Wafer Slicing Guide • Jarawala™ (Est. 1914, Sihor, Gujarat)

## How to choose between Single, 2-Blade, 3-Blade, 5-Blade, Jumbo, and Katri Potato & Banana Wafer Slicers?

Multi-blade rotary and manual wafer slicers from **Jarawala™** multiply slicing 
speed proportionally per hand stroke while keeping chip thickness uniform between**
0.5mm and 3.0mm** to prevent oil soggy centres. Choose the **[Single Blade Slicer (₹710)](https://jarawala.com/products/potato-banana-wafer-slicer/single-blade-wafer-slicer/)**
for home/small batches, the **[Jarawala Jumbo Wafer Slicer (₹1,150)](https://jarawala.com/products/potato-banana-wafer-slicer/jarawala-jumbo-potato-banana-wafer-slicer/)**
for wide raw banana coins and extra-large baking potatoes, the **[3-Blade (₹1,449)](https://jarawala.com/products/potato-banana-wafer-slicer/3-blade-slicer/)**
or **[5-Blade Slicer (₹1,650)](https://jarawala.com/products/potato-banana-wafer-slicer/5-blade-slicer/)**
for commercial hot-chips counters, and the **[Katri Slicer (₹695)](https://jarawala.com/products/potato-banana-wafer-slicer/katri-slicer-net-wafer/)**
for decorative crisscross net wafers.

## 2. How to Prevent Raw Banana Chips from Breaking During Slicing

 1. **Keep Moisture Tight:** Peel chilled raw green bananas immediately before slicing
    over heated palm or groundnut oil (or brine bath) so starch does not gum onto the
    cutting edge.
 2. **Calibrate Screw Depth (0.8mm–1.2mm):** Set Jarawala’s adjustable blade gap strictly
    at ~1.0mm for translucent banana wafers; going thinner than 0.6mm causes chipping,
    while exceeding 2.0mm creates chewy centres.
 3. **Clean Without Harsh Abrasives:** Flush starch off high-carbon stainless steel
    blades immediately with lukewarm water and dry thoroughly to keep edges razor-sharp
    across 4–6 months of heavy daily operation.

## 3. Frequently Asked Questions

Can blades be sharpened or replaced on Jarawala wafer slicers?

Yes. Jarawala wafer slicers (from Single Blade up to 5-Blade and Jumbo models) use
bolted stainless steel blades that can be removed for honing or replacement. Contact
our Sihor team on WhatsApp (+91 94277 77746) for genuine replacement blades.

How do I make crisscross net wafers (Katri chips)?

Use the dedicated [Katri Slicer (₹695)](https://jarawala.com/products/potato-banana-wafer-slicer/katri-slicer-net-wafer/)
and rotate the potato 90 degrees between each downward pass across the corrugated
steel plate.

Direct Comparison • Jarawala™ Extrusion Engineering (Est. 1914, Sihor, Gujarat)

## Manual Sev Sancha vs. Electric & Hydraulic Namkeen Extruders: Which Should You Choose?

A heavy-duty **Manual Hand-Operated Sev Making Machine (Sev Sancha)**—available 
from **Jarawala™** in **1 kg (₹1,800)**, **1.25 kg (₹1,950)**, and **1.5 kg (₹2,150)**
batch capacities with interchangeable free discs—is the ideal cost-effective choice
for retail sweet shops, street food stalls, catering halwais, and small batches 
up to 15–25 kg/day where operator dough feel matters most. Once daily demand exceeds
50–100+ kg/day or stiff low-moisture doughs (like thick Tikha Ganthiya, Murukku,
or Bikaneri Bhujia) must extrude continuously, motorized **Rotary/Hydraulic Namkeen
Extruders** paired with CNC-punched **5″–10″ SS 304 Namkeen Machine Discs (Jalis)**(
starting at **₹170**) eliminate operator fatigue and triple hourly throughput.

## 1. Side-by-Side Technical Comparison Matrix

  |  Specification |  Manual Sev Machine (1 kg – 1.5 kg) |  Rotary Electric Extruder (5″–7″) |  Industrial Hydraulic Extruder (8″–10″) |

## 2. Why Die Metallurgy Matters Just As Much As Extruder Torque

Upgrading to a 2 HP or hydraulic extruder immediately exposes weak dies. Lightweight
thin-sheet stamped plates warp under continuous bar pressure, distorting hole pitch
and tearing brittle dough strands. Pair every commercial extruder with CNC laser-
punched SS 304 dies detailed in our [Namkeen Machine Disc Sizing Chart (OD & Bore Reference)](https://jarawala.com/namkeen-machine-disc-sizing-chart-diameter-bore-guide/)
and [SS 304 vs. Brass Metallurgy Guide](https://jarawala.com/stainless-steel-vs-brass-namkeen-extruder-dies-comparison/).

