Applications

Measure granules, pellets, powders, pastes, syrups, flakes, liquids and more. The most commonly measured parameters are moisture, protein, ash, fat/oil, fiber and starch.

Many options are available for mounting – all designed for specific uses and products. The DA 7300™ can be mounted on pipes, hoppers, conveyors, mixers, at the entrances of a product, at its outputs, before or after dryers, before packaging or at other critical points in the process.

The DA 7300™ is installed and used at many agri & food production sites worldwide. These are a few examples of its applications.

Flour Milling – Maximize flour extraction through accurate real-time ash measurements. Blend wheat and flour streams to reach target specifi cation. Optimize gluten addition.

Starch Production and Corn Milling – Cost and energy savings by monitoring and controlling the dryer, constant product quality and higher output by protein control loops and avoiding quality giveaways.

Oilseed Processing – Measure moisture, protein and oil in grain for pricing and binning. Monitor and optimize extraction and drying. Control moisture & fat in mixer. Higher productivity by increasing yield and avoiding faulty batches and rework. Control moisture loss in cooling and additions of molasses/oil.

Dairy Processing – Reduce energy costs when spray drying milk powder by monitoring product moisture in real-time. Minimize grade change-over time and reduce waste; monitor black particles. Optimize the fat /moisture content of butter. The DA 7300™ is USDA approved for installation in dairy processing plants.

Technology

No moving parts

Diode array technology is unique in the sense that it doesn't use any moving parts in the spectrometer. This greatly improves the stability of the instrument as there are no parts that can be worn out or misaligned. The result is an instrument which requires much less maintenance than when moving parts are used, as for example is the case with scanning monochromators.

1. A lamp illuminates the sample with white light. Some of the light is absorbed (depending on the composition of the sample) and the rest is reflected.
2. The light which is reflected hits a stationary grating, which separates the light by wavelength. Instead of white light, we now have a "rainbow".
3. Each wavelength is measured by a dedicated detector.

All wavelengths simultaneously

With diode array technology all wavelengths are measured simultaneously, as each wavelength has a dedicated detector. This is necessary in order to be able to analyze a moving sample. Using scanning monochromator technology or Spinning filter wheel, the spectrum is collected one wavelength at the time, and if the sample moves the picture will be blurred.

Line Source Wavelength stabilisation

In all optical systems, microscopic mechanical movements occur over time and with temperature changes. These small movements give rise to changes in the wavelength scale and alignment. In order to achieve long term stability, it is imperative to correct for any such changes dynamically. In the DA 7300™ On-line, this is done using a line source which brings the wavelength axis back to the starting point. The benefit with using a line source is that this emits light with peaks at certain wavelengths. The position of these peaks depend on the line source used and is constant with that material. This gives unsurpassed wavelength axis accuracy and long erm stability.

Dual lamp with automatic switch-over.

In order to avoid down-time and costly rush repair jobs, the system is fitted with dual lamps. Once the primary lamp reach the end of its working life, the second lamp is automatically put in to operation in a seamless transition.

Accessories for DA 7300™ In-line NIR

Mounting Panel Accessory

The mounting panel is an accessory to the DA 7300™ In-Line NIR analyser. This facilitates mounting on a vessel, a conveyor side or any other location where the instrument is viewing the product from the side. The panel mounts on a frame that is to be welded on to the side of the measurement chamber in question.

 

Features and Benefits

Easy installation:

Simply weld the frame on the vessel side and bolt the door with instrument on the frame.

Easy Cleaning:

In the event the instrument window requires cleaning, simply open the door and wipe the window.

Includes a blind panel:

In the event the instrument is to be removed, simply mount the blind panel and the production can continue without product spillage.

Stainless Steel Construction:

Durable and robust for long life.

Measurement Chamber 25t/h

The measurement Chamber 25t/h is suitable for installation in any grain processing process, such as a flour or feed mill. It presents the grains to the instrument in the reliable and repeatable way that is required for any NIR analyser, and ensures highly accurate and repeatable results.

 

Features and Benefits

Repeatable sample presentation:

Ensures highly accurate and repeatable results.

Easy Instrument Cleaning:

A view window on the side is easily removable for cleaning the instrument window without having to remove the instrument.

Manual Sampler:

A sliding sampler mechanism allows a manual sample to be taken. By pressing a button, the instrument readings corresponding to the sample is tagged in the database for future reference.

Non-Blockage design:

By design, the over-flow section can handle the entire product flow, ensuring there is no production interruption even if the measurement part is blocked.

Measurement Chamber 120t/h

The measurement Chamber 120t/h is suitable for installation in a grain silo or other grain intake. It presents the product to the instrument in the reliable and repeatable way that is required for any NIR analyser, and ensures highly accurate and repeatable results.

 

Features and Benefits

Repeatable sample presentation:

Ensures highly accurate and repeatable results.

Easy Instrument Cleaning:

A view window on the side is easily removable for cleaning the instrument window without having to remove the instrument.
