Analytical Report on the Investment Value of Vacuum Low Temperature Continuous Drying Technology Drying is not an independent process. Dehydration and drying are not purposes. The purpose is to adjust the quality of the material. Drying is one of the process units with relatively high energy consumption. Under the current environment where energy conservation and environmental protection are increasingly valued, different energy prices are becoming more reasonable, and users are increasingly demanding the quality of the material drying, vacuum drying at a low temperature Energy-saving, high-efficiency, green environmental protection, and good drying quality have brought about excellent development opportunities. Seizing and making full use of this opportunity requires the joint efforts of government departments, industry, and academia. Drying is an important unit operation in the chemical process, and it is also an important process in many other industrial processes. With the improvement of the people's production level and the rapid development of industry, agriculture, commerce, service industry and emerging industries, the application fields of drying devices will become more and more extensive, and the requirements for the quality of dried products will also become higher and higher. Therefore, the vacuum low-temperature continuous drying device can achieve the three control objectives of quality, energy saving, and environmental protection, and can provide a brand-new solution for low-cost, high-quality drying of many materials, and has a strong market competitiveness.
According to different classification methods, drying can be divided into many types. If divided according to the pressure around the material in the process, it can be divided into normal pressure drying and vacuum drying two categories.
Vacuum drying has many advantages. Under the vacuum environment, the boiling point of moisture is reduced, and low-temperature drying can be achieved. This provides favorable conditions for the drying of heat-sensitive materials; the partial pressure of oxygen is reduced, and the phenomenon of oxidation and deterioration of the materials in the drying process can be avoided. The quality of the material to be dried kills some bacteria under hypoxic conditions, which inhibits the growth of some bacteria. At the same time, the vacuum drying process can recover some poisonous, harmful, flammable and explosive gases and prevent environmental pollution; It is said that "green, safe and environmentally friendly" is dry. Heat transfer in the vacuum drying process is divided into three categories, conduction, convection, and radiation. Atmospheric pressure drying mainly uses hot air convection heat transfer, and a large amount of low-level heat energy with the air outside the row drying warehouse. Vacuum drying is the use of closed loop heating in a closed drying chamber, mainly conduction and radiation heat supply to the material, no external heat energy. Practice data shows that vacuum drying equipment to remove 1kg of water and heat energy is only 40%~60% of normal pressure hot air convection drying. In summary, vacuum low temperature drying is high quality, low energy consumption, safe and environmentally friendly drying.
The existing conventional vacuum drying technology equipment is a mature technology drying equipment, which fully shows its technical advantages, but it is intermittent operation, easy mass transfer, and difficult heat transfer. Most of the equipment must use mechanical power to agitate the material in the drying chamber. Therefore, the low output, complicated structure, high manufacturing cost, and high operating cost limit the use of vacuum drying equipment. According to the above-mentioned problems of vacuum drying technology equipment, it is known that there is no vacuum low temperature continuous drying equipment at home and abroad. Combining our experience in vacuum drying technology research and production test research of continuous drying tower equipment for hot air convection, we have boldly proposed vacuum low temperature continuous Dry tower technology equipment research projects, so that the advantages of vacuum drying and tower-type drying equipment, the advantages of non-powered hybrid heating the perfect combination.
Research course:
1. From October 2002 to October 2003, a vacuum drying laboratory for cereals, fruits, and vegetables was studied.
Second, from November 2003 to May 2004, the wrong arrangement of heat transfer tubes was performed, and the gap parameter D>4d test. And in Zhengzhou City, Henan Province, conducted a 20t/d northeastern maize vacuum low temperature continuous drying technology equipment manufacturing and production test study.
3. From June 2004 to May 2005, 60t/d of northeastern maize vacuum low temperature continuous drying equipment was manufactured and produced in Gongzhuling City, Jilin Province.
4. From May 2005 to December 2005, 20t/d boiled and dried peanut vacuum vacuum cryogenic technology equipment was produced and tested in Luojiang, Sichuan Province.
5. From June 2005 to May 2006, a 300t/d drying and vacuum drying facility for northeastern maize was produced in Dehui, Jilin Province.
6. From February 2006 to the present, a series of vacuum drying tests on chemical materials, catalysts, feeds, etc., and production of high-tight rotary valves were adopted to achieve historic breakthroughs.
The above six experimental studies have achieved the desired results. The feasibility of vacuum drying with high quality, low energy consumption, low power consumption and low operating costs is very optimistic. It was finally confirmed that vacuum drying is energy-efficient, environmentally friendly, and the products are highly competitive at home and abroad.
