High accuracy feeder

Product catalog summary

Introduction
The document discusses the Fine Dosing FD SP A – 0808, a high-accuracy micro feeder developed by M.C.P.I. SAS. It highlights the feeder's precision, efficiency, and adaptability, making it suitable for industries requiring meticulous dosing, such as pharmaceuticals and food processing.

Specifications
The Opti-feeder FD-SPA is available in two classes: A Class with a resolution of 0.01 g and AAA Class with a resolution of 0.001 g. The feeders are designed to achieve high accuracy with a standard deviation ranging from 0.005 g to 0.04 g, depending on application parameters. The minimum dosing time is 3 seconds, and the minimum set point is 0.07 g.

Design and Functionality
The feeders feature a swivelling bowl mounted on a precise load cell, with sensitive components like the motor reducer and scale housed in protective casings. The integrated batch controller manages coarse and fine feeding with automatic tolerance control, achieving a coarse/fine feeding ratio over 100 for fast and accurate dosing. The design complies with cleaning requirements for drug and food industries, allowing for quick dismantling and complete emptying.

Software and Data Management
Data can be transmitted and received via RS-232C between the weighing instrument and a computer, allowing for display, saving, and printing of results.

Performance Results
Test results for various ingredients show the feeder's capability to handle different materials with varying set points and dosing times, maintaining low standard deviations. For example, tomato seeds at a set point of 0.09 g have a dosing time of 5.5 seconds with a standard deviation of 0.02 g.

Applications
The FD SPA-A is used in various applications, including the dispensing of pyrotechnic powder and tablet fabrication, where it dispenses 1 gram every 5 seconds with a maximum standard deviation of 0.05 grams.

Cleaning and Maintenance
The feeder includes features like a cleaning position, powder extractor, and pneumatic device to reject inaccurate feedings, ensuring easy maintenance and reliability.

Catalog excerpts

Micro feeders SPA are probably the first on the market to reach such levels of excellence in term of accuracy, short dosing time and flexibility. The ingredient is dosed in a small swivelling bowl fitted on an accurate load cell. Sensitive parts as motor reducer and scale are installed in a protective casing. The integrated batch controller optimizes coarse and fine feeding with automatic tolerance control. concept allows a ratio between coarse/ fine feeding over 100. This figure is a key point to reach fast dosing process and accuracy. In automatic version, feeding is made in a weighed bowl, at the end of dosing stage the bowl rotate 360. The ingredient is then emptied to the application point. The ingredient can be, as well, feed directly in the final container or box, positioned (manually or automatically) on the scale. Design of these feeders is made in agreement with drug and food industries requests for cleaning. Rotation of weighed bowl with 2 combined movements (for a perfect emptying). > __________ FD SP A Ж 0808 ___________ M.C.P.I. - SAS > Rue des Cols Verts - BP 1013 - 74966 MEYTHET Cedex FranceTel : (33) 04.50.33.90.20 - Fax : (33) 04.50.10.12.96
