Yokota Manufacturing Co.
Small-size Defoaming pump introduced
Contributes to low volume production, test-production and research
Yokota Manufacturing Co. (Pres. Hiroshi Yokota, Hiroshima-city, Hiroshima
pref.), developer and producer of hydraulic equipment such as pumps and
valves, has increased its "ASP Type" Defoaming-Degassing pump
series which have been highly evaluated by the food industry. The newly
added and released version is a small-size "ASP-0115" pump compatible
with low-volume production lines, research, and test-production. The newly
released pump can process 10 liters of normal water per minute at normal
temperature. The ASP type series performs continuous defoaming and degassing
by installing it to the lines. Moreover, the series has a lot of merit
in terms of quality and energy aspects because the settling time, which
is required for liquid stabilization tanks, is not necessary.
Four types of Yokota Defoaming pumps are available and the processing performance
of each type is 10, 35, 60, and 90 liters per minute. They also meet sanitation
specifications by equipping legs to establish a clearance with the floor.
Defoaming of materials with a wide range of viscosity is possible, such
as low-viscosity beverages to high-viscosity jam, and even with paste-like
material such as bean paste (miso). As a result of their in-company tests,
the ASP type pump was able to deform laundry detergent, which foams easily
and is difficult to defoam, at a rate of 67 to 72%.
By defoaming material before charging it to containers, the amount of oxygen
in the product can be restricted, thus the prevention of product deterioration
due to oxidization is expected. This also leads to improvement in yield
ratios because variation in the charge amount is reduced and it can be
maintained constant. An increasing number of manufacturers are considering
and adopting defoaming pumps for thin-layer products such as chocolate
coating and edible film because if such products contain bubbles they must
be sorted out and rejected causing waste problems. Yokota is planning to
extend its business to a wide range of industry by presenting quality improvements
using defoaming capabilities customized to each user's products and processes.
