本機(jī)用以將各種顆粒狀原料壓制成片狀，其zui大優(yōu)點是除圓形片外還能壓制各種幾何形狀的異形片、雙層片、環(huán)形片及雙面刻字片。轉(zhuǎn)盤上可裝21付活絡(luò)式?jīng)_模，旋轉(zhuǎn)一周即可壓制21片。壓片時轉(zhuǎn)盤的速度，物料的充填深度、壓片厚度均可調(diào)節(jié)，還可以選片看樣，壓片的壓力是由液壓系統(tǒng)設(shè)定的，并附有壓力表顯示，液壓系統(tǒng)內(nèi)配有過載保護(hù)裝置，在壓力過載時能自動停機(jī)，避免機(jī)件的損壞。
　　ZPW21A、ZPW21B是按藥品GMP要求設(shè)計的新機(jī)型，壓制室采用四開門有機(jī)玻璃封閉結(jié)構(gòu)，與外界環(huán)境隔離，室內(nèi)與物料接觸的各構(gòu)件均采用不銹鋼制成或者表面經(jīng)過特殊防腐處理，避免物料受污染提高片劑質(zhì)量和方便清潔。
　　ZPW21B是ZPW21A的改進(jìn)型產(chǎn)品，外圍全不銹鋼。

　　This machine is designed for pressing tablets from various kinds of granular materials.As its feature,the machine can press not only round tablets but also different geometrical shape tablets.Double-layered and annular tablets.The tablets may have the impressed letters on both sides.The turret carries 21 sets of movable-punches and dies.So 21 tablets will be pressed for each revolution of the turret.During operation ,the depth of the filling material and the thickness of the tablets can be adjusted.the pressure for tablet pressing is set by the hydraulic drive system.a pressure gauge is attaches to the system to show the pressure value.A overload protection unit is in cluded the system to avoid the damage of the punches and apparatus.When overload occurs.The machine stoops automatically.
　　New type ZPW21A ZPW21B is desinged to meet GMP standard .An inproved type of ZPW21.Its pressing area is sealed with four polymethyl methacrylate doors to be isolated with outside environment.The parts contact the material are made of stainless steel or their surface is specially antisepticized to avoide pollution.
　　ZPW21B is an inproued uersion of ZPW21A.
