The NEAEN Pilot vacuum processing plant

The NEAEN Pilot vacuum processing plant is an ideal solution for the production of pilot batches and the industrial manufacturing of a wide range of products from small to medium capacity.

With its low cost and versatility in the types of products produced, NEAEN Pilot is the optimal solution for start-ups and for the release of pilot batches, experimental formulas, and testing of new products.

Design and Functionality

The plant’s design consists of a working vessel with an insulating layer and jacket for heating/cooling. A low-speed agitator with scrapers has a top drive. A rotor-stator homogenizer is integrated in the bottom of the operating vessel. The working bowl is fixed to the locking rotary supports. The product can be unloaded by tilting it ( manually or mechanically, depending on the volume of the vessel). The cover is easy to lean back (manually or using gas-filled shock absorbers in the rear), and it is sealed with four clamps in the closed position.

Depending on the customer’s needs, varying degrees of automation can be provided: weighing and dosed feeding of ingredients, temperature controlled heating and cooling, controlled melting and emulsification processes, homogenization, regulation of the agitator speed, and the degree of vacuum.

Evacuation – the process of removing air that reduces the temperature of the processing of the product, thus keeping its best consumer properties.

Mixing – A specially shaped agitator and shape of working vessel provide uniform mixing of the product without dead zones. Special “floating” scrapers do not allow the formation of burnt-on materials on the walls and contribute to the maximum transfer of heat or cold from the walls to the product in a thin layer.

Homogenization – Integrated in the tank bottom, the rotor-stator homogenizer provides a rapid and effective dispersion, emulsification, and homogenization of the particles with a size of 3 microns (or less on demand). The resulting product has an attractive appearance, a stable, homogeneous structure, and does not separate. It has a long shelf life. A homogenizer is used for the recirculation and discharge of the product. There is no need for additional pumps. It improves the hygiene of the plant and ease of maintenance.

Heating and cooling – The heating and cooling jacket allows the implementation of heating, melting, and cooling processes in one unit.  The “direct steam injection into the product” option can significantly reduce the heating and cooking time in a batch.

The automated control system eliminates human error and ensures a consistently high quality of the finished product from batch to batch.

Odpowietrzanie – proces usuwania powietrza, który zmniejsza temperaturę przetwarzania produktu, a tym samym zachowuje jego najlepsze właściwości konsumpcyjne.

Mieszanie – specjalnie ukształtowane mieszadło i pojemnik roboczy zapewniają równomierne wymieszanie produktu bez występowania stref martwych. Specjalne “pływające” lemiesze nie pozwalają na osadzanie się przypalonego produktu na ścianach pojemnika i wpływają na maksymalizowanie wydajności przepływu energii cieplnej między ścianami pojemnika oraz produktem poprzez cienką jego  warstwę.
