Laboratory drip pill machine, Niu Zhangzhi pill making machine

This equipment is a drop pill preparation machine based on polyethylene glycol as the matrix (i.e., drop pill preparation material) and methyl silicone oil as the condensing medium. It is the successor of our factoryDW-35A small drop pill machine developed specifically for experimental trial production of drop pills after the production of drop pill equipment; It has the characteristics of small volume, good roundness, uniform size, and easy cleaning and maintenance of drip pills. After the main and spreading materials are melted, they can be directly added to the dropping pill machine to make pills. Due to the simple production process and equipment of dropping pills, there is no dust flying in the production process, which is particularly suitable for the production of toxic and harmful drugs. It can replace tablets and other dosage forms within a certain range

three 、 Main technical parameters of the equipment

4、 Working principle

medicine、After the material is melted, it is added to the material tank through the feeding port on the dropping pill machine. The material tank is immersed in an insulated oil tank, and the tank is filled with40The temperature of the engine oil is generally controlled at80-90The temperature control system consists of a platinum thermistor, a temperature controller, and a thyristor voltage regulator.

The material liquid intermittently drips into the cooling bucket from the droplet head and is rapidly cooled by silicone oil. The dropping pills become round spherical bodies due to surface tension and sink to the bottom of the cooling bucket. After the material is dripped, the cooling bucket can be pulled out and the dropping pills can be collected from the discharge port.

five Equipment installation and use

The installation of the equipment is relatively simple, just place it on a flat floor. The height of the cooling bucket can be adjusted by the handwheel to form a relatively round drip pill. After each drip pill, the material tank and drip head should be cleaned with hot water. For easy cleaning, the fixed handle can be released to rotate the cooling bucket out.

The equipment should have reliable grounding to ensure safety.

6、 Precautions

1The amount of methyl silicone oil added is based on the distance from the barrel mouth80mmAs appropriate,

2The fuel tank must be filled with fuel before heating to avoid burning out the electric heating rod.

3Regularly check the tightness of each component to prevent oil leakage.

DW-1Operation Process Instructions for Type Dripping Pills Machine

1 Turn on the machine, check the condition of each part of the machine, install the selected dropper, and inject heating oil（40Number of engine oils).

2 Connect the power supply（220V）Set the temperature of the material tank.

3 Prepare the liquid according to the prescription, heat it to the desired temperature, and at the same time201-50(or100Methyl silicone oil is cooled to5About degree.

4 use70Clean the material tank with hot water at around degrees Celsius, and drain the water from the dropper through the valve (for cleaning and preheating).

5 Close the valve and add the liquid into the material tank for insulation. Add frozen methyl silicone oil into the cooling cylinder.

6 Adjust the height of the cooling cylinder, and ensure that the distance between the liquid level and the bottom of the dropper is about2cmSlowly open the discharge valve to evenly drip the medicine into the cooling cylinder.

7 After the liquid droplets are finished, open the drain valve at the bottom of the cooling cylinder to allow the pills and coolant to flow out together. Collect pills.
