Spray dryer is a common industrial equipment, which can spray liquid materials into small particles and dry them in hot air flow to obtain dried granular products. It is widely used in pharmaceutical, chemical, food and other industries. This article will introduce the relevant knowledge and precautions for purchasing a spray dryer.
How Spray Dryers Work
The spray dryer is mainly composed of a spray system, a drying system, a collection system, and a control system. Its working principle is to spray the liquid material into small particles through the nozzle, dry in the hot air flow, evaporate the water, and obtain the dried granular product. In the spray dryer, parameters such as temperature, flow rate and humidity of the hot gas flow need to be properly controlled to ensure the quality of the final product.
Specifications And Parameters Of The Spray Dryer
Before purchasing a mini spray dryer machine, it is necessary to determine the required specifications and parameters. First, the nature of the material and output requirements need to be considered. Different materials have different requirements on drying temperature, humidity, flow rate and other parameters, so it is necessary to choose suitable equipment according to the actual situation. Second, yield requirements need to be considered. The output of the spray dryer is usually calculated by the quality and output of the dried product, and it is necessary to select suitable equipment according to actual needs. In addition, factors such as the energy consumption of the equipment, the area occupied by the equipment, and the ease of maintenance of the equipment also need to be considered.
When considering the nature of materials and output requirements, the following factors can be referred to:
Chemical properties of materials:
Including material composition, density, viscosity, PH value, thermal stability, etc. These factors will affect the adhesion, fluidity, volatility and other characteristics of the material, thus affecting the drying effect of the spray dryer.
The physical properties of the material:
Including particle size, shape, color, crystallinity, solubility, etc. of the material. These factors will also affect the drying speed, drying efficiency and other parameters of the material.
Material output requirements:
Different production scales require different equipment capacities and processing speeds, so it is necessary to select the appropriate spray dryer model according to the actual output requirements.
The purpose of the material:
Different materials have different uses, and the subsequent processing and application environment of the materials need to be considered. For example, some materials may need to meet special hygiene standards or environmental protection requirements, and it is necessary to choose a spray dryer that meets the relevant standards.
Technical parameters of spray dryer:
It is necessary to know the working temperature, feed volume, output volume, thermal efficiency and other parameters of the spray dryer in order to choose the appropriate equipment. At the same time, factors such as equipment maintenance and operating costs also need to be considered.
Choose the right supplier
Why it is recommended to choose FBL supplier. First of all, we are a supplier with a certain scale and strength, which can ensure the quality of products and after-sales service. Secondly, it is necessary to understand the supplier’s after-sales service guarantee, including equipment installation, commissioning, maintenance, etc. Finally, our prices are very reasonable.
Pay Attention To The Safety Of The Spray Dryer
During the operation of the spray dryer, some safety issues need to be paid attention to. First of all, you need to pay attention to the grounding of the equipment to ensure that the equipment is well grounded. Secondly, it is necessary to pay attention to the personal safety of the operator to avoid damage to the operator by hot air flow or equipment. In addition, it is also necessary to pay attention to the maintenance of the equipment, and regularly maintain and maintain the equipment to avoid equipment failure.
Consider the maintenance and replacement of the spray dryer
Spray dryer is a long-term use of industrial equipment, so it is necessary to consider the maintenance and replacement of equipment. When purchasing a spray dryer, it is necessary to understand the supplier’s after-sales service guarantee, as well as the warranty period and scope of the equipment. At the same time, the cost of repair and replacement of equipment needs to be understood in order to adequately budget and plan.
Pay attention to the environmental protection of the spray dryer
During the operation of the spray dryer, a certain amount of waste gas and waste water will be generated, and environmental protection issues need to be paid attention to. When purchasing a spray dryer, you need to understand the equipment’s discharge standards and discharge pipeline design to ensure that the equipment meets environmental protection requirements. At the same time, it is necessary to pay attention to the treatment of waste gas and waste water and the selection of treatment equipment during operation.
Consider the degree of automation of the spray dryer
With the development of science and technology, the degree of automation of spray dryers is getting higher and higher, and functions such as automatic control and remote monitoring can be realized. When purchasing a spray dryer, it is necessary to consider the degree of automation of the equipment and the performance of the control system to improve production efficiency and product quality.
Many factors need to be considered when purchasing a spray dryer, including the working principle, specifications and parameters of the equipment, the choice of suppliers, safety issues, maintenance and replacement, environmental issues, and the degree of automation. Only by fully considering these factors can you choose a spray dryer that suits you, improve production efficiency, reduce costs, and improve product quality.
