Coconut milk is a national kitchen staple \u2014 and in terms of packaging, it's one of the most demanding liquids: fats that separate if left standing, proteins that sour quickly, and a flavor that customers instantly recognize when it goes off. Four packaging lines serve four market segments, each requiring different machinery.<\/p>\n
The fundamentals of liquid filling \u2014 nozzles, viscosity, foaming \u2014 are described in Automatic liquid filling machine<\/a>; This article maps out the specific pathways for coconut products.<\/p>\n Santar is briefly heated at high temperatures, sterilized, and filled into aseptic cartons in a clean zone. This is the major supermarket brand channel. Highest capital investment, highest complexity (aseptic zone + carton forming) \u2014 territory of large contract manufacturers; most mid-sized producers purchase UHT co-packing services and focus their machinery on channels 2\u20134.<\/p>\n Coconut milk is pasteurized and hot-filled into formed PE bags: the heat kills microbes on the inner surface of the packaging simultaneously. Cold shelf life: 2\u20134 weeks. This is the fresh supermarket and wholesale market channel. Technical note: hot-filled products require seals, hoses, and temperature-indicating sensors \u2014 piston or gravity-pressure filling from\u2026 liquid filling machine<\/a> with temperature control; and homogenization before filling, otherwise the fat separates and customers complain of \u201clumpy coconut milk.\u201d.<\/p>\n Single-use sachets for pastries and one-serving dishes: a vertical form-fill-seal (VFFS) machine line for liquids forms, fills, and seals 30\u201360 sachets\/min. The liquid must be medium-viscosity (200 ml of evaporated thick coconut milk diluted just enough to flow well); the technical aspects are the same as Tomato sauce packaging machine<\/a> \u2014 Pulp products require large pistons and passages.<\/p>\n Spray-dried coconut cream with maltodextrin: powder sachets that customers dissolve themselves. Auger machine: 30\u201360 sachets per minute \u2014 worldwide. Automatic powder packaging machine<\/a>. Hygroscopic coconut milk powder (strongly absorbs moisture) \u2014 a barrier film and air-conditioned sealing zone are essential; otherwise the powder will harden in the sachet by the second month.<\/p>\nFour routes, four machines<\/h2>\n
1. Aseptic UHT carton \u2014 shelf life 6-12 months<\/h3>\n
2. PE bag \/ hot-fill pouch \u2014 75-85\u00b0C<\/h3>\n
3. 10-50 ml liquid sachet \u2014 VFFS liquid<\/h3>\n
4. Instant coconut milk powder 15-40 g \u2014 VFFS auger<\/h3>\n
