CONCENTRATOR TYPE SOLAR COOKER

This is 1.5 meter dish (approx) used for concentrating sunlight primarily designed to cook food

Other applications –

  • Domestic : Pressure cooking, Frying, Roasting, Baking
  • General : Rural , Urban, Military, Remote areas, Camps, Hostel, Science Exhibitions
  • Hospitals : Can be used for sterilization

WORKING : 

This solar dish is made up of reflectors which are formed to give a parabolic surface to produce high reflection. When solar radiation falls on the reflector surface, these reflectors focus the suns rays on the cooking platform. The sun’s radiation then get converted into heat which can be used for a wide range of application. The dish can be conveniently rotated around and fixed depending on the sun’s position.

SPECIFICATION : 

  • Capacity – 12 literes
  • MOC – Highly reflective special mettalic
  • Weight – 20 kgs approx
  • Structure – Steel powder coated finish
  • Pot diameter – 300 mm MAX
  • Power – 600 W, 5 Kwh / sq m / day

BOX TYPE SOLAR COOKER

Box-type solar cooker consists of an insulated box, metallic cooking tray sat inside the box, double glass lid on the cooking tray, and a reflecting mirror fitted on the underside of the lid of the box.   The cooking tray is insulated on the sides and bottom.  The incoming solar radiation falls onto the double glass lid and passes through it to strike the blackened cooking pots and the cooking tray.  The heat is absorbed by the blackened surface and gets transferred to the food inside the pots to facilitate cooking.  The mirror reflector is set in such a way to reflect the solar radiation falling on it to the cooker box. Up to four black painted vessels are placed inside the box. The cooker takes 1? to 2 hours to cook items such as rice, lentils and vegetables. The cooker may also be used to prepare simple cakes, roast cashew nuts, dry grapes, etc.  It is an ideal device for domestic cooking during most of the year, except for the monsoon season and cloudy days. It however cannot be used for frying or chapatti making.

Specifications

The Indian Standard (IS 13420: 2000) defines the specifications and the performance parameters of box-type solar cookers.
