Top 5 Automated Durian Processing Tools in SG Hub

The “SG Hub” here is not a marketing term. It is the Sungai Rengit–Pasir Gudang corridor, plus Singapore re-export nodes, where the bulk of Musang King and D24 volume gets split, graded, frozen, and packed for China and Hong Kong. Hand-peeling still dominates small Chinese orchards, but export-grade processing in this corridor runs on fixed machines. The five tools below are the ones physically bolted down on concrete floors in actual plants along that 60 km belt.

1. Exseed EX-3000 Auto Splitting Line

Penang fabricator Exseed Technology builds the most deployed durian splitting machine in the corridor. The EX-3000 uses dual rotary blades bracketed at a fixed 45-degree attack angle and a pair of pneumatic clamps that hold whole fruits between 0.8 kg and 4 kg. The operator loads a fruit, steps on a floor pedal, and the machine scores the husk in one pass without cutting into the flesh chamber. Rated output is roughly 800 fruits per hour with three operators on the line, replacing the 12 to 15 manpower required for traditional parang splitting.

The unit runs on 380 V three-phase, sits on a stainless A-frame, and drops into any roller conveyor layout. Logistics notes: plants at Sungai Rengit pair two EX-3000 units in parallel, then send split husks straight into a brine flotation trough to separate seeds from flesh. Spare blade cartridges are available locally from Exseed’s Bukit Tengah workshop, which matters more than uptime paperwork in this region.

2. TOMRA 5C NIR Sorting Cell

Fresh durian flesh is sticky, fibrous, and full of seed fragments right after extraction. The TOMRA 5C is the standard answer in the SG Hub for removing blemished meat, husk shards, and immature seeds before freezing. It uses NIR and VIS spectroscopy with bi-chromatic cameras to classify every single flowing piece by moisture content and color. The ejection system fires high-pressure air jets at the lateral edge of the belt, not at the product surface, which reduces smearing of wet pulp.

Throughput on a typical half-frozen durian cube line in Pasir Gudang is 10 to 12 tonnes per hour, depending on cube size and blemish threshold settings. Most integrators in this region run a two-pass setup: coarse pass for foreign material, fine pass for internal browning. It is not a cheap machine, but no SG Hub plant exporting to China passes customs without this level of optical inspection.

3. JBT GYRoCOMPACT 76 Spiral Freezer

Frozen Musang King pulp cubes leave Singapore and Johor plants only if they hit a core temperature of −18°C or lower within a known dwell window. The JBT GYRoCOMPACT 76 is the workhorse spiral freezer you will find in the Pasir Gudang cold chain cluster. It uses a self-stacking stainless belt that forms a compact, 4.5-meter-square tower while holding 76 running meters of product belt. Internal air temperature runs at −40°C, giving a 45-minute dwell time for 25 g pulp cubes at roughly 2,000 kg per hour.

The key operational fact for this hub: durian fats do not freeze cleanly in static blast rooms. The spiral freezer’s vertical airflow prevents the development of a semi-frozen sticky skin that welds cubes together. Plants exporting whole frozen fruits also use the GYRoCOMPACT for a pre-chill pass before vacuum packing.

4. Tetra Pak Aseptic Paste Line

For D24 and Musang King paste destined for the pastry and bubble-tea trade in China and Hong Kong, the SG Hub standard is a Tetra Pak tubular aseptic processing system. The line runs paste through a tubular heat exchanger at 138°C with a 5 to 10 second hold time, then cools and fills into 200 kg aseptic bag-in-box stainless bins. Output on a typical two-line installation is 2,500 liters per hour.

Durian-specific issue: plate heat exchangers give this paste a detectable metallic taste because the fruit’s high fat content strips ions from stainless plates. Tubular designs avoid that. Plants in the corridor run this line continuously, not in batches, because the cleaning-in-place cycle takes nearly two hours. If you are visiting a plant, the main giveaway is the tall sterile tank farm next to the filler room — the capital cost of cleaning validation is the real barrier to entry.

5. Thermo Fisher microPHAZIR Handheld

The bottleneck at the SG Hub receival gate is not weight. Lorries pull in from Raub, Bentong, and Segamat with mixed loads, and every fruit must be graded for dry matter before it goes to the splitting line. The Thermo Fisher microPHAZIR is the portable NIR analyzer used inside the hub for exactly this. It scans a 1600 to 2400 nm wavelength range and returns a dry matter percentage in under two seconds, without cutting the husk.

Field practice at Sungai Rengit receival stations: 12 fruits per lot are scanned, the average dry matter reading is logged against a grower QR batch tag, and grade tiers are applied on the spot — premium fruit at 30% and above dry matter gets routed to the IQF line, while the rest goes to the paste line. The unit handles routine dust, rain, and 34°C ambient heat well, although the IR sensor window needs wiping every few hundred scans when processing the waxier Musang King variety.
