How useful is the airflow extruder patent?

The large-scale airflow extruder is the first to be produced and developed in China, and has been continuously improving the research and development, and is currently at the leading level in China, and is also the largest airflow extruder manufacturer in China. Considering that the machine was only an improvement of Japanese technology and did not meet the requirements of the Chinese Patent Law for inventiveness, novelty, and practicability (referred to as the three characteristics), the patent was not applied. At present, there is no inventiveness of the airflow extruder of that factory in China that meets the requirements of the patent law.

However, some companies apply for a patent for an airflow extruder that has no practical significance. They generally apply for a design or utility model patent. The appearance patent is only recognized by the state as having the exclusive right of protection for its appearance, and others may not imitate it, and there is no requirement for the practicability, inventiveness and novelty of the machine.

For utility model patents, the Chinese Patent Office only examines whether the articles in the patent application are written in accordance with the requirements of the Patent Law, and the Patent Office does not care whether the content of the application is inventive, novel and practical, that is to say, whether the product is advanced, real and useful, the Patent Office does not examine. After the patent certificate is granted, if the patent really has the requirements stipulated in the Patent Law, the patentee will sue the infringer, and others will not dare to make a big show of production and sales.

It is precisely because some manufacturers apply for patents just to attract attention, and their products do not have the three characteristics stipulated in the patent law, they spend thousands of yuan to apply for a patent, and go around publicizing and blinding people who are not familiar with the patent law. Such patents do not have the right to sue others except for publicity, advertising, and attracting attention.

Only invention patents are of practical significance, and the other two are patents that are not of much use.

Patents are meant to strengthen a company's image and protect its technology.

Large-scale airflow extruder is a kind of grain puffing equipment, which is composed of several parts, such as puffing tank, heating device, rotating device, safety protection device, vibration damping device, frame, base and so on.

Wuhan Xianglaier Food Machinery Co., Ltd. is the first domestic development, manufacturing, production and sales of large-scale air puffing machine professional manufacturers, the company produces and sells complete sets of rice and wheat equipment, coffee and corn complete sets of equipment, Shaqima complete sets of production equipment, cereal extruder machine, etc., many famous food brands are partners, such as Shanghai Mi Dama, Jiangsu Liangfeng Group, Jiangsu Aqingsao, Anhui Kaili, Anhui Tianhe, Wuhan Zhule, Hubei Geely, Henan Xiangbel, Huaxia Baifen, Avanti and so on, At present, the key process of crispy coffee corn production in the hot market is the airflow puffing of corn, and many roasted food manufacturers such as Heilongjiang, Zunyi, Guizhou, Changsha, Hunan, and Tianjin have purchased large-scale airflow extruders from the company to produce coffee corn.

The company promises free warranty for tanks and motors within one year, and offers preferential access to wearing parts, and technicians can be sent to install, debug and repair. The company provides the national test report of the equipment, which is a necessary document for the application procedures for setting up a factory. Detailed operating instructions and different extrusion pressure data for various cereals are also provided.
