Brief introduction and performance characteristics of rotary drum drying equipment:

Brief introduction and performance characteristics of rotary drum drying equipment:

The wet material is fed from the higher end of the drum, the hot air enters from the other end, the drum rolls slowly, and the gas is solid in the drum

The inner countercurrent touch, following the rotation of the drum, the material flows to the lower end under the effect of gravity. Generally, the inner wall of the drum is equipped with

Several copy boards, the effect is to pick up the material and then sprinkle it down to increase the drying surface area, improve the drying rate, and at the same time.

Promote the material to move forward. When the drum rotates once, the material is picked up and sprinkled down once, and the material travels at an interval equal to its

The height of the drop is multiplied by the inclination of the drum. There are various types of copying boards, and different copying boards can be used in the same reversing cylinder. 

In order to reduce the flying of dust, the speed of the gas in the dryer should not be too high. For materials with a particle size of about 1mm, the gas

The body speed is 0.3~1.0m/s; for materials with a particle size of about 5mm, the gas speed is below 3m/s, sometimes in order to avoid powder in the drum

Dust outflow, vacuum operation can be used. The volumetric heat transfer coefficient of the tumble dryer is low, about 0.2~0.5W/(m3·℃)

.  For materials that are capable of high temperature and are not afraid of pollution, flue gas can also be used as a drying medium. about not being contaminated or

For materials that are likely to cause a lot of dust, directly heated rotary drum drying equipment can be used.

Rotary vacuum dryer oven drying method, spray drying method

Drying equipment is widely used in pharmaceutical, chemical and other industries. At the same time, with the continuous improvement of industrial production technology level and consumer requirements, higher technical requirements are also put forward for drying equipment.

Compared with the currently commonly used oven drying method, spray drying method, etc., the vacuum continuous drying method has many unique advantages, and the product quality is much higher than that of other drying methods. Vacuum continuous drying equipment and technology have the advantages of low temperature drying, less damage to active ingredients, loose and easy to dissolve and absorb, drying and sterilization at the same time, so as to ensure high active ingredients, high sterility index, and good oral absorption.

Domestic enterprises have accelerated the research on vacuum drying technology, and some enterprises have also made breakthrough progress, reducing energy consumption and pollution to a certain extent, bringing more benefits and value to the society.
