Twist Air Pasteurizer & Twist Air Cooler plant - TAP & TAC

The "TAP & TAC" TWIST AIR PASTEURIZER - COOLER is a reliable alternative solution to the traditional linear "pasteurizing and cooling tunnel" working with water, at different temperatures, etc.

• Water is not available or very costly;
• In the dry ambient where water can create troubles in the production and/or in the environmental conditions;
• Abosolutely water free consumption;
• Very easy and friendly cartining - packaging operation in line, with riscks of water damages in the final pallet;
• Less maintence costs, due to the less parts/components in motion as "wear and tear" compared to traditional tunnel;
• Huge useful surface available compared to the traditional linear tunnels;
• Factory space saving compared to the traditional linear tunnels;
• Possibility to change working level - floor during the same processing phases - cycles;
• Minimizing and/or optimizing the production costs due to the continuous operation - running cycles, and lower manpower involved;
• Possibility to treat different type of products and/or packed products in the same time - same belt;
• Final product standardization;

The "TAP & TAC" can find easily applications into:

• the traditional preserved food factory as fruits or vegetables;
• in the pasta sector for long shelf life type pasta "stabilized";
• meat sector;
• ready meals sector;
• bakery sector;
• sweet bakery sector;
• chemical or pharmaceutical sector;
• etc.

The "TAP & TAC" TWIST AIR PASTEURIZER - COOLER here included basically is solution made by a "twin" spiral conveyors where the:

• Each spiral is located inside an insulated cabin made out of sandwich panels, specifically designed for each application TAP - TAC working conditions.
• The chambers are positioned keeping a certain distance in the between to avoid interference and/or any "Thermal Bridges".
• Both system are using either "Hot Air" or "Cold Air" recycle air flow.
• "Hot Air" or "Cold Air" are generated through heat excahgers using steam or Freon/Ammonia.
• In case of special packaging and/or products the passage between the two belt is provided by a smooth passage thanks to "pen type belt".
• Belt/s can be in flexible stainless steel type or in modular flexible plastic material, upon specific preference and applications.
• In order to obtain the quickest and the most efficient thermal process TWIST AIR PASTEURIZER COOLER is designed for:

- air speed circulation (4 -10 m/sec) of hot and cold air in the chambers.

Upon specific application TAP & TAC" can be provided with:

• HMA "High Moisturized Air", mainly in the TAP chamber, to improve the thermal exchange and minimize the time;

• due to some particular locations TAC can have the A/C design, with allow to have a double cooling circuit, using external ambient air in the 1st half, and a refrigerated air in the 2nd half for the final cooling. This configuration depends on the type of product and to the geographical and weather conditions, but when ever this application can take place give a big saving in terms of cost of production - energy saving.

- higher thermal exchange on the product surface;

- quicker and faster thermal "hot and cold" penetration;

- due to this the quality of the final product is not particularly effected and it's final characteristics are like the fresh one, and mostly with minimum risks of having "brownish and/or coocked" effected final products;

- Standardization of the final product;

The TAP & TAC solution reassume the conditions and the parameters needed to approach correctly the modern food industry. Machine design concept applied in this unit is the:

• The unit doesn't have any mezzanine floor and or intermediary platform, to avoid any excess of points where dirtiness can be accumulated making more difficult the cleaning operations;
• Drum is without lateral openings to improve the air guidance and to minimize the possibility to accumulate dirtiness, in points where access is not easy if not possible;
• Central Drum drive supported by roller bearings;
• Stainless steel flexible belt or plastic belt for special application such as sticky or tender products with low water content products;
• Spiral structures made of stamiess steel;
• Very high mechanical reliability of spiral belt conveyor.
• Reduced belt wear and elongation thanks to low tension drive system (the belt is pulled by means of dynamic friction on the total length);
• Machines design "maintenance free";
• Low maintenance cost and low spare parts cost due to utilisation of high quality commercial components;
• Machine design "lubrication free";
• No possibility of product contamination;
• Belt and drum driving gears usually positioned outside the insulated cabins, avoiding any risks of contaminations due to some oil leakages;
• PLC 6" black and white type with touch screen supervision system
• All mechanical parts are in stainless steel, food grade plastic material, special anodized aluminium;

Air - flow concept applied in this units is the:

• The lateral aprons to guide the airflow on the opposite side of the evaporators are on easy access design like door open able or sliding, but in any case easy acces is granted all around;
• Possibility to have bi-directional air flow due to the a special axial resersabie fans;
• Axial fans to optimize the energy consumption;
• Flat fin evaporators - heat exchangers with low air pressure drop with decreasing flat fins spacing;
• Heat exchanger are usually either in stainless steel or aluminium or copper or galvanized steel (upon specific applications and/or as per customer preference)

As conseguence we can obtain:

• Longer working cycle due to:
• THE EVAPORATOR DIMENSIONS AND DESIGN WITH DEACREASING SPACING
• VERY LOW A T° IN THE RECYCLE AIR FLOW
• As (option) we can provide "symmetrical" bi-directional air flow design evaporators on the air entrance assuring the same performances even once we revert the air flow. This solution is particularly appreciate in the factory which are seasonally working, and provide quite long running time delaying the stoppages due to the defrost cycle, increasing enormously the daily production.

• Fully automatic washing system (optional) with loose water;
• C.I.P. "Cleaning in Place" system with the possibility to use basic - acid - detergent and disinfectant solutions (optional)
• PLC 10" colour type with touch-screen supervision system (option);
• Ethernet configuration;
• Modem for teleservice assistance;
• Reverse osmosys system for HMA configuration;
