Polyscience compaires an immersion circulator and a non stired water bath
by jean-francois on Jan.23, 2010, under Equipement, Time and Accurate Temperature
Today Polyscience made the demonstration that a non stired water bath cannot be as efficient as an immersion circulator. It is funny to see that Polyscience directly mentions Sousvidesupreme in the TAG of the article.
Polyscience video indicates clearely that a non stired water bath has a longer response time to reach the desired core temperature. Therefore, it is obvious that Douglas Baldwin cooking tables sould be used with care. Douglas Baldwin indicates in the Pratical Guide to Sous Vide “With all these digital controllers, I highly recommend setting the temperature offset (measured near the temperature at which you wish to cook) using a high quality digital thermometer. Indeed, at the default settings the thermistors used in the above controllers can easily be off 2–4°F (1–2°C)”.
Freshmealsolutions mentions clearely in the user manual of the SousVideMagic : “If you don’t have a proper food core temperature sensor probe, always cook at desired core temperature settings for the duration as specified by reliable recipes with an additional safety factor of at least 25% longer…”
In addition the manual indicates “The default settings are designed to overshoot 1 or 2 degree higher for safety reasons. You can reduce the overshoot by making your own PID adjustments. See the document “PID Tuning”.”

FreshMealsMagic – Next Pid Controller (incl. bubbler) by Fresh Meals Solutions
by jean-francois on Aug.28, 2009, under Equipments & Accessories
Sousvidecooking.com mentioned some weeks ago fresh news about next Fresh Meal Solutions’ PID controller called Freshmealsmagic!
Fresh Meals Solutions is well known for providing the most price competitive PID controller dedicated to sous vide at home. I purchased and tested Sousvidemagic 1500B. I have to admit I was very satisfied about it.
For your information the global cost for my SousVideMagic 1500B was:
- SousVideMagic 1500B: USD 169 + USD 25 = USD 194 incl. sending to Europe
- Custom duties: EUR 35
- Basic rice cooker: EUR 45
- Input power cord and socket adaptor: approx EUR 16.
Grant total (1 EUR = 1.4 USD): approx. EUR 234 (USD 327)
This article indicates next Fresh Meals Solutions’ equipment will keep the original appliance (the PID Controller) but add a new device: an immersible bubbler.
Fresh Meals Solutions replaces the rice cooker by the built-in immersible bubbler which has 2 functions: heating the water of any kind of container and stirring water so that the heat is spread evenly in the pot.
I personally think this is a great evolution of Fresh Meals Solutions products and expect this product being sold below 200 USD. The release of this new sous vide equipment has not been disclosed to date.

The SWID, Addélice immersion circulator on Youtube
by jean-francois on Jul.17, 2009, under Equipments & Accessories
Addélice launched a short video about its new immersion circulator dedicated to sous vide cooking.
This sous vide equipment is named SWID and benefits from two displays: one for the temperature and the other one probably for the timer. The Youtube video doesn’t show much but you can guess Addélice thermal circulator includes a protection cage. We still don’t know what would be the price of this appliance. I’ll try to contact Addélice to obtain futher information and will inform you if I have some fresh news.

by jean-francois on Jul.08, 2009, under Equipments & Accessories, General Topics
Addélice twitted yesterday and mentioned some new information about their immersion circulator to be released mid-August.
- Microprocessor controlled
- PID temperature control
- Precision ≤ 0.2ºC
- heating power 2.000 Watt
- Timer function
- Overheating protection and low water level protection
- Acoustic and optical alert
- Circulation pump
Addélice mentions on its online shop that their sous vide appliance will be price competitive…
Here a picture taken from their site supposed to represent Addélice immersion circulator…maybe a protection grid?

Addélice, a new Immersion Circulator Manufacturer entering the sous vide cooking market?
by jean-francois on Jun.24, 2009, under Equipments & Accessories
Such information is so rare on the sous vide cooking “planet” that it mustn’t go unnoticed.
Immersion circulator manufacturer are historically laboratories equipment suppliers. Some of these suppliers have slightly adapted their thermal circulators to comply with sous vide cooking needs (refer to Molecularcuisine.org list and price comparison of immersion circulators). It is true that no cook need a machine that can heat above 100°C (212°F) as only water should be used for sous vide cookery. Some immersion circulators can even heat liquids at 200 or 300°C (392-572°F)!
Nevertheless the design of these machines dates back to the eighties and lab equipment manufacturers still have the “monopoly” of the sous vide cooking market.
It seems things are changing and, if the information is true, a new supplier enters the small club of sous vide cooking manufacturers. Contrary to some companies that only relabelled others products, Addélice seems to have designed its own immersion circulator. Addélice internet site is not very talkative
but indicates that their immersion circulator is a pure product from Addélice and will be price competitive. Addélice immersion circulator should be released mid August.
Wait and see…
