FEEDING BOILER Russian patent published in 2019 - IPC A47J27/06 

FIELD: fodder production.

SUBSTANCE: invention relates to devices for preparation of fodder and can be used in farm and personal part-time farms. Feeding vessel comprises housing 1, furnace 2 with heat exchange chamber, doors 3, 4, branch pipe for discharge of combustion products 5, cooking vessel 6. Upper heat exchange surface of furnace 2 is tightly connected to lower heat exchange surface of steam-water jacket 7, which is connected to input of electromagnetic valve 8, and its output is connected to casing 9 of steam jacket 10. Boiling vessel 6 walls and casing 9 form steam jacket 10. Boiler is closed by tight cover 11. Sprayer 12 is arranged at the bottom of boiling vessel 6. Steam jacket 10 comprises safety valve 13 and heat carrier supply and discharge valves 14, 15. In housing 1 there is bellows 16, which cavity is connected with steam jacket 10. Bellows 16 is connected with choke 19 and gas burner 20 by means of lever system consisting of main lever 17 and adjusting levers 18. In upper diametrically opposite points of steam jacket 10 are installed valve for supply of cold water 21 and valve 22 for removal of heated water. Electromagnetic valve 8 is electrically connected to temperature regulator 23.

EFFECT: use of the proposed boiler will allow to save thermal energy due to the heat extraction from the hot fodder, reduce the fodder preparation time to animals feeding due to its forced cooling, wider range of boiler use due to temperature control of temperature of content in boiling vessel.
