England, Britain and the UK – What’s the difference?

Brexit has generated a lot interest in what are the differences between the country of England, Great Britain and the United Kingdom.  The unattributed graphic below might help understanding the differences.

Sam Adams – More Than Just a Beer . Happy 4th of July!

Samuel Adams is a sometimes controversial figure in history in no doubt impacted the Revolutionary War.  He was much more than a beer.  He supplied the fire and brimstone to keep the rebellion moving forward.

Reverse Roll Coating Measurement

Reverse Roll Coaters have a metering and applicator roll. Often there are 3 or 4 roll configurations.  Coating is applied through the gap between the metering and applicator roll where the nip pressure and gap control the specific coat weight.  The applicator roll runs in reverse direction of the web transferring the coating onto the web.  Reverse Roll Coaters are capable of producing highly polished surfaces and are more expensive than some other coaters such as slot-die that can’t always achieve that level of polishing.  If a Converter operates a Reverse Roll Coater a Cross Direction Web Profile System is a good investment to maintain uniform coat weight on high end products.  The Guardian Cross Direction Web Profile System meets the application needs for film, foil and paper coat weight and moisture measurements on Reverse Roll and other coaters.

Sand Moisture Control

Sand Moisture Plant 061616Sand Moisture Control is important in the manufacturing and processing stages.  Giant sand piles may sit exposed to the weather rain or shine impacting the moisture content of the whole pile and external versus internal moisture profiles.  It rained for 3 days and yesterday it was hot bright sunshine, then the exterior is dryer than the interior.  Near Infrared Moisture Transmitters provide an immediate measurement of sand moisture on the belt.  The transmitter is mounted between 8 and 18” (200 – 450 mm) above the product with an air purge of 3 – 10 psig to keep the sight lens clean.  Large digital display, proportional analog output (4 – 20mA) and Ethernet communications are available.

Sand is sold by weight and specification, meaning that there is range of acceptable moisture level in the sand upon delivery.  If the sand moisture exceeds that moisture level it can be rejected or purchased at a significant discount.  If the sand moisture is lower than that specification the supplier is leaving money on the table by not adding water to increase the weight while still being in specification.

Sand moisture can be controlled by dryer temperature, throughput and re-moisturizing.  Dryer Temperature adjustment may be used if a known incoming run of sand is high in moisture.  As a practical process control option dryers have too slow a response time for minor variations that still need to be optimized to maximize efficiency (profit).  Dryer throughput is the best control parameter as it can increase or slow throughput through the dryer based on moisture.  When raw product is over dried or oven has over dried a moisture spray station may be triggered by the PLC.  Moisture is money for Sand Suppliers.  An upper level in-specification sand moisture allows End User to optimize for specific application and maximize profits for supplier.

Let’s Laminate

 

Lamination is essentially marrying two or more layers of materials together to obtain superior performance characteristics for specific product applications.   Near IR Transmitters are well established to measure moisture and coating thickness in the lamination process.  Cross Direction Web Profilers greatly assist in producing an even in-specification profile of adhesive thickness.  The resulting composite may be designed as a superior moisture or odor barrier, to highlight/protect appearance or gloss, reduce sound transmission, to increase strength or structural stability and many other applications.

Auto windscreens (windshields)  laminate two pieces of glass with a layer of PVB (polyvinylbutyral)  or other suitable polymer to prevent or minimize sharp glass shards from showering on driver and passengers on impact by wrapping the glass surfaces with the polymer.  Near IR can measure the film moisture and thickness.

Converting industries such as Tag, Tape & Labels, Packaging & Release Liners, Textiles and others operate Near IR to measure the adhesive coat weight applied and the moisture after unit operations such as dryers, re-moisturizers and final windup for QC and Process Control.  For converting applications a two roll laminator is often employed with one roll made of neoprene or other suitable rubber and the other roll made of steel or chrome plated.  The rubber roll applies pressure to the adhesive but also allows for compensation of caliper variations.  Nip roll pressure and skew assist in optimizing the process.

10 Step Near IR Calibration Procedure

Calibration Procedure for New Products

MCT Moisture Analyzer

 

This procedure is outlined for snack foods that may or may not be ground in the lab for analysis or powder and bulk solid or similar applications.  Double-Blind Samples are recommended for calibration and validation.  This allows the sensitivity or span (linear regression slope) to be accurately determined in the laboratory to speed up the calibration of on-line transmitter when it’s difficult to create a range of process moisture samples on-line.

 

 

Step 1: Collect sufficient product for about four or five samples of 200 grams each.

 

Step 2: Measure 100 grams +/- 2 grams and place into a sealed Bag or container.

This will be sample 1.

 

Step 3: Measure 100 grams and spray about 2 grams of water on the sample. Mix

the sample and place into a sealed bag or container. This will be sample 2.

 

Step 4: Measure 100 grams and spray about 4 grams of water on the sample. Mix

the sample and place into a sealed bag or container. This will be sample 3.

 

Step 5: Measure 100 grams and place in an oven with a temperature of 100 degrees C.

Leave this sample in the oven for 10 minutes*. Remove from the oven and

Place into a sealed Bag or Container. This will be Sample 4.

 

Note:   If a fifth sample is used repeat Step 5, but keep in oven for 20 minutes*.

 

Step 6: Leave these samples in the Sealed Bag or Container for at least four hours to equlibrate.

 

Step 7: Take Sample 1 and place under the MCT. Record the moisture measurement.

 

Step 8: Do the Normal Lab analysis for this sample. A Confection Oven or

Vacuum Oven is recommended.

 

Step 9: Repeat Steps 7 and 8 for the remaining samples. When all the samples are

Analyzed, we can begin the MCT Calibration Routine. This can either be performed

via the MCT Operator Interface panel or by using the PSC Viewer Suite software. Entering the    Lab vs. MCT Near Infrared Transmitter Data allows for a linear regression to be performed and    the new Span/Sensitivity (Linear Regression Slope) and Zero/Offset (Linear Regression Y-    Intercept) to automatically be generated for correct calibration.

 

Step 10:  Confirm calibration by collecting sample on-line within target set point values and only make a zero or offset adjustment based on double-blind lab sample.  Congratulations!
