Head-turning results from rotary jet
heads
Process equipment and tanks used in ethanol production need regular cleaning to prevent contamination during the fermentation process: efficiency is improved with rotary spray heads
Effective cleaning of the fermenters after each production batch is therefore essential Conventionally, it's a duty that spray balls have been used for, either with or without biocides

Diffusion bonded heat exchanger has process debut
The AlfaNova 400, a new 100% stainless steel diffusion bonded plate heat exchanger enhanced specifically for process duties in hostile heating, cooling, evaporating and condensing conditions
Now, many processors are discovering that they obtain a more effective clean in greatly reduced cycle times by replacing their spray balls with rotary spray heads.
Spray balls simply don't provide the impact or coverage needed to get the job done thoroughly.
So, cleaning the fermenter vessel internal surfaces to the required standard either takes a long time or doesn't get done at all.

AlfaCond condenser for medium throughput duties
AlfaCond 400 is ideal for duties such as a condensing in evaporation and crystallisation or distillation systems, or as a turbine condenser in smaller co-generation plants
By contrast, Alfa Laval rotary jet heads carry out this and other essential tank cleaning duties rapidly, efficiently and automatically.
This specialist equipment is designed to provide 360degree indexed impact cleaning that has been pre-defined using sophisticated computer software over a preset period of time.
Such rapid, fully automated cleaning virtually eliminates downtime and other production disruptions necessitated by frequent tank cleaning.
In an age when water conservation is becoming a necessity, rotary jet heads also drastically reduce the quantities of water and biocide used in the cleaning operation.
More efficient cleaning of the fermenters also increases fermentation performance and saves money on antibiotics.
Main benefits for ethanol producers include:.
* Rapid cleaning, less downtime.
* Reduced biocide consumption.
* Reduced water consumption.
* Less use of antibiotics.
* Reduced manpower requirements.
* Reduced environmental impact.
Alfa Laval technicians generate detailed proposals indicating the ideal location of the machine needed to obtain optimum performance plus the piping and pressure/flow requirements, based on:.
* individual tank dimensions.
* key process parameters.
* cleaning intervals required.
Carried out using the Alfa laval unique TRAX software programme, this proposal also contains an analysis of cleaning shadows and produces customised cleaning patterns for each individual vessel.
Extensive experience in this field means that Alfa Laval is able to suggest the best possible operating procedures for this kind of tank cleaning equipment.
Before installing a new tank cleaning system, we will also provide customers with a trial machine to enable them to carry out real-time tests on their own site and compare the benefits and savings available compared with their existing tank cleaning equipment.
There are more than 100 UK companies currently using rotary jet heads for precise tank cleaning in industries as diverse as food, dairy and brewery to paperboard production.
