Compared to traditional methods of vinasse treatment such as natural drying, plate and frame filtration, or centrifugal separation, the screw press is reshaping the post-processing workshops of wineries with its unique technological advantages. It is not a mere replacement, but rather brings technological innovation from three dimensions: continuity, energy efficiency, and adaptability.

Its most notable advantage lies in its continuous automated operation. The equipment utilizes a specially designed spiral extrusion technology, automating the entire process from feeding, extrusion, drainage, to discharge, eliminating the need for batch operations and frequent manual intervention. This significantly enhances processing efficiency, reduces labor intensity, and makes large-scale, industrialized processing of distillers' grains feasible. For instance, the processing capacity of the standard model can range from 0.3 tons per hour to over 50 tons per hour, catering to the needs of distilleries of various sizes.

In terms of energy efficiency, its advantages are equally prominent. The equipment primarily relies on mechanical squeezing for dehydration, with power consumption concentrated in the motor that drives the screw shaft. Compared to centrifuges that require vacuum systems or high-speed rotation, its energy consumption is significantly reduced. At the same time, its efficient dehydration capability means that it alleviates the vast majority of the load for potential subsequent drying processes. From the perspective of the overall process chain, the effect of energy saving and consumption reduction is very considerable.

In addition, the screw press has good process adaptability. The discharge end of the equipment is usually designed with an adjustable back pressure device (such as counterweights, hydraulic cylinders, or springs). By changing the discharge resistance, the squeezing force can be flexibly controlled, thus precisely adjusting the dryness and wetness of the discharged filter cake to meet the requirements of different raw materials (such as beer lees and Baijiu lees) or different subsequent uses (feed, fertilizer). Key components such as screws and screens are widely made of corrosion-resistant materials such as 304 stainless steel, ensuring durability and hygienic safety in environments with materials such as lees, which have certain acidity, alkalinity, and corrosivity.
