Description of technology
Industrial bakery oven which use saw dust or paddy husk as fuel is another quality product developed by the National Engineering Research & Development Centre. It provides an effective method of baking bread and other flour based products and can be used in a small bakery. The effective use of rice husk or saw dust reduces the energy cost of baking bread by 75% compared to the conventional method. Although rice husk or saw dust can be used as fuel, it is more suitable to use saw dust as it gives more heat energy. Apart from that, the floor area needed to install this oven is very small. (Approximately 9 sq.ft.) All sides of this oven is properly insulated which offers a quicker heating – up period normally 20 – 25 minutes whereas the conventional method needs almost one hour to heat –up. Consequently, this method reduces the baking time, and there’s no way of entering exhaust gases into baking chambers, which results a clean operation. Easy operation methods reduce maintenance and labour requirement. Dimensions 77 x 62 x 216 cm. Fuel Consumption 3– 4 kg/batch. Capacity 16 Dough/batch Fuel Sawdust or Paddy Husk Baking Time 20 – 25 min
Specific Features
Easy way to enter bakery industry investing very small amount of money : Investment for the commencement of bakery industry using this type of ovens is minimal. Comparatively the operational cost is very small.
