An autoclave is a hermetically sealed container designed for preserving food. The excess pressure inside the boiler creates a temperature above 100 ° C, which makes it possible to achieve high quality food.
Pressure gauge, safety valve, thermometer. container made of aluminum or stainless steel, fitting, drill, drill, thread chamfers, sealing tape, metal tube plugged from the bottom side, food rubber seal, four-section clamp, wing nuts, metal strips about 3 mm thick with slots for mounting screws, low thermal conductivity handle
Find a suitable container. As an autoclave, you can use a can, a flask. The main thing is that they are made of food-grade metals - aluminum or stainless steel.
First, drill a hole in the lid of the future autoclave, then cut a thread equal to the outer diameter of the fitting intended for installing the pressure gauge. Screw in the union.
Follow the same procedure to install the safety valve. Instead, it is possible to mount a manual air supply and pressure relief fitting, but this will complicate control over the process. Seal all threaded connections carefully with special tape.
If the installation of a thermometer is envisaged, then a metal tube, muffled from the bottom side, is fixed in the lid under it.
To seal the lid, select a suitable food-grade rubber seal.
Proceed with the manufacture and installation of the cover fixing and holding device. To do this, fasten a clamp, consisting of four sections, on the neck of the container. Install rocking screws with a diameter of 8 mm at the joints of the sections. To press the lid, provide special wing nuts.
Next, on the lid, crosswise install special metal strips, about 3 mm thick, with slots for fastening screws. Fasten the strips together in the center of the intersection. For fastening, use a handle made of any heat-insulating material.
After assembling the autoclave, be sure to pressurize it. To do this, pump air inside and create a pressure equal to the working one. If no air leaks can be heard by ear, leave it for a day and see how the pressure behaves. If there are no problems, then the device is ready for use.
