Filling Machine for the
Because liquid soaps and detergents (and laundry softeners) are fairly thin
viscosity, they are capable of being filled on more than one type of filling
machine. The choice of filling machine would depend on what relative
advantage is more important: speed versus cost. The least expensive filling
machine that can package these liquid products is the overflow filling machine.
It is also the slowest producer but with great flexibility. A piston
filler is a fast producer at higher cost but with some disadvantage in
changeover time and fill size range. The servo pump filler can fill any size
container at fast rates but at high capital cost.

Filling Machine for Liquid Soap Products
Generally speaking, all liquid soaps and detergents are
very similar in viscosity with a range from about 1000 centipoise not exceeding
10000 centipoise. This viscosity range does make it suitable for use in an
Overflow Filling Machine but the product will run quite slowly on the upper end
of this range. This will require many fill nozzles and possibly more than one
pump to distribute the load and backpressure evenly. Therefore, smaller
producers of these products will enjoy a lower capital cost of equipment but
will find their output limited. As the viscosity of the soaps increase, the
number of nozzles will correspondingly increase and thereby increase the capital
cost up until the point that it is now at par with the cost per output of a
smaller piston filling machine. Foreign producers in smaller countries with
smaller markets find this machine very attractive for lower outputs. The
advantage of this machine is also its ability to fill nearly any size or shape
detergent container with no changeparts and fast changeovers.
be noted that many new producers think that mild steel construction of the
filling machine is acceptable for a non food grade product such as detergent. In
actuality, detergents are quite corrosive and therefore these machines must be
constructed of 304 stainless frame with 316L stainless fluid paths.
Filling Machine for Thick or Particulate Food Products
Food products that are thick like heavy
sauces and pastes or that have a high particulate content including large pieces
of meat or vegetables like chunky salsas, require a filling machine with the
necessary force and large enough fluid path to pass these products. A
thick paste simply will not pass through an overflow filling machine and 1"
pieces of tomato and onions will clog up overflow and gravity filling machine
nozzles immediately. Therefore, the piston filler is used widely to handle these
types of products. In fact, in the food filling business, it is probably the
most common filling machine wth an excellent cost to performance profile
although piston fillers are more costly than overflow fillers with similar
outputs. These type of filling machines are fairly fast producers with typical
outputs of 10 containers per minute per nozzle These machines can also be
configured with jacketed product hoppers to maintain hot fill temperatures as
well as rotary agitators to keep heavy particulates in proper suspension.
. It should be noted that while these machines are ideally suited to thick or
chunky food products they are not well suited to thin flowable products as
described in the Overflow Filling Machine description above. Although it is
possible to fill thin products in a typical food piston filler, the large fluid
path is prone to drips or leaks on thin products for the very same reason it is
ideally designed for thick and chunky products. This types of filling machines
are also very accurate providing a volumetric fill size that is precise to
greater than 1% of volume.
||Servo Pump Filling Machine
for Almost All Food Products!
The Servo Pump Filling Machine is an extremely flexible, easy to use and easy to
clean filling machine in a class of its own which can fill almost any food grade
product you can imagine. Because it can handle an extremely wide range of
viscosities and can pass particulates up to 3/4" diameter without chopping, it
can be used to fill Juices, salsas, jellys and jams, salad dressings , sauces
and some pastes. This filling machine shines because of its ease of
cleaning and it makes it very convenient for producers that have many different
flavors or products to produce in one day. These filling machines have been
successfully installed in USDA plants because of their cleanability. A computer
controlled pump dedicated to each filling nozzle allows for total programmatic
control of all filling parameters with unlimited fill sizes, high volumetric
accuracy and the ability to deliver almost any thick, thin, particulated or non
particulated sanitary product into almost any container. This type of filling
machine is considered a contract packager's dream.
As you would surmise, all of this flexibility comes at a high capital
cost. Each servo controlled pump/nozzle combination typically costs over
$10,000 per nozzle. However, this machine pays for itself where the
producer has many food products to produce in small batches; the short cleaning
time and nearly instantaneous setup time of operating parameters makes it
possible for the producer to fill many unrelated product batches in the same day
and be very responsive to his or her customers.
