Dispensing booth:

A dispensing booth, also known as a powder containment booth or powder dispensing booth, is a specialized enclosure used in pharmaceutical, chemical, and other industries for handling and dispensing powders, granules, or other fine materials. It provides a controlled environment to minimize the risk of contamination and ensure worker safety during powder handling processes.

Here are some key features and functions of a dispensing booth:

  1. Enclosure and Construction: A dispensing booth is typically an enclosed structure with walls, ceiling, and a floor. It is constructed using materials that are resistant to chemicals and easy to clean, such as stainless steel or powder-coated steel. The booth is designed to provide a sealed and controlled environment to prevent the escape of powders and contaminants.
  2. Airflow Control: Dispensing booths utilize a controlled airflow system to maintain a clean and safe working environment. This usually involves a combination of supply air and exhaust air systems. The supply air is filtered to remove particulates, and the exhaust air is typically filtered to capture any airborne particles or contaminants generated during the dispensing process.
  3. Filtration System: Dispensing booths incorporate high-efficiency particulate air (HEPA) filters to capture airborne particles and maintain clean air within the enclosure. HEPA filters have a high efficiency in removing particles down to 0.3 micrometers in size. Some booths may also have additional filters, such as activated carbon filters, to capture odors or hazardous substances.
  4. Work Surface and Lighting: A dispensing booth is equipped with a smooth and easily cleanable work surface, often made of stainless steel or other non-porous materials. The work surface provides a dedicated area for powder handling, weighing, and dispensing activities. Adequate lighting is provided to ensure proper visibility during the process.
  5. Operator Safety: Dispensing booths prioritize operator safety by incorporating safety features such as protective barriers, gloves, or sleeves attached to the glove ports, and interlocking doors to prevent accidental exposure to hazardous materials. Some booths may also have options for local exhaust ventilation to further enhance worker protection.
  6. Control Panel: The booth may include a control panel that allows operators to control airflow, adjust lighting, and monitor system parameters such as filter condition, airflow velocity, and pressure differentials. The control panel provides flexibility and ensures the booth operates at the desired specifications.

Dispensing booths are crucial in environments where the handling of powders or fine materials can pose health risks or contamination hazards. They are commonly used in pharmaceutical manufacturing, chemical laboratories, research facilities, and other industries that require precise and controlled powder dispensing processes.

Regular maintenance and adherence to safety protocols are essential for the effective operation of dispensing booths. This includes routine filter replacement, cleaning of the work surface, and following proper procedures for decontamination and waste disposal. Operator training on the safe use of the booth and proper handling of powders is also crucial to maintain a safe working environment.
