Dewatering Spent Grain

Dewatering spent grain is the process of separating the liquid from the solid residue left after the brewing or distillation of grains. It includes barley, wheat, or corn, in the production of beer, whiskey, or other alcoholic beverages. Obviously, it is essential for efficient waste management and utilization of the residual material. To fulfill this need, a screw press dewatering machine is commonly employed. At Tianzhong Machinery, we provide a range of screw press dewatering machines that cater to diverse requirements. Below are more parameters for your reference.

Benefits of Dewatering Spent Grain

Dewatering spent grain can offer several benefits, both from an environmental and economic point. Some of the key benefits include:

Efficient Waste Management

Dewatering helps in reducing the volume of spent grain, making it easier to handle and dispose of. By removing the water content, the overall weight and volume of the spent grain can be significantly reduced, minimizing transportation costs and requirements for storage space.

Moisture Reduction

The water contained of dewatered spent grain is 50-60%, which makes it more effective to further reduce the moisture content by spreading it out or placing it in a drying facility.

Converting Waste into Value-added Products

Spent grain contains valuable nutrients and organic matter. Dewatered spent grains can be utilized for various purposes, such as animal feed, composting, or as a substrate for biogas production. In this way, you can generate additional economic benefits or reduce waste disposal costs.

Environmental Sustainability

Proper management of spent grain through dewatering reduces waste generation and enables the utilization of by-products. It reduces the amount of organic waste sent to landfills and minimizes soil pollution. It helps breweries and distilleries achieve their sustainability goals.

Why Use Beverage Dewatering Separator?

Continuous Operation

Continuous operation is a key feature of screw press machines, allowing for efficient processing of materials. This machine consists of feed hopper, screw, screen, and discharging system. This design ensures continuous flow of material through the machine, enabling high-volume processing of spent grains.

High Dewatering Efficiency

The screw press utilizes mechanical squeezing to extract liquid from the spent grain. The rotating screw applies pressure to the material, effectively squeezing out the water from the solids. This results in a high dewatering efficiency, reducing the moisture content of the spent grain to a desired level.

Robust Construction

The screw and screen of our dewatering machine are built with stainless steel to ensure its longevity and resistance to corrosion and wear. Moreover, the removable casing and cleaning systems simplify routine maintenance.

Versatile Application

Except for spent grains, screw press machines can be used for dewatering a variety of materials, such as food waste, paper pulp, waste vegetables and fruits, etc. They can also be used as juice extractors.


In conclusion, dewatering spent grain using a screw press machine offers numerous benefits for breweries and distilleries. It facilitates efficient waste management by reducing the volume and weight of spent grain, resulting in cost savings for transportation and storage. In addition, it converts spent grain into value-added products to bring additional economic benefits to investors.
