1, a comprehensive application of several heat transfer forms. The advantages of various heat transfer modes are made available at different stages of drying, so that the drying equipment can be used more reasonably.
2. The equipment will grow to large scale. Any production has the best economic scale, and the amplification technology of drying equipment can guarantee large-scale production. Therefore, the large-scale research of equipment is one of the development directions in the future.
3, drying equipment will achieve specialization. Drying equipment is a non-standard equipment, the reason why non-standard equipment is mainly deal with the material properties and product requirements vary greatly, so there is a true right design of drying equipment can play its role, from technology to the economy have a certain significance.
4, will tend to multi-stage and combined drying system development. Different types of drying equipment can be applied to different materials or can be applied to different drying stages of the materials. Combined drying can maximize the optimization of the drying process and make the drying system more reasonable.
5, the device will achieve multi-function. At present, the drying equipment is not only limited to the drying operation. Sometimes, the smashing, grading, and even heating reactions are collected in a single machine, which greatly shortens the production process and makes the equipment more versatile.
Classification of tablet press: Models can be divided into single punch tablet press, rotary tablet press, sub-high speed rotary tablet press, automatic high speed tablet press and rotary core tablet press.
The sheet shape pressed by the tablet press is initially flat circular, and later developed into shallow circular arc and deep circular arc on both sides, which is for the need of coating. With the development of special-shaped tablet press, oval, triangle, oblong, square, diamond, circular ring tablets followed. In addition, with the continuous development of preparations, due to the requirements of compound preparations and timed release preparations, special tablets such as double layer, triple layer and core coating are made, which need to be completed on special tablet press.
Rotary tablet press is a machine which is made of several pairs of die distributed on the turntable to make a circular lifting movement according to a certain track and press the granular material into tablet through the press wheel. And the stamping rod with the rotary table rotating speed ≥60m/min line press is called high-speed rotary tablet press, this high-speed rotary tablet press has a forced feeding mechanism, the machine is controlled by PLC, has the automatic adjustment of pressure, control the weight of the piece, eliminate the waste piece, print data, display fault shutdown and other functions, in addition to the control of the weight difference within a certain range, Quality problems such as missing Angle and loose lobe can be automatically identified and eliminated.
With the development of market demand, the scope of application of tablet press is more and more wide, no longer simply limited to the suppression of Chinese and Western medicine tablets, more widely suppressed health food, veterinary medicine tablets, chemical tablets: such as mothballs, washing blocks, smurf blocks, art powder, pesticide tablets, food tablets: chicken essence block, isatis root block, divine Qu tea block, compressed biscuits.
