Domestic outlet of fluidized bed drying equipment

With the application of emerging technologies such as material processing and intelligent control, fluidized bed drying equipment is also facing new opportunities and challenges in the field of traditional domestic equipment. With the implementation of the new version of GMP, fluidized bed drying equipment will be tailor-made according to different products, and with the upgrade of the concept of energy conservation and environmental protection, energy conservation and environmental protection have also become the principle for the selection of fluidized bed drying equipment.

Why Domestic Fluidized Bed Drying Equipment Cannot Progress

As a user of a pharmaceutical company, when building a new project or a workshop, the first consideration is to determine the selection and configuration requirements of the equipment according to the production process and capacity needs, and to make requirements and descriptions for the important components, options, and necessary configurations of the equipment. This helps users get the most cost-effective equipment with minimal investment.

The URS customer requirements for fluidized bed drying equipment have become the technical documents selected by the supplier. The equipment supplier needs to meet the configuration information and conditions proposed in the document. At the same time, the URS proposes technical improvement requirements for the equipment manufacturer.

At present, the domestic DQ requirements for GMP on equipment are very slack, and the equipment demand is part of DQ. The pre-confirmation we know is only a general description of equipment selection, material, and production capacity, and there is no detailed configuration requirement for the equipment. This is also one of the main reasons leading to the delay in the manufacture of domestic equipment, including fluidized bed drying equipment manufacturing, control systems, and processing accuracy.

Fluidized bed drying equipment outlet: tailored to different products

As a user of fluidized bed drying equipment, we are pleased to find that some domestic equipment manufacturers have begun to try to start with detailed equipment customer needs and gradually accept the US FDA, EU, and WHO when comparing domestic equipment with imported equipment. The required URS model is tailor-made according to different products. This is the only way for the development of China's pharmaceutical machinery.

We must make a series of requirements for the equipment when selecting the equipment, including technical feasibility studies with suppliers. The basic principle of fluidized bed drying is that the heated particles are blown into the convective state by the heated air, and the hot air will carry away the evaporated moisture or organic solvent to achieve the drying of the wet particles, which involves the treatment of the air.

At present, many domestic manufacturers of air handling unit configuration: primary filter - electric heating (or steam heating) - fan - medium efficiency filter - fluidized bed dryer, it is so simple. Obviously, this has a great relationship with the needs of users. If the user's request is low, the manufacturer's configuration is also low.

In order to meet the GMP requirements and meet the production needs of various users, the fluidized bed drying equipment needs to be tailored according to different products, so as to better meet the market demand and reduce the quality risk of pharmaceutical production.

Fluidized bed drying equipment selection principle: energy saving and environmental protection

With the upgrade of the concept of environmental protection, the road to green development of pharmaceutical equipment has become a foregone conclusion. The same energy-saving and environmental protection has also become the principle for the selection of fluidized bed drying equipment by companies.

The basic principle of fluidized bed drying is that the heated particles are blown into a convective state by boiling air, and the hot air will carry away the evaporated water or organic solvent to achieve drying of the wet particles. During the operation of the fluidized bed, the trajectory of the internal particle movement is also closely related to the air heat exchange. At present, the air at the bottom is usually blown up so that the particles are convection. The time that the particles stay in the air is the time when the water in the particles evaporates. The scaly air outlet is used at the bottom of the fluid bed drying equipment manufactured by GEA to make the particles spiral upward in the cylinder, effectively increasing the length of the streamline and Air heat exchange time fully utilizes energy.

With the development of fluidized bed drying equipment, China needs to further promote the improvement of institutional mechanisms, support the development of policies and regulatory systems for the development of chemical bed drying equipment industry, improve the efficiency of government services and regulations, and invest in the establishment of chemical bed drying equipment industry by social forces. The enthusiasm is fully mobilized, market players will be self-disciplined, and the development of the bed drying equipment industry will be further strengthened.

We provides a variety of quality tanks and equipment incluing aboveground,underground and vertical propane tanks. Underground tanks allow people to fuel their home directly,these tanks can be incorporated into most landscape designs. They are available in a wide range of sizes,and even large-capacity tanks can be installed with minimal visual intrusion.We usually design two manhole on the surface of the tank body for maintenance.
