If the filters are dirty, replace them? If the inlet temperature is below that specified by the manufacturer, check to see if the heating element is operating properly.

Different resins require different drying times. Not all resins can be dried in 2-4 hours. This is especially true for resins with a low drying temperature or soft resins that can stick together if the drying temperature is<br \/>elevated.<\/p><p>c. <b>Leaks in the System<\/b> \u2013 The hopper and the conveying system need to be isolated from ambient and each other. Any leaks that can cause the dry air to leave the system should be eliminated. This is also true of hoses and ducting.<\/p><p>d. <b>Incorrect drying temperatures<\/b> \u2013 Try to follow the manufacturer\u2019s recommendations. For instance, not all grades of the same resin class should be dried at the same temperature. (i.e. not all nylon 66\u2019s<br \/>are the same) Also, are all of the elements in the process heater working? At<br \/>times, this can lead to lower than designed drying temperatures.<\/p><p>e. <b>Hopper Level <\/b>\u2013 Is the hopper level being controlled at too low a level for the residence time necessary?<\/p><p>f. <b>Dew Point Performance<\/b> \u2013 There must be a driving force for the resin\u2019s moisture to leave it for the air stream.

The hopper may be too small for the required residence time, since some resins need more than 2 to 4 hours, or the hopper level may be too low. Leaks in the hopper, hoses, or conveying lines let dry air escape. Confirm the drying temperature matches the manufacturer&#8217;s recommendation for that grade, the heater elements are working, and the wheel turns at the specified speed.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-29ec37b elementor-widget elementor-widget-heading\" data-id=\"29ec37b\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\">Why does resin melt or get tacky in the drying hopper?<\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-3f226b2 elementor-widget elementor-widget-text-editor\" data-id=\"3f226b2\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Usually the drying temperature is too high. Air picks up heat across the process blower and across the desiccant, so most dryers have a minimum operating temperature; cooling water before or after the desiccant may be needed to hit a low setpoint, common with copolyesters and bio-resins. High wheel speed shortens time in the cooling section and raises discharge temperature, and low airflow from dirty filters does the same.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7b7e609 elementor-widget elementor-widget-text-editor\" data-id=\"7b7e609\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<h2 style=\"font-family: inherit; font-weight: inherit;\">About the Authors<\/h2>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-0324a81 elementor-widget elementor-widget-shortcode\" data-id=\"0324a81\" data-element_type=\"widget\" data-widget_type=\"shortcode.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<div class=\"elementor-shortcode\">\t\t<div data-elementor-type=\"section\" data-elementor-id=\"5946\" class=\"elementor elementor-5946\" data-elementor-post-type=\"elementor_library\">\n\t\t\t<div class=\"elementor-element elementor-element-5ac2ce0 e-flex e-con-boxed e-con e-parent\" data-id=\"5ac2ce0\" data-element_type=\"container\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-b4853d4 elementor-widget elementor-widget-image\" data-id=\"b4853d4\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" width=\"150\" height=\"150\" src=\"https:\/\/www.novatec.com\/knowledge-center\/wp-content\/uploads\/2026\/09\/mark-haynie-studio-150x150.png\" class=\"attachment-thumbnail size-thumbnail wp-image-5924\" alt=\"Mark Haynie, Novatec resin drying expert\" \/>\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-23e7ff1 e-con-full e-flex e-con e-child\" data-id=\"23e7ff1\" data-element_type=\"container\">\n\t\t\t\t<div class=\"elementor-element elementor-element-04137fe elementor-widget elementor-widget-heading\" data-id=\"04137fe\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h3 class=\"elementor-heading-title elementor-size-default\"><a href=\"https:\/\/www.novatec.com\/knowledge-center\/novatec-expert-author-panel\/#mark-haynie\">Mark Haynie<\/a><\/h3>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4d7dfce elementor-widget elementor-widget-heading\" data-id=\"4d7dfce\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Vice President of Moisture &amp; Drying Technologies, Novatec<\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-4f9ecb7 elementor-widget elementor-widget-text-editor\" data-id=\"4f9ecb7\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Mark Haynie has designed and installed resin drying systems for more than 40 years, working in thousands of plastics plants across the industry.
