Bulk density is one of the comprehensive indicators reflecting the characteristics of grain, and it is also the main index for grading grain and evaluating the quality of grain technology at home and abroad [4]. According to the bulk density, the mass of a certain volume of grain piles and the required warehouse capacity of a certain quality of grain can be deduced, which has certain practical significance for the storage and transportation of grain [2]. In addition, bulk density is one of the important bases for calculating the theoretical flour yield of wheat [6].

Bulk density refers to the quality of grain and oil grains per unit volume. The grading of many grains such as wheat and corn in China is based on bulk density. The bulk density of the grain is determined by the size, shape, uniformity, depth of the groin, fullness, and endosperm texture [6].

Generally speaking, samples with mature and full grains, compact structure, small grains, and low water content have a larger bulk density [5]; Conversely, the bulk density is smaller [5]. In particular, the moisture content in the grain affects the bulk density, which generally shows a negative linear relationship, which is mainly due to the fact that the specific gravity of water is smaller than the specific gravity of the grain, and at the same time, the moisture also affects the volume of the grain, and the grain volume of grain with large moisture is also larger, and the mass in the unit volume is smaller [8].

Water is an important component of grain, which not only affects the change of grain grains, but also affects the processing, storage, and preparation of grain [1]. Grain with too high moisture is prone to heat and mildew, and an appropriate amount of moisture can ensure the smooth progress of grain processing and food production. There are two forms of moisture present in grains:

Free water and bound water. When the moisture of cereal grains reaches 14% 15%. [2] Free water begins to appear, and when the grain moisture is below, it is generally considered to be bound water [8].

Free water is very unstable in grain grains, and its existence is very unfavorable to the safe storage of grain, only when the water content of grain drops to the bound water range, grain grains can be dormant, [9] life activities can be reduced to a minimum, and it is conducive to grain storage [6].

In order to increase the stability of grain storage, the storage enterprises must take measures to reduce the moisture content of the high-moisture grain purchased. As the moisture decreases, so does the bulk density. Since bulk density is the grading index of wheat and is directly related to wheat, it is of great significance to study the relationship between moisture change and bulk density.

How to calibrate this grain moisture measuring instrument, or how to use it.

Hello! I'm Teacher Blood, and I'm sorting out the answers for you, so please wait.

Grain moisture meter commissioning steps:

Step: Turn on the machine and press the calibration button, put the weight, and calibrate automatically. Step 2: Take a sample, press the test button to start working.

Step 3: While the instrument is heating, the instrument is displaying the value of the lost moisture.

To name a few commonly used:

1. 7-inch LCD touch screen moisture meter operation (can detect grain moisture and grain yield at the same time):

1. Put the instrument on the flat test bench;

2. Then gently lift the heating cylinder and install the accessories;

3. Connect the power supply to turn on, the temperature resolution, and the instrument starts to self-test;

1. When measuring moisture, press the "display" button to display five parameter values such as "moisture indication value", "initial weight", "current weight", "test time" and "discrimination time".

2 Test: Press the test button, the heat lamp on the instrument lights up and starts to determine the moisture content in the sample. In order for the "test" button to be valid, the following three conditions must be met at the same time, one is that the instrument is working in the current weight state, the second is that the weighing value is greater than the gram, and the third is that the " " button has been pressed to make the instrument write down the initial weight.

Otherwise, the Test key is invalid. (See Figure 9).

3. Clear: In any state, press the "clear" button, and the instrument will automatically return to the "current weight" state. Similarly, when measuring the moisture state, press the "Clear" button, the instrument stops the moisture measurement and returns to the "current weight" state.

This calibration method of grain moisture measuring instrument is divided into:

There is a correction button in the function menu, which can be corrected;

There is a brother calibration button on the function menu button, and the sample calibration can be carried out according to the prompts;

Because this is a portable moisture meter, the test error is slightly larger, and the grain moisture meter that is commonly used at present is the heating method, which is accurate in testing, has multiple functions, and detects the grain rate at the same time;

Grain moisture detection is of great significance for grain purchase, processing, storage and transportation. In China, due to the imperfect means of moisture detection, a number of tens of billions of catties of grain are rotten and deteriorated in the process of storage and transportation due to high moisture content every year, and the loss is huge. Therefore, grain moisture has always been a very important quality indicator for the control of the food sector at home and abroad.

Grain moisture meter operation.

