Key points for selecting disc dryer

Processing capacity: Select the dryer model that can meet the material processing capacity based on the production scale and output requirements. Generally, factors such as the initial moisture content of the material, the moisture content after drying, and production time need to be considered to determine the hourly or daily processing capacity of the dryer.

Material characteristics: including the form of the material (such as powder, granular, paste, etc.), thermal sensitivity, viscosity, bulk density, etc. Materials with different characteristics have different requirements for the structure and operating conditions of the dryer. For example, thermosensitive materials require the selection of a disc dryer that can dry at lower temperatures and is equipped with a precise temperature control system.

Dry temperature and humidity requirements:

Determine the heating temperature range and dehumidification method of the dryer based on the properties of the material and the requirements of the drying process. For materials with strict requirements for the moisture content of dried products, it is necessary to choose a disc dryer with good humidity control capabilities and equip it with corresponding humidity monitoring and adjustment devices.

Energy supply:

Consider the energy supply situation of the factory and choose a suitable heating medium. If the factory has steam supply, a steam heated disc dryer can be selected; If the power supply is sufficient and the cost is low, electric heating dryers can also be chosen. In addition, it is necessary to consider whether the pressure, flow rate, and other parameters of the heating medium match the requirements of the dryer.

Equipment material:

Select appropriate equipment materials based on the corrosiveness and hygiene requirements of the materials. For general chemical materials, carbon steel material can be selected; For corrosive materials, stainless steel or other corrosion-resistant materials should be selected; In the food and pharmaceutical industry, in order to ensure product quality and hygiene safety, it is usually required that equipment be made of stainless steel material that meets food hygiene standards.
