HEAT TREATMENT SYSTEM

STATE OF THE ART TECHNOLOGY FOR THE FEED INDUSTRY

IntroductionMore and more antibiotics arebanned from animal feed, due toresistant bacteria. The ForbergHeat Treatment System is thenthe answer for the high require-ments of the feed industry.Intelligent heat treatment combi-nes efficiency, quality, and highcapacity with the possibility toadd heat sensitive additives atthe latest stage of the process.Cross contamination is reducedto a minimum.

The ProcessIn the first step of the process the condi-tioner/mixer is charged with the feed,which has to be treated. The feeding cantake place out of a single bin or differentcomponents can be mixed with theForberg high speed mixing process.Then steam is injected into the mixer toheat up the product to the desired tem-perature. Now the temperature is main-tained over a certain period of time to killsalmonella and certain kinds of bacteria.In this stage of the process liquids,which are not initially hygienic like molas-ses for example, can be treated as well.After the heat treatment the mixer dis-charges directly into a dryer/cooler.The mixer and the chutes are heated tomaintain a temperature over the dewpoint at all surfaces. As soon as thedryer is charged the conditioner can al-ready produce the next batch. In the dryer, warm air is first introducedto extract some moisture from the pro-duct. In the second step ambient air isblown in to reduce the product tempera-ture further. After the product hasreached the desired temperature andmoisture content, additives such as vita-mins, enzymes, flavours, pharmaceuti-cals, etc., which are sensitive to heat canbe added. The additives can be appliedin powder or liquid form. They will be

mixed to perfection with low CV values.The product is now ready to be stored,packed or transported. There is nosegregation that has been observed likein many other processes because tran-sport of the final mixture is very short. The air of the process goes through a fil-ter unit before being released clean tothe environment, or alternatively it is cir-culated to a water-cooled air cooler andused again in a closed loop system.After drying and cooling in a Forbergdryer/cooler/mixer the process ends. Themixture is now ready for packaging, bulkloading or intermediate storage.

✔ HIGH THERMAL EFFICIENCYof the whole process. As an optionForberg offers a closed loop systemto increase the efficiency evenmore.

✔ MICRO AGGLOMERATIONThe injection of steam leads tomicro agglomeration of the treatedproduct, which reduces the risk ofsegregation and minimises dust.

✔ HIGHEST MIXING HOMOGENEITYThe mixing quality (homogeneity) ofthe end product is maintainedthroughout the process.

✔ ADJUSTABLE MOISTURE CONTENTThe moisture content can be controlled very precisely. The desired degree is adjustable.

✔ NO LOCAL OVERHEATINGDue to the unique Forberg condi-tioner/mixer the product is heatedvery uniformly with less than 0,5°Ctemperature difference throughoutthe batch. There is no local overheating.

✔ MINIMISED CROSSCONTAMINATIONCross contamination is minimiseddue to the batch process and veryshort transport of material.

✔ CONTINUOUS OUTPUT/HIGH CAPACITYHigh capacity due to quick cycles.Multiple batching leads to continu-ous output.

✔ GOOD FOR HEAT SENSITIVEADDITIVESHeat sensitive additives such asvitamins, enzymes, pharmaceuti-cals, medicines, colours, flavours,etc. can be added in the lateststage of the process and will bemixed to perfection. Additives maybe powders or liquids.

✔ FLEXIBLE RECIPE CHANGEHighest flexibility of the production ifthe recipes are changing. Quick andeasy changing of formulas.

✔ EASY TO CLEANWith automatic wash as an optionthe cleaning is easy. Access to themachine is optimized, maintenanceis very comfortable.

✔ ENVIRONMENTAL FRIENDLYEnvironmental friendly due to stateof the art filter technology.

✔ FOR NEW AND OLD PLANTSAdaptable to many existing sys-tems. Old and new feed mills canbe upgraded with the ForbergTechnology.

✔ COMPACT LAYOUTVery compact design allows theintegration of the system in existingfactories. The overall height of newplants is significantly lower thanother systems; therefore the overallbuilding costs are greatly reduced.Very often this is also a benefit whileasking for building permissions.

✔ PROVEN COMPONENTSCombination of high quality Forbergcomponents, result in a very reliablesystem.

✔ FORBERG SERVICESForberg provides engineering withthe possibility to carry out the civilworks manufacture the steel struc-tures and silos locally. This lowers the overall investmentcosts for the benefit of the custo-mer.
