Vacuum Controlled
Linear Flow (VCLF) Percolation System
The
optimal percolation system
From the arguments presented in the Production Methods page it is
possible to describe the factors that would ultimately define the
optimal percolation system.
Cylindrical Percolation Column
This would reduce the
factors that result in a non-linear flow through the system.
Constant Column Head Pressure
This would promote a
constant extraction medium velocity through the system and therefore
reduce problems associated with turbulence and exit-valve
compensation caused by constant changes in head-pressure.
Packing Density Compensation
This would allow for
greater operator freedom and reduce system time-down; which can be
caused by having to re-pack the percolator due to clogging.
Automatic Percolation Velocity Adjustment
This would allow for
greater operator freedom, which ultimately increases productivity.
Vacuum Controlled Linear Flow Percolation System
With these factors in
mind, Asclepius Herbal Consultancy has developed a percolator and
percolation control system, which in our opinion approaches the
optimal specifications for a percolation apparatus.
Asclepius Herbal
Consultancy’s Vacuum Controlled Linear Flow (VCLF) Percolation
System utilises electronic monitoring and control of the process
variables in the percolation system to ease production operation and
to enhance extract quality.
Automatic
filling – Pre-dose monitoring of the extractive medium
Constant automatic
filling under the percolation process is coupled to pre-dose
(reservoir) monitoring, which automatically fills the percolation
column and adjusts the control system process in the final stages of
percolation.
Extraction
medium head-pressure – control of head-pressure
Adjusting
head-pressure under the percolation process is the key to the entire
VCLF system operation enabling control of percolation column filling
and percolation velocity.
Percolation
velocity – laser-optic controlled monitoring
By monitoring the
percolation drop frequency, the system can control the percolation
velocity within a user definable output range from 1-250 drops per
minute.
Packing density
– Compensating for a wide variation in packing density
The control system
tolerates a wide variation in the packing density by using
electronically controlled compensation to control percolation
velocity under varying packing density parameters.
Computer control
of the entire percolation system – Run up to 4 percolation systems
from one computer
Asclepius
Consultancy’s VCLF percolation system reduces the amount of labour
intensive operations in the production process. The control program
is Microsoft Windows® based and has been developed to give a user-friendly
graphical presentation of the percolation process for easy
monitoring of the production process.
Furthermore,
percolation run-data is logged into the computer automatically and
can also be supplemented with user defined values.
