Technical column | Wijay invites you to learn about the role of liquid yeast in bread fermentation


From flour to dough

How does flour become dough?

Yeast is a crucial component. It's like the soul of bread, like a baby that needs loving care. If the yeast is served well, then the bread is equivalent to the majority of success, because it directly affects the appearance level, taste and aroma of the bread. There are many types of yeast, but only a few can be used for bread making, and their forms are generally divided into two types: dry yeast and liquid yeast. Liquid yeast is fresh yeast, and its fresh activity is stronger.

The liquid yeast silently drives the whole wonderful fermentation process. It is with the help of liquid medium to complete the fermentation of dough, that is, the yeast is first placed in the liquid medium, propagated in the liquid for several hours, made of fermentation liquid, and then mixed with flour into dough. Commonly known as“One-step process”。

 

Process flow:

Raw material mixing→Liquid fermentation→Heat exchanger→Cold storage→stir→Continuous fermentation→plastic→awakening→bake→cooling→package

Compared with conventional yeast, the liquid fermentation method has higher requirements on the temperature, humidity and cleanliness of its production environment during transportation, storage and production. Wijay technical team designed a new pipeline transportation mode according to the characteristics of liquid yeast, so that liquid yeast can be transported in a closed and clean pipeline to reduce external environmental interference, and automated pipeline transportation mode can also better control the precise ratio of liquid yeast and flour, so that its mixing is more scientific and efficient, from raw materials processing to finished product packaging can realize all automatic and continuous production; The storage life of bread was improved and the aging speed was delayed. The fermentation time is shortened and the production efficiency is improved.
