Air & Vacuum for the Dairy, Food & FMCG Sector
Branded rice and grain plants live and die on the pack: vacuum and gas-flush packing keeps basmati and pulses stable on the shelf, and it all has to stay oil-free.
REQTypical duty requirements
Duty split for a branded rice / grain plant
| Duty | Air / vacuum | Recommended class |
|---|---|---|
| Vacuum / gas-flush packing | Oil-free vacuum | Dry vacuum pump |
| Grain pneumatic conveying | Low-pressure air | Turbine blower |
| Cleaning-line dust handling | Suction / air | Centrifugal / turbine |
| Bag / brick evacuation banks | Higher vacuum capacity | Dry vacuum pump (larger) |
CTXWhat this sector runs
The signature duty in a rice plant is vacuum packing — brick packs and pouches are evacuated (and often gas-flushed) so the grain travels and stores without spoilage. Because that vacuum is drawn right at the product, oil-free machines are the norm. High-throughput lines run banks of packing heads, which sets the vacuum capacity you have to plan for.
Around the pack line, the plant runs pneumatic conveying to move cleaned grain between silos, graders and packing, and light dust-handling air on the cleaning side. Those are low-pressure blower duties. The recommendation is oil-free dry vacuum for the packing heads and turbine air for conveying and dust.

ENGEngineering notes
Sizing vacuum to the head count
On a branded rice line the vacuum requirement scales with the number of packing heads drawing at once, not with a single head in isolation. A multi-head brick-pack line can pull several times the vacuum of one machine at peak, so the pump — or the bank of pumps — has to be sized to that simultaneous draw with margin for gas-flush cycles. Undersize it and packs seal poorly under load; the recommendation is to specify the peak header condition and match the oil-free YBDVP to it, with a spare ready because packing uptime is the whole plant's uptime.
Conveying without breaking grain
Moving cleaned basmati and pulses between silos, graders and packing is a dilute-phase conveying duty where gentleness matters as much as flow — too much velocity cracks grain and creates fines. A correctly sized single-stage turbine delivers the air volume to carry product at a controlled velocity rather than blasting it through the line. Matching the blower to the conveying rate and line length, rather than over-pressuring, protects both product quality and the conveying system, and the same class doubles for light cleaning-line dust air.
Packing uptime is plant uptime
On a branded grain line the packing floor is the plant's throat, so its vacuum uptime is effectively the plant's uptime — which makes the spares question the buying question. A machine sized to peak header draw with margin, a spare on the shelf and a domestic maker able to rebuild in days are what keep the packs sealing. Conveying blowers standardised onto a common family share spares with the pack line. For a rice plant where a vacuum drop stops dispatch, machinery chosen for how quickly it can be re-supplied domestically is machinery that keeps the whole line fed and moving.

WHYWhy Yash Blowers
Packing uptime is everything on a branded grain line, so the spares question is really the buying question. Yash Blowers builds in Faridabad, has done since 1998 under ISO 9001:2015, casts its own impellers, and dispatches 300+ machines a day — meaning a replacement dry pump or conveying blower is an Indian phone call, not an import cycle.

FAQFrequently asked questions
How much vacuum capacity does a rice packing line need?
It scales with the number of packing heads and the cycle time. A multi-head line usually needs a larger dry pump — or more than one — so the recommendation is to size the YBDVP to the peak simultaneous draw, not the single-head figure.
What moves cleaned grain between silos and packing?
Pneumatic conveying on low-pressure air, which is a turbine-blower duty. The single-stage YEBL-1 class covers dilute-phase grain conveying and light cleaning-line dust air.
