Abstract
IN the Electrical Review of June 6, Mr. Theodore Rich gives a complete description of an apparatus developed particularly in the province of Brandenburg in Germany whereby steamed potatoes are prepared for pig food. The steamer consists of a galvanized cylindrical vessel, with an insulating jacket and lid. It is mounted on bearings like a churn, and is fitted with a tipping–locking lever. Three sizes are made for about 80, 155 and 308 Ib. of potatoes respectively. The potatoes and necessary water are put in at night, and thanks to automatic control, the potatoes are correctly cooked by the early morning. The food keeps warm throughout the day without the apparatus being switched on and the operational cost is low owing to the special low night rates. The apparatus is protected against running dry. It is claimed that the floury product is much liked by stock.
