Introduction: In recent years, my country's agricultural screw press (snail diameter ≤200mm) industry has become increasingly competitive. A few production companies are based on their own interests and freely speculate on the idea that the higher the number of presses, the better. There have been five levels in the market. For screw presses with six-stage or even seven-stage and eight-stage presses, is it true that the higher the number of compression stages, the better?
 
In response to the issue of the number of screw presses, it was sponsored by the China Agricultural Machinery Industry Association on March 18, 2015, the Chinese Academy of Agricultural Mechanization Science, the National Agricultural Machinery Standardization Technical Committee, the Agricultural Machinery Testing and Appraisal Station of the Ministry of Agriculture, and the National Grain and Oil Processing Machinery Quality Supervision and Inspection Center, drafter of "Agricultural Screw Press Industry Standard", Sichuan Qingjiang Machinery Co., Ltd., Beijing Yijiayi Machinery Technology Research Institute, Hubei Gongan County Gongle Grain and Oil Machinery Co., Ltd., Guanghan City Shuhan Grain and Oil Machinery Co., Ltd. and Henan Xinxiang Machinery Co., Ltd. jointly participated in the "2015 Screw Press Industry Experts Seminar" held in Beijing China Academy of Agricultural Mechanization Sciences. They discussed the issues related to the number of pressing stages of agricultural oil presses.

Participants at the seminar jointly analyzed the current development status of the agricultural screw press industry, discussed the industry standard of "Agricultural Screw Press", studied how to scientifically standardize the press series of agricultural screw presses, and reviewed the industry technology Development history, watching videos related to end users, most of the participants believed that the maximum number of pressing stages of small and medium-sized oil presses with a screw diameter of 200mm or less is designed to be up to 4. It is not recommended to produce or promote the production or promotion of five, six or six Medium and small screw oil press above grade. On the premise of ensuring product performance, shorten the length of the press chamber as much as possible to reduce production and manufacturing costs and reduce user costs. However, the large-scale screw press with a diameter of more than 200mm can be designed to five, six or even seven and eight levels, and its scientific and practicality will be a future research direction. Individual experts also said that companies should not be prevented from developing and producing five- and six-level small and medium-sized oil presses, allowing companies to develop and innovate, and let the market verify whether they are practical. However, the participating experts, scholars, and business representatives unanimously opposed using the number of oil presses to falsely and exaggerate the functions of the product.

This meeting played a key role in guiding the normal market order of oil presses, transmitting authoritative product information, and calling for orderly competition among enterprises. The participating oil press manufacturers stated that they would implement the "Agricultural Screw Press Industry Standards", standardize the order of industry competition, do a good job in product publicity work from reality, and help users to scientifically select screw presses with reasonable compression levels to promote The healthy development of the screw press industry, strive to scientifically standardize the number of pressing stages of the agricultural screw press, resist false propaganda, and establish a new image of the screw press.

For companies that use the oil press to make false propaganda, it has caused great confusion and considerable economic losses for users to choose. This kind of disregarded propaganda will inevitably lead to more users suffering losses, to a certain extent May trigger a crisis of trust in the entire oil press industry. This meeting also gave warnings to this phenomenon, advocating everyone to jointly maintain the credibility of the industry.

This conference has built a communication bridge between industry management departments and enterprises, and is an important platform for communication and cooperation in the field of small screw presses (screw diameter ≤200mm) and even screw press related fields in China. This seminar It will bring new ideas to the development of the oil press industry, and promote more companies to provide consumers with a more perfect series of screw press products, which is of far-reaching significance to the development of the oil press industry.

CCTV7, China Agricultural Mechanization Information Network, China Agricultural Mechanization Herald, "Grain and Oil Processing" magazine and many other related media have carried out detailed reports on this meeting. You can learn about other contents of the meeting through follow-up reports.

Respect science, strictly supervise, based on science and technology, healthy development

As the organizer of this conference, Dang Dongmin, deputy director of the Industry Work Department of China Agricultural Machinery Industry Association, delivered a welcome speech at the beginning of the seminar. Welcome everyone to discuss related issues, so as to promote the healthy development of the industry.

Afterwards, participating experts, scholars and business representatives discussed the current development status of the agricultural screw press industry.

Then, the drafter of the "Agricultural Screw Press Industry Standard", researcher Li Zhiqing from the Chinese Academy of Agricultural Machinery, the drafter of the "Agricultural Screw Press Industry Standard", Du Jiankang, Chairman of Sichuan Qingjiang Machinery Co., Ltd., and a well-known old expert in the agricultural screw press industry --Researcher Lv Longqi of Yantai Agricultural Machinery Research Institute (enjoy national subsidy), and Huang Yunlian, general manager of Beijing Yijiayi Machinery Technology Research Institute, respectively made keynote speeches at the seminar.

