What are the advantages of air suspension blower in food processing?

Analysis of the core advantages of air suspension blower in the field of food processing

With the technology of non-contact suspension bearing, high-speed permanent magnet synchronous motor and oil-free operation design, air suspension blower meets the strict requirements of cleanliness, energy consumption control and process stability in food processing field. Compared with traditional roots blower and ordinary centrifugal blower, it has obvious advantages in health and safety, operation efficiency and operation and maintenance cost, and has become an ideal equipment for key processes such as food fermentation, drying, ventilation and dust removal. The specific advantages are as follows:

1. Clean operation without oil to ensure food hygiene and safety.

Food processing requires extremely high cleanliness of production environment and process media. The air suspension blower adopts the design of "air bearing+oil-free lubricating motor", and no lubricating oil is involved in the operation process, thus avoiding the risk of food pollution caused by lubricating oil leakage of traditional oil-containing blowers from the source. The air it conveys is pure and oil-free, which can directly contact with food raw materials or production environment. It is perfectly suitable for processes requiring aeration fermentation such as beer fermentation, yogurt production and condiment brewing, as well as scenes directly related to food hygiene such as ventilation in aseptic workshops and food cooling. At the same time, there is no mechanical contact and wear inside the equipment, and impurities such as metal chips will not be produced, which further guarantees the cleanliness of the production environment, meets the requirements of GMP (Food Production Quality Management Standards) and HACCP food safety system, and reduces the risk of enterprise quality control.

Second, the characteristics of high efficiency and energy saving can reduce the production and operation costs.

Food processing industries (such as large-scale fermentation, continuous drying, storage and ventilation) need fans to run continuously for a long time, which accounts for a high proportion of energy consumption, and the energy-saving advantage of air suspension blowers is particularly prominent. It adopts high-speed permanent magnet synchronous motor (efficiency ≥95%) and precise frequency conversion control system, which can realize stepless adjustment of air volume by 0-100% according to process requirements and avoid energy consumption waste of traditional fan "big horse-drawn cart"-in beer fermentation process, aeration air volume can be adjusted in real time according to dissolved oxygen concentration in fermentation tank, which is 30%-40% more energy-saving than roots fan; In the food drying process, it can accurately match the drying temperature and humidity requirements and reduce the energy consumption of hot air transportation. Taking a condiment factory with a daily output of 100 tons as an example, after replacing the traditional fan with air suspension blower, the annual power saving can reach more than 500,000 kWh, which significantly reduces the operating cost of enterprises and enhances the market competitiveness of products.

Three, low noise and low vibration operation, optimize the production environment.

Food processing workshops (such as pastry making and beverage filling workshops) strictly control noise pollution. The noise of traditional fans is usually above 90dB, which not only affects the physical and mental health of operators, but also may interfere with the operation of precision testing equipment. The air suspension blower reduces the mechanical friction through the non-contact suspension bearing, the running noise is ≤80dB (some models are as low as 75dB), the vibration amplitude is < 2mm/s, and it can meet the workshop noise standard without installing additional sound insulation cover. Its low noise and vibration characteristics can improve the production environment, reduce the labor intensity of operators, avoid the influence of vibration on peripheral equipment (such as measuring instruments and packaging machinery), and ensure the stability of production technology, especially suitable for scenes such as aseptic workshops and precision machining workshops that are sensitive to the environment.

Fourth, the operation is stable and reliable, reducing the risk of production downtime.

Food processing technology (such as continuous fermentation and assembly line drying) requires high equipment continuity, and shutdown will lead to raw material loss, production interruption and major economic losses. The core components of air suspension blower (suspension bearing, motor) have no mechanical contact wear, the service life is more than 10 years, and the failure rate is much lower than that of traditional blower. The equipment is equipped with intelligent monitoring system, which can monitor parameters such as bearing temperature, motor speed, wind pressure and air volume in real time, and give early warning of hidden troubles, which is convenient for enterprises to maintain in advance. In addition, the start-up time of the equipment is short (≤30 seconds), which can quickly respond to the requirements of process switching, support unattended operation, reduce manual intervention, further reduce the risk of production interruption and ensure the continuous and stable operation of the production line.

Fifth, adapt to multiple process scenarios and improve the flexibility of process adaptation.

There are various processes in the food processing field, and the requirements for air volume, air pressure and operating environment of fans are quite different. The adaptability of air suspension blowers under wide working conditions can meet the requirements of multiple scenarios: in the fermentation process, stable low-pressure and large-volume aeration (air volume 10-500 m/min, air pressure 0.2-0.8bar) can be provided to ensure microbial growth and metabolism; In food drying (such as grain drying and fruit and vegetable dehydration), it can transport high-temperature clean air (adaptation temperature ≤120℃) to improve drying efficiency and product quality; In the storage ventilation link, continuous ventilation with large air volume and low air pressure can be realized to prevent grain and raw materials from mildew; In dust collection (such as flour processing and biscuit production), dust-containing air can be transported efficiently, and dust recovery can be realized with dust removal equipment, which not only ensures the workshop environment, but also reduces the waste of raw materials. In addition, the equipment is small in size, light in weight and flexible in installation, which can adapt to the compact layout space of the food workshop without complicated foundation construction, thus reducing the installation cost.

Six, green environmental protection, in line with the sustainable development trend of the industry.

With the increasing demand for green and low-carbon development in the food industry, the environmental advantages of air suspension blowers have become increasingly prominent. Its high-efficiency and energy-saving characteristics can reduce carbon emissions and help enterprises achieve the goal of "double carbon"; Oil-free operation avoids the pollution of lubricating oil to soil, water and other environments, and meets the requirements of environmental protection policies; The equipment is made of food-grade compatible materials, and the surface is smooth and easy to clean, and there is no sanitary corner, which is convenient for enterprises to carry out cleaner production audit. At the same time, the core components of the scrapped equipment can be recycled, which has little impact on the environment, conforms to the long-term trend of sustainable development of the food industry and enhances the brand image of the enterprise.

To sum up, air suspension blower perfectly matches the hygiene and safety requirements and production and operation requirements in the field of food processing by virtue of its core advantages of oil-free cleanness, high efficiency and energy saving, low noise and stability, and multi-scene adaptation, which can not only improve the stability of production process and product quality, but also reduce energy consumption and operation and maintenance costs, and become the preferred equipment for food processing enterprises to upgrade.
