>Selection & Dimensions

This defoaming/degassing pump, with an interlocked vacuum pump, extracts and discharges even dissolved gas in liquid with surprising efficiency.

Degasses liquid mechanically without using any chemical additive such as hydrazine. Therefore it is safe, does not cause contamination, and greatly reduces maintenance costs.
We also manufacture pumps that meet sanitary specifications.

Principle of degassing (PAT.)
DP
type

When pumping liquid flows through the orifice into the intake part of the pump, the dissolved gas in the liquid is separated from the liquid by decompression, and the generated gas-liquid mixture is fed to the inducer.

The liquid in the gas-liquid mixture is pushed against the periphery and stratified by rotation of the inducer, and the gas accumulates in the central area of the casing at the same time.

The gas remaining in the liquid is further separated from the liquid, as such liquid stratum is broadly exposed to high vacuum.

The gas is then drawn out by the vacuum pump through the impeller.

Any remaining liquid in the gas drawn out by the vacuum pump is separated by the impeller, and returned to the intake side of the inducer.

Principle of Defoaming/Degassing Pump



Surprising degassing efficiency!
Surprising degassing efficiency, ASP type, DP type
The above is a typical example of defoaming/degassing pump's degassing performance.
Please contact us for more information.
 

The outstanding degassing power is evident by the reduction of dissolved oxygen from a near 8mg/L at the intake side (raw water at 20 degree C) to 0.5mg/L or less at the outlet side.

We are holding an "Online Exhibition" where you can experience the same kind of tour as a real exhibition on the web.
Many videos showing actual examples of operation for processing various liquids and evaluation methods for defoaming and degassing results are available.
(> "Online Exhibition" page)

Continuous defoaming/degassing can be done easily and at low cost even for food and beverage processing!
YOKOTA defoaming/degassing technology is high-profile new technology that has been featured in news articles.

19th Nissyoku Excellent Food Machinery/Material Award in the machinery category.The "YOKOTA Defoaming/Degassing Pump ASP type" received the 19th Nissyoku Excellent Food Machinery/Material Award in the machinery category.

The 19th Nissyoku Excellent Food Machinery/Material Award ceremony, established by the Japan Food Journal Co. Ltd., was held September 9th, 2016 in the Dai-ichi Hotel, Tokyo (Tokyo Minato Ward, Shinbashi) where the company's Defoaming/Degassing Pump ASP Type received the award in the machinery category.

The Nissyoku Excellent Food Machinery/Material Award was established by the Japan Food Journal Co. Ltd., in 1998, aimed at the development of machinery and robots supporting the food industry and materials industry, and to reward and show appreciation for their contributions, with this year being the 19th time that the award was presented. The target products include all machinery/robots, intermediate materials/sub-intermediate materials, and the software utilized by them, which are useful to the quality improvement of food products and support the food industry, such as food product-related machinery/robots/apparatus and their software, intermediate materials/sub-intermediate materials for packaging containers, food additives, essence, food ingredients, and functional raw materials. The awards are decided by a selection committee made up of representatives in various food industries and academics who discuss with and consult each other in reaching decisions.

The company's "Defoaming/Degassing Pump ASP Type" enables the instant and continuous removal of wasteful foam, bubbles and gas occurring in the food product manufacturing process, and it has been credited with contributing to the improvement of product quality and production efficiency, which led to it winning the 19th Nissyoku Excellent Food Machinery/Material Award in the machinery category.

Applications

Defoaming/degassing treatment of liquid foods and dairy products in each production process such as boiling, immersion, extraction, oil extraction, mixing, fermentation, and preservation; Defoaming treatment and transfer of liquid products before bottling
<Application example>
Milk, soy milk, fruit juice, vegetable juice, vegetable paste, mustard, egg mixture, gelatin, milk drink, ketchup, various juices, tea, fermented liquid, yeast liquid, cream, jelly, vinegar, soy sauce, various seasonings, other

Supply of degassed water for high quality (high transparency) ice making

Prevention of malfunction of various measuring instruments (flow meter, density meter, other)

Defoaming/degassing and transfer of various raw material liquids
<Application example>
Various coating liquids, water-based paints, UV curable paints, urethane-based paints, plating liquids, pigments, adhesives, chemical raw materials, grinding oil, light oil, water-based polymers, insulating oil, desulfurization liquid, rinse, detergent, gel, calcium carbonate, other

Outstanding performance is also demonstrated in applications such as extraction from sealed tanks (vacuum tanks), and suction and transfer of liquid containing large amounts of gas, foam and bubbles.




YOKOTA's proposal: Troubled with stubborn foam and bubbles ? ........ The ASP type pump is the solution to the problem.

What if the ASP type pump, originally designed for degassing, is applied to defoaming ?
As expected, the defoaming tests have proven excellent defoaming performance as indicated below.

Moreover, YOKOTA Degassing 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 foam and 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 Degassing Equipment greatly reduces costs of liquid processing.
