a multifunctional machine that can easily be equipped with a spray system enabling granulation, suitable machine to process materials that need to be mixed quite intensively and their drying controlled precisely.

The major Advantages of the Mixing Dryer

• Rapid drying because of fluid mixing
• Jacketed design thermal efficiency
• High thermal efficiency
• Liquid and gases not appropriate Suitable to powder, granules, slurry, and pastes
• Chopper and spray granulating systems
• It is a batch or continuous operation design
• Cleanable easily, suited to use in GMPs

Background of Conical Vacuum Dryer

The Conical Vacuum Dryer can be characterized by a vertical conical vessel and the slow speed screw that delicately dislodges the product at the bottom of the cone and lets it fall by gravity. The constant movement mixes very well and handles the materials delicately, therefore, this is perfect where materials are sensitive to heat and are delicate.

Heating is done either by the use of the double jacket or within the screw itself. It is a vacuum system and thus enables low temperature drying, ideal with pharmaceuticals and active ingredients as well as sensitive chemicals.

Values of the Conical Vacuum Dryer

• Sensitive products mixing and low shear Gentle mixing
• Excellent vacuum efficiency for low-temperature drying
• Slow orbiting screws of uniform drying
• Complete product discharge owing to shape of a cone
• Integrated solvent recovery, condenser and filters
• Adherence to Hygienic and GMP requirements

Comparison of Drying Technology

Mixing Principle

Mixing Dryer With plough-type agitators: the Mixing Dryer is intensely mixed in plough-type agitators and may be fitted with high-shear choppers. The materials are continuously stirred up to form fluidized bed that guarantees uniform exposure to heat.

Conical Vacuum Dryer has a slow moving screw, which rotates on the side of the cone and folds the substance in. This will guaranty a smooth but thorough mixing which is preferable over fragile materials that cannot be broken into pieces during drying.

Drying Method

The Mixing Dryer presents the combination of a mechanical agitation and warmed jackets and terms of vacuum. It is utilized in forced convection and conduction to eliminate wetness quickly.

Conical Vacuum Dryer is based on the conduction heating used under vacuum. It gives a slow and constant drying rate with little product degradation, and it is appropriate to solvent recovery and moisture-sensitive products.

Industry suitability and Applications

• Dryer Applications Mixing
• Powder coating and agglomeration
• Additives on food and coarse grains
• Medical compound profane intermediates
• Agrochemical mixing and drying
• Thermal resistant polymeric compounds
• The catalysts and metal powders
• Applications of Conical Vacuum Dryer
• Active pharmaceutical ingredients
• Herbal extract and biologicals
• Fine chemicals and reactive powder
• Solvent based formulations
• Cake filter cake and slurry
• Crystallization drying processes

Energy Consumption and Efficiency

The Mixing Dryer is highly energy efficient since the three processes mixing, drying and granulating are performed in a single vessel. It shortens the time and costs of operation.

The Conical Vacuum Dryer, although slower, is highly energy-efficient for low-temperature drying processes. The boiling points are minimized by the vacuum and the solvent can be removed without harm caused by heat.

Whiting and Sanitation Details

Both the dryers are easy to clean and possess high standards of hygiene. The Mixing Dryer is in a horizontal configuration and it is easy to access it and clean it manually or clean in place (CIP).

The Conical Vacuum Dryer has been developed such that polished conical vessel and cantilevered screw is designed without bottom bearings that increase risks of contamination. It cannot do this with CIP and SIP choices of pharmaceutical-grade applications.

Discharge and Product Recovery

The Mixing Dryer can hold more material (mostly in viscous or sticky products) because it is horizontal. Nevertheless, it is effective in the case of bulk materials which do not need full emptying.

The Conical Vacuum Dryer will guarantee close to 100 percent discharge due to its vertical-conical design and the downward stream of flow. This will be an advantage in high cost or sensitive products where there should be minimum product loss.

What is the Best Dryer?

Buy the Mixing Dryer:

• Your process demands fast drying and high-shear mixing
• You need granulation in the same vessel
• The materials used by you are not flimsy and heat sensitive
• You use continuous or semi-continuous production preferably
• Frequency of cleaning/ changeover is moderate
• Select the cone shape Vacuum Dryer when:
• Your product is vulnerable to heat or is delicate
• You need very accurate vacuum control and solvent recovery
• The vitality of the batch and low contamination is necessary
• The industry you are in requires GMP compliance
• You deal with high price or pharmaceutical-level goods

Conclusion

Each of these two different types of industrial drying processes, the Mixing Dryer and the Conical Vacuum Dryer have different types of distinct advantages. The Mixing Dryer can be used in drying quickly, solvent-proof materials, and combining granulation. On the other hand, the Conical Vacuum Dryer provides gentle mixing and low-temperature drying, making it ideal for sensitive and high-value products.

Depending on the nature of your product properties, production demands and regulatory requirements you can choose the best drying technology. INCMachine offers any kind of solutions be it the standard or custom solutions to accommodate the needs of the current industrial processing.
