«SAK» stands for «Silo-AustragsKegel» , which means in English  «Extraction cone valve for silo». The SAK is designed to control the discharge of powder or granulates out of silos.

The SAK is particullarly efficient in the following cases:

• For a «fast» silo discharge (high extraction capacity)
• For dosing the discharged powder or granulate
• For discharging a silo at different flow
• Garanty a proof closing of the silo (self closed without energy)
• For extracting and discharging “difficult” flowing powders

Working Principle:

• The cone valve is guided in a hopper located at the bottom of the silo
• The cone valve is lifted by a pneumatic bellows
• The adjustment of the opening is set by the stroke of the guiding rod one for  all (basic version)
• The continuous adjustment is set by a pneumatic drive adjusting the stroke  from 0 to 100% (dosing version)
• Dosing of the discharged product by adjustment of the opening of the cone  valve versus the weight on scale, through an interface terminal IT 9000.
• Vibration of the cone in open position

The «LIQUEFYER» is an extractor designed for small size silos, hoppers and dosing vessel.

It is particularly recommended for the following cases:

• For extraction of «difficult» flowing powders
• When «CIP» is required (with a DYNAFORM membrane)
• For corrosive powder or cleaning agent
• For abrasive powder

 Working Principle:

• Scratching of the inside wall of the LIQUEFYER by means of a rotating blade. The blade is actuated by an electrical motor
• Pushing of the powder toward the center of the LIQUEFYER allowing a regular and continuous powder extraction
• When the LIQUEFYER is equipped with a DYNAFORM membrane either in FEP (Fluoro Ethylene Propylene) or in PUR (Poly Urethane) the product is no more in contact with any mechanical part
• When the LIQUEFYER is equipped with a DYNAFORM membrane it is fully «CIP compatible»
• The LIQUEFYER may be mounted on any existing equipment by adapting the top and bottom flanges accordingly
