Rigorous Testing for Food
Hygiene & Pressure Safety
Industrial manufacturing equipment demands uncompromising quality control. At CV. Sentosa Teknik, our fabrication protocols follow dual engineering benchmarks: food-grade sanitary standards (SS304/SS316 with crevice-free finishes) for cracker processing machinery, and ASME-derived pressure vessel standards featuring mandatory 1.5x hydrostatic pressure testing certified by Disnaker RI for steam boilers.
Inspection Roadmap
Five Comprehensive Phases of Quality Assurance
Material Composition Audit
Incoming inspection of stainless steel plates using PMI spectrometer testing to confirm true SS304/SS316 grades. Pressure plate mill test certificates verified before cutting.
Welding Integrity & NDT
Precision argon TIG/MIG welding performed by certified welders. Critical pressure welds undergo liquid penetrant testing (NDT) to eliminate micro-cracks.
Mechanical Alignment & FAT
Assembled machinery runs a 4-hour continuous dry-run in our workshop. Laser measurement confirms dough roller parallelism and shaft runout within 0.1 mm.
Disnaker Hydrostatic Test
Steam boilers are filled with treated water and pressurized to 1.5x design pressure (15–20 bar) witnessed by government Disnaker inspectors for safety licensing.
Technical Dossier & Handover
Complete technical handover dossier provided with each unit: CAD electrical schematics, operating SOP manuals, Disnaker papers, and 12-month warranty certificate.
Food Machinery Hygiene vs. Pressure Boiler Safety Standards
Because food machines and steam boilers perform different roles, our engineering workshop applies specialized testing instruments and quality controls for each category.
Sanitary & Mechanical Standards
- ✓ Material Kontak: 100% Stainless Steel SS304/SS316 tahan karat makanan dan bumbu bergaram tinggi.
- ✓ Kualitas Permukaan Las: Las argon TIG saniter dihaluskan (Ra < 0.8 µm) tanpa sudut mati (dead zones) pemicu residu bakteri.
- ✓ Transmisi & Pelumas: Helical gear reducer menggunakan pelumas food-grade non-toxic untuk mencegah kontaminasi adonan.
- ✓ Fitur Keselamatan: Emergency stop button, pelindung interlock cover magnetik, dan tombol jog perlahan.
Pressure Vessel & Thermal Safety
- ✓ Plat Bejana Tekan: Menggunakan plat baja boiler standar bejana tekan (boiler quality steel) tebal 10–16 mm dengan sertifikat pabrik.
- ✓ Pengujian Hidrostatik 1.5x: Diuji dengan air bertekanan 15–20 bar disaksikan pengawas spesialis Disnaker RI.
- ✓ Katup Pengaman Ganda: Dilengkapi dual spring safety relief valve bersertifikat kalibrasi untuk mencegah risiko ledakan.
