70 71 ARTICLE ARTICLE MILLER / JUNE 2020 MILLER / JUNE 2020 DETAILS OF THE INDIVIDUAL MACHINES Sieving with the Vitaris separator MTRD One coarse and two sand sieve decks divide the grain from coarse and fine impurities. The grain is fed through an adjustable distribution device in the inlet, spreading the product evenly across the top coarse screen sieve. Sand and seeds are intensively sifted from the grain by the fol- lowing double sand sieve decks. Overs are disc- harged through the machine fra- me saving space and reducing assembly costs. The separator achieves a high throughput of up to 24 tons per hour in the clea- ning process and up to 50 tons per hour for pre-cleaning at the grain intake in silos. Optionally, an air-recycling unit can be connected upstream or an aspiration channel downstream. OVERVIEW OF MAIN BENEFITS High in sanitation Stainless steel sieves, FDA-approved plastic parts and the omission of nails, plush and felt allow high sanitary standards. In addition, the closed design of the machine prevents any foreign parts from falling into the product. High in selectivity Double sand sieve decks provide a larger sieve surface. Three sieve decks, allow for higher selectivity. Low in maintenance costs The sieves can be easily tensioned and loosened. The perforated sheets on the sieve frame are fixed without the help of nails or screws. Thanks to a clever quick-clamping system the entire sieve deck can be changed in less than five minutes allowing for maxi- mum uptime. Configurations Like all machines in the Vitaris modular system, the Vi- taris separator MTRD can be combined with other units from the range, such as the Vitaris combistoner MTCH, to perform as a combi-cleaning system. Tailored to suit your requirements it can be flexibly combined with the air-recycling aspirator MVST and an air-recycling aspira- tion channel MVSS or both. Separating impurities with the Vitaris combistoner MTCH Re-using most of the cleaned process air, the Vitaris combistoner MTCH efficiently separates mixed and hi- gh-density products and impurities with specific weight such as stones and glass. Thanks to the integrated recir- culating air separators the machine requires little fresh air thus saving energy. OVERVIEW OF MAIN BENEFITS High in sanitation Stainless steel sieves, FDA-approved plastic parts and the omissi- on of any nails, plush and felt al- low high sanitary standards. In ad- dition, the closed machine outlets prevent any fo- reign parts from falling into the product. High in energy efficiency The electric air flow can be controlled via the machi- ne’s integrated system or the plant control system. The air recycling and use of frequency converter reduce the energy consumption by up to 15% and fresh air intake by up to 90%. Low in operating costs and in physical footprint All wear parts such as sieves, cleaning balls and wear sheets are easily accessible. The sieves can be quickly tensioned and loosened by a quick-clamping system. The perforated sheets on the sieve frame are fixed without the help of nails or screws. Thanks to a clamping de- vice the entire sieve deck can be changed in less than five minutes allowing for maximum uptime. The space saving concept comprises two process steps, destoning and concentrating. The air-recycling version cleans the air in the machine and does not require an external recir- culating-air unit. High in selectivity The integrated dust separation is available with fresh air or air recycling operation. The combination of destoner and concentrator allows for separation of particles with high specific weight, such as stones and glass, and di- vision of flow of materials into high density and mixed fractions. Configurations As a component of the modular Vitaris cleaning system, the Vitaris combistoner MTCH can be combined with ot- her units from the range at a later stage. An air-recycling aspirator or an air-recycling channel can be attached. In combination with the separator, the combistoner can be extended to combi-cleaning system. S e p a r a t i n g with the air-re- cycling aspira- tor MVST The produ- ct separator is a space-saver with remarkable performance. Separating different products according to their specific weight, the compact Vitaris aspirator MVST requires only a minimum of space. Thanks to the centrally placed feeder device, the MVST requires only a minimum of installation height. For non-free flowing products an active feeder device is available. OVERVIEW OF MAIN BENEFITS Space-saving compact design The air-recycling aspirator MVST takes up 30% less in he- ight than systems utilizing air-recycling aspiration channels. High in cleaning performance Connected upstream as the first separation step, it enables the following second step separator to perform more efficiently. Low in operating costs Thanks to the utilization of recirculated air, fresh air consumption is reduced by up to 90%. The air flow can be adjusted either manually at the machine through an integrated frequency converter or recipe based through the plant control system. Configurations Like all machines from the Vitaris modular system, the air-recycling aspirator MVST can be combined with other units from the range at a later stage. It can be flexibly ad- ded to the Vitaris separator MTRD and combistoner MTCH. Separating with air-recycling aspiration channel MVSS Utilizing air-recycling the aspirator efficiently sepa- rates fine impurities from the grain, for example redu- cing mycotoxin content significantly. The air-recycling aspiration channel MVSS is very energy efficient. The improved geometry of the aspiration channel ensures an optimal airflow across the whole width of the MVSS avoiding depo- sits. Meeting highest food safety standar- ds there are no dead spots at the inlet and the aspiration channel is se- aled. Fresh air consumption is reduced by up to 90% and energy consumption by up to 15%. For non-free flowing products, a feeder device is available that distributes the product over the entire width of the sieve. OVERVIEW OF MAIN BENEFITS High in energy efficiency The use of recycled air and efficient frequency conver- ter reduce fresh air consumption by up to 90% and elect- ricity usage by up to 15%. The need for larger sized filter surfaces is significantly reduced. User-friendly air flow controls The air flow is easily and efficiently controlled by a frequ- ency converter. Energy loss that occurs when using traditional air flaps is avoided. The air flow can be adjusted using the integrated controls or the plant’s control system. Product spe- cific adjustments can be made via the plant’s control system. Configurations A part of the Vitaris cleaning system, the air-recycling aspiration channel MVSS can be flexibly combined with an air-recycling aspirator MVST, Vitaris separator MTRD and Combistoner MTCH. Customer case study: The customer had MTRA 60/100 and MTSC 65/120E machines and wanted to replace them. With Vitaris, he was able to renew his machines with our combination cle- aning system. He also saved one floor 3.8 m high and around 5 x 5 m of floor space, where he can now pack his cleaned organic wheat. His advantages are: - New efficient, low-maintenance machines - Space saving for the same work (cleaning) - Possibility to expand into new areas of business CONCLUSION Every mill has its very specific requirements and preferen- ces depending on its size, production volume, production processes as well as considerations for expansion and invest- ment. Given the variety of building specifications and plant layout, what millers require are practical tailormade solutions. The Vitaris cleaning system represents a holistic solu- tion that adapts to your needs. You can add individual machines from the Vitaris system to fit into your existing setup and add other machines at a later stage. The indivi- dual machines in the Vitaris cleaning system can be flexib- ly combined according to your specific requirements. For example: • Vitaris separator MTRD + Vitaris combistoner¬ MTCH (  Vitaris Combicleaner) • Vitaris separator MTRD + Air-recycling aspiration channel MVSS. • Vitaris combicleaner MTKC + Air-recycling aspiration channel MVSS. + Air-recycling aspirator MVST. Whichever initial configuration you choose, the be- nefits of the Vitaris cleaning system will have a tangible impact on the overall performance of your plant. From excellent food safety and hygiene to energy savings, one of the most decisive aspects is the unrivalled ratio of per- formance in relation to physical space.