# Stainless Steel (SS 304) vs. Brass Extruder Dies: Commercial Production & Heat Longevity Guide

A rigorous metallurgical comparison for snack manufacturing plants, namkeen factory
managers, and commercial food engineering procurement teams to optimize die wear
life, dough friction, and FSSAI compliance.

## 1. The Metallurgy of Namkeen Extrusion

In continuous commercial snack processing, the **extruder disc (jali)** endures 
relentless abrasive friction from fiber-rich gram flour (besan), salt crystals, 
spices, and dough binders under hydraulic pressures exceeding **120 to 180 bar**.
Choosing between **Austenitic Stainless Steel (SS 304)** and **High-Tensile Brass(
CW614N / IS 319)** significantly affects production uptime, sanitation schedules,
and cost-per-kilogram extruded.

## 2. Head-to-Head Engineering Comparison Matrix

### Metallurgical Scorecard • SS 304 vs. High-Tensile Brass

 Industrial Benchmark

  |  Engineering Property |  Food-Grade SS 304 |  High-Tensile Brass (IS 319) |  Winner / Recommendation |  
   |  **Tensile Strength (MPa)** |  515 – 620 MPa (Extreme rigidity) |  380 – 450 MPa |  **SS 304:** Superior resistance to bowing under 150+ bar hydraulic pressure. |  
 |  **Abrasive Wear Lifespan** |  3,500 – 5,000+ Running Hours |  1,800 – 2,400 Running Hours |  **SS 304:** Extends die replacement interval by over 100%. |  
 |  **Surface Friction Coefficient** |  0.28 – 0.32 (CNC electropolished) |  0.20 – 0.24 (Naturally self-lubricating) |  **Brass:** Smoother dough flow on aerated, low-moisture ganthiya doughs. |  
 |  **Corrosion & Salt Resistance** |  Zero oxidation; immune to vinegar, citric acid & high salt |  Susceptible to surface verdigris if exposed to acids/moisture |  **SS 304:** Undisputed gold standard for shelf stability and FSSAI audits. |  
 |  **Thermal Conductivity** |  16.2 W/m·K (Slow heat transfer) |  115 W/m·K (Rapid heat dissipation) |  **Brass:** Dissipates hydraulic frictional heat faster, keeping dough cooler. |  
 |  **CIP & Caustic Cleanability** |  100% compatible with hot caustic soda (NaOH) washes |  Tarnishes heavily; requires gentle manual detergent cleaning |  **SS 304:** Essential for automated Clean-In-Place (CIP) factory lines. |

## 3. Application Guide: When to Choose SS 304 vs. Brass

### A. When to Choose Food-Grade Stainless Steel (SS 304)

 * **Automated Continuous High-Volume Lines:** If your plant extrudes over 80 kg
   to 250 kg per hour with hydraulic or pneumatic rams.
 * **High-Salt & Acidic Formulations:** When extruding chatpata sev, tomato-chilli
   bhujia, or products formulated with citric acid, dry mango powder (amchur), or
   high salt percentages.
 * **Export & Tier-1 Quality Certifications:** SS 304 is mandatory for USFDA, BRCGS,
   ISO 22000, and corporate FSSAI compliance where copper-leaching risks are strictly
   prohibited.

### B. When to Choose High-Tensile Brass

 * **Traditional Bhavnagari & Papdi Ganthiya:** Brass’s natural self-lubricating
   low friction allows soft, highly aerated oil-emulsified doughs to glide through
   ribbon and oblong orifices without tearing.
 * **Manual Hand-Operated Sev Sanchas:** The lower coefficient of friction substantially
   reduces operator arm fatigue during continuous manual pressing ([see Manual vs. Electric Extruder Comparison](https://jarawala.com/manual-sev-sancha-vs-electric-hydraulic-namkeen-extruder-guide/)).
 * **Murukku & Chakli Forming:** Rice flour doughs release with crisp, sharp edges
   when pressed through CNC brass star dies.

