Defoaming/Degassing while maintaining quality
Yokota Manufacturing Co., Ltd.
Pump for liquid food products
[Hiroshima] Yokota Manufacturing Co., Ltd. (Mario Miura, President. Naka-ku,
Hiroshima, 082-241-8674), began sales of its DP type pump which can defoam/degas
while maintaining the quality of liquid food products. Prices range from
about 3.5 million yen (tax excluded) for the general-purpose type with
a bore of 15 millimeters, and from about 7 million yen (tax excluded) for
the sanitary specification type. To respond to a variety of needs, plans
are to add pump types with bores of 30, 50, 60, and 80 millimeters in the
By the added improvements to the shape of the impeller, the DP type can
defoam/degas at nearly half the rotation speed of the current "ASP
type" pump of the company. As a result, the problem of liquid alterations
due to sheer and increases in temperature has been resolved which enables
defoaming/degassing while maintaining the quality of the food products
such as the texture.
The company's principle behind the defoaming/degassing is to flow liquid
into the depressurized pump and separate the gas from the liquid by depressurization.
The gas is accumulated in the central area of the pump by the effects of
centrifugal force by the impeller which rotates inside the pump, and the
gas is then discharged by a vacuum pump. The company has a sales record
of over 150 pumps concentrating mainly on the food industry.
