Abstract

The invention relates to a processing system and technology of yoghourt modified milk powder. The system comprises a raw material bin, a milk clarifier communicating with the raw material bin, a firsttemporary storage tank communicating with the milk clarifier, a homogenizer communicating with the first temporary storage tank, a first falling film evaporator communicating with the homogenizer, asecond temporary storage tank communicating with the first falling film evaporator, a fermentation tank group communicating with the second temporary storage tank, a second falling film evaporator communicating with the fermentation tank group, a spray drying tower communicating with the second falling film evaporator, a cooling bed communicating with the spray drying tower and a collecting tank communicating with the cooling bed. During evaporation in the spray drying tower, a driving device is started to drive an isolating membrane to vibrate, and when milk forms powder on the inner wall ofthe isolating membrane and the powder hangs on the wall, the milk powder is vibrated by the driving device to fall off, so that the wall hanging amount of the milk powder on the inner wall of the isolating membrane is effectively reduced; and the system has the effects of reducing bacterium breeding on the inner wall of the spray tower and increasing the effective utilization rate of equipment.

Description

technical field

[0001] The present application relates to the field of dairy product processing, in particular to a processing system for preparing yoghurt milk powder and a processing technology thereof. Background technique

[0002] Modified milk powder usually refers to milk powder with corresponding nutritional elements added according to the needs of different groups of people. That is, fresh milk is sterilized directly (or after skimming) and then added with corresponding nutritional elements, dissolved evenly and then sprayed with powder, which can achieve the design ratio of nutrition corresponding to the needs of different groups of people.

[0003] In the production process of milk powder, it is necessary to use a pressure spray drying tower to dry and separate the milk powder. In the use of spray drying towers in the industry, milk powder often adheres to the inner wall of the spray tower, and then combines with the water vapor in the drying tower. Caking on the ...
