Food is the paramount necessity of the people, and food is an essential resource for them. The storage of food has also become the same. Wet images are not easy to store, so drying equipment has emerged. Drying equipment plays a crucial role in food machinery, whether it is simple food drying treatment or high-tech milk powder production technology, they cannot do without drying equipment. In recent years, the demand for food drying equipment in China has gradually increased, with a market share of over 80% in the domestic market.
Analysis of the Development of Food Drying Equipment in China
Analysis of the Development of Food Drying Equipment in China
Food processing includes many processes such as sorting, crushing, separation, mixing, sterilization, refrigeration, and drying of raw materials, and the drying process is a key link in ensuring food quality. Drying food can prevent the proliferation of microorganisms in the food, facilitate storage, and reduce the volume and weight of the food, thereby reducing transportation costs.
The demand for large-sized equipment and equipment with functional combinations (such as granulation drying, drying filtration) in vacuum freeze-drying equipment is constantly increasing, and highly automated drying equipment is also very popular in some application fields. In addition, drying equipment with good appearance quality and corrosive material drying equipment with strong corrosion resistance and long service life have also received special attention from downstream enterprises.
According to China Food Machinery Equipment Network, currently, most of the conventional drying equipment and major market drying equipment in the domestic market are manufactured in China. However, the price of drying equipment in our country is less than half of that of similar foreign products, and the innovation ability of drying equipment production enterprises is generally low.
Technological innovation is a major trend in social development, and only by standing at the forefront of technological updates can we dominate the market. Therefore, while enhancing development confidence, drying equipment should also maintain a clear mind, recognize the shortcomings in the industry, and achieve industry development and upgrading through technological transformation.
Drying equipment with good market response
Boiling granulator dryer, commonly known as one-step granulator in China, was designed based on the introduction of similar foreign products in the 1980s, after digestion, absorption, and improvement. Due to its simple operation, superior performance, and excellent manufacturing, especially its ability to meet GMP requirements in the pharmaceutical and food industries, this device is highly welcomed by users in the pharmaceutical and food industries. This equipment is particularly suitable for drying and granulating traditional Chinese and Western medicine, as well as food products. The resulting particles have strong disintegration, good fluidity, and good instant solubility. They can be directly used for tablet pressing, capsule filling, as granules and solid beverages.
The centrifugal spray dryer has achieved ideal application results in the fields of dyes, dairy products, etc. Over the years, this equipment has been widely used, with significant progress in technology and manufacturing quality. In recent years, large-scale centrifugal spray dryer has also attracted attention in the application of flue gas desulfurization, and its development prospect cannot be ignored.
There is a high demand for grain drying and storage equipment. At present, the drying and storage of grain have received high attention from various sectors, coupled with environmental requirements, China has begun to transform the previous situation where grain drying mainly relied on natural air drying, and grain drying and storage equipment have begun to be widely promoted.
Large scale steam, vacuum freeze-drying machine steam, and vacuum freeze-drying machine are key equipment to ensure the quality of biopharmaceuticals. With the improvement of people's living standards, the demand for vacuum frozen foods, vegetables, health products, and nutritional supplements with good rehydration, color, and nutrient retention is constantly increasing. Therefore, the demand for large-scale vacuum freeze-drying equipment to meet the needs of these products will also increase.
In fact, currently, regardless of which drying equipment, its development still needs to pay attention to energy conservation and comprehensive energy utilization, such as using various combined heating methods, transplanting heat pump and heat pipe technology, developing solar drying machines, etc; We also need to develop automatic control technology for dryers to ensure the implementation of optimal operating conditions; In addition, with the increasing emphasis on environmental protection by humans, measures to improve dryers to reduce the leakage of dust and exhaust gases will also be a direction that requires in-depth research.
At present, compared with developed countries, there is still a certain gap in the quality and technical level of domestic products. Therefore, Chinese drying equipment manufacturing enterprises still need to learn from technology, combine practical experience, develop new technologies, and achieve high economic efficiency and integration of drying equipment in China.
The joint development of drying equipment into a new direction for the industry
Drying is a very important unit operation in the field of food processing. In the food processing industry, the demand for drying equipment in China will still be huge in the coming years, and the requirements will continue to increase. How drying equipment can meet the development of the industry has become a focus of attention for relevant enterprises.
We know that the drying of materials is often due to one or more of the following reasons: good fluidity of materials, easy loading and unloading, easy preservation and storage, reduced transportation costs, achieving desired product quality, etc. In the production process, due to the need for further improvement in equipment quality, supporting components, and basic research, conventional drying is still the main form of drying.
Due to the advantages and applicability of each type of drying, combined drying will be the trend of future development. The development of dryer equipment also needs to pay attention to energy conservation and comprehensive energy utilization, such as using various combined heating methods, transplanting heat pump and heat pipe technology, and developing solar powered dryers; We also need to develop automatic control technology for rotary drum dryers to ensure the implementation of optimal operating conditions; In addition, with the increasing emphasis on environmental protection by humans, improving measures for rotary dryers to reduce the leakage of dust and exhaust gases will also be a direction that requires in-depth research.
