First, the development process of food machinery is divided into several stages

The development process of China's food industry and food machinery can be roughly divided into three stages.

1. The first stage

Before the 50s of the 20th century, the production and processing of food was mainly manual operation, which basically belonged to the traditional workshop production method. Only in some large coastal cities there are a small number of food processing plants with industrial production methods, and the equipment used is almost entirely foreign equipment. Grain processing plants are doing slightly better than food processing plants. The grain processing plants of industrial production at this stage are mainly based on the industrial production and processing of flour. But equally, the equipment used in flour mills is almost entirely foreign. It can be said that before the 50s, there was hardly a decent factory specializing in the production of food machinery in the country.

2. The second stage

In the 50s and 70s, the food processing industry and food machinery industry were greatly developed, and a large number of food processing plants were built in the second phase throughout the country, especially the production and processing plants of flour, rice and edible oil. Initial mechanized industrial production has largely been implemented in most major grain processing plants. However, the food processing plants in the same period were still in the semi-mechanical and semi-manual production mode, and mechanical processing was only used in some key major processes, while other production processes still followed the traditional manual operation mode. In line with the development of the food industry at this stage, the food machinery industry has also developed rapidly, and a new year of development has been built throughout the country, making domestic batch manufacturing plants specializing in the production of grain and food machinery. After nearly 30 years of development, the domestic food machinery industry can basically meet the needs of China's food industry development, and has made a significant contribution to the realization of food industrial production at this stage, and the food machinery industry has initially formed an independent machinery industry.

3. The third stage

After the reform years after the 80s, the food industry has developed rapidly. This is thanks to the third stage, the opening policy, with the introduction of foreign capital, there are many food processing enterprises in the form of wholly foreign-owned and joint ventures. While these enterprises introduce advanced food production technology into China, they also introduce a large number of advanced food machinery into China. Affected by this, coupled with the improvement of social requirements for the quality, variety and quantity of food processing, it has greatly promoted the development process and speed of China's food industry and food machinery manufacturing industry. At this stage, through the digestion and absorption of foreign advanced food machinery technology, the development level of China's food machinery industry has been greatly improved. In the mid-80s, China's grain processing industry and food processing industry implemented the first round of large-scale technological transformation projects. After this round of technological transformation projects, the food industry has fully realized mechanization and automation. After entering the 90s, a new round of technological transformation projects was carried out. In this round of technological transformation, many grain processing plants and food processing plants have upgraded their equipment, or directly introduced a full set of foreign advanced equipment, or adopted new machinery and equipment digested and absorbed by domestic manufacturers. It can be said that these two rounds of technological transformation projects have greatly promoted the development of the food machinery industry, and the food machinery industry has completely formed an independent machinery industry.

Second, what is the future development trend of the food machinery industry

1. Food machinery products are more diversified, serialized and complete

With the increasing improvement of people's living standards and the further development of the food industry, higher requirements have been put forward for food machinery. In addition to the traditional food industry, the vigorous development of convenience foods (such as instant rice, instant noodles, convenient dumplings, etc.), functional foods (such as infant food, food for the elderly, military food in the field, food suitable for diabetics, etc.), health food, etc., will surely make the variety of food machinery more abundant, while food machinery and equipment serialization, higher degree of standardization, stronger completeness, less stand-alone operation, such as pectin processing equipment for recycling pectin from the peel, vegetable deep processing technology, Juice aroma recovery equipment will be widely used in China.

2. Production automation and intelligent management

In the production of food machinery enterprises, a fully automatic manufacturing system will be widely adopted, the production process is programmed, and the products in the production process are inspected online, which greatly reduces the scrap rate. Implement top-down scheduling, data collection, processing, output and other computer management to improve product quality and ensure the stability of product performance.

3. High-tech is widely used

The future food machinery is a collection of light, electricity, sound, magnetic, chemical, bio-equal high-tech, high-intelligence products, its technical advantages are mainly reflected in the high degree of product automation, high production efficiency, high utilization of food resources, high energy saving of products and high-tech practicality. Such as: ultrafiltration or reverse osmosis membrane separation technology, supercritical extraction technology (for the production of natural food coloring, flavor, flavor, etc.), ultrafine crushing technology, food cold sterilization technology (such as short-time pulse high voltage sterilization, electromagnetic field sterilization), microencapsulation technology.

4. Combined application of biotechnology and food machinery

The combination of biotechnology and food machinery broadens the application range of food machinery. If the crude pectinase preparation containing cellulase and hemicellulase is used to act on the fruit skin layer, so that the cortical cells are separated, the structure is destroyed and shed, this enzyme engineering technology is not only simple to equip compared with the traditional mechanical peeling machine, but also has a good peeling effect. Another example: a biosensor is an analytical tool or system composed of immobilized and chemical molecular recognition functions of biological materials (enzymes, cells, antibodies, etc.), transducer devices and signal amplification devices, which will replace the traditional complex detection instruments (equipment), which can quickly detect food freshness, taste, and doneness, and can be used for food analysis (such as detection of protein, amino acid, sugar content, etc.), and for food hygiene testing (such as the determination of bacteria, pathogenic bacteria, toxins, residual pesticides, food additives).