#### Jarawala Proprietary CNC Laser Piercing Technology

Regardless of whether you choose SS 304 or High-Tensile Brass, all Jarawala extruder
dies are cut on high-power fiber laser systems and mirror-finished. We ensure that
hole throats feature engineered entrance funnels that eliminate dough stagnation
zones and prevent thermal discoloration. Also check our [OD & Bore Sizing Chart](https://jarawala.com/namkeen-machine-disc-sizing-chart-diameter-bore-guide/).

## 4. Frequently Asked Questions (FAQ)

Can I wash brass extruder dies in caustic cleaning solutions?

No. Caustic soda (sodium hydroxide) and strong acid descalers will corrode and pit
brass surfaces, destroying hole tolerances. For brass dies, clean with warm water
and neutral food-grade degreasers. If your plant relies on automated caustic CIP
washes, switch to Jarawala SS 304 extruder plates.

Does Jarawala manufacture custom brass dies for imported machines?

Yes. We manufacture custom brass and stainless steel dies for all domestic and imported
snack extruders, matching exact metric or imperial outer diameters, bolt circles,
keyways, and thickness requirements.

What is the delivery turnaround time for custom dies?

Standard sizes (5″ to 8″ OD) ship within 24 to 48 hours from our Sihor, Gujarat 
manufacturing facility (Pan-India transit 1–6 days; Gujarat ₹70/kg, Rest of India
₹100/kg). Custom blueprint CNC dies typically ship within 3 to 5 business days across
India.

Master Halwai Guide • Luhar Girdher Devji & Sons (Est. 1914, Sihor)

# How to Select the Perfect Motichur Laddu Jara Hole Size (No. 0, 1, 2 & 3 Selection Guide)

A master sweet-maker’s technical guide to perforated jara gauge selection, droplet
fluid dynamics, and frying techniques for crafting authentic micro-pearl motichur
laddus and sweet boondi.

## 1. Fluid Dynamics: Why Jara Hole Size Dictates Boondi Quality

Authentic **Motichur Laddu** (literally _“crushed pearls”_) requires exceptionally
tiny, perfectly spherical boondi pearls that melt upon the tongue. Unlike large 
savory raita boondi, motichur boondi demands strict synchronization between three
physical variables:

 * **Perforation Hole Diameter:** Governs droplet volume before capillary break-
   off into hot ghee or oil.
 * **Batter Surface Tension & Viscosity:** Gram flour (besan) batter must be silky,
   smooth, and free of lumps with ribbon consistency.
 * **Jara Tapping Impact Force & Height:** Holding the jara 3 to 4 inches above 
   the oil surface ensures the droplet forms a sphere rather than elongating into
   a tail.

## 2. Master Motichur Jara Gauge Matrix (No. 00 to No. 3)

In traditional Indian sweet manufacturing, jara hole gauges follow an inverted numbering
system. Below is the official sizing matrix engineered by Jarawala for commercial
sweet caterers and halwai shops ([shop commercial Motichur Jara ₹740](https://jarawala.com/products/motichur-jara/motichur-laddu-making-jara/)):

### Motichur & Boondi Jara Hole Size Matrix

 Material: SS 304 Food Grade / Brass

  |  Jara Number |  Exact Hole Gauge (mm) |  Perforation Density |  Target Culinary Sweet |  Droplet Texture |  
   |  **No. 00 (Double Zero)** |  **0.7 mm – 0.9 mm** |  Ultra-Dense Micro Punch |  Royal Shahi Motichur Laddu |  Pin-head micro-pearls; dissolves effortlessly in sugar syrup. |  
 |  **No. 0 (Single Zero)** |  **1.0 mm – 1.2 mm** |  Dense Perforated Bowl |  Standard Commercial Motichur Laddu |  Classic sweet shop pearl size; holds moisture without sogginess. |  
 |  **No. 1** |  **1.4 mm – 1.6 mm** |  High-Flow Hemispherical |  Tirupati Style Laddu / Prasad Boondi |  Plump, succulent pearls with firm bite. |  
 |  **No. 2** |  **1.8 mm – 2.2 mm** |  Medium Halwai Punch |  Meethi Boondi / Sugar-Syrup Boondi |  Large, juicy boondi for festive wedding platters. |  
 |  **No. 3** |  **2.5 mm – 3.2 mm** |  Open Drainage Grid |  Raita Boondi & Masala Boondi Namkeen |  Crunchy, crisp savory namkeen boondi. |

