Cara Kerja Expeller Sekrup Pra-Tekan
The pengupas sekrup operates on a continuous prinsip penghancuran tipe sekrup. Oil seeds are fed into the hopper and carried forward by a rotating screw shaft inside a cylindrical barrel. As the seeds advance, the open space between the screw flights progressively narrows, creating increasing mechanical pressure. This pressure ruptures the oil-bearing cells, releasing crude oil that flows through perforated gaps in the barrel cage while the compressed seed cake exits at the discharge end. The shaft rotates at 1460 r/min, delivering consistent throughput with very low noise and vibration.
Why incorporate a mesin pra-tekan before the final hydraulic press? Hard-shelled seeds like rapeseed, flax seeds, and mustard seeds contain oil locked within tough cellular structures. A single-stage hydraulic press alone may only extract 60-70% of the available oil. The HN-CG60 pengusir biji minyak breaks open these cells first, softening the material and releasing approximately 35-40% of the oil in the pre-press pass. The partially de-oiled cake then enters the hydraulic press in an optimized state โ softer, warmer, and with oil already partly mobilized โ boosting the total hasil minyak sebesar 3-5%. This two-stage approach (screw pre-press โ hydraulic final press) is standard practice in commercial oil mills across India, Southeast Asia, and Africa for mustard, rapeseed, and groundnut processing lines. Importantly, the screw mechanism has tidak ada bagian yang mudah aus, keeping long-term maintenance costs near zero.
Skenario Aplikasi & Kasus Penggunaan
Pabrik Mustard & Rapeseed (India, Bangladesh, Nepal)
Mustard seed retains 15-20% residual oil after single-stage pressing. Adding an HN-CG60 pengupas sekrup as the first pass recovers an extra 3-5% โ that is 30-50 kg more oil per ton of seed processed. Indian mill owners typically see ROI within 2-3 months.
Pengolahan Biji Rami & Wijen (Afrika, Timur Tengah)
Flax seeds are small and hard, making direct hydraulic pressing inefficient. The HN-CG60 pengusir biji minyak softens flax and sesame through continuous crushing, improving cake porosity for the subsequent hydraulic press. Ethiopian and Nigerian buyers favor this machine for flaxseed throughput.
Jalur Kernel Kacang Tanah & Kenari (Asia Tenggara, Vietnam)
Versi standar 7,5 KW dapat menangani 300โ350 kg/jam biji kacang tanah โ ideal untuk produsen skala kecil hingga menengah di Vietnam dan Indonesia. Model 11KW yang ditingkatkan menggandakan throughput menjadi 750 kg/jam untuk pengoperasian volume tinggi.
Biji Lada & Minyak Khusus Sichuan (Ekspor China)
Sichuan pepper seeds (prickly ash) have a unique oil profile requiring gentle pre-crushing. The HN-CG60 screw mechanism handles these irregular seeds without clogging, making it a preferred mesin pra-tekan for specialty cold-pressed oil exporters.
Tip Pengoperasian & Praktik Terbaik
- Panaskan laras terlebih dahulu: Run the machine empty for 2-3 minutes before feeding. A warm barrel reduces initial seed friction and helps the first oil flow smoothly.
- Pemeriksaan kelembapan sebelum menyusui: Seeds with 6-8% moisture content produce the best pre-press results. Overly dry seeds generate excess fines; overly moist seeds produce emulsion instead of clean oil.
- Pertahankan laju pemberian pakan yang stabil: A uniform, consistent feed is critical. Overfeeding jams the screw; underfeeding reduces throughput and increases friction wear on the screw flights.
- Sesuaikan celah kerucut pelepasan: Tighten for smaller seeds (sesame, flax); loosen for larger kernels (peanuts, walnuts). Make adjustments in small increments while the machine is running.
- Rutinitas pembersihan harian: After each production run, feed a small amount of coarse bran through the mesin pra-tekan to absorb residual oil and clean the screw surfaces. Wipe down the barrel exterior.
- Pemeriksaan baki minyak: Keep the collection tray clean and free of sediment buildup. A clogged tray backs oil into the barrel housing, reducing extraction efficiency.
- Ketegangan sabuk motor : Check belt tension monthly. The 7,5 KW motor runs at 1460 r/min โ loose belts cause slippage, lower throughput, and premature belt wear.
Pertanyaan yang Sering Diajukan
Throughput apa yang bisa saya harapkan?
Standar: 300โ350 kg/jam. Ditingkatkan 11KW: 750 kg/jam. Hasil sebenarnya tergantung pada jenis benih dan kadar air.
Benih mana yang dapat digunakan dengan HN-CG60?
Rapeseed, kedelai, rami, biji lada Sichuan, wijen, kenari, kacang tanah, biji bunga matahari, biji kapas โ hampir semua biji yang mengandung minyak dengan ukuran kernel kecil hingga sedang.
Berapa harga dan syarat pengirimannya?
Hubungi kami melalui Ada apa atau email untuk harga FOB/CIF saat ini. Waktu pimpin: 7-15 hari kerja. Pengiriman: 15-35 hari ke pelabuhan utama di seluruh dunia.
Apakah pemeliharaannya mahal atau rumit?
Perawatan yang sangat rendah. Desain tanpa suku cadang berarti biaya suku cadang hampir nol. Pembersihan dedak setiap hari, pemeriksaan sabuk bulanan, pelumasan bantalan secara berkala โ itu saja.
Bagaimana cara membandingkannya dengan mesin press ulir yang berdiri sendiri?
Pengepres ulir mandiri melakukan ekstraksi sekali jalan dengan kecepatan 30-80 kg/jam. HN-CG60 melakukan pra-pengepresan dengan kecepatan 300-750 kg/jam โ kue kemudian dimasukkan ke dalam pengepres hidrolik. Dua tahap = lebih banyak oli + kualitas lebih baik.
Bisakah saya memasang mesin sendiri?
Ya. HN-CG60 kompak (1030ร1000ร750mm, 174kg). Itu tiba dalam keadaan lengkap. Tempatkan di permukaan yang rata, sambungkan ke 380V, dan mulai. Tidak diperlukan instalasi khusus.
