Horizontal spray dryer
    • Horizontal spray dryer
  • Product Details

Compared with the large vertical drying equipment, the horizontal spray drying equipment manufactured by our company has the advantages of compact structure, small floor area, convenient operation and maintenance. It has obvious advantages in energy consumption, product quality, automation and so on, and is a replacement product for vertical spray drying equipment.


Working principle


Horizontal spray dryer is simple in operation, high in automation and low in failure rate. The equipment is easy to clean and has no dead angle. Cleaning, maintenance and maintenance in the horizontal drying box need a high-pressure cleaner. Workers stand up and work easily without safety hazards. The vertical drying inner cleaning is tens of meters high from the ground, and can not be cleaned, leaving dead corners. Workers operate at high altitude in maintenance. Safety and ease are obvious.


Product characteristics


The special exhaust heat recovery waste heat system of horizontal spray dryer can significantly reduce energy consumption and improve the heat utilization ratio of the dryer, saving energy consumption by 30% compared to the vertical dryer. For vertical spray dryer, no one has passed the recovery system, powder air duct, cyclone separator, bag filter and so on. There are many heat dissipating instant noodles. Some equipment has no insulation layer, which greatly increases the heat loss. According to our company's many years of practical experience, for vertical dryer without heat recovery system and large heat dissipation, its water evaporation unit heat consumption is about 1300 kcal/kg of water, then for 1000 kg/h water evaporation dryer, the vertical dryer will pay about 43,000 kcal per hour more heat consumption (86 kg more than 5000 kcal per hour). Calcium standard coal or 50 cubic meters of natural gas, gas standard value is 8500 kcal/cubic meters.


Modern processing industry constantly pursues the improvement of efficiency, in order to reduce drying time, drying equipment is needed. In the current drying equipment, horizontal spray dryer is a popular product, which is widely used in the drying of solution, suspension and slurry materials.


If we do statistics on drying equipment in different industries, we will find that the horizontal spray dryer has a higher market share, because it can adjust operating conditions in a large range, so that the processed products have better quality indicators, such as particle size distribution, bioactivity, solubility and so on, and the drying time needed is very short. The product is of good quality and can even improve the dissolution rate of some preparations. It can also be used for drying thermally sensitive drugs.



For its advantages, we can analyze its working principle. The horizontal spray dryer equipment atomized the material by compressing air or compressing water vapour, and then under mechanical action, the materials waiting for drying were dispersed into fine fog like particles, which fully contacted with hot air, and could quickly go out of most of the moisture, while drying solid materials in the material into powder.


Therefore, we can understand why the horizontal spray dryer is drying so fast. Not only that, it also has excellent homogeneity, fluidity and first-class solubility, so that the product has good quality and high purity. The whole production process is simple, easy to operate, and after drying, the grinding and screening process is omitted, and the production efficiency is improved.


In order to further enhance its performance and efficiency, there have been some spray drying machines equipped with granulation in the market, which will improve the quality of its work. However, it should be noted that this may also increase the thermal denaturation of products, and may cause partial loss of aromatic substances.


Under such a development trend, we can think that in the future market, if we want to achieve a good position and development, then for horizontal spray drying tower, we must achieve energy saving and environmental protection. In recent years, domestic research in this area has made great breakthroughs, and at the expense of a large amount of money to introduce some more advanced foreign technology, so domestic drying equipment has also made great progress in performance, welcomed by the food and pharmaceutical industries.


However, as a whole, our domestic research on horizontal spray drying tower should continue to make efforts to ensure its development status and level in the world. Its main characteristics can be summarized as rapid drying speed. Some equipment will be equipped with two additional devices, called granulation equipment, which can not only enhance the solubility of products, but also improve their packaging performance, ensure the quality of processing, and wide applicability.


We say that the future development will continue to tend to energy saving and environmental protection, so we can consider from the comprehensive utilization of energy and energy conservation, through the use of different heating methods to improve drying efficiency. At the same time, we must pay attention to the development of automatic control technology and realize its application in horizontal spray drying tower, so as to achieve the best drying effect. In addition, we should also improve the leakage situation and reduce the amount of dust and exhaust emissions.


Due to the differences in function and application of different equipment, there are still some problems in the function utilization of equipment. The conventional spray dryer is still the main problem, but in the future, the joint spray dryer will be a new development trend.


The horizontal spray drying tower has high drying speed and atomized material.
