The DA 7440 On-Line Analyzer delivers continuous, non-contact measurement of key quality parameters directly on the conveyor belt. By monitoring product in real time, it eliminates testing blind spots and enables food manufacturers to reduce waste, tighten quality control, and improve margins.
Benefits & Features
Real-time, non-contact measurements Robust diode array technology delivers 50 spectra per second without touching or disrupting product flow. Air-purge window ensures contamination-free measurements for immediate process adjustments and yield optimization.
Proven calibration library with direct transfer capability Direct calibration transferability from DA Benchtop Analyzers to On-Line Analyzer reduces implementation time and ensures consistency between lab and production measurements.
Flexible configurations for diverse environments Available in general-purpose (IP65/IP67), sanitary design (IP69K), and actively-cooled versions for environments up to 70°C. ATEX version for use in ATEX/IECEx zones 21/22 enables safe installation in dust-explosive atmospheres.
Operator-friendly monitoring High-visibility color-coded indicators display status and alarm conditions at a glance.
Industry 4.0 ready Web-based ProcessPlus software runs on PC, server, or virtual machine with Ethernet connectivity for remote monitoring and data accessibility
IoT-compatible communication Industry-standard protocols including OPC UA, PROFINET, Modbus TCP, Profibus DP, Modbus ASCII, analog outputs, and SQL queries enable straightforward integration with existing plant systems.
Applications
Calibrations to serve multiple markets
Backed by Perten's extensive calibration library and expertise, the DA 7440 delivers versatile over-the-belt monitoring across diverse food and industrial processing environments. Suitable for measuring cookies, crackers, extruded products, flakes, granules, pellets, blocks, shreds, and other solid products transported on conveyor belts for moisture, fat, protein, sugars, starch, fiber, and other quality parameters.
Some key markets include:
Grain-Based Foods & Bakery Monitor moisture, and fat in cookies, crackers, pasta, noodles, and breakfast cereals to control baking, frying, and drying processes.
Snack Food Production Measure moisture, fat, and seasoning in potato chips, extruded snacks, and corn products to optimize frying and maintain consistent flavor and texture.
Feed & Pet Food Manufacturing Control moisture and fat in pelletized products. Monitor water activity to prevent mold growth and optimize cooling processes.
Dairy Processing Measure fat, moisture, and protein in cheese blocks, shredded cheese, and butter to minimize waste during grade changeovers and ensure specification compliance.
Confectionery Production Monitor moisture and fat in chocolate, candy bars, and confections to control tempering and ensure consistent product quality.
Processed Meats & Poultry Measure moisture, fat, and protein in formed patties, nuggets, and processed products to ensure specification compliance and labeling accuracy.
Oilseed Processing Measure moisture and protein in meals and press cakes post-extraction to optimize drying operations and maximize product value.
