IMPERIAL

PATENT OFFICE.

The purpose of the arrangement shown in the drawing is not to boil the hops in whole cones in the hot wort, as has been the case up to now, but first through the drying apparatus, which is provided with a heating device, at a temperature not above 30 ⁰ R. to dry until it falls apart by itself, and, before it leaves the apparatus, to chop it up completely with a roller.

Also be prepared by an iron frame, which is then filled with stones cork ¹ can be α, the supervisor brick walls with or, as seen in the drawing;

b represents the furnace,

c, on the other hand, the heating tubes that lead the warm gases to the chimney d.

To regulate the temperature, two slides and e .- ^ ₁ are available, so that if yes should be once the heat more than 30 ⁰ R. what the. both thermometers /, and y _a can be seen immediately, the slide e is closed as soon as the slide e _{t is} opened, and then the combustion gases no longer go through the heating pipes, but directly into the chimney.

g is the box that holds the hops. It consists of finely perforated sheet metal and is filled from above through the flap h.

In order to remove the moisture from the hops as quickly as possible , draws i for cold air, which can be regulated, are attached below. The rising water vapors escape through the smoke chimney k; the little lupulin that goes through the perforated filling box when the hops disintegrate remains on the frame, under which cold air can also be passed in order to prevent it from being supplied. After the hops are completely dry, the pusher m is pulled up, the hops fall onto the rake η and are transported into the attached sack by rotating it. Due to the above arrangement, 10 to 1.5 pCt. Hops saved; It has been shown that whole hop cones, brought directly into hot wort, close immediately and are consequently difficult or at least imperfect to extract. By breaking open umbels which have already been boiled and which are still whole, which are always present in abundance, one can establish that very often the valuable lupulin has scarcely been used up.

Claims (1)

Patent claim: The suspended in the kiln and expiring in a hopper made of perforated sheet metal box g, through which the warm air with the aid of the cold trains driven for drying of hops at a temperature of 26-30 ⁰ R. until the same partial falls apart, as does the rotating rake n, which is located in the tip of the funnel and completely crushes the umbels that have not fallen apart. 1 sheet of drawings.
