New Trends in the Integration of Drying Equipment into the Chemical Industry Process

Food is of paramount importance to the people, and food is an essential resource for them. Food storage has also become an essential resource. 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 processing or high-tech milk powder production processes, they cannot do without drying equipment. In recent years, the demand for food drying equipment in China has gradually increased, and its market share in the domestic market has reached over 80%.

A Brief 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 larger specification equipment and equipment with functional combinations (such as granulation drying, drying filtration) in vacuum freeze-drying equipment is increasing, and highly automated drying equipment is also very popular in some application fields. In addition, drying equipment with good appearance quality and strong corrosion resistance and long service life for corrosive materials have also received special attention from downstream enterprises.

According to China Food Machinery Equipment Network, currently, the conventional drying equipment in the domestic market, as well as the main market drying equipment, are mostly manufactured in China. But the price of drying equipment in our country is less than half of the same products abroad, and the innovation ability of drying equipment manufacturers 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 granulation dryer, commonly known as one-step granulator in China, is designed based on the introduction of similar foreign products in the 1980s, after digestion, absorption, and improvement. Due to its easy operation, superior performance, and excellent manufacturing, especially meeting the GMP requirements of the pharmaceutical and food industries, this device is highly welcomed by users in the pharmaceutical and food fields. This device is particularly suitable for drying and granulation of traditional Chinese and Western medicine as well as food products. The resulting particles have strong disintegration, good fluidity, and good solubility, and can be directly used for tablet pressing, capsule filling, granule preparation, and solid beverages.

The centrifugal spray dryer has achieved ideal application results in the fields of dyes, dairy products, etc. Over the years, this device has been widely used, and its technological level and manufacturing quality have made significant progress. 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 storage equipment in grain drying warehouses. At present, the drying and storage of grain have received high attention from various countries, and with the requirements of environmental protection, China has begun to change the previous situation where grain drying mainly relied on natural drying. Grain drying and storage equipment has begun to be widely promoted.

Large steam and vacuum freeze dryers are key equipment for ensuring the quality of biopharmaceuticals. With the improvement of people's living standards, the demand for vacuum frozen foods, vegetables, health supplements, and nutritional supplements with good rehydration, color, and nutrient retention is constantly increasing. Therefore, the demand for large-scale vacuum freeze-drying equipment that meets the needs of these products will also increase accordingly.

In fact, currently, regardless of the type of drying equipment, its development still needs to pay attention to energy conservation and comprehensive energy utilization, such as adopting various combined heating methods, transplanting heat pumps and heat pipe technology, developing solar drying machines, etc; We also need to develop automatic control technology for drying machines to ensure the realization of optimal operating conditions; In addition, with the increasing emphasis on environmental protection by humans, improving measures for drying machines 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 technological 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.

New directions for the development of the drying equipment joint chemical 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 to meet the development of the industry with drying equipment has become a focus of attention for related enterprises.

We know that the drying of materials is often due to one or more of the following reasons: making the material have good fluidity, easy loading and unloading, easy storage and preservation, reducing transportation costs, and achieving the desired product quality. 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 adopting various combined heating methods, transplanting heat pumps and heat pipe technologies, and developing solar dryers; We also need to develop automatic control technology for rotary drum dryers to ensure the realization 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.
