Vacuum kneading dryer is a kind of vacuum dryer. Of course, vacuum drying equipment is currently produced in various forms: double cone rotary vacuum dryer, vertical agitating vacuum dryer, vacuum disc dryer and the like. The vacuum dryer is unique in that it is equipped with a æ…æ‹Œ-type stirring device, which is continuously rotated and tumbling in the cylinder to make the material more evenly heated, so it is widely used in slurry, paste and paste materials. Wait for drying. However, the same type of kneading device makes the vacuum kneading machine have certain limitations and can only be used for drying materials below 100 mesh.
When the wet material enters the vacuum kneading dryer, the caries are continuously rotated forward and backward to achieve agitation, so that the surface of the material contacted by the inner wall is continuously updated. After the surface of the food material is heated by steam, the water will be vaporized and discharged through a dry dust collector, a wet dust collector, a condenser, etc., and the inside of the food material will be distributed along the food layer to the surface layer due to the difference in moisture content with the skin. The process of gasification is discharged to achieve drying of the ingredients. In order to solve the phenomenon that some materials agglomerate during drying, the material may be unevenly dried. The vacuum kneading dryer is equipped with a pulverizing rod, and the material agglomeration phenomenon is reduced by the action of the pulverizing rod and the kneading stirring device.
The drying process is under vacuum and the water does not need to be above 100 °C to complete the gasification process. This makes the drying temperature of the material greatly reduced, which is beneficial to the retention of the heat-sensitive component in the food, and can retain more nutrients in comparison. In addition, this high vacuum means good sealing, and it has great advantages for some oxidizing materials and gases that will cause serious damage to the environment after gasification. When garlic is made into dehydrated garlic slices, the water produced contains garlic polysaccharides, alliin and other substances, which are extremely damaging to the environment. The vacuum kneading dryer reduces the possibility of exhaust gas spillage and collects the wastewater for disposal.
In order to further improve the drying efficiency, the vacuum kneading dryer not only internally stirs the heating device, but also the interlayer can simultaneously generate heat, so that the heat transfer area is greatly enhanced and the thermal efficiency is improved. Generally, vacuum kneading dryers use steam to pass through the interlayer to achieve heat generation in the interlayer. This treatment method makes the steam need a small heating range, and can achieve energy saving to a certain extent while achieving rapid heating.
In addition, the vacuum squeezing dryer has good adaptability, and can increase the vibrating device according to the demand, which is convenient for drying the viscous material; and can also be configured according to different materials to enhance the convenience of drying and discharging; The company installed an automatic control system for the vacuum sputum dryer, which can detect the agglomeration by itself and start the smashing rod and other devices as needed to further realize energy saving of the equipment.
As a member of the dryer industry, vacuum kneading dryers still face the problem of insufficient innovation and innovation, and it is hoped that relevant manufacturers can see the demand for intelligent equipment in current food production enterprises and accelerate vacuum. The research and development of the dryer has promoted the further expansion of the market.
Enterprises need to strengthen the development of vacuum dryers
In the pharmaceutical and food industry, drying equipment is widely used and plays an important role. The use of grain dryers like grain harvesting will greatly enhance the production efficiency of grain; all kinds of brewed beverages need spray drying equipment to make granules; the current drying of fruits and vegetables that cater to people's health and convenience needs to be vacuum freeze-drying equipment. The ingredients are more nutritious... So today we are talking about vacuum-type dryers that are less recognizable.
