Food Industry
Though you might not realise it, dry compressed air affects each and every manufacturing unit in food industry.
Use of Compressed Air Dryer in Food Industry
In food manufacturing units, generally following compressed air powered pneumatic machines are used:
- Pneumatic control and actuators
- Labeling machine
- Packing machines
- Pelleting machine
- Weighing equipment
- Conveying machine
Problems
A major problem in compressed air systems is the presence of water, dust particles, oil (oils particles are introduced by lubricated air compressors) and solid contaminants which can adversely affect air quality.
If the contaminated compressed air will be used through pneumatic tools and machines then there will be following problems:
- Malfunctioning of pneumatic tools and machines
- Sluggish and inconsistent operation of valves and cylinder
- Corrosion in pipelines, cylinder and other components
- Increase in downtime
- Increase in maintenance cost of pneumatic machines/tools/controls
- Freezing in exposed lines during cold weather
Moisture in compressed air also leads to problems like:
- Containers requires reliable clean-out and evacuation to meet stringent quality standards.
- Moisture and dust particles in air tight packs may spoil food.
- Presence of moisture and dust particles during spraying leads to unhygienic food.
- Presence of moisture and dust particles in baked food trays may spoil food.
The majority of food products are highly hygroscopic and tend to suffer physical, enzymatic, microbiological, and biochemical deterioration after coming in contact with moisture-laden compressed air.
Applications
Pneumatic machines
Spraying and coating
Conveying
Packing
Filling bottles
Solution
Remove water, dust particles, oil (lubricated air compressors introduce oil particles), and solid contaminants from compressed air.
The Delair Solution
Delair offers a wide range of refrigeration and absorption dryers that remove water/moisture from compressed air.
Delair Refrigeration Dryers
This dryer operates on the method of cooling the air to near freezing point to remove the moisture and reheating it to approximately 10°C below the incoming compressed air temperature at nominal conditions.
Delair Adsorption dryer
The dryer is based on the principle of heatless regeneration and the physical properties of the desiccant to adsorb and desorb water vapour. It uses the pressure swing principle/purge air to regenerate the desiccant bed.
Filters
Delair also offers Pre Filters and Oil Filters, which removes dust particles, oil particles and other types of solid contaminants present in dry air.
Frequently Asked Questions
1. Where is compressed air used in the steel industry?
Compressed air supports several steel manufacturing operations, including pneumatic tool powering, descaling and spray cooling, welding, pneumatic feeding of sheet stock, material conveying, and pneumatic control systems. Reliable compressed air for steel industry applications helps keep these processes operating consistently.
2. What problems can contaminated compressed air cause in steel manufacturing?
Water, dust, oil, and solid contaminants can cause pneumatic tools and machines to malfunction, make valves and cylinders operate inconsistently, and contribute to corrosion in pipelines and components. These issues can also increase downtime and maintenance costs.
3. What type of dryer is suitable for a steel plant compressed air system?
A refrigeration dryer for steel plant applications can remove moisture by cooling compressed air to near its freezing point and then reheating it. For applications requiring a lower dew point, adsorption dryers can provide additional moisture removal for Instrument air quality .
4. What air treatment solutions does Delair offer for steel mills?
Delair provides an air treatment solution for steel mill applications that includes refrigeration dryers, adsorption dryers, pre-filters, and oil filters. These systems help remove moisture, dust, oil, and solid contaminants, supporting cleaner and more reliable compressed air. Delair’s solutions can also support a dry air system for iron manufacturing where moisture control is important.
