2- Used milk processing plant

The plant was designed on the ground of the following project hypothesis:

2.1. Filling capacity
2.2. Process time
2.3. Product specification

2.1. Filling
the plant is dimensioned for feeding aseptically four filling positions:
Pos. 1 (normally in operation) One filler with complete auxiliary packing
Pos. 2 One filler installed for mechanical and sterilization test
Pos. 3 One filler on trial test before delivery
Pos. 4 One filler for staff training

Pos 2 - 4 can be connected once at a time only.
The possibility of feeding more than one filler contemporary is not
Position 1 gives the possibility on automatic or filling 2 different
products at the same time.

2.1.1 Each filler has a capacity:
with 250cc size 21'000 pcs/hour corresponding to 5250
350cc 21'000  7'350 l/h
500cc 21'000  10'500 l/h
1000cc 13'000  13'000
2000cc 7'000  14'000 l/h

Process times:
Autonomy times
The plant connected with a filler will produce with:

250 cc size (5250 l/h) for a time of 2h 13 min

Plant consumptions
The plant consumptions have been calculated on the normal pilot plant
production scale. Average and peak consumptions are listed.

The total steam consumption does not exceed 400 Kg/h at 7 bar. The batch
preparation consumption in the mixing section, if considered contemporary,
is not foreseen. A steam boiler is provided in our supply.

Sections A.00 / B.00 / C.00
Steam consumption takes place only during the cleaning for a period of
roughly 10 minutes.
Peak / 300 kg/h

Section D.00
Sterilizing 70 kg every sterilizing cycle
Peak: 200 kg/h during 20 minutes
Production: 30 kg/h ton.
Average: 100 kg/h

Peak: 400 kg/h during 15 min

Electric power
The installed powers are listed in the description of each item and we
assume 380 V 3-phase, 50 HZ
Total installed power: 105 kW

We consider process potable water at 20 C with a pressure of 3Kg/cm2. The
water required from the steam boiler and the ice-bank is included.

(*) Note: This flow-rate is required only to have a proper cleaning of the
fillers and the relevant feeding line because of the very high peak capacity
of the fillers in 2 lt. Size.

Ice water
The ice water at 1 C is required only:
in the mixing tank if an extra cooling for overnight stand-by is necessary
in some special uses of the UHT plant where filling temp. below the room
temperature is required
Therefore the total consumption does not exceed 60'000 Kcal/h
An ice-bank to provide the necessary ice water is included in our supply:

Compressed air
The consumption of compressed air a 7 bar necessary for the pneumatic valves
of all the installation is roughly 5 Nm3/h

Section G00 Automation

General Description
Aim of the automation
The proposed automation system is of a high level type able to comply with
the first-rate standard of the used engineering components. The design parameters mainly obtain:
Efficiency of operation

Reliable software resulting from processor's experience
Reliability of components and configuration
Easy use by inexperienced operators with no mistake possibility Easy and immediate dialogue with operators using the plant for the first time, guided in the operations performance by the menus, graphic and mimic indications displayed on the video.
Easy use by experienced operators who can make up autonomous programs with a developed and simple language
Completely independent and multi-level manual operations.
Reliable and easy filing structured on floppy disks.

General features:
With reference to draw there are three main components of the system:
General control board
Power section
Plant interfacing box

General Control Board:
The GCB is the direction desk including all the control instruments, the computer, the mimic panel, the video display, the printer etc. From this control board the operator can perform all the operations to be made either automatically and/or manually by running the programs involving the UHT
plant, the aseptic tank unit, the mixing, the cleanings etc.

Power section:
The power section is contained in a cabinet and includes all the controls of the motors which are controlled automatically and/or manually from the GCB.

Plant interfacing box:
Four plant interfacing boxes are provided, each of them placed close to the plant section it controls (UHT, aseptic tank, cip, mix) The interfacing box contains all the electro-pneumatic converters for valves control and also the terminal boards for the transducers. All these interfacing boxes are
connected to the general control board by means of multi-polar cable.

Auto/man stations (manual backup
Every item which is automatically controlled by the process computer can be started manually independently from the controls of the computer itself.
the forcing can be performed trough a switch after the autorisation is given
by a general key selector which, if disconnected, prevents the action of the
It has to be noticed that for the pneumatic items (on - off and
valves) we provide two manual safety levels; the first one is electrical
with possibility of direct control from the panel, the second one is totally
pneumatic (including the adjustment of the modulation valves) and it can be
performed in field by means of controls, key-locked, placed int the
pheripheral boxes. The manual back-up on the analogic adjustment rings takes
place by Auto(Man and Man/Auto with bumpless transition of each user in such
a way as to avoid any adjustment unbalance during the transition period. The
manual back-up is designed in such a way as to give alarms in case of
incopatible conditions even if computer unit is disconnects or used as a
simple observer. This will alert the operator of the wrong manual input.

Power section:
The panel is manufactured in carbon steel epoxy painted as per C Standards
In the panel purposely made for this section in order to avoid the
possibility of interferences with the computer there are placed the controls
of the motors. Each control is equipped with its contactor and protection
device of magneto-thermal type (acting as maximum load relay) . An aux.
Contact gives the signal of protection's tripping to the computer
performs the possible emergency procedures and gives alarm) and to the
mimic panel (which informs about the anomaly trough the colour of the LED
referred to the motor) . The same cabinet also contains the transformer for
feeding the aux. Services at 24 V and the rectifier in DC, the main
volt-meter and ammeter, and the plant main switch.

Plant interfacing boxes
Boxes in water-proof material complete wit key-locking.
Plant interfaces
Electric valves for converting the electrical signal coming pneumatically
>from the computer for the control of the process valves. They are complete
with manual control; 2.3 mm air-trough section to allow a quick reply; low
absorbtion for direct control from the computer. Electro-pneumatic
converters for converting the electric signal (analogue) coming
pneumatically (3 - 15 psi) from the computer for the control of the
modulation valves.

Pneumatic manual control:
Integrated unit for the direct pneumatic control of the modulation valves
including auto/man selector, variator and gauge.
