Small S cale E xtracti on Plant, ATEX
The SPX e&e Series small scale extraction plant is designed to extract small batches of raw material using water or alcoholic solvents. The
gasket material can also be adapted for other solvents (acetates, alkanes, etc.) on request. The plant is equipped with 2 percolators, each
with 50 litre volume capacity. Additionally, the plant features a condensation unit consisting of a condenser and a stainless steel vacuum
pump, together with a solvent balance tank and a miscella outlet.

Evaporation
Small S cale Evap orati on Plant, ATEX, f or th e con ce ntrati on of li qu id e xtracts
The SPX e&e Series small scale evaporation plant is designed to concentrate small batches of extracts or other liquid products using water
or alcoholic solvents. The concentration rate is limited to the viscosity of the concentrated liquid (up to approx. 500 cP). The plant consists
of a plate evaporator with a downstream centrifugal separator. The evaporated vapours are condensed in a plate heat exchanger. A vacuum
pump is connected to the condenser, and the vacuum can be adjusted between 50 and 800 mbar. The evaporation temperature can be
adjusted according to the product specific boiling curve through the applied vacuum, which also enables concentration of temperature
sensitive extracts.
