QUI TRÌNH TRUYỀN THỐNG

VẤN ĐỀ GẶP PHẢI

Using conventional agitators, some aspects of this process present considerable difficulty to the processor:

Hydration of gums and thickeners is one of the most difficult mixing operations. In some cases the solution has to be agitated for a long period to ensure the gum is fully hydrated.
Agglomerates can easily form. These are not easily dispersed using conventional agitators.
Partially hydrated material can build up on the shaft of the mixer and on the vessel wall.
A uniform pre-emulsion is required by the high pressure homogenizer. This is not possible using conventional agitators.
This will result in the product having to be passed several times through the high pressure homogenizer in order to obtain the desired globule size.

ƯU ĐIỂM

After processing with a Silverson mixer, a single pass through a high pressure homogenizer is normally sufficient to achieve the end product.
The high pressure homogenizer can normally be eliminated for spray-dried products.
Typically a globule size of 5-7μm is achievable with a Silverson high shear mixer.
Maximized yield of raw materials as thickening agents are fully hydrated and other ingredients fully dispersed.
Consistent product quality.
Agglomerate-free mix.
Stable emulsion.
Rapid mixing times.

The batch size, formulation, type of ingredients used and the viscosity of the end product dictates which machine from the Silverson product line is suited to individual processing requirements.