Researcher Li Zhiqing of the Chinese Academy of Agricultural Machinery said in his speech: Recently, it was discovered that in the sales market of screw presses in China, five-stage, six-stage and seven-stage presses appeared on the basis of the original two-stage, three-stage and four-stage presses. The screw oil press made it difficult for users to choose an oil press. The main reason is that a small number of companies have not been fully verified by scientific experiments and the market, and they have not fully analyzed the effect of the compression series on the oil quality and dry cake residual oil. The oil output efficiency and the power consumption per ton of material are closely related. The oil output and pressing performance of the high-pressure press series are arbitrarily exaggerated, and the screw presses of the second, third, and fourth-stage presses are eliminated without scientific basis. This kind of disrespect for science and disregard for the interests of customers has attracted the attention of the industry and related departments. In order not to infringe the vital interests of the majority of users, we have the responsibility and obligation to conduct scientific analysis with a scientific and responsible attitude, and provide the majority of users in our country with technologically advanced and economical screw press products.

Researcher Lu Longqi from Yantai Agricultural Machinery Research Institute reviewed the development process of screw presses, from the introduction of screw presses in the 1960s to the map of screw presses in the 1980s. The industry standard was formulated for the first time. Through many tests, it has been fully verified that the second and third-stage screw presses can meet the pressing requirements of various oils. The fourth-stage press will also be the highest number of agricultural screw presses, three and four. The operating performance of the high-grade screw press fully meets the requirements of the industry standard. Under the premise of perfect operation technology, it can not only ensure the oil removal efficiency, but also reduce the residual oil rate of the dry cake to 5%. Regarding the emergence of agricultural screw presses with five-stage, six-stage, or even seven- and eight-stage presses, and the denial of the second, third, and fourth-stage screw presses in the promotion of certain products, I do not understand them very much. Unrealistic and even absurd.

The drafter of "Agricultural Screw Press Industry Standard" and chairman of Sichuan Qingjiang Machinery Co., Ltd. Du Jiankang believed that the emergence of agricultural screw presses with five, six, or even seven and eight levels is simply a heavenly night. Tan, incredible.

 Huang Yunlian, general manager of Beijing Yijiayi Machinery Technology Research Institute, hopes that all oil press sales companies should proceed from the actual situation, seek truth from facts, do a good job in the promotion of enterprises and products, and oppose the use of oil presses to amplify and degrade the actual performance of products; Adequate attention should be paid to the reasonable demands of users. It is recommended that oil press manufacturers develop more crude oil processing equipment that is highly automated and easy to operate to improve the competitiveness of small and medium-sized oil mills.

Introspection and self-discipline, perfect norms, improve science, evolve industry

When watching related videos, everyone found that the user could not use the oil presses of a company’s 5th and 6th squeezers. Facing the legitimate demands of customers, the sales company used the overlord clause signed by the purchase to shirk responsibility. No way to complain, no tears.

In response to this phenomenon, the representatives of the experts at the seminar agreed that oil press manufacturers should jointly resist this illegal behavior that disregards the interests of users to maliciously speculate on the squeezing series, falsely promote product performance, and harm the vital interests of users. The users of screw oil presses are generally farmers, with immature consumption concepts and lack of self-protection awareness. They have little knowledge of the "Consumer Rights Protection Law", "Product Quality Law" and other national quality laws and regulations. Organizations don’t know much about it. They tend to believe in the exaggerated promises of sales companies and the pseudo-scientific concept that the higher the number of oil presses, the better. They don’t understand the three major elements of oil presses—oil output efficiency, electricity consumption per ton, and dryness. The interrelationship of the cake oil is also due to the poor awareness of rights protection and the high cost of rights protection. After the product has quality problems, most users choose to consider themselves unlucky and do not know or are unwilling to protect their legitimate interests through rights protection organizations.

Everyone requested that, while producing in strict accordance with industry standards, all screw press manufacturers should also strictly follow the regulations of the Ministry of Agriculture for the promotion and appraisal of agricultural machinery, improve the quality management system, improve the inspection capabilities, improve the technical level, and operate properly. Thinking, continuously improve product quality; all production or assembly sales companies mark the name of the production company and sales company in a prominent position of the oil press, so that customers have more right to know.

Finally, researcher Li Zhiqing of the Chinese Academy of Agricultural Machinery, Chairman Du Jiankang of Sichuan Qingjiang Machinery Co., Ltd., and General Manager Huang Yunlian of Beijing Yijiayi Machinery Technology Research Institute proposed to the oil press industry at the seminar: Oil press companies should actively respond to the association’s Requirement, earnestly fulfill social responsibilities, resolutely achieve perfect specifications, and strive to be an industry model; call on the Oil Press Association to give full play to the organization, coordination, service and supervision functions of the association, safeguard the common economic interests of member companies, provide market information, and regulate the market Conduct together to resist unfair competition inside and outside the industry.
