Optimal pellets cannot be produced using single machines or systems alone, but only on the basis of a seamlessly matched process chain – from cleaning and grinding to mixing, conditioning, pelleting, and cooling. And proper pellet cooling is one of the crucial process steps in the production of high-quality end products that has up to now not been adequately optimized.
Efficient cooling and continuous product discharge
Bühler CoolexTM is a breed apart by its visual appearance alone. Its innovative design based on the countercurrent principle and its conical product layer and octagonal geometry enable many important process steps to be optimized, ensuring a consistently high product quality of the pellets. With its specific air volume of merely 10 to 16 m3 per minute and metric ton.
But energy efficiency is only one aspect of CoolexTM that has a positive impact on feed producers’ margins. Thanks to the reliable reproducibility of the product quality, feed manufacturers can stretch the moisture content of their end product to the legally allowed limits and reduce their raw material consumption.
Another is the adjustability of the continuous product discharge rate, which ensures optimal throughputs and retention times. This cuts the capital investment and operating costs of downstream systems or allows higher throughput capacities to be achieved in a smaller space.
More hygiene and less costs
CoolexTM is the first pellet cooler to be provided with several service doors and up to four integrated inspection windows. This makes cleaning of the cooler very much easier and significantly reduces product deposits, greatly diminishing the contamination risk. But the smart design of this cooler offers even more benefits, for it needs much smaller fans This cuts energy consumption in comparison to other countercurrent cooler designs by as much as 10%. CoolexTM has a minimum number of wear parts and no hydraulic components at all. And cost-effective air cushions that can be exchanged in a mere 60 minutes not only minimizes downtimes, but also ensures dependable, low-maintenance operation.
