Is there any difference between solid state brewing and liquid brewing?

The main difference is that the nature is different, the process is different, the characteristics are different, as follows:

A, nature is different

1, solid state fermentation

Solid State Fermentation is the microorganisms in the absence of or basically no free water on the solid substrate fermentation method method.

2, liquid fermentation

Liquid method of liquor is based on grains, potatoes, molasses and other raw materials, by liquid fermentation, distillation into edible alcohol process route, and then by the string of aroma, blending, blending and become.

Two, the process is different

1, solid-state fermentation

Mostly in the absence or almost absence of free water in the presence of a certain humidity in the water-insoluble solid substrate, with one or more microbial fermentation of a biological reaction process.

2. Liquid Fermentation

It is a series of technological processes using edible alcohol as the alcohol base.

Three, the characteristics are different

1, solid-state fermentation

①, low water activity, high water insolubility of the substrate, microbial growth, high enzyme activity, enzyme system is rich.

②, the fermentation process is rough, without strict aseptic conditions.

3, equipment structure is simple, less investment, low energy consumption, easy to operate.

4, simple post-treatment, less pollution, basically no wastewater discharge.

2, liquid fermentation method

①, the production of rice husk and other auxiliary materials, not only can reduce production costs, reduce labor intensity, but also to avoid the use of auxiliary materials to the product into the evil smell.

②, the production can control the saccharification and fermentation temperature in the optimal degree, which is the solid cellar fermentation method can not do, especially at high temperatures under the production of harmful components furfural.

3, liquid aldehydes can be transported by pipeline electric pump, both clean and safe, and easy to set up mechanical equipment and computerized management.

④, the liquid method will be made of raw materials into alcohol, and then processed into white wine, in the process of preparation, according to the market needs, according to the arrangement of different high and low degrees of alcohol, different aromas and tastes, so that the factory products are suitable for the different requirements of different regions.
