| IN THE GARAGE | ||||||||||||||||||||||||||||||||||||
| -------------------------- | ||||||||||||||||||||||||||||||||||||
| Still using the old hand cranked revolving plate grain grinder with some modifications: It is mounted on a frame, and powered my a 120 rpm gear motor. A hopper with a slide valve on the bottom feeds the malt into the grinder. The ground malt runs into grain sacks. I used to have a flapper switch inside the small hopper to automatically shut of the motor when it was out of grain, but the switch broke. I am thinking about using some sort of photo cell for the auto shut off feature. | ||||||||||||||||||||||||||||||||||||
| GRAIN GRINDER | ||||||||||||||||||||||||||||||||||||
| -------------------------- | ||||||||||||||||||||||||||||||||||||
| Two 220l food grade plastic barrels, with 3500 watt electric heaters and a home made tempurature contoller. Insulated with what ever I had, styrofoam, rigid fiberglass insulation and covered with poly and packing tape. With output valves, and plastic tubing for calibrated sight tube. I need to build low water shut off, as I have burnt out about 4 or 4 elements in the last 3 years. Even with 3500 watts per tank it takes 4 or more hours to get the water up to 85-95 C, so I fill them the night before and set the tempurature. | ||||||||||||||||||||||||||||||||||||

| Plastic food grade barrel, insulated with 1.5 inch thick styrofoam, then wrapped with poly and packing tape. No heating system so I use boiling water infusions, added from bottom for tempurature steps. The false bottom was a lot of work. Rigid copper tubing spaced about1.5 inches apart making a square grid about 1.5 feet square with 1.4 inch holes drilled on inside. The top is covered with stainless steel mesh and the bottom with plexiglass. Good effeciencies though. To mash in the hopper from the grain grinder hangs from a bracket above mashtaun, and a pipe directs the grain through a sprayer to wet the grain as it runs into the mash. While there is a large loss of heat it makes mashing in way less work. I now use about 90C water to mash in around 67-68C. | ||||||||||||||||||||||||||||||||||||
| MASH TAUN (220 L) | ||||||||||||||||||||||||||||||||||||
| -------------------------- | ||||||||||||||||||||||||||||||||||||
| As I don't have enough room for a gravity system I have to pump out of the mashtaun. To help reduce stuck mashes, the output of the mash runs into a small 3L clear plastic container which has a float to control the pump which sucks out of the vessel. The homemade electronic controller detects the float position by infared beams, to start and stop the pump. | ||||||||||||||||||||||||||||||||||||

| A 400L stainless steel kettle. Scrap from local pulp mill. Came with legs, sight tube, lid and threaded fittings. The wort is pumped into the mash via the outlet. The hop screen is 5 feet of copper tubing with small holes drilled in it towards the back and slightly towards the bottom of the kettle. | ||||||||||||||||||||||||||||||||||||

| BURNER BTU's=lots | ||||||||||||||||||||||||||||||||||||
| A three strip burner I believe came out of a small furnace for a trailer. It was jetted for natural gas. I jetted it down and used a high pressure tiger torch regulator. It really puts out the heat, and sucks back the propane. | ||||||||||||||||||||||||||||||||||||
| -------------------------- | ||||||||||||||||||||||||||||||||||||
| VENT SYSTEM | ||||||||||||||||||||||||||||||||||||
| With the burner putting out lots of fumes, I built a large hood which covers all of the kettle top, and swings up for access via a counter weight. The 10 inch fan is mounted in the wall vents through the wall just under the eve. | ||||||||||||||||||||||||||||||||||||
