vertical drying mixer for plastics, chemicals, pharmaceuticals, food
A vertical drying mixer, also known as a vertical drying blender, is a piece of equipment that integrates the functions of mixing and drying. It is widely used in industries such as plastics, chemicals, pharmaceuticals, and food. Here is an introduction to it:
Structural Features of vertical drying mixer machines
Cylindrical Barrel: Usually, it has a vertical cylindrical structure. The barrel can be made of stainless steel, carbon steel, etc. The inner wall of the barrel is smooth to prevent material adhesion and is easy to clean.
Screw Agitator: It is arranged in the center of the barrel. The screw blade rotates to convey the materials upwards. The shape and pitch of the blade are designed according to the characteristics of the materials to ensure mixing and conveying effects.
Heating and Drying System: It includes a heating source. The heating source can be electric heating. The hot air is blown into the barrel from the bottom or side to contact with the materials for heat exchange.
Discharge Device: Located at the bottom of the barrel, it is used to discharge the dried and mixed materials. There are different forms of discharge devices, such as manual discharge valves and automatic discharge valves.
Working Principle of vertical drying mixer machines
Most vertical drying mixers adopt a spiral mixing principle. The screw spindle rotates to lift the materials from the bottom of the barrel to the top and then scatter them in an umbrella shape, causing the materials to roll up and down in the barrel for uniform mixing. At the same time, a heating system is equipped to introduce hot air, and the moisture in the materials gradually evaporates under the action of the hot air, achieving the effect of simultaneous mixing and drying.
Advantages of vertical drying mixer machines
High - efficiency Mixing and Drying: The materials are in a continuously flowing state during the mixing and drying process, with uniform heat transfer, short drying time, and high efficiency.
Space - saving: The vertical design has a small floor area, which is suitable for factories with limited space.
Easy to Operate and Maintain: It has a simple structure, is easy to control, and the parts in contact with the materials are easy to clean and maintain.
Versatility: It can be used for the mixing and drying of various materials, and some models can also realize functions such as granulation and coating with corresponding modifications.
Applications of vertical drying mixer machines
Plastic Industry: It is used for the drying and mixing of plastic particles, plastic flakes, and color masterbatches.
Chemical Industry: It is suitable for the mixing and drying of chemical powders, granular materials, and slurries.
Pharmaceutical Industry: It is used for the drying and mixing of pharmaceutical intermediates, powders, and granules, especially for products that require high - purity and low - residue.
Food Industry: It can be used for the drying and mixing of food ingredients such as starches, proteins, and flavorings.
