Pulping Operations (Step-by-Step SOP)

🔁 OVERVIEW

A successful pulping session =

✅ Right machine start-up

✅ Steady fruit feed

✅ No clogging

✅ Smooth pulp flow

✅ QC checks

✅ Clean & safe shutdown

________________________________________

⚙️ 8.1 Machine Start-Up (मशीन चालू करने की SOP)

StepActionNotes
1️⃣
Visual check of machine exteriorOil leakage? Loose wires?
2️⃣Check power connectionMCB ON, voltage stable (5–7 kW)
3️⃣Turn ON control panelGreen light = live power
4️⃣Run dry cycle for 1 minuteWithout fruit – to detect sound/vibration issues
5️⃣Check blades, mesh, outletNo obstruction, secure fit
6️⃣Test water inlet & pressureFor cleaning, safety

📍 Real Case: Bihar site skipped dry cycle – blade slipped → jam → 3 hrs delay. Always run DRY TEST!

🍎 8.2 Fruit Feeding (फल डालने की सही प्रक्रिया)

RuleDetail
AWash fruits with clean water + remove dirt/leaves
BCheck ripeness – avoid under-ripe or fermented
CRemove fruits with fungal spots, cuts
DFeed fruit slowly – don’t overload chute
EMaintain uniform feed rate – 10–15 kg per minute
FKeep helper with glove + stick to adjust flow (no hands inside!)

🔍 Tip: Use a graded crate system – green (pass), yellow (overripe), red (reject)

🧃 8.3 Pulp Extraction Process (पल्प निकलने की प्रक्रिया)

StepAction
1️⃣
Once fruit enters drum, blades crush and pulp flows out
2️⃣Mesh filters fibre, seeds, peel (varies by fruit)
3️⃣Pulp is directed to collection trough or drum
4️⃣Use sieve if needed for extra filtration
5️⃣Fill in pre-cleaned, labelled containers
6️⃣Maintain flow rate – don’t let pulp stagnate

🧰 Operational Norm:

1 operator per 1 machine

1 helper for adjusting flow & packing

📦 Pack Tip: Use double-check lid seal after pulp is cooled

🔍 8.4 In-Process Quality Check (चलती प्रक्रिया में क्वालिटी चेक कैसे करें?)

ParameterFrequencyHow to Check
Pulp thicknessEvery 30 minsStick test / flow test
Colour & shineEvery hourCompare with ref sample
Foreign matterContinuousVisual check during flow
Brix/sweetness (optional)Mid-shiftHand refractometer
Pack leak checkEvery batchPush + shake drum

📷 QC SOP: Click photos of 1 open pack every 3 hours – share to HO QA

🧼 8.5 Cleaning, Shift Changeover, Shutdown

A. Mid-Shift Clean (4+ hour ops)

• Use water spray, wipe outer body

• Clean pulp collection tray

• Check and clean mesh – fruit fibre often clogs it

B. End-of-Day Shutdown

StepAction
1️⃣
Switch off panel
2️⃣Drain water & pulp residue
3️⃣Clean inside drum with brush
4️⃣Remove mesh & wash separately
5️⃣Wipe control panel with dry cloth
6️⃣Log machine end status (clean? power off?)
7️⃣Lock tool box & store spares

📍 Staff Practice: Create a "Clean & Click" protocol – take photo of cleaned machine every evening

🧯 8.6 Downtime Handling (ब्रेकडाउन, जाम और रुकावट को कैसे संभालें?)

IssueLikely ReasonAction
Machine vibrationUnbalanced bladeStop – call engineer
Pulp not flowingMesh chokedPause – remove + clean
Excess motor noiseGearbox issueShut down – escalate to HO
Fruit jam at entryOverload or sticky fruitReduce feed + manually adjust
Electric tripSurge or wet wiringDry panel + retry – else call HO support

📦 Case Tip: Maintain downtime logbook – with start/end time, issue, action taken

________________________________________

⚠️ 8.7 If Not Done Properly… This Happens:

If SkippedConsequence
No dry runJammed blade, delay
Bad fruit fedRotten pulp, bad smell, batch rejection
Mesh not cleanedLow yield, motor strain
No QCCustomer complaints, rep loss
No clean shutdownFoul smell, pest risk
No downtime logHO can't support

✅ Final Thought:

"Pulp निकलता है मशीन से — पर मुनाफा निकलता है SOP से."

एक अच्छी पल्पिंग का मतलब है:

• मशीन steady

• टीम steady

• प्रॉसेस steady

Because in this business, it’s not about how many fruits you process. It’s about how cleanly and consistently you do it. 🍍⚙️🧼
