Precision Spray Drying for Consistent Powder Quality

The duration depends on the machine model. For example, the LPG-100 model takes approximately 1 hour per batch. Other models may have different processing times based on their capacity and specifications.

The key differences are based on the type of material and production requirements:
For emulsified and homogenized materials containing oil, a pressure spray dryer is more suitable, as it handles higher production volumes. For example, the smallest HaiJiang machine has a water evaporation capacity of 50kg per hour, but it is more expensive.
For oil-free materials, a centrifugal spray dryer is preferred, especially for lower production volumes. For example, the LPG-5 model has a water evaporation capacity of 5kg per hour and is more affordable.

There are three heating methods: electric heating, thermal oil heating, and steam heating. For the smallest model, electric heating is recommended due to its efficiency and suitability for lower production capacities.

Given that milk has an 85% water content, the LPG-5 spray dryer can produce approximately 0.9 kg of milk powder per hour. Over a 24-hour period, this translates to around 21.6 kg of milk powder, depending on continuous operation conditions.
