Continuously operating in-line Greerco mixers from Chemineer are successfully handling a delicate dilution application in the manufacture of washing-up liquid by a company in Western Germany.

Equipped with a variable speed drive that adjusts to actual production capacity, the in-line Greerco mixers first carry out the dilution (with deionised water) of FAES (fatty acid ester sulphonate) with 70 % active matter, which is taken directly from the storage tank.

Mixer / agitator design and manufacture

Ever stringent cleaning and sterilisation requirements, combined with the increasingly high standard of food and pharmaceutical products has prompted one agitator manufacturer to give its customers the opportunity to become actively involved in the detail design of their machine.

The government’s aim of achieving targets for zero food and packaging into landfill by 2015 have clearly focused attention on ways of developing technology that can contribute to a significantly reduced reliance on carbon based fuels and reducing emissions. Of particular interest to SYSTEM MIX LTD is the potential for converting problems associated with the disposal of organic waste materials into energy generation through the process of anaerobic digestion.

Conventional mixers and dispersers are expensive to operate because of their inefficiency. The Fujikin motionless mixers are not only highly efficient as they have no moving parts but can save operating time and have compact, in-line, easy to clean bodies.

A new wide bandwidth active upconverting mixer, the LT5578 from Linear Technology, delivers high dynamic range performance from 400MHz to 2.7GHz, supporting all of the allocated LTE (Long-Term Evolution) broadband wireless services. At 900MHz, the mixer offers 27dBm Output IP3 linearity and best-in-class noise floor of -160.5dBm/Hz at an output level of -5dBm, enabling outstanding transmitter dynamic range. In addition, the mixer has 1.4dB conversion gain with integrated RF balun transformers that provide a single-ended RF output and LO (Local Oscillator) input to simplify designs while reducing external component count. Moreover, the device’s LO input is internally buffered, requiring a drive level of only -1dBm. This results in an outstanding LO-to-RF leakage of -43dBm.
