Milk powder manual charging process extraction and recycling

Mars Food Jiaxing Co.,Ltd., China June 2019

Application Category
Extraction of airborne dust
Suction Media
Milk Powder

1. To control airborne milk powder dust during manual charging 25kg bag into charging station thus to protect the operators.
2. To recycle the milk powder collected from Cyclone back to the charging station thus to reduce the waste and raw material cost.
3. Filter change on standard dust collector before was necessary 2 times per month. The filter life at full performance with new RUWAC system is minimum 6 months

Product Group
Dust Extractor DS 6
Silo Vacuum

1. To recycle the milk powder collected by the extraction system back to the charging station.
2. To extract airborne milk powder dust during manual charging 25kg bag process.
3. To improve the hygiene of the recycled milk powder

1. Previous used Italian Mix extractor was placed directly on top of the charging station to extract the airborne milk dust during charging process and then blown down the dust from its cartridge filters back to the charging station. This kind of simple extractor cannot meet the extraction, filtration and recycling requirement. It resulted with almost no air volume and poor extraction performance, frequently clogged filters (needs to be replaced every 2-3 days) , and possible contamination of recycled milk powder which has direct contact with the clogged filter.
2. It also caused long down time to fix the extractor and high dust concentration rate in the workroom.

A DS64000 Extractor, HGZ DN630 Cyclone and automatic discharging valve system with complete control and alarm functions to realize the dust extraction during charging process and automatic recycling of collected dust from Cyclone.

• DS64000 M Zone 22 Extractor System, 2.2kW 3-Phase Side Channel Blower, 24m2 Cartridge Filter Class M with automatic compressed air filter cleaning mechanism, Control System for monitoring & signaling sound & light alarm: main filter differential pressure, filter cleaning, and remote start/stop function.
• Food grade HGZ DN630 Cyclone and discharging system with high separation rate and automatic discharging valves.
• According to the test validation in Thailand during the project negotiation stage and also the project final validation test at Mars production line during commissioning, the separation rate of Cyclone is about 99%.

1. Automatic & continuous extraction and recycling of charging dust
2. Improving the recycling rate and hygiene
3. Reducing production down time
4. Substantially Improving air quality and protect the operators
5. Food grade extraction and recycling system
