KAISER 50 portable smoker
Kaiserova '50' přenosná udírna na dřevo
The KAISER 50 is a portable single-wall stainless-steel cabinet smoker made in Křižanov, Czechia. Its manufacturer lists a wood-fired firebox, glazed door and load up to 10 kg; the details are model-specific.
A small cabinet built for wood smoke
The KAISER 50 is a portable, upright smoker rather than a smokehouse room or a general-purpose European design. Its maker describes a single-wall stainless-steel cabinet with a glazed door, thermometer, air damper and a separate wood-fired firebox at the base. The glass lets the operator watch the food without opening the cabinet; the door and cabinet form the enclosure, while the damper adjusts the smoke path. This is the configuration of one named model, not a claim that all portable smokers share these features.

What the model's numbers mean
Udírny.cz lists the exterior at 39.5 × 80 × 27.5 cm and the chamber at 39.5 × 52.5 × 27 cm. It does not identify which measurement is height, width or depth, so the figures are preserved in the order given rather than reassigned to axes. The listed mass is 14 kg. The maker advertises a load of up to 10 kg and illustrates that rating as about 25 sausages or 12 trout; this is a product capacity claim, not a promise that every food, cut or hanging arrangement will fit or smoke uniformly. The model is also listed for meat and non-meat foods, including cheese, vegetables and salt.

Wood fire, air and seasonal limits
The manufacturer describes a firebox that uses wood and says the unit needs no external power. Smoke flow is adjusted with an air damper. It also describes the cabinet as uninsulated and recommends outdoor use from spring to autumn when ambient temperatures are at least 5 °C. The page lists 150 °C as a maximum operating temperature; it should not be mistaken for a prescribed temperature for a particular food. The maker locates production of its stainless smokers in Křižanov in the Vysočina region of Czechia, and says this model has been made for 30 years without giving a launch year.

A smoker is not a preservation guarantee
The KAISER 50 can support different smoking approaches, but the cabinet's features do not establish a safe process or storage life for the food. Food Standards Scotland treats cold smoking, hot smoking and shelf-life assessment as separate questions for smoked fish. Use a tested method for the specific fish or meat, including its preparation, measured process conditions, cooling and storage; do not treat smoke exposure or the cabinet's maximum temperature as proof of preservation.
