    Types and advantages of tablet presses

    With the continuous development of the market economy, there are more and more commodities in the market that need to be pressed into powder or granular form. For example, Chinese and Western medicine tablets, camphor ball health balls, candies, food tablets, Banlangen blocks, and other products. A tablet press is a device that can quickly press granular or powdery raw materials into shape. Therefore, the demand for a tablet press is becoming more and more extensive.

    The history of tablet press

    Tablet presses first appeared in Europe and the United States and have a history of nearly a hundred years. The first tablet press machine introduced in China was in 1949, and it was the first equipment used to manufacture pharmaceutical tablets. After continuous R&D and improvement, the rotary tablet press has the function of automatic rotation and tablet compression. The compressed items are no longer limited to pharmaceutical tablets, but also sugar tablets, calcium tablets, coffee tablets, etc. Up to now, there are many specifications of the tablet press, the scope of application is wider, and the shapes of compression molding are numerous. A tablet press can press out round tablets, special-shaped tablets, double-layer tablets, ring tablets, packaged chips, etc. by changing different molding dies.

    Machine type

    The models can be divided into single-punch tablet presses, flower basket tablet presses, rotary tablet presses, sub-high-speed rotary tablet presses, fully automatic high-speed tablet presses, and rotary core-spun tablet presses.

    Single Punch Tablet Press

    The single-punch tablet press machine is a small desktop electric continuous tablet press machine, which can also be operated by hand. The extruded tablets have an average thickness and high gloss without polishing. Since the single-punch tablet press has only one pair of dies, it is called a single-punch tablet press; the filling depth of the material and the thickness of the tablet can be adjusted.

    The single-punch tablet press machine can press powder and granular raw materials into tablets and can be widely used in pharmaceutical factories, chemical factories, hospitals, scientific research units, laboratory trial production, and small batch production. The small single-punch tablet press machine is suitable for pressing Chinese medicine tablets, western medicine tablets, chewable tablets, calcium tablets, buccal tablets, spirulina tablets, milk tablets, candy tablets, effervescent tablets, mothballs (hygienic balls), aromatic tablets, taste blocks, disinfection tablets, catalysts, fertilizer tablets, pesticide tablets, button batteries, electronic components, metallurgical powder ceramic particles, etc. It is a small desktop electric (manual) continuous tableting machine, equipped with a pair of dies, the filling depth of the material, and the thickness of the tableting can be adjusted. Various shapes of molds can be provided according to customer requirements.

    Rotary tablet press

    Rotary tablet press machine is a machine that automatically rotates and continuously presses tablets. It is the basic equipment for processing various granular raw materials into tablets in pharmaceutical, chemical, food and other industrial sectors. The hopper part of the rotary tablet press is mainly used for material storage, and its lower part is connected with the forced feeder; the gear motor part of the rotary tablet press is the power source of the forced feed system. It mainly includes a three-phase/single-phase motor and a worm gear reducer. It is controlled by a frequency converter, and the output speed is adjustable. The lower part is connected to the forced feeder; the forced feeder of the rotary tablet press is mainly used to fill the material into each intermediate die hole on the turntable, thus completing the final task of the forced feeding system, so the forced feeder It is the core component of the entire forced feeding system.

    Advantages of Tablet Press

    The production principle of the tablet press is based on one-way compression of manual film compression, that is, the lower punch is stable while the upper punch is pressed. This method makes the tablet density non-uniform due to non-uniform force. Crack occurs. It is no longer only used to compress western medicine tablets, even veterinary medicine tablets, health food, chemical tablets. Powder direct compression is to sieve and mix the powder of the drug and suitable excipients separately, and directly compress it into tablets without granulation (wet granules or dry granules). Because of its simple process, no need for granulation and drying, energy saving and time saving, protection of drug stability, improvement of drug dissolution rate, and high degree of industrial automation, it is being increasingly used by pharmaceutical companies in various countries. Another advantage of powder direct compression technology is that it avoids the effects of heat and moisture. Tablets produced by powder direct tableting machine technology have good disintegration properties and excellent dispersion uniformity
