Containers: The BOST-PLC fillers are capable of filling containers from 100 ml to 5 liters (4 oz. To 5 qt.). They will fill most rigid containers that have a smooth neck opening of at least 1 cm (1/2") and no more than 50mm (2").
Products: Liquids with viscosities to 200 cps may be filled on standard models. More viscous products may be filled wtih the addition of a pressure or vacuum fill system. Standard metal product contact parts are 304 stainless steel, product contact parts in 316 stainless steel and PVC are available. Standard hoses are PVC.
Operation: The BOST-PLC model fillers are controlled by an industrial PLC to provide
a completely automatic operation.
A worker loads containers onto the infeed conveyor of the machine and they
are moved to the filling area. The sequence begins withe the entry gate open and the stop
gate closed. The containers are counted as they move past the entry gate. When the
correct number of containers are below the filling nozzles, the entry gate closes and
the conveyor stops.
The nozzles automatically descend and begin filling. While
the containers fill, the exit gate automatically opens. When the containers
are filled, and overflow has started, the nozzles automatically close and rise. The conveyor automatically begins
to move.
The filled containers are counted and the exit gate closes to hold the empty
containers below the nozzles. When the correct number of empty containers have
entered the filling area, the entry gate closes and the next filling operation begins
automatically.
| CONTAINER- | 500 ml | 1 Liter | 2 liter | 4 liter |
|---|---|---|---|---|
| MACHINE | Pint | Quart | 1/2 Gallon | Gallon |
| BOST-CT-4 | 1200 | 900 | 600 | 350 |
| BOST-CT-6 | 1800 | 1350 | 900 | 525 |

Filling speeds are based on filling water with a gravity model, all container
openings are 25 mm.
*Based on filling round containers. Rectangular containers may have dimensions
that do not permit 12 bottles on the filling platform. In this case, only 10
nozzles would be used and the speed would be at the BOST-10.
Accuracy: The machine will fill to a consistent level. If the containers are regularly shaped, the machine will fill to an accuracy of ± 0.5% of target.
Installation: The machine is shipped with the tank unmounted to reduce shipping volume. The tank is bolted to the frame. The machine is installed on a table (supplied by others). The product supply is attached to the side of the tank. The tank level switch is connected to the product supply
Supply of Product: The product must be supplied to the tank by
either a pump or a gravity supply. The tank includes a float with an
electric or pneumatic level switch to control the tank level.
If the tank is supplied by a pump, the switch would be connected
to the pump motor. The pump would go on when the level switch is
depressed (low level) and go off when the tank is refilled.
If the tank is supplied by gravity from a larger elevated tank, the
switch can be electric or pneumatic and open and close the valve
on the larger tank.
If the machine is supplied as a pressure filler or gravity filler, the tank would not be included, but a pressure or vacuum system would be included.
Overflow: With each fill, there is a small amount of product that will overflow. The overflow is normally captured in a container (supplied by purchaser) placed behind the table on which the machine is installed and the collected product returned to the tank when the collection container becomes filled. An automatic system for the return of the overflow of product is available.
Change of Container: Containers are placed in the guide and the rails are
adjusted for width. The nozzle position is adjusted horizontally and
vertically so that the nozzles are positioned correctly above the
container openings when they are in line on the filling platform.
The micrometer nozzle adjustment permits the nozzles to be adjusted
so that the correct level is maintained in the containers. Normal
change time is 20 minutes.
Fill Timer: The machine is equipped with an adjustable timer to control the
time of fill and limit the overflow. The timer is set so that the fill time is
slightly longer than than the necessary fill time and it is adjustable to 0.01 second
increments. The timer would allow approximately 0.05 seconds of filling greater than the
time required for a fill to be sure that the level is reached on all nozzles and
accuracy is maintained.
Change of Product: The tank is rinsed and test containers are filled to drain and flush the system.
Maintenance: The machines are designed to provide the user with a long service life. Critical parts are stainless steel and USDA approved materials are used to permit filling of food products. No special tools are necessary for adjustments or maintenance.
Utilites Required:
Electric: The standard electrical service is 115 v/60 hz/1 phase. It may be
supplied in other configurations.
Pneumatic: The pneumatic system requires less than 25 l/min at 6 bar.
Personnel Required: None.
OPTIONS:
Foam Reduction Nozzles: Recommended for products that foam
when poured. These nozzles reduce the foam and the amount
of overflow.
316 Stainless Steel metal contact parts or PVC contact parts replacing
304 stainless steel metal
contact parts: This is for applications which require greater
corrosion resistance.
Vacuum or Pressure Operation: For more viscous products,
gravity filling may be unacceptably slow. In these cases, the
filling system may be supplied in either a vacuum or pressure system.
A vacuum system includes a small vacuum pump on the overflow lines of the
filler. This will cause a more rapid flow from the nozzles because
of the low pressure in the container. A pressure system includes a
pump on the product line and eliminates the tank on the machine. The
suitability of the gravity, vacuum and pressure systems depend on the
product characteristics.
Automatic Drip Cup: The automatic drip cup will keep the containers clean
if there are drips from the nozzle.
Automatic Overflow Return System: This automatically returns product which
has overflowed to the supply tank.
Rotary Feed Table: A rotary feed table will aid the placement of the containers
on the infeed section of the conveyor to make the container loading more efficient.
