Client Background & Why They Came to Us<\/h2>\n\n\n\n

Pak Hendra’s family had been running a small snack workshop in Bandung since 2017. They started with three manual woks and two staff, frying keripik kentang<\/em> by hand and supplying neighborhood warung<\/em> and a couple of pasar tradisional<\/em> vendors. By early 2024 things had changed \u2014 a regional minimarket chain (similar in size to a small Alfamart franchise group) offered them a private-label contract for 18 tons per month. Their existing setup could do maybe 4 tons. The math did not work.<\/p>\n\n\n\n

Hendra found us through a fairly specific Google search \u2014 he told us later he typed something like “potato chips production line manufacturer 300kg Indonesia”<\/em> and clicked through three suppliers before sending an inquiry. What tipped his decision was not the price (we were not the cheapest), but a 12-minute factory walkthrough video our sales engineer Dewi sent him over WhatsApp, where she actually ran a slicer on real Granola potatoes and showed the slice thickness measurement live.<\/p>\n\n\n\n

His three biggest worries before signing the contract were, in his own words:<\/p>\n\n\n\n

\n

“First, I worry the chips will turn brown \u2014 Indonesian potatoes have a lot of sugar. Second, I worry about oil cost, palm oil price keeps going up. Third, I do not want to hire more than 6 people per shift, finding workers in Bandung is harder now.”<\/p>\n<\/blockquote>\n\n\n\n

These three worries became the backbone of the entire project \u2014 and honestly, the first one almost embarrassed us during trial runs.<\/p>\n\n<\/div>\n\n

\n\n

Raw Material & End-Product Positioning<\/h2>\n\n\n\n

Pangalengan, about 45 km south of Bandung city, sits at roughly 1,400 m elevation and is one of the few areas in Indonesia where Atlantic and Granola potato varieties grow with reasonable consistency. Hendra’s supply contract locked in 8 tons\/week from two farmer cooperatives. The challenge with Indonesian highland potatoes is well-known among local processors: reducing sugar content can swing between 0.15% and 0.42% depending on storage temperature and harvest age<\/strong>, which directly affects Maillard browning during frying.<\/p>\n\n\n\n

The end products were positioned for two channels:<\/p>\n\n\n\n

\u0627\u0644 modern channel<\/strong> (the minimarket private-label contract) needed 35g pillow bags with nitrogen flushing, shelf life 6 months, target retail price IDR 5,500. The traditional channel<\/strong> kept Hendra’s original brand alive in 75g bags sold through pasar<\/em> and small warung<\/em>, with three flavors: original asin<\/em>, bumbu balado<\/em>, and jagung manis<\/em> (sweet corn). The slicing target was a 1.4 mm flat slice \u2014 slightly thinner than the previous hand-cut 1.8 mm, to match the modern-channel competitor on bite-feel.<\/p>\n\n\n\n

We did not design this line for wave-cut or compound chips. Keeping the scope tight was deliberate; mid-scale clients who try to do everything in one line usually regret it within 18 months.<\/p>\n\n<\/div>\n\n

\n\n

Process Flow & Equipment Configuration<\/h2>\n\n\n\n

The full process from raw potato intake to sealed bag goes through 11 stations. Below is the simplified flow.<\/p>\n\n\n\n

Total connected load is around 64 kW<\/strong>, but the running load during normal production sits at roughly 38\u201342 kW<\/strong> because the blanching electric heating and the fryer are not at peak simultaneously. This was an important number for Hendra \u2014 his existing PLN connection was 53 kVA and we wanted to avoid forcing him to upgrade the transformer.<\/p>\n\n\n\n

A small detail worth mentioning: the fryer is gas-fired (LPG), not electric<\/strong>. In Bandung, LPG is significantly cheaper per kWh-equivalent than electricity for industrial heating, and the client already had a 12-tank LPG manifold from his previous frying operation. We reused it.<\/p>\n\n\n

Layout & On-site Implementation<\/h2>\n\n\n\n

The workshop measures roughly 240 m\u00b2 with 4.8 m clear ceiling height. We laid out the line in an L-shape<\/strong> rather than a straight line because the building had a load-bearing column inconveniently placed at the 14-meter mark. The wet section (washing \u2192 blanching) runs along the north wall, then the line turns 90\u00b0 and the dry section (frying \u2192 packaging) runs along the east wall, ending near the loading door.<\/p>\n\n\n\n

Shipping took 31 days<\/strong> from Qingdao port to Tanjung Priok, then another 4 days by truck up to Bandung. Customs cleared in 6 working days \u2014 slightly slower than usual because two of the HS codes triggered a manual inspection. Installation on-site took 11 days<\/strong>, plus 6 days of trial runs and operator training. Two of our engineers (Mr. Liu, mechanical, and Mr. Zhao, electrical) flew in with a Bahasa-Mandarin translator from our Surabaya agent partner.<\/p>\n\n\n\n

