DG系列干法制粒機(jī)

詳細(xì)介紹

干法制粒機(jī)時利用物料本身的結(jié)晶水，依靠機(jī)械擠壓原理，直接對原料粉末不加粘合劑及水進(jìn)行壓片成型—>壓片成型—>片狀物粗碎—>造粒成型為一體的制粒設(shè)備。制成不規(guī)則狀顆粒，完成從粉體至顆粒的物理變化過程。干法制粒機(jī)具有工藝簡單、生產(chǎn)批量大、易于清潔維護(hù)等特點(diǎn)。廣泛用于醫(yī)藥、食品、化工等行業(yè)。
干法制粒機(jī)主要分為制粒裝置和動力裝置，兩部分在空間上隔離。制粒裝置又主要分為10個模塊：1.水平喂料系統(tǒng)2.螺桿進(jìn)料系統(tǒng)3.輥壓系統(tǒng)，壓輥4.預(yù)防系統(tǒng)5.破碎系統(tǒng)6.取樣口7.兩級篩分制粒系統(tǒng)8.取樣口9.顆粒出口10.機(jī)架。
干法制粒過程中輥壓過程，干粉狀或微細(xì)晶體狀原料被壓輥擠壓成薄片，并且薄片的質(zhì)量決定了最終用的質(zhì)量。干法制粒機(jī)使用了輥壓
控制技術(shù)，該設(shè)備的控制設(shè)備能夠調(diào)節(jié)不同物料以及同一物料不同批次之間的任何物理性質(zhì)的波動（如局部的不均勻），使得干法制粒的工藝參數(shù)（如處理量、片狀密度、輥壓壓力、速度等）能夠被精確、重復(fù)地調(diào)整，從而高效地生產(chǎn)出高質(zhì)量的顆粒。
此外，干法制粒機(jī)進(jìn)料和輥壓處理過程之間有明確的、模塊化的分離，螺桿進(jìn)料系統(tǒng)直接將粉末送至壓輥，使得輥壓過程中不會影響螺桿進(jìn)料系統(tǒng)的初步壓制過程。
干法制粒機(jī)主要表現(xiàn)在對不同物料的適應(yīng)性好、結(jié)構(gòu)緊湊、拆裝和清洗速度、一次成型率高、成品顆粒的質(zhì)量包括密度、硬度、溶解度、顏色存在較小差異、自動化程度高。
DG系列干法制粒機(jī)—設(shè)備特點(diǎn)
1.整機(jī)懸臂式設(shè)計，具有觀察方便、便于清理的特點(diǎn)。將加工區(qū)與動力傳動區(qū)隔離且外形整潔，拆裝清洗簡便，實(shí)現(xiàn)了從粉體到顆粒的潔凈密閉式生產(chǎn)。
2.壓片傳動結(jié)構(gòu)采用油封、硅膠壓輥專用密封空氣隔離（漏軸結(jié)構(gòu)）密封，有效做到傳動部分與工作部分的安全隔離，且拆裝、保養(yǎng)、更換便捷。
3.采用雙螺桿送料，在送料末端有真空脫氣裝置，供料均勻且密實(shí)，提高成片強(qiáng)度的均勻性及成品率。
水冷式壓輥，進(jìn)出口結(jié)構(gòu)為內(nèi)置式，試物料在擠壓過程時不會升溫，影響物料性能。
4采用PLC觸屏智能化控制，一鍵啟動，一鍵停止，可靠性高，操作簡單。壓輪間隙可調(diào)，傳感器有效監(jiān)控油壓間隙距離等參數(shù)
5可選配置壓輪水冷卻系統(tǒng)、除塵回收系統(tǒng) 、震動分篩功能
壓輪分為網(wǎng)紋，直紋，光輪三種適應(yīng)不同物料。
6系統(tǒng)結(jié)構(gòu)設(shè)計合理，人機(jī)界面安全、可靠、快捷、工藝流程配比合理，生產(chǎn)運(yùn)行可靠。整機(jī)全不銹鋼制作，接觸物料部分可為316材質(zhì)，符合GMP和FDA要求。
In the dry granulator, the crystal water of the material itself is used, relying on the principle of mechanical extrusion, to directly compress the raw material powder without any binder and water—>tabletting and molding—>coarse flakes—>granulation and molding As an integrated granulating equipment. It is made into irregular particles to complete the physical change process from powder to particle. Dry granulator has the characteristics of simple process, large production batch, easy to clean and maintain. It is widely used in medicine, food, chemical and other industries.
The dry granulator is mainly divided into a granulating device and a power device, and the two parts are completely separated in space. The granulating device is mainly divided into 10 modules: 1. Horizontal feeding system 2. Screw feeding system 3. Rolling system, pressure roller 4. Prevention system 5. Crushing system 6. Sampling port 7. Two-stage screening system Granule system 8. Sampling port 9. Granule outlet 10. Rack.
During the rolling process of dry granulation, the dry powder or fine crystalline raw material is squeezed into flakes by the pressing roller, and the quality of the flakes determines the quality of the final use. The dry granulator uses the latest roll press
Control technology, the control equipment of this equipment can adjust any physical property fluctuations (such as local unevenness) between different materials and different batches of the same material, so that the process parameters of dry granulation (such as throughput, flake density, Rolling pressure, speed, etc.) can be accurately and repeatedly adjusted to efficiently produce
high-quality pellets.
In addition, there is a clear and modular separation between the feed of the dry granulator and the rolling process. The screw feeding system directly sends the powder to the pressing roller, so that the initial process of the screw feeding system will not be affected during the rolling process. Suppressing process.
Dry granulator is mainly manifested in its good adaptability to different materials, compact structure, high speed of disassembly and cleaning, high one-time molding rate, small differences in the quality of finished particles including density, hardness, solubility, color, and high degree of automation.
DG series dry granulator—equipment features
1. The cantilever design of the whole machine has the characteristics of convenient observation and easy cleaning. The processing area is completely isolated from the power transmission area and the appearance is neat, easy to disassemble and clean, and realize the clean and closed production from powder to granule.
2. The sheet-pressing transmission structure adopts oil seal and silicone pressure roller special sealing air isolation (leakage shaft structure) to effectively isolate the transmission part and the working part, and it is convenient to disassemble, maintain and replace.
3. It adopts twin-screw feeding and a vacuum degassing device at the end of the feeding. The feeding is uniform and dense, which improves the uniformity of the strength of the sheet and the yield.
The water-cooled pressure roller has a built-in inlet and outlet structure, and the test material will not heat up during the extrusion process, which will affect the material performance.
4It adopts PLC touch screen intelligent control, one key to start, one key to stop, high reliability and simple operation. The pressure roller gap is adjustable, and the sensor effectively monitors the oil pressure gap distance and other parameters
5 Optional roller water cooling system, dust removal and recovery system, vibration screening function
The pressure wheel is divided into three types: net grain, straight grain and smooth wheel to adapt to different materials.
6 The system structure design is reasonable, the man-machine interface is safe, reliable, and fast, the process flow ratio is reasonable, and the production operation is reliable. The whole machine is made of stainless steel, and the contact material part can be made of 316 material, which meets GMP and FDA requirements
