2021.10.12 [No.29] Satake Wet Classifier

Satake iClassifier

【Company A】Significant Increase in Production Efficiency

  • Amid the rapid increase in demand for their main products, the classification process was a bottleneck in aiming to increase production. Thus the new classification technologies were being sought.
  • The raw material of the product was single-micron-size monodisperse particle. The small amount of fine powder and coarse powder in the material were removed by classification. The existing process was carried out in a gravity settling tank.

  • [Productivity improvement by introducing iClassifier]
  • In the existing process, it took 3 days (3d × 8hrs = 24hrs) to classify 1.5 kg of particles per batch; however,
  • With the introduction of the iClassifier, the process was shortened to "6 hours". (75% reduction)
  • 【Company B】Make the impossible possible (Key for homogenization of material form)

  • For the main products, they were required to further reduce the mix rate of coarse particles by the customer.
  • In the manufacturing process of the product, the raw material goes through the dry classification to remove coarse particle, but at a very small rate, coarse particles were still tampered.
  • They tried to consider removal with various dry classifiers, but could not meet the required quality.

  • [Realization of high-precision coarse grain removal by introducing iClassifier]
  • The introduction of iClassifier and wet-classification has made it possible to remove trace amounts of coarse particles that could not be removed by existing equipment.
  • The processing speed is relatively lower than that of dry equipment, thus Satake is continuing to consider equipment scale-up.

  • 2016.10.10 [No.28] Automatic bagging machine eliminates dust in the room and decrease the unnecessary overfill in the bag at the same time.

    NLI Chicago

    ===> 50% reduction of unnecessary overfill into a bag (40-50 lbs) is achieved.
    <Specifications of NLI Automatic Bagging Machine (FG-R-8)>
    Machine speed: 480 bags/hr
    Weight per bag: 50 lbs
    Accuracy: 1/1000 (+-0.8 ounce)
    Bag type: craft paper (double) + inner poly
    Auger filler: Yamato auger filler (2 sets - large and small)

    2016.10.01 [No.27] High Temperature spray dryer saved investment cost - compared with a conventional furnace/kiln with spraying system

    Fujisaki Electric
    "HIGH TEMPERATURE" type MMSD laboratory spray dryer MDL-015(C)M-H
    1) Place: Metal ion aqueous solution plant
    2) What is installed?: 1 set of spray dryer MDL-015CM-H
    3) Before: Old rotary kiln with spray system
    4) After: Slurry is directly spray dried and preheated at 600 degree C (1.112 degree F) with simple system. By drying at high temperature, dry spherical powder is pre-furnaced before the next decomposition or reaction process.
    << Features of MDL-015(C)M-H >>
    1) Evaporation speed is up to 1kg/hr(2.2 lbs/hr, exit temperature is 300 degree C - 572 degree F).
    2) Single micron order - spherical powder can be produced using 4 fluid nozzle from slurry.

    2016.06.01 [No.26] 30/35kw & 90/105kw (120,000 & 360,000 BTU/hr) Adsorption Heat Pump (AdHP) chiller are now in product line

    30kw & 90kw AdHP chiller LTC30-ePlus & LTC90-ePlus
    1) Place: Data Center in Germany
    2) What is installed?: 1 set of AdHP chiller LTC90-ePlus (thermal driven chiller utilizing hot water) and 2 sets of gas 50kw CHP (Combined Heat & Power)
    3) Before: Freon compressor HVAC system was consuming a lot of electricity at Data Center
    4) After: No grid electricity is required any more. CHP can supply required power and the generated hot water is used by AdHP chiller, which can produce chilled water (used for HVAC at Data center and direct cooling of server). No need to install complex hot water/chilled water/recooling water piping for multiple units of AdHP chiller.

    2016.05.03 [No.25] Rope twisting type Iris Valve reduces automatic valve cost
    Mitsumi Iris Valve "CHOKE VALVE" (manual-left and automatic valve-right)
    1) Place: Food powder processing plant
    2) What is installed?: Mitsumi Iris Valve with air cylinder
    3) Before: Motor drive Iris valve was used for 180-degree motion
    4) After : MITSUMI Iris Valve opens/closes valve by 90-degree motion by air cylinder

    2015.05.01 [No.24] Double Scrubber to stop dust creation from dust collector
    ACO Wet Scrubber - Double Scrubber
    1) Place: Glass manufacturing factory - after glass melter
    2) What is installed?: ACO Double Scrubber DWS-120H (120 m3/min @ 70 degreeC, 2.5kPa)
    3) Before: Dust collector was used. Precipitated material builds up on membrane filters and quickly clogs them. Gas flow rate sometimes drops down because of this and makes the room dusty.
    4) After : Precipitated material is fully collected in the scrubber. No maintenance is required. No dust in the room.

    2014.05.06 [No.23] Ferrule band type air knocker is available for sanitary purpose
