The purpose of dry granulator

Dry granulation is a new type of granulation technology. Compared with wet granulation, dry granulation requires less equipment, lower cost, less floor space, and is more environmentally friendly. At present, the dry granulator is widely used in the granulation of pharmaceutical, food, chemical and other industries, especially suitable for the granulation of materials that are easy to decompose or agglomerate when exposed to moisture and heat.

For the wet granulator, the machine can pass through the screen to grind the wet powder raw material into granules, and it can also pulverize the dry bulk material to the required granules. It can also be widely used to pulverize the compressed bulk material. It becomes a ready-made pellet. However, this equipment is not suitable for solid, liquid, slurry or grinding purposes. It is worth mentioning that, compared with the dry granulator, the wet granulator needs to add a binder (water, starch, etc.), and also needs to be dried. It is often used in granules such as beverage granules, popping candy granules, Chinese medicine granules and so on.

The boiling granulator is mainly due to the continuous drying of the material by the hot air, which evaporates the water in the pellets and solidifies the binder. This process is repeated continuously to form ideal and uniform microporous spherical particles. This machine is a one-step granulator that integrates mixing, granulating, and drying in the same airtight container. Due to the sealed granulation of the equipment, it prevents pollution caused by contact with the outside world, and is more suitable for milk powder, coffee, cocoa, granular juice, etc.

In summary, when users select granulating equipment for granulation processing, they need to use appropriate granulating equipment according to the needs of food processing technology and the characteristics of the product itself. For example, dry granulator is more inclined to granulate materials that are easily decomposed, easy to absorb moisture, and heat sensitive when exposed to moisture; wet granulator is more suitable for granulating wet powder materials.

In which areas will the dry granulator industry develop in the future? The industry believes that in the future, dry granulators are required to meet the requirements of cleanliness and functional flexibility. On the one hand, creating a completely closed dry granulation system can reduce dust pollution during the production process, thereby reducing the risk of pollution.
