Abstract
An apparatus and method for malting grain having a hollow cylindroconical vessel and a first, smaller removable false bottom retaining grain used in cleaning, steeping and resting the grain and a second, larger removable false bottom used in germinating and kilning the grain. The apparatus also includes a pump, a cooling system, a fan, a heating system, a humidifier, an aeration system, valves, tubing and ducting for treating grain with water and air. Sensors communicate with a controller and control the pump, the cooling system, the fan, the heating system, the humidifier, the valves, and the aeration system.
Claims9
An apparatus comprising:
- a hollow vessel having a vessel bottom and a vessel midsection;
- a first false bottom, removably positioned into a narrow end of the vessel, near the vessel bottom, retaining grain;
- a second false bottom, removably positioned into the midsection of the vessel, retaining grain;
- a fan connected to and in fluid communication with the vessel via top and/or bottom ducting and allowing air flow through the vessel and the first and second false bottom;
- a heating system, in fluid communication with the fan and the vessel via the top and/or bottom ducting to heat air from the fan;
- a humidifier, in fluid communication with the fan and the vessel via the top and/or bottom ducting to humidify the air;
- sensors, to measure temperature and moisture;
- and
- a controller, in communication with the sensors, and controlling the fan, the heating system and the humidifier;
- a first solenoid valve in fluid communication with a water inlet and a second solenoid valve in fluid communication with a water outlet and controlling filling and draining of the vessel with water;
- a pump in fluid communication with the vessel via tubing and allowing water flow through the first false bottom, out of the vessel and back into the vessel;
- a cooling system in fluid communication with the vessel and the pump via the tubing and cooling the water;
- a first valve, removably attached to the vessel bottom and containing water when closed, and providing for air movement when open;
- a second valve connected to and in fluid communication with the fan and the vessel via the top ducting and directing airflow out an exhaust duct or back to the fan;
- an aeration system in fluid communication with the vessel via the tubing and aerating the water;
- wherein the first false bottom is used for cleaning and steeping grain and wherein in the first false bottom, the first valve and the grain are removed from the vessel following cleaning, steeping and resting;
- the second false bottom is inserted into the vessel, and the grain is returned to the vessel for germinating and kilning;
- and
- with the controller, further controlling the first and second solenoid valves, the pump, the cooling system, the first and second valves, and the aeration system.