3. Standard method sampling;

4. Close the heating cylinder, and the instrument will be tested automatically.

5. The test time is about 5 minutes.

With the development of modern science and technology, more and more industrial equipment has been developed, which provides great convenience for people's life and work. As an efficient and convenient grain testing tool, handheld grain moisture measuring instrument plays an increasingly important role in agricultural production. But debugging this equipment is not so simple, let's share how to adjust the handheld grain moisture meter.

First of all, we need to prepare some simple posture tools, such as batteries, power cords, standard food samples, etc. After turning on the machine, enter the menu setting interface, select the calibration mode, and place the handheld grain moisture meter in the air for zero calibration. After calibration, the standard grain sample is placed into the measuring instrument for proportional calibration.

After calibration, the test can be performed.

Secondly, we need to pay more attention to how we use it. In the actual use process, we should aim the test head at the grain or seed, and ensure that the contact is good and not loose, so as to ensure the accuracy and accuracy of the data. At the same time, we need to pay attention to keeping the moisture meter in a dry and ventilated place to avoid the influence of water content as much as possible.

In addition to this, the instrument needs to be warmed up before the measurement to obtain the most accurate data for the volume.

Finally, as a precision instrument, we need to keep it clean and dry. After use, the test head and instrument surface should be cleaned and kept dry to avoid water beads affecting accuracy. In addition, the handheld grain moisture meter should be calibrated and maintained regularly to avoid excessive errors.

In general, through strict calibration, attention to the use method and reasonable maintenance, the handheld grain moisture meter will work more accurately and efficiently. It provides important technical support for the quality and precision of grain production, and also promotes the progress of agricultural science and technology in China.

Ensure the quality of food: The level of moisture content directly affects the quality and shelf life of food. Too much moisture will make the grain easy to mold and spoil, and too low moisture will make the grain dry, affecting the taste and nutritional value.

Therefore, measuring the moisture of the grain can ensure the quality and freshness of the grain and prevent spoilage and loss.

Rational use of resources: Grain with different water content requires different storage and transportation conditions. Measuring the moisture content of a grain allows you to understand its moisture content, so that you can take appropriate treatment and transportation methods according to different situations, avoiding waste and loss.

Ensure food safety: Food is one of the main foods in people's daily life, and its safety is directly related to people's health. Measuring the moisture of food can ensure that it meets the safety standards of the country or region, and prevent food contamination, deterioration and other problems caused by too high or too low moisture content.

Guiding agricultural production: Measuring food moisture can also provide guidance for agricultural production. By measuring the moisture content of grains at different growth stages, the growth and nutritional status of the crops can be determined, so as to adjust the planting management measures in time and improve the yield and quality of crops.

1. Grain moisture is an important indicator of grain storage, which is divided into safe grain, semi-safe grain, and dangerous grain according to moisture. Semi-safe grains and dangerous grains will heat up and mildew during storage, so it is necessary to control the moisture of the grain when it is delayed. Different moisture uses different storage and treatment methods.

2. Grain moisture is also a key indicator of grain quality, and the price of moisture is increased or decreased.

3. Grain moisture is an indicator in grain processing and an indicator to control the quality of processed products. For example, wheat needs a suitable moisture to produce high flour yield and high flour quality; Rice needs the right amount of moisture to ensure that the rice is crushed, the rice breaking rate is low, and the rice milling accuracy is high.

Grain water meter is a high-precision instrument that can measure the moisture content of materials. Its accurate and reliable measurements have redefined the standard for moisture testing in the food industry. However, for the first use, how to adjust the moisture content is a noteworthy issue.

Before using the grain water meter, the parameters of the measured object need to be set correctly. According to the different materials to be tested, the corresponding detection mode needs to be set. After the detection mode is determined, the sample is placed in the detection tray and the sample is placed in equilibrium, which is a state where the moisture content is relatively stable.

This is followed by a test to determine the moisture content of the sample.

When measuring, it is necessary to pay attention to factors such as the size of the sample, accurate weighing, and testing time to ensure the accuracy of the test results. When adjusting the moisture content of the sample, the moisture content should be appropriately adjusted according to the different material types and process characteristics of the ruler to avoid the degradation of quality caused by too high or too low water content.

In short, the use of grain water meter to detect the moisture content of materials is an important symbol of modern grain production. Rational use can improve the quality of products, help solve the problems existing in the production of enterprises, and establish a more credible and stable industry standard.
