Description
Technical field
The utility model relates to a kind of vacuum belt drier group, is a kind ofly continuously the thick liquid raw material to be coated on the conveyer belt, carries out the equipment of low temperature drying under vacuum state.
Background technology
The drying of present most of plant extracts mainly depends on hot air circulation type oven drying, and part adopts drying under reduced pressure and spray-drying.Mainly there are inhomogeneous, the problems such as the time is long, temperature is high, easy bonding, easily coking, receipts cream difficulty, material loss is big, energy consumption is big of being heated in hot air circulation type oven drying; Though drying under reduced pressure is a a progressive step than hot blast circular form oven drying, but at present the equipment that uses is still simpler, fails effectively to solve that heat transfer efficiency is low, vacuum and temperature lack key issues such as effectively control, and drying time is still longer, efficient is still not high, and quality is still stable inadequately.These two kinds of methods all need at high temperature manually to stir and discharging, severe operational environment, and dry extract need further carry out could packing behind the crushing screening.
Spray-drying is advanced at present technology, is a kind of method that fluidization technique is used for the liquid material drying, has obtained certain applying.Its advantage is directly thin liquid to be become dry powder, and fast drying is worked continuously; Its shortcoming then is the meticulous but not graininess of powder, pulvis densification and poorly water-soluble; Be difficult to handle the bigger medicinal extract of viscosity; Volumetric heat transfer coefficient is little, and dry tenacity is low; The device structure complexity, floor space is big, the cost height.Even more serious is that the temperature of thermal current can influence the color and luster of dry powder up to 300 ℃ during spray-drying, is easy to generate breeze, destroys the active material of some heat sensitivitys simultaneously.In addition, some contain the material of polysaccharide component, if adopt spray-drying, the material that polyoses content is high can be bonded on the wall of spray drying collector, cause and receive the powder difficulty and dry failure.
Summary of the invention
The technical problems to be solved in the utility model provides and a kind ofly works continuously, automaticity height, the excellent vacuum belt drier group of product quality, to overcome the existing existing defective of dry materials method.
For solving the problems of the technologies described above, vacuum belt drier group provided by the utility model is a kind ofly continuously the thick liquid raw material to be coated on the conveyer belt, carries out the equipment of low temperature drying under vacuum state.This unit comprises a vacuum cavity, be provided with the mass transport tape transport in the vacuum cavity, vacuum cavity is connected to and connects adjustable vacuum system, and the front end of unit is provided with feed mechanism and material-feeding mechanism, and the rear end of unit is provided with shut-off mechanism, shovel powder mechanism, disintegrating mechanism and material collector successively.
The utility model vacuum belt drier group, its whole unit can adopt band DCS dcs and touch screen human-computer interface operating system, complex relationship between heating-up temperature, vacuum, chilling temperature, transfer rate and the dry extract quality of unit can be effectively controlled, thereby can make the batch products dry mass more reliable and stable.
Adopt the vacuum belt drier group of said structure, material transmits on health level conveyer belt and is dry, and whole process is finished in the enclosed vacuum cavity, has avoided polluting with contacting of surrounding enviroment; The dry run gentleness, operating temperature is generally 40-60 ℃, material directly enters under the condition of high vacuum degree progressively dry through after a while, and the particle of dry back gained has crystallization effect to a certain degree, from microstructure inside micropore is arranged simultaneously, after directly being crushed to needed particle diameter, particle mobile fine, and have the open structure of microcosmic, instant capacity is fabulous, can keep its rerum natura to greatest extent, obtain high-quality final products.The wide accommodation of reality blanking bar formula dry technology for the overwhelming majority's plant extract, can be suitable for.Especially for the material of viscosity height, easily conglomeration, thermoplasticity, thermal sensitivity, use vacuum belt type drying then can overcome the too thin too close and too high shortcoming of temperature of spray dried powder.In addition, series of parameters such as the belt speed of the conveyer belt of vacuum belt drier group, the thickness of the bed of material, temperature and vacuum all can onlinely be regulated, to adapt to the technological requirement of different products.In this, the belt vacuum drier is far superior to spray dryer.
