Hello everyone! We are Guangzhou Cleanroom Construction Co., Ltd. As a professional manufacturer of purification equipment, we are well aware of the importance of air - supply ceilings in the environment of purification workshops. Today, we will discuss the comparison and selection of different types of air - supply ceilings with you, helping you create an ideal purified space. I. High - Efficiency Air - Supply Outlet Type Air - Supply Ceiling 1. Structure and Principle The high - efficiency air - supply outlet type air - supply ceiling mainly consists of a static pressure box, a high - efficiency filter, and a diffuser plate. Air first enters the static pressure box and is evenly distributed inside. Then, it passes through the high - efficiency filter for high - precision filtration and is finally evenly sent into the room through the diffuser plate. This structure ensures that the air sent into the room has an extremely high cleanliness level. 2. Performance Characteristics High Cleanliness: The equipped high - efficiency filter can effectively filter tiny particles in the air. The filtration efficiency for particles with a particle size of ≥0.3μm can reach over 99.97%, which is very suitable for places with extremely high cleanliness requirements, such as purification workshops in the pharmaceutical and electronic chip manufacturing industries. Uniform Airflow Distribution: The design of the diffuser plate enables the air to be evenly diffused to every corner of the room, reducing the dead corners of indoor air flow and ensuring the consistency of indoor air cleanliness. 3. Application Scenarios It is suitable for production and research environments with extremely strict requirements for air quality, such as operating rooms and sterile laboratories. These places need to strictly control the number of dust particles and microorganisms in the air to ensure the success rate of surgeries or the accuracy of experimental results. II. Perforated Plate Type Air - Supply Ceiling 1. Structure and Principle The perforated plate type air - supply ceiling has small holes opened on a metal plate according to certain rules, and air is evenly sent into the room through these small holes. Its principle is based on the static pressure principle of air. By reasonably designing the aperture, hole spacing, and hole arrangement of the perforated plate, the uniform delivery of air is achieved. 2. Performance Characteristics Aesthetically Pleasing: The perforated plates come in various shapes and can be customized according to the interior decoration style, not only meeting the purification requirements but also enhancing the overall aesthetics of the room. Relatively Low Price: Compared with some air - supply ceilings with complex structures, the manufacturing process of the perforated plate type air - supply ceiling is relatively simple, with a lower cost, which can reduce the overall cost of the purification project to a certain extent. Limited Wind Speed Adjustment Range: Due to its structural characteristics, it is less flexible in adjusting the wind speed than some other types of air - supply ceilings, and its ability to precisely control the indoor air flow is slightly weaker. 3. Application Scenarios It is suitable for places with certain cleanliness requirements but are cost - sensitive, such as food processing workshops and ordinary electronic assembly workshops. These places need to ensure a certain air quality while also considering cost factors, and the perforated plate type air - supply ceiling is a more suitable choice. III. Swirl Diffuser Type Air - Supply Ceiling 1. Structure and Principle The air outlet of the swirl diffuser type air - supply ceiling is spiral - shaped. When the air is sent out from the air outlet, a swirling air flow is generated. This swirling air flow can quickly mix with the indoor air, making the indoor temperature and humidity distribution more uniform. At the same time, it can also effectively discharge the dirty air in the room. 2. Performance Characteristics Good Mixing Effect: The unique swirling air flow design can make the fresh air sent in fully mix with the indoor air in a short time, quickly improving the indoor air quality. Flexible Installation Height: Compared with other types of air - supply ceilings, the swirl diffuser type air - supply ceiling has relatively low requirements for the installation height and can also perform well in some places with limited space. Relatively High Noise: Since the air is sent out in a swirling manner, a certain amount of noise will be generated during operation. Sound insulation measures need to be considered when using it in environments with strict noise requirements. 3. Application Scenarios It is suitable for some places with high requirements for air mixing effects and temperature uniformity, such as large - scale industrial plants and stadiums. In these places, rapid air mixing and uniform temperature distribution are crucial for the comfort of personnel and the stability of the production process. When choosing an air - supply ceiling, multiple factors such as the cleanliness requirements of the place, budget, space characteristics, and noise control need to be comprehensively considered. Guangzhou Cleanroom Construction Co., Ltd. has a rich product series and a professional technical team, and can provide you with the most suitable air - supply ceiling solutions.

