Knowledge Base

Q

Food industry sludge dewatering stacking machine model Comprehensive consideration is required. The primary factor is the processing capacity, which needs to be determined based on the daily and peak sludge volume (measured in cubic meters per hour), with a margin of about 20% reserved to cope with fluctuations. The second is the target of mud solid content, and the higher the requirement (such as ≥ 25%), the higher the required processing capacity or extrusion stage number of the machine model may be. The nature of sludge is crucial,

Q

In the food processing industry, sludge treatment has always been a difficult problem. Taking a large food factory as an example, the daily production of a large amount of sludge originally relied on traditional plate and frame filter presses for treatment, which not only had low efficiency and relied heavily on manual labor, but also brought enormous pressure to the subsequent disposal process due to the large equipment footprint and time-consuming operation. With the introduction of the stacked screw sludge dewatering machine,

Q

The cost of filter press and screw press needs to be compared from multiple aspects:   Equipment purchase cost   -Filter press: The price of plate and frame filter press is relatively affordable, especially for small plate and frame filter press, which may cost around tens of thousands of yuan. However, if it is a large, highly automated or special material filter press (such as a box filter press), the price may reach
