A record production of pasta of teeth needs motorreductores big and strong

The manufacturer of stirrers industrial to measure Ekato has increased to more than the double the biggest model of his line Unimix to carry out, like this, the greater system of discontinuous production of pasta of teeth in the world. Two mezcladores, each one with 10.000 litres effective volume, produce of 6.000 to 11.000 kg of pasta of teeth by hour, in function of the concentration of the product. Therefore, it has more than triplicado the production. The specialist in accionamientos Nord Drivesystems backed the development of the new systems of record size.

A lot of manufacturers of world-wide scope are interested in concentrating the capacity of production in only some places. The industries for the hygiene and the personal care follow definitely this tendency. In consequence, the demand of products such like pasta of teeth is every time greater. Besides, in each place produces a wider range of variants. Therefore, the modern plants have to be able to produce big volumes and at the same time provide the maximum versatility. With this complex task in his sight, Ekato Systems of Schopfheim, in the extreme south of the Black Jungle, has built a new plant for the discontinuous production of pasta of teeth.

The new systems Unimix, promoted by motorreductores industrial Nord: with a record volume of 10.000 l each one, form the greater plant of the world of production by batches of pasta of teeth.

Current state of the technology

The maximum capacity of the plants of production of pasta of teeth was used to to be between 4.000 and 5.000 litres, with some approximate productions of 2.000 to 3.000 litres by hour. It is possible the continuous production or by batches. The continuous systems allow a high performance, but are not very versatile regarding the changes of product; place that the different ingredients sometimes require his own technology of distribution and mix, the changes in the recipes are used to to cause conversions and readjustments. Also it goes in at stake that the dental cream can not be easily reelaborada when it is not sufficiently homogénea. The greater challenge with continuous plants is to ensure the uniform dispersion of the active ingredients such as the fluoride of sodium, even after changes in the systems of dispensación. On the other hand, the tax of production of existent discontinuous plants can not increase significantly without big modifications in the equipment of the plant. With the end to satisfy the demands of a manufacturer of pasta of teeth, Ekato had to build plants bigger.

Design of the mezclador of production

The systems of production of pasta of teeth basically consist in a container that can vaciar, with an agitador, a homogeneizador and diverse systems of dispensación for the introduction of the ingredients in the process. The liquid ingredients or measure and afterwards enter by empty in the container or dispense by methods gravimétricos. The dusts and thickeners to increase the viscosity can add through the homogeneizador integrated or pour in the container through a valve in his base.

The complex calculations for the enlargement

For a mezclador of greater dimensions, Ekato had to determine the doses and the times of dispersion of the components, the times of mix and homogenisation, the values of empty and the provision of the agitador and the homogeneizador necessary. The agitador and the homogeneizador configured in accordance with the equation of performance of the mix for the technology of mixed.

In base to his wide experience, Ekato determines the coefficient of power ‘Ne' (or number of Newton) corresponding to each impulsor and the curve of specific viscosity of the product. In addition to the concentration of the product, the equation contains, on the other hand, the speed and the diameter - with exponents 2, 3, or even 5, these values are especially important. That's why the correct configuration of the accionamientos of the agitador and the homogeneizador is crucial. The provider of accionamientos Nord had to configure the motors and reductores in accordance with the provision according to the calculations of Ekato, and so that they were the most efficient and durable possible. Since the accionamiento of the agitador is installed in the top of the mezcladora of production, has to be so compact as it was possible in spite of the high performance required.

An agitador with accionamientos so big like a car

This application depends on the quality homogénea of the product, requires speed and continuity. The radial and axial loads in the axis of the agitador, are very high because of the big viscosity of the product, have to take into account to configure the accionamiento. Nord Drivesystems Configured and supplied two motors of 250 kW with reductores industrial that provide nominal pairs of exit of 242.000 Nm. Nord Is the only world-wide manufacturer that produces reductores industrial so extremely big of this rank of power in a carcasa Unicase of an alone piece. Therefore, the motorreductor of 3 trains of gears type SK 15407, although of an impressesive size, keeps on being relatively compact, since the design Unicase allows greater threads to be able to bear upper strengths.