## 3. Four Secrets to Eliminating “Tailed” or Flat Boondi

Every commercial halwai has encountered the frustration of boondi falling with sharp
pointy tails or collapsing flat. Here is how our metallurgical engineering prevents
common defects:

 1. **Burr-Free Perforations:** When sheet metal holes are punched with dull dies, 
    jagged metal microscopic burrs drag on the dropping batter, stretching it into 
    a tear shape. Jarawala motichur jaras are punched on high-precision presses and
    electropolished to guarantee zero burrs.
 2. **Constant Oil Temperature (175°C to 180°C):** If the frying kadai is cooler than
    175°C, the droplet flattens upon contact with oil before surface tension can seal
    the sphere. If too hot (>190°C), the exterior hardens before the interior expands,
    creating hollow shells.
 3. **Wiping the Underside Between Batches:** Always use a damp clean cloth to wipe
    the bottom of your jara after every tap. Dried batter residue around the hole rim
    alters the diameter, immediately producing uneven boondis.
 4. **Optimal Tapping Cadence:** Gently tap the jara handle against the edge of the
    kadai or your left palm. Never strike violently; let gravity and kinetic vibration
    release uniform droplets.

#### Stainless Steel 304 vs Heavy Brass Motichur Jaras

Historically, halwais favored brass for its aesthetic heft. However, modern commercial
sweet manufacturers have transitioned exclusively to **Food-Grade Stainless Steel(
SS 304)**. SS 304 does not react with sugar syrups or acidic batter, never tarnishes,
and is 100% compliant with FSSAI hygiene audit norms. Planning an entire sweet &
farsan counter? See our [Commercial Namkeen & Farsan Business Equipment Checklist](https://jarawala.com/commercial-namkeen-farsan-business-equipment-checklist/).

## 4. Frequently Asked Questions (FAQ)

Which jara number should I buy for authentic Motichur Laddu?

For authentic royal micro-pearl motichur laddu, select **No. 0 (1.0mm)** or **No.
00 (0.8mm)**. If you are preparing temple-style or traditional Tirupati-style laddu,
choose **No. 1 (1.5mm)**.

What handle sizes are available on Jarawala Motichur Jaras?

Our motichur jaras feature 18″ to 30″ heavy forged iron handles with heat-insulating
wooden grips, engineered to keep the sweet-maker’s hands safely away from large 
commercial boiling kadais.

Can Jarawala manufacture custom bowl diameters for large sweet factories?

Yes. We supply 12″, 14″, 16″, 18″, and 20″ bowl diameters in both deep-dome and

# Namkeen Machine Disc Sizing Chart: Outer Diameter, Bore & Hole Selection Guide

A comprehensive engineering guide for snack food processors, industrial halwais,
and farsan manufacturing units to select the exact outer diameter (OD), shaft bore,
keyway, and CNC hole gauge for automatic and manual extruders.

## 1. Extrusion Physics: Why Precision Fitment Matters

In high-capacity commercial snack production, your **namkeen extruder disc (jali)**
is the single critical orifice governing flow velocity, shear rate, dough temperature,
and motor amperage. Selecting an improperly sized disc creates severe manufacturing
bottlenecks:

 * **Excessive Hydraulic Backpressure:** When hole perforation percentage is too
   low, cylinder backpressure spikes by up to 45%, straining hydraulic pumps, wearing
   gear teeth, and overheating dough (causing oil separation).
 * **Center Shaft Slippage:** A center bore that is even 0.5mm oversized will chatter
   against the driving shaft under 150+ bar pressure, rounding out the keyway and
   damaging your main transmission.
 * **Non-Uniform Strand Breakage:** Burred or rough punched holes create micro-drag
   on sev or ganthiya dough, causing curled, fractured strands instead of uniform,
   straight commercial lengths.

## 2. Master Sizing Matrix: Outer Diameter & Center Bore

Commercial rotary namkeen extruders deployed across Gujarat, Madhya Pradesh, Tamil
Nadu, and pan-India plants adhere to standardized disc sizing envelopes. Below is
the master fitment matrix precision-manufactured at Jarawala’s Sihor foundry:

