Process drying medicinal drug residues

China's pharmaceutical factories produce millions of drug residues every year, but their disposal method is very simple. They either bury it, incinerate it, or simply stack it carelessly. This is, in fact, a waste. Drug residues are not only a misplaced resource, but they can also find new uses. This involves transforming drug residues into organic fertilizers, feeds, and dyes. Of course, many of them claim that drug residues can be obtained from pharmaceutical factories. Dry the drug residues first to facilitate storage and transportation.

Various pharmaceutical companies primarily use the three-axis dryer for drying medicinal residues. In comparison to conventional dehydration drying equipment, the three-axis dryer offers numerous advantages for the drying of medicinal residues, such as:

A large heating area, which is achieved through a special double disc design and a compact structure, nearly doubles the heating area in the same space.

Less coking phenomenon: According to the viscous characteristics of the drug residues, the design adopts the design of two heating spindles rotating at opposite speeds, which can prevent coking on the heating surface of the disc.

Full nutrition: The equipment can be equipped with a complete vacuum system so that the temperature of the material drying process can be controlled at a low temperature and the medicinal value of the material can be preserved to the greatest extent.

Save energy：Under standard conditions, it can dry with 0.6 MPa steam, reducing the cost of the vacuum system.

Run smoothly: The high-quality hard-tooth surface reducer is sleeved on the heating spindle, and the equipment runs more stably and quietly.

Continuous production: The dryer's bottom features a forward and reverse feed shaft that allows for speed and direction adjustments based on the material's drying degree, as well as control over the discharge speed for consistent and steady production.

Stir fry evenly：The powder pusher is installed on the two discs, which is conducive to the stirring of the bottom material, so that the material is heated more evenly.

Discharge advantage：The discharge auger is installed, and the frequency conversion motor is also used to control the start, stop, and speed separately, which reduces the long working time caused by the slow discharge in the later stage and also reduces the material storage inside the cylinder.

Can be equipped with vacuum: A vacuum low-temperature dryer can be selected. During the drying process, the temperature of the material is low, there is no overheating phenomenon, the water is easy to evaporate, and the dried product can form a porous structure with good solubility and rehydration.
