A typical drying curve is shown at the right.

Section (A-B) represents the sample's weight loss as it heats from room to testing temperature.

Section (B-C) is linear, representing moisture loss from the interior of each particle of the tested sample.

Section (C-D) is exponential in nature

and represents the final evolution of moisture from within the particle. The point at which no additional weight loss occurs represents the complete evolution of water from the original sample (E).

Section (D-E) is the longest and most time-consuming portion of the entire testing process. The time for a sample to reach zero residual moisture in an oven can take from one to possibly 24 hours depending upon the sample, sample preparation, and testing temperature. The MAX 5000XL loss-on-drying system calculates the sample's moisture concentration through mathematical extrapolation from the exponential (C-D) portion of the curve.

An aluminum pan sits on a pan support coupled to a sensitive electronic force balance. The force balance registers the initial weight of the sample before testing and relays the sample's decreasing weight to the microprocessor for evaluation. Balance readings are averaged to eliminate signal interference or erroneous data.

Within each memory start, test temperatures can be programmed between normal room temperature (25º C) and 600º C in either a one-step or multi-step temperature contour. A heater is located on the underside of the test chamber's lid. An RTD monitors the temperature of the test chamber and sends that information back to the microprocessor. Under the microprocessor's control, the heater element is cycled on and off to bring the test chamber to the programmed level.

During the entire testing process, the microprocessor monitors the sample's weight loss. The sample's decreasing weight is compared to the initial sample weight and the calculated moisture concentration will appear on the display. Simultaneously, the microprocessor is predicting a final moisture concentration based upon the sample's rate of weight loss compared to the exponential portion of a standard drying curve. Testing will continue until the predicted moisture concentration agrees within a certain percentage of the actual moisture concentration appearing on the display. The percent agreement between the predicted and the actual moisture concentrations will vary depending upon the system's programming and the moisture level of the sample.

The MAX 5000XL is an extremely flexible instrument. This flexibility means that some time is required to determine the best set of parameters for a particular application. The determination of the proper parameters requires a series of tests, and good laboratory procedure. Call your AZI technical sales representative at 800-528-7411 or 602-470-1414 for assistance.

MAX-5000XL specifications

The Arizona MAX-5000XL is a premier flatbed printer designed for high-volume printing applications, renowned for its versatility and cutting-edge technology. This remarkable machine is part of the Arizona series from Océ, a brand recognized for its innovation in digital printing solutions. The MAX-5000XL is specifically engineered to deliver high-quality graphics across various substrates, making it a favorite among businesses in signage, graphics, and packaging industries.

One of the standout features of the MAX-5000XL is its expansive printing capacity. With a maximum bed size of 126 x 98 inches, it can accommodate large sheets, enabling the production of oversized prints without the need for cumbersome tiling or trimming. This feature not only saves time but also enhances operational efficiency, allowing businesses to streamline their workflow.

The MAX-5000XL employs advanced UV printing technology, which uses ultraviolet light to cure the ink instantly as it is printed. This results in vibrant colors, sharp details, and improved durability, making prints resistant to scratches, chemicals, and UV exposure. The printer’s ink system features highly pigmented inks that produce stunning images, offering a wide color gamut that is perfect for demanding graphical applications.

Moreover, the printer is equipped with a sophisticated high-resolution imaging system that delivers outstanding print quality at resolutions up to 1440 dpi. This level of detail ensures that even the finest elements of a design are replicated with precision. The machine also incorporates a variable dot technology that optimizes ink droplet size based on the image content, further enhancing the overall image quality.

Another notable characteristic of the Arizona MAX-5000XL is its user-friendly interface. The printer features intuitive software that simplifies setup, operation, and maintenance, enabling operators to focus more on production rather than troubleshooting. The machine also supports automated printing features, reducing manual intervention and helping to improve turnaround times.

In addition, the MAX-5000XL is designed with sustainability in mind. Its low-energy LED UV curing technology not only reduces energy consumption but also minimizes the environmental impact of the printing process. The ability to print on a wide range of substrates, including rigid and flexible materials, also expands the creative possibilities for designers while offering greater options for businesses looking to cater to diverse markets.

In summary, the Arizona MAX-5000XL is a state-of-the-art flatbed printer that combines large-format capabilities, exceptional print quality, and advanced technology. Its user-friendly features and emphasis on sustainability make it an ideal choice for businesses seeking to elevate their printing operations to new heights.
