They contacted IKEUCHI to discuss suitable spray nozzles for the process.<\/p>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<h3 style=\"font-size: clamp(20px, 2vw, 30px);padding-left: 14px;margin-top: 0;margin-bottom: 0.8rem;border-left: 5px solid #0c9b6f\">Solutions Proposed by IKEUCHI<\/h3>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">Internal-mixing pneumatic spray nozzles, which mix compressed air and liquid inside the nozzle to atomize the liquid, are commonly used to achieve fine sprays. However, with <span style=\"font-weight:bold\">viscous melted chocolate, clogging inside the nozzle was a concern<\/span>.<br \/>\nIKEUCHI therefore selected the <span style=\"font-weight:bold\">clog-resistant <a href=\"https:\/\/www.dry-fog.com\/en\/products\/noz-pne-setojet\/\" style=\"color: #00a273\" target=\"_blank\" rel=\"noopener\">SETOJet<\/a> Series<\/span>\u2014an external-mixing pneumatic spray nozzle that mixes air and liquid outside the nozzle to reduce clogging.<\/p>\n<div style=\"text-align: center;margin-bottom: 10px\">\n<img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/03\/nozzle-food-020-image_3.jpg\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/>\n<\/div>\n<p style=\"margin: 10px 0 20px 0;text-align: center\">Clog-resistant SETOJet Series nozzle<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.dry-fog.com\/en\/wp-content\/uploads\/sites\/3\/2026\/03\/EN_nozzle-food-020-image_4R.jpg\" alt=\"\" width=\"820\" class=\"aligncenter size-full wp-image-6304\" \/><\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">In addition, the chocolate was recirculated, so seeds from the freeze-dried strawberries could enter the line and further increase the clogging risk. To address this, IKEUCHI specified a model with a <span style=\"font-weight:bold\">larger free passage diameter* (2.0 mm)<\/span>, allowing particles to pass through more easily.<\/p>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">*The free passage diameter refers to the narrowest part of the liquid flow path inside the nozzle, indicating the maximum particle size that can pass through without clogging. A larger value means particles are less likely to get trapped inside the nozzle, reducing the risk of clogging.\n<\/p>\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<div style=\"margin-top:5rem;margin-bottom:3rem;width:100%;border-bottom:1px solid #E9E9E9\"><\/div>\n<\/div>\n<div style=\"max-width:824px;margin-left:auto;margin-right:auto\">\n<h3 style=\"font-size: clamp(20px, 2vw, 30px);padding-left: 14px;margin-top: 0;margin-bottom: 0.8rem;border-left: 5px solid #0c9b6f\">Benefits Achieved<\/h3>\n<p style=\"list-style-type: disc;margin-left:1.2rem;font-size: 1rem;line-height:1.6rem\">By spraying atomized matcha chocolate using the SETOJet, the customer <span style=\"font-weight:bold\">achieved a uniform coating<\/span> on the dried strawberries.