In the current booming development of the prefabricated vegetable industry, the rational layout of purification workshops is crucial for ensuring food safety and improving production efficiency. As Guangzhou Cleanroom Construction Co., Ltd., a professional manufacturer of purification equipment, we will explain the key points of the layout of prefabricated vegetable purification workshops today. I. Clarify the Purification Workshop Grade Prefabricated vegetable production workshops generally need to meet certain cleanliness standards, such as the common Class 100,000 purification standard. Different prefabricated vegetable categories and production processes have different requirements for cleanliness. For example, the purification requirements for ready - to - eat prefabricated vegetables are usually higher than those for ordinary prefabricated vegetables. Take the production workshop of a well - known brand's ready - to - eat salad prefabricated vegetables as an example. To ensure the freshness and safety of vegetables, its purification grade has reached Class 10,000. Clarifying the purification grade is the basis for subsequent layout, which is related to the selection and installation location of purification equipment. If the purification grade is not determined accurately, it may lead to excessive purification costs or failure to meet food safety requirements. II. Functional Area Division A. Raw Material Pretreatment Area This is the initial link of the workshop, used for receiving and preliminarily processing raw materials. This area should be close to the goods entrance to facilitate the transportation of raw materials. Special cleaning, sorting, peeling and other equipment should be set up, and the ground should be set with a drainage slope and floor drains to facilitate the discharge of sewage. A large - scale prefabricated vegetable enterprise installed automated cleaning equipment in the raw material pretreatment area, which can process hundreds of kilograms of vegetables per hour, greatly improving the cleaning efficiency. At the same time, through the reasonable setting of the drainage slope, the sewage can be discharged quickly, avoiding the problem of bacteria breeding due to water accumulation. B. Processing and Production Area According to the processing technology of prefabricated vegetables, different processing units are divided, such as the cooking area and the blending area. The passages between various processing units should be reasonably planned to ensure the smooth flow of personnel and materials. The placement of processing equipment should conform to the technological process to avoid cross - contamination. For example, in the cooking area, the placement of stoves should consider the transfer path of ingredients to avoid cross - contact between raw and cooked ingredients. At the same time, in the blending area, a special ingredient storage area should be set up to ensure the accuracy and hygiene of ingredients. C. Packaging Area This is a key area that directly affects the quality of prefabricated vegetable products. It is necessary to maintain a high level of cleanliness and be connected to the processing area through a transfer window. The packaging area should be equipped with complete air purification equipment, such as high - efficiency filters, to ensure the cleanliness of the packaging environment. A prefabricated vegetable enterprise installed a laminar flow hood in the packaging area, making the air cleanliness of the packaging area reach Class 100, effectively extending the shelf life of prefabricated vegetables. D. Personnel and Material Passages The personnel passage and the material passage should be strictly separated to avoid cross - contamination between personnel and materials. The personnel passage is equipped with a changing room, a hand - washing and disinfection room, etc., to ensure that personnel meet the hygiene standards when entering the workshop. The material passage is equipped with a material transfer window to disinfect the materials entering the workshop. In a prefabricated vegetable production workshop, personnel need to go through three - step changing and disinfection before entering the workshop to ensure that dust and bacteria on their bodies will not be brought into the workshop. At the same time, when materials enter the workshop through the transfer window, they will be disinfected by ultraviolet rays and ozone to ensure the hygiene and safety of materials. III. Purification Equipment Layout A. Air Purification Equipment High - efficiency air supply outlets are evenly arranged on the top of the workshop to ensure the uniform distribution and efficient filtration of air in the workshop. The air return outlets are set at the lower part of the workshop to form a reasonable air flow organization. At the same time, according to the workshop area and purification grade, an air purification unit with an appropriate air volume is configured. For example, a Class 100,000 purification workshop with an area of 1000 square meters needs to be equipped with an air purification unit with an air volume of 50,000 cubic meters per hour to ensure the air cleanliness in the workshop. B. Water Purification Equipment During the production process of prefabricated vegetables, the water consumption is large, and the water quality directly affects the product quality. The water purification equipment should be close to the water - using areas, such as the raw material pretreatment area and the processing and production area. Multistage filtration and disinfection processes are adopted to ensure that the production water meets the hygienic standards. A prefabricated vegetable enterprise adopted a water purification process of reverse osmosis + ultraviolet disinfection, so that the microbial and chemical indicators of the production water have reached the national drinking water standards, providing a strong guarantee for product quality. A reasonable layout of the prefabricated vegetable purification workshop is the key to ensuring the quality of prefabricated vegetables.

