Tetra Pak® Aseptic Tank VD Application For intermediate storage of low-acid food products under aseptic conditions. This fully automated aseptic tank is available as a separate unit or as a component in our best-practice lines for UHT dairy products, with guaranteed performance. Working principle Tetra Pak ® Aseptic Tank VD is sterilised by steam at a minimum temperature of 125°C for a period of time. It is then cooled by water circulating through the cooling jacket. During cooling, sterile air is fed into the tank to prevent vacuum formation. During production, sterile air fills the tank space above the product level. The pressure is automatically controlled to maintain the feed pressure required by the filling machine in operation. As option, Tetra Pak Aseptic Tank VD can be equipped with an agitator. This is recommended for products, that can separate in the tank during storage (e.g. chocolate milk and juice with fibres) and to even out the product temperature. A valve cluster module with control panel directs product flow, sterile air, cleaning liquids and steam. During production a steam barrier (110°C) is applied to protect the product from contamina-tion. After the filling machines, the end valve cluster prevents reinfection. The tank is cleaned in place by a central CIP system. Since tank operation includes high-temperature sterilization followed by cooling, the tank is designed to be completely implosion-proof. The tank is manufactured in accordance with the European pressure vessel code (PED), but can be manufactured to comply with other codes on request. One of the three stainless legs is equipped with a load cell which measures the content of the tank and shows the reading on the panel. Tank operation is fully automated and production interlocks are included for safety reasons. The operator only has to initiate the process steps: tank sterilization, production and CIP. The tank is operated from its own programmable control in the control panel
