The cooling medium for drop pills generally uses dimethyl silicone oil, liquid paraffin, and other vegetable oils. After a period of use, due to the influence of indoor humidity and human intervention, a certain amount of water will be mixed in, making it cloudy and opaque, thereby affecting the roundness of the drop pill. The water leaked by human intervention can be solved by precipitation and release due to the high specific gravity of water. The most difficult problem is that the cooling medium absorbs water molecules dispersed in the medium in a dispersed state by lowering the working temperature. In addition, due to long-term use, the solid particles emitted during the molding and exhaust process of the dropping pills are also dispersed and floating in the medium, which exacerbates the turbidity of the medium. In order to solve the above problems, some manufacturers adopt high-density impurity filtration methods, but the effect is not good. The reason is that the removal of oil and drying of silica gel is also a more troublesome task. The principle of Buyuan Pharmaceutical Machinery Co., Ltd. through experiments is to pump the silicone oil used into a sealed oil storage tank. The tank heats the heat transfer oil with electricity, and then heats the medium to reduce the viscosity of the medium during heating, causing the water to evaporate and rise. The steam is then discharged through a vacuum pump to remove the water, and then pumped into an activated carbon filter and a 0.2um titanium alloy filter through a high-temperature resistant oil pump. After two pole filtration, it is discharged for cooling and ready for use. The device has a compact structure, high degree of automation control, and can set temperature and pressure arbitrarily, suitable for processing different media. Finally, the viscosity of silicone oil is measured and injected back into the dropping pill machine for reuse. Some manufacturers use boiling method, but due to lax temperature control, the medium is prone to gelatinization, which affects the roundness of the drop pills during the molding process.

Operation tip: Before using the drip pill equipment, it is necessary to master the operating principle of the equipment according to the instructions in the manual. If there are any doubts, please consult the manufacturer in a timely manner and do not hesitate

Operate the equipment in the given situation.

Operating instructions: First, turn on the coolant pump, then turn on the refrigeration unit, and at the same time, turn on the required heating device. When the required temperature reaches a stable value, add the dripping substance that has reached the dripping state

After entering the drip can and completing each drip, first turn off the heating and cooling system: observe that all the drip pills in the system have flowed out, and then turn off the cooling circulation system to prevent residual drip pills. Drip every time

After completion, residual substances must be removed, and all pipeline containers and coolant filters that have come into contact with the droplet before solidification must be cleaned.
