Fully automatic rubber plug cleaning machine

Product Introduction: The rubber stopper cleaning machine, hence the name Siyi, is a machine used to clean rubber stoppers, generally used in the pharmaceutical industry. With the increasing requirements of GMP, the pharmaceutical industry attaches more and more importance to the cleaning of rubber stoppers. Rubber stopper cleaning has gone through a long process from manual cleaning to fully automatic cleaning

The rubber stopper cleaning machine, as the name suggests, is a machine used to clean rubber stoppers. It is generally used in the pharmaceutical industry. With the increasing requirements of GMP, the pharmaceutical industry pays more and more attention to the cleaning of rubber stoppers. Rubber stopper cleaning has gone through a long process from manual cleaning by Tian Zao to fully automatic cleaning.

At the beginning of the field, people started with manual cleaning because their understanding of rubber stoppers was limited, and manual cleaning did not require complex equipment, only simple tools. Due to its simple operation, people affirmed its cleaning function. This method has been maintained for a long time. But gradually people realized the limitations of manual cleaning, such as high energy consumption, long operation time, and unstable cleaning quality. So, innovation began, using mechanical stirring for cleaning, characterized by:; The equipment is simple, the cleaning quality is relatively stable, and the labor intensity of operators is reduced.

essential information:

However, due to the characteristics of mechanical stirring and cleaning, the cleaning degree of the rubber stopper is always not high. And the quality difference is also quite large. Upon investigation, it was found that the relative movement speed of the rubber stopper in water was too fast, resulting in an increase in the coefficient of friction with the cleaning container wall and damage to the surface of the rubber stopper due to collision with the stirring impeller. People began to use spray and rinse methods for cleaning rubber plugs, which lasted for a long time. However, new problems were discovered. Due to the geometric shape characteristics of rubber plugs, it is always difficult to thoroughly clean the umbilical area, and the cleaning efficiency is not high and time-consuming. Subsequently, various methods for cleaning rubber plugs emerged one after another, with the more typical ones being 'vacuum defoaming' and 'soda water impact'

They have obvious characteristics, high cleaning efficiency, short time, and outstanding field performance; The cleaning process has achieved almost no damage to the surface of the rubber plug, so these two methods are called non-destructive cleaning methods. Its working principle is:;

Vacuum defoaming refers to the process where small bubbles adhere to the edges of the adhesive particles due to the hydrophobicity of the rubber plug surface and the tension of water when the rubber plug enters water. By using vacuum, the bubbles adhered to the rubber plug are defoamed, causing the particles and impurities adhered to the rubber plug to detach from the surface and disperse into the water.

Soda impact refers to the use of high-speed airflow to impact a rubber plug immersed in water. When the rubber plug is subjected to instantaneous impact and pressure changes, it causes a change in the direction of its movement and the affected area. This results in vibration of the rubber plug, causing particles and impurities adhering to its surface to be repeatedly and continuously shaken off and carried away by the water flow. Subsequently, the water rapidly replenished and changed around the rubber stopper in a vortex, further playing a role in pulling away the particles and impurities adhered to the surface of the rubber stopper, and the rubber stopper was cleaned in this process.

Workflow:

The fully automatic aluminum cover cleaning and drying machine is designed and manufactured by our factory's researchers in accordance with the "GMP" standards and mechatronics integration requirements of GUO's pharmaceutical industry. Cleaning, drying, and sterilization are completed in the same enclosed compartment, eliminating cross contamination. It is a specialized equipment for aluminum lid washing in the pharmaceutical industry.

The inner components of this device are made of 316 stainless steel material, and the outer shell is made of 304 stainless steel material. The main supporting parts and electronic components are all imported products, and special materials are used for pressure resistance, high temperature ultrasonic resistance, bearings, seals, and gaskets. The aluminum cover treatment of the product adopts manual feeding, ultrasonic cleaning, hot circulation air sterilization, drying, and spiral automatic discharge processes. Aluminum caps are washed, sterilized, dried, and automatically discharged through multiple technologies such as strong spraying, slow rolling, and ultrasonic waves. The entire process is automatically operated under the control of a PLC controller, without intermediate sequence switching or cross contamination. This machine can dynamically display the operating status of each process on the monitor, intuitively understanding the operation of the unit. The temperature of each process is automatically recorded by the recorder for filing, reference, and printing. The entire process has a high degree of automation, low labor intensity, easy operation, energy saving, good quality in handling aluminum caps, and excellent technical performance. It is the preferred equipment for aluminum cap cleaning in the pharmaceutical industry.

2、 Operation process

The aluminum cover is fed into the cleaning bucket through the feeding port, and the feeding and water inlet can be carried out simultaneously. When the water level reaches the specified height, the water level sensor will act and automatically stop the water inlet. Clean after the water inlet feeding is completed. While rotating the drum, open the auxiliary inlet to discharge the floating dirt from the overflow outlet, and clean it at the same time. The cleaning time can be preset by the touch screen. When the cleaning time is up, reset and open the drain solenoid valve to drain the water, then close the drain solenoid valve and refill the water for fine cleaning. During the fine cleaning process, ultrasonic waves will automatically turn on, water will circulate and spray, the drum will rotate, and the inlet water will be turned on. After finishing the cleaning, open the drain solenoid valve and drain the liquid again. After cleaning, dry and sterilize. After passing the inspection, press the discharge button to discharge the material.
