Packing mustard seeds starts with measuring bulk behaviour on your floor, not copying another factory’s HMI recipe. For Mustard Seeds, plan around 0.70–0.80 g/ml bulk density and 28–36% seed oil if crushed as the primary materials variables. Recommended metering is volumetric cup filler (fill code CUP). YugMach publishes configuration prices from Mathura so buyers get price transparency before GST; final figures still follow pouch size, film, and options. On mustard seeds lines, seal development usually begins near 120–150°C with dwell in the 0.4–1.0 s band, then moves after peel tests on your laminate lot. Gas or barrier target context is moisture barrier primary. Typical films include BOPP/PE, LDPE laminate, Printed poly laminate. Pouch bands commonly cover 100g–250g, 500g, 1kg. Planning throughput sits near 1,500–3,000 when product, film, and changeovers cooperate. Critical failure modes unique to mustard seeds: hard spherical abrasion; cup lip wear; crush oil seepage; insect-proof seals; high density drop stress. Design SOPs and spare kits around those five, not around generic ‘packing machine maintenance’ checklists. Keep free-fall near 450 mm or lower when fracture or dust generation is a risk for this SKU family. Gas flushing is usually secondary or irrelevant for mustard seeds; moisture, alkalinity, count accuracy, or wrap integrity dominate instead. Spend engineering time on WVTR, corrosion resistance, and seal cleanliness rather than nitrogen plumbing you will never use. Weight control economics for mustard seeds: about 3 g average giveaway at 2,000 packs/hour wastes 6 kg/hour of product. Multiply by your factory cost per kilogram to size the payback for better tooling, more heads, or closed-loop checkweighing. Calibrate weekly with certified test weights and after any collision on the filler frame. Mechanical envelope: expect on the order of 3.2 kW class connected load depending on servos and heaters, and roughly 6 bar clean dry air if actuation is pneumatic. Film path width planning around 160 mm face/web context is a common starting point for mid retail SKUs, but collar selection must match the actual formed cross-section. Wrong collars score film, wander longitudinal seals, and create scrap that looks like a temperature problem. Mustard seeds are hard and near-spherical at 0.70–0.80 g/ml; cups work when size is uniform and lips are unworn. Micrometer cup lips monthly — abrasive wear opens volumetric error slowly until QC notices a trend. Aggressive screws crush seeds and release 28–36% oil onto film, destroying seals. Insect-proof seals and intact corners matter for agro retail; pinholes invite infestation claims. 500 g–1 kg packs need drop-test validation from 0.8–1.2 m because dense product stresses seals. Housekeeping for mustard seeds must match chemistry: wipe intervals, extractor filter changes, and elastomer replacement differ from a dry rice demo line. Never hose electrical cabinets. Dry contact parts fully after wet cleaning before restart. Document screw RPM or weigher combination limits, seal temperature, and flush settings on a laminated card at the machine for each mustard seeds SKU. Factory acceptance should include at least three steady hours on the hardest mustard seeds SKU with agreed scrap and weight or count tolerances. Record film lot, ambient °C, and RH — monsoon air in North India changes powder flow and snack oil feel. Train two operators and one fitter before sign-off; demand drawings, pneumatic diagrams, and password policy with the machine. Spare parts with lead time risk for mustard seeds lines include sealing jaws or Teflon, forming collars for each width, and filler-specific wear parts (auger flights, cups, weigher buckets, linear pans, wrap belts, or count sensors as applicable). Buying the cheapest film that ‘almost seals’ at 120–150°C usually raises scrap more than the reel savings. Commercial comparison: use published prices for price transparency, then insist on trials with your mustard seeds and your film. Numbers that decide the purchase are density, 28–36% seed oil if crushed, peel strength, giveaway or reject rate, and sustained packs per minute — not marketing adjectives. GST is extra on published tags; nitrogen, extra heads, and special MOC change the final configuration cost. For mustard seeds, revisit film COF if packs slip on inclined outfeeds; a 0.05 COF shift from a new reel lot can raise fall-over scrap without any machine fault. Operators packing mustard seeds should know the abort sequence for film break and hopper empty — untrained clears are a top source of bent jaws and cut fingers. Keep a scrap Pareto for mustard seeds with categories for seal, weight/count, and print; fund fixes for the tallest bar first. When ambient RH jumps 15–20 points, re-check the first 50 packs of mustard seeds before releasing the shift’s production. Align purchasing of film and spare collars for mustard seeds so a width change does not strand the line waiting for tooling. For mustard seeds, revisit film COF if packs slip on inclined outfeeds; a 0.05 COF shift from a new reel lot can raise fall-over scrap without any machine fault. Operators packing mustard seeds should know the abort sequence for film break and hopper empty — untrained clears are a top source of bent jaws and cut fingers. Mustard seed packing next to oil expellers needs dust and oil mist separation — mist on film destroys seals. Yellow versus black mustard densities differ slightly; recalibrate cups on seed type changes. For 1 kg agro packs, add handle-hole or easy-open features only after confirming they do not create leak paths at the punch.
