Contributing to productivity and quality improvement
Yokota Manufacturing Co., Ltd.
Defoaming/Degassing Pump ASP Type


Promoting itself as a company finding solutions to water and liquid handling problems, YOKOTA manufacturers and sells pumps and valves, and holds more than 100 patents. The "YOKOTA Defoaming/Degassing Pump ASP type" is a pump that was developed by applying the self-priming pump technology accumulated over many years and it can transfer water only after separating and discharging the air from the water.

In combination with an interlocked vacuum pump, it can instantly and continuously discharge wasteful bubbles and gas occurring when blending and agitating liquid food products. By equipping self-priming and pressurization functions, the conventional notions that food product defoaming/degassing requires expensive and large equipment have been overturned. In addition to its ability to manage everything from pumping to agitation, defoaming/degassing, and pressure feed as a single unit, the compact 300 mm wide and 800 mm long design enables its installation with almost no changes to an existing processing line, making it all the more attractive. What's more, because the pump has a minimal number of parts and a simple structure, maintenance and disassembly, and cleaning are easy.

The intended use is for defoaming/degassing processing at each stage in the manufacturing process such as the boiling, maceration, extraction, oil pressing, agitation, fermentation, and preservation, and defoaming processing and transfer prior to bottling of liquid food and dairy products, and it targets various products from high-fluidity liquids to high-viscosity liquids, and even to near-solid products such as miso paste. In addition, because it mechanically defoams and degasses and there is no need for the use of food additives such as defoaming agents, such indications on packaging are also unnecessary, which not only contributes to improved productivity and quality, but realizes improved safety and assurance, and reduced cost.

Contribution to improved productivity
President Mario Miura

The "YOKOTA Defoaming/Degassing Pump ASP type" applies the company's original self-priming pump technology and can continuously extract bubbles and gas in liquids.

Defoaming-Degassing Pump "ASP Type"
Yokota Manufacturing Co.

The Defoaming-Degassing Pump "ASP type" is equipment designed to continuously remove bubbles and air from liquid with the capability of reducing the oxygen in liquid (water) to 1/8 instantaneously. Moreover, with a volume of approximately 1/74, the pump provides space savings incomparable to equipment of the past. This has been a big plus for food product manufacturers looking to introduce this type of equipment, and Yokota has a strong sales performance throughout the food industry to show for it.
From its start, Yokota has been the top manufacturer of the "Enhanced Self-Priming Centrifugal Pump", a pump which conveys liquid mixed with bubbles and air. The Defoaming-Degassing Pump, developed utilizing Yokota original technology, focused on the preservation of food freshness by completely removing oxygen in the liquid (food product), and preventing oxidation and decay.
The main technological feature of the pump is its instantaneous and continuous separation of bubbles and gas in liquids using centrifugal force. The separated bubbles and gas are then extracted via strong suction from a vacuum pump. And a further advantage is obtained from the homogenization and particle refinement of the liquid by simultaneously performing agitation using the rotation of impeller blades. Moreover, equipped with both self-priming and pressurization functions, which in the past required a number of different components, the whole process can be performed using just one pump.

"Challenge"

A degassing pump that preserves the freshness of beverages
Yokota Manufacturing Co. (Naka-ku, Hiroshima City)

This special pump, which preserves the freshness of beverages, is attracting the attention of major food manufacturers across the country. A mid-sized pump manufacturer, Yokota Manufacturing Co., developed this "degassing/defoaming pump" in 2002. A transformation of the conventional perception of the liquid pumping function is brought about based on Yokota-developed original technology. This new technology addresses new needs in the food sector such as the removal of gas mixed in liquid to prevent oxidation and decay.

Removing oxygen prevents decay

"Is this possible with such small equipment...?" The clients had their eyes fixed on a pump approximately 1 meter wide. The demonstration was held at a prospective food manufacturer looking into degassing/defoaming pumps. A show of surprise appeared on the clients' faces when they saw that the air in the beverage had decreased rapidly after the beverage was pumped.
The food manufacturer's attention was drawn to this pump because it prevents oxidation and decay by removing the oxygen in soft-drinks or milk, preserving their freshness. The corporate director and manager of the Sales Division, Masayuki Akiyama (63), who was a leader in the pump's development commented, "The increasing concerns of consumers in food safety have been the push for this". There are other advantages such as the maintenance of firmness during cooking, or accurate measurement during bottling without any foam.

news Degassing defoaming

The Chugoku Shimbun

Reduction to approximately 1/8

Here's how it works. Liquid is transformed into a thin layer by the impeller installed inside the cylindrical pump rotating at high speed. The addition of vacuum pump suctioning draws the gas effectively due to the pressure difference with the liquid, reducing the oxygen in the liquid (water) to approximately 1/8.
Normally, in food processing plants, liquid is transferred to large tanks where the gas is discharged under a vacuum to remove the gas from the liquid. The disadvantages of this conventional equipment are that it is stationary, expensive; costing some 10 million yen or more, has an irregular degassing rate, and that it cannot be used for high viscosity liquids.

Perceptional change supported by original technology

The degassing/defoaming pump discharges gas effectively while moving the liquid using the pump. It is characterized by the fact that it can process high viscosity liquids, and it can be used for wide variety of food products. Moreover, it can be relocated easily, and it is inexpensive, costing approximately 10 million yen. Business operations have improved over the past year and the pump has been delivered to 6 food manufacturers. Yokota continues to receive inquiries from companies, to date about 20, which is a better-than-expected level of response.
The cornerstone of Yokota's development is based on 50 years of their originally developed technology. Their technological forte is the self-priming pump which can even pump gas-mixed water. A common pump cannot pump water if gas is mixed in it, however, Yokota's self-priming type pump can pump water together with gas because it separates the water and gas by the rotation of an impeller in the pump. The first such pump was developed in 1952. The technology used for pumping out ground water from coal mines was unexpectedly transformed for use in the food sector.
The patented technologies on the pumps and valves exceed 100. This is an exceptional amount of technology for a manufacturer with just over 100 employees (Chugoku Bureau of Economy, Trade and Industry). In recent years, they have acquired top market share in pumps that recirculate seawater at large aquariums by using strong, special stainless steel that is resistant to corrosion, making a strong showing in this special sector. "Our basic technologies have been applied to pump materials and structures" said a confident Fumio Nishi, the manager of R&D.

Needs are the turning point

Customer demand is also the watershed to development. The degassing/defoaming pump, developed in 2000, is equipment originally designed to pump water into water storage tanks in condominium buildings and degas it to prevent corrosion. However, there was very little customer response to this technology. At that point in time, Yokota had not considered applying the technology to the food sector. Then, an inquiry from a food manufacturer asked Yokota if degassing technology could be applied to beverages. This was the turning point. "A good product is not always produced only through technical capability. There is a point when the technology connects with the market needs." Something Yokota's corporate director Akiyama became keenly aware of.
