Development space of food drying machinery

Deep processing of agricultural and sideline products is a variety of engineering technologies for processing various agricultural products and materials. It is realized by using physical, chemical, biological and other technologies and mechanical engineering methods. The processed products are widely used in people's diet, animal feed, clothing, shoes and hats, medicine and health care, building materials and various production and daily necessities, of which about 40% are used for processing food and feed. In 2000, the output value of the food industry accounted for 39.47% of the total output value of the agricultural product processing industry. The main products were sugar, tobacco, wine and feed. Vegetable oil processing, slaughtering and meat and egg processing also accounted for a considerable proportion. In China's "Tenth Five-Year Plan", the proportion of food industry output value to agricultural output value will increase from 0.3 to 0.4 to 0.5. By 2005, the proportion of meat processing will increase from 4% to 10%, that is, the volume of meat processing will reach 6 million tons; The proportion of grain processing increased from 8% to 15%, reaching 82.5 million tons, and the output of sugar, dairy products, liquid milk, various feeds, edible vegetable oil and canned food reached 10 million tons, 0.8 million tons, 2 million tons, 27 million tons, 30 million tons and 3.8 million tons respectively. By 2005, the incremental demand for food and packaging machinery from the above industries will reach 15 to 20 billion yuan.

In addition, China's annual vegetable output is 460 million tons, fruit 62 million tons, aquatic products 42.79 million tons, poultry eggs 21 million tons, and fresh potatoes 150 million tons. At present, the processing and storage capacity is very small. For example, among 460 million tons of vegetables, the amount of processing and storage accounts for only 5% - 10%, mainly for export, earning more than 200 million dollars in foreign exchange each year, while the amount of processing and storage in developed countries accounts for about 20% - 60%; If domestic demand starts and exports continue to increase, there is a great possibility of doubling.

The total amount of aquatic products in China has reached 42.79 million tons, and the processing volume has accounted for 29.85%. More than ten categories of processing industries have been formed, but the processing volume of inland aquatic products is still very small. To strengthen the comprehensive utilization of resources, processing equipment must be improved.

The main problem of grain processing is the low utilization rate of grain resources, the average utilization rate is less than 70%. Compared with foreign countries, the flour yield of the same variety of flour is 2% - 4% lower, and the rice yield of the same variety of rice is 4% - 5% lower. The equipment and technology of grain processing should be greatly improved to meet the requirements of the new era. The comprehensive utilization of by-products of grain processing is an important way to improve the utilization rate of grain resources, which is a huge renewable resource in China. The full utilization of grain resources by developed countries (such as the United States and Japan) makes the value of comprehensive utilization of by-products exceed the value of rice, wheat and corn by 3-5 times. For example, the comprehensive utilization of rice bran can produce dozens of edible and industrial products, increasing the added value of rice bran by 60 times, the comprehensive utilization of wheat bran can increase the value of wheat bran by 5 times, the comprehensive utilization of rice husk can increase the value of rice husk by 3 times, and the comprehensive utilization of broken rice can increase the added value by 10 times. In short, China's comprehensive utilization level of grain by-products is still very low. The jujube drying equipment produced by Henan Zhongsen Intelligent Equipment Manufacturing Co., Ltd. is not only reliable in quality, but also convenient in use, simple in operation, uniform in drying, and adjustable in temperature. It not only provides the way for people to become rich, but also avoids the great worry of jujube rot and black spot in (10-30) minutes when the jujube farmers bake fresh jujube.
