It features intelligent spray and water circulation systems which reduce water consumption and energy usage by up to 40% for you while maintaining cleaning effectiveness.
Wide Applicability
The machines withstand strong acidic or alkaline detergents and high-temperature operations, catering to pharmaceutical cleaning needs across diverse process environments.
Stable Performance
Its system precisely controls critical parameters including detergent concentration, water temperature, water pressure, cleaning duration, and flow rate.This can keep consistent cleaning results with a deviation of less than ±2% per cycle.
Workflow of Pharmaceutical Washing Machines
Pre-Rinsing
The equipment first rinses the surface of the instruments with flowing purified water at room temperature, effectively removing most loosely adhering contaminants. This step lays the foundation for subsequent deep cleaning to increase overall cleaning efficiency.
Cleaning
It thoroughly removes stubborn residues remaining after pre-treatment by a dual mechanism of “cleaning agent + physical action (spraying, ultrasonics)”. You can select alkaline, enzymatic, or surfactant detergents based on residue type. Spray pressure is typically controlled at 2–5 bar to ensure removal of stubborn residues without damaging surfaces at the same time.
Rinsing
Finishing primary cleaning, the system performs multi-stage rinsing to eliminate residual detergents (like sodium hydroxide, enzymes) and dissolved impurities. This prevents reactions between residual detergents and subsequent chemicals, or potential harm to personnel.
Drying
The final stage adopts hot air to completely remove moisture and achieve thorough instrument dryness. Common methods like hot air circulation, sterile compressed air drying, and vacuum drying are automatically chosen based on the shape and material of the items being cleaned.
Types of Pharmaceutical Washing Machines
Fully Automatic Pharmaceutical Washing Machine
This equipment shows a high degree of automation and it has capability to automatically complete pre-wash, cleaning, rinsing, and drying operations. Simply load the equipment and start the program, and the system will execute with a single button press. The fully automatic pharmaceutical washers are the preferred choice for pharmaceutical companies with stringent production cycle and cleaning validation requirements, particularly in medium to large-scale production lines where they significantly decrease manual intervention and cross-contamination risks.
Semi-automatic Pharmaceutical Washing Machine
Semi-automatic equipment can automatically perform part of the cleaning process, but it needs manual intervention for drying, cleaning agent preparation, and transfer operations. For smaller production scales, this type equipment can meet daily cleaning needs with a lower investment while maintaining good flexibility and cost control.
Pharmaceutical Instrument Washing Machine
This type is specifically designed for processing pharmaceutical instruments such as ampoules, test tubes, and filling needles. Its system realizes targeted cleaning based on the shape and material of each instrument. It effectively removes contaminants from surfaces to ensure instrument cleanliness. By using
specialized spray nozzles and an adjustable flow injection system, the machines thoroughly eliminate trace residues to keep instrument cleanliness and reusability.
Pharmaceutical Equipment Washing Machine
The pharmaceutical equipment washing machine is primarily designed for cleaning large equipment components such as reactor agitators and tablet press dies. The type employs powerful high-pressure spray and multi-angle rotating cleaning functions, enabling thorough decontamination of internal surfaces and hard-to-reach areas.
Pharmaceutical Sterile Washing Machine
This equipment is designed for sterile manufacturing. After washing, it can be dried via hot air or vacuum drying to meet sterility requirements. If your facility manufactures injectables, eye drops, or other sterile preparations, this equipment helps you consistently achieve cleanliness level control and validate compliance.
Pharmaceutical Tunnel Washing Machine
A pharmaceutical tunnel washing machine takes a tunnel-style structure where items to be cleaned move through the tunnel via a conveyor belt or other transport device. They sequentially pass through multiple zones including pre-wash, main wash, rinse, and drying, achieving fully automated continuous cleaning. For large-scale, batch, or continuous instrument cleaning needs, this design significantly boosts production throughput while reducing per-item cleaning costs.
Cleaning in Place System (CIP System)
The CIP system can be integrated into pharmaceutical production equipment, reaching automated cleaning of the entire production system without disassembly. It rapidly removes production residues without disrupting production schedules and minimizing equipment downtime.
What Can Pharmaceutical Washing Machines Clean?
Pharmaceutical washing machines are suitable for cleaning instruments and equipment used in various experimental, production, and transportation processes. They meet the cleaning needs of pharmaceutical factories of different scales.
- Instruments: Pharmaceutical washing machines can efficiently clean commonly used experimental and production instruments such as medicine spoons, samplers, mix tanks and filter funnels.
- Equipment: Machines use high-pressure spraying and precise temperature control systems, they effectively remove residual drug powders, oils, or polymer deposits to clean parts like syringes, tablet press dies, mixing blades, and stainless steel trays.
- Containers: Its cleaning system automatically adjusts spray angles and flow rates based on container shape. It effortlessly handles cleaning requirements for ampoules, glass tubes, plastic barrels, and other materials and sizes.
Consideration About Choosing Pharmaceutical Washing Machines
Washing Object Types
Before selecting a pharmaceutical cleaning machine, you must clear the type, size, and material of the cleaning objects. Different materials and sizes require distinct cleaning parameters.
For example, large equipment components (such as reactor agitators or tablet press dies) need the washing machines with larger chamber capacities to ensure thorough cleaning. If you wash the plastic containers or utensils, it is recommended that you select equipment compatible with neutral cleaning agents to prevent plastic degradation or surface damage caused by acidic or alkaline cleaning.
Type of Contaminants
Contaminant type is a key determinant of cleaning methodology. Common pharmaceutical process contaminants include oils, powders, syrups, and biological residues. Selecting a pharmaceutical cleaning machine tailored to the contaminant type can reach more efficient cleaning.
When production involves high-viscosity materials or residues prone to crystallization, models with alkaline cleaning and ultrasonic capabilities are recommended. Because these models adopt the dual action of chemical dissolution and mechanical vibration to rapidly remove stubborn contaminants, which reduces the need for secondary cleaning and improves overall efficiency.
Washing Capacity and Cleaning Cycle
It is necessary to take your required cleaning cycle and volume into considerations when selecting pharmaceutical cleaning equipment. For instance, if you need to process hundreds of items per cycle or frequently switch cleaning batches, a fully automated pharmaceutical washer is more suitable for you. It automatically completes pre-wash, main wash, rinse, and drying to significantly boost cleaning efficiency while reducing labor costs.
