New process of BB fertilizer production

New Process of BB Fertilizer Production Zhang Zhu (Qinhuangdao Space-Time Science and Technology Development Co., Ltd. 0335-7951932) Abstract: This article analyzes the phenomenon of material shunting, that is, product quality instability due to the difference in material density and particle size in the current BB fertilizer production. A new process for the production of BB fertilizers was proposed - a new process with a single bag of quantitative ingredients, mixing and packaging. According to the characteristics of the new process, a new integrated equipment for BB fertilizer production was developed and developed. The equipment has proved through many years of production practice: the equipment runs smoothly, the dosing precision is high, and the product quality is stable. It has the advantages of less investment, low production cost and high production efficiency. Key words: ingredients, mixing, packaging Prospects for the development of BB fertilizer BB fertilizer is a new type of fertilizer developed in China in the 1980s. It indicates that China's agricultural fertilization and fertilizer production have entered a new stage and level. With the continuous development of agricultural production, farmers have also continuously improved the level of scientific farming and scientific fertilization. They have become more and more aware of the profound meaning of “to produce large quantities, relying solely on fertilizers as their home”, and thus the concept and level of fertilization. It is also constantly changing and developing. From single nutrient-rich fertilizers to multiple nutrient-rich fertilizers, from the single application of phosphate fertilizers and nitrogen fertilizers to the application of compound fertilizers containing nitrogen, phosphorus and potassium nutrients, a gradual transition from the application of low-concentration fertilizers to the pursuit of high application concentrations Multi-complex fertilizer. In the past, the era of “relying on high yields and relying on old diammonium in the United States” has come to an end. With the increase in the level of scientific fertilization in our country, the output of grain has jumped once again, from the past two to three hundred pounds per mu. What a leap in leapfrogging this leap is, if there is no improvement in the level of scientific fertilization, how unthinkable it is. Today, with the rapid development of our national economy, all walks of life are pursuing high efficiency and low consumption, and agriculture is no exception. In the past two years, the information on the agricultural resources markets in various regions has told us that farmers are hoping and calling for us to produce for them. Nutrient high-concentration BB fertilizer (45%, 50%, 55%). This shows that farmers not only recognize the BB fertilizer, and in the pursuit of high-concentration BB fertilizer, that high-concentration BB fertilizer is low-yield and high-yield fertilizer. BB fertilizer is a kind of fertilizer with different processing methods in compound fertilizers. BB fertilizer has been developed in parallel with other compound fertilizer varieties. However, due to the low production level in the past, the development speed is slow, and the annual production only accounts for the production of compound fertilizers. The total amount of 15%, while in the United States BB fertilizer production and sales accounted for about 85% of production fertilizer. This gives us an inspiration. The BB fertilizer market has a lot of potential space in our country. In the past two years, with the upgrading of high-concentration compound fertilizers, the production of such high-concentration high-concentration compound fertilizers (45%, 50%, and 55%) using a granulation process is bound to result in new granulation and drying processes. The intractable technical problems will inevitably lead to high energy consumption, low efficiency, and high costs of production, which will inevitably make it increasingly disadvantageous in the market competition for high-concentration fertilizers. The production of BB fertilizer is just the opposite. Compared with the production of low-concentration compound fertilizers, the production and processing costs of high-concentration BB fertilizers will not only not increase, but will decrease accordingly. Therefore, it will inevitably occupy certain advantages in the competition of the compound fertilizer market. . It is not difficult to see that this increasing demand for high-concentration compound fertilizers has brought new opportunities for the development of BB fertilizer production. In addition, due to the simple process of BB fertilizer production, it is also more suitable for the production of variable-formula fertilizers and various special fertilizers that change at any time. In addition, China has invested a lot of manpower and financial resources for the development of the fertilizer industry in recent years. Several sets of production equipment for large-particle urea and granular potassium fertilizers have been put into production. This also provides quality assurance and raw material guarantee for the production of BB fertilizer in the future. Therefore, the production and market prospects of BB fertilizer are good. 2. Production Status of BB Fertilizer At present, China's BB fertilizer production currently can be divided into two major categories: one is intermittent; the other is continuous (as shown). Intermittent computerized batching - Upgrading - Intermittent mixing - Upgrading - Bag counting - Packaging (interrupted) Continuous computer batching - Upgrading - Roller mixing - Upgrading - Bag counting - Packaging (Continuous) But in either form they have a common drawback, and it is also a fatal flaw affecting the development of BB fertilizer - in the process of repeated upgrading of materials and sub-bagging measurement, due to the different proportions of the material and particle size, Caused the segregation of the material. The ingredients may be