Your high-performance,multi-purpose batch dryerGentle and efficient drying are crucial requirements in modern productionplants for chemical or pharmaceutical products. Other prerequisites aremaximum flexibility, minimum product loss, contamination-free producthandling, and fully automated cleaning. The ANDRITZ Gouda helix dryerhas it all.From friable bulk goods to sticky pastes, our ANDRITZGouda helix dryer can handle many products. Thevariable speed drive of the helical mixer – a top-driven,central agitator – allows maximum flexibility andoptimizes the mixing process for different materials.One dryer for multiple products and multiple purposes.Thanks to its fully automated cleaning cycle, theANDRITZ Gouda helix dryer is perfectly suited tomulti-purpose production plants. The cleaning processtakes place between batches and guarantees contamination-free product handling. By heating the vessel wall– and optionally the mixer as well – the ANDRITZ Goudahelix dryer becomes a high-performance contact dryerfor thermal solid/liquid separation at low temperatures,known for its gentle yet efficient heat transfer. Thesteep vessel wall in combination with central productdischarge at the bottom provides fast, easy emptyingwith minimum product retention.MAIN APPLICATIONS Active Product Ingredients (APIs) Antibiotics Amino acids Fine chemicals Food Pharmaceutical intermediates Agrochemicals Dyes, pigments Precious metalsYOUR BENEFITS Gentle processing Optimum discharge of product Easy access for inspection High thermal transfer3
Improved product handlingThe ANDRITZ Gouda helix dryer is not only a flexible, multi-purpose batchdryer. It has many more advantages to offer you. Improved processing,high heat transfer rates, maximum product discharge, and fully automatedcleaning are just some of the latest generation’s design benefits.GENTLE PROCESSINGConstant movement and lifting of the product alongthe heated vessel wall and continuous backflow intothe center of the vessel ensure efficient and, at thesame time, gentle mixing. Combined with small clearances between the helical blade and the vessel wall,this results in high heat transfer to the product whilepreventing agglomerates from forming or depositsfrom building up. The shear forces arising are minimalwith this kind of mixing as the circumferential speed ofthe helical mixer is low. The variable speed drive allowsmaximum flexibility and optimizes the mixing processfor different materials.VACUUM CONTACT AND FINAL DRYINGThe design of the ANDRITZ Gouda helix dryer has allthe advantages of vacuum contact drying, such as lowthermal load in the product, high thermal efficiency,safe processing of explosive substances, and simplesolvent recovery. When drying down to the ppm (partsper million) range, a carrier gas can be introducedoptionally through a special deodorizing nozzle directlyabove the product discharge.MAXIMUM PRODUCT DISCHARGEA central outlet in the lowest section in combinationwith a steep vessel wall ensures almost completeproduct discharge by gravity while the mixer is running.In addition, the specially shaped helical blade isdesigned for minimum product retention throughoutthe agitator.NO PRODUCT CONTAMINATIONThe shaft seal (lip sealing or mechanical sealing) islocated outside the product area, preventing anycross-contamination or extreme wear. The drive andbearing assemblies are completely separated from theprocess area. This allows easy maintenance withouthaving to enter the vessel. If required, large dryers canbe accessed for inspection and maintenance via widemanholes in the cover.FULLY AUTOMATIC CIPCIP (cleaning-in-place), allows fully automatic cleaning without opening the vessel. Spray devices in thevessel cover and at the internal fixtures ensure that allinternal surfaces are cleaned properly with cleaningfluid. The cleaning process takes place betweenbatches, which makes the ANDRITZ Gouda helix dryerperfectly suited for your multi-purpose productionchains.4Sight glass for product visual

Lower operating costs andimproved product qualityThe patented vessel design and top-driven helical mixer allow you toincrease the throughput, intensify the process and reduce your energycosts. Some of the unique selling points of the ANDRITZ Gouda helixdryer are described here below.ROBUST DESIGNCompared to the tradional design, the overall height ofthe ANDRITZ Gouda helix dryer is reduced significantly( 25%) because of the patented, conical-conical vesselshape. The special shape results in a shorter mixershaft, providing a more robust design, which is helpfulwhen you need to mix sticky products. Also, it simplifiesinstallation in areas with limited space.SAMPLINGA piston valve is located in the lower area of the vesselso that product samples can be taken during thedrying process. The residual moisture can be analyzedin the customer’s lab.MIXING OF PASTY PRODUCTSProcessing of pasty products is possible thanks to theinstallation of a fast-rotating chopper in the lowerarea of the vessel. It also prevents lump formationduring drying.ENL ARGED HE AT TRANSFER AREAOptionally, the upper helix blade and the shaft canalso be heated to enlarge the overall heat transferarea and prevent condensation on machine partsabove the product filling level.OPTIMUM BLENDINGThe conical-conical vessel shape eliminates areaswith poor blending characteristics in the lower part6of the vessel. In addition, the special steep, verticallyinclined agitator shape allows you to process productswith poor rheological properties. Combined with a90 angle towards the vessel, the vertical incline ofthe helix blade ensures complete emptying of themachine, even for products with strong bridge-buildingcharacteristics.WIDE PRODUCT RANGEANDRITZ Gouda helix dryers are mainly operatedas vacuum contact dryers, but sometimes also asreactors. The product range contains dryers of all sizesas well as smaller mobile units for your laboratory orpilot operations. With this wide product range, we accommodate individual demands and offer tailor-madesolutions.COMPLETE SOLUTIONA variety of peripherals are available for optimumoperation of your ANDRITZ Gouda helix dryer, and theymeet the most demanding requirements: integrated ortop-mounted dust filter, isolation valves without deadspots for filling, discharge, and sampling, CIP sprayingdevices, purge gas systems, vacuum skids, heating/cooling units, and solids handling systems, all with amodular design. In combination with our Krauss-Maffeipeeler centrifuges HZ, complete solution packages canbe provided for mechanical and thermal separationtasks, especially in the chemical and pharmaceuticalindustries.ANDRITZ Gouda helix dryerfor lower operating costs andimproved product quality

More flexibility with themobile ANDRITZ Goudahelix dryerProcessing product batches in series or transferring products from oneprocess step to the next may lead to product loss or contamination.Filling, transport and product discharge with one single mobile dryer.Our mobile ANDRITZ Gouda helix dryer provides theanswer to these operating issues. The most importantbenefit of using a smaller, mobile version of theANDRITZ Gouda helix dryer is the flexible processset-up. The mobile design is available for fork-lifttransport or for manual transportation on wheels. Ifrequired by your plant layout (i.e. for laboratory orpilot-plant operation), the dryer can be used as atransport vessel. As such, filling, drying, discharging,and cleaning can be performed at different locations.In addition, the use of special containment dockingsystems prevents any contamination of the product orthe environment. A typical process set-up is as follows:The mobile ANDRITZ Gouda helix dryer is connecteddirectly to the solids discharge of a peeler centrifuge.After charging the dryer, the closed vessel is movedon wheels or via fork-lift truck from the centrifuge to acentral drying station. Here, the dryer is docked to thedrive unit, the vacuum skid, and the heating/coolingunit.The whole process is safe, sterile and extremelyflexible. Mobile dryers are available up to a usefulvolume of 150 liters. As an option, we supply the coverof mobile units with a hinge that allows the lid to openfully. It enables full inspection of all vessel parts wettedby the product.YOUR BENEFITS Flexible operation Contamination-free product handling Reduced product losses as fewer process stepsare needed Simple and full inspection of all vessel partsMobile ANDRITZ Gouda helix dryerfor flexible operation8
