Air Compressor
Clean air for every actuator
An industrial air compressor sized for cashew lines — the clean compressed-air supply for the peeling machine, the automatic vacuum packing line and the colour sorters.
The TTQ Air Compressor supplies the clean, dry compressed air that automatic cashew machines depend on — driving the air jets on peelers, the ejector nozzles on colour sorters, and part of the automatic vacuum packing line — shelling and cutting are mechanical and use none. Sized to the line’s air demand and fitted with drying and filtration for food-grade cleanliness, it is a foundational utility for any automated plant.

Sizing air around peeling, not around the whole line
Clean air supply
The shared pneumatic source for the machines that actually use air — peeling above all.
Drives the automation
Powers peeler jets, sorter ejectors and part of the vacuum packing line.
Dry & filtered
Food-grade drying and filtration keep oil and moisture off the product.
Sized to demand
Capacity is matched to the combined air draw of your machines.

Air compressors — models
Compressed air for pneumatic cutting, peeling and colour-sorting. Inverter models save energy; second-hand Japanese units offer lower entry cost.

The air compressor is the piece of equipment most often left off a quote and most often undersized. On a cashew line it does not power an optional accessory — the peeling machine physically cannot separate testa from kernel without it, and pneumatic conveying stops with it. Treat it as part of the peeler, not as a workshop tool.
Sizing against the peeling machine
| Driven equipment | Compressor rating | Approximate power |
|---|---|---|
| 1-head peeling machine | 30 HP | 22 kW |
| 2-head peeling machine | 50 HP | 37 kW |
| 3-head peeling machine | 75 HP | 56 kW |
| 4-head peeling machine | 100 HP | 75 kW |
Add any other pneumatic equipment running at the same time — conveying, ejection on a colour sorter, packing — before choosing a rating. Undersizing does not announce itself as a fault; it shows up as inconsistent peeling.
Rotary screw or reciprocating piston
Rotary screw
designed for continuous duty, quieter, steadier delivery, better efficiency over a full shift. Costs 30–40% more up front and is the right choice for a production line.
Reciprocating piston
cheaper, tolerant of intermittent use, but not intended to run all day. On a continuous line it wears fast and delivers less consistent pressure.
The practical rule
if the compressor will run more than a few hours at a stretch, buy screw. The initial saving on a piston unit is recovered by the electricity bill and the replacement cycle.
Air treatment is not optional
Dryer
compressed air carries moisture. On a food-contact stage that moisture lands on kernels, and it also degrades separation performance.
Filters
oil carry-over from the compressor is a contamination risk on a food product. Filtration is a food-safety control, not a nicety.
Receiver tank
smooths demand peaks so the compressor is not cycling constantly, which extends its life and steadies delivery pressure.
Distribution piping
sized for the flow and sloped for condensate drainage. Undersized piping produces a pressure drop that looks like an undersized compressor.
Budget the system
compressor, dryer, filters, receiver and piping together, not the compressor alone.
Keeping it running
- Drain condensate daily — water accumulates in the receiver and will otherwise travel down the line to the kernels.
- Change filters on schedule — a blocked filter causes a pressure drop that gets misdiagnosed as a compressor fault.
- Check for leaks — leaks are the largest avoidable energy cost on a compressed air system, and they are usually audible when the line is quiet.
- Monitor delivery pressure at the machine, not at the compressor. The difference between the two is the diagnosis.
- Ventilate the compressor room — intake air temperature affects both output and component life.
The compressor serves the peeling machine primarily, and often pneumatic conveying and colour-sorter ejection as well. Size it against total simultaneous demand — see peeling machine price, where the compressor requirement per head count is tabulated.
The process, drawn
What actually uses compressed air
Over-specifying the air system is a common and expensive mistake, because the shelling stage is widely assumed to need air. It does not.
Match the compressor to peeling head count: 30 HP for one head, 50 for two, 75 for three, 100 HP for four. Colour sorters can be plugged into the plant system instead of running their own compressor, but they do not have to be.
Where it fits in the process
A utility sized around peeling. Compressed air drives the peeling machine, a small part of the automatic vacuum packing line, and the colour sorters — shelling and cutting are mechanical and use none.