As Guangzhou Cleanroom Construction Co., Ltd., which is dedicated to the production of purification equipment, we deeply understand the significance of cleanrooms for numerous industries. In fields with extremely high requirements for the production environment, such as pharmaceuticals, food, and electronics, the cleanliness of cleanrooms and microbial detection are the core elements to ensure product quality and safety. I. The Importance of Cleanliness and Microbial Detection 1. Product Quality Assurance Take the manufacturing of electronic chips as an example. Tiny dust particles can cause chip short - circuits or other performance issues. In pharmaceutical production, microbial contamination directly threatens the safety and effectiveness of drugs. Ensuring that the cleanliness of the cleanroom meets the standards and strictly detecting microorganisms are the cornerstones of producing high - quality products. 2. Compliance with Regulatory Standards Countries and various industries have formulated strict cleanroom standards and microbial limit requirements. For example, in the pharmaceutical industry, it is necessary to follow the GMP (Good Manufacturing Practice) standards. Only by meeting these regulatory requirements can enterprises produce legally and compliantly. II. Cleanliness Detection Methods 1. Dust Particle Counter This is a commonly used device for detecting cleanliness. It can accurately measure the number of dust particles of different particle sizes in the air through the principle of light scattering. According to the level requirements of the cleanroom, the number of particles per cubic meter of air is counted to determine whether it meets the corresponding cleanliness level. 2. Aerobic Colony Counter Although it is mainly used for microbial detection, it can also reflect cleanliness from the side. It collects the microorganisms floating in the air onto Petri dishes or culture media by extracting a certain volume of air. After cultivation, the number of colonies is counted to understand the content of microorganisms in the air, indirectly reflecting the cleanliness situation. III. Microbial Detection Methods 1. Settling Plate Method Place Petri dishes filled with culture media at specific positions in the cleanroom. Open the lids and expose them for a certain period of time, allowing the microorganisms in the air to naturally settle onto the culture media. Then, cultivate and count the colonies. This is a simple and intuitive detection method that can detect the microbial contamination in the air in a stationary state. 2. Swab Sampling Method For the microbial detection of the surfaces of equipment, walls, and other objects, the swab sampling method is commonly used. Dip a sterile cotton swab in an appropriate sampling solution, wipe the surface of the object, and then put the cotton swab into the culture medium for cultivation. The degree of microbial contamination on the object surface is judged by counting. IV. The Interrelationship between Cleanliness and Microbial Detection In a cleanroom with high cleanliness, the possibility of the presence of microorganisms is relatively low. Since dust particles may carry microorganisms, reducing the number of dust particles also reduces the carriers of microorganisms. The results of microbial detection can also reflect the maintenance of cleanliness. If the microorganisms exceed the standard, it is likely that there are problems with the purification system of the cleanroom or improper operations by personnel, affecting the cleanliness. V.
