ALLGAIER PROCESS TECHNOLOGY

DRYING OF SOLUTIONS AND SUSPENSIONS CONTACT DISC DRYER - DRYING OF LIQUIDS CONTAINING SOLIDS The CDry is used for efficient treatment of liquid products containing solids, like suspensions or solutions to be processed into dry goods. A liquid containing the material to be recovered is fed onto a heated rotating disc array where the liquid evaporates leaving behind solid material that is mechanically scraped off. A main benefit of the CDry is the arrangement of a large heat transfer area on a small footprint. Compared to convective drying technologies, a contact dryer such as the CDry has...

HOW THE ALLGAIER CDry WORKS Liquid is pumped from a product buffer tank into the circulation tank. The suspension is conveyed by a circulation pump to the individual feed pipes next to the heated, rotating discs. The feedpipes transfer the liquid onto the discs and excess liquid is returned to the circulation tank. The liquid on the heated disc evaporates during one rotation. The degree of product dryness can be controlled by the rotation speed and the heating steam pressure of the discs. The dried or concentrated product is scraped off the discs by blades and the resulting dry product is...

ROBUST TECHNOLOGY AND COMPACT DESIGN Because of their special, slim design, the disc assembly enables very good heat transfer resulting in a highly efficient drying process. Because high quality stainless steel is used in key processing areas of the Allgaier CDry, it is very robust and durable. The operational status of the CDry is visuable at all time on a large touch screen panel, easily accessed on the machine. The multi-colored light, located on the top of the machine housing, shows the machine status and is easy visibile by the operator. Various levels for “standard” operational...

OPTIMAL ACCESSIBILITY FOR MAINTENANCE The Allgaier CDry is designed for operational visibility and ease of maintenance. The hood located on the front of the machine contains a large pane of safety glass looking into the disc package to observe the system during operation. For illumination of the process area, a light is directly located above the drying discs. The hood lifts-up and out of the way for convenient access to the processing area for cleaning and maintenance. Large doors also pivot out and away from the technical chambers for maintenance and service. ALLGAIER PROCESS TECHNOLOGY

MODEL OVERVIEW MODEL OVERVIEW THE RIGHT SIZE FOR YOUR APPLICATION There are currently three (3) models in the Allgaier CDry family: The Allgaier CDry 501 lab is primarily used for drying small quantities of material or in a lab for developing new applications. The Allgaier CDry food is perfect for the highest demands of the food and animal feed industries. The Allgaier CDry, the original Allgaier disc dryer, continues to serve the needs of the chemical industry, wastewater technology, pigment and high-value suspension industries. No matter which size CDry you choose, we will meet the high...

With its range of models, sizes and possible configurations, the Allgaier CDry can serve a wide variety of industries, applications and capacities. The CDry 501 lab, with a single drying disc and small surface area of 0.4 m², can be used to produce relatively small quantities of dried material. The 900 Model series of dryers have discs with a diameter of 900 mm for medium capacity needs. This model can also be supplied as a CDry food version, designed to meet the strict design and material requirements of the food industry. Along with the 900 Model series, the 1300 Model series with larger...

CDry The size and materials used for the discs can be adapted to specific customer needs, including disc surface treatments regarding the issue of abrasion and corrosion. The Allgaier CDry was the recipient of the ACHEMA Innovation Award in 2020. ALLGAIER PROCESS TECHNOLOGY

CDry food FIT FOR FOOD The CDry food is based on the standard CDry model. However, the design of the process chamber and the components used in the CDry food family were developed in strict compliance with the latest EHEDG and FDA guidelines, making the Allgaier CDry food the contact dryer for milk/ whey products, high-quality food/feed supplements or any food-grade liquid requiring production of solid product. The highest product quality, robust system design, flexibility and user-friendly operation is why the Allgaier CDry food was awarded the International FoodTec Award of the DLG....

EQUIPMENT AND OPTIONS • Hygienic machine design • Process chamber design according to EHEDG guidelines • Easy cleaning of components in contact with the product • CIP System with integrated cleaning nozzles available for the process chamber as an option. • Optimized front window with sealing function for cleaning operation Heat exchange surface available from 2-12 m² in size • “Captive” surface treatment of the disc assembly to prevent surface coating flaking. • Fast and flexible adjustment of process parameters • Production of unique product variants due to contact drying possible OVERVIEW...

LABORATORY DRYER 501 The CDry 501 lab is based on the larger siblings in the CDry family, manufactured with the same robust design and high-quality materials. The compact dimensions make this CDry perfect for test labs, production simulations and small batch drying applications. The fully integrated steam/condensate components are located in the dryer housing itself. A single 0.4m² drying disc, simple installation, semi-autonomous control system via the integrated touch panel completes the package. Different pump options may be selected for circulating various types of liquid, and product...