According to the results of various experimental studies conducted in the early stage, in order to achieve complete vacuum drying at low temperatures for particulate materials, the manufacturing costs of such equipment can be approached to the manufacturing costs of atmospheric hot air convection drying equipment, dry heat energy consumption, and electrical energy consumption. The operating and operating costs are significantly lower than the atmospheric hot-air drying costs. There is no vacuum and low-temperature drying equipment of the same type that can achieve the above technical indicators at home and abroad. Under the premise of global energy saving and emission reduction and the market is in urgent need of energy-saving products, we carried out from January 2006 to January 2007. "High heat transfer area ratio thin vacuum drying bin" and its associated "high gas tight rotary valve", "optimized and reasonable vacuum system supporting device" and other technical solutions, experimental research shows: "ZL200620029704.2 high heat transfer “Compared with thin-layer vacuum drying silos†is the core technology of vacuum low-temperature continuous drying technology equipment. After its implementation, it can significantly reduce the cost of vacuum cryogenic continuous drying technology equipment manufacturing, combined with the full implementation of research and test manufacturing results of other supporting equipment. To achieve low-cost manufacturing of the equipment, low-cost operation, according to the characteristics of different industries to develop a reasonable market price, so that manufacturing, sales companies have a huge profit.
Here are the benefits and risks of manufacturing, marketing, and after-sales service for investing in vacuum low-temperature continuous drying equipment as follows:
First, dry technology science is a marginal discipline, interdisciplinary, and it is a complete experimental science and technology. It is unscientific to perform the complete dry process parameter test without the general basic theory calculation, and it is irresponsible to use the equipment user. Although we have done a lot of research and experiments on drying different types of materials in the earlier period, it is still far from enough. We should develop small-scale simulation test equipment for different industries and different users to carry out process test research on different materials. It is also the company’s core technology secret.
Second, drying technology and equipment are non-standardized processing equipment, processing accuracy is not high, the manufacturing process is relatively simple, but in order to improve the technical content of vacuum low temperature continuous drying technology equipment, improve production efficiency, reduce manufacturing costs should be modular design , Modular production, manufacturing plants should be equipped with high degree of automation, high precision, efficient production of manufacturing equipment, can not be like domestic and foreign drying equipment manufacturers use a large number of manual processing, extensive manufacturing, the overall quality of equipment is difficult to guarantee.
Third, the demand for vacuum low temperature continuous drying equipment in many industries. There is no need for drying technical equipment in various industries in GDP. For example: cereals, seeds, fruits and vegetables (dates), drinking supplies (malt, cocoa), feed, chemicals, pharmaceuticals, food, metallurgy, agricultural and sideline products processing, biological products. This puts higher demands on the marketing knowledge of the company's industrial processes and equipment, and therefore must invest in the marketing staff's prior training.
Fourth, factory-manufactured factory drying equipment is still a semi-finished product for the user, and the company must send personnel to transport the factory-manufactured parts to the location of the user's factory for installation and commissioning. After the production is qualified, it will be delivered to the user. The user's operating personnel should also be advanced or Cycle training, users before and after the order but also to the user to make a large number of technical design and coordination of pre-sale services, and thus training high-level after-sales service personnel is to ensure the interests of the production companies the last protection.
The aforementioned four items are risk subjects for investment interests of enterprises, which are based on the status of domestic medium-scale drying equipment manufacturing enterprises. They are estimated to have an annual production value of 400-500 million yuan and an enterprise profit of 5,000-80 million yuan. The above-mentioned enterprises must increase their investment by 1.8 to 2.8 million yuan, and the investment recovery period is 2 to 3 years.
Evasion of investment risks (newly built companies)
First, "the Central Plains have the world." A plant near Zhengzhou, Henan Province, in the hinterland of the Central Plains, should be built to benefit the Chinese market where corporate technology products radiate, and not far from the ports. The factory should be 50~80km away from the central city of Zhengzhou, with convenient transportation location, in order to take advantage of low local land prices, preferential taxation policies, and relatively low labor costs to reduce plant investment costs and production costs. The enterprise management department should be located near the Third Ring Road in the city near the production plant to enhance the corporate image so as to facilitate the exchange of customers and customers. Because the factory's low standard of living and low prices, this will also help increase the benefits of the employees in the manufacturing plant, improve labor productivity, and help protect the plant's technical secrets and trade secrets.
Second, the use of a certain construction scale, production technology and equipment close to the production of vacuum cryogenic drying equipment. Enterprises that use backward technology and have poor operating conditions can use their resources to negotiate mergers, acquisitions, joint ventures, and cooperative production. Can significantly reduce investment risks. If there is an appropriate opportunity to negotiate with the local government of the cooperating enterprise, the use of joint ventures can increase the employment of local personnel, increase local tax revenues, and encourage local governments to give more preferential policies to joint ventures to further reduce the investment risk of enterprises.
