Russian Applications of Belt Filters in Brewer’s Grain Dehydration
Brewer’s grains are a byproduct of the beer brewing process. They have a high water content and are difficult to store or further process without treatment. By using a belt filter for dehydration, the water content of the brewer’s grains can be effectively reduced, facilitating their subsequent treatment (such as feed processing or energy utilization). Belt filters are widely used in brewer’s grain dehydration. Due to their high efficiency, continuous operation, and convenience, they have become one of the important equipment for solid-liquid separation processes in the beer industry. The following are the applications of belt filters in brewer’s grain dehydration.
The Significance of Brewer’s Grain Dehydration
Resource utilization: Dehydrated brewer’s grains are easier to process into animal feed, fermentation raw materials, or used for energy purposes (such as biogas fermentation) due to their lower water content.
Reduce storage and transportation costs: Reduce the volume and weight of brewer’s grains, improve storage efficiency, and reduce long-distance transportation costs.
Environmental benefits: By reducing the water content of brewer’s grains, its corruption rate is reduced, and odor and environmental pollution are reduced.
Brewer’s Grains Dehydration Process
Material conveying
Brewer’s grains are evenly distributed on the filter belt through the conveying device, and the materials are spread evenly through the distributor to avoid concentrated load.
Gravity dehydration
The material enters the gravity dehydration zone. In the primary dehydration stage, gravity is used to make the free water in the brewer’s grains seep out and be discharged from the bottom of the filter belt.
Wedge dehydration
The brewer’s grains after gravity dehydration enter the wedge zone, and are further squeezed and dehydrated under the action of the gradual tightening of the filter belt, preparing for entering the high-pressure zone.
High-pressure extrusion
After entering the high-pressure zone, the brewer’s grains are subjected to higher pressure under the action of multiple pressing rollers, and finally the water content is squeezed to the target content.
Filter cake discharge
After dehydration, the dried brewer’s grains are transported to the discharge port by the filter belt and unloaded by the scraper. At the same time, the filter belt is automatically cleaned by the cleaning device to prepare for the next cycle.
Advantages of Belt Filter in Brewer’s Grain Dehydration
High-efficiency dehydration capacity
The belt filter uses the continuous extrusion of the filter belt and multi-stage pressure regulation to achieve rapid dehydration of the brewer’s grain. After treatment, the moisture content of brewer’s grain can be greatly reduced, significantly reducing its volume and transportation costs.
Continuous operation, high production capacity
The belt filter is a continuously operating equipment suitable for the processing needs of large quantities of by-products in breweries. It can achieve uninterrupted dehydration and meet the requirements of industrial production.
The high degree of automation
The equipment is equipped with an automatic cleaning device and control system, which can ensure the cleanliness of the filter belt, reduce the cost of manual maintenance, and ensure the stability and efficiency of equipment operation.
Strong adaptability of processing volume
The belt filter can flexibly adjust the model and configuration according to the scale of the brewery to meet the needs of different production volumes.
Conclusion
The application of belt filters in brewers’ grain dehydration not only increases the added value of by-products but also achieves a win-win situation in terms of economic and environmental benefits, providing strong support for the sustainable development of the beer industry.
