Quick cage cleaning machineIt is the core equipment in the experimental animal feeding process, and its cleaning effect directly affects the sterility of the cage, which in turn affects the quality of SPF grade animal feeding and the reliability of experimental data. However, the device brands in the market are complex and have different parameters, which can easily lead to misunderstandings such as "only looking at price" and "ignoring adaptability" when selecting. This article combines practical application scenarios to sort out the core avoidance points for laboratory selection, providing practical reference for precise selection.

Avoiding pitfall point one: blindly pursuing "high speed" and neglecting cleaning uniformity. Some buyers consider rotational speed as the core indicator, believing that the higher the rotational speed, the better the washing effect. In fact, if the spray system design of the equipment is not reasonable, high speed may lead to excessive local flushing and inadequate cleaning in some areas, especially in the corners and gaps of the cage box, which are prone to residual excrement and microorganisms. When selecting, special attention should be paid to the spray structure, and equipment with 360 ° rotating spray arms and multi-directional nozzle designs should be given priority. At the same time, suppliers are required to provide cleaning effect testing reports to confirm that the cleaning qualification rate for key parts such as the inner wall and grid of the cage box reaches 100%.

Avoiding pitfall point 2: Neglecting the corrosion resistance of materials can lead to a short lifespan of the equipment. The cleaning of experimental cages often requires the use of neutral or weakly alkaline cleaning agents, and some highly polluting cages also require high-temperature disinfection. If the inner tank and spray arm of the equipment are made of ordinary stainless steel material, long-term use is prone to rusting and deformation, which not only affects cleaning hygiene but also shortens the service life of the equipment. When selecting, it is necessary to confirm the material of the core components of the equipment, with priority given to 304 or 316L stainless steel, and the inner liner needs to be polished with no weld dead corners, which can resist the corrosion of cleaning agents and facilitate cleaning and maintenance, avoiding increased replacement costs due to material issues in the later stage.

Avoiding pitfall point three: Neglecting the adaptability of production capacity can result in resource waste or insufficient efficiency. There is a significant difference in the amount of cages used in different laboratories. Blindly purchasing large capacity equipment can lead to high energy consumption and water waste during a single cleaning process; If equipment with insufficient production capacity is chosen, problems such as untimely cleaning and accumulation of pollution may arise. Before selecting, it is necessary to accurately calculate the daily cleaning volume of the cage box, and determine the equipment specifications based on the equipment's single cleaning capacity and cleaning cycle (usually the cycle of a fast cleaning machine is 15-30 minutes). For example, a laboratory that cleans 500 cages per day can choose equipment that cleans 50 cages at a time with a cycle of 20 minutes, balancing efficiency and energy consumption.

Avoiding pitfall point four: Neglecting disinfection and sterilization functions, and neglecting key protective measures. partQuick cage cleaning machineOnly focusing on cleaning function, the disinfection module design is rudimentary and cannot meet the sterile requirements of SPF laboratory. When selecting, it is necessary to confirm that the equipment has a complete integration of cleaning, disinfection, and drying functions. The preferred disinfection method is high temperature and high pressure (temperature ≥ 85 ℃, pressure ≥ 0.1MPa) or ultraviolet disinfection, and the disinfection time can be adjusted; At the same time, attention should be paid to the drying effect to avoid the growth of bacteria due to residual moisture after cleaning the cage box. It is recommended to choose equipment with hot air circulation drying function to ensure that the moisture content of the cage box after removal is ≤ 5%.

Avoiding pitfall point five: Neglecting after-sales and compliance, there is no guarantee for later operation and maintenance. Some niche brand equipment is low-priced, but lacks a comprehensive after-sales system, and repairs are not timely after malfunctions occur. They are also unable to provide testing reports that comply with the "Technical Specifications for Laboratory Animal Facility Construction", which may affect laboratory qualification review. When selecting, priority should be given to brands with good market reputation and a complete after-sales network. Suppliers are required to provide equipment compliance certificates, calibration certificates, and clear terms such as after-sales warranty period (recommended to be ≥ 1 year) and on-site repair response time to avoid being affected in later operation and maintenance.

When selecting, it is necessary to abandon the misconception of "emphasizing price over performance", and focus on the five core points of cleaning uniformity, material reliability, production capacity adaptability, disinfection effectiveness, and after-sales compliance. Combined with the actual needs of the laboratory, a comprehensive evaluation should be conducted to select products with high cost-effectiveness and strong adaptabilityQuick cage cleaning machineEstablish a solid equipment foundation for the sterile environment of experimental animal breeding.
