Products
Indexing belt filter (BF)
The indexing belt filter of type BF is a continuously operating vacuum filter that can be used to filter solid suspensions gently and reliably. The suspension is fed from above and the filter cake forms on the belt. A vacuum is applied under the belt, which sucks the filtrate through the belt. The cyclical operation of the belt with stationary vacuum trays ensures sharp filtrate separation. The quality of the filter cake is achieved via further process steps such as washing, steaming, drying or pressing.
Horizontal dryer (HTC-T)
Many production processes generate water and/or solvent-moist intermediate products that must be dried before further processing, distribution, or disposal is possible. Drying is often carried out in two steps: an upstream, less energy-intensive mechanical method for expelling the main moisture (e.g. filter) and the subsequent thermal final drying. BHS horizontal dryers HTC-T and HTK-T are used in the cellulose industry, as dryers for flame retardants in the chemical industry, and for evaporating high-boiling substances (for example, hydrocarbons) from contaminated environmental industry substances under vacuum conditions.
Rotary pressure filter (RPF)
The BHS rotary pressure filter (type RPF) is a continuously operating filter for pressure filtration. It facilitates gas-tight cake handling in a series of separate process steps. Cake treatment can, for instance, comprise single- or multi-stage cake washing and subsequent cake drying. Cake discharge can take place at atmospheric pressure. Application scenarios cover a wide range of industries, including industrial chemicals, fine chemicals, the pharmaceutical industry and the food industry.
Vertical dryer (HVW-T)
BHS vertical dryer application scenarios range from laboratory to large-scale production, and from highly sensitive pharmaceutical applications to rugged environmental engineering. Customers frequently chose this versatile machine type as the basis for tailored solutions. This is a tiny sample of the possible applications: drying of APIs for the pharmaceutical industry, sterilizing of spices in the food industry, drying of ion exchange resins in the chemical industry, as well as coating of iron powder with additives in metallurgic applications. A multitude of process steps can be implemented using BHS vertical dryers.
