Unique defoaming equipment capable of continuous suction, defoaming and
transfer of liquid containing gas bubbles.
It is often the case that gas bubbles are generated in the processing of
liquids such as liquid foods, beverages and chemicals, and the bubbles
cause the following difficulties:
|
|
Measurement of liquid quantity becomes inaccurate, and flow rate control
becomes difficult.
|
|
|
Troublesome and costly removal of overflowing bubbles.
|
|
|
Bubbles cause difficulty in sending liquid to the next process.
|
|
|
Bubbles overflow during packaging, causing deterioration in packaging efficiency.
|
These problems have been commonly dealt with by giving time for the bubbles
to settle down. However, this creates new problems due to the amount of
time required for bubbles to settle down, causing a loss in processing
time, and the necessity of installing a large tank for stabilization of
liquid, which increases processing costs.
The Defoaming Pump, Defoaming Equipment UPSA type can clearly solve all
these problems.
The pump, with an interlocked vacuum pump, produces a stable supply of
defoamed liquid by continuously separating and discharging gas bubbles
from liquid at surprising efficiency.
This pump (defoaming equipment) defoams liquid mechanically without using
any chemical additive. Therefore it is safe, does not cause contamination,
and greatly reduces maintenance costs.
Principle of defoaming (PAT.)
|
|
|
|
When pumping liquid containing gas bubbles flows into the inducer, liquid
and gas are initially separated by rotation of the inducer. The mist-like
gas-liquid mixture accumulates in the central area of the casing.
|
|
|
The gas-liquid mixture is transferred through the main impeller to the
separating impeller. The remaining liquid in the mixture is further separated
and the gas is drawn out by the vacuum pump.
|
|
|
The liquid separated by the separating impeller returns to the intake of
the inducer by centrifugal force.
|
|
|
Minute gas bubbles remaining in the liquid are confined to the central
area of the casing by the pressure difference generated by the main impeller
and transferred to the separating impeller, by which defoaming efficiency
is further enhanced.

|
Surprising defoaming efficiency!

Moreover, YOKOTA Defoaming Equipment enables remarkable cost reduction
in the processing of various foaming liquids.
|
|
|
No clogging problems like that with membrane type equipment, no troublesome
maintenance required, and the pumps easily meet sanitary specifications.
|
|
|
Time required to eliminate bubbles has been shortened, making it unnecessary
to install a large tank for stabilization of liquid.
|
|
|
The stirring operation of the built-in impeller simultaneously provides
favorable results such as liquid homogenization and reduced particle size.
|
|
|
With the self-priming and pressurized discharge capabilities, all processes
including suction, stirring, defoaming and transfer of liquid are achieved
in this single, compact pump, unlike conventional methods which require
installation of several components.
|
Use of YOKOTA Defoaming Equipment greatly reduces costs of liquid processing.
|
Equipment suitable for defoaming relatively small amounts of liquid and
equipment for defoaming with sanitary specifications are also available.
