How to judge corn moisture sensory? How to test corn moisture

Taking 14% moisture as an example, for each increase in moisture in corn, the metabolic energy of pigs is reduced by about 40kcal kg. In autumn and winter, there is a common problem of high moisture in corn, which will affect the production performance of livestock and poultry, and if it is stored improperly, it will lead to mildew and deterioration, which will bring poison and even death to livestock and poultry. In the face of thousands of households of corn, pig farms should not only pay attention to the mildew of corn when choosing to buy, but also strictly grasp the moisture.

So, how to identify the moisture content of corn? 1. Sensory Method.

Through some simple corn sensory detection methods, that is, through the objective sensation generated by the contact of "eyes, ears, mouth, nose and hands", the moisture of corn can be quickly and effectively determined, as follows:

One look: the more fine lines on the top of the corn kernels, the drier.

Second, grasp: Grasp a handful and hold it tightly, and the corn that overflows more is drier. Three bites: The sound is crisp when biting the teeth, and the corn of the bars is drier.

Four look again: the germ is dry, dry white, transverse into a crushed powder, indicating that the moisture is about 13.

Five pinching: pinch the concave edges on both sides of the upper part of the corn germ with fingernails: a slight trace, indicating that the moisture is about 14: if the traces are large and there is a broken skin, the moisture is about 15: if the upper end of the corn germ is soft and the grain color is dark, the moisture is about 16

Under normal circumstances, the moisture of dry corn kernels is 15 18, and the seeds will be mildew in a short period of time when the moisture of corn kernels exceeds 18, and the moisture of corn kernels that can be seen is less than 18%.

If it is to be used as a seed, the moisture of the hybrid corn kernel should be stricter, in the south, the moisture of the corn seed is less than 13, in the north is less than 15.

If the corn moisture that has just been broken from the ground is not easy to determine, because the moisture content of the fresh pure substance is different from 20 to 30 due to the different varieties of corn, some individual varieties may be outside the range of this value, so under normal circumstances, the corn will be dried and threshed, so that it is easy to preserve, in addition, when the moisture is below 18, the damage to the corn germ will be relatively small.

Under normal circumstances, the moisture of dry corn kernels is 15 18, and the seeds will be mildew in a short period of time when the moisture of corn kernels exceeds 18, and the moisture of corn kernels that can be seen is less than 18%.

Under normal circumstances, the moisture content of dry corn kernels is 15 18, and the moisture content of corn kernels is more than 18 when the seeds will mildew in a short period of time, and the moisture content of the corn kernels that we can usually see is less than 18%, if it is to be used to make seeds, the moisture content of the hybrid corn kernels should be stricter, in the south, the moisture content of corn seeds is less than 13, and the moisture content of corn seeds is less than 15 in the north. If the moisture of the corn just broken from the ground is not easy to determine, because the moisture content of the fresh material is different from 20 to 30 due to the different varieties of corn, some individual varieties may be outside the range of this value, so under normal circumstances, the corn will be dried and threshed, so that it is easy to preserve, in addition, the damage to the corn germ will be relatively small when the moisture is below 18.

To measure the moisture of corn, you can use a plug-in moisture analyzer.

Insert the instrument's sensor head into the corn pile or the corn bag together with the pole, and the moisture analyzer display automatically displays the water content. Easy to use and quick to measure.

You can also weigh a certain quality of corn first, then dry, and then weigh the quality of the dried corn, and calculate the moisture of the corn.

The moisture of corn can be detected by SFY-60E rapid moisture analyzer, the test time only takes 3 minutes, and it is fully automatic and uses all major grain depots without any consumables.

To measure the moisture content of corn is to measure the moisture content of corn.

1. The method of measuring the moisture content of corn is generally to take a certain quality of corn samples, weigh the amount, record its quality, and then weigh its quality after drying, record, record the quality recorded before drying minus the quality recorded after drying, which is the quality of corn moisture, and the percentage of corn water content in the corn mass before drying is the moisture content of corn.

2. There are moisture testers on the market now, and the use of moisture testers is time-saving and convenient and accurate.

3. It is very important to measure the moisture content of corn, before corn storage, it is necessary to measure the moisture content of corn, and the corn with high moisture content is easy to mold and deteriorate.

As a warehouse, the standard is 13%, the most copy is not more than 14%, the natural water is generally 15%-17% (since Du Ran dried), the traditional method is to use 105 oven to do moisture detection, but this method is more cumbersome, it takes too long (4h), the current market is more recognized is the rapid determination method of Guanya moisture, according to the principle of oven method successfully developed, a few minutes can detect the moisture content of corn, Whether it is acquisition or deep processing, it is more convenient and practical, the key is that the market recognition is relatively high, the Northeast grain depot, CCTV news broadcast are Guanya moisture meter.

The basic principle of the book is to weigh the corn, then dry, and then weigh, the weight difference before and after drying is the weight of the moisture, and then divide the weight of the moisture by the weight before drying is the moisture of the corn. Quietly.

The equipment available is a banquet dregs:

1. Oven, set the temperature of the oven to 105 degrees, bake for 4 hours, and weigh the weight of corn by yourself;

2. Infrared moisture analyzer: infrared lamp dries for 40 minutes, and weighs the weight of corn by itself;

3. Halogen rapid moisture analyzer: put the sample in, and it can be automatically dried, weighed, and calculated in ten minutes, and the reading can be done directly.

The basic principle is to weigh the corn, then dry it, and then weigh it, the weight difference before and after drying is the weight of the moisture, and then divide the weight of the moisture by the weight before drying is the moisture of the corn.

The available equipment is: Xingye Han.

1. Oven, set the temperature of the oven to 105 degrees, bake for 4 hours, and weigh the weight of corn by yourself;

2. Infrared moisture analyzer: infrared lamp dries for 40 minutes, and weighs the weight of corn by itself;

3. Halogen rapid moisture analyzer: put the sample in, and it can be dried by spinaching in ten minutes, weighing, and calculating, and it can be read directly.

Visual inspection is not possible, it must be measured and said with data:

Under normal circumstances, the moisture content of dry corn kernels is 15 18, and the moisture content of corn kernels is more than 18 when the seeds will mildew in a short period of time, and the moisture content of the corn kernels that we can usually see is less than 18%, if it is to be used to make seeds, the moisture content of the hybrid corn kernels should be stricter, in the south, the moisture content of corn seeds is less than 13, and the moisture content of corn seeds is less than 15 in the north. If the moisture of the corn just broken from the ground is not easy to determine, because the moisture content of the fresh material is different from 20 to 30 due to the different varieties of corn, some individual varieties may be outside the range of this value, so under normal circumstances, the corn will be dried and threshed, so that it is easy to preserve, in addition, the damage to the corn germ will be relatively small when the moisture is below 18.

To see how much moisture is not convincing to the corn, the key is to test the data.

Guanya SFY-6LS corn moisture analyzer, 3 5 minutes rapid detection.

Corn moisture content, if only look at the experience, hand touch and other experience of corn moisture has a large error, objectively want to know the corn moisture content, it is best to use instrumental analysis and detection.

The traditional moisture detection oven 105, it takes 4h or even longer, the intermediate process is cumbersome, it needs to be calculated and weighed, it is more troublesome, the faster on the market is to use the rapid moisture detection method of Guanya moisture meter company, the customer recognition is high, CCTV news has broadcast, whether you are receiving grain or grain depot detection, Guanya brand, corn grain moisture detector, 3 5 minutes detection fast.
