Things to Consider Prior to Purchasing a Grain Moisture Tester

 What type of grain moisture tester is right for you?  There’s two kinds of grain moisture testers. A transportable or hand held tester is ideal for fast field assessments. A bench model, however, is much better fitted for evaluating grain that’s to become stored. A bench model obviously has more power, meaning it provides increased precision in determining appropriate moisture levels.

 Maintain battery health!  If you are employing a portable grain moisture tester, ensure that the battery is fully charged. A low battery may cause incorrect measurements. Throughout the long months while the tester is not being used, take out the battery to avoid leakage. The battery pack ought to be swapped out at least one time a year.

 Read the user guide!  Not many of us want to check the user guide, nevertheless, you should definitely examine and be aware of the maker’s recommendations, particularly the tester’s temperature compensation approach.

Tips on Operating a Moisture Tester

Moisture Meter Tips & Strategies
  • Grain temperature may have a large influence on moisture measurements. Some moisture testers have automatic temp compensation, while others compensate only after you press a control button, and others demand that you just calculate grain temperatures, and then add or subtract a correction factor to the reading.
  • Cold grain temperatures in most cases lead to low measurements, unless of course moisture has condensed on the exterior. With condensed surface moisture, digital testers in most cases provide higher readings. Cold grain ought to be warmed up inside a enclosed container prior to it being analyzed.
  • Should you test hot grain from the dryer, that may end up being challenging. Digital testers have a tendency to underestimate the moisture levels of hot or rapidly cooled grain. Grain also will lose moisture as it cools. To obtain the real moisture content of hot grain, allow it to cool gradually in a enclosed container prior to screening.
  • All grain moisture testers demonstrate some variation in measurement. Different measurements can be observed when the exact same sample is analyzed over and over again. As a result, you need to analyze each and every sample a minimum of 3 times and calcualte the average result.
  • Whenever carrying out your own personal test, it’s vital that you get yourself a representative grain sample to work with.

What Users Are Saying

  • Calibrations can be tricky and require repeated testing to gain familiarity with the readings the moisture detectors provide – so you will definitely need to become intimately familiar with the unit you ultimately decide to purchase. 
  • User manuals are incredibly important with these devices – also be sure to check out what sort of internet resources exist for the particular tester that you choose – particularly important is robust phone & email support. 
  • With portable readers, ballpark estimates are what customers commonly expect from the devices. These help to inform decisions on the fly – but continuous calibration is still very important. 

What is grain quality?

Grain quality refers to the quality of grain. It should be noted, however, that this definition will vary by the type of grain that is being examined. In general, grain quality is influenced by a variety of factors that include postharvest handling, transportation practices, growing practices, type and time of harvesting and storage management.

What are grains?

If a food is made from one of the following: oats, cornmeal, rice, barley or another type of cereal grain then it is a grain product. Grains are generally classified by whether they are whole grains or refined grains.grain moisture

Whole grains contain all of the grain kernel, which includes the bran, the endosperm as well as the germ. Some examples would include cracked wheat, oatmeal, brown rice, whole cornmeal and whole-wheat flour. Refined grains, on the other hand, are milled.

This process removes the bran and the germ. The milling process provides the grains a much finer texture, improving their shelf-life, however decreasing B vitamin content as well as iron and dietary fiber.

Common types of refined grain items include: white bread, white rice, as well as white flour.

Refined grains are typically enriched. What this means, is that some of the nutritional elements like the B vitamins including niacin, riboflavin and folic acid, as well as iron, are reintroduced after the processing.

What are the benefits of eating grains?

Consuming grains is essential to maintaining good health. Research has demonstrated that incorporating whole grains as a component of a complete nutritional plan will decrease the risk of certain illnesses.

What are some of the health benefits?

  • Whole grain consumption can decrease your risk of heart disease.
  • Whole grains contain fiber which can help to alleviate constipation.
  • Whole grains are also implicated in effective weight management strategies.
  • Another interesting aspect of grains is that grains that contain folate can help pregnant women decrease the chances of neural tube defects that can occur during fetal development.

What are common whole-grain ingredients?

Rolled oats, oatmeal, buckwheat, brown rice, whole wheat, whole rye, wild rice, whole-grain corn, whole-grain sorghum and popcorn are all examples of whole-grain ingredients.

Grains can be broken down into true cereal grains and pseudo-cereal grains. The true cereal grains are from a botanical family known as Poaceae. This family includes sorghum, rye, millet, corn, rice, oats, and wheat.

It should be noted, that within the aforementioned groups there are also some other varieties. The pseudo-cereal grains are not part of the same family. Many of these are not really grains at all, but in reality they’re actually seeds from different plant species that are external to the Poaceae family.

While they are not considered true grains, their nutritional value is actually quite similar to the true grains. A lot of times, these pseudo-cereals are used when companies make flatbreads, pasta as well as popular snack bars.

In all, grains are an important component of the human diet and grain moisture detectors are a crucial component of the production of quality grain.
