Rectification column construction

Tank of the rectification column

Ta   In the hobby version, this is usually a adapted, 30 liter KEG after beer. Can be ordered or welded a tank with a larger capacity, yet much lower height than KEG. Welded sms, tri-clamp, or flange with screw holes will allow you to attach a buffer or a column. When we have the buffer needed there will also be a pipe connector from the buffer to the tank. It is convenient to have a separate the inlet is made of SMS with a borosilicate glass pane. Additionally it can be used to observe the inside of the tank. We also need a welded tube reaching near the bottom of the tank. We will be inserting the probe of the thermometer measuring the temperature of the liquid in the tank. For your own safety, you should install heating electrical at the bottom of the tank. For kegu with a capacity of 30 Two combined heaters with a total output of 3.5-4 KW are sufficient. Their actual efficiency will be lower by several percent. The tank should have a drain with a valve at the bottom for a convenient emptying after completion of the distillation process. A good patent the legs are adjustable to allow for correct verticalisation of the column. Of course the tank should be well insulated with a mats armaflex type.

Stabilization and reinforcement buffer

   The buffer improves overall yield and indirectly the quality of the distillate. It allows for a more stable and faster rectification process, not you have to reduce the reception once set up. Additionally we're preparing the foreground at a higher concentration. Having a buffer in we can easily separate the chases and get back to the next distil the end of the spirit that fills the column. Buffer should have 6-8 percent of the capacity of the actual tank. Have a welded blank tube for the thermometer probe near the bottom to the temperature of the liquid in the buffer could be measured. It is necessary Drainage valve connected by a silicone hose with the tank. Viewfinders enable observation of the behaviour of liquids in buffer during subsequent rectification steps. The buffer should be well heated, and so be set on kegs. If it is connected to the tank with an SMS connector, it should have welded tubes placed in the buffer tank, which additionally they're warming up. Too high buffers, poorly heated ones don't work steady. Sometimes they emptied violently, destabilizing the column. A certain solution to this problem is to bring the ends of the transfer tubes near the bottom of the buffer
The buffer consists of a pipe with a slightly larger diameter than diameter of the column, filled with prismatic springs. Pipe has overflows with which excess liquid flows down to fill from a filled buffer tank. There is a canopy above the pipe causing it, that the liquefied distillate dripping from the column flows into the buffer and fills it up. The buffer also needs to be insulated with armaflex, rubber or foam.

Column with prismatic filling

   The column with a diameter of 60 millimetres is usually screwed with pipe sections of maximum 60 centimetres. Filling with Acid resistant prismatic springs are not compacted then too much and does not cause uncontrolled flooding of the column. Port the thermometer in the column should be placed approximately 20 cm above the tank or a buffer, it conventionally houses the "tenth shelf" and by to indicate this thermometer we are rectifying. The best the filling of the column ensuring high quality of the distillate is prismatic springs made of stainless steel wire. Already 2-3 a centimeter layer of well-made springs is equivalent to one shelf. It is not a fixed value and depends from, among other things, the rate of reception, heating power, stabilization columns. The springs are supported by a support based on a welded wire, be inserted in the milled edge of the SMS. Episode filled with copper springs is usually 20 cm long and wears the name of the catalyst. Copper effectively neutralizes messy smells and harmful compounds - but you need it cleaning regularly. The filled pipes are also carefully insulated with a mat.

OLM-Reduced liquid management

   The reduced lateral reception is usually 30 cm below the head - This ensures that the spirit is received without the admixture of the foreground, which accumulate in the head and are picked up there by another valve precise. Using OLM allows you to get more heart, much less polluted with foregrounds in relation to the collection with a valve in of the head. This is usually a bowl, or a shelf inside the column with a drain to the outside, for the purpose of receiving the relevant rectification. The valve precise mounted on the drain enables you to set the reflux degree and speed over.

Glass Viewfinder 360

   Viewfinder made of borosilicate glass tube enables comfortable observation of the rectification process, assessment of the reflux intensity. It provides control of flooding of the column.

Heads of the rectification column

   The head has a condenser connected to cold water, providing reflux. The most efficient and simplest to make is a stainless steel corrugated tube. The thermometer's port, thanks to which we have information on the concentration of the foreground. The lake where they gather pre-drive areas, with a precision valve fitted for their drainage. It is important that there is a hole in the head venting. This prevents uncontrolled the pressure increase in the column and the explosion. It's very useful a thermometer to control the temperature around this Ventilation. Thank youIt is important that there is a hole in the head venting. This prevents uncontrolled the pressure increase in the column and the explosion.ki temu you can set the power off in If the temperature rises above a safe value, e.g. in in case of water fading in the cooler.

Aabratek style head

   Aabratek is the simplest and most popular head. Built like the Nixon-Stone head, but mounted almost horizontally. This way, the head height is halved.

Thor's hammer head

   The advantage of this head is even less height. It is important that it is a bull'shorn head, which ensures its proper operation.

Ufo head

   The bottom stubs pipe assembly is very compact, but it can easily accommodate an efficient cooler and a significantly enlarged pond.

Controlling the distillation process

   Arming the distillation column with electronics makes it easier to run and increases safety. More complicated controllers with pressure sensors, flood sensors, probes temperatures almost completely automate the rectification process by controlling the electrovalves, the heating power. After setting the parameters heating up, flooding, foreground discharge, power shift, cooling control, switching off the unit in case of failure, or after completion of the distillation process, it is done automatically. Such the controller can be managed from a laptop or smartphone and enables the distillation process to be controlled at a distance.
The simplest controller should have a temperature reading at least two points. Allow you to set the warm-up power or operating power. Automatically limit the power when the batch is warmed up, Turn off the column in the event of a critical temperature rise in the head.

ARC-Automatic Reflux Control

   The system of electronic control of the rectification process is built of controller, temperature control probes, electrovalve. ARC controls the temperature in the column and closes if it increases the solenoid valve to prevent the reception of a contaminated heart. When the column stabilizes, the controller automatically resumes fractional reception.
