Stainless steel KEG tank with a volume of 100 litres

The basis of the device is a stainless steel KEG tank with a volume of 100 litres, made of corrosion-resistant steel suitable for food contact. The stainless steel design provides good durability during regular use and facilitates the cleaning of the interior space. Due to its larger volume, the device is designed for processes requiring a higher capacity than smaller 30l or 50l distillation sets. The tank is equipped with a prepared connection for the distillation column, a capillary for the temperature sensor, and a bottom drain valve. However, the total volume of 100 litres does not automatically represent the maximum working fill – the actual fill must comply with the safety requirements of the specific process and the manufacturer's instructions.

Wide filling neck with a diameter of 12 cm

A great practical advantage of this model is the wide filling opening with a diameter of 12 cm, which facilitates access to the tank. Compared to narrow-neck containers, it allows for more convenient filling, emptying, and subsequent cleaning of the internal walls. The wide opening is particularly appreciated during regular maintenance, when it is important to remove any deposits and keep the tank clean. The design also allows for the connection of a corresponding distillation column using a connecting system designed for the specific tank version.

Column with internal reflux and six cold fingers

One of the main technical advantages of the Edest KEG 100 l device is the distillation column with internal reflux, equipped with six so-called cold fingers. These consist of cooling elements made from pipes with a diameter of 12 mm, which contribute to the partial cooling of the rising vapours inside the column. During this process, part of the vapour condenses, and the resulting liquid returns back into the column. This phenomenon is known as reflux and is important for the repeated contact between the rising vapours and the returning condensate. The cold fingers do not serve as the main outlet cooler, but are part of the internal reflux system. The resulting condensate at the outlet of the device is cooled by a separate water cooler.

Split distillation column with a height of 120 cm

The distillation column has a total height of 120 cm and a diameter of 60.3 mm. The manufacturer divides it into two main parts – a lower section approximately 70 cm high and an upper section with the column head 50 cm high. This design facilitates disassembly, transport, storage, and access to the internal packing during cleaning. The split construction also allows for different column configurations within the technical possibilities of the specific assembly. Individual joints must be properly sealed and assembled according to the manufacturer's documentation. An advantage is also the possibility of easier maintenance without the need to handle the column as a single, long, non-detachable part.

Copper and stainless steel column packing

Included in the package is 0.5 litres of copper prismatic springs and nine stainless steel scrubbing pads, which form the packing of the distillation column. Their purpose is to create a larger contact surface for the rising vapours and returning condensate. Copper is also used in distillation systems due to its interaction with certain sulphur compounds, while the stainless steel packing offers a durable construction and easier maintenance. The correct placement and quantity of the individual types of packing must correspond to the manufacturer's instructions, as excessive compaction or clogging can restrict column throughput.

Two separately adjustable cooling circuits

The Edest KEG 100 l distillation apparatus utilises two cooling circuits with independent water flow regulation. One serves the internal reflux system with cold fingers, the other serves the main condenser. Each circuit has its own regulation valve, allowing the cooling intensity in individual parts of the equipment to be adjusted as needed. The manufacturer also provides a distributor, reinforced water hoses, and a quick connector for linking to a suitable water source. Proper cooling function is essential for safe operation and requires checking the hose permeability, the tightness of joints, and the availability of a sufficient amount of cooling water.

Water cooler with a 300 cm spiral

Part of the assembly is a water-cooled condenser with an internal spiral 300 cm in length, made from a tube with a diameter of 8 mm. The cooler serves to remove heat from the vapours passing through the distillation system and their subsequent condensation. Thanks to the spiral arrangement, it offers a longer contact path for heat exchange within a compact space. Cooling efficiency depends on operating conditions, the temperature of the incoming water, and its flow rate. The manufacturer states that the design is focused on efficient heat transfer and reasonable cooling water consumption, although specific consumption for this model is not defined.

600 ml sludge remover

The distillation column is complemented by a 600 ml sludge remover, which is equipped with a separate 3/8″ drain valve. This design element serves to collect selected liquid components and condensate in the corresponding part of the distillation system. Thanks to the drain valve, the container can be emptied more conveniently once the equipment has been safely shut down and cooled. The sludge remover is a separate component of the assembly and must not be confused with the main cooler or the tank drain valve. To maintain proper function, it is important to check its cleanliness, tightness, and flow.

Electronic and analogue thermometer

The Edest KEG 100 l comes with two thermometers, which allow the monitoring of operating temperatures in different parts of the assembly. The electronic thermometer with a framed display is used to measure the vapour temperature in the upper part of the column, while the analogue bimetallic thermometer provides an additional control measurement. Both the tank and the column head have prepared measuring points for the corresponding sensors. This allows the operator to continuously monitor temperature conditions without the need to interfere with the closed parts of the system. The presence of thermometers does not, however, imply automatic control of the entire process.

Bottom drain valve 3/4″

A 3/4″ ball drain valve is located at the bottom of the stainless steel tank, allowing for more convenient emptying of the contents after operation. The manufacturer uses a stainless steel connection nipple and a corresponding ball valve for this part. This solution is particularly practical for the larger 100l tank, as it is not necessary to handle the entire vessel for the purpose of emptying it. The valve may only be used by following a safe procedure, particularly after shutting off the heat and allowing the equipment and liquid to cool.

External gas heating

This distillation apparatus model is designed for heating using a separate gas burner. Unlike electrical variants, it does not have its own electric heating elements as standard equipment. The heating intensity is therefore controlled via a suitable external heat source, which must correspond to the tank dimensions and the safety requirements of the equipment. The gas burner is purchased separately; when selecting one, it is important to consider the stability of the vessel, the required power, the type of gas, and the correct connection.

Dimensions and spatial requirements of the assembly

The assembled distillation apparatus has a total height of approximately 185 cm, while the column itself measures 120 cm. Given the tank volume and the height of the equipment, it is necessary to choose a sufficiently spacious, stable, and safe location before installation. It is necessary to account not only for the dimensions of the still itself, but also for the placement of the gas burner, the cooling water lines, and access to the regulating valves. The surface must be solid and suitable for the load of the tank, especially when filled. Planning must also include adequate ventilation and safe conditions for the operation of the gas equipment.

Safe Use and Maintenance

The distillation apparatus combines a heated liquid, vapour lines, and water cooling. When operating with a gas burner, an open flame is present; therefore, it is necessary to follow the safety instructions of both the equipment manufacturer and the chosen burner. Ensure sufficient ventilation, stable positioning of the tank, leak-tight connections, and the uninterrupted function of the cooling system. Outlets and vapour lines must not be blocked, and the apparatus must not be used as a closed pressure vessel. The use of flammable liquids or vapours creates a particularly serious fire risk, necessitating appropriate technical safeguards and compliance with relevant regulations. Never leave the equipment unattended during operation.

After operation is complete, the heat source must be safely switched off and all components left to cool down completely. Only then can disassembly, cleaning, and maintenance be performed. Regularly check the silicone seals, connecting elements, cooling hoses, and valves. Keep the copper and stainless steel packing clean according to the manufacturer's instructions to avoid restricting the flow through the column.