### Standard Commercial Extruder Disc Dimensions

 Tolerances: ±0.05mm

  |  Outer Diameter (OD) |  Center Bore ID |  Standard Keyway |  Disc Thickness |  Machine Types |  
   |  **5.0″ (127 mm)** |  19 mm / 22 mm |  5 mm × 2.5 mm |  4.0 mm – 5.0 mm |  Semi-Automatic & Tabletop Extruders |  
 |  **6.0″ (152 mm)** |  22 mm / 25.4 mm (1″) |  6 mm × 3.0 mm |  4.5 mm – 6.0 mm |  Standard Commercial Rotary Machines (40–80 kg/hr) |  
 |  **7.0″ (178 mm)** |  25.4 mm / 28 mm |  8 mm × 3.5 mm |  5.0 mm – 6.5 mm |  Heavy-Duty Continuous Extruders (80–140 kg/hr) |  
 |  **8.0″ (203 mm)** |  28 mm / 32 mm |  8 mm × 4.0 mm |  6.0 mm – 8.0 mm |  Industrial High-Capacity Hydraulic Extruders (120–200 kg/hr) |  
 |  **9.0″ & 10.0″ (Custom)** |  32 mm – 42 mm |  10 mm × 4.5 mm |  8.0 mm – 10.0 mm |  Tier-1 Automated Continuous Processing Lines |

## 3. Hole Gauge & Perforation Sizing for Core Snack Varieties

Different namkeen formulations—from ultra-fine nylon sev to thick, airy bhavnagari
ganthiya—require exact perforation geometry to ensure smooth dough passage and optimal
oil absorption during deep frying:

### Snack-Specific Hole Geometry Reference

 Material: SS 304 Food Grade

  |  Snack Variety |  Hole Geometry |  Exact Dimensions |  Dough Viscosity |  Ideal Frying Kadai Temp |  
   |  **Nylon Sev / Barik Sev** |  Round Micro-Punch |  0.8 mm – 1.0 mm |  Medium-Soft (Pourable) |  175°C – 180°C (Instant 15s flash fry) |  
 |  **Ratlami Sev / Bhujia** |  Clover / Round Slit |  2.0 mm – 2.5 mm |  Firm Spiced Besan |  170°C – 175°C |  
 |  **Bhavnagari Ganthiya** |  Oblong / Fluted Slit |  3.5 mm – 5.0 mm |  Soft, Aerated Oil-Emulsified |  160°C – 165°C (Gentle puffing) |  
 |  **Papdi Ganthiya** |  Flat Ribbon Slit |  8.0 mm × 1.2 mm |  Elastic Soda-Bi-Carb Dough |  165°C – 170°C |  
 |  **Murukku & Chakli** |  Star / Fluted Star (3 & 4 Point) |  3.0 mm – 4.0 mm |  Rice & Urad Flour Stiff Dough |  165°C – 170°C |  
 |  **Boondi (Sweet / Salted)** |  Hemispherical Punch |  1.8 mm – 3.0 mm |  Free-Flowing Liquid Batter |  180°C – 185°C |

#### Pro Engineering Tip • Caliper Measurement Protocol

When measuring your old disc for replacement, always measure using a digital vernier
caliper across two perpendicular diameters to check for ovality. For the center 
bore, measure from the inside walls excluding the keyway cut-out. If your machine
model lacks markings, our engineering team can match your fitment from a single 
high-resolution photograph and three caliper readings.

## 4. Frequently Asked Questions (FAQ)

Can Jarawala manufacture custom outer diameters or bore sizes?

Yes. In addition to our standard 5″ to 10″ inventory, Luhar Girdher Devji & Sons
operates an advanced in-house CNC wire-cut and laser shop. We routinely manufacture
custom ODs, non-standard keyways, splines, and proprietary multi-slit patterns to
client blueprints.

How do CNC mirror-punched holes improve dough throughput?

Traditional mechanical punching leaves micro-burrs and tapered shear edges on the
disc exit side, causing dough friction and frequent clogging. Jarawala CNC laser-
punched discs feature mirror-smooth entry and exit chamfers that reduce frictional
resistance by 30%, allowing continuous extrusion without burning or surging.

Which is better for high-production lines: SS 304 or Brass?

SS 304 is the industry gold standard for continuous high-acid, high-salt, and FSSAI-
compliant automated manufacturing because it never corrodes, oxidizes, or reacts
with spices. High-tensile brass is prized by traditional halwais for low coefficient
of friction on soft ganthiya doughs. See our [SS 304 vs Brass Die Comparison](https://jarawala.com/stainless-steel-vs-brass-namkeen-extruder-dies-comparison/)
or [Manual vs. Electric Extruder Guide](https://jarawala.com/manual-sev-sancha-vs-electric-hydraulic-namkeen-extruder-guide/).
