The experimental pill dropping machine consists of four systems, including the drug dispensing and supply system, the circulating refrigeration system, the dynamic dripping collection system, and the PLC and touch screen control system. Let's take a look at the system composition and function of the experimental pill dropping machine.
1. Drug dispensing supply system: It consists of insulation layer, heating layer, seasoning tank, electric deceleration mixer, oil bath circulating heating pump, automatic output switch for liquid medicine, automatic spray cleaning device, compressed air conveying mechanism, etc. Function: Put the medicinal liquid and the base into the seasoning tank, make the mixed medicinal liquid of the dripping pills by heating and stirring, and then transport it into the dripping tank by compressed air.
2. Circulating refrigeration system: In order to ensure the forming of the drop pills, avoid the heat of dripping and the heat of the cooling column heating plate, so that the temperature of the cooling liquid is not affected, the imported combined refrigeration unit is used, and the refrigeration unit is controlled by a titanium alloy refrigerator. The temperature of the coolant in the box ensures the smooth forming of the drop pills.
3. Dynamic dripping collection system: The liquid level in the dripping tank is connected with the feeding system through the liquid sensor control, so that the dripping tank can maintain a certain liquid level. When dripping, the medicinal liquid is dripped into the cooling liquid by the dripper, and a heater is installed on the upper part of the cooling column, which reduces the temperature gradient of the medicinal drop and makes the medicinal drop moderately and fully shrink into a pill under the action of surface tension. Make the drop pill shape smooth and the pill weight is uniform. A linear pressure sensor is installed in the cooling column, and the flow rate of the infusion pump is controlled by frequency conversion speed regulation, so that the dynamic balance of the liquid level is maintained during the collection process of the coolant. In addition, the cooling column has a lifting function to facilitate the installation of the dripper and the dripping distance from the dripper to the liquid surface suitable for different liquid medicines.
4. PLC and touch screen control system: The touch screen computer control technology is adopted to realize the automatic production of the whole machine.
The experimental pill dropping machine is generally used in pharmaceutical preparations, health products, food and chemical products and other industries. An industrialized pill-dropping machine covers multi-disciplinary professional design, pharmaceutical engineering, refrigeration engineering, fluid mechanics, electrical automation, mechanical design, hydraulic and transmission and other multi-disciplinary technologies.
