Tag: PID controller
In June 2009 I purchased the SousVideMagic 1500B and my review was globally very positive.
In August 2009 FreshMealsSolutions spread the information about a new product, a “Bubbler” called FreshMealsMagic (FMM). Prior to the launch of the FMM, this new device has been commented in this post.
I also have to admit that I was doubting on the capability of the FMM to stabilize in an accurate way a waterbath.
The core product of FreshMealsSolutions is the SousVideMagic PID controller (now the 1500D version). In my opinion, the main improvement of this PID controller version is the 2nd digital screen (green screen on the above picture). Setting the temperature and the cooking time becomes easier and “readable”. A second screen indicating the cooking time is a function that is strangely not implemented on most Immersion Circulators.
The bubbler (FMM) can be summarized as a heater element together with a probe and a hose expulsing air. The FMM replaces the usual ricecooker plugged to the SousVideMagic. Therefore the FMM offers the possibility to use pots of any size. Potentially the FMM and the SVM become highly versatile.
The Bubbler solution (contrary to immersion circulators that are using a circulation pump) needs a new device to pulse the air: a small air pump (see on the 2 above pictures). For non American users, the input power cord and an adaptor for the pump should be purchased in you own country (approx. EUR 20 alltogether).
I tested the temperature accuracy of the FFM together with the SousVideMagic controller. As from now I made a technical test without cooking food stuff. For that purpose I used my Thermoworks K type thermometer. The test was conclusive. I tried to find cold spots (once again this test was done without any plastic pouches) and globally the temperature was almost the same everywhere.
Regarding temperature stability: I filled the container with 12 liters of water at 35°C (starting temperature). I set the PID controller to 56°C. The SVM 1500D is 2,000 W and therefore reached the target temperature quickly. I haven’t tuned the SVM and the stability of the temperature was nevertheless very good (in the range from (55.9°C to 56.3°C).
To sum up:
- This new sous vide kit makes FreshMealsSolutions entering in the world of the versatile sous vide equipments.
- Temperature accuracy is very good (I have not especially insulated the container at the occasion of this review).
- Temperature stability seems good but I should do futher tests cooking some food.
- I like the possibility to check the temperature and the cooking time at the same time!
- Main drawback: this sous vide piece of equipemnt is composed of 3 devices and 7 cables…what a mess!
Cost of the SousVideMagic 1500D (PID Controller) + FreshMealsMagic (Bubbler):
- SousVideMagic 1500D: USD 160
- FreashMealsMagic: USD 140
- Sending costs to Europe: USD 110
- Custom duties (Europe): EUR 50
- Input power cord and socket adaptor: approx EUR 20.
Grant total (1 EUR = 1.25 USD): approx. EUR 372 (USD 446).
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”.”
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.
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.
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?
