よくある質問

This page summarizes frequently asked questions from our customers about Kurita’s fully automatic filter presses, manual filter presses, squeezers, fine mills and other products as well as Kurita’s maintenance and service activities about these products. If a problem still persists after execution of the suggested remedies below, contact through relevant contact points.

電話やメールのやりとりで、フィルタープレスの見積もりが出来ますか?

Rough estimation may be possible based on our vast collection of data (data for about 5000 units so far delivered). However, physical properties of slurry can vary greatly depending on the nature of plant that generates the slurry. Therefore, Kurita Machinery subjects slurry sample to filtration test in the Kurita’s site, thereby Kurita will propose its filter press that best meets the slurry tested.

フィルタープレスは、どんなところで使用されていますか?実績はどうですか?

The scope of applications of our filter presses is much large, and includes production and sewage treatment lines in industrial fields including chemical industries, mining and manufacturing industries, pharmaceutical indutries, food processing industries, paper-pulp industries and electric-electronic industries. For information about the Kurita’s machines already delivered, see ****.

他の脱水機と異なるフィルタープレスの特徴はどんなものでしょうか?
  1. Because filter press is capable of withstanding higher pressure, the moisture content of resultant cake is lower, helping realize volume reduction of waste from production line.
  2. Extremely clean filtrate is obtained, and nearly 100% of solid matter can be recovered.
  3. Stable, reliable dewatering operation is realized.
フィルタープレスの主要部品の材質はどんものがありますか?

One outstanding advantage of our custom-building system is our ability to design and fabricate filter presses using materials that best suit the customers’ intended applications.

  1. Filter plate

    Material most commonly used for this purpose is polypropylene—a light-weight material highly resistant to chemicals and boasting good cost performance. Filter plate may be made of metal, and this type is used to process high-temperature slurry as well as oil.

  2. Filter cloth

    Three materials are most commonly used—polypropylene, nylon and Teflon. Compared with the two other materials, polypropylene is more wear-resistant and less expensive. Nylon boasts greater mechanical strength and wear resistance: however, it is vulnerable to acid. Teflon can be used to a maximum operating temperature of approximately 110C: however, it is vulnerable to alkali.

  3. Expression membrane

    Most common material used for expression membrane is natural rubber. Resin membrane is also available and can be used to process any slurry material.

フィルタープレスでケーキを洗浄することが出来ますか?

Of course, possible. Rinsing of cake with a filter press aiming at desalination and reduction in dielectric constant boasts higher efficiency with smaller water consumption, compared with other filtration-dewatering machine types. Rinsing of cake can be categorized into two types—straight rinsing and back rinsing. Better rinsing system is selected on the basis of physical properties of slurry.
We are afraid that filter cloth can get torn prematurely.

ろ布がすぐ破損するのでは

We adopt a unique system where only a minimum load acts on the filter cloth proper.

ろ布がすぐ目詰まりするのでは

Through repeated filtration tests, we have constructed a vast database about filtration (4000 press units, 5000 data sets); thereby, thanks to this database, we can select and offer our customer an optimal filter cloth that can positively capture particles in slurry but is less prone to clogging.
By rinsing the filter cloth with higher filter cloth rinsing pressure (4 MPa), progress of clogging of the filter cloth can be retarded.
We offer a special service (cost payable by the customer) to clean heavily clogged filter cloth by rinsing with acid.
An optional mechanism-process can be built into the machine that allows the installed filter cloth to be rinsed with acid within the machine.

スクイザーを導入時、1日の生産量は?

One model 150 squeezer unit (KM73-1S4BV-150) is capable of producing 400 kg of raw bean jam per hour. This means daily output of 1,600 kg (including 4 hours of dewatering).

生餡の含水率は?

We believe the moisture content in raw bean jam you are currently producing falls in a range of 61% to 63%. Our squeezer is capable of adjustment of moisture content in a range of 58% to 65% (the moisture content can vary depending on the operating conditions).

スクイザーの清掃時間は?

Time needed for cleaning auto press will take 1 hour or longer. Rinsing of squeezer will be complete in about 20 minutes.

ランニングコストはどうですか?

Its electricity consumption is relatively low: about 1/3 as much as that of vacuum dewatering machine. Other conditions can vary depending on the type of slurry being processed. Contact Kurita Machinery for technical assistance.

清潔に保つ事は出来ますか?

The machine is solely made of stainless steel and is buff finished. Thus, user can reliably control microbial count.

原材料の性質や生産量の変化に対応出来ますか?

The machine can be readily adjusted to a new operation mode since it is capable of more than 30 compressed air pressure settings and is fine-controlled by electronic controller.

ベルトプレスは大量の洗浄水が必要では?

Filtrate and cleaning water can be recycled. We offer an optional washing water recycling machine.

脱水ケーキの含水率を出来る限り下げたいのですが?

High-pressure type belt press can reduce moisture content by additional 2 to 4%, helping greatly reduce the volume of cake.

他社のベルトプレスとの違いは?

Kurita’s machine is simple and easy-to-maintain. Its frame and components in contact with liquid are made of 304 stainless steel, and the machine can withstand extended use. We are making special efforts in procuring materials and designing the machine to lower the price of machine.

ベルトプレスの得意な分野は?

Belt press is suitable for treatment of various industrial wastewaters, in particular wastewater treatment containing organic sludge.

ランニングコストはどうですか?

Its electricity consumption is relatively low: about 1/3 as much as that of vacuum dewatering machine. Other conditions can vary depending on the type of slurry being processed. Contact Kurita Machinery for technical assistance.
