Mavitec

Mavitec is specialised in the design, manufacturing and installation of high quality process systems and equipment for the ‘rendering’ industry. Our systems recycle animal protein by-products by separation of liquids (oil, water, fat, solvent, etc.) from solids. We service the rendering industry with our knowledge and technology. Our systems are for meat-packers, slaughterhouses and renderers. Mavitec operates worldwide en is with proud the exclusive representative of The Dupps Company located in Germantown OH – USA, the world’s leading company in designing and manufacturing rendering equipment.

Mavitec has also great experience, due to the long history in the Rendering industry, in the design, manufacturing, supply and installation of screw conveyors / transport systems in all possible designs for each desired product and application.
Mavitec is further active in the design, manufacturing and programming of complete electrical control panels for the process industry. This with PLC/PC with or without touch screen controls for a wide range of applications.

Mavitec is able to engineer, coordinate and if required install single components up to a complete production line from A to Z. Also maintenance, revision and servicing are an option that Mavitec can supply. Mavitec has its own mechanical and electrical engineering department which has direct lines with the planning and production floor. In this way we limit any possible communication errors to a minimum.

Achieving customer satisfaction is the priority of our company and this philosophy is our key to growth and success. Mavitec works according the rules of ISO9000:2000 and due to this quality policy we guarantee our clients the desired quality level, so that we can keep our slogan “Customer service is our growth!”

After rendering, the materials are much more resistant to spoiling. The fat can be used in animal feed, in soap-making, in candles, as a raw material for biodiesel production, and as a feed-stock for the chemical industry. The bone and protein becomes dry particles known as meat and bone meal. For many years meat and bone meal were fed to cattle. This practice is now prohibited in developed countries because it is believed to be the main route for the spread of BSE (mad-cow disease). Meat and bone meal is still fed to non-ruminant animals in the United States.

Tallow, derived from beef waste, is an important raw material in the steel rolling industry providing the required lubrication as the sheet steel is compressed through the rollers.

In the absence of the rendering industry, the cost of waste disposal of waste animal material would be very high and would place a significant economic and environmental burden on areas involved in industrial scale slaughtering.

The development of rendering was primarily responsible for the profitable utilization of meat industry by-products, which in turn allowed the development of a massive industrial-scale meat industry that made food more economical for the consumer. Rendering has been carried out for many centuries, primarily for soap and candle making. The earliest rendering was done in a kettle over an open fire. This type of rendering is still done on farms to make lard (pork fat) for food purposes. With the development of steam boilers, it was possible to jacket the kettle to make a higher grade product and to reduce the danger of fire. A further development came in the nineteenth century with the use of the steam “digester” which was simply a tank used as a pressure cooker in which live steam was injected into the material being rendered. This process was a wet rendering process called “tanking” and was used for both edible and inedible products, although the better grades of edible products were made using the open kettle process. After the material was “tanked”, the free fat was run off, the remaining water (“tank water”) was run into a separate vat, and the solids were removed and dried by both pressing and steam-drying in a jacketed vessel. The tank water was either run into a sewer or it was evaporated to make glue or protein concentrate to add to fertilizer. The solids were used to make fertilizer.

Technological innovations came rapidly as the 20th century advanced. Some of these were in the uses for rendered products and others were in the rendering methods themselves. In the 1920′s, a batch dry rendering process was invented, in which the material was cooked in horizontal steam-jacketed cylinders that were similar to the fertilizer dryers of the day. Advantages claimed for the dry process were economy in energy use, a better protein yield, faster processing, and fewer obnoxious odours attending the process. Gradually, over the years, the wet “tanking” process was replaced with the dry process, so that by the end of World War II, most rendering installations used the dry process. In the 1960′s, continuous dry processes were introduced by The Dupps Company, one using a variation of the conventional dry cooker and the other making use of a mincing and evaporation process to dry the material and yield the fat. In the 1980′s high energy costs popularized the various “wet” continuous processes. These processes were more energy efficient and allowed the re-use of process vapours to pre-heat or dry the materials during the process.
