Processing technology is the core issue of Modern rice processing plant

If processing equipment and processing lines are the muscles and torso of a rice processing plant, then processing technology is the soul; the only value of equipment and operating equipment is to achieve technological processing goals.

Before production and processing, the preset and desired process is the "target process"; and the actual effect after processing is the "actual process". In the current rice processing and production activities, the target technology and the actual processing technology are almost always inconsistent, especially in the unit time, the actual processing technology effect is always fluctuating and fluctuating. Some processing companies do not even make clear Some of the target processes of the production and processing are only passive after the end of the production and processing, and the production and processing activities have completely lost the clear control of the goals they should have, let alone setting.

Each process of rice processing will produce a corresponding process effect. The accumulation of process effects of each process is the final process result. The final process results are embodied as: rice yield rate, whole rice rate, processing precision (skin retention rate, embryo retention rate, whiteness value, transparency), broken rice rate, heterochromatic grain rate, etc.

The process effects of each process are independent and related to each other. For example, the process effect of removing impurities and removing stones directly affects the hulling process: if removing impurities and removing stones is not clean, the rubber roller is easy to wear and the hulling rate decreases; The effect not only directly affects the rice yield, but also directly affects the brown rice hulling rate: too high the hulling rate will increase the hulling rate, and the hulling rate will increase the return to the hull, and the increase of the return hulling will still increase the hulled and broken brown rice. The instability of the husking rate also makes the grain separation effect poor. There are more grains in the grain, which affects the rice milling effect. The grains in the grain are more rough, which increases the number of re-husked grains, which not only reduces the output and increases the energy consumption, but also makes the grains hulled. The crushing is further increased; modern rice milling process is the core and most critical process of rice processing, and the effect of grain separation directly affects the effect of rice milling: the first milling process determines the initial stage of the second milling, and the second milling process determines the incoming material for the third milling. ..... By analogy, one link is closely linked, and a slight deviation in any link will affect the final processing technology effect, affect the rice output rate, affect the quality of the finished rice, affect sales, affect word-of-mouth, and affect Corporate profits.

At present, the actual processing technology of the rice mill is almost out of touch with the target technology, not only does not match, but also irregularly. The degree or level of the inconsistency changes irregularly over time, so it is easy It is understood that the processing quality of rice mills is usually unstable: satisfactory processing results cannot be sustained, maintained, or reproduced, and unsatisfactory processing results cannot be eliminated, unavoidable, and unavoidable.

The actual processing effect is unstable, which makes the quality of the final product unstable; there is no standardized and executable target process for each process, so that the process effect cannot be reproduced every time.

This phenomenon is usually considered to be the result of changes in raw grains, but this is not the case, but because the rice processing technology has not been standardized, lean, and stabilized. This is easy to verify and judge. If the hulling rate of the rice hulling machine has been stable at a certain value, under the condition that the equipment is not malfunctioning, there will be basically no deviation in the process effect of the brown rice, and there will be no deviation in the brown rice. There will be no brown rice in the rice hulling; if each rice milling process can be uniform and meet the technological goals, the final rice milling quality will not be unstable, and it can be uniform, up to standard, and not redundant.

Then, how to achieve process standardization has become a key issue.

First of all, it is necessary to establish a set of process goals, which can be qualitative and quantifiable. The corresponding process standards are established step by step, from cleaning, removing stones, hulling, and separating rice to rice milling, rice polishing, rice color sorting(rice color sorter machine price), and rice blending. When establishing standards, some processes are easy to qualitative, such as hulling of hulled rice, what is rice, brown rice, what is broken brown rice, or unripe brown rice. People have natural instinctive identification standards, so the target process of hulling is only hulling. Quantification of the amount of brown rice and the amount of broken brown rice; some processes need to start with qualitative work, such as rice milling. At present, the process requirements for the rice milling process are different, some require whiteness, some require transparency, and some require Embryo retention rate or skin retention rate. At the same time, under the condition of multi-machine light grinding, it is also necessary to define each process of rice milling separately. However, this will face many problems: If the embryo retention rate or the skin retention rate is used as the final grinding standard, the first and second grinding cannot be defined by the embryo retention rate or the skin retention rate; if it is defined by the whiteness value or transparency, the uniformity problem cannot be identified. The standard itself Just "non-standard"-whether it is whiteness value or transparency, the current measurement method has inherent defects-for example, when measuring 10,000 rice grains (of course more or less), the whiteness value is 1 The overall presentation of 10,000 grains of rice (the measurement of transparency is the same), and which of these 10,000 grains of rice just meet the target process, which ones are lower than the target process (how much lower), and which ones are higher than the target process (high How many) are all unknown. Therefore, it is possible that the overall whiteness value or transparency of 10,000 meters is up to the standard. In fact, it is the 2000 that has just reached the standard. There are 4000 more than the target process, and the 4000 has not reached the standard. Target process.

Therefore, the standard establishment of the target process must be scientific, definable, quantifiable, and ensure the consistency of the standard. To implement the consistency of the standard, it is also necessary to ensure the only data source for the implementation of the standard.

Secondly, after having an enforceable standard, the key lies in the means to implement the standard. The means to implement the standards include methods and methods, as well as who implements them and how to implement them. The first problem we face here is sampling. The representativeness of the sample is very important. The sample is not representative. Everything is in vain. The solution The only way is "online testing". "Online testing" is not a batch of samples obtained online, but must be samples that truly represent "online", and it must also be a steady stream of samples and a steady stream of testing. The second problem is to detect the subject, that is, "who performs it". If the result of the execution will change with the environment or time or subject, then no matter how good the standard is, it will not help. For example, under the influence of light, under incandescent lamp There is a difference between the test under fluorescent light, the difference between the morning and the evening, or the sensory evaluation that can be affected by factors such as mood, physical condition, and willingness to work, or different people have different test results (the so-called "100 people reading "One hundred Hamlet", Zhang San said it was white enough, Li Si felt that it was not enough; Zhang San felt that the transparency was just right, Li Si felt that the transparency was slightly insufficient)... All of these are contrary to the standard itself, and the subject of the implementation of the standard is subjective The composition and implementation results will inevitably be erratic, so standard implementation must be the "only" source of data.

Thirdly, it lies in how to implement the process standards. For example, the target process for hulling is 87%. Then: First, we must accurately understand the current (the "current" of each unit of time, that is, "real-time". The dimensionality is continuous) What is the hulling rate, not "approximately", nor "feeling", but the only standard test; second, refined hulling machine modulation, from the continuous hulling process The data is continuously analyzed and judged, and deviations are discovered and repaired immediately. Another example is rice milling. If the target process of a milling process is 65% roughness, then it is necessary to accurately perform the actual process effect of 65% roughness and always maintain stable.

Each process has a standard target processing technology, and has been lean execution, standard and fine processing process control, to ensure the stability of the final process effect, but also to ensure that any process goal is not only achievable, And it can be reproduced repeatedly.

This is the standardization, lean and stabilization of rice processing technology. Standard, lean, and stable processing technology can process rice to any desired precision, and can also greatly reduce the loss of rice processing, or even minimize it.
