Solar Steam Cooking System

Make cooking Smart, Simple, Comfortable and hygienic by installing Solar Steam Cooking System with Great Fuel Saving.

Wonderful system for steam cooking, direct cooking, steam generation, industrial heating and many other applications. Best ideally suitable for mass cooking in residential schools, hostels, temples, churches, charitable institutions and NGOs.

This system is totally maintenance free and works without any hassle for many years to come with Zero cooking cost.

Subsidy of 30% of the project cost can be availed from MNRE, Government of India and loan with interest rate of 5%.

Working principle of Solar Steam Cooking System:
This Solar Steam Cooking System works based on Scheffler Solar Concentrators which generates heat up to 650 degrees centigrade due to concentration of the sunlight focused on to the receiver for all types of cooking, steam generation and many other applications. Their speciality is a flexible surface curvature and a non-moving focal area. Their use is now becoming increasingly popular in many parts of the world, especially in India.

It is a static receiver technology. The concentrators reflect and concentrate solar rays at one focal point where steam receiver is installed. Number of such a concentrator units can be installed in series as per our energy requirements. The Solar rays falling onto the dish are reflected and concentrated on the receivers placed in its focus. Due to concentration the temperature achieved is very high that is between 450-650 degree centigrade and thus the water in the receivers comes to boiling and steam is generated.

Above the receiver is an insulated header pipe filled half with water. The cold water enters the receiver through inner pipe, gets heated due to the high temperature of the concentrated rays and the heated water goes up. The cold water again enters through inner pipe and the cycle continues till steam is generated. The steam gets stored in the upper half empty portion of the header pipe and pressure keeps on rising. The steam is then sent to kitchen through insulated pipe line.

Water is being filled in to the receivers. Due to the extreme heat at focal point, water inside the receiver boils and produces steam which is being collected from each receiver and stored in a pressurised vessel.

With the reduction in steam pressure from Storage vessel, it is carried and fed to the cooking vessels. The condensate from cooking vessel is again recalculated to the receivers. Thus it is a closed loop system.

A fully automatic electronic tracking (East – west) is provided for individual concentrator. Only seasonal focal adjustment is done manually.

System components

The salient features of the Solar Steam Cooking System are as below:

Cooking possible in the kitchen: Since it is an indirect cooking system with the steam produced outside and brought into the kitchen via standard piping, there is no requirement of cooking in the sun. The existing kitchen can be used with very few modifications.

No need to stand in the heat of the sun: The cooking can be done in the existing kitchen, with only the apparatus outside.

Tracks sun automatically: One operator is required to align the dishes once in the morning.

Cooks faster than other types of solar cookers: The very high temperatures produced result in faster cooking as compared to other solar cooking technologies.

User friendly: It is user friendly, easy to move and clean

Safe & Durable: It is safe to operate and durable

Timing: Effectively useful from one hour after sunrise to one hour before sunset

Clean & Hygiene: The food cooked by solar steam cooking system is tasty, clean & hygienic.

Zero Cost Cooking: This system is totally maintenance free and works without any hassle for many years to come with Zero cooking cost.

Zero Maintenance Cost: This system is totally maintenance free and works without any hassle for many years to come!

Environment Friendly: Solar steam cooking helps reduce the high social, economic, and environmental costs of black shoot and fossil fuel emissions that impact all humans and environments today. In addition, reduction of CO2 and other green house gases, the solar steam cooking ensures a smoke free environment for the cook.