completely accurate and the mix is ​​completely uniform. However, due to the different materials in the lifting process, due to the different density and particle size of different materials, the different line speeds will result in the grading of the material flow, which will eventually result in imbalance of the nutrient content of the finished product fertilizer, not only causing the product quality to be unqualified. It also seriously affected the effectiveness of fertilizers. But at present, BB fertilizer production still only stays in the BB fertilizer production and shaping equipment and equipment formed by these two kinds of technological processes. There are many companies that even adopt primary workshop-style production methods such as pound weighing, mixing with cement mixers, manual bagging, and portable sewing, which are in sharp contrast with the current development of the fertilizer industry and the requirements of agricultural production. It does not adapt. 3. New Production Process of BB Fertilizer In view of the shortcomings and shortcomings in the current production of BB fertilizer, Qinhuangdao Time-Space Technology Development Co., Ltd. proposed a new production process for BB fertilizer and developed an integrated production device. That is a single bag quantitative ingredients, mixing, packaging new technology (Figure 3). Single bag ingredients - single bag mixing - packaging This process uses a single bag quantitative ingredients, mixing and packaging in one, simplify the process flow; shorten the movement of the mixed material, which reduces or overcome the material in operation The phenomenon of shunting has improved the product qualification rate. Due to the shortening of the process flow and the use of fully automated integrated production equipment, this has greatly increased the production efficiency and reduced the consumption, that is, reduced the production cost, which is the development of BB fertilizer. And market development has brought about a favorable space. Compared with traditional BB fertilizer production, this new process has the following obvious advantages: 1) Less investment Because the new process uses less than two lifting and one bag weighing scale than the traditional process. It is also suggested that the equipment be placed underground, so the new process does not impose strict requirements on the plant. 2) Ingredients have high precision Because the new process does not have the process of repeated feeding and sub-bag measurement, it integrates single-bag mixing, mixing and packaging to avoid material diversion, and overcomes the ratio of products to the product due to the difference in the proportion of materials and grain size. The impact of accuracy. Guarantee the accuracy of the single bag, also guarantee the quality of each bag. 3) Low production cost (take an annual output of 100,000 tons as an example) a) Low nutrient content loss: In order to ensure the qualified rate of products and take into account the instability of production, most manufacturers generally require nutrient content in the production process. Based on an increase of about 1 nutrient, if a nutrient content of 50 yuan / ton is calculated, one year production of 100,000 tons BB fertilizer, at least 5 million will be wasted. The new process does not need to increase the content or the content of the nutrient content on the basis of the provisions to guarantee the qualified rate of the market spot checks. b) Low power consumption: The total power of the new production process is about 8 kilowatts. The total power of the old craft is about 45 kilowatts. c) Low maintenance costs: Since the new process saves about 30% of the equipment compared to the old process. Therefore, maintenance costs will also be greatly reduced. 4) High production efficiency The new process saves a lot of equipment. As a result, the failure rate of the entire system in the production process is reduced, and the production efficiency is improved. In a word, Qinhuangdao Space-time Technology Development Co., Ltd. develops and develops an integrated equipment for automatic batching, mixing and packaging according to the new process flow, which not only improves the production efficiency and reduces the production cost, but also ensures the product quality and improves the economic benefits for the company. It also creates incalculable social benefits for agricultural development. 4. Concluding remarks Although China's current consumption of BB fertilizer is still not very large, but with the increase of BB fertilizer production process. More farmers will recognize the quality of BB fertilizers, and more manufacturers will see its potential profits. I think that when China's BB fertilizer consumption accounts for 50% of the total amount of fertilizer, China's agriculture will be a qualitative leap compared to the present.

Single Packed Yellow Waxy Corn Cob

For the most common waxy and sweet corn on the market, waxy corn has a higher nutrient content than regular corn, containing 70-75% starch (and almost all straight-chain starch), more than 10% protein, 4-5% fat and 2% multivitamins, with more grains, VA, VB1 and VB2 in protein than rice, with the highest fat and VB2 content. Yellow maize also contains carotenoids, such as rice and wheat. The molecular weight of waxy maize starch is more than 10 times smaller than that of ordinary maize, and the starch makes glutinous rice sticky and soft, softer than ordinary hard maize. It is more than 20% more digestible to eat than regular maize and it is suitable for people with less than perfect teeth. At the same time, it is not suitable for diabetics because of the very high content of straight-chain starch (a polysaccharide).

Waxy maize is also known as sticky maize. The grain has coarse, waxy endosperm, similar to shiny, glassy (clear) grains such as hard and dent maize. Its chemical and physical characteristics are controlled by a recessive gene, which is located on chromosome 9. 100% of the starch in the endosperm is straight-chain starch.
