Dust problem and solution
2022-12-21

ABOUT POWDER

Powder comes from:

  1. From granule
  2. From freeze dry
  3. From spray dry
  4. From others

The particle size of powder produced through the above way is not stable, they will have some bigger and some smaller particle. When filling, the smaller and light particle will suspend following the air flow and/or rebound when contacting any surface.

ABOUT DUST

We cannot prevent or stop the dust because it is a physical phenomena of nature but the dust is influential to the packaging.

 

Normally speaking, the influence to the packaging is:

  1. It is not easy to keep clean of the equipment.
  2. The sealing quality will be not stable during production.
  3. If the bearing is covered by dust, the parts life will be short.
  4. Filling area is dusty and not easy to clean.

SOLUTION 1

We have dust collection nozzle to collect the dust in filling area.

SOLUTION 2

We have another dust collection nozzle in static stretching area to collect the dust when bag closing.

 

SOLUTION 3

The material of frontal contact parts is stainless steel 304/316, non-contact parts is also using SUS304 and 5/6 aluminum, both of them are easy clean and no rusty problem in the future. The moving parts which needs lubrication is behind the machine far away from dust.

SOLUTION 4

Our HFFS machine is equipped with safety door, machine auto-stop when door opens. It is capable with CE standard. The dust will not able to fly outside to effect the clean room.

HFFS V.S. VFFS

FORMAT NO FORMING TUBE NEED FORMING TUBE
FILLING DISTANCE SHORT、10-20cm LONG、60-80cm
REBOUND SMALL BIG
DUSTY LIGHT HEAVY
CONTROLABILITY EASY CONTROL DIFFICULT
COLLECTION YES WE CAN COLLECT NO COLLECTION
SEALING GOOD NOT STABLE
FILLING ACCURACY GOOD NOT STABLE
MARKET HIGHER LOWER

CUSTOMIZED

Different powder, different particle size, different volume of dust, thus, we will make customized parts to help solve dusty problem to get:

  1. Stable production speed
  2. High good product ratio
  3. Excellent sealing quality
  4. Beautiful bag looking
