AWS represents the highest
quality, new biotech and pharmaceutical manufacturing equipment
|
| |
PennTech Machinery Corporation (formerly Mengibar Applied Technologies) was
founded in 1992. In the early 1990's the company offered a medium to high
output rotary vial washer, the RW-1150 and a dual trayloader, model TL-200.
Since that time, success in performance and reliability has led to an ever
increasing and diverse product line. PennTech has increased its offering to
include a RW-800, the industries only low to medium throughput (specific)
continuous rotary vial washer, as well as a single tray trayloader, the
TL-100. The company is slated to introduce a revolutionary filling
machine (specifically for parenteral lines) within the 2006 timeframe.
PennTech has positioned itself as a major contender/supplier of equipment for
the pharmaceutical, biotech and animal health industries. PennTech continues to
develop new products and improve upon existing ones to accommodate the changing
needs of our customers, while never losing sight of its commitment to
excellence.

Key Benefits of a
Rotary Washer
-
Cleanliness
There are no moving parts in the washing chamber (except for
the central turret).
In-line vial washers with chain based drive mechanisms inherently create
more particulates than rotary vial washers.
-
Functionality
Each vial size has a dedicated set of change parts. Each set
of change parts is designed to handle a specific size vial. In other
words, each vial is optimally exposed to internal and external water/air
spraying.
In-line vial washers, to the contrary, use vial holders
(buckets) made for all vial sizes, from the smallest to the largest.
This is a compromise to the effectiveness of the washing function.
-
Visibility
Due to the transparent polycarbonate cover over the washing
chamber, the total washing function can be visually inspected. This is
practically impossible with in-line vial washers.
-
Compact Size
The rotary design allows for a small footprint. In fact, the
PennTech machine occupies 2.7 meter2 (1.9m x 1.4m) and is the
most compact vial washing machine on the market today.
-
Single File Container Outfeed
The cleaned vials leave the washer in a single-file fashion.
This means that the vials are immediately available for trayloading or
for transporting to the filling machine in the clean room. In addition,
when continuous sterilizing is required (using a sterilization tunnel),
the vials can be pushed onto the tunnel conveyor in a full loading
pattern. This is a significant advantage over in-line vial washers
whereby the loading pattern is less than optimum. This may result in
"cold spots" in the sterilization tunnel.

Controversy of Stationary
Nozzles versus Penetrating Nozzles
PennTech has chosen stationary nozzles, as opposed to penetrating nozzles.
There are several reasons for this choice:
-
Penetrating nozzles move in and out of the vials
Everything that moves generates particulates.
This is in violation with the function of a vial washer; i.e., to remove
particulates.
-
Tests have shown that stationary nozzles are as effective as penetrating
nozzles
The reason for
this is due to the high velocity of the waterjet exiting the spray pipe;
the stationary nozzle maintains its convergent nature as if an invisible
spray pipe is surrounding the waterjet. Even small, 2 ml vial with a 13
mm neck finish are effectively cleaned.
-
Penetrating nozzles may hit the neck finish of the vial and bend
Bent nozzles
are not only ineffective; they may jeopardize the validation of the
batch in addition to a higher rate of broken glass.

Operational Highlights
-
From the rotary
infeed table, vials are automatically loaded into dedicated carriers
unique to each ind. vial size.
-
During the washing
treatment, the vials are indexed in an inverted position in such a way
that the bottles line up exactly with the spray pipes across the neck
openings.
-
Water and air
spraying cycles start when the vials are lined up with the spray jets
and stop during the indexing movement.
-
The
washing cycles are selected by the customer. Selection
is made using combinations of the following:
-
Recirculated WFI
(water for injection)
-
Virgin WFI
-
Sterile Air
-
For the RW-1150,
there are sixteen indexing positions, thirteen of which can be used for
the washing treatment. On the RW-800, there are 8 positions, 6 of which
can be used for different washing cycles.
-
The treatment time
with WFI depends on the selected washing program and the selected output
rate and may vary between ten and thirty seconds. In addition, sterile
air blowing time may vary between 7 and 20 seconds.
-
The linear motion of
the outfeed pusher as well as acceleration, deceleration and positioning
is automatically selected (via PLC) for the vial size in use.
-
The operator
controls the machine through an Allen Bradley PanelView 550 or optional
PanelView 1000 operator interface with programmable input keys and error
messages.
-
The changeover to a
different vial size requires only the use of a 5mm Allen key and is
accomplished in less than fifteen minutes by one operator
-
In whole, the machine
consists of the following components:
-
Infeed turntable
with positive drive infeed mechanism
-
Washing chamber
with vial carriers
-
Spray pipes
-
Central indexing
turret with drive mechanism
-
Water/air distribution

-
