Mixing, dissolution and cooking systems

CUSTOMISED SYSTEM ACCORDING TO YOUR NEEDS

Ing. A. Rossi designs and manufactures customized installations suitable for the execution of the most different mixtures for batch or continuous, both for solid food products and fluid. In the tomato processing field, dissolution systems which allow obtaining from concentrated both for batch and continuous, sauces with the desired concentration are manufactured. We also manufacture complete cooking lines for the processing and production of jams.

PASTEURIZATION TO INCREASE STORAGE TIMES

Once the production chain is completed, the elements responsible for product degradation must be inhibited in order to save the product preservation. Ing. A. Rossi uses a tubular pasteurizer with which the product to be packaged is brought to the pasteurization temperature. This type of processing is suitable for concentrated, semi-concentrated, fruit juice or fresh products, previously transformed to a direct packaging in glass, plastic, tinplate or brick.
The exchanger is composed of 4 concentric pipes in order to heat the product on two cylindrical surfaces and guaranteeing a uniform temperature inside. The thermo vector fluid is water heated by a direct steam injection.

Tube in tube and scraped surface sterilizers

STERILIZATION AND COOLING OF THE PRODUCT

In order to extend the preservation of treated products aseptic packaging, which consists in filling polifilm pre-sterilized bags with sterilized product at room temperature, is used. The product sterilization and cooling is obtained with tube in tube exchangers.
Composed of 4 or 2 concentric tubes, the exchangers include:

  • A product heating section with water overheated by a direct steam injection;
  • Up to the sterilization temperature, depending on the nature, pH, free water and previous treatments of the product;
  • A maintenance section at sterilization temperature and two cooling sections, the first generally cooled by tower water, and the second by refrigerated water or always by tower water.

Equipped with a washing and sterilization system with cooling constant pressure and with barriers in the dwelling and cooling sections (in order to prevent and avoid environmental contaminations), the Ing.A.Rossi sterilizers guarantee the right aseptic degree of the treated product and its preservation and stability in the warehouse.

SCRAPED SURFACE EXCHANGERS FOR COOLING

The presence of scraped surface exchangers allows the containing of circulation pressures , in periods when the high production of high-viscosity products and concentration that might affect at high temperatures the product texture (Bostwick and Blotter).
To avoid this, Ing.A.Rossi offers tube in tube heat exchangers for heating and temperature maintenance stages and scraped surface exchangers for cooling stages. This solution well suits tougher products in which concentration and viscosity are essential characteristics.
Completely scraped surface solutions may be developed for particular products with suspension ingredients or with particular viscosity such as ready sauces and purees, as well as in systems in which the great possibility of variations in the capacities would not be applicable to the pipe system.

Aseptic fillers

Aseptic fillers

SINGLE HEADED OR DOUBLE HEADED POLIPACK ASEPTIC FILLERS

The POLIPACK 200 M aseptic fillers are for 220 Lt (60 gl) bags and may be single-headed (model 1-200 M) or double-headed (model 2-200 M). Both models have loading and unloading rollers, a filling workstation area equipped with a mobile head, able to move vertically during the filling stage and a monitoring area.
 
A label printer and a jib crane to move full barrels and place them on pallets are provided too.  A system consisting of loading cells guarantees an accurate filling while steam barrels and various controlling instruments avoid the contamination of the product and of the filling environment.

EQUIPMENT AND PERFORMANCES

POLIPACK aseptic fillers can be combined with the small bags adapter (with capacities from 5 to 20 Lt), equipped with a continuous film bag supplier and discharge roller conveyor. The integration of the adapter’s operating parameters with the ones of the PLC filler allows the perfect compatibility of the two elements.

The aseptic fillers POLIPACK 200/4 - 1,000 M for bags having capacities of either 220 lt (60 gal) or 1.100 lt (300 gal) may be provided in a single-headed (1-200/4-1.000 M) or double-headed (2-200/4-1.000 M) model. Both models are equipped with motorized rollers conveyors for pallets/bins feeding and ejection, a mobile filling head, a monitoring workstation and a rotating roller conveyor underneath the filling head. This one allows the pallet rotation in order to place each of the 220 lt four bins right under the filling head. During the filling operation the head moves vertically to avoid the weight of the filled bag from causing laceration. An accurate filling is guaranteed by the presence of loading cells and flow meters, while steam barriers ensure an aseptic filling operation.
