APPLICATION
stainless steel aspetic pressure Tank is a fully automated unit used for the buffering (intermediate storage) of liquid food products under aseptic conditions.
This advanced aseptic tank is available as a separate unit or as a functional component in our integrated lines for all applications (dairy, beverage and prepared food). The unit comes in a range of three models and tank sizes with a large number of options including different agitators, can advise you on the most suitable tank model for your particular application whether your product is high or low viscosity, with or without fibres, with smaller or bigger particles, etc…
HIGHLIGHTS
• Uncompromised food safety
• Maximize production flexibility
• Preserve high product quality
• Reduce product losses
• Solutions for all types of products
• Long operating time
• Ergonomic design and serviceability
• Simplified line integration
WORKING PRINCIPLE
The Tank is sterilized by steam at a minimum temperature of 125°C. It is then cooled by water circulating through the cooling jacket. During cooling, sterile air is fed into the tank to prevent vacuum formation. After sterilization, the aseptic tank is kept in aseptic conditions with an overpressure of sterile air and with steam barriers(110°C). During production, sterile air fills the tank space above the level of the product. The pressure is automatically controlled to maintain the feed pressure required by the filling machine in operation. A number of agitator solutions are available to match product or application needs. A valve cluster module with a control panel directs product flow, sterile air, cleaning liquids and steam. Placed after the filling machines, the end valve cluster prevents reinfection. The tank is cleaned in place (CIP) by either a CIP unit or a central CIP system. 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. Keep food safe and maximize production flexibility!
BASIC DESIGN
The tank body is manufactured in accordance with the European pressure vessel code (PED), but can be manufactured to comply with other codes on request. Since tank unit operation includes high-temperature sterilization followed by cooling, the tank is designed to be completely implosion-proof. The tank unit is operated from its own programmable control in the control panel, or remote from, for instance a control room. However, if used in combination with one of our heating units, it can be operated from the PC panel of the heating unit instead, saving the cost of a operator panel on the tank.
pressure ASEPTIC TANK
Tank is a platform-based unit that provides a wide range of flexible solutions with different capacities and options. The model is best suited for low to medium viscosity products with or without smaller particles and fibres. This vertical tank has a cylindrical cooling jacket, manhole, CIP nozzles and safety rail. The tank includes a load cell solution for weighing the contents and
the level indication is shown on a control panel. There are connections for product, steam, cooling water, air and CIP liquids. The valve cluster module has frame-mounted pre-assembled valves, sterile air filters, safety features and air pressure equipment for emptying the tank and a control panel. There is also an end valve cluster. In many cases, good agitation is important for the model. An agitator solution is recommended for products that can separate in the tank during storage and is also recommended to even out the product temperature. Depending on the product or application needs, a number of agitator solutions are available. The unit is factory tested before delivery, thus ensuring easy installation. The control system is Siemens or Rockwell and the HMI (human-machine interface) solution is based on the graphic design.
