When it comes to gentle product homogenization or the processing of solid mixtures, solid–liquid mixtures, or pasty mixtures, BHS batch mixers are an excellent choice. The spectrum ranges from powder mixers to heavy-duty designs. Even small quantities can be fed by manually adding them to the mixer. Highly abrasive products also used for construction are processed in machines protected by a special hard-metal plate lining welded to the interior. A common application in the food-feed industry is the preparation of baking mixes. By using special mixing elements and additionally installed shearing heads, the flour and water base substances, as well as other ingredients, are mixed at high viscosity, completely free of lumps and within the shortest time.
BHS vertical mixers are in operation across all industries. Depending on your application, they process dry or wet, free-flowing, or sticky products. In the food sector, the gentle production of spice blends is a classic application. In the pharmaceutical industry, BHS vertical mixers are used for the production of APIs, while the production of cellulose is the most common application in the chemical industry. The conical mixers are perfectly suited to nearly any mixing task, and the heated version can also be used as a dryer, reactor, or evaporator.

Large throughput rates despite a small installation size – this is precisely what the BHS ring layer mixer is built to deliver. One application example is micro granulating in the chemical industry, for example, in the field of detergent production. Here, poorly flowing powders are transformed into a highly fluid product through micro granulation. In the area of pulp processing, our annular layer mixers come into their own, for instance, when it comes to preparing suspensions (solids plus solution) that serve as base material for subsequent staple fibers production. Compared to conventional systems, the ring layer mixer achieves very rapid decomposition of the individual fibers in the solution. In the pulp and pastes production processes of the food industry, the decisive argument for the ring layer mixer is that it offers optimum hydro neutralization of the product, for example, using steam.
Benefits at a glance:
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 AVA 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.
Benefits at a glance:
The product fed into the machine comes into direct contact with the heated drying elements (drum, head ends and/or shaft, and shovels) and is continuously shifted by the rotating agitator. Half-pipe coils or double jackets are available for heating the drum. Thermal oil or steam are most commonly used as heating fluid, or an electric heater can be used for high-temperature applications.
The constant circulation along the heated surfaces leads to uniform moisture expulsion and creates a uniform temperature and product humidity in the drying mixer product chamber. Vapors are removed via vapor filter systems specially constructed by BHS. The shape and angle of the shovels ensure optimal heat exchange between product and side wall. Separately driven choppers dissolve lumps, thus resulting in a fine-grained to powdered material consistency. Benefits include very short drying times, which can be further reduced by including a vacuum dryer in the design.s
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.

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.
The indexing belt filter of type BF is a continuously operating, horizontal vacuum filter used for the efficient and gentle separation of sedimenting solids from suspensions. The filter cake formed on the conveyor belt can be further processed in many ways, and this versatility is what makes the indexing belt filter stand out. Moreover, the individual filtrates can be recovered and processed separately.
The pressure plate filter of type PF is a filter that operates in a discontinuous manner. The plate-shaped filter elements are arranged as a plate stack in a pressure vessel. The process steps typically performed with this unit are filtration, washing, drying and discharge. All these steps take place under pressure. The filter is used primarily for cake-forming solid-liquid separation of suspensions with a low solids content that are moderately or very difficult to filter. It is also suitable for adsorptive filtration (as a deep bed or precoat filter). The pressure plate filter is frequently used for clarifying filtration. It is a compact unit, operates fully automatically and delivers high throughput rates.
