在药品丸片剂的包衣工序中,为了使粉浆和糖浆中的水份迅速蒸发完,达到包衣的目的,必须对包衣的丸片剂表面进行不断的加热。我们制成了四台远红外电炉,用于丸片剂的包衣工序的加热。经过五年多的使用,证明远红外电炉使用时间长,生产安全。平均每年四台电炉共节电为二万三千多度电,减少炉丝费用开支为一千六百多元。远红外电炉的制作取一块经远红外涂料处理过的长320mm,宽150mm,厚20mm的碳化硅板,用一条1.5kw的普通电炉丝,盘绕在该板槽中,再用0.5～1mm厚的铝皮制成深15mm,长321mm,宽151mm的铝盒(即铝反射板)。再把装有电炉丝的碳化硅板,其炉丝暴露的一面装入铝合内,留出接线部分,其余完全封闭。依法制作三块,然后根据糖衣锅的大小,按示意图排成
In the coating process of the pharmaceutical pill tablet, in order to quickly evaporate the moisture in the slurry and the syrup, the surface of the coated pill tablet must be continuously heated for the purpose of coating. We have made four far-infrared furnaces for the heating of the pilling process. After more than five years of use, it proved that the far-infrared furnace has a long service life and production safety. On average, each of the four electric furnaces saves more than 23,000 kWh of electricity each year, reducing the cost of furnace wires by more than 1600 yuan. Preparation of Far-infrared Furnace Take a piece of silicon carbide plate with 320mm long, 150mm wide, and 20mm thick treated with far-infrared coating. Use a 1.5kw electric wire and wrap it in the plate groove. Use 0.5 to 1mm thick. The aluminum skin is made of an aluminum box (ie, aluminum reflector) with a depth of 15 mm, a length of 321 mm, and a width of 151 mm. Then put the silicon carbide plate with electric wire, the exposed side of the furnace wire into the aluminum alloy, leaving the wiring part, the rest completely closed. Make three pieces according to the law, then arrange according to the size of the sugar pan according to the schematic diagram
