Success through expanding the possibilities of pumps



The following is a summary of the article "Small market leading company", featured in the Nikkei Business magazine, Aug. 22, 2005 issue.


A pump that removes bubbles and gas from liquid food products has cornered the Japanese domestic market.
Yokota has discovered new markets while always aiming to develop products that have yet to make an appearance on the market.
Yokota develops its materials in-house and has expanded the capability of pumps into various market sectors.

Gas and bubbles dissolved in liquid are extremely troublesome for factories handling liquid food products. This is because the liquid inside the product charging devices clogs, and liquid measurement becomes inaccurate. Dissolved gas in milk or fruit juice promotes oxidation, resulting in degradation of freshness and flavor.

To avoid these negative effects, conventional defoaming/degassing devices have been available, however, the common defoaming/degassing method was to transfer liquid to large tanks and wait until the bubbles disappeared and gas dissipated naturally. Another method that saves defoaming/degassing time is by controlling the holding tank interior close to near-zero vacuum conditions to forcefully remove gasses dissolved in liquid, however, there is a limit to the time-savings.

Under these circumstances, a device that could perform continuous defoaming/degassing using a pump was released in 2000. The pump can perform at a rate of up to 4000 liters per hour, and this has undoubtedly attracted the attention of the food industry.

Creation of new markets through applied technologies

Yokota's market share in defoaming/degassing pumps for liquid food products

Yokota has been undergoing business negotiations with more than 100 companies, mainly food manufacturers, and has already delivered pumps to 10 companies.

Recently, Yokota has successively delivered pumps to aquariums that recirculate water in the water tanks. Half of the aquariums that have opened in recent years, such as the Okinawa Churaumi Aquarium in 2002, and the Oita Marine Palace Aquarium in 2004, have adopted Yokota products. One of the difficulties with aquariums is that seawater is one of the most difficult liquids for pumps to handle because it contains various substances besides salt and minerals. Enhanced pump performance is a prerequisite at aquariums where any number of precious fish and sea animals are raised. This added high performance at aquariums is a direct example of Yokota's development capability.

Yokota's position of continuing to produce products that have yet to make an appearance on the market remains unchanged.
Yokota is expected to produce even more new products, striving towards product development in the belief of the immense possibilities of pumps.
