Parabolic solar cooker
Parabolic Solar Cooker. The Parabolic Solar Burner is the most powerful and useful cooker in the parabolic class!
The Parabolic class has the same application as your stove top at home. A parabolic is used quite differently than the box cooker or panel cooker, mainly because it reaches higher temperatures much faster than any other style cooker.
Most people will use multiple solar cooker styles to accomplish a variety of cooking needs. The Cantina West Parabolic Solar Burner is the perfect addition to the solar cooking collection for those who need a stove top.
A solar parabolic cooker can reach extremely high temperatures, very quickly thus producing the possibility of burning the food if left unattended for any length of time. But if used properly the parabolic will produce great cooking results and replace the need to turn on your stove top kitchen range burners.
The principle difference between the solar ovens and the parabolic is that with an oven or panel cooker you can set your food out in the sun to cook and pretty much leave it. The necessity to adjust the panel and box cooker and to keep an eye on the food is much less with these types of cookers than with a parabolic.
The "Solar Burner" is a full size parabolic designed for most efficient cooking results. (If a parabolic is too small in size it will not produce sufficient heat for the most effective cooking results and the opposite is true if it is too large; the heat therefore would be too intense.) The solar burner has a diameter of five feet (1.5 m), which produces a high output of energy (heat) for very efficient cooking, yet it is not too large in diameter that one would have much trouble reaching the cooking plate.
The focus point of the sun's rays comes together at about thirty inches above the middle, or bottom, of the parabola.
Each of the six rigid, molded steel panels that form the parabola is covered with an adhesive backed reflective vinyl which is quite durable, yet easily repaired or replaced if ever damaged or worn. The reflective film on this solar cooker is the key, or means to the parabolic being able to concentrate the energy from the rays of the sun.
The parabolic is supported by a circular stand (base) and has an easily adjusted crank extension arm to move the elevation tracking of the parabolic up and down, and the whole cooker swivels on its center pole base, allowing for side to side tracking of the sun.
Unlike the solar ovens and panel cookers, there are no darkened pots that come included with the "Solar Burner" parabolic cooker, because in reality there is no need for a "special" pot or pan. A dark pot/pan will give you a little more advantage over a shiny pot, so you might darken the bottom of any shiny pot/pan with high temp bbq paint.
The high temperatures of the parabolic are such that you can use shiny steel pots and pans (those that are more common) but it will give you a little more advantage if you have a dark colored pot/pan. With a parabolic it is more recommendable to use the heavier gauge steel pots, because the thinner variety will scorch and burn your food more easily, especially the thin aluminum, which is also known for health related issues and concerns.
FAQ:
1 Does the entire unit need to turn to follow the sun
The entire unit does not have to turn, but you can track the sun by rotating the entire unit if you like, for this reason it comes with castor wheels that allow for easier rotation and for easier mobility (on hard surfaces of course)
2, What is the adjustment ( up/ down) fore the Cooking platform/ Pot support)?
The elevation adjustment is accomplished by rotating the little handle on the expansion rod mounted on the backside of the parabola. It is designed to be adjusted in increments. The pot recptacle does not need to be adjusted or moved. It is best to leave the pot receptacle as is once you assemble it.
3 how many pounds will the pot /cooking platform support ?
From my own use and experience the pot receptacle can handle up to about 40 lbs, but most cookware and food will usually not come near to that amount of weight under normal cooking conditions.
Once when I used a large enamel canning bath with six bottles of food and the water used for the steam bath, the load I had on the receptacle was about 45 lbs and it was necessary for me to counter balance the whole cooker as well as to brace and to counterweight the cooker so that the pot/pan with all of its weight did not tip the unit over forward.
(we are working on developing an addition to this cooker to allow for larger and heavier pots/pans to be placed on the parabolic. This cooker is powerful enough you can pressure can with it, it just needs some enhancement to allow for greater weight.)
4. About how long to ship from your location to Littleton, Colorado ? To ship from here would require just a couple of days once it left our place. If you order today, it would ship out tomorrow (Wednesday) and arrive within, more than likely, two days
5) How is the 'tracking' of the sun accomplished? In other words, does the whole base ( including the stand ) need to turn or does just the Dish support turn?
The whole unit can be rotated, on the wheels, or you can just rotate the parabola and the mount ring by rotating it on the center axis, or the center post. Both ways work fine. I leave my center post screw loose so that I can rotate it easily
6) Is the height of the cooking platform adjustable and if yes by how much?
The height of the pot receptacle is not adjustable. All parabolics have a set, or determined focal point based on the depth or shallowness of the parabola (dish) so, your focal point distance from the center, or bottom of the parabola will remain the same, thus there is no need to adjust the height of the pot receptacle. This is the case with all parabolic cookers