Third, according to the authoritative department's research report, the new report and domestic experts' assessment report on foreign countries and related issues, the expert's review and acceptance report on the technology, and the relevant equipment production appraisal report shows: The continuous drying tower equipment ranks among the leading international technologies. The equipment has the following advantages compared to atmospheric hot air convection drying equipment:
1 Low temperature: The principle of using water vaporization evaporation temperature to decrease with the reduction of the ambient pressure, achieve a low temperature of 32~60°C in the vacuum state Drying The heat-sensitive material can be dried to obtain a higher dry product quality.
2 Quality: The application of vacuum technology to the drying of high-moisture grain, overcoming the loss of solute caused by high-temperature drying, avoiding gelatinization and degeneration of starch, maintaining the original physical and chemical properties of food and the proper color, aroma, taste, shape and nutrition Ingredients to solve the problem of cracks and subsequent breakage of grain drying.
3 Energy-saving: Production test data prove that under the same conditions, the energy consumption of the vacuum low-temperature continuous drying device can be reduced by 40% to 60% compared with ordinary hot air drying devices.
4Environmental protection: In vacuum continuous drying at low temperature, the drying medium is closed and circulated in the drying chamber. There is no dust, volatile substances, and odors. The pollution is caused by the discharge of dry exhaust gas to the environment. The environmental protection is high.
5 Safety: It is especially safe that the oxygen in the inflammable and explosive environment is not generated due to the oxygen in the closed vacuum.
6 The low moisture drying of any particle material can be carried out at low cost. Therefore, the equipment is suitable for the general demand of high-quality, high-efficiency, low-cost dry material enterprises, and complies with the national “energy saving and emission reduction†sustainable national economy. The policy requirements of the development strategy will inevitably be favored and supported by government policies.
Fourth, the demand for drying equipment: According to authoritative statistics, the energy consumption of drying equipment accounts for 12% to 18% of the total energy consumption of GDP (different countries and regions have different industrial structures). This shows the importance of drying equipment in industrial and agricultural production. The demand for drying equipment in all industries of GDP is only different. The initial high investment is a basic view of the industry on vacuum low-temperature drying devices, but it is not entirely true. In the field of low-temperature drying, the initial investment in the vacuum cryogenic drying unit is not as high as compared to other conventional low-temperature drying units. With the rapid development and popularization of vacuum technology in recent years, the cost of vacuum equipment and components will become lower and lower, and the initial investment gap between vacuum low-temperature drying devices and conventional drying devices is narrowing. In addition, with the rise of energy prices, operating costs will play an increasingly important role in the user's choice of drying devices, and the energy-saving advantages of vacuum low temperature continuous drying devices will eliminate barriers to high initial investment.
According to reports in the literature, domestic sales of dry equipment market in 2005 can be about 26 billion yuan in statistics, and annual growth in drying equipment is about 15% greener, slightly higher than the growth rate of GDP. Special mention should be made of the dry products purchased by enterprises since 1984. The equipment has reached the second update phase out period, especially the original equipment belongs to the high energy consumption equipment with low thermal efficiency. With the strong demand for high quality, low energy consumption, and low cost drying equipment in various industries, the vacuum low temperature continuous drying equipment is dependent An advantage must have strong market vitality.
V. The above three and four items briefly describe the necessary conditions for avoiding investment risks, market needs and technical advantages of products, but the greatest impact on drying equipment is the ratio of performance to price (generally applicable to any product), as we are studying this topic. Special attention is paid to this most important economic and technical indicator. The factors affecting the price of manufacturing equipment include the cost of purchased parts and the cost of manufacturing, and the reduction of the cost of purchased parts can be achieved through bidding and procurement. The most effective means of reducing manufacturing costs are reasonable detailed structures and relatively simple processing methods. We have also mastered the entire set of technologies for the production of high-performance, low-cost vacuum and low-temperature continuous drying technology equipment in the preliminary tests.
Sixth, drying technology and equipment in the industrial and agricultural production and processing is only a process of product production and processing. During the production and sales of such new high-performance-price ratio drying equipments, the research on the process before and after the drying process should be simultaneously emphasized, and the drying process should be matched with the overall process, or the process before and after the process should be improved and new equipment should be formed. technical equipment. Utilizing our strengths and associated overall process design, we will adopt a united design to create a turnkey project equipment sales capability to create more profits for the company.
The above is our preliminary and superficial view on the benefits, risks, and risk aversion of technical and economic marketing related to the investment in vacuum low temperature continuous drying technology equipment, and is for reference only. In addition, we must specifically point out that the ultimate goal pursued by corporate development is to obtain the maximum legitimate profits, but the decisive factors are not the above, but should be the decision-making, decision-making level, general manager, chairman, or that "prosecution At the management level, things are at the decision-making level (chairman, general manager)." Inappropriate, please correct me.
