The drop height between the scale and the filling hopper determines the percentage of broken beans: Short transfer sections and curved drop tubes keep the percentage of broken beans low.<\/p>\n<h2>Flavor Preservation: Valve, Film, and Gas Flushing<\/h2>\n<p>Three elements ensure the flavor:<\/p>\n<ul>\n<li><strong>One-way degassing valve:<\/strong> Freshly roasted beans release carbon dioxide for up to several days. The valve lets CO\u2082 out but doesn't let oxygen in\u2014without the valve, the bag would swell up.<\/li>\n<li><strong>Laminated film with a barrier layer:<\/strong> Protection from light and oxygen provided by an aluminum or EVOH core layer; an opaque outer layer protects the oils in the beans.<\/li>\n<li><strong>Nitrogen flushing:<\/strong> During sealing, N\u2082 flushes the bag and reduces the residual oxygen to below 2 %. Gas flushing is required for ground coffee and recommended for whole beans.<\/li>\n<\/ul>\n<p>The seal must be grease-resistant: coffee oils can damage the sealing strips. Easy-to-clean sealing strips and temperature-controlled sealing plates with a tolerance of \u00b15 \u00b0C are standard here.<\/p>\n<h2>Four-Step Selection Process<\/h2>\n<ol>\n<li><strong>Define product:<\/strong> Whole beans or ground? Fill weight: 250 g, 500 g, or 1 kg? Ground coffee requires a screw feeder and must be treated with gas\u2014a different dosing system than for whole beans.<\/li>\n<li><strong>Set the dosage:<\/strong> Multi-head scale for beans at a rate of approximately 30 bags per minute or more; for lower rates, a simpler weighing conveyor is sufficient.<\/li>\n<li><strong>Determine the bag size and film type:<\/strong> Stand-up pouches with valves require a different set of mold components than flat pouches; the film determines the sealing parameters.<\/li>\n<li><strong>Services and Surroundings:<\/strong> 30 to 60 bags per minute, depending on the scale; roller bearings and roastery dust require a SS304 stainless steel design.<\/li>\n<\/ol>\n<h2>What You Shouldn't Underestimate About Roasted Coffee<\/h2>\n<p>Real-world data from project runs: Bean breakage increases with every bend in the product path\u2014transfer pieces cost less than rejected product. The valve must be compatible with the sealing process; otherwise, it will leak. And the recipe changes: Anyone who later adds ground coffee or coffee pods will need a machine that can be retrofitted with screw feeders. The question of retrofitability should be included in every inquiry.<\/p>\n<h2>When a VFFS Isn't Suitable for Coffee<\/h2>\n<p>For very small production runs of fewer than 20 pouches per minute and frequent product changes, a semi-automatic machine or vacuum packaging in cans is more cost-effective. VFFS is not suitable for pasteurized products or liquids (coffee concentrate)\u2014in these cases, a dedicated liquid packaging line is the best solution.<\/p>\n<h2>Frequently Asked Questions<\/h2>\n<h3>How many bags of coffee beans per minute is realistic?<\/h3>\n<p>The industry standard is 30 to 60 bags per minute using a 10-head scale. Product handling limits the cycle rate more than the machine itself: Above 60 cycles, the number of broken beans increases noticeably.<\/p>\n<h3>Does every package of coffee beans need a degassing valve?<\/h3>\n<p>For freshly roasted beans, yes\u2014they release carbon dioxide over the course of several days. For beans that have been stored longer (about three weeks or more after roasting), a tight-fitting plastic wrap without a vent is sufficient.<\/p>\n<h3>What kind of plastic wrap is commonly used for coffee beans?<\/h3>\n<p>An opaque laminated film with a barrier layer to retain aroma, often PET\/AL\/PE or PET\/EVOH\/PE. Key factors are an oxygen transmission rate of less than 1 cm\u00b3\/m\u00b2 per day and the sealability of the inner layer.<\/p>\n<h3>Can ground coffee be dispensed using the same machine?<\/h3>\n<p>Yes, if the machine can accommodate a screw feeder. The ground material is dispensed volumetrically via the screw and absolutely requires nitrogen flushing\u2014the changeover involves a change in the dispensing method plus a change in the recipe, not a change in the format part.<\/p>\n<p><strong>Related pages:<\/strong> <a href=\"https:\/\/lintyco.de\/en\/was-ist-eine-vertikale-schlauchbeutelmaschine\/\">What is a vertical form-fill-seal (VFFS) machine?<\/a> | <a href=\"https:\/\/lintyco.de\/en\/was-ist-eine-mehrkopfwaage\/\">What is a multihead weigher?<\/a> | <a href=\"https:\/\/lintyco.de\/en\/kaffeeverpackungsmaschine\/\">Coffee Packaging Machine<\/a><\/p>\n<hr>\n<p>Request technical specifications and a quote for your production line.