The one thing that did not go smoothly: the workshop floor was not done with food-grade epoxy when we arrived. Hendra had a local contractor doing it in parallel, but the curing time forced us to delay anchor bolting by 3 days. Lesson learned \u2014 we now send a pre-installation checklist to clients 30 days before container loading. It includes floor finish, drainage slope, exhaust hood position, and PLN load confirmation.<\/p>\n\n<\/div>\n\n

\n\n

Challenges & Solutions<\/h2>\n\n\n\n

This is where the project earned its keep. Three real problems came up, and only one of them was anticipated in the original proposal.<\/p>\n\n\n\n

Challenge 1: First-batch chips came out too dark<\/strong><\/h3>\n\n\n\n

During the second day of trial runs, the chips coming out of the fryer were noticeably darker than the reference samples Hendra had approved. Color L-value measured around 58, target was 65\u201370. The root cause was exactly what Hendra had warned us about: the Pangalengan potatoes that week had a reducing sugar content of 0.38%, on the high side. Our default blanching parameters (75\u00b0C \u00d7 60s) and frying temperature (170\u00b0C) were tuned to typical Chinese Atlantic potatoes with 0.18\u20130.22% reducing sugar.<\/p>\n\n\n\n

The fix was a two-step adjustment. We extended blanching to 78\u00b0C \u00d7 75 seconds<\/strong> to leach out more reducing sugars, and we lowered the fryer inlet temperature to 165\u00b0C<\/strong> with a 12-second longer residence time to compensate. By day 4 the L-value was back at 67. Honestly, this was not a brilliant engineering moment \u2014 it was just paying attention to what the client had told us upfront. We should have tuned the recipe before leaving the factory.<\/p>\n\n\n\n

Challenge 2: Oil consumption higher than promised<\/strong><\/h3>\n\n\n\n

Initial oil consumption measured at 38 L per 100 kg finished product<\/strong>, while our proposal had estimated 32 L. After two days of investigation we found the de-oiling centrifuge was running at 320 rpm instead of the rated 380 rpm \u2014 a wiring mistake during installation had bridged two phases incorrectly on the VFD. After correction, residual oil dropped from 27% to 21%, and overall oil consumption settled at 33\u201334 L per 100 kg<\/strong>. Not exactly the 32 L target, but within the agreed tolerance.<\/p>\n\n\n\n

Challenge 3: Slice thickness drift after 4 hours of running<\/strong><\/h3>\n\n\n\n

By the 4th hour of continuous running, slice thickness was creeping from 1.4 mm to 1.55 mm, which the operator only caught because the chips were taking longer to fry. The slicer blade gap had drifted because of thermal expansion in the cutter head \u2014 a known issue with our older SL-300 model when running hot potatoes straight from blanching makeup water. We adjusted the line so that operators measure slice thickness with a digital caliper every 90 minutes and re-shim the blade head if drift exceeds 0.1 mm. Not elegant, but it works. The next-generation SL-300H has an auto-compensation mechanism, which we offered to upgrade Hendra to in 2026.<\/p>\n\n<\/div>\n\n

\n\n

Production Data & Client Validation<\/h2>\n\n\n\n

After the first 90 days of stable production, the operations team compiled the following numbers (we asked Bu Sari, the production supervisor, to share the report).<\/p>\n\n\n\n

Metric<\/th>Target<\/th>Actual (90-day average)<\/th><\/tr><\/thead>
Output capacity<\/td>300 kg\/h<\/td>289 kg\/h (96.3%)\u200b<\/strong><\/td><\/tr>

Oil consumption<\/td>32 L\/100kg<\/td>33.6 L\/100kg<\/td><\/tr>
Operators per shift<\/td>6<\/td>5<\/td><\/tr>

Color L-value<\/td>65\u201370<\/td>66.8 (avg)<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

The 96.3% capacity achievement is realistic \u2014 the 3.7% gap mostly comes from the 12-minute oil-filtration cleaning cycle every 4 hours, which the original spec sheet did not account for. Hendra’s comment three months in:<\/p>\n\n\n\n

\n

“The line runs OK. Not perfect \u2014 we still have small problems with the seasoning drum sometimes \u2014 but my workers can run it without me being in the workshop. That is what I needed.”<\/p>\n<\/blockquote>\n\n\n\n

Not the most enthusiastic testimonial, but for a B2B equipment project, “the line runs and the boss doesn’t need to babysit it” is honestly a pretty good outcome.<\/p>\n\n\n
